Radical skepticism endorses the extreme claim that large swaths of our ordinary beliefs, such as those produced by perception or memory, are irrational. The best arguments for such skepticism are, in their essentials, as familiar as a popular science fiction movie and yet even seasoned epistemologists continue to find them strangely seductive. Moreover, although most contemporary philosophers dismiss radical skepticism, they cannot agree on how best to respond to the challenge it presents. In the tradition of the 18th century Scottish (...) philosopher, Thomas Reid, Radical Skepticism and Epistemic Intuition joins this discussion by taking up four main tasks. First, it identifies the strongest arguments for radical skepticism, namely, underdetermination arguments, which emphasize the gap between our evidence and our ordinary beliefs based on that evidence. Second, it rejects all inferential or argument-based responses to radical skepticism, which aim to lay out good noncircular reasoning from the evidence on which we base our ordinary beliefs to the conclusion that those beliefs are probably true. Third, it develops a commonsense noninferential response to radical skepticism with two distinctive features: it consciously and extensively relies on epistemic intuitions, which are seemings about epistemic goods, such as knowledge and rationality, and it can be endorsed without difficulty by both internalists and externalists in epistemology. Fourth, and finally, it defends this commonsense epistemic-intuition-based response to radical skepticism against a variety of objections, including those connected with underdetermination worries, epistemic circularity, disagreement problems, experimental philosophy, and concerns about whether it engages skepticism in a sufficiently serious way.

This is Thomas Reid's greatest work. It covers far more philosophical ground than the earlier, more popular Inquiry. The Intellectual Powers and its companion volume, Essays on the Active Powers of Man, constitute the fullest, most original presentation of the philosophy of Common Sense. In the process, Reid provides acutely critical discussions of an impressive array of thinkers but especially of David Hume. In Reid's eyes, Hume had driven a deep tendency in modern philosophy to its ultimate conclusions by creating (...) a phantom-world of so-called 'ideas' that sprang from objects of observation; the self was a conglomeration of perceived ideas; and the will as the source of action was nothing but the balance of passionate impulses.Reid's Common Sense philosophy answers these problems by suggesting that sceptics, such as Hume, unavoidably affirm what they purport to deny, namely the existence of a stable external world, of other minds, of the continuity of their own minds, and of their own and other people's ability to ascribe and accept responsibility for actions. We can understand all of this by proper empirical observation and philosophical analysis of the activity of the mind. Reid's major positive contribution to philosophy is a detailed account of the various innate powers of the mind. While particularly influential in the first half of the nineteenth century, Reid's work has retained a significant role in philosophy, not least in recent years. At the same time, his role in the Scottish Enlightenment is becoming much better understood.This is the only properly established text.
