Essentialism
Essentialism is the view that objects have a set of attributes that are necessary to their identity. In early Western thought, Platonic idealism held that all things have such an "essence"—an "idea" or "form". In Categories, Aristotle similarly proposed that all objects have a substance that, as George Lakoff put it, "make the thing what it is, and without which it would be not that kind of thing". The contrary view—non-essentialism—denies the need to posit such an "essence". Essentialism has been controversial from its beginning. In the Parmenides dialogue, Plato depicts Socrates questioning the notion, suggesting that if we accept the idea that every beautiful thing or just action partakes of an essence to be beautiful or just, we must also accept the "existence of separate essences for hair, mud, and dirt".
Older social theories were often conceptually essentialist. In biology and other natural sciences, essentialism provided the rationale for taxonomy at least until the time of Charles Darwin. The role and importance of essentialism in modern biology is still a matter of debate. Beliefs which posit that social identities such as race, ethnicity, nationality, or gender are essential characteristics have been central to many discriminatory or extremist ideologies. For instance, psychological essentialism is correlated with racial prejudice. Essentialist views about race have also been shown to diminish empathy when dealing with members of another racial group. In medical sciences, essentialism can lead to a reified view of identities, leading to fallacious conclusions and potentially unequal treatment.
In philosophy
An essence characterizes a substance or a form, in the sense of the forms and ideas in Platonic idealism. It is permanent, unalterable, and eternal, and is present in every possible world. Classical humanism has an essentialist conception of the human, in its endorsement of the notion of an eternal and unchangeable human nature. This has been criticized by Kierkegaard, Marx, Heidegger, Sartre, Badiou and many other existential, materialist and anti-humanist thinkers. Essentialism, in its broadest sense, is any philosophy that acknowledges the primacy of essence. Unlike existentialism, which posits "being" as the fundamental reality, the essentialist ontology must be approached from a metaphysical perspective. Empirical knowledge is developed from experience of a relational universe whose components and attributes are defined and measured in terms of intellectually constructed laws. Thus, for the scientist, reality is explored as an evolutionary system of diverse entities, the order of which is determined by the principle of causality.In Plato's philosophy, in particular the Timaeus and the Philebus, things were said to come into being by the action of a demiurge who works to form chaos into ordered entities. Similarly, many definitions of essence hark back to the ancient Greek hylomorphic understanding of the formation of the things as articulated, for example, by Aristotle. According to that account, the structure and real existence of any thing can be understood by analogy to an artefact produced by a craftsperson. The craftsperson requires hyle and a model, plan or idea in their own mind, according to which the wood is worked to give it the indicated contour or form. Aristotle was the first to use the terms hyle and morphe, developing an account indebted to Plato's. According to Aristotle's explanation, all entities have two aspects: "matter" and "form". It is the particular form imposed that gives some matter its identity—its quiddity or "whatness". Plato was one of the first essentialists, postulating the concept of ideal forms—an abstract entity of which individual objects are mere facsimiles. To give an example: the ideal form of a circle is a perfect circle, something that is physically impossible to make manifest; yet the circles we draw and observe clearly have some idea in common—the ideal form. Plato proposed that these ideas are eternal and vastly superior to their manifestations, and that we understand these manifestations in the material world by comparing and relating them to their respective ideal form. Plato's forms are regarded as patriarchs to essentialist dogma simply because they are a case of what is intrinsic and a-contextual of objects—the abstract properties that make them what they are. One example is Plato's parable of the cave. Plato believed that the universe was perfect and that its observed imperfections came from man's limited perception of it. For Plato, there were two realities: the "essential" or ideal and the "perceived".
Aristotle applied the term essence to that which things in a category have in common and without which they cannot be members of that category. In his critique of Aristotle's philosophy, Bertrand Russell said that his concept of essence transferred to metaphysics what was only a verbal convenience and that it confused the properties of language with the properties of the world. In fact, a thing's "essence" consisted in those defining properties without which we could not use the name for it, rather than those properties without which a thing would not be what kind of thing it actually is. Although the concept of essence was, according to Bertrand Russell, "hopelessly muddled" it became part of every philosophy until modern times. The Egyptian-born philosopher Plotinus brought idealism to the Roman Empire as Neoplatonism, and with it the concept that not only do all existents emanate from a "primary essence" but that the mind plays an active role in shaping or ordering the objects of perception, rather than passively receiving empirical data.
