Mental illness, of course, is not literally a "thing" - or physical object - and hence it can "exist" only in the same sort of way in which other theoretical concepts exist.

Men often treat others worse than they treat themselves, but they rarely treat anyone better. It is the height of folly to expect consideration and decency from a person who mistreats himself.

Sex is a body-contact sport. It is safe to watch but more fun to play.

Men are afraid to rock the boat in which they hope to drift safely through life's currents, when, actually, the boat is stuck on a sandbar. They would be better off to rock the boat and try to shake it loose.

The stupid neither forgive nor forget; the naive forgive and forget; the wise forgive but do not forget.

When the psychiatrist approves of a person's actions, he judges that person to have acted with "free choice"; when he disapproves,he judges him to have acted without "free choice." It is small wonder that people find "free choice" a confusing idea: "free choice" appears to refer to what the person being judged (often called the "patient") does, whereas it is actually what the person making the judgment (often a psychiatrist or other mental health worker) thinks.

No further evidence is needed to show that 'mental illness' is not the name of a biological condition whose nature awaits to be elucidated, but is the name of a concept whose purpose is to obscure the obvious.
