Upon the solution of this problem, or upon sufficient proof of the impossibility of synthetical knowledge a priori, depends the existence or downfall of the science of metaphysics. When an object is found by-experience to be always accompanyed with another; whenever the first object appears, though changed in very material circumstances; we naturally fly to the conception of the second, and form an idea of it in as lively and strong a manner, as if we had infered its existence by the justest and most authentic conclusion of our understanding. Otherwise, not exactly the same, but something more than what was cogitated in my conception, would exist, and I could not affirm that the exact object of my conception had real existence. But we cannot cogitate it as a thing determinable by certain distinct predicates relating to its internal nature, for it has no connection with empirical conceptions; nor are we justified in affirming the existence of any such object. In order to free ourselves from this difficulty, we disguise, as much as possible, the interruption, or rather remove it entirely, by supposing that these interrupted perceptions are connected by a real existence, of which we are insensible. Our knowledge of the existence of things reaches as far as our perceptions, and what may be inferred from them according to empirical laws, extend.
