(1) To speak of thought or objective thought as the heart [and soul of the world, may seem to be ascribing consciousness to the things of nature. We feel a certain repugnance against making thought the inward function of things, especially as we speak of thought as marking the divergence of man from nature. It would be necessary, therefore, if we use the term thought at all, to speak of nature as the system of unconscious thought, or, to use Schelling's expression, a petrified intelligence. And in order to prevent misconception, thought-form or thought-type should be substituted for the ambiguous term thought. From what has been said the principles of logic are to be sought in a system of thought-types or fundamental categories, in which the opposition between subjective and objective, in its usual sense, vanishes. The signification thus attached to thought and its characteristic forms may be illustrated by the ancient saying that 'νοῧς governs the world,' or by our own phrase that 'Reason is in the world: which means that Reason is the soul of the world it inhabits, its immanent principle, its most proper and inward nature, its universal. Another illustration is offered by the circumstance that in speaking of some definite animal we say it is (an) animal. Now, the animal, _quâ_ animal, cannot be shown; nothing can be pointed out excepting some special animal. Animal, _quâ_ animal, does not exist: it is merely the universal nature of the individual animals, whilst each existing animal is a more concretely, defined and particularised thing. But to be an animal,--the law of kind which is the universal in this case,--is the property of the particular animal, and constitutes its definite essence. Take away from the dog its animality, and it becomes impossible to say what it is. All things have a permanent inward nature, as well as an outward existence. They live and die, arise and pass away; but their essential and universal part is the kind; and this means much more than something _common_ to them all.
