Thomas Reid was one of the greatest thinkers of the Scottish Enlightenment. In his own time he was seen as the most able opponent of the scepticism of David Hume and the architect of 'Common Sense' philosophy. His ideas were immensely influential both in his native Scotland and abroad, and the last forty years have seen a marked revival of interest in his work. Reid published very little about religion and his notes from the lectures on natural theology that he regularly gave have not survived. This volume -- a companion to Thomas Reid: Selected Philosophical Writings (Imprint Academic, 2012) -- makes available material from Reid's autograph manuscripts, housed in the University of Aberdeen Library, and student notes of Reid's lectures, edited from original manuscripts in Aberdeen, Edinburgh and Glasgow. It includes an introductory essay by Nicholas Wolterstorff, a leading philosopher of religion and interpreter of Reid.
