[paragraph continues] Thus the primary idea that the soul is real will automatically protect the soul from the cramping and warping pressure of dogmatism, and, while disposing it to welcome all sub-ideas which give it stimulus and guidance, will strengthen it to reject the teaching that is merely formal, and that does not reveal to it what is and has ever been its own.
This leads me to say again that, whatever spiritual ideas the thought of the West may borrow from whatever quarter, it must be able to assimilate these, if they are to rescue it from its present state of insolvency, and make them its own. I mean by this, first, that it must learn at last to recognize them as belonging to that inner life of the soul which it is the function of thought to interpret; and, next, that as they come to it--nominally from without, but really from within--it must meet them along its own line of approach, and give them the particular expression which is in keeping with its own criticism of life. For just as the individual soul, in the course of its development, should prove its individuality by universalizing itself in its own particular way, so if the soul of the West is to make the ideas which it borrows really productive, it must transform them by processes of its own till it has made them available, first for the special needs of the West, and then for the more general needs of Humanity. In this, and in no other way, will it be able to pay them back in due season, enriched and expanded by the use that it has made of them.
Four things, then, are needed if the bankruptcy of Western thought is to come to an end. In the
first place, the idea that the soul is ultimately real--an idea which the heart imperatively needs, but which the head is unable to supply--must be borrowed from some other source. In the second place, the idea must be accepted on its own evidence, and therefore without any shadow of reserve or doubt. This means that the source from which the idea is borrowed must be one in which, having always been regarded as demonstrably indemonstrable, it has the force and authority of an axiom,--not of a mere assumption, still less of a logical conclusion. In the third place, with this master idea the soul must borrow the subsidiary ideas by which it has been interpreted and otherwise supported in the land of its origin; but it must take care that these subsidiary ideas, while giving it stimulus and guidance, do not in any way cramp or deaden its life, or impede the free play of its thought and its desire. In the fourth place, it must make the ideas that it borrows its very own; for until it has done this it will not be able to trade with them to advantage; and it is only by trading with them to advantage that it can hope to pay them back, with the generous interest which is due for so timely a loan.
