Although, however, we may justly quarrel with such unlooked-for difficulties, the important question, after all, is not of their obscurity but of their truth. Many things in all the sciences are obscure to an unpractised understanding, which are true enough and clear enough to people acquainted with the subjects, and may be fairly laid as foundations of a scientific system, although rudimentary students must be contented to accept them upon faith. Of course it is entirely competent to Spinoza, or to any one, to define the terms which he intends to use just as he pleases, provided it be understood that any conclusions which he derives out of them apply only to the ideas so defined, and not to any supposed object existing which corresponds with them. Euclid defines his triangles and circles, and discovers that to figures so described certain properties previously unknown may be proved to belong; but as in nature there are no such things as triangles and circles exactly answering the definition, his conclusions, as applied to actually existing objects, are either not true at all or only proximately so. Whether it be possible to bridge over the gulf between existing things and the abstract conception of them, as Spinoza attempts to do, we shall presently see. It is a royal road to certainty if it be a practicable one, but we cannot say that we ever met any one who could say honestly Spinoza had convinced him; and power of demonstration, like all other powers, can be judged only by its effects. Does it prove? does it produce conviction? If not, it is nothing. We need not detain our readers among these abstractions. The real power of Spinozism does not lie so remote from ordinary appreciation, or we should long ago have heard the last of it. Like all other systems which have attracted followers, it addresses itself not to the logical intellect but to the imagination, which it affects to set aside. We refuse to submit to the demonstrations by which it thrusts itself upon our reception, but regarding it as a whole, as an attempt to explain the nature of the world, of which we are a part, we can still ask ourselves how far the attempt is successful. Some account of these things we know that there must be, and the curiosity which asks the question regards itself, of course, as competent in some degree to judge of the answer to it. Before proceeding, however, to regard this philosophy in the aspect in which it is really powerful, we must clear our way through the fallacy of the method.
The system is evolved in a series of theorems in severely demonstrative order out of the definitions and axioms which we have translated. To propositions 1—6 we have nothing to object; they will not, probably, convey any very clear ideas, but they are so far purely abstract, and seem to follow (as far as we can speak of "following," in such subjects), by fair reasoning. "Substance is prior in nature to its affections." "Substances with different attributes have nothing in common," and therefore "one cannot be the cause of the other." "Things really distinct are distinguished by difference either of attribute or mode (there being nothing else by which they can be distinguished), and therefore, because things modally distinguished do not qua substance differ from one another, there cannot be more than one substance of the same attribute; and therefore (let us remind our readers that we are among what Spinoza calls notiones simplicissimas), since there cannot be two substances of the same attribute and substances of different attributes cannot be the cause one of the other, it follows that no substances can be produced by another substance."
The existence of substance, he then concludes, is involved in the nature of the thing itself. Substance exists. It does and must. We ask, why? and we are answered, because there is nothing capable of producing it, and therefore it is self-caused; i.e. by the first definition the essence of it implies existence as part of the idea. It is astonishing that Spinoza should not have seen that he assumes the fact that substance does exist in order to prove that it must. If it cannot be produced and exists, then, of course, it exists in virtue of its own nature. But supposing it does not exist, supposing it is all a delusion, the proof falls to pieces, unless we fall back on the facts of experience, on the obscure and unscientific certainty that the thing which we call the world, and the personalities which we call ourselves, are a real substantial something. Conscious of the infirmity of his demonstration, he winds round it and round it, adding proof to proof, but never escaping the same vicious circle: substance exists because it exists, and the ultimate experience of existence, so far from being of that clear kind which can be accepted as an axiom, is the most confused of all our sensations. What is existence? and what is that something which we say exists? Things—essences— existences; these are but the vague names with which faculties, constructed only to deal with conditional phenomena, disguise their incapacity. The world in the Hindoo legend rested upon the back of the tortoise. It was a step between the world and nothingness, and served to cheat the imagination with ideas of a fictitious resting-place.
