That the self-consciousness is the fixed point, to which for us all is mortised and annexed, needs no further proof. But that the self-consciousness may be the modification of a higher form of being, perhaps of a higher consciousness, and this again of a yet higher, and so on in an infinite regressus; in short, that self-consciousness may be itself something explicable into something, which must lie beyond the possibility of our knowledge, because the whole synthesis of our intelligence is first formed in and through the self-consciousness, does not at all concern us as transcendental philosophers. For to us, self-consciousness is not a kind of being, but a kind of knowing, and that too the highest and farthest that exists for us. It may however be shown, and has in part already been shown earlier, that even when the Objective is assumed as the first, we yet can never pass beyond the principle of self-consciousness. Should we attempt it, we must be driven back from ground to ground, each of which would cease to be a ground the moment we pressed on it. We must be whirled down the gulf of an infinite series. But this would make our reason baffle the end and purpose of all reason, namely, unity and system. Or we must break off the series arbitrarily, and affirm an absolute something that is in and of itself at once cause and effect (causa sui), subject and object, or rather the absolute identity of both. But as this is inconceivable, except in a self-consciousness, it follows, that even as natural philosophers we must arrive at the same principle from which as transcendental philosophers we set out; that is, in a self-consciousness in which the principium essendi does not stand to the principlum cognoscende in the relation of cause to effect, but both the one and the other are co-inherent and identical. Thus the true system of natural philosophy places the sole reality of things in an ABSOLUTE, which is at once causa sui et effectus, pataer autopator, uios heautou--in the absolute identity of subject and object, which it calls nature, and which in its highest power is nothing else than self-conscious will or intelligence. In this sense the position of Malebranche, that we see all things in God, is a strict philosophical truth; and equally true is the assertion of Hobbes, of Hartley, and of their masters in ancient Greece, that all real knowledge supposes a prior sensation. For sensation itself is but vision nascent, not the cause of intelligence, but intelligence itself revealed as an earlier power in the process of self-construction.
