Ego (n.) is a historical turn the human being took before man's nature could return to itself.
The Ego (n.) owes its priority to the will to certainty — the urge to be certain of oneself, dependent upon oneself alone.
The Ego (n.) understood as acting rather than as a thing means that philosophy must begin not with an active thing but with an active deed.
The Ego (n.) in its empirical form is a thing: the self I can observe in myself is just one more object among objects.
The Ego (n.) cannot be grasped by the categories, because it is what conditions them: what conditions absolutely cannot be determined by what it conditions.
The Ego (n.) defined as a stream of consciousness or a nexus of experience becomes an object to classify — and the 'am' is effaced.
The Ego (n.) is the subject par excellence: a subject that not only has its predicates but knows that it has them — I think, and know myself thinking.
The Ego (n.) in its logical sense is not an abstract, nameless universal but the subject of thinking — and it is always mine; a nameless ego is an absurdity.
The Ego (n.) is not a representation, not an object, not one being among others, but the ground of all representing — and hence the ground of all being.
