These patients have turned away from outer reality; it is for this reason that they are more aware than we of inner reality and can reveal to us things which without them would remain impenetrable.
Sigmund FreudAgainst the suffering which may come upon one from human relationships the readiest safeguard is voluntary isolation, keeping oneself aloof from other people. The happiness which can be achieved along this path is, as we see, the happiness of quietness. Against the dreaded external world one can only defend oneself by some kind of turning away from it, if one intends to solve the task by oneself.
