The pervasiveness of Protestant natural law in the early modern period and its significance in the Scottish Enlightenment have long been recognised. This book reveals that Thomas Reid (1710-1796) - the great contemporary of David Hume and Adam Smith - also worked in this tradition. When Reid succeeded Adam Smith as professor of moral philosophy in Glasgow in 1764, he taught a course covering pneumatology, practical ethics, and politics. This section on practical ethics took its starting point from the system of natural law and rights published by Francis Hutcheson. Knud Haakonssen has reconstructed it here for the first time from Reid's manuscript lectures and papers, and it provides a considerable addition to our understanding not only of Reid but of the thought of the Scottish Enlightenment and of the education system of the time. The present work is a revised version of a work first published by Princeton University Press in 1990 which has long been out of print.
The Reverend Thomas Reid FRSE, a religiously trained Scottish philosopher and a contemporary of David Hume, was the founder of the Scottish School of Common Sense and played an integral role in the Scottish Enlightenment. The early part of his life was spent in Aberdeen, Scotland, where he created the 'Wise Club' (a literary-philosophical association) and graduated from the University of Aberdeen. He was given a professorship at King's College, Aberdeen in 1752, where he wrote An Inquiry Into the Human Mind on the Principles of Common Sense (published in 1764). Shortly afterwards he was given the prestigious Professorship of Moral Philosophy at the University of Glasgow when he was called to replace Adam Smith. He resigned from this position in 1781.
Reid believed that common sense (in a special philosophical sense of sensus communis) is, or at least should be, at the foundation of all philosophical inquiry. He disagreed with Hume, who asserted that we can never know what an external world consists of as our knowledge is limited to the ideas in the mind, and George Berkeley, who asserted that the external world is merely ideas in the mind. By contrast, Reid claimed that the foundations upon which our sensus communis are built justify our belief that there is an external world.
