In order to clear up this matter, and learn how the interruption in the appearance of a perception implies not necessarily an interruption in its existence, it will be proper to touch upon some principles, which we shall have occasion to explain more fully afterwards.

That I may avoid all ambiguity and confusion on this head, I shall observe, that I here account for the opinions and belief of the vulgar with regard to the existence of body; and therefore must entirely conform myself to their manner of thinking and of expressing themselves. For, as regards the subterfuge adopted by those who endeavour to evade the consequence--that, if the world is limited as to space and time, the infinite void must determine the existence of actual things in regard to their dimensions--it arises solely from the fact that instead of a sensuous world, an intelligible world--of which nothing is known--is cogitated; instead of a real beginning (an existence, which is preceded by a period in which nothing exists), an existence which presupposes no other condition than that of time; and, instead of limits of extension, boundaries of the universe. Reason can never satisfy us that the existence of any one object does ever imply that of another; so that when we pass from the impression of one to the idea or belief of another, we are not determined by reason, but by custom or a principle of association. It follows that a conception of the understanding or category of the reciprocal sequence of the determinations of phenomena (existing, as they do, apart from each other, and yet contemporaneously), is requisite to justify us in saying that the reciprocal succession of perceptions has its foundation in the object, and to enable us to represent coexistence as objective. But this extension of conceptions beyond the range of our intuition is of no advantage; for they are then mere empty conceptions of objects, as to the possibility or impossibility of the existence of which they furnish us with no means of discovery. But the existence of phenomena cannot be known a priori, and although we could arrive by this path at a conclusion of the fact of some existence, we could not cognize that existence determinately, that is to say, we should be incapable of anticipating in what respect the empirical intuition of it would be distinguishable from that of others.

We cannot, therefore, escape the responsibility of at least a critical solution of the questions of reason, by complaints of the limited nature of our faculties, and the seemingly humble confession that it is beyond the power of our reason to decide, whether the world has existed from all eternity or had a beginning--whether it is infinitely extended, or enclosed within certain limits--whether anything in the world is simple, or whether everything must be capable of infinite divisibility--whether freedom can originate phenomena, or whether everything is absolutely dependent on the laws and order of nature--and, finally, whether there exists a being that is completely unconditioned and necessary, or whether the existence of everything is conditioned and consequently dependent on something external to itself, and therefore in its own nature contingent.

Are you teachable? I answer; It is absurd to introduce--under whatever term disguised--into the conception of a thing, which is to be cogitated solely in reference to its possibility, the conception of its existence.
