 and disingenuousness, becomes intolerable, and provokes a general revolt in which too often the truth of it is buried with the error in a common oblivion.

If idealism is intrenched in the very structure of human reason, empiricism represents all those energies of the external universe which, as Spinoza says, must infinitely exceed the energies of man. If meditation breeds science, wisdom comes by disillusion, even on the subject of science itself. Docility to the facts makes the sanity of science. Reason is only half grown and not really distinguishable from imagination so long as she cannot check and recast her own processes wherever they render the moulds of thought unfit for their subject-matter. Docility is, as we have seen, the deepest condition of reason’s existence; for if a form of mental synthesis were by chance developed which was incapable of appropriating the data of sense, these data could not be remembered or introduced at all into a growing and cumulative experience. Sensations would leave no memorial; while logical thoughts would play idly, like so many parasites in the mind, and ultimately languish and die of inanition. To be nourished and employed, intelligence must have developed such structure and habits as will enable it to assimilate what food comes in its way; so that the persistence of any intellectual habit is a proof that it has some applicability, however partial, to the facts of sentience.
