preserve distinctions. Spinoza goes on to say: “What constitutes the real (_actuale_) existence of the human mind is nothing else than the idea of a particular” (individual) “thing, that actually exists,” not of an infinite thing. “The essence of man involves no necessary existence, _i.e._ according to the order of nature a man may just as well be as not be.” For the human consciousness, as it does not belong to essence as an attribute, is a mode—a mode of the attribute of thought. But neither is the body, according to Spinoza, the cause of consciousness, nor is consciousness the cause of the body, but the finite cause is here only the relation of like to like; body is determined by body, conception by conception. “The body can neither determine the mind to thought, nor can the mind determine the body to motion, or rest, or anything else. For all modes of thought have God as Cause, in so far as He is a thinking thing, and not in so far as He is revealed by means of another attribute. What therefore determines the mind to thought, is a mode of thought and not of extension; similarly motion and rest of the body must be derived from another body.”[203] I might quote many other such particular propositions from Spinoza, but they are very formal, and a continual repetition of one and the same thing. Buhle (Gesch. d. neuern Phil. Vol. III. Section 2, pp. 525-528), attributes limited conceptions to Spinoza: “The soul experiences in the body all the ‘other’ of which it becomes aware as outside of the body, and it becomes aware of this ‘other’ only by means of the conceptions of the qualities which the body perceives therein. If, therefore, the body can perceive no qualities of a thing, the soul also can come to no knowledge of it. On the other hand, the soul is equally unable to arrive at the perception of the body which belongs to it; the soul knows not that the body is there, and knows itself even in no other way than by means of the qualities which the body perceives in things which are outside of it, and by means of the conceptions of the same. For the body is an individual thing, determined in a certain manner, which can only gradually, in association with and amidst other individual things, attain to existence, and can preserve itself in existence only as thus connected, combined and associated with others,” _i.e._ in infinite progress; the body can by no means be conceived from itself. “The soul’s consciousness expresses a certain determinate form of a Notion, as the Notion itself expresses a determinate form of an individual thing. But the individual thing, its Notion, and the Notion of this Notion are altogether and entirely one and the same thing, only regarded under different attributes. As the soul is nothing else than the immediate Notion of the body, and is one and the same thing with this, the excellence of the soul can never be anything else than the excellence of the body. The capacities of the understanding are nothing but the
