Hume's Scepticism Revisited

Published online by Cambridge University Press:  15 July 2014

Abstract

I shall situate Hume's scepticism within a broader philosophical and historical context. Firstly, I shall consider the place of Hume's thought within the early modern break with the almost millennium long metaphysical tradition, a break initiated by Descartes. The framework of being structured by a universal order was replaced by the individual human mind that broke free from any higher authority and became an autonomous cognitive agent. Subsequently, the ontological self-evidence of the world or the possibility of adequate knowledge came under sceptical attack. Hume firmly belongs to this discourse and can be seen as the most consistent exponent of this early modern sceptical line. In this light, the ‘New Hume’ claim that Hume was an ontological realist will be shown to be misplaced in principle. Secondly, the strong influence of Pyrrhonism on Hume's philosophy will be considered, together with his concept of mitigated scepticism. The Pyrrhonian legacy is especially noticeable in Hume's acceptance of the weakness of reason and in his emphasis on the instructive role of philosophy – instead of attempting to make it the foundation of science it becomes a guide to a balanced, happy life. In this respect, Hume stands outside the early modern mainstream in philosophy.

28 Millican links this criticism to his own goal, consisting mainly in the defense of Hume's commitment to empirical causal science without the capital (ontological) letter ‘C’. He argues that ‘constant conjunction is necessary to establish the causal connexions, but is also sufficient’ as a basis for such science, since the semantic understanding (counting on causation) is universal and thus justifies itself.

31 And similarly elsewhere; just at a glance: ‘it is impossible to make valid inferences about the characterization or even the existence of any mind-independent realities, any External World’.

Or, ‘Hume does not suppose that the necessity of believing in particular entities … constitutes a proof that there must be such entities … nor does he suppose that there is no reality … because the evidence that is available to us falls necessarily short of proving the existence of this particular kind of thing’.

38 Already since Montaigne, Pyrrhonism played an important role in the formation of ‘sceptical fideism’. Traditional proofs of God's existence were threatened by the indiscriminate sceptical scrutiny, and in order to ‘save’ religion, faith was transferred to the realm of heart; ‘only faith can embrace, with a lively certainty, the high mysteries of our religion’. Ibid., 3. The fideistic trend grew wider and continued via Charron, Foucher and Huet to Pascal or even Bayle. Bayle is known for his severe criticism of the dogmatic doctrines of the church and of its authoritarian institutions, for his appeal to tolerance. But Bayle found a private refuge (‘impenetrable shield against the arrows of the Pyrrhonists’) in fideism: ‘a man is therefore happily disposed toward faith when he knows how defective reason is.’ Here, Bayle echoes Montaigne; very similar phrases can be also found in Hume's Dialogues. Bayle's destructive scepticism showed Hume the need for a positive compensation but he no longer accepted the fideistic alternative to scepticism adopted by Bayle; Hume turned to a different area outside reason – the earthly life with its pleasures.

See also op. cit note 12, B 5, 47. Here, Kant argues that Hume had not established the strict necessity (and universality) of causation; custom, according to Kant, embodies only a subjective necessity and is not sufficient to ground rational thought (or the mere possibility of experience, for that matter).

56 This attitude was made easier by the fact that Hume was not trained or particularly interested in science. After all, he was under the influence of the specific intellectual atmosphere in Edinburgh where predominantly other things than natural science were discussed in the many famous clubs; the environment was more artistic and literary, interested in subjects of morals and religion and society. Hume turned to what he had at hand when he faced the sceptical crisis of reason, to moral sense and to common sense. How this particular environment fed into his greater openness to scepticism would be another intriguing issue to investigate further.

The whole citation goes like this: ‘… there are in England, in particular, many honest gentlemen, who being always employ'd in their domestic affairs, or amusing themselves in common recreations, have carried their thoughts very little beyond those objects, which are every day expos'd to their senses. And indeed, of such as these I pretend not to make philosophers, nor do I expect them either to be associates in these researches or auditors of these discoveries. They do well to keep themselves in their present situation; and instead of refining them into philosophers, I wish we cou'd communicate to our founders of systems a share of this gross earthly mixture, as an ingredient, which they commonly stand much in need of, and which wou'd serve to temper those fiery particles, of which they are compos'd’.
