Martin Heidegger was a German philosopher and a seminal thinker in the Continental tradition of philosophy. He is best known for contributions to phenomenology, hermeneutics, and existentialism.
In Being and Time, Heidegger addresses the meaning of "being" by considering the question, "what is common to all entities that makes them entities?" Heidegger approaches this question through an analysis of Dasein, his term for the specific type of being that humans possess, and which he associates closely with his concept of "being-in-the-world". This conception of the human is in contrast with that of Rationalist thinkers like René Descartes, who had understood human existence most basically as thinking, as in Cogito ergo sum.
Heidegger's later work includes criticism of the view, common in the Western tradition, that all of nature is a "standing reserve" on call for human purposes.
Heidegger was a member and supporter of the Nazi Party. There is controversy as to the relationship between his philosophy and his Nazism.
Early yearsHeidegger was born in rural Meßkirch, Baden-Württemberg, the son of Johanna and Friedrich Heidegger. Raised a Roman Catholic, he was the son of the sexton of the village church that adhered to the First Vatican Council of 1870, which was observed mainly by the poorer class of Meßkirch. His family could not afford to send him to university, so he entered a Jesuit seminary, though he was turned away within weeks because of the health requirement and what the director and doctor of the seminary described as a psychosomatic heart condition. Heidegger was short and sinewy, with dark piercing eyes. He enjoyed outdoor pursuits, being especially proficient at skiing.
Studying theology at the University of Freiburg while supported by the church, later he switched his field of study to philosophy. Heidegger completed his doctoral thesis on psychologism in 1914, influenced by Neo-Thomism and Neo-Kantianism, directed by Arthur Schneider. In 1916, he finished his venia legendi with a habilitation thesis on Duns Scotus directed by Heinrich Rickert and influenced by Edmund Husserl's phenomenology.
In the two years following, he worked first as an unsalaried Privatdozent then served as a soldier during the final year of World War I; serving "the last ten months of the war" with "the last three of those in a meteorological unit on the western front".
MarburgIn 1923, Heidegger was elected to an extraordinary Professorship in Philosophy at the University of Marburg. His colleagues there included Rudolf Bultmann, Nicolai Hartmann, and Paul Natorp. Heidegger's students at Marburg included Hans-Georg Gadamer, Hannah Arendt, Karl Löwith, Gerhard Krüger, Leo Strauss, Jacob Klein, Günther Anders, and Hans Jonas. Following on from Aristotle, he began to develop in his lectures the main theme of his philosophy: the question of the sense of being. He extended the concept of subject to the dimension of history and concrete existence, which he found prefigured in such Christian thinkers as Saint Paul, Augustine of Hippo, Luther, and Kierkegaard. He also read the works of Wilhelm Dilthey, Husserl, Max Scheler, and Friedrich Nietzsche.
FreiburgIn 1927, Heidegger published his main work Sein und Zeit. When Husserl retired as Professor of Philosophy in 1928, Heidegger accepted Freiburg's election to be his successor, in spite of a counter-offer by Marburg. Heidegger remained at Freiburg im Breisgau for the rest of his life, declining a number of later offers, including one from Humboldt University of Berlin. His students at Freiburg included Hannah Arendt, Günther Anders, Hans Jonas, Karl Löwith, Charles Malik, Herbert Marcuse, Ernst Nolte, and Karl Rahner. Emmanuel Levinas attended his lecture courses during his stay in Freiburg in 1928, as did Jan Patočka in 1933; Patočka in particular was deeply influenced by him.
Heidegger was elected rector of the University on 21 April 1933, and joined the National Socialist German Workers' Party on 1 May. During his time as rector of Freiburg, Heidegger was not only a member of the Nazi Party, but an enthusiastic supporter of the Nazis. There is controversy as to the relationship between his philosophy and his Nazism. He wanted to position himself as the philosopher of the Party, but the highly abstract nature of his work and the opposition of Alfred Rosenberg, who himself aspired to act in that position, limited Heidegger's role. His resignation from the rectorate owed more to his frustration as an administrator than to any principled opposition to the Nazis, according to historians. In his inaugural address as rector on 27 May he expressed his support of a German revolution, and in an article and a speech to the students from the same year he also supported Adolf Hitler. In November 1933, Heidegger signed the Vow of allegiance of the Professors of the German Universities and High-Schools to Adolf Hitler and the National Socialistic State.
Heidegger resigned the rectorate in April 1934, but remained a member of the Nazi Party until 1945 even though the Nazis eventually prevented him from publishing. In the autumn of 1944, Heidegger was drafted into the Volkssturm, assigned to dig anti-tank ditches along the Rhine.
Heidegger's Black Notebooks, written between 1931 and 1941 and first published in 2014, contain several expressions of anti-semitic sentiments, which have led to a re-evaluation of Heidegger's relation to Nazism. Having analysed the Black Notebooks, Donatella di Cesare asserts in her book Heidegger and the Jews that "metaphysical anti-Semitism" and antipathy toward Jews were central to Heidegger's philosophical work. Heidegger, according to di Cesare, considered Jewish people to be agents of modernity disfiguring the spirit of Western civilization; he held the Holocaust to be the logical result of the Jewish acceleration of technology, and thus blamed the Jewish genocide on its victims themselves.
Post-warIn late 1946, as France engaged in épuration légale in its Occupation zone, the French military authorities determined that Heidegger should be blocked from teaching or participating in any university activities because of his association with the Nazi Party. The denazification procedures against Heidegger continued until March 1949 when he was finally pronounced a Mitläufer. No punitive measures against him were proposed. This opened the way for his readmission to teaching at Freiburg University in the winter semester of 1950–51. He was granted emeritus status and then taught regularly from 1951 until 1958, and by invitation until 1967.
