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.

(Originally published in _Reid Studies_ 4 (2000-01): 35-51.) Reid and Berkeley disagreed over whether we directly perceive objects located outside of us in a surrounding space, commonly revealed by both vision and touch. Berkeley considered a successful account of erect vision to be crucial for deciding this dispute, at one point calling it ‘the principal point in the whole optic theory.’ Reid's critique of Berkeley's position on this topic is very brief, and appears to miss Berkeley's point. I argue that (...) there is more to Reid's response to Berkeley than at first meets the eye. Reid's rival account of erect vision draws on evidence that makes a compelling case for the position that we see the same space that we touch. (shrink)

This paper examines Berkeley's attitude toward our perception of spatial relations on the two- dimensional visual field. This is a topic on which there has been some controversy. Historians of visual theory have tended to suppose that Berkeley took "all" spatial relations to be derived in the way our knowledge of depth is: from association of more primitive sensations which are themselves in no way spatial. But many philosophers commenting on Berkeley have supposed that he takes our awareness of two- (...) dimensional visual layout to be directly perceived. I argue that Berkeley's position on this issue is deeply ambivalent and that neither alternative sits well with the rest of his philosophy. (shrink)
