Following his tripartite division of knowledge, he finds all kinds of it arrange themselves under one of two classes, and to be either adequate or inadequate. By adequate knowledge he does not mean what is exhaustive and complete, but what, as far as it goes, is distinct and unconfused: by inadequate, he means what we know merely as fact either derived from our own sensations, or from the authority of others, while of the connexion of it with other facts, of the causes, effects, or meaning of it we know nothing. We may have an adequate idea of a circle, though we are unacquainted with all the properties which belong to it; we conceive it distinctly as a figure generated by the rotation of a line, one end of which is stationary. Phenomena, on the other hand, however made known to us—phenomena of the senses, and phenomena of experience, as long as they remain phenomena merely, and unseen in any higher relation—we can never know except as inadequately. We cannot tell what outward things are by coming in contact with certain features of them. We have a very imperfect acquaintance even with our own bodies, and the sensations which we experience of various kinds rather indicate to us the nature of these bodies themselves than of the objects which affect them. Now, it is obvious that the greater part of mankind act only upon knowledge of this latter kind. The amusements, even the active pursuits, of most of us remain wholly within the range of uncertainty, and, therefore, are full of hazard and precariousness: little or nothing issues as we expect. We look for pleasure and we find pain; we shun one pain and find a greater; and thus arises the ineffectual character which we so complain of in life—the disappointments, failures, mortifications which form the material of so much moral meditation on the vanity of the world. Much of all this is inevitable from the constitution of our nature. The mind is too infirm to be entirely occupied with higher knowledge. The conditions of life oblige us to act in many cases which cannot be understood by us except with the utmost inadequacy; and the resignation to the higher will which has determined all things in the wisest way, is imperfect in the best of us. Yet much is possible, if not all; and, although through a large tract of life 'there comes one event to all, to the wise and to the unwise,' 'yet wisdom excelleth folly as far as light excelleth darkness.' The phenomena of experience, after inductive experiment, and just and careful consideration, arrange themselves under laws uniform in their operation, and furnishing a guide to the judgment; and over all things, although the interval must remain unexplored for ever, because what we would search into is Infinite, may be seen the beginning of all things, the absolute eternal God. 'Mens humana,' Spinoza continues, 'quædam agit, quædam vero patitur.' In so far as it is influenced by inadequate ideas—'eatenus patitur'—it is passive and in bondage, it is the sport of fortune and caprice: in so far as its ideas are adequate—'eatenus agit'—it is active, it is itself. While we are governed by outward temptations, by the casual pleasures, by the fortunes or the misfortunes of life, we are but instruments, yielding ourselves to be acted upon as the animal is acted on by its appetites, or the inanimate matter by the laws which bind it; we are slaves—instruments, it may be, of some higher purpose in the order of nature, but in ourselves nothing; instruments which are employed for a special work, and which are consumed in effecting it. So far, on the contrary, as we know clearly what we do, as we understand what we are, and direct our conduct not by the passing emotion of the moment, but by a grave, clear, and constant knowledge of what is really good, so far we are said to act—we are ourselves the spring of our own activity—we pursue the genuine well-being of our entire nature, and that we can always find, and it never disappoints us when found.
All things desire life; all things seek for energy, and fuller and ampler being. The component parts of man, his various appetites and passions, are seeking larger activity while pursuing each its immoderate indulgence; and it is the primary law of every single being that it so follows what will give it increased vitality. Whatever will contribute to such increase is the proper good of each; and the good of man as a united being is measured and determined by the effect of it upon his collective powers. The appetites gather power from their several objects of desire; but the power of the part is the weakness of the whole; and man as a collective person gathers life, being, and self-mastery only from the absolute good,—the source of all real good, and truth, and energy,—that is, God. The love of God is the extinction of all other loves and all other desires. To know God, as far as man can know him, is power, self-government, and peace. And this is virtue, and this is blessedness.
Thus, by a formal process of demonstration, we are brought round to the old conclusions of theology; and Spinoza protests that it is no new doctrine which he is teaching, but that it is one which in various dialects has been believed from the beginning of the world. Happiness depends on the consistency and coherency of character, and that coherency can only be given by the knowledge of the One Being, to know whom is to know all things adequately, and to love whom is to have conquered every other inclination. The more entirely our minds rest on him—the more distinctly we regard all things in their relation to him, the more we cease to be under the dominion of external things; we surrender ourselves consciously to do his will, and as living men and not as passive things we become the instruments of his power. When the true nature and true causes of our affections become clear to us, they have no more power to influence us. The more we understand, the less can feeling sway us; we know that all things are what they are, because they are so constituted that they could not be otherwise, and we cease to be angry with our brother, because he disappoints us; we shall not fret at calamity, nor complain of fortune, because no such thing as fortune exists; and if we fail it is better than if we had succeeded, not perhaps for ourselves, yet for the universe. We cannot fear, when nothing can befall us except what God wills, and we shall not violently hope, when the future, whatever it be, will be the best which is possible. Seeing all things in their place in the everlasting order, Past and Future will not affect us. The temptation of present pleasure will not overcome the certainty of future pain, for the pain will be as sure as the pleasure, and we shall see all things under a rule of adamant. The foolish and the ignorant are led astray by the idea of contingency, and expect to escape the just issues of their actions; the wise man will know that each action brings with it its inevitable consequences, which even God cannot change without ceasing to be himself.
