thoughts fixed upon the inanity of all this in comparison with the unthinkable truth, with the undivided and unimaginable reality. Everything, says the mystic, is nothing, in comparison with the One. This confusion, the logical contradiction of which we have just seen, may, for lack of a more specific word, be called mysticism. It consists in the surrender of a category of thought on account of the discovery of its relativity. If I saw or reasoned or judged by such a category, I should be seeing, reasoning, or judging in a specific manner, in a manner conditioned by my finite nature. But the specific and the finite, I feel, are odious; let me therefore aspire to see, reason and judge in no specific or finite manner—that is, not to see, reason or judge at all. So I shall be like the Infinite, nay I shall become one with the Infinite and (marvellous thought!) one with the One. The ideal of mysticism is accordingly exactly contrary to the ideal of reason; instead of perfecting human nature it seeks to abolish it; instead of building a better world, it would undermine the foundations even of the world we have built already; instead of developing our mind to greater scope and precision, it would return to the condition of protoplasm—to the blessed consciousness of an Unutterable Reality. In the primary stages, of course, mysticism does not venture to abolish all our ideas, or to renounce all our categories of thought. Thus many Christian mystics have still clung, out of respect for authority, to traditional theology, and many philosophical mystics have made some room for life and science in the post-scripts which they, like Parmenides, have appended to the blank monism of their systems. But such concessions or hesitations are inconsistent with the mystical spirit which will never be satisfied, if fully developed and fearless, with anything short of Absolute Nothing. For the very reason, however, that mysticism is a tendency to obliterate distinctions, a partial mysticism often serves to bring out with wonderful intensity those underlying strata of experience which it has not yet decomposed. The razing of the edifice of reason may sometimes discover its foundations. Or the disappearance of one department of activity may throw the mind with greater energy into another. So Spinoza, who combined mysticism in morals with rationalism in science, can bring out the unqualified naturalism of his system with a purity and impressiveness impossible to men who still retain an ideal world, and seek to direct endeavour as well as to describe it. Having renounced all ideal categories, Spinoza has only the material categories left
