We do not know that we can add anything to this explanation; the difficulty lies in the audacious sweep of the speculation itself; we will, however, attempt an illustration, although we fear it will be to illustrate obscurum per obscurius. Let A B C D be four out of the Infinite number of the Divine attributes. A the attribute of mind; B the attribute of extension; C and D other attributes, the nature of which is not known to us. Now, A, as the attribute of mind, is that which perceives all which takes place under B C and D, but it is only as it exists in God that it forms the universal consciousness of all attributes at once. In its modifications it is combined separately with the modifications of each, constituting in combination with the modes of each attribute a separate being. As forming the mind of B, A perceives what takes place in B, but not what takes place in C or D. Combined with B, it forms the soul of the human body, and generally the soul of all modifications of extended substance; combined with C, it forms the soul of some other analogous being; combined with D, again of another; but the combinations are only in pairs, in which A is constant. A and B make one being, A and C another, A and D a third; but B will not combine with C, nor C with D; each attribute being, as it were, conscious only of itself. And therefore, although to those modifications of mind and extension which we call ourselves, there are corresponding modifications under C and D, and generally under each of the Infinite attributes of God, each of ourselves being in a sense Infinite—nevertheless, we neither have nor can have any knowledge of ourselves in this Infinite aspect; our actual consciousness being limited to the phenomena of sensible experience.

English readers, however, are likely to care little for all this; they will look to the general theory, and judge of it as its aspect affects them. And first, perhaps, they will be tempted to throw aside as absurd the notion that their bodies go through the many operations which they experience them to do, undirected by their minds. It is a thing, they may say, at once preposterous and incredible. It is, however, less absurd than it seems; and, though we could not persuade ourselves to believe it, absurd in the sense of having nothing to be said for it, it certainly is not. It is far easier, for instance, to imagine the human body capable by its own virtue, and by the laws of material organisation, of building a house, than of thinking; and yet men are allowed to say that the body thinks, without being regarded as candidates for a lunatic asylum. We see the seed shoot up into stem and leaf and throw out flowers; we observe it fulfilling processes of chemistry more subtle than were ever executed in Liebig's laboratory, and producing structures more cunning than man can imitate. The bird builds her nest, the spider shapes out its delicate web, and stretches it in the path of his prey; directed not by calculating thought, as we conceive ourselves to be, but by some motive influence, our ignorance of the nature of which we disguise from ourselves, and call it instinct, but which we believe at least to be some property residing in the organisation. We are not to suppose that the human body, the most complex of all material structures, has slighter powers in it than the bodies of a seed, a bird, or an insect. Let us listen to Spinoza himself:—

There can be no doubt (he says) that this hypothesis is true; but unless I can prove it from experience, men will not, I fear, be induced even to reflect upon it calmly, so persuaded are they that it is by the mind only that their bodies are set in motion. And yet what body can or cannot do no one has yet determined; body, i.e., by the law of its own nature, and without assistance from mind. No one has so probed the human frame as to have detected all its functions and exhausted the list of them; there are powers exhibited by animals far exceeding human sagacity; and, again, feats are performed by somnambulists on which in the waking state the same persons would never venture—itself a proof that body is able to accomplish what mind can only admire. Men say that mind moves body, but how it moves it they cannot tell, or what degree of motion it can impart to it; so that, in fact, they do not know what they say, and are only confessing their own ignorance in specious language. They will answer me, that whether or not they understand how it can be, yet that they are assured by plain experience that unless mind could perceive, body would be altogether inactive; they know that it depends on the mind whether the tongue speaks or is silent. But do they not equally experience that if their bodies are paralysed their minds cannot think?—that if their bodies are asleep their minds are without power?—that their minds are not at all times equally able to exert themselves even on the same subject, but depend on the state of their bodies? And as for experience proving that the members of the body can be controlled by the mind, I fear experience proves very much the reverse. But it is absurd (they rejoin) to attempt to explain from the mere laws of body such things as pictures, or palaces, or works of art; the body could not build a church unless mind directed it. I have shown, however, that we do not yet know what body can or cannot do, or what would naturally follow from the structure of it; that we experience in the feats of somnambulists something which antecedently to that experience would have seemed incredible. This fabric of the human body exceeds infinitely any contrivance of human skill, and an infinity of things, as I have already proved, ought to follow from it.

We are not concerned to answer this reasoning, although if the matter were one the debating of which could be of any profit, it would undoubtedly have its weight, and would require to be patiently considered. Life is too serious, however, to be wasted with impunity over speculations in which certainty is impossible, and in which we are trifling with what is inscrutable.

Objections of a far graver kind were anticipated by Spinoza himself, when he went on to gather out of his philosophy 'that the mind of man being part of the Infinite intelligence, when we say that such a mind perceives this thing or that, we are, in fact, saying that God perceives it, not as he is Infinite, but as he is represented by the nature of this or that idea; and similarly, when we say that a man does this or that action, we say that God does it, not quâ he is Infinite, but quâ he is expressed in that man's nature.' 'Here,' he says, 'many readers will no doubt hesitate, and many difficulties will occur to them in the way of such a supposition.'

