It is especially in Spinoza that this deeper, universally human and ethical, indeed we can say religious, implication and ideal of the rigorously scientific spirit is present in all its noble intuition and aspiration, and that at the same time, alas, this deep truth is forced into a ruinously inappropriate method and formulation. For the original end of the entire quest, an end which is still emotionally dominant and which furnishes the hidden dialectic of the whole,--Man, his nobility and interior purification and beatitude,--has here, intellectually, become but a means; Man, in the real logic of this system, is, hopelessly and finally, but a wheel in the huge mechanism of that _natura naturata_ which Spinoza’s own richness and nobility of character transcends with potent inconsistency. And this very system, which is so nobly human and Christian in its ethical tone and in its demand of a Conversion of the whole man, in its requiring man to lose and sacrifice his petty self that he may gain his true self and become a genuine constituent of the Universe and Thought of God, is also the very one which, by its ruthless Naturalism and Determinism of Doctrine and its universally Mathematical and Quantitative form and method, logically eliminates all such qualitative differentiation and conversion as impossible and futile. The prima facie view of life as it presents itself to the clarifying, Scientific Intellect, namely the omnipresence of the determinist mechanism, has never been more impressively felt and pictured than by Spinoza; the dispositions and happiness of the purified, disinterested soul have rarely been experienced and described with more touching elevation and power. But there is no real transition, indeed no possibility of such, in his system, from that first aspect to this latter state; for that first aspect, that apparent determinism, is for his logic _not_ merely apparent or secondary, but the very truth of truths, the very core and end of things. And this bondage of mind to matter, this enslavement of the master to the servant, this narrow, doctrinaire intellectualism and determinism, is more hidden than cured in Leibniz, who, if he brings the immense improvement because enrichment of a keen sense and love of the Historical, loses, on the other hand, Spinoza’s grandly Conversional tone and temper. A cheerful, easy, eminently sane but quite inadequate bustle of manifold interests; a ready, pleasant optimism; an endless laboriousness of the reasoning faculty; all this, even though carried out on a scale unique since the days of Aristotle, is necessarily unequal to face and bear “the burthen of all this unintelligible world.”
