Amongst the apparent enigmas of life, amongst the seemingly most radical and abiding of interior antinomies and conflicts experienced by the human race and by individuals, there is one which everything tends to make us feel and see with an ever-increasing keenness and clearness. More and more we want a strong and interior, a lasting yet voluntary bond of union between our own successive states of mind, and between what is abiding in ourselves and what is permanent within our fellow-men; and more and more we seem to see that mere Reasoning, Logic, Abstraction,—all that appears as the necessary instrument and expression of the Universal and Abiding,—does not move or win the will, either in ourselves or in others; and that what does thus move and win it, is Instinct, Intuition, Feeling, the Concrete and Contingent, all that seems to be of its very nature individual and evanescent.
