When Nietzsche praises egoism it is always in an aggressive or polemical way, against the virtues, against the virtue of disinterestedness (Z III "Of the three evil things"). But in fact egoism is a bad interpretation of the will, just as atomism is a bad interpretation of force. In order for there to be egoism it is necessary for there to be an ego.
Gilles DeleuzeIntuition is neither a feeling, an inspiration nor a disorderly sympathy but a fully developed method.
Gilles DeleuzeTo become imperceptible oneself, to have dismantled love in order to become capable of loving. To have dismantled one's self in order finally to be alone and meet the true double at the other end of the line. A clandestine passenger on a motionless voyage. To become like everybody else; but this, precisely, is a becoming only for one who knows how to be nobody, to no longer be anybody. To paint oneself gray on gray.