Personal lifeHeidegger married Elfride Petri on 21 March 1917, in a Catholic ceremony officiated by his friend, and a week later in a Protestant ceremony in the presence of her parents. Their first son, Jörg, was born in 1919. Elfride then gave birth to in August 1920. Heidegger knew that he was not Hermann's biological father but raised him as his son. Hermann's biological father, who became godfather to his son, was family friend and doctor Friedel Caesar. Hermann was told of this at the age of 14; Hermann became a historian and would later serve as the executor of Heidegger's will. Hermann Heidegger died on 13 January 2020.
Heidegger had a long romantic relationship with Hannah Arendt and an affair with Elisabeth Blochmann, both students of his. Arendt was Jewish, and Blochmann had one Jewish parent, making them subject to severe persecution by the Nazi authorities. He helped Blochmann emigrate from Germany before the start of World War II and resumed contact with both of them after the war. Heidegger's letters to his wife contain information about several other affairs of his.
Heidegger spent much time at his vacation home at Todtnauberg, on the edge of the Black Forest. He considered the seclusion provided by the forest to be the best environment in which to engage in philosophical thought.
A few months before his death, he met with Bernhard Welte, a Catholic priest, Freiburg University professor and earlier correspondent. The exact nature of their conversation is not known, but what is known is that it included talk of Heidegger's relationship to the Catholic Church and subsequent Christian burial at which the priest officiated. Heidegger died on 26 May 1976, and was buried in the Meßkirch cemetery.
Being, time, and ''Dasein''Heidegger thought the presence of things for us is not their being, but in their utility. For instance, when a hammer is used to knock in a nail, we do not attend to the hammer in itself but are aware of it only as a "ready-to-hand" extension of ourselves to achieve a future result: the knocking in of the nail. The past is reduced to a future usefulness. Zuhanden, in which the distinction between subject and object is blurred, is one of three modes of Being that Heidegger identified – the others being Vorhanden, for things that are there but that we don't interact with, and Dasein.
Heidegger claimed philosophy and science since ancient Greece had reduced things to their presence, which was a superficial way of understanding them. One crucial source of this insight was Heidegger's reading of Franz Brentano's treatise on Aristotle's manifold uses of the word "being", a work which provoked Heidegger to ask what kind of unity underlies this multiplicity of uses. Heidegger opens his magnum opus, Being and Time, with a citation from Plato's Sophist indicating that Western philosophy has neglected Being because it was considered too obvious to question. Heidegger's intuition about the question of Being is thus a historical argument, which in his later work becomes his concern with the "history of Being", that is, the history of the forgetting of Being, which according to Heidegger requires that philosophy retrace its footsteps through a productive destruction of the history of philosophy.
The second intuition animating Heidegger's philosophy derives from the influence of Husserl, a philosopher largely uninterested in questions of philosophical history. Rather, Husserl argued that all that philosophy could and should be is a description of experience. But for Heidegger, this meant understanding that experience is always already situated in a world and in ways of being. Thus Husserl's understanding that all consciousness is "intentional" is transformed in Heidegger's philosophy, becoming the thought that all experience is grounded in Sorge, which means the anxiety or worrifulness arising out of concern about the future—referring to the inner state of being as well as external causality of that being. Heidegger also employs two cognates of Sorge: Besorgen, the provision of something for oneself or someone else; and Fursorge, the solicitude or caring for another in need of help. This thicket of meaning around care/concern is the basis of Heidegger's "existential analytic", as he develops it in Being and Time. Heidegger argues that describing experience properly entails finding the being for whom such a description might matter. Heidegger thus conducts his description of experience with reference to "Dasein", the being for whom Being is a question. In everyday German, "Dasein" means "existence." It is composed of "Da" and "Sein". Dasein is transformed in Heidegger's usage from its everyday meaning to refer, rather, to that being that is there in its world, that is, the being for whom being matters. In later publications Heidegger writes the term in hyphenated form as Da-sein, thus emphasizing the distance from the word's ordinary usage.
In Being and Time, Heidegger criticized the abstract and metaphysical character of traditional ways of grasping human existence as rational animal, person, man, soul, spirit, or subject. Dasein, then, is not intended as a way of conducting a philosophical anthropology, but is rather understood by Heidegger to be the condition of possibility for anything like a philosophical anthropology. Dasein, according to Heidegger, is care. The world confronts Dasein with possibilities. It is not completely deterministic; Dasein has choices. But Dasein cannot choose not to face the possibilities presented by the world, including the inevitability of its own mortality. Heidegger in his existential analytic refers to this condition as being "thrown into the world", or "thrownness". The need for Dasein to assume these possibilities, that is, the need to be responsible for one's own existence, is the basis of Heidegger's notions of authenticity and resoluteness—that is, of those specific possibilities for Dasein which depend on escaping the "vulgar" temporality of calculation and of public life.
The marriage of these two observations depends on the fact that each of them is essentially concerned with time. That Dasein is thrown into an already existing world and thus into its mortal possibilities does not only mean that Dasein is an essentially temporal being; it also implies that the description of Dasein can only be carried out in terms inherited from the Western tradition itself. For Heidegger, unlike for Husserl, philosophical terminology could not be divorced from the history of the use of that terminology, and thus genuine philosophy could not avoid confronting questions of language and meaning. The existential analytic of Being and Time was thus always only a first step in Heidegger's philosophy, to be followed by the "dismantling" of the history of philosophy, that is, a transformation of its language and meaning, that would have made of the existential analytic only a kind of "limit case".
