Whilst the ideas of Kant, by which he tried in his way to oppose Hume’s philosophy, have become within a short space of time the common possession of men’s minds, it was the fate of Reid’s ideas to find favour among only a restricted circle of friends. Moreover, they suffered decisive misunderstanding and distortion through the efforts of well-meaning disciples. This was because Kant’s work was a late fruit of an epoch of human development which had lasted for centuries and in his time began to draw to its close, while Reid’s work represents a seed of a new epoch yet to come. Here lies the reason also for his failure to develop his philosophy beyond the achievements contained in his first work. It is on the latter, therefore, that we shall chiefly draw for presenting Reid’s thoughts.