"If any one affirms," says Spinoza, "that he has a clear, distinct—that is to say, a true idea of substance, but that nevertheless he is uncertain whether any such substance exist, it is the same as if he were to affirm that he had a true idea, but yet was uncertain whether it was not false. Or if he says that substance can be created, it is like saying that a false idea can become a true idea—as absurd a thing as it is possible to conceive; and therefore the existence of substance, as well as the essence of it, must be acknowledged as an eternal verity."
It is again the same story. He speaks of a clear idea of substance; but he has not proved that such an idea is within the compass of the mind. A man's own notion that he sees clearly, is no proof that he really sees clearly; and the distinctness of a definition in itself is no evidence that it corresponds adequately with the object of it. No doubt a man who professes to have an idea of substance as an existing thing, cannot doubt, as long as he has it, that substance so exists. It is merely to say that as long as a man is certain of this or that fact, he has no doubt of it. But neither his certainty nor Spinoza's will be of any use to a man who has no such idea, and who cannot recognize the lawfulness of the method by which it is arrived at.
From the self-existing substance it is a short step to the existence of God. After a few more propositions following one another with the same kind of coherence, we arrive successively at the conclusions that there is but one substance, that this substance being necessarily existent, it is also infinite, and that it is therefore identical with the Being who had been previously defined as the "Ens absolute perfectum," consisting of infinite "attributes, each of which expresses His eternal and infinite essence." Demonstrations of this kind were the characteristics of the period. Des Cartes had set the example of constructing them, and was followed by Cudworth, Clerke, Berkeley, and many others besides Spinoza. The inconclusiveness of their reasoning may perhaps be observed most readily in the strangely opposite conceptions formed by all these writers of the nature of that Being whose existence they nevertheless agreed, by the same method, to gather each out of their ideas. It is important, however, to examine it carefully, for it is the very key-stone of the Pantheistic system. As stated by Des Cartes, the argument stands something as follows:—God is an all-perfect Being,—perfection is the idea which we form of him: existence is a mode of perfection, and therefore God exists. The sophism we are told is only apparent; existence is part of the idea; it is as much involved in it, as the equality of all lines drawn from the centre to the circumference of a circle is involved in the idea of a circle, and a non-existent all-perfect Being is as inconceivable as a quadrilateral triangle. It is sometimes answered that in this way we may prove the existence of anything, —Titans, Chimaeras, or the Olympian Gods; we have but to define them as existing, and the proof is complete. But in this objection there is really nothing of weight; none of these beings are by hypothesis absolutely perfect, and, therefore, of their existence we can conclude nothing. With greater justice, however, we may say, that of such terms as perfection and existence we know too little to speculate in this way. Existence may be an imperfection for all we can tell; we know nothing about the matter. Such arguments are but endless petilianes principii, like the self-devouring serpent resolving themselves into nothing. We wander round and round them, in the hope of finding some tangible point at which we can seize their meaning; but we are presented everywhere with the same impracticable surface, from which our grasp glides off ineffectual.
The idea, however, lying at the bottom of the conviction, which obviously Spinoza felt upon the matter, is stated with sufficient distinctness in one of his letters. "Nothing is more clear," he writes to his pupil De Vries, "than that, on the one hand, everything which exists is conceived by or under some attribute or other; that the more reality, therefore, a being or thing has, the more attributes must be assigned to it;" "and conversely," (and this he calls his argumentum palmarium in proof of the existence of God,) "the more attributes I assign to a thing, the more I am forced to conceive it as existing." Arrange the argument how we please, we shall never get it into a form clearer than this:—The more perfect a thing is, the more it must exist (as if existence could admit of more or less); and therefore the all-perfect Being must exist absolutely. There is no flaw, we are told, in the reasoning; and if we are not convinced, it is solely from the confused habits of our own minds.