That Heidegger did not write this second part of Being and Time, and that the existential analytic was left behind in the course of Heidegger's subsequent writings on the history of being, might be interpreted as a failure to conjugate his account of individual experience with his account of the vicissitudes of the collective human adventure that he understands the Western philosophical tradition to be. And this would in turn raise the question of whether this failure is due to a flaw in Heidegger's account of temporality, that is, of whether Heidegger was correct to oppose vulgar and authentic time. There are also recent critiques in this regard that were directed at Heidegger's focus on time instead of primarily thinking about being in relation to place and space, and to the notion of dwelling, with connections too to architectural theory as impacted by phenomenology.
''Being and Time''Heidegger's first academic book, Being and Time, was published in 1927. He had been under pressure to publish in order to qualify for Husserl's chair at the University of Freiburg; he dedicated the book to Husserl and the success of the work ensured his appointment to the post.
In Being and Time, Heidegger investigates the question of being by asking about the being for whom being is a question. Heidegger names this being Dasein, and he pursues his investigation through themes such as mortality, care, anxiety, temporality, and historicity. It was Heidegger's original intention to write a second half of the book, consisting of a "Destruktion" of the history of philosophy—that is, the transformation of philosophy by re-tracing its history—but he never completed this project.
Later works: The TurnHeidegger's later works, beginning by 1930 and largely established by the early 1940s, seem to many commentators at least to reflect a shift of focus, if not indeed a major change in his philosophical outlook, which is known as "the turn". One way this has been understood is as a shift from "dwelling" in the world to a fixation on more superficial activities, typified by a "will to power" kind of dominion over the world as a mere object. This ontological "turn" can be seen as a shift in priority from Being and Time to Time and Being—namely, from dwelling in the world to doing in the world. However, others feel that this is to overstate the difference. For example, in 2011 Mark Wrathall argued that Heidegger pursued and refined the central notion of unconcealment throughout his life as a philosopher. Its importance and continuity in his thinking, Wrathall states, shows that he did not have a "turn". A reviewer of Wrathall's book stated: "An ontology of unconcealment means a description and analysis of the broad contexts in which entities show up as meaningful to us, as well as the conditions under which such contexts, or worlds, emerge and fade."
Heidegger focuses less on the way in which the structures of being are revealed in everyday behavior, and more on the way in which behavior itself depends on a prior "openness to being." The essence of being human is the maintenance of this openness. This ‘openness to being' can be seen as a basic ability of humans. We experience the world of beings as containing things in which we have an interest or concern. Heidegger contrasts this openness to the "will to power" of the modern human subject, which is one way of forgetting this originary openness.
Heidegger understands the commencement of the history of Western philosophy as a brief period of authentic openness to being, during the time of the pre-Socratics, especially Anaximander, Heraclitus, and Parmenides. This was followed, according to Heidegger, by a long period increasingly dominated by the forgetting of this initial openness, a period which commences with Plato, and which occurs in different ways throughout Western history.
Two recurring themes of Heidegger's later writings are poetry and technology. Heidegger sees poetry and technology as two contrasting ways of "revealing." Poetry reveals being in the way in which, if it is genuine poetry, it commences something new. Technology, on the other hand, when it gets going, inaugurates the world of the dichotomous subject and object, which modern philosophy commencing with Descartes also reveals. But with modern technology a new stage of revealing is reached, in which the subject-object distinction is overcome even in the "material" world of technology. The essence of modern technology is the conversion of the whole universe of beings into an undifferentiated "standing reserve" of energy available for any use to which humans choose to put it. Heidegger described the essence of modern technology as Gestell, or "enframing." He does not unequivocally condemn technology: while he acknowledges that modern technology contains grave dangers, Heidegger nevertheless also argues that it may constitute a chance for human beings to enter a new epoch in their relation to being. Despite this, some commentators have insisted that an agrarian nostalgia permeates his later work.
In a 1950 lecture he formulated the famous saying "Language speaks", later published in the 1959 essays collection Unterwegs zur Sprache, and collected in the 1971 English book Poetry, Language, Thought.
Heidegger's later works include Vom Wesen der Wahrheit, Der Ursprung des Kunstwerkes, Einführung in die Metaphysik, Bauen Wohnen Denken, and Die Frage nach der Technik and Was heisst Denken?. Also Beiträge zur Philosophie , composed in the years 1936–38 but not published until 1989, on the centennial of Heidegger's birth.
Heidegger and the ground of historyIt has been postulated that Heidegger believed the Western world to be on a trajectory headed for total war, and on the brink of profound nihilism, which would be the purest and highest revelation of Being itself, offering a horrifying crossroads of either salvation or the end of metaphysics and modernity; rendering the West a wasteland populated by tool-using brutes, characterized by an unprecedented ignorance and barbarism in which everything is permitted.
He thought the latter possibility would degenerate mankind generally into scientists, workers and brutes, living under the last mantle of one of three ideologies, Americanism, Marxism or Nazism, and an unfettered totalitarian world technology.
Supposedly, this epoch would be ironically celebrated, as the most enlightened and glorious in human history.
He envisaged this abyss to be the greatest event in the West's history because it would enable Humanity to comprehend Being more profoundly and primordially than the Pre-Socratics.
St. Augustine of HippoRecent scholarship has shown that Heidegger was substantially influenced by St. Augustine of Hippo and that Being and Time would not have been possible without the influence of Augustine's thought. Augustine's Confessions was particularly influential in shaping Heidegger's thought.
Augustine viewed time as relative and subjective, and that being and time were bound up together. Heidegger adopted similar views, e.g. that time was the horizon of Being: '...time temporalizes itself only as long as there are human beings.'
Aristotle and the GreeksHeidegger was influenced at an early age by Aristotle, mediated through Catholic theology, medieval philosophy and Franz Brentano. Aristotle's ethical, logical, and metaphysical works were crucial to the development of his thought in the crucial period of the 1920s. Although he later worked less on Aristotle, Heidegger recommended postponing reading Nietzsche, and to "first study Aristotle for ten to fifteen years". In reading Aristotle, Heidegger increasingly contested the traditional Latin translation and scholastic interpretation of his thought. Particularly important was his radical reinterpretation of Book Six of Aristotle's Nicomachean Ethics and several books of the Metaphysics. Both informed the argument of Being and Time. Heidegger's thought is original in being an authentic retrieval of the past, a repetition of the possibilities handed down by the tradition.
