The animal, because it behaves as actively different, in so doing becomes different within itself. In other words, because the animal is involved in a struggle with the outer world, its relation to the latter is untrue, since this outer world has already been transformed in principle (an sich) by the power of the animal lymph; the animal therefore in turning against this food, fails to recognize its own self. But the immediate result of this is simply that when the animal comes to itself and recognizes itself as this power, it is angry with itself for getting involved with external powers and it now turns against itself and its false opinion; but in doing so it throws off its outward-turned activity and returns into itself.
