What Makes Man Different from Animals.9

"But this elevation of the implicit into self-conscious knowledge introduces a tremendous difference. It is the infinite difference which, for example, separates man from animals. Man is an animal, but even in his animal functions, he is not confined to the implicit, as the animal is; he becomes conscious of them, recognizes them, and lifts them, as, for instance, the process of digestion, into self-conscious science. In this way man breaks the barrier of his implicit and immediate character, so that precisely because he knows that he is an animal, he ceases to be an animal and attains knowledge of himself as spirit."
