The onlooker might have feigned ends and objects of forethought, as we do in the case of the water that seeks its own level, or in that of the vacuum which nature abhors. But the particles of matter would have remained unconscious of their collocation, and all nature would have been insensible of their changing arrangement. We only, the possible spectators of that process, by virtue of our own interests and habits, could see any progress or culmination in it. We should see culmination where the result attained satisfied our practical or aesthetic demands, and progress wherever such a satisfaction was approached. But apart from ourselves, and our human bias, we can see in such a mechanical world no element of value whatever. In removing consciousness, we have removed the possibility of worth. But it is not only in the absence of all consciousness that value would be removed from the world; by a less violent abstraction from the totality of human experience, we might conceive beings of a purely intellectual cast, minds in which the transformations of nature were mirrored without any emotion. Every event would then be noted, its relations would be observed, its recurrence might even be expected; but all this would happen without a shadow of desire, of pleasure, or of regret. No event would be repulsive, no situation terrible. We might, in a word, have a world of idea without a world of will. In this case, as completely as if consciousness were absent altogether, all value and excellence would be gone. So that for the existence of good in any form it is not merely consciousness but emotional consciousness that is needed. Observation will not do, appreciation is required. _Preference is ultimately irrational._ Sec. 2. We may therefore at once assert this axiom, important for all moral philosophy and fatal to certain stubborn incoherences of thought, that there is no value apart from some appreciation of it, and no good apart from some preference of it before its absence or its opposite. In appreciation, in preference, lies the root and essence of all excellence. Or, as Spinoza clearly expresses it, we desire nothing because it is good, but it is good only because we desire it.
