- I think there is at least one moral theory of respectable lineage and good independent credentials that can accommodate such fairly minimal intuitions about us and animals. This is the theory Hume offers us. I do not consider Hume a forerunner of utilitarianism, and therefore what I shall go on to say in defense of Hume is not intended as a defense of any version of utilitarianism. I see Hume to be much closer to Aristotle than to Mill, to be offering us a theory about human virtues, not a theory about utility maximization and the duties that might involve.
- Standards of morality and of justice are what Hume calls "artifacts"; they are neither divinely ordained, nor an integral part of original human nature, nor revealed by pure reason. They are an outcome of the practical experience of mankind, and the sole consideration in the slow test of time is the utility each moral rule can demonstrate toward promoting human welfare. Hume may be called a precursor to Darwin in the sphere of ethics. In effect, he proclaimed a doctrine of the survival of the fittest among human conventions—fittest not in terms of good teeth but in terms of maximum social utility.
- Well, it does not really explain things; in fact the founding fathers of quantum mechanics rather prided themselves on giving up the idea of explanation. They were very proud that they dealt only with phenomena: they refused to look behind the phenomena, regarding that as the price one had to pay for coming to terms with nature. And it is a fact of history that the people who took that agnostic attitude towards the real world on the microphysical level were very successful. At the time it was a good thing to do. But I don't believe it will be so indefinitely. Of course, I cannot produce theorems to that effect. If you go back to, say, David Hume, who made a careful analysis of our reasons for believing things, you find that there is no good reason for believing that the sun will come up tomorrow, or that this programme will ever be broadcast. It's a habit we have, of believing that things will continue very much as they did before. However, it is a fact that this seems to be a good habit! I cannot make that a theorem, because I think Hume's analysis is sound, but nevertheless I do believe it's a good habit, to look for explanations.

- Berkeley, Hume, Kant, Fichte, Hegel, James, Bergson all are united in one earnest attempt, the attempt to reinstate man with his high spiritual claims in a place of importance in the cosmic scheme.

- Hume gives us probably the only comprehensive statement of the legal and political philosophy which later became known as liberalism... Hume's History did probably as much to spread Whig liberalism throughout Europe in the eighteenth century as Macaulay's History did in the nineteenth.
- It is...in his analysis of the circumstances which determined the evolution of the chief legal institutions, in which he shows why a complex civilisation could grow up only where certain types of legal institutions developed, that he makes some of his most important contributions to jurisprudence. In the discussion of these problems his economic and his legal and political theory are intimately connected. Hume is indeed one of the few social theorists who are clearly aware of the connection between the rules men obey and the order which is formed as a result... What he undertakes is to show that certain characteristics of modern society which we prize are dependent on conditions which were not created in order to bring about these results, yet are nevertheless their indispensable presuppositions. They are institutions "advantageous to the public though...not intended for that purpose by the inventors". Hume shows, in effect, that an orderly society can develop only if men learn to obey certain rules of conduct.
- The great sceptic, with his profound conviction of the imperfection of all human reason and knowledge, did not expect much positive good from political organisation. He knew that the greatest political goods, peace, liberty, and justice, were in their essence negative, a protection against injury rather than positive gifts. No man strove more ardently for peace, liberty and justice. But Hume clearly saw that the further ambitions which wanted to establish some other positive justice on earth were a threat to those values... It was not from the goodness of men but from institutions which "made it the interest even of bad men, to act for the public good" that he expected peace, liberty, and justice. He knew that "every man must be supposed a knave"; though, as he adds, "it appears somewhat strange, that a maxim should be true in politics which is false in fact."
- Hume not only laid in his philosophical work the foundation of the liberal theory of law, but in his History of England (1754–62) also provided an interpretation of English history as the gradual emergence of the Rule of Law which made the conception known far beyond the limits of Britain.
- Hume has come closer to a critique of rationalism than any other author I kn[o]w. Again and again I've found in Hume statements of ideas which I had already independently arrived at. I am impressed especially with Hume's account of the formation of social institutions of all kinds.

- Hume noticed clearly the connection of these doctrines to freedom, and how the maximum freedom of all requires equal restraints on the freedom of each through what he called the three 'fundamental laws of nature': 'the stability of possession, of its transference by consent, and of the performance of promises' (1739/1886:11, 288, 293). [...] Hume may have been the first clearly to perceive that general freedom becomes possible by the natural moral instincts being `checked and restrained by a subsequent judgement' according to 'justice, or a regard to the property of others, fidelity, or the observance of promises [which have] become obligatory, and acquire[d] an authority over mankind' (1741, 1742/1886:111, 455). Hume did not make the error, later so common, of confusing two senses of freedom: that curious sense in which an isolated individual is supposed to be able to be free, and that in which many persons collaborating with one another can be free. Seen in the latter context of such collaboration, only abstract rules of property - i.e., the rules of law - guarantee freedom.

