"What we call 'normal' is a product of repression, denial, splitting, projection, introjection and other forms of destructive action on experience. It is radically estranged from the structure of being. The more one sees this, the more senseless it is to continue with generalized descriptions of supposedly specifically schizoid, schizophrenic, hysterical 'mechanisms.' There are forms of alienation that are relatively strange to statistically 'normal' forms of alienation. The 'normally' alienated person, by reason of the fact that he acts more or less like everyone else, is taken to be sane. Other forms of alienation that are out of step with the prevailing state of alienation are those that are labeled by the 'formal' majority as bad or mad."
