concerned himself. They all lie outside the demonstrations of Ferrier, in which he unfolds his theory in forms of artistic beauty and easy grace, which make him the most picturesque figure in the succession of Scottish philosophers. Yet Brown and Ferrier in the end helped on the expansion of Reid.

The idea of continuous physical evolution of external nature and of man, promulgated biologically by Darwin, and by Mr. Herbert Spencer as the all-comprehensive generalised law of a universe that was supposed to be the outcome of unknowable Power, has become a popular creed within the last forty years. Simultaneously, methods of development akin to Hegel were introduced by Dr. Hutcheson Stirling in his Secret of Hegel, and afterwards in Glasgow by Dr. Caird, who adorned Reid’s chair for nearly thirty years—methods for making explicit latent Divine Reason as what explains and sustains the universe.
