Those, like the present writer, for whom the late Samuel Alexander unlocked doors to new realms of wisdom and delight, or who basked in the sunshine of encouragement and kindly advice he gave so readily to younger men, will understand with what alacrity this opportunity was seized of paying a small tribute to the memory of so unusual and attractive a personality. To resurrect the mind that has built of its own fabric a mansion so vast that its chambers have room for every fact of experience and every theory of science will always provide a happy and appropriate memorial to one whose main business in life was the disinterested speculation idolized by the Greeks as the worthiest employment to which the human spirit can devote its powers. My own share in this labour of love is small and limited in scope; I want to fill in one corner of the picture of Alexander's philosophical system, drawn by Professor Muirhead in the last number of Philosophy, by describing in some detail what he thought about Art and Beauty in their most important aspects and relations.
