contradictory states pass through our consciousness, they did not succeed in envisaging consciousness itself, the "I." To ask a man about his "I" is like asking him about his body. And note that in speaking of the "I," I speak of the concrete and personal "I," not of the "I" of Fichte, but of Fichte himself, the man Fichte.

That which determines a man, that which makes him one man, one and not another, the man he is and not the man he is not, is a principle of unity and a principle of continuity. A principle of unity firstly in space, thanks to the body, and next in action and intention. When we walk, one foot does not go forward and the other backward, nor, when we look, if we are normal, does one eye look towards the north and the other towards the south. In each moment of our life we entertain some purpose, and to this purpose the synergy of our actions is directed. Notwithstanding the next moment we may change our purpose. And in a certain sense a man is so much the more a man the more unitary his action. Some there are who throughout their whole life follow but one single purpose, be it what it may.
