88. The mind has no free will, but is determined by a cause, which itself is determined by some other, and so for ever. For the mind is but a mode of thinking and, therefore cannot be the free cause of its own actions. Nor has it any absolute faculty of loving, desiring, understanding; these being only metaphysical abstractions.[853] Will and understanding are one and the same thing; and volitions are only affirmations or negations, each of which belongs to the essence of the idea affirmed or denied.[854] In this there seems to be not only an extraordinary deviation from common language, but an absence of any meaning which, to my apprehension at least, is capable of being given to his words. Yet we have seen something of the same kind said by Malebranche; and it will also be found in a recently published work of Cudworth,[855] a writer certainly uninfluenced by either of these, so that it may be suspected of having some older authority.

[855] See Cudworth’s Treatise on Free will (1838), p. 20, where the will and understanding are purposely, and, I think, very erroneously confounded.
Spinosa’s theory of action and passion. 89. In the third part of this treatise, Spinosa comes to the consideration of the passions. Most who have written on moral subjects, he says, have rather treated man as something out of nature, or as a kind of imperium in imperio, than as part of the general order. They have conceived him to enjoy a power of disturbing that order by his own determination, and ascribed his weakness and inconstancy not to the necessary laws of the system, but to some strange defect in himself, which they cease not to lament, deride, or execrate. But the acts of mankind, and the passions from which they proceed, are in reality but links in the series, and proceed in harmony with the common laws of universal nature.
90. We are said to act when anything takes place within us, or without us, for which we are an adequate cause; that is, when it may be explained by means of our own nature alone. We are said to be acted upon, when anything takes place within us which cannot wholly be explained by our own nature. The affections of the body which increase or diminish its power of action, and the ideas of those affections, he denominates passions (affectus). Neither the body can determine the mind to thinking, nor can the mind determine the body to motion or rest. For all that takes place in body must be caused by God, considered under his attribute of extension, and all that takes place in mind must be caused by God under his attribute of thinking. The mind and body are but one thing, considered under different attributes; the order of action and passion in the body being the same in nature with that of action and passion in the mind. But men, though ignorant how far the natural powers of the body reach, ascribe its operations to the determination of the mind, veiling their ignorance in specious words. For if they alledge that the body cannot act without the mind, it may be answered that the mind cannot think till it is impelled by the body, nor are the volitions of the mind anything else than its appetites, which are modified by the body.
91. All things endeavoured to continue in their actual being; this endeavour being nothing else than their essence, which causes them to be, until some exterior cause destroys their being. The mind is conscious of its own endeavour to continue as it is, which is, in other words, the appetite that seeks self-preservation; what the mind is thus conscious of seeking, it judges to be good, and not inversely. Many things increase or diminish the power of action in the body, and all such things have a corresponding effect on the power of thinking in the mind. Thus, it undergoes many changes, and passes through different stages of more or less perfect power of thinking. Joy is the name of a passion, in which the mind passes to a greater perfection or power of thinking; grief, one in which it passes to a less. Spinosa, in the rest of this book, deduces all the passions from these two and from desire; but as the development of his theory is rather long, and we have already seen that its basis is not quite intelligible, it will be unnecessary to dwell longer upon the subject. His analysis of the passions may be compared with that of Hobbes.
Character of Spinosism. 92. Such is the metaphysical theory of Spinosa, in as concise a form as I found myself able to derive it from his Ethics. It is a remarkable proof, and his moral system will furnish another, how an undeviating adherence to strict reasoning may lead a man of great acuteness and sincerity from the paths of truth. Spinosa was truly, what Voltaire has with rather less justice called Clarke, a reasoning machine. A few leading theorems, too hastily taken up as axiomatic, were sufficient to make him sacrifice, with no compromise or hesitation, not only every principle of religion and moral right, but the clear intuitive notions of common sense. If there are two axioms more indisputable than any others, they are that ourselves exist, and that our existence is exclusive of any other being. Yet both these are lost in the pantheism of Spinosa, as they had always been in that delusive reverie of the imagination. In asserting that the being of the human mind consists in the idea of an existing thing presented to it, this subtle metaphysician fell into the error of the school which he most disdained, as deriving all knowledge from perception, that of the Aristotelians. And, extending this confusion of consciousness with perception to the infinite substance, or substratum of particular ideas, he was led to deny it the self, or conscious personality, without which the name of Deity can only be given in a sense deceptive of the careless reader, and inconsistent with the use of language. It was an equally legitimate consequence of his original sophism to deny all moral agency, in the sense usually received, to the human mind, and even, as we have seen, to confound action and passion themselves, in all but name, as mere phenomena in the eternal sequence of things.
93. It was one great error of Spinosa to entertain too arrogant a notion of the human faculties, in which, by dint of his own subtle demonstrations, he pretended to show a capacity of adequately comprehending the nature of what he denominated God. And this was accompanied by a rigid dogmatism, no one proposition being stated with hesitation, by a disregard of experience, at least as the basis of reasoning, and by an uniform preference of the synthetic method. Most of those, he says, who have turned their minds to those subjects have fallen into error, because they have not begun with the contemplation of the divine nature, which both in itself and in order of knowledge is first, but with sensible things, which ought to have been last. Hence, he seems to have reckoned Bacon, and even Descartes, mistaken in their methods.
94. All pantheism must have originated in overstraining the infinity of the divine attributes till the moral part of religion was annihilated in its metaphysics. It was the corruption, or rather, if we may venture the phrase, the suicide of theism; nor could this strange theory have arisen, except where we know it did arise, among those who had elevated their conceptions above the vulgar polytheism that surrounded them to a sense of the unity of the Divine nature.
