Looking backward for the generative source of that creative power of thought in him, from his own mysterious intellectual being to its first cause, he still reflected, as one can but do, the enlarged pattern of himself into the vague region of hypothesis. In this way, some, at all events, would have explained his mental process. To him that process was nothing less than the apprehension, the revelation, of the greatest and most real of ideas--the true substance of all things. He, too, with his vividly-coloured existence, with this picturesque and sensuous world of Dutch art and Dutch reality all around that would fain have made him the prisoner of its colours, its genial warmth, its struggle for life, its selfish and crafty love, was but a transient perturbation of the one absolute mind; of which, indeed, all finite things whatever, time itself, the most durable achievements of nature and man, and all that seems most like independent energy, are no more than petty accidents or affections. Theorem and corollary! Thus they stood: "There can be only one substance: (corollary) it is the greatest of errors to think that the non-existent, the world of finite things seen and felt, really is: (theorem): for, whatever is, is but in that: (practical corollary): one's wisdom, therefore, consists in hastening, so far as may be, the action of those forces which tend to the restoration of equilibrium, the calm surface of the absolute, untroubled mind, to tabula rasa, by the extinction in one's self of all that is but correlative to the finite illusion--by the suppression of ourselves." In the loneliness which was gathering round him, and, oddly enough, as a somewhat surprising thing, he wondered whether there were, or had been, others possessed of like thoughts, ready to welcome any such as his veritable compatriots. And in fact he became aware just then, in readings difficult indeed, but which from their all-absorbing interest seemed almost like an illicit pleasure, a sense of kinship with certain older minds. The study of many an earlier adventurous theorist satisfied his curiosity as the record of daring physical adventure, for instance, might satisfy the curiosity of the healthy. It was a tradition--a constant tradition--that daring thought of his; an echo, or haunting recurrent voice of the human soul itself, and as such sealed with natural truth, which certain minds would not fail to heed; discerning also, if they were really loyal to themselves, its practical conclusion.--The one alone is: and all things beside are but its passing affections, which have no necessary or proper right to be.
