" A human being is spirit. But what is spirit? Spirit is the self. But what is the self? The self is a relation that relates itself to itself or is the relation's relating itself to itself in the relation; the self is not the relation but is the relation's relating itself to itself. A human being is a synthesis of the infinite and the finite, of the temporal and the eternal, of freedom and necessity, in short, a synthesis. A synthesis is a relation between two. Considered in this way a human being is still not a self.... In the relation between two, the relation is the third as a negative unity, and the two relate to the relation and in the relation to the relation; thus under the qualification of the psychical the relation between the psychical and the physical is a relation. If, however, the relation relates itself to itself, this relation is the positive third, and this is the self. "

" ... he will seek vainly to the right and to the left and in the newspapers for a guarantee that he has actually been amused.
For a sophisticated person, on the other hand, who is still unembarrassed enough to dare to be amused all by himself, who has enough self-confidence to know, without seeking advice from anyone else, whether he has been amused, farce will perhaps have a very special meaning, in that now with the spaciousness of abstraction and now with the presentation of a tangible actuality, it will affect his mood differently.
He will, of course refrain from bringing a fixed and definite mood with him so that everything affects him in relation to that mood. He will have perfected his mood, in that he will be able to keep himself in a condition where no particular mood is present, but where all moods are possible. "
