3. Individual beings, which considered under the attribute of thought are ideas, and under the attribute of extension are bodies, Spinoza comprehends under the conception of accidence, or, as he calls it, mode. By modes we are therefore to understand the changing forms of substance. The modes stand related to the substance as the rippling waves of the sea to the water of the sea, as forms constantly disappearing and never having a real being. In fact this example goes too far, for the waves of the sea are at least a part of the water of the sea, while the modes, instead of being parts of the substance, are essentially nothing and without being. The finite has no existence as finite; only the infinite substance has actual existence. Substance, therefore, could not be regarded more falsely than if it should be viewed as made up of modes. That would be, Spinoza remarks, as if one should say that the line is made up out of points. It is just as false to affirm that Spinoza identifies God and the world. He identifies them so little that he would rather say that the world, as world, i. e. as an aggregate of individuals, does not at all exist; we might rather say with Hegel that he denies the world (his system is an acosmism), than with Bayle, that he makes every thing God, or that he ascribes divinity to every thing.
Whence do finite things or individuals arise, if they can have no existence by the side of substance? They are only the product of our deceptive apprehension. There are two chief ways of knowledge—the intuitive, through the reason, and the imaginative. To the latter belong the knowledge of experience, and all that is abstract, superficial, and confused; to the former, the collection of all fitting (adequate) ideas. It is only the fault of the imagination that we should look upon the world as a manifoldness of individuals; the manifoldness is only a form of representation. The imagination isolates and individualizes what the reason sees together in its unity. Hence it is only as considered through the imagination (experience or opinion) that modes are things; the reason looks upon them as necessary, or, what is the same thing, as eternal.
Such are the fundamental thoughts and features of Spinoza’s system. His practical philosophy yet remains to be characterized and in a few words. Its chief propositions follow necessarily from the metaphysical grounds already cited. First, it follows from these, that what is called free will cannot be admitted. For since man is only a mode, he, like every other mode, stands in an endless series of conditioning causes, and no free will can therefore be predicated of him. The will must thus, like the body (and the resolution of the will is only a modification of the body), be determined by something other than itself. Men regard themselves as free only because they are conscious of their actions and not of the determining causes. Just so the notions which one commonly connects with the words good and evil, rest on an error as follows at once from the conception of the absolute divine causality. Good and evil are not something actually in the things themselves, but only express relative conceptions which we have formed from a comparison of things with one another. Thus, by observing certain things we form a certain universal conception, which we thereupon treat as though it were the rule for the being and acting of all individuals, and if any individual varies from this conception we fancy that it does not correspond to its nature, and is incomplete. Evil or sin is therefore only something relative, for nothing happens against God’s will. It is only a simple negation or deprivation, which only seems to be a reality in our representation. With God there is no idea of the evil. What is therefore good and what evil? That is good which is useful to us, and that evil which hinders us from partaking of a good. That, moreover, is useful to us which brings us to a greater reality, which preserves and exalts our being. But our true being is knowledge, and hence that only is useful to us which aids us in knowing; the highest good is the knowledge of God; the highest virtue of the mind is to know and love God. From the knowledge of God we gain the highest gladness and joy of the mind, the highest blessedness. Blessedness, hence, is not the reward of virtue, but virtue itself.
The grand feature of Spinoza’s philosophy is that it buries every thing individual and particular, as a finite, in the abyss of the divine substance. With its view unalterably fixed upon the eternal one, it loses sight of every thing which seems actual in the ordinary notions of men. But its defect consists in its inability to transform this negative abyss of substance into the positive ground of all-being and becoming. The substance of Spinoza, has been justly compared to the lair of a lion, which many footsteps enter, but from which none emerge. The existence of the phenomenal world, though it be only the apparent and deceptive reality of the finite, Spinoza does not explain. With his abstract conception of substance he cannot explain it. And yet the means to help him out of the difficulty lay near at hand. He failed to apply universally his fundamental principle that all determination is negation; he applied it only to the finite, but the abstract infinite, in so far as it stands over against the finite, is also a determinate; this infinite must be denied by its negation, which is the case when a finite world is posited. Jacob Boehme rightly apprehended this, when he affirmed, that without a self-duplication, without an ingress into the limited, the finite, the original ground of things is an empty nothing (cf. § XXIII. 8). So the original ground of Spinoza is a nothing, a purely indeterminate, because with him substance was only a principle of unity and not also a principle of distinction, because its attributes, instead of being an expression of an actual difference and a positive distinction to itself, are rather wholly indifferent to itself. The system of Spinoza is the most abstract Monotheism that can be thought. It is not accidental that its author, a Jew, should have brought out again this view of the world, this view of absolute identity, for it is in a certain degree with him only a consequence of his national religion—an echo of the Orient.
SECTION XXVII.
IDEALISM AND REALISM.
We have now reached a point of divergence in the development of philosophy. Descartes had affirmed and attempted to mediate the opposition, between thought and being, mind and matter. This mediation, however, was hardly successful, for the two sides of the opposition he had fixed in their widest separation, when he posited them as two substances or powers, which reciprocally negated each other. The followers of Descartes sought a more satisfactory mediation, but the theories to which they saw themselves driven, only indicated the more clearly that the whole premise from which they started must be given up. At length Spinoza abandoned the false notion, and took away its substantiality from each of the two opposed principles. Mind and matter, thought and extension, are now one in the infinite substance. Yet they are not one in themselves, which would be the only true unity of the two. That they are one in the substance is of little avail, since they are indifferent to the substance, and are not immanent distinctions in it. Thus even with Spinoza the two remain strictly separate. The ground of this isolation we find in the fact that Spinoza himself did not sufficiently renounce the Cartesian notion, and thus could not escape the Cartesian dualism. With him, as with Descartes, thought is only thought, and extension only extension, and in such an apprehension of the two, the one necessarily excludes the other. If we would find an inner mediation for the two, we must cease to abstract every thing essential from each. The opposite sides must be mediated even in their strictest opposition. To do this, two ways alone were possible. A position could be taken either on the material or on the ideal side, and the attempt made to explain the ideal under the material, or the material under the ideal, comprehending one through the other. Both these attempts were in fact made, and at about the same time. The two parallel courses of a one-sided idealism, and a one-sided realism (Empiricism, Sensualism, Materialism), now begin their development.
