There is no such thing as mental illness, hence also no such thing as psychotherapy.

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.

The cruelty intrinsic to the workhouse system was excused by the need to discourage idleness, much as the malice intrinsic to the mental hospital system has been excused by the need to provide treatment.

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.

A phenomenon that might seem only backwards or silly when expressed at a social level becomes madness at the individual level.

Mental illness turns people inwards. That's what I reckon. It keeps up forever trapped by the pain of our own minds, in the same way that the pain of a broken leg or a cut thumb will grab your attention, holding it so tightly that your good leg or your good thumb seem to cease to exist.
