“Solitude is the profoundest fact of the human condition.
Man is the only being who knows he is alone, and the only one who seeks out another.
His nature - if that word can be used in reference to man, who has ‘invented’ himself by saying ‘no’ to nature - consists in his longing to realize himself in another.
Man is nostalgia and a search for communion.
Therefore, when he is aware of himself he is aware of his lack of another, that is, of his solitude.”
― Octavio Paz, The Labyrinth of Solitude and Other Writings
