“...[I]n impressing our seal and mark upon others, in acting upon our neighbors in order to dominate them, in giving ourselves to them in order that we may eternalize ourselves so far as we can.  Our greatest endeavor must be to make ourselves irreplaceable; to make the theoretical fact … that no one else can fill the gap that will be left when we die, a practical truth”


(Miguel de Unamuno,

Tragic Sense of Life, 298-9).