It may seem to some persons that all arguments are good when on the right side, and that it is a gratuitous impertinence to quarrel with the proofs of a conclusion which it is so desirable that all should receive. As yet, however, we are but inadequately acquainted with the idea attached by Spinoza to the word perfection, and if we commit ourselves to this logic, it may lead us out to some unexpected consequences. Obviously all such reasonings presume, as a first condition, that we men possess faculties capable of dealing with absolute ideas; that we can understand the nature of things external to ourselves as they really are in their absolute relation to one another, independent of our own conception. The question immediately before us is one which can never be determined. The truth which is to be proved is one which we already believe; and if, as we believe also, our conviction of God's existence is, like that of our own existence, intuitive and immediate, the grounds of it can never adequately be analysed; we cannot say exactly what they are, and therefore we cannot say what they are not; whatever we receive intuitively, we receive without proof; and stated as a naked proposition, it must involve necessarily a petitio principii. We have a right, however, to object at once to an argument in which the conclusion is more obvious than the premises; and if it lead on to other consequences which we disapprove in themselves, we reject it without difficulty or hesitation. We ourselves believe that God is, because we experience the control of a "power" which is stronger than we; and our instincts teach us so much of the nature of that power as our own relation to it requires us to know. God is the being to whom our obedience is due; and the perfections which we attribute to Him are those moral perfections which are the proper object of our reverence. Strange to say, the perfections of Spinoza, which appear so clear to him, are without any moral character whatever; and for men to speak of the justice of God, he tells us, is but to see in Him a reflection of themselves: as if a triangle were to conceive of Him as eminenter triangularis, or a circle to give Him the property of circularity.
Having arrived, however, at existence, we soon find ourselves among ideas, which at least are intelligible, if the character of them is as far removed as before from the circle of ordinary thought. Nothing exists except substance, the attributes under which substance is ex expressed, and the modes or affections of those attributes. There is but one substance self-existent, eternal, necessary, and that is the absolutely Infinite all-perfect Being. Substance cannot produce substance; and, therefore, there is no such thing as creation, and everything which exists, is either an attribute of Him, or an affection of some attribute of Him, modified in this manner or in that. Beyond Him there is nothing, and nothing like Him or equal to Him; He therefore alone in Himself is absolutely free, uninfiuenced by anything, for nothing is except Himself; and from Him and from His supreme power, essence, intelligence (for all these words mean the same thing) all things have necessarily flowed, and will and must flow on for ever, in the same manner as from the nature of a triangle it follows, and has followed, and will follow from eternity to eternity, that the angles of it are equal to two right angles. It would seem as if the analogy were but an artificial play upon words, and that it was only metaphorically that in mathematical demonstration we speak of one thing as following from another. The properties of a curve or a triangle are what they are at all times, and the sequence is merely in the order in which they are successively known to ourselves. But according to Spinoza, this is the only true sequence; and what we call the universe, and all the series of incidents upon it, are involved formally and mathematically in the definition of God.
Each attribute is infinite suo genere; and it is time that we should know distinctly the meaning which Spinoza attaches to that important word. Out of the infinite number of the attributes of God two only are known to us—"extension," and "thought," or "mind." Duration, even though it be without beginning or end, is not an attribute; it is not even a real thing. It has no relation to being conceived mathematically, in the same way as it would be absurd to speak of circles or triangles as any older to-day than they were at the beginning of the world. These and everything of the same kind are conceived, as Spinoza rightly says, sub quadam specie aeternitatis. But extension, or substance extended, and thought, or substance perceiving, are real, absolute, and objective. We must not confound extension with body, for though body be a mode of extension, there is extension which is not body, and it is infinite because we cannot conceive it to be limited except by itself—-or, in other words, to be limited at all. And as it is with extension, so it is with mind, which is also infinite with the infinity of its object. Thus there is no such thing as creation, and no beginning or end. All things of which our faculties are cognizant under one or other of these attributes are produced from God, and in Him they have their being, and without Him they would cease to be.
