Footnote 2: This argument is not conclusive, nor is it at all necessary. Animals have memory; and there is no more reason why their waking sensations, emotions, and acts should not repeat themselves in dreams than there is in the case of men. The difference between the soul of man and the soul of the brute is constituted by the presence of the gift of reason, or the faculty of knowing necessary and universal truths in the former, and its absence in the latter.--Ed.
