Self - S. Kierkegaard.

The human being is spirit. But what is spirit? Spirit is the self. But what is the self? The self is a relation which relates to itself, or that in the relation which is its relating to itself. The self is not the relation but the relation's relating to itself. A human being is a synthesis of the infinite and the finite, of the temporal and eternal, of freedom and necessity. In short a synthesis. A synthesis is a relation between two terms. Looked at in this way a human being is not yet a self. 

A. That Despair is the Sickness unto Death - The Sickness unto Death

Soren Kierkegaard 

Is signature not required? 46 VII I B 200 - S. Kierkegaard.

... But this I thought was the meaning of life, that the individual shook off the habit of accepting the favours of difference, should that be tempting, steeled himself against its humiliation, should that weigh down on him, in order to find the universal, what is common to all human beings, to concern himself only with that. Oh! how beautiful to lose oneself in this way. But then I thought again that in the having of this concern the meaning of life was to be concerned for oneself as if the particular individual was all there was. Oh! how beautiful thus to find oneself in the universal! If the universal is the rule then the individual is the paradigm [corrected from: demand]; if the universal is the demand then the individual is the fulfillment; if the universal is everything, if the universal says everything, then the particular individual believes that the everything is said about him - him alone.

So if the place and context here did not require a signature, none would be needed, for again it is infinitely inconsequential who has said it (as though the favoured one said it, the one who was one said it, the one who was wronged being in no position to say it, since after all they all have it in them to do it.)
