David Hume
David Hume was a Scottish philosopher, historian, economist and essayist who is known for his highly influential system of empiricism, philosophical scepticism and metaphysical naturalism. Beginning with A Treatise of Human Nature, Hume strove to create a naturalistic science of man that examined the psychological basis of human nature. Hume followed John Locke in rejecting the existence of innate ideas, concluding that all human knowledge derives solely from experience; this places him amongst such empiricists as Francis Bacon, Thomas Hobbes, Locke and George Berkeley.
Hume argued that inductive reasoning and belief in causality cannot be justified rationally; instead, they result from custom and mental habit. People never actually perceive that one event causes another but only experience the "constant conjunction" of events. This problem of induction means that to draw any causal inferences from past experience, it is necessary to presuppose that the future will resemble the past; this metaphysical presupposition cannot itself be grounded in prior experience.
An opponent of philosophical rationalists, Hume held that passions rather than reason govern human behaviour, proclaiming that "Reason is, and ought only to be the slave of the passions." Hume was also a sentimentalist who held that ethics are based on emotion or sentiment rather than abstract moral principle. He maintained an early commitment to naturalistic explanations of moral phenomena and is usually accepted by historians of European philosophy to have first clearly expounded the is–ought problem, or the idea that a statement of fact alone can never give rise to a normative conclusion of what ought to be done.
Hume denied that people have an actual conception of the self, positing that they experience only a bundle of sensations and that the self is nothing more than this bundle of perceptions connected by an association of ideas. Hume's compatibilist theory of free will takes causal determinism as fully compatible with human freedom. His philosophy of religion, including his rejection of miracles and critique of the argument from design, was especially controversial. Hume left a legacy that affected utilitarianism, logical positivism, the philosophy of science, early analytic philosophy, cognitive science, theology and many other fields and thinkers. Immanuel Kant credited Hume as the inspiration that had awakened him from his "dogmatic slumbers".
Early life
David Hume was born on 7 May 1711 , as David Home, in a tenement on the north side of Edinburgh's Lawnmarket. He was the second of two sons born to Catherine Home, and Joseph Home of Chirnside in the County of Berwick, an advocate of Ninewells. Joseph died just after David's second birthday. Catherine, who never re-married, raised the two brothers and their sister on her own.Hume changed his family name's spelling in 1734 because the surname 'Home' was not well known in England. Hume never married and lived partly at his Chirnside family home in Berwickshire, which had belonged to the family since the 16th century. His finances as a young man were very "slender", as his family was not rich; as a younger son he had little patrimony to live on.
Hume attended the University of Edinburgh at an unusually early ageeither 12 or possibly as young as 10at a time when 14 was the typical age. Initially, Hume considered a career in law, because of his family. However, in his words, he came to have:
an insurmountable aversion to everything but the pursuits of Philosophy and general Learning; and while fanceyed I was poring over Voet and Vinnius, Cicero and Virgil were the Authors which I was secretly devouring.
He had little respect for the professors of his time, telling a friend in 1735 that "there is nothing to be learnt from a Professor, which is not to be met with in Books". He did not graduate.
"Disease of the learned"
At around age 18, Hume made a philosophical discovery that opened up to him "a new Scene of Thought", inspiring him "to throw up every other Pleasure or Business to apply entirely to it". As he did not recount what this scene exactly was, commentators have offered a variety of speculations. One prominent interpretation among contemporary Humean scholarship is that this new "scene of thought" was Hume's realisation that Francis Hutcheson's theory of moral sense could be applied to the understanding of morality as well.From this inspiration, Hume set out to spend a minimum of 10 years reading and writing. He soon came to the verge of a mental breakdown, first starting with a coldnesswhich he attributed to a "Laziness of Temper"that lasted about nine months. Scurvy spots later broke out on his fingers, persuading Hume's physician to diagnose him with the "Disease of the Learned".
Hume wrote that he "went under a Course of Bitters and Anti-Hysteric Pills", taken along with a pint of claret every day. He also decided to have a more active life to better continue his learning. His health improved somewhat, but in 1731, he was afflicted with a ravenous appetite and palpitations. After eating well for a time, he went from being "tall, lean and raw-bon'd" to being "sturdy, robust healthful-like." Indeed, Hume would become well known for being obese and having a fondness for good port and cheese, often using them as philosophical metaphors for his conjectures.
