While the brute cannot say 'I,' man can, because it is his nature to think. Now in the 'Ego' there are a variety of contents, derived both from within and from, without, and according to the nature of these contents our state may be described as perception, or conception, or reminiscence. But in all of them the 'I' is found: or in them all thought is present. Man, therefore, is always thinking, even in his perceptions: if he observes anything, he always observes it as a universal, fixes on a single point which he places in relief, thus withdrawing his attention from other points, and takes it as abstract and universal, even if the universality be only in form. In the case of our ordinary conceptions, two things may happen. Either the contents are moulded by thought, but not the form: or, the form belongs to thought and not the contents. In using such terms, for instance, as anger, rose, hope, I am speaking of things which I have learnt in the way of sensation, but I express these contents in a universal mode, that is, in the form of thought. I have left out much that is particular and given the contents in their generality: but still the contents remain sense-derived. On the other hand, when I represent God, the content is undeniably a product of pure thought, but the form still retains the sensuous limitations which it has as I find it immediately present in myself. In these generalised images the content is not merely and simply sensible, as it is in a visual inspection; but either the content is sensuous and the form appertains to thought, or _vice versâ._ In the first case the material is given to us, and our thought supplies the form: in the second case the content which has its source in thought is by means of the form turned into a something given, which accordingly reaches the mind from without.