- Hume came close to an evolutionary interpretation, even perceiving that 'no form can persist unless it possesses those powers and organs necessary for its subsistence: some new order or economy must be tried and so on, without intermission; till at last some order which can support and maintain itself, is fallen upon'; and that man cannot 'pretend to an exemption from the lot of all living animals [because the] perpetual war among all living creatures' must go on (1779/1886:11, 429, 436). As has been well said, he practically recognised that 'there is a third category between natural and artificial which shares certain characteristics with both' (Haakonssen, 1981:24).

- Humean skepticism should be well distinguished from Greek skepticism. Hume's assumes as basic the truth of the empirical, of feeling, of intuition, and from that base contests general determinations and laws—because they lack justification from sense perception. Ancient skepticism was so far from making feeling and intuition the principle of truth that, on the contrary, it turned first of all against the senses.

- Every one knows that judicious matter and charms of style have rendered Hume's history the manual of every student. I remember well the enthusiasm with which I devoured it when young, and the length of time, the research and reflection which were necessary to eradicate the poison it had instilled into my mind. It was unfortunate that he first took up the history of the Stuarts, became their apologist, and advocated all their enormities... [H]e still continues to be put into the hands of all our young people, and to infect them with the poison of his own principles of government. It is this book which has undermined the free principles of the English government, has persuaded readers of all classes that these were usurpations on the legitimate and salutary rights of the crown, and has spread universal toryism over the land.
- Thomas Jefferson to William Duane (12 August 1810), quoted in Thomas Jefferson, Writings, ed. Merrill D. Peterson (1984), pp. 1228–1229
- It has ever appeared to me, that the difference between the whig and the tory of England is, that the whig deduces his rights from the Anglo-Saxon source, and the tory from the Norman. And Hume, the great apostle of toryism, says, in so many words, note AA to chapter 42, that, in the reign of the Stuarts, “it was the people who encroached upon the sovereign, not the sovereign who attempted, as is pretended, to usurp upon the people.” This supposes the Norman usurpations to be rights in his successors. And again, C, 159, “the commons established a principle, which is noble in itself, and seems specious, but is belied by all history and experience, that the people are the origin of all just power.” And where else will this degenerate son of science, this traitor to his fellow men, find the origin of just powers, if not in the majority of the society? Will it be in the minority? Or in an individual of that minority?
- Hume is a Tory by chance, as being a Scotchman; but not on a principle of duty, for he has no principle. If he is anything, he is a Hobbist.
- Samuel Johnson, quoted in Letters of David Hume to William Strahan (1888)
- I freely admit that the remembrance of David Hume was the very thing that many years ago first interrupted my dogmatic slumber and gave a completely different direction to my researches in the field of speculative philosophy.

- Hume, from whose fascinating narrative the great mass of the reading public are still contented to take their opinions, hated religion so much that he hated liberty for having been allied with religion, and has pleaded the cause of tyranny with the dexterity of an advocate, while affecting the impartiality of a judge.

- Hume's philosophy, whether true or false, represents the bankruptcy of eighteenth-century reasonableness. He starts out, like Locke, with the intention of being sensible and empirical, taking nothing on trust, but seeking whatever instruction is to be obtained from experience and observation. But having a better intellect than Locke's, a greater acuteness in analysis, and a smaller capacity for accepting comfortable inconsistencies, he arrives at the disastrous conclusion that from experience and observation nothing is to be learnt. There is no such thing as a rational belief... We cannot help believing, but no belief can be grounded in reason. Nor can one line of action be more rational than another, since all alike are based upon irrational convictions. This last conclusion, however, Hume seems not to have drawn... It was inevitable that such a self-refutation of rationality should be followed by a great outburst of irrational faith. The quarrel between Hume and Rousseau is symbolic: Rousseau was mad but influential; Hume was sane but had no followers.

- It is therefore important to discover whether there is any answer to Hume within the framework of a philosophy that is wholly or mainly empirical. If not, there is no intellectual difference between sanity and insanity. The lunatic who believes that he is a poached egg is to be condemned solely on the ground that he is in a minority, or rather—since we must not assume democracy—on the ground that the government does not agree with him. This is a desperate point of view, and it must be hoped that there is some way of escaping from it.

- Hume's account of justice is part of a larger account of the moral and political virtues generally. Hume wrote as a philosophical anthropologist, not as a reformer, unlike Bentham and Mill who set out to reform our moral outlook rather than merely to explain it.

- Upon the whole, I have always considered him, both in his lifetime and since his death, as approaching as nearly to the idea of a perfectly wise and virtuous man, as perhaps the nature of human frailty will permit.
- Today, at any leading American university, a Kant, with all his dithering about God, freedom, and immortality, or even a Hume, wouldn't survive a year in graduate school, much less get hired as an instructor.