Career
Despite having noble ancestry, Hume had no source of income and no learned profession by age 25. As was common at his time, he became a merchant's assistant, despite having to leave his native Scotland. He travelled via Bristol to La Flèche in Anjou, France. There he had frequent discourse with the Jesuits of the College of La Flèche and is likely to have used the college's extensive library.Hume was derailed in his attempts to start a university career by protests over his alleged "atheism", also lamenting that his literary debut, A Treatise of Human Nature, "fell dead-born from the press". However, he found literary success in his lifetime as an essayist and historian, and a career as a librarian at the Advocates Library for the Faculty of Advocates. These successes provided him much needed income at the time. His tenure there, and the access to research materials it provided, resulted in Hume's writing the massive six-volume The History of England, which became a bestseller and the definitive history of England. For over 60 years, Hume was the dominant interpreter of English history. He described his "love for literary fame" as his "ruling passion" and judged his two late works, the so-called "first" and "second" enquiries, An Enquiry Concerning Human Understanding and An Enquiry Concerning the Principles of Morals, as his greatest literary and philosophical achievements. He would ask of his contemporaries to judge him on the merits of the later texts alone, rather than on the more radical formulations of his early, youthful work, dismissing his philosophical debut as juvenilia: "A work which the Author had projected before he left College." Despite Hume's protestations, a consensus exists today that his most important arguments and philosophically distinctive doctrines are found in the original form they take in the Treatise. Though he was only 23 years old when starting this work, it is now regarded as one of the most important in the history of Western philosophy.
1730s
Hume worked for four years on his first major work, A Treatise of Human Nature, subtitled "Being an Attempt to Introduce the Experimental Method of Reasoning into Moral Subjects", completing it in 1738 at age 28. Books 1 and 2 of his treatise were intended to "try the taste of the public", leading to Book 3 Of Morals being published after his feeling that he had "met with success".Although many scholars today consider the Treatise to be Hume's most important work and one of the most important books in Western philosophy, critics in Great Britain at the time described it as "abstract and unintelligible". As Hume had spent most of his savings during those four years, he resolved "to make a very rigid frugality supply deficiency of fortune, to maintain unimpaired independency, and to regard every object as contemptible except the improvements of talents in literature".
Despite the disappointment, Hume later wrote: "Being naturally of a cheerful and sanguine temper, I soon recovered from the blow and prosecuted with great ardour my studies in the country." There, in an attempt to make his larger work better known and more intelligible, he published the An Abstract of a Book lately Published as a summary of the main doctrines of the Treatise, without revealing its authorship. This work contained the same ideas, but with a shorter and clearer explanation. Although there has been some academic speculation as to the pamphlet's true author, it is generally regarded as Hume's creation.
1740s
After the publication of Essays Moral and Political in 1741included in the later edition as Essays, Moral, Political, and LiteraryHume applied for the Chair of Pneumatics and Moral Philosophy at the University of Edinburgh. However, the position was given to William Cleghorn after Edinburgh ministers petitioned the town council not to appoint Hume because he was seen as an atheist.In 1745, during the Jacobite risings, Hume tutored the Marquess of Annandale, an engagement that ended in disarray after about a year. The Marquess could not follow with Hume's lectures, his father saw little need for philosophy, and on a personal level, the Marquess found Hume's dietary tendencies to be bizarre. Hume then started his great historical work, The History of England, which took fifteen years and ran to over a million words. During this time, he was also involved with the Canongate Theatre through his friend John Home, a preacher.
In this context, he associated with Lord Monboddo and other thinkers of the Scottish Enlightenment in Edinburgh. From 1746 Hume served for three years as secretary to General James St Clair, who was envoy to the courts of Turin and Vienna. At that time Hume wrote Philosophical Essays Concerning Human Understanding, later published as An Enquiry Concerning Human Understanding. Often called the First Enquiry, it proved little more successful than the Treatise, perhaps because of the publication of his short autobiography My Own Life, which "made friends difficult for the first Enquiry". By the end of this period Hume had attained his well-known corpulent stature; "the good table of the General and the prolonged inactive life had done their work", leaving him "a man of tremendous bulk".
In 1749 he went to live with his brother in the countryside, although he continued to associate with the aforementioned Scottish Enlightenment figures.
