It is now no mystery that some quite influential 'philosophers' were 'mentally' ill.

If we, who live outside asylums, act as if we lived in a fictitious world- that is to say, if we are consistent with our beliefs- we cannot adjust ourselves to actual conditions, and so fall into many avoidable semantic difficulties. But the so-called normal person practically never abides by his beliefs, and when his beliefs are building for him a fictitious world, he saves his neck by not abiding by them. A so-called "insane" person acts upon his beliefs, and so cannot adjust himself to a world which is quite different from his fancy.

If words are not things, or maps are not the actual territory, then, obviously, the only possible link between the objective world and the linguistic world is found in structure, and structure alone.

We see what we see because we miss all the finer details.

Man's achievements rest upon the use of symbols.... we must consider ourselves as a symbolic, semantic class of life, and those who rule the symbols, rule us.

Identification makes general sanity and complete adjustment impossible. Training in non-identity plays a therapeutic role with adults.

I think therefore I seem to be.