The idea of asking about being may be traced back via Aristotle to Parmenides. Heidegger claimed to have revived the question of being, the question having been largely forgotten by the metaphysical tradition extending from Plato to Descartes, a forgetfulness extending to the Age of Enlightenment and then to modern science and technology. In pursuit of the retrieval of this question, Heidegger spent considerable time reflecting on ancient Greek thought, in particular on Plato, Parmenides, Heraclitus, and Anaximander, as well as on the tragic playwright Sophocles.
DiltheyHeidegger's very early project of developing a "hermeneutics of factical life" and his hermeneutical transformation of phenomenology was influenced in part by his reading of the works of Wilhelm Dilthey.
Of the influence of Dilthey, Hans-Georg Gadamer writes the following: "As far as Dilthey is concerned, we all know today what I have known for a long time: namely that it is a mistake to conclude on the basis of the citation in Being and Time that Dilthey was especially influential in the development of Heidegger's thinking in the mid-1920s. This dating of the influence is much too late." He adds that by the fall of 1923 it was plain that Heidegger felt "the clear superiority of Count Yorck over the famous scholar, Dilthey." Gadamer nevertheless makes clear that Dilthey's influence was important in helping the youthful Heidegger "in distancing himself from the systematic ideal of Neo-Kantianism, as Heidegger acknowledges in Being and Time." Based on Heidegger's earliest lecture courses, in which Heidegger already engages Dilthey's thought prior to the period Gadamer mentions as "too late", scholars as diverse as Theodore Kisiel and David Farrell Krell have argued for the importance of Diltheyan concepts and strategies in the formation of Heidegger's thought.
Even though Gadamer's interpretation of Heidegger has been questioned, there is little doubt that Heidegger seized upon Dilthey's concept of hermeneutics. Heidegger's novel ideas about ontology required a gestalt formation, not merely a series of logical arguments, in order to demonstrate his fundamentally new paradigm of thinking, and the hermeneutic circle offered a new and powerful tool for the articulation and realization of these ideas.
HusserlThere is disagreement over the degree of influence that Edmund Husserl had on Heidegger's philosophical development, just as there is disagreement about the degree to which Heidegger's philosophy is grounded in phenomenology. These disagreements centre upon how much of Husserlian phenomenology is contested by Heidegger, and how much this phenomenology in fact informs Heidegger's own understanding.
On the relation between the two figures, Gadamer wrote: "When asked about phenomenology, Husserl was quite right to answer as he used to in the period directly after World War I: 'Phenomenology, that is me and Heidegger'." Nevertheless, Gadamer noted that Heidegger was no patient collaborator with Husserl, and that Heidegger's "rash ascent to the top, the incomparable fascination he aroused, and his stormy temperament surely must have made Husserl, the patient one, as suspicious of Heidegger as he always had been of Max Scheler's volcanic fire."
Robert J. Dostal understood the importance of Husserl to be profound:
Heidegger himself, who is supposed to have broken with Husserl, bases his hermeneutics on an account of time that not only parallels Husserl's account in many ways but seems to have been arrived at through the same phenomenological method as was used by Husserl.... The differences between Husserl and Heidegger are significant, but if we do not see how much it is the case that Husserlian phenomenology provides the framework for Heidegger's approach, we will not be able to appreciate the exact nature of Heidegger's project in Being and Time or why he left it unfinished.
Daniel O. Dahlstrom saw Heidegger's presentation of his work as a departure from Husserl as unfairly misrepresenting Husserl's own work. Dahlstrom concluded his consideration of the relation between Heidegger and Husserl as follows:
Heidegger's silence about the stark similarities between his account of temporality and Husserl's investigation of internal time-consciousness contributes to a misrepresentation of Husserl's account of intentionality. Contrary to the criticisms Heidegger advances in his lectures, intentionality in the final analysis is not construed by Husserl as sheer presence. Yet for all its "dangerous closeness" to what Heidegger understands by temporality, Husserl's account of internal time-consciousness does differ fundamentally. In Husserl's account the structure of protentions is accorded neither the finitude nor the primacy that Heidegger claims are central to the original future of ecstatic-horizonal temporality.
KierkegaardHeideggerians regarded Søren Kierkegaard as, by far, the greatest philosophical contributor to Heidegger's own existentialist concepts. Heidegger's concepts of anxiety and mortality draw on Kierkegaard and are indebted to the way in which the latter lays out the importance of our subjective relation to truth, our existence in the face of death, the temporality of existence, and the importance of passionate affirmation of one's individual being-in-the-world.
Patricia J. Huntington claims that Heidegger's book Being and Time continued Kierkegaard's existential goal. Nevertheless, she argues that Heidegger began to distance himself from any existentialist thought.
Calvin Shrag argues Heidegger's early relationship with Kierkegaard as:
Hölderlin and Nietzscheand Friedrich Nietzsche were both important influences on Heidegger, and many of his lecture courses were devoted to one or the other, especially in the 1930s and 1940s. The lectures on Nietzsche focused on fragments posthumously published under the title The Will to Power, rather than on Nietzsche's published works. Heidegger read The Will to Power as the culminating expression of Western metaphysics, and the lectures are a kind of dialogue between the two thinkers.