We confess that we ourselves are among these hesitating readers. As long as the Being whom Spinoza so freely names remains surrounded with the associations which in this country we bring with us out of our childhood, not all the logic in the world would make us listen to language such as this. It is not so—we know it, and that is enough. We are well aware of the phalanx of difficulties which lie about our theistic conceptions. They are quite enough, if religion depended on speculative consistency, and not in obedience of life, to perplex and terrify us. What are we? what is anything? If it be not divine—what is it then? If created—out of what is it created? and how created—and why? These questions, and others far more momentous which we do not enter upon here, may be asked and cannot be answered; but we cannot any the more consent to Spinoza on the ground that he alone consistently provides an answer; because, as we have said again and again, we do not care to have them answered at all. Conscience is the single tribunal to which we choose to be referred, and conscience declares imperatively that what he says is not true. It is painful to speak of all this, and as far as possible we designedly avoid it. Pantheism is not Atheism, but the Infinite Positive and the Infinite Negative are not so remote from one another in their practical bearings; only let us remember that we are far indeed from the truth if we think that God to Spinoza was nothing else but that world which we experience. It is but one of infinite expressions of him—a conception which makes us giddy in the effort to realise it.

We have arrived at last at the outwork of the whole matter in its bearings upon life and human duty. It was in the search after this last, that Spinoza, as we said, travelled over so strange a country, and we now expect his conclusions. To discover the true good of man, to direct his actions to such ends as will secure to him real and lasting felicity, and, by a comparison of his powers with the objects offered to them, to ascertain how far they are capable of arriving at these objects, and by what means they can best be trained towards them—is the aim which Spinoza assigns to philosophy. 'Most people,' he adds, 'deride or vilify their nature; it is a better thing to endeavour to understand it; and however extravagant my proceeding may be thought, I propose to analyse the properties of that nature as if it were a mathematical figure.' Mind being, as he conceives himself to have shown, nothing else than the idea corresponding to this or that affection of body, we are not, therefore, to think of it as a faculty, but simply and merely as an act. There is no general power called intellect, any more than there is any general abstract volition, but only hic et ille intellectus et hæc et illa volitio.

Again, by the word Mind is understood not merely an act or acts of will or intellect, but all forms also of consciousness of sensation or emotion. The human body being composed of many small bodies, the mind is similarly composed of many minds, and the unity of body and of mind depends on the relation which the component portions maintain towards each other. This is obviously the case with body; and if we can translate metaphysics into common experience, it is equally the case with mind. There are pleasures of sense and pleasures of intellect; a thousand tastes, tendencies, and inclinations form our mental composition; and since one contradicts another, and each has a tendency to become dominant, it is only in the harmonious equipoise of their several activities, in their due and just subordination, that any unity of action or consistency of feeling is possible. After a masterly analysis of all these tendencies (the most complete by far which has ever been made by any moral philosopher), Spinoza arrives at the principles under which unity and consistency can be obtained as the condition upon which a being so composed can look for any sort of happiness; and these principles, arrived at as they are by a route so different, are the same, and are proposed by Spinoza as being the same, as those of the Christian religion.

It might seem impossible in a system which binds together in so inexorable a sequence the relations of cause and effect, to make a place for the action of self-control; but consideration will show that, however vast the difference between those who deny and those who affirm the liberty of the will (in the sense in which the expression is usually understood), it is not a difference which affects the conduct or alters the practical bearings of it. Conduct may be determined by laws—laws as absolute as those of matter; and yet the one as well as the other may be brought under control by a proper understanding of those laws. Now, experience seems plainly to say, that while all our actions arise out of desire—that whatever we do, we do for the sake of something which we wish to be or to obtain—we are differently affected towards what is proposed to us as an object of desire, in proportion as we understand the nature of such object in itself and in its consequences. The better we know, the better we act; and the fallacy of all common arguments against necessitarianism lies in the assumption that it leaves no room for self-direction: it merely insists, in exact conformity with experience, on the conditions under which self-determination is possible. Conduct, according to the necessitarian, depends on knowledge. Let a man certainly know that there is poison in the cup of wine before him, and he will not drink it. By the law of cause and effect, his desire for the wine is overcome by the fear of the pain or the death which will follow. So with everything which comes before him. Let the consequences of any action be clear, definite, and inevitable, and though Spinoza would not say that the knowledge of them will be absolutely sufficient to determine the conduct (because the clearest knowledge may be overborne by violent passion), yet it is the best which we have to trust to, and will do much if it cannot do all.

On this hypothesis, after a diagnosis of the various tendencies of human nature, called commonly the passions and affections, he returns upon the nature of our ordinary knowledge to derive out of it the means for their subordination. All these tendencies of themselves seek their own objects—seek them blindly and immoderately; and the mistakes and the unhappinesses of life arise from the want of due understanding of these objects, and a just moderation of the desire for them. His analysis is remarkably clear, but it is too long for us to enter upon it; the important thing being the character of the control which is to be exerted. To arrive at this, he employs a distinction of great practical utility, and which is peculiarly his own.
