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. Therefore, in all phenomena, the permanent is the object in itself, that is, the substance (phenomenon); but all that changes or can change belongs only to the mode of the existence of this substance or substances, consequently to its determinations. With this purpose, we reason from an actual existence--an experience in general, to an absolutely necessary condition of that existence. [*Footnote; As to the existence of pure natural science, or physics, perhaps many may still express doubts. To begin with the first question concerning the necessity of a cause: It is a general maxim in philosophy, that whatever begins to exist, must have a cause of existence. We may make the same observation concerning mobility and figure; and upon the whole must conclude, that after the exclusion of colours, sounds, heat and cold from the rank of external existences, there remains nothing, which can afford us a just and constituent idea of body. The cosmological proof, which we are about to examine, retains the connection between absolute necessity and the highest reality; but, instead of reasoning from this highest reality to a necessary existence, like the preceding argument, it concludes from the given. The word reality in the conception of the thing, and the word existence in the conception of the predicate, will not help you out of the difficulty. We foresee and anticipate its change by the imagination; which makes us little satisfyed with the thing: We compare it to ourselves, whose existence is more durable; by which means its inconstancy appears still greater.