The fundamental differences between the philosophical delineations of Heidegger and Adorno can be found in their contrasting views of Hölderlin's poetical works and to a lesser extent in their divergent views on German romanticism in general. For Heidegger, Hölderlin expressed the intuitive necessity of metaphysical concepts as a guide for ethical paradigms, devoid of reflection. Adorno, on the other hand, pointed to the dialectic reflection of historical situations, the sociological interpretations of future outcomes, and therefore opposed the liberating principles of intuitive concepts because they negatively surpassed the perception of societal realities. Nevertheless, it was Heidegger's rationalization and later work on Hölderlin's poems as well as on Parmenides and his consistent understanding of Nietzsche's thought that formed the foundation of postmodern existentialism.
This is also the case for the lecture courses devoted to the poetry of Friedrich Hölderlin, which became an increasingly central focus of Heidegger's work and thought. Heidegger grants to Hölderlin a singular place within the history of being and the history of Germany, as a herald whose thought is yet to be "heard" in Germany or the West. Many of Heidegger's works from the 1930s onwards include meditations on lines from Hölderlin's poetry, and several of the lecture courses are devoted to the reading of a single poem.
Heidegger and Eastern thoughtSome writers on Heidegger's work see possibilities within it for dialogue with traditions of thought outside of Western philosophy, particularly East Asian thinking. Despite perceived differences between Eastern and Western philosophy, some of Heidegger's later work, particularly "A Dialogue on Language between a Japanese and an Inquirer", does show an interest in initiating such a dialogue. Heidegger himself had contact with a number of leading Japanese intellectuals, including members of the Kyoto School, notably Hajime Tanabe and Kuki Shūzō. Reinhard May refers to Chang Chung-Yuan who stated "Heidegger is the only Western Philosopher who not only intellectually understands Tao, but has intuitively experienced the essence of it as well." May sees great influence of Taoism and Japanese scholars in Heidegger's work, although this influence is not acknowledged by the author. He asserts: "The investigation concludes that Heidegger’s work was significantly influenced by East Asian sources. It can be shown, moreover, that in particular instances Heidegger even appropriated wholesale and almost verbatim major ideas from the German translations of Daoist and Zen Buddhist classics. This clandestine textual appropriation of non-Western spirituality, the extent of which has gone undiscovered for so long, seems quite unparalleled, with far-reaching implications for our future interpretation of Heidegger’s work."Lebanese philosopher and architectural theorist Nader El-Bizri, who, as well as focusing on the critique of the history of metaphysics, also moves towards rethinking the notion of "dwelling" in the epoch of the modern unfolding of the essence of technology and Gestell, and realizing what can be described as a "confluence of Western and Eastern thought" as well. El-Bizri has also taken a new direction in his engagement in 'Heidegger Studies' by way of probing the Arab/Levantine Anglophone reception of Sein und Zeit in 1937 as set in the Harvard doctoral thesis of the 20th century Lebanese thinker and diplomat Charles Malik.
It is also claimed that the works of counter-enlightenment philosophers such as Heidegger, along with Friedrich Nietzsche and Joseph de Maistre, influenced Iran's Shia Islamist scholars, notably Ali Shariati. A clearer impact of Heidegger in Iran is associated with thinkers such as Reza Davari Ardakani, Ahmad Fardid, and Fardid's student Jalal Al-e-Ahmad, who have been closely associated with the unfolding of philosophical thinking in a Muslim modern theological legacy in Iran. This included the construction of the ideological foundations of the Iranian Revolution and modern political Islam in its connections with theology.
Heidegger and the Nazi Party
The rectoratewas sworn in as Chancellor of Germany on January 30, 1933. Heidegger was elected rector of the University of Freiburg on April 21, 1933, and assumed the position the following day. On May 1, he joined the Nazi Party.
On 27 May 1933, Heidegger delivered his inaugural address, the Rektoratsrede, in a hall decorated with swastikas, with members of the Sturmabteilung and prominent Nazi Party officials present.
His tenure as rector was fraught with difficulties from the outset. Some Nazi education officials viewed him as a rival, while others saw his efforts as comical. Some of Heidegger's fellow Nazis also ridiculed his philosophical writings as gibberish. He finally offered his resignation as rector on 23 April 1934, and it was accepted on 27 April. Heidegger remained a member of both the academic faculty and of the Nazi Party until the end of the war.
Philosophical historian Hans Sluga wrote:
Though as rector he prevented students from displaying an anti-Semitic poster at the entrance to the university and from holding a book burning, he kept in close contact with the Nazi student leaders and clearly signaled to them his sympathy with their activism.
In 1945, Heidegger wrote of his term as rector, giving the writing to his son Hermann; it was published in 1983:
The rectorate was an attempt to see something in the movement that had come to power, beyond all its failings and crudeness, that was much more far-reaching and that could perhaps one day bring a concentration on the Germans' Western historical essence. It will in no way be denied that at the time I believed in such possibilities and for that reason renounced the actual vocation of thinking in favor of being effective in an official capacity. In no way will what was caused by my own inadequacy in office be played down. But these points of view do not capture what is essential and what moved me to accept the rectorate.
Treatment of HusserlBeginning in 1917, German-Jewish philosopher Edmund Husserl championed Heidegger's work, and helped him secure the retiring Husserl's chair in Philosophy at the University of Freiburg.
On 6 April 1933, the Reichskommissar of Baden Province, Robert Wagner, suspended all Jewish government employees, including present and retired faculty at the University of Freiburg. Heidegger's predecessor as Rector formally notified Husserl of his "enforced leave of absence" on 14 April 1933.
Heidegger became Rector of the University of Freiburg on 22 April 1933. The following week the national Reich law of 28 April 1933 replaced Reichskommissar Wagner's decree. The Reich law required the firing of Jewish professors from German universities, including those, such as Husserl, who had converted to Christianity. The termination of the retired professor Husserl's academic privileges thus did not involve any specific action on Heidegger's part.