In such a manner, through all the conditions of life, Spinoza pursues the advantages which will accrue to man from the knowledge of God, God and man being what his philosophy has described them. His practical teaching is singularly beautiful; although much of its beauty is perhaps due to associations which have arisen out of Christianity, and which in the system of Pantheism have no proper abiding place. Retaining, indeed, all that is beautiful in Christianity, he even seems to have relieved himself of the more fearful features of the general creed. He acknowledges no hell, no devil, no positive and active agency at enmity with God; but sees in all things infinite gradations of beings, all in their way obedient, and all fulfilling the part allotted to them. Doubtless a pleasant exchange and a grateful deliverance, if only we could persuade ourselves that a hundred pages of judiciously arranged demonstrations could really and indeed have worked it for us; if we could indeed believe that we could have the year without its winter, day without night, sunlight without shadow. Evil is unhappily too real a thing to be so disposed of.
But if we cannot believe Spinoza's system taken in its entire completeness, yet we may not blind ourselves to the disinterestedness and calm nobility which pervades his theories of human life and obligation. He will not hear of a virtue which desires to be rewarded. Virtue is the power of God in the human soul, and that is the exhaustive end of all human desire. 'Beatitudo non est virtutis pretium, sed ipsa virtus. Nihil aliud est quam ipsa animi acquiescentia, quæ ex Dei intuitivâ cognitione oritur.' The same spirit of generosity exhibits itself in all his conclusions. The ordinary objects of desire, he says, are of such a kind that for one man to obtain them is for another to lose them; and this alone would suffice to prove that they are not what any man should labour after. But the fulness of God suffices for us all; and he who possesses this good desires only to communicate it to every one, and to make all mankind as happy as himself. And again:—'The wise man will not speak in society of his neighbour's faults, and sparingly of the infirmity of human nature; but he will speak largely of human virtue and human power, and of the means by which that nature can best be perfected, so to lead men to put away that fear and aversion with which they look on goodness, and learn with relieved hearts to love and desire it.' And once more:—'He who loves God will not desire that God should love him in return with any partial or particular affection, for that is to desire that God for his sake should change his everlasting nature and become lower than himself.'
One grave element, indeed, of a religious faith would seem in such a system to be necessarily wanting. Where individual action is resolved into the modified activity of the Universal Being, all absorbing and all evolving, the individuality of the personal man is but an evanescent and unreal shadow. Such individuality as we now possess, whatever it be, might continue to exist in a future state as really as it exists in the present, and those to whom it belongs might be anxious naturally for its persistence. Yet it would seem that if the soul be nothing except the idea of a body actually existing, when that body is decomposed into its elements, the soul corresponding to it must accompany it into an answering dissolution. And this, indeed, Spinoza in one sense actually affirms, when he denies to the mind any power of retaining consciousness of what has befallen it in life, 'nisi durante corpore.' But Spinozism is a philosophy full of surprises; and our calculations of what must belong to it are perpetually baffled. The imagination, the memory, the senses, whatever belongs to inadequate perception, perish necessarily and eternally; and the man who has been the slave of his inclinations, who has no knowledge of God, and no active possession of himself, having in life possessed no personality, loses in death the appearance of it with the dissolution of the body.
Nevertheless, there is in God an idea expressing the essence of the mind, united to the mind as the mind is united to the body, and thus there is in the soul something of an everlasting nature which cannot utterly perish. And here Spinoza, as he often does in many of his most solemn conclusions, deserts for a moment the thread of his demonstrations, and appeals to the consciousness. In spite of our non-recollection of what passed before our birth, in spite of all difficulties from the dissolution of the body, 'Nihilominus,' he says, 'sentimus experimurque nos æternos esse. Nam mens non minus res illas sentit quas intelligendo concipit, quam quas in memoriâ habet. Mentis enim oculi quibus res videt observatque sunt ipsæ demonstrationes.'
This perception, immediately revealed to the mind, falls into easy harmony with the rest of the system. As the mind is not a faculty, but an act or acts,—not a power of perception, but the perception itself, in its high union with the highest object (to use the metaphysical language which Coleridge has made popular and partially intelligible), the object and the subject become one. If knowledge be followed as it ought to be followed, and all objects of knowledge be regarded in their relations to the One Absolute Being, the knowledge of particular outward things, of nature, or life, or history, becomes, in fact, knowledge of God; and the more complete or adequate such knowledge, the more the mind is raised above what is perishable in the phenomena to the idea or law which lies beyond them. It learns to dwell exclusively upon the eternal, not upon the temporary; and being thus occupied with the everlasting laws, and its activity subsisting in its perfect union with them, it contracts in itself the character of the objects which possess it. Thus we are emancipated from the conditions of duration; we are liable even to death only quatenus patimur, as we are passive things and not active intelligences; and the more we possess such knowledge and are possessed by it, the more entirely the passive is superseded by the active—so that at last the human soul may 'become of such a nature that the portion of it which will perish with the body in comparison with that of it which shall endure, shall be insignificant and nullius momenti.' (Eth. v. 38.)
Such are the principal features of a philosophy, the influence of which upon Europe, direct and indirect, it is not easy to over-estimate. The account of it is far from being an account of the whole of Spinoza's labours; his 'Tractatus Theologico-Politicus' was the forerunner of German historical criticism; the whole of which has been but the application of principles laid down in that remarkable work. But this is not a subject on which, upon the present occasion, we have cared to enter. We have designedly confined ourselves to the system which is most associated with the name of its author. It is this which has been really powerful, which has stolen over the minds even of thinkers who imagine themselves most opposed to it. It has appeared in the absolute Pantheism of Schelling and Hegel, in the Pantheistic Christianity of Herder and Schleiermacher. Passing into practical life it has formed the strong, shrewd judgment of Goethe, while again it has been able to unite with the theories of the most extreme materialism.
It lies too, perhaps (and here its influence has been unmixedly good), at the bottom of that more reverent contemplation of nature which has caused the success of our modern landscape painting, which inspired Wordsworth's poetry, and which, if ever physical science is to become an instrument of intellectual education, must first be infused into the lessons of nature; the sense of that 'something' interfused in the material world—