Examples
Naturalism
Dating back to the 18th century, naturalism is a form of essentialism in which social matters are explained through the logic of natural dispositions. The invoked nature can be biological, ontological or theological. It is opposed by antinaturalism and culturalism.Human nature
In the case of Homo sapiens, the divergent conceptions of human nature may be partitioned into essentialist versus non-essentialist positions. Another established dichotomy is that of monism versus pluralism about the matter.Biological essentialism
Before evolution was developed as a scientific theory, the essentialist view of biology posited that all species are unchanging throughout time. The historian Mary P. Winsor has argued that biologists such as Louis Agassiz in the 19th century believed that taxa such as species and genus were fixed, reflecting the mind of the creator. Some religious opponents of evolution continue to maintain this view of biology.Work by historians of systematic biology in the 21st century has cast doubt upon this view of pre-Darwinian thinkers. Winsor, Ron Amundson and Staffan Müller-Wille have each argued that in fact the usual suspects were very far from being essentialists, and that the so-called "essentialism story" in biology is a result of conflating the views expressed and biological examples used by philosophers going back to Aristotle and continuing through to John Stuart Mill and William Whewell in the immediately pre-Darwinian period, with the way that biologists used such terms as species.
Anti-essentialists contend that an essentialist typological categorization has been rendered obsolete and untenable by evolutionary theory for several reasons. First, they argue that biological species are dynamic entities, emerging and disappearing as distinct populations are molded by natural selection. This view contrasts with the static essences that essentialists say characterize natural categories. Second, the opponents of essentialism argue that our current understanding of biological species emphasizes genealogical relationships rather than intrinsic traits. Lastly, non-essentialists assert that every organism has a mutational load, and the variability and diversity within species contradict the notion of fixed biological natures.
Gender essentialism
In feminist theory and gender studies, gender essentialism is the attribution of fixed essences to men and women—this idea that men and women are fundamentally different continues to be a matter of contention. Gay/lesbian rights advocate Diana Fuss wrote: "Essentialism is most commonly understood as a belief in the real, true essence of things, the invariable and fixed properties which define the 'whatness' of a given entity." Women's essence is assumed to be universal and is generally identified with those characteristics viewed as being specifically feminine. These ideas of femininity are usually biologized and are often preoccupied with psychological characteristics, such as nurturance, empathy, support, and non-competitiveness, etc. Feminist theorist Elizabeth Grosz states in her 1995 publication Space, time and perversion: essays on the politics of bodies that essentialism "entails the belief that those characteristics defined as women's essence are shared in common by all women at all times. It implies a limit of the variations and possibilities of change—it is not possible for a subject to act in a manner contrary to her essence. Her essence underlies all the apparent variations differentiating women from each other. Essentialism thus refers to the existence of fixed characteristic, given attributes, and ahistorical functions that limit the possibilities of change and thus of social reorganization."Gender essentialism is pervasive in popular culture, as illustrated by the #1 New York Times best seller Men Are from Mars, Women Are from Venus, but this essentialism is routinely critiqued in introductory women's studies textbooks such as Women: Images & Realities. Starting in the 1980s, some feminist writers have put forward essentialist theories about gender and science. Evelyn Fox Keller, Sandra Harding,
and Nancy Tuana
argued that the modern scientific enterprise is inherently patriarchal and incompatible with women's nature. Other feminist scholars, such as Ann Hibner Koblitz, Lenore Blum, Mary Gray, Mary Beth Ruskai, and Pnina Abir-Am and Dorinda Outram have criticized those theories for ignoring the diverse nature of scientific research and the tremendous variation in women's experiences in different cultures and historical periods.