Heidegger had by then broken off contact with Husserl, other than through intermediaries. Heidegger later claimed that his relationship with Husserl had already become strained after Husserl publicly "settled accounts" with Heidegger and Max Scheler in the early 1930s.
Heidegger did not attend his former mentor's cremation in 1938. In 1941, under pressure from publisher Max Niemeyer, Heidegger agreed to remove the dedication to Husserl from Being and Time.
Heidegger's behavior towards Husserl has evoked controversy. Arendt initially suggested that Heidegger's behavior precipitated Husserl's death. She called Heidegger a "potential murderer." However, she later recanted her accusation.
In 1939, only a year after Husserl's death, Heidegger wrote in his Black Notebooks: "The more original and inceptive the coming decisions and questions become, the more inaccessible will they remain to this 'race'. Thus, Husserl’s step toward phenomenological observation, and his rejection of psychological explanations and historiological reckoning of opinions, are of enduring importance—yet it never reaches into the domains of essential decisions", seeming to imply that Husserl's philosophy was limited purely because he was Jewish.
Post-rectorate periodAfter the failure of Heidegger's rectorship, he withdrew from most political activity, but remained a member of the Nazi Party.
In a 1935 lecture, later published in 1953 as part of the book Introduction to Metaphysics, Heidegger refers to the "inner truth and greatness" of the National Socialist movement, but he then adds a qualifying statement in parentheses: "namely, the confrontation of planetary technology and modern humanity". However, it subsequently transpired that this qualification had not been made during the original lecture, although Heidegger claimed that it had been. This has led scholars to argue that Heidegger still supported the Nazi party in 1935 but that he did not want to admit this after the war, and so he attempted to silently correct his earlier statement.
In private notes written in 1939, Heidegger took a strongly critical view of Hitler's ideology; however, in public lectures, he seems to have continued to make ambiguous comments which, if they expressed criticism of the regime, did so only in the context of praising its ideals. For instance, in a 1942 lecture, published posthumously, Heidegger said of recent German classics scholarship:
In the majority of "research results," the Greeks appear as pure National Socialists. This overenthusiasm on the part of academics seems not even to notice that with such "results" it does National Socialism and its historical uniqueness no service at all, not that it needs this anyhow.
An important witness to Heidegger's continued allegiance to National Socialism during the post-rectorship period is his former student Karl Löwith, who met Heidegger in 1936 while Heidegger was visiting Rome. In an account set down in 1940, Löwith recalled that Heidegger wore a swastika pin to their meeting, though Heidegger knew that Löwith was Jewish. Löwith also recalled that Heidegger "left no doubt about his faith in Hitler", and stated that his support for National Socialism was in agreement with the essence of his philosophy.
Heidegger rejected the "biologically grounded racism" of the Nazis, replacing it with linguistic-historical heritage.
Post-war periodAfter the end of World War II, Heidegger was summoned to appear at a denazification hearing. Heidegger's former lover Hannah Arendt spoke on his behalf at this hearing, while Karl Jaspers spoke against him. He was charged on four counts, dismissed from the university and declared a "follower" of Nazism. Heidegger was forbidden to teach between 1945 and 1951. One consequence of this teaching ban was that Heidegger began to engage far more in the French philosophical scene.
In his postwar thinking, Heidegger distanced himself from Nazism, but his critical comments about Nazism seem "scandalous" to some since they tend to equate the Nazi war atrocities with other inhumane practices related to rationalisation and industrialisation, including the treatment of animals by factory farming. For instance in a lecture delivered at Bremen in 1949, Heidegger said: "Agriculture is now a motorized food industry, the same thing in its essence as the production of corpses in the gas chambers and the extermination camps, the same thing as blockades and the reduction of countries to famine, the same thing as the manufacture of hydrogen bombs."
In 1967 Heidegger met with the Jewish poet Paul Celan, a concentration camp survivor. Celan visited Heidegger at his country retreat and wrote an enigmatic poem about the meeting, which some interpret as Celan's wish for Heidegger to apologize for his behavior during the Nazi era.
''Der Spiegel'' interviewOn 23 September 1966, Heidegger was interviewed by Rudolf Augstein and Georg Wolff for Der Spiegel magazine, in which he agreed to discuss his political past provided that the interview be published posthumously. In the interview, Heidegger defended his entanglement with National Socialism in two ways: first, he argued that there was no alternative, saying that he was trying to save the university from being politicized and thus had to compromise with the Nazi administration. Second, he admitted that he saw an "awakening" which might help to find a "new national and social approach," but said that he changed his mind about this in 1934, largely prompted by the violence of the Night of the Long Knives.
In his interview Heidegger defended as double-speak his 1935 lecture describing the "inner truth and greatness of this movement." He affirmed that Nazi informants who observed his lectures would understand that by "movement" he meant National Socialism. However, Heidegger asserted that his dedicated students would know this statement was no eulogy for the Nazi Party. Rather, he meant it as he expressed it in the parenthetical clarification later added to Introduction to Metaphysics, namely, "the confrontation of planetary technology and modern humanity."
The eyewitness account of Löwith from 1940 contradicts the account given in the Der Spiegel interview in two ways: that he did not make any decisive break with National Socialism in 1934, and that Heidegger was willing to entertain more profound relations between his philosophy and political involvement. The Der Spiegel interviewers did not bring up Heidegger's 1949 quotation comparing the industrialization of agriculture to the extermination camps. In fact, the interviewers were not in possession of much of the evidence now known for Heidegger's Nazi sympathies. Der Spiegel journalist Georg Wolff had been an SS-Hauptsturmführer with the Sicherheitsdienst, stationed in Oslo during World War II, and had been writing articles with antisemitic and racist overtones in Der Spiegel since war's end.
