No class, or classes, of my cognitions are distinguished from another class, or classes, by the circumstance that they are mine. This is the very circumstance in which they are all not distinguished from each other—the very point in which the whole of them, whatever their character otherwise may be, are merged in identity. Hence "oneself," or the ego, is the summum genus of cognition—the ultimate generalisation beyond which epistemology cannot ascend. And a very different universal this is, from the ordinary abstract universal named ens, which is the logician's delight.

Were this the case, it would be destitute of that strict universality and necessity which reason claims for it, as the common element in every possible cognition of every possible intelligence. It is this by a necessary law of all cognition. But every necessary truth of reason, although not dependent
