What is common to all consciousness?

2. What is common to all consciousness?

What distinguishes one consciousness from another?

This will lead to the secondary element.

Consciousness is positively only known to us as a property of animal nature.

Therefore we must not, and indeed cannot, think of it otherwise than as animal consciousness, so that this expression is tautological.

Now, that which in every animal consciousness, even the most imperfect and the weakest, is always present, nay, lies at its foundation, is an immediate sense of longing, and of the alternate satisfaction and non-satisfaction of it, in very different degrees.

This we know to a certain extent a priori. For marvellously different as the innumerable species of animals are, and strange as some new form, never seen before, appears to us, we yet assume beforehand its inmost nature, with perfect certainty, as well known, and indeed fully confided to us.

The animal wills, indeed also what it wills, existence, well-being, life, and propagation; and since in this we presuppose with perfect certainty identity with us, we do not hesitate to attribute to it unchanged all the affections of will which we know in ourselves, and speak at once of its desire, aversion, fear, anger, hatred, love, joy, sorrow, longing, &c. On the other hand, whenever phenomena of mere knowledge come to be spoken of we fall at once into uncertainty. We do not venture403 to say that the animal conceives, thinks, judges, knows: we only attribute to it with certainty ideas in general; because without them its will could not have those emotions referred to above. But with regard to the definite manner of knowing of the brutes and the precise limits of it in a given species, we have only indefinite conceptions, and make conjectures. Hence our understanding with them is also often difficult, and is only brought about by skill, in consequence of experience and practice. Here then lie distinctions of consciousness. On the other hand, a longing, desiring, wishing, or a detesting, shunning, and not wishing, is proper to every consciousness: man has it in common with the polyp.

This is accordingly the essential element in and the basis of every consciousness. The difference of the manifestations of this in the different species of animal beings depends upon the various extension of their sphere of knowledge, in which the motives of those manifestations lie. We understand directly from our own nature all actions and behaviour of the brutes which express movements of the will; therefore, so far, we sympathise with them in various ways. On the other hand, the gulf between us and them results simply and solely from the difference of intellect.

The gulf which lies between a very sagacious brute and a man of very limited capacity is perhaps not much greater than that which exists between a blockhead and a man of genius; therefore here also the resemblance between them in another aspect, which springs from the likeness of their inclinations and emotions, and assimilates them again to each other, sometimes appears with surprising prominence, and excites astonishment. This consideration makes it clear that in all animal natures the will is what is primary and substantial, the intellect again is secondary, adventitious, indeed a mere tool for the service of the former, and is more or less complete and complicated, according to the demands of this service. As a species of animals is furnished with hoofs, claws, hands, wings, horns, or teeth according to the aims of its will, so also is it furnished with a more or less developed brain, whose function is the intelligence necessary for its endurance.

The more complicated the organisation becomes, in the ascending series of animals, the more numerous also are its wants, and the more varied and specially determined the objects which are capable of satisfying them; hence the more complicated and distant the paths by which these are to be obtained, which must now be all known and found: therefore in the same proportion the ideas of the animal must be more versatile, accurate, definite, and connected, and also its attention must be more highly strung, more sustained, and more easily roused, consequently its intellect must be more developed and perfect. Accordingly we see the organ of intelligence, the cerebral system, together with all the organs of sense, keep pace with the increasing wants and the complication of the organism; and the increase of the part of consciousness that has to do with ideas (as opposed to the willing part) exhibits itself in a bodily form in the ever-increasing proportion of the brain in general to the rest of the nervous system, and of the cerebrum to the cerebellum; for (according to Flourens) the former is the workshop of ideas, while the latter is the disposer and orderer of movements. The last step which nature has taken in this respect is, however, disproportionately great.

For in man not only does the faculty of ideas of perception, which alone existed hitherto, reach the highest degree of perfection, but the abstract idea, thought, i.e., reason, and with it reflection, is added. Through this important advance of the intellect, thus 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 more405 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.
