§ 48.
Our question, then, in the first of the two forms suggested, must be answered in the negative. A fact consisting of mere feeling, in the sense supposed, is a contradiction, an impossibility. This does not of course mean that no being can feel which does not also think. We are not called on here to enquire whether there are really animals which feel but have not the capacity of thinking. All that the present argument would lead us to maintain would be that, so far as they feel without thinking, their feelings are not facts for them--for their consciousness. Their feelings are facts; but they are facts only so far as determined by relations, which exist only for a thinking consciousness and otherwise could not exist. And, in like manner, that large part of our own sensitive life which goes on without being affected by conceptions, is a series of facts with the determination of which, indeed, thought, as ours or in us, has nothing to do, but which not the less depends for its existence as a series of facts on the action of the same subject which, in another mode of its action, enables us to know them. But in saying this, it may be objected, we have already admitted that there is such a thing as a merely feeling consciousness; and, in the presence of this admission, what becomes of the denial to feeling of any separate or independent reality? The answer is that the distinction of the merely feeling consciousness is just this, that what it is really it is not consciously--that the relations by which it is really determined do not exist for it, but for the thinking consciousness on which it and they alike depend for being what they are. Its very characteristics as a merely feeling consciousness depend on conditions, in the universe of things, by which it would not be conditioned if it were really no more than it feels itself to be; if it were not relative to, and had not its existence for, another form of consciousness which comprehends it and its conditions.
