body; this idea is synthetic combination, as we shall immediately see. “The ideas, whether of the attributes of God or of individual things, do not recognize as their efficient cause their objects themselves, or the things perceived, but God Himself, in so far as He is that which thinks.”[202] Buhle (Geschichte der neuern Philos. Vol. III. Section II. p. 524) sums up these propositions of Spinoza thus: “Thought is inseparably bound up with extension; therefore all that takes place in extension must also take place in consciousness.” Spinoza, however, also accepts both in their separation from one another. The idea of body, he writes (Epistol. LXVI. p. 673), includes only these two in itself, and does not express any other attributes. The body which it represents is regarded under the attribute of extension; but the idea itself is a mode of thought. Here we see a dividing asunder; mere identity, the undistinguishable nature of all things in the Absolute, is insufficient even for Spinoza. The _individuum_, individuality itself, is thus defined by Spinoza (Ethic. P. II. Prop. XIII. Defin. p. 92): “When several bodies of the same or of different magnitudes are so pressed together that they rest on one another, or when, moving with like or different degrees of rapidity, they communicate their movement to one another in a certain measure, we say that such bodies are united to one another, and that all together they form one body or individuum, which by this union distinguishes itself from all the other bodies.” Here we are at the extreme limit of Spinoza’s system, and it is here that his weak point appears. Individuation, the one, is a mere synthesis; it is quite a different thing from the Ichts or self-hood of Boehme (_supra_, pp. 205-207), since Spinoza has only universality, thought, and not self-consciousness. If, before considering this in reference to the whole, we take it from the other side, namely from the understanding, the distinction really falls under that head; it is not deduced, it is found. Thus, as we have already seen (p. 270) “the understanding in act (_intellectus actu_), as also will, desire, love, must be referred to _natura naturata_, not to _natura naturans_. For by the understanding, as recognized for itself, we do not mean absolute thought, but only a certain mode of thought—a mode which is distinct from other modes like desire, love, etc., and on that account must be conceived by means of absolute thought, _i.e._ by means of an attribute of God which expresses an eternal and infinite essentiality of thought; without which the understanding, as also the rest of the modes of thought, could neither be nor be conceived to be.” (Spinoza, Ethices, P. I. Propos. XXXI. pp. 62, 63). Spinoza is unacquainted with an infinity of form, which would be something quite different from that of rigid, unyielding substance. What is requisite is to recognize God as the essence of essences, as universal substance, identity, and yet to
