THREE:The purely intellectual view of human nature, the definition of mind in terms of cognition, is one more fallacy from which Aristotle��s teaching, had it not fallen into neglect or contempt, might have guarded Spinoza. Nevertheless, his parallelism between passion and sensuous perception saves him from the worst extravagances of his Greek predecessors. For the senses, however much they might be maligned, never were nor could be altogether rejected; while the passions met with little mercy from Plato and with none from the Stoics, who considered them not only unnecessary but even unnatural. Spinoza more wisely sees in them assertions, however obscure and confused, of the will to be and grow which constitutes individual existence. And he sees that they can no more be removed by pointing out their evil consequences than sense-impressions can be abolished by proving their fallaciousness. On the other hand, when Spinoza speaks as if one emotion could only be conquered or expelled by another emotion, we must not allow his peculiar phraseology to conceal from us the purely intellectual character of his whole ethical system. What he really holds is that emotion can be416 overcome by reason or better knowledge, because it is itself an imperfect cognition. Point by point, an analogy��or something more than an analogy��is made out between the errors of sensuous perception joined to imagination, and the errors of our spontaneous efforts after happiness or self-realisation. Both are imposed on us from without, and neither can be got rid of by a simple act of volition. Both are affected by illusions of perspective: the nearer object of desire, like the nearer object of perception, assuming a disproportionate place in the field of view. In both, accidental contiguity is habitually confounded with causation; while in both the assignment of causes to effects, instead of being traced back through an infinite series of antecedents, stops short with the antecedent nearest to ourselves. If objects are classified according to their superficial resemblances or the usages of common language, so also are the desires sustained and intensified by imitation and rivalry. By parity of reasoning, moral education must be conducted on the same lines as intellectual education. First, it is shown how our individual existence, depending as it does on forces infinitely exceeding our own, is to be maintained. This is chiefly done by cultivating friendly relations with other men; probably, although Spinoza does not himself make the comparison, on the same principle as that observed in the mutual assistance and rectification of the senses, together with their preservation by means of verbal signs. The misleading passions are to be overcome by discovering their origin; by referring the pleasures and pains which produce them to the right causes; by calling in thought to redress the balance of imagination; by dividing the attention among an infinite number of causes; finally, by demonstrating the absolute necessity of whatever actions excite them, and classifying them according to their relations, in the same way that the phenomena of the material world are dealt with when subjected to scientific analysis.There still remained one last problem to solve, one point228 where the converging streams of ethical and metaphysical speculation met and mixed. Granted that knowledge is the soul��s highest energy, what is the object of this beatific vision? Granted that all particular energies co-operate for a common purpose, what is the end to which they are subordinated? Granted that dialectic leads us up through ascending gradations to one all-comprehensive idea, how is that idea to be defined? Plato only attempts to answer this last question by re-stating it under the form of an illustration. As the sun at once gives life to all Nature, and light to the eye by which Nature is perceived, so also the idea of Good is the cause of existence and of knowledge alike, but transcends them both as an absolute unity, of which we cannot even say that it is, for the distinction of subject and predicate would bring back relativity and plurality again. Here we seem to have the Socratic paradox reversed. Socrates identified virtue with knowledge, but, at the same time, entirely emptied the latter of its speculative content. Plato, inheriting the idea of knowledge in its artificially restricted significance, was irresistibly drawn back to the older philosophy whence it had been originally borrowed; then, just as his master had given an ethical application to science, so did he, travelling over the same ground in an opposite direction, extend the theory of ethics far beyond its legitimate range, until a principle which seemed to have no meaning, except in reference to human conduct, became the abstract bond of union between all reality and all thought.
