It may be asked that when the being that is thus reborn is a different one in respect of its nature, birth, and purposes connected with virtue and vice why should I then be regarded to have any identity with the being that was? Indeed, the only inference that can be drawn is that the entire chain of existences of a particular being is not really a chain of connected links (but that existences in succession are unconnected with one another).[806] Then, again if the being that is the result of a rebirth be really different from what it was in a previous phase of existence, it may be asked what satisfaction can arise to a person from the exercise of the virtue of charity, or from the acquisition of knowledge or of ascetic power, since the acts performed by one are to concentrate upon another person in another phase of existence (without the performer himself being existent to enjoy them?) Another result of the doctrine under refutation would be that one in this life may be rendered miserable by the acts of another in a previous life, or having become miserable may again be rendered happy. By seeing, however, what actually takes place in the world, a proper conclusion may be drawn with respect to the unseen.[807] The separate Consciousness that is the result of rebirth is (according to what may be inferred from the Buddhistic theory of life) different from the Consciousness that had preceded it in a previous life. The manner, however, in which the rise or appearance of that separate Consciousness is explained by that theory does not seem to be consistent or reasonable. The Consciousness (as it existed in the previous life) was the very reverse of eternal, being only transitory, extending as it did till dissolution of the body. That which had an end cannot be taken as the cause for the production of a second Consciousness appearing after the occurrence of the end.
