Thomas Reid’s theory of perception is presented in two separate works published more than twenty years apart. For the most part scholars have agreed with D.D. Todd’s view that “there is very little that in any rich sense can be called development in Reid’s philosophy.” The general view seems to be that the two works differ in emphasis and presentation rather than in philosophical position. Reid himself lends support to this interpretation by remarking to former students that in the Intellectual (...) Powers they will “recognise the doctrine which they heard, some of them thirty years ago”. (shrink)
