We have seen something, but only one aspect, of this when discussing applied art; the relation is wider than this, since, for example, the amount of time, energy, money, and material available for artistic purposes is closely connected with material economic conditions. And, still further, there is the psychological or spiritual element, art satisfying human needs which are unsatisfied by other activities, supplementing, filling the gaps in our personal development. We cannot put art into a watertight compartment. The extent to which art appeals to an individual, and the particular way in which and the special medium through which artistic impulses find expression, will depend very largely upon biological and social factors, upon the materially ordered associations of the individual, his work, his health, everything that impinges upon his life. Further research will expose the fundamental reasons for this, but even now we realize that a love of dancing, of the theatre, of poetry, of sculpture is not a mere gift or genius or taste or predilection but also something which is fostered and directed by material environment. Confronted with this realization, we must regard art as an inseparable organic element in life, not as a superimposed culture which may or may not exist in any individual or take any form. And the corollary of this, as said before, is that, since artistic potentialities exist in all men according to their being and environment, the realm of art will present as large a variety of values, types, and manifestations as does our life itself. Yet all these manifestations are part of one. Good, bad, or indifferent, they represent the best, most suitable art that different men at any time are capable of appreciating or desirous of cultivating. This is the excuse for our plea for broadmindedness. _Each, pott 8vo, 2/6 net_ _Occasionally illustrated_ TO-DAY AND TO-MORROW This series of books, by some of the most distinguished English thinkers, scientists, philosophers, doctors, critics, and artists, was recognized on publication as a noteworthy event. Written from various points of view, one book frequently opposing the argument of another, they provide the reader with a stimulating survey of the most modern thought in many departments of life. Several volumes are devoted to the future trend of Civilization, conceived as a whole; while others deal with particular provinces, and cover the future of Woman, War, Population, Clothes, Wireless, Morals, Drama, Poetry, Art, Sex, Law, etc. It is interesting to see in these neat little volumes, issued at a low price, the revival of a form of literature, the Pamphlet, which has been in disuse for 200 years. _Published by_ KEGAN PAUL, TRENCH, TRUBNER & CO., LTD.
