the truth of which has to be proved; and accordingly the essential criterion so far as the proposition is concerned, is merely whether the predicate is adequate to the subject or not, and idea or ordinary thought, on which the presupposition is based, is taken as deciding the truth. But the main and only concern of knowledge, the claims of which have not been satisfied, and which have not even been taken into account, is just to find out whether this very presupposition contained in the subject, and consequently the further specification which it gets through the predicate, is the totality of the proposition and is true.
This is something which reason forces us to, working from within outward, unconsciously as it were. From what has been already adduced, it is evident that an attempt has been made to find what are called several proofs of the existence of God: the one set of which is based on one of the propositions above indicated, that, namely, in which Being is the subject and constitutes the presupposition, and in which the Infinite is a characteristic posited in it by means of mediation; and the other set of which has for its basis the reverse proposition, by means of which the first of the propositions loses its one-sidedness. Here the defective element, namely, the fact that Being is presupposed, is cancelled, and conversely it is now Being which has to be posited as mediated.
What has to be accomplished by the proof has accordingly been stated in a complete enough way, but still the nature of the proof itself as such has been in consequence not touched upon. For each of the propositions has been stated separately, the proof of it accordingly starts from the presupposition which the subject contains, and which has each time to be shown to be necessary through the other, and not as immediately necessary. Either proposition presupposes the other, and no true beginning can be found for them. For this very reason it appears at first to be a matter of indifference where a beginning is made. Only the starting-point is not a matter of indifference, and