Influence and reception in FranceHeidegger is "widely acknowledged to be one of the most original and important philosophers of the 20th century while remaining one of the most controversial." His ideas have penetrated into many areas, but in France there is a very long and particular history of reading and interpreting his work which in itself resulted in deepening the impact of his thought in Continental Philosophy. He influenced Jean Beaufret, :fr:François Fédier|François Fédier, Dominique Janicaud, Jean-Luc Marion, :fr:Jean-François Courtine|Jean-François Courtine and others.
Existentialism and pre-war influenceHeidegger's influence on French philosophy began in the 1930s, when Being and Time, "What is Metaphysics?" and other Heideggerian texts were read by Jean-Paul Sartre and other existentialists, as well as by thinkers such as Alexandre Kojève, Georges Bataille and Emmanuel Levinas. Because Heidegger's discussion of ontology is rooted in an analysis of the mode of existence of individual human beings, his work has often been associated with existentialism. The influence of Heidegger on Sartre's Being and Nothingness is marked, but Heidegger felt that Sartre had misread his work, as he argued in later texts such as the "Letter on Humanism". In that text, intended for a French audience, Heidegger explained this misreading in the following terms:
Sartre's key proposition about the priority of existentia over essentia does, however, justify using the name "existentialism" as an appropriate title for a philosophy of this sort. But the basic tenet of "existentialism" has nothing at all in common with the statement from Being and Time —apart from the fact that in Being and Time no statement about the relation of essentia and existentia can yet be expressed, since there it is still a question of preparing something precursory.
"Letter on 'Humanism'" is often seen as a direct response to Sartre's 1945 lecture "Existentialism Is a Humanism". Aside from merely disputing readings of his own work, however, in the "Letter on Humanism" Heidegger asserts that "Every humanism is either grounded in a metaphysics or is itself made to be the ground of one." Heidegger's largest issue with Sartre's existential humanism is that, while it does make a humanistic 'move' in privileging existence over essence, "the reversal of a metaphysical statement remains a metaphysical statement." From this point onward in his thought, Heidegger attempted to think beyond metaphysics to a place where the articulation of the fundamental questions of ontology were fundamentally possible: only from this point can we restore any possible meaning to the word "humanism".
Post-war forays into FranceAfter the war, Heidegger was banned from university teaching for a period on account of his support of Nazism while serving as Rector of Freiburg University. He developed a number of contacts in France, where his work continued to be taught, and a number of French students visited him at Todtnauberg. Heidegger subsequently made several visits to France, and made efforts to keep abreast of developments in French philosophy by way of correspondence with Jean Beaufret, an early French translator of Heidegger, and with Lucien Braun.
Derrida and deconstructioncame to Heidegger's attention in 1967 by way of Lucien Braun's recommendation of Jacques Derrida's work. Heidegger expressed interest in meeting Derrida personally after the latter sent him some of his work. There was discussion of a meeting in 1972, but this failed to take place. Heidegger's interest in Derrida is said by Braun to have been considerable. Braun also brought to Heidegger's attention the work of Michel Foucault. Foucault's relation to Heidegger is a matter of considerable difficulty; Foucault acknowledged Heidegger as a philosopher whom he read but never wrote about..
Derrida attempted to displace the understanding of Heidegger's work that had been prevalent in France from the period of the ban against Heidegger teaching in German universities, which amounted to an almost wholesale rejection of the influence of Jean-Paul Sartre and existentialist terms. In Derrida's view, deconstruction is a tradition inherited via Heidegger. According to Derrida, Sartre's interpretation of Dasein and other key Heideggerian concerns is overly psychologistic, anthropocentric, and misses the historicality central to Dasein in Being and Time.
The Farías debate, Philippe Lacoue-Labarthe, and Jean-François Lyotard, among others, all engaged in debate and disagreement about the relation between Heidegger's philosophy and his Nazi politics. These debates included the question of whether it was possible to do without Heidegger's philosophy, a position which Derrida in particular rejected. Forums where these debates took place include the proceedings of the first conference dedicated to Derrida's work, published as "Les Fins de l'homme à partir du travail de Jacques Derrida: colloque de Cerisy, 23 juillet-2 août 1980", Derrida's "Feu la cendre/cio' che resta del fuoco", and the studies on Paul Celan by Lacoue-Labarthe and Derrida which shortly preceded the detailed studies of Heidegger's politics published in and after 1987.
When in 1987 Víctor Farías published his book Heidegger et le nazisme, this debate was taken up by many others, some of whom were inclined to disparage so-called "deconstructionists" for their association with Heidegger's philosophy. Derrida and others not only continued to defend the importance of reading Heidegger, but attacked Farías on the grounds of poor scholarship and for what they saw as the sensationalism of his approach. Not all scholars agreed with this negative assessment: Richard Rorty, for example, declared that " book includes more concrete information relevant to Heidegger's relations with the Nazis than anything else available, and it is an excellent antidote to the evasive apologetics that are still being published."individuation, and his later "history of being" as an account of collective individuation. He understands many of the problems of Heidegger's philosophy and politics as the consequence of Heidegger's inability to integrate the two.
CriticismHeidegger's influence upon 20th century continental philosophy is unquestioned and has produced a variety of critical responses.
Early criticismsAccording to Husserl, Being and Time claimed to deal with ontology but only did so in the first few pages of the book. Having nothing further to contribute to an ontology independent of human existence, Heidegger changed the topic to Dasein. Whereas Heidegger argued that the question of human existence is central to the pursuit of the question of being, Husserl criticised this as reducing phenomenology to "philosophical anthropology" and offering an abstract and incorrect portrait of the human being.
In 1929 the Neo-Kantian Ernst Cassirer and Heidegger engaged in an influential debate, during the Second Davos Hochschulkurs in Davos, concerning the significance of Kantian notions of freedom and rationality. Whereas Cassirer defended the role of rationality in Kant, Heidegger argued for the priority of the imagination.
