A [wo]man who is unconscious of [her/]himself acts in a blind, instinctive way and is in addition fooled by all the illusions that arise when he sees everything that he is not conscious of in himself coming to meet him from outside as projections upon his neighbour.
An instinct is an agent which performs blindly and ignorantly a work of intelligence and knowledge.
Beasts, birds, and insects, even to the minutest and meanest of their kind, act with the unerring providence of instinct; man, the while, who possesses a higher faculty, abuses it, and therefore goes blundering on.
