of the secondary part of consciousness, it now gains a preponderance over the primary part, in so far as it becomes henceforward the predominantly active part. While in the brute the immediate sense of its satisfied or unsatisfied desire constitutes by far the most important part of its consciousness, and the more so indeed the lower the grade of the animal, so that the lowest animals are only distinguished from plants by the addition of a dull idea, in man the opposite is the case. Vehement as are his desires, even more vehement than those of any brute, rising to the level of passions, yet his consciousness remains continuously and predominantly occupied and filled with ideas and thoughts. Without doubt this has been the principal occasion of that fundamental error of all philosophers on account of which they make thought that which is essential and primary in the so-called soul, i.e., in the inner or spiritual life of man, always placing it first, but will, as a mere product of thought, they regard as only a subordinate addition and consequence of it. But if willing merely proceeded from knowing, how could the brutes, even the lower grades of them, with so very little knowledge, often show such an unconquerable and vehement will? Accordingly, since that fundamental error of the philosophers makes, as it were, the accident the substance, it leads them into mistaken paths, which there is afterwards no way of getting out of. Now this relative predominance of the knowing consciousness over the desiring, consequently of the secondary part over the primary, which appears in man, may, in particular exceptionally favoured individuals, go so far that at the moments of its highest ascendancy, the secondary or knowing part of consciousness detaches itself altogether from the willing part, and passes into free activity for itself, i.e., untouched by the will, and consequently no longer serving it. Thus it becomes purely objective, and the clear mirror of the world, and from it the conceptions of genius then arise, which are the subject of our third book.