Dilthey's student Georg Misch wrote the first extended critical appropriation of Heidegger in Lebensphilosophie und Phänomenologie. Eine Auseinandersetzung der Diltheyschen Richtung mit Heidegger und Husserl, Leipzig 1930.
The [Young Hegelian]s and critical theory-influenced Marxist thinkers, especially György Lukács and the Frankfurt School, associated the style and content of Heidegger's thought with German irrationalism and criticised its political implications.
Initially members of the Frankfurt School were positively disposed to Heidegger, becoming more critical at the beginning of the 1930s. Heidegger's student Herbert Marcuse became associated with the Frankfurt School. Initially striving for a synthesis between Hegelian Marxism and Heidegger's phenomenology, Marcuse later rejected Heidegger's thought for its "false concreteness" and "revolutionary conservatism." Theodor Adorno wrote an extended critique of the ideological character of Heidegger's early and later use of language in the Jargon of Authenticity. Contemporary social theorists associated with the Frankfurt School have remained largely critical of Heidegger's works and influence. In particular, Jürgen Habermas admonishes the influence of Heidegger on recent French philosophy in his polemic against "postmodernism" in The Philosophical Discourse of Modernity. However, work by philosopher and critical theorist Nikolas Kompridis tries to show that Heidegger's insights into world disclosure are badly misunderstood and mishandled by Habermas, and are of vital importance for critical theory, offering an important way of renewing that tradition.
Reception by analytic and Anglo-American philosophyCriticism of Heidegger's philosophy has also come from analytic philosophy, beginning with logical positivism. In "The Elimination of Metaphysics Through Logical Analysis of Language", Rudolf Carnap accused Heidegger of offering an "illusory" ontology, criticising him for committing the fallacy of reification and for wrongly dismissing the logical treatment of language which, according to Carnap, can only lead to writing "nonsensical pseudo-propositions."
The British logical positivist A. J. Ayer was strongly critical of Heidegger's philosophy. In Ayer's view, Heidegger proposed vast, overarching theories regarding existence, which are completely unverifiable through empirical demonstration and logical analysis. For Ayer, this sort of philosophy was a poisonous strain in modern thought. He considered Heidegger to be the worst example of such philosophy, which Ayer believed to be entirely useless.
Bertrand Russell considered Heidegger an obscurantist, writing,
Highly eccentric in its terminology, his philosophy is extremely obscure. One cannot help suspecting that language is here running riot. An interesting point in his speculations is the insistence that nothingness is something positive. As with much else in Existentialism, this is a psychological observation made to pass for logic.
This quote expresses the sentiments of many 20th-century analytic philosophers concerning Heidegger.
Roger Scruton stated that: "His major work Being and Time is formidably difficult—unless it is utter nonsense, in which case it is laughably easy. I am not sure how to judge it, and have read no commentator who even begins to make sense of it".
The analytic tradition values clarity of expression. Heidegger, however, has on occasion appeared to take an opposing view, stating for example:
those in the crossing must in the end know what is mistaken by all urging for intelligibility: that every thinking of being, all philosophy, can never be confirmed by "facts," i.e., by beings. Making itself intelligible is suicide for philosophy. Those who idolise "facts" never notice that their idols only shine in a borrowed light. They are also meant not to notice this; for thereupon they would have to be at a loss and therefore useless. But idolizers and idols are used wherever gods are in flight and so announce their nearness.
Apart from the charge of obscurantism, other analytic philosophers considered the actual content of Heidegger's work to be either faulty and meaningless, vapid or uninteresting. However, not all analytic philosophers have been as hostile. Gilbert Ryle wrote a critical yet positive review of Being and Time. Ludwig Wittgenstein made a remark recorded by Friedrich Waismann: "To be sure, I can imagine what Heidegger means by being and anxiety" which has been construed by some commentators as sympathetic to Heidegger's philosophical approach. These positive and negative analytic evaluations have been collected in Michael Murray, Heidegger and Modern Philosophy: Critical Essays. Heidegger's reputation within English-language philosophy has slightly improved in philosophical terms in some part through the efforts of Hubert Dreyfus, Richard Rorty, and a recent generation of analytically oriented phenomenology scholars. Pragmatist Rorty claimed that Heidegger's approach to philosophy in the first half of his career has much in common with that of the latter-day Ludwig Wittgenstein. Nevertheless, Rorty asserted that what Heidegger had constructed in his writings was a myth of being rather than an account of it.
Contemporary European receptionAlthough Heidegger is considered by many observers to be one of the most influential philosophers of the 20th century, aspects of his work have been criticised by those who nevertheless acknowledge this influence, such as Hans-Georg Gadamer and Jacques Derrida. Some questions raised about Heidegger's philosophy include the priority of ontology, the status of animals, the nature of the religious, Heidegger's supposed neglect of ethics, the body, sexual difference, or space.
Levinas was deeply influenced by Heidegger, and yet became one of his fiercest critics, contrasting the infinity of the good beyond being with the immanence and totality of ontology. Levinas also condemned Heidegger's involvement with National Socialism, stating: "One can forgive many Germans, but there are some Germans it is difficult to forgive. It is difficult to forgive Heidegger."
Heidegger's defenders, notably Arendt, see his support for Nazism as arguably a personal " 'error' ". Defenders think this error was irrelevant to Heidegger's philosophy. Critics such as Levinas, Karl Löwith, and Theodor Adorno claim that Heidegger's support for National Socialism revealed flaws inherent in his thought.
W. Julian Korab-Karpowicz states in the Internet Encyclopedia of Philosophy that Heidegger's writing is "notoriously difficult", possibly because his thinking was "original" and focused on obscure and innovative topics. He concludes that Being and Time "remains his most influential work."
