21. On the supposition of there being no (cause: while yet the effect takes place), there results contradiction of the admitted principle; otherwise simultaneousness (of cause and effect).
It has been shown that on the doctrine of general non-permanency, the former momentary existence, as having already been merged in non-existence, cannot be the cause of the later one.--Perhaps now the Bauddha will say that an effect may arise even when there is no cause.--That, we reply, implies the abandonment of a principle admitted by yourself, viz. that the mind and the mental modifications originate when in conjunction with four kinds of causes 1. Moreover, if anything could originate without a cause, there would be nothing to prevent that anything might originate at any time.--If, on the other hand, you should say that we may assume the antecedent momentary existence to last until the succeeding one has been produced, we point out that that would imply the simultaneousness of cause and effect, and so run counter to an accepted Bauddha tenet, viz. that all things 2 are momentary merely.
