Outside this possibility the imagination can see nothing but grounds for pessimism. It needs but little effort of foresight to realize that without some totally revolutionary change in man’s attitude towards the mind, even his very tenure of the earth may come to be threatened. Recent developments in the study of disease have shown us how blind and fumbling have been our efforts against the attacks of our immemorial enemies the unicellular organisms. When we remember their capacities for variation and our fixity, we can see that for the race effectually and permanently to guard itself against even this one danger are necessary that fineness and complexity of organization, that rendering available of the utmost capacity of its members, against which the face of society seems at present to be so steadily set. We see man to-day, instead of the frank and courageous recognition of his status, the docile attention to his biological history, the determination to let nothing stand in the way of the security and permanence of his future, which alone can establish the safety and happiness of the race, substituting blind confidence in his destiny, unclouded faith in the essentially respectful attitude of the universe towards his moral code, and a belief no less firm that his traditions and laws and institutions necessarily contain permanent qualities of reality. Living as he does in a world where outside his race no allowances are made for infirmity, and where figments however beautiful never become facts, it needs but little imagination to see how great are the probabilities that after all man will prove but one more of Nature’s failures, ignominously to be swept from her work-table to make way for another venture of her tireless curiosity and patience. 1909. {66} SPECULATIONS UPON THE HUMAN MIND IN 1915 MAN’S PLACE IN NATURE AND NATURE’S PLACE IN MAN As the nineteenth century draws away into the past and it is possible to get a comprehensive view of the intellectual legacies it has left to its successor, certain of its ideas stand out from the general mass by reason of the greatness of their scale and scope. Ideas of the first order of magnitude are from their very greatness capable of full appreciation only in a comparatively distant view. However much they have been admired and studied by contemporary thought, it is with the passage of time only that all their proportions come gradually into focus. The readjustments of thought as to what used to be called man’s place in nature, which were so characteristic a work of the latter half of the nineteenth century, embodied an idea of this imperial type which, fruitful as it has proved, has even now yielded far less than its full harvest of truth.
