Most writers on the emotions and on human conduct seem to be treating rather of matters outside nature than of natural phenomena following nature's g… - Benedictus de Spinoza

The second point to be considered is the method adopted by Spinoza for setting forth his philosophy; it is the demonstrative method of geometry as employed by Euclid, in which we find definitions, explanations, axioms, and theorems. Even Descartes made it his starting-point that philosophic propositions must be mathematically handled and proved, that they must have the very same evidence as mathematics. The mathematical method is considered superior to all others, on account of the nature of its evidence; and it is natural that independent knowledge in its re-awakening lighted first upon this form, of which it saw so brilliant an example. The mathematical method is, however, ill-adapted for speculative content, and finds its proper place only in the finite sciences of the understanding. In modern times Jacobi has asserted (Werke, Vol. IV. Section I. pp. 217-223) that all demonstration, all scientific knowledge leads back to Spinozism, which alone is a logical method of thought; and because it must lead thither, it is really of no service whatever, but immediate knowledge is what we must depend on. It may be conceded to Jacobi that the method of demonstration leads to Spinozism, if we understand thereby merely the method of knowledge belonging to the understanding. But the fact is that Spinoza is made a testing-point in modern philosophy, so that it may really be said: You are either a Spinozist or not a philosopher at all. This being so, the mathematical and demonstrative method of Spinoza would seem to be only a defect in the external form; but it is the fundamental defect of the whole position. In this method the nature of philosophic knowledge and the object thereof, are entirely misconceived, for mathematical knowledge and method are merely formal in character and consequently altogether unsuited for philosophy. Mathematical knowledge exhibits its proof on the existent object as such, not on the object as conceived; the Notion is lacking throughout; the content of Philosophy, however, is simply the Notion and that which is comprehended by the Notion. Therefore this Notion as the knowledge of the essence is simply one assumed, which falls within the philosophic subject; and this is what represents itself to be the method peculiar to Spinoza's philosophy.

I shall not attempt to speculate as to what Spinoza might have been if he had lived in our time. For me, in any case, one thing is not open to doubt: Spinoza would never have been an agent of the League of Nations. The second point that I wish to emphasize is that we do not agree to yield Spinoza to our enemies in any case. There is no reason at all for this. Spinoza was a great materialistic thinker, and in this respect he should be considered a predecessor of dialectical materialism. The contemporary proletariat is Spinoza's only genuine heir.

George Eliot herself had recognised Spinoza's importance some year before Arnold paid the philosopher this elaborate double-edged compliment. In a letter to Charles Bray in 1849 she wrote, diagnostically: "What is wanted in English is not a translation of Spinoza's works, but a true estimate of his life and system. After one has rendered his Latin faithfully into English, one feels that there is another yet more difficult process of translation for the reader to effect, and that the only mode of making Spinoza accessible to a larger number is to study his books, then shut them out and give an analysis." Since she began writing fiction only months after finishing work on the Ethics, it is plausible to consider Eliot's novels as attempting this larger project of Spinozan translation [...] But the detached voice speaking in this letter widens its import beyond the personal, for what animates Eliot here is an issue with a much broader horizon than private ambition: she is hinting at a more general correlation between Spinoza and contemporary British thought. Spinoza has become a crucial figure, she is insisting, one who speaks relevantly to the intellectual predicaments and debates of the mid-nineteenth century.
