The whole notion of sanity may be an attempt to medicalize morality - to speak of the good in the language of health: to make us more accurate, more scientific in our wanting - but by the same token it becomes a form of moral blackmail. It is as if to say: if these are not valued - if these forms of wanting and feeling and speaking and doing - are not cultivated and encouraged and rewarded in the child, then the child will be mad.
People change, but there really are limits. One thing you discover in psychoanalytic treatment is the limits of what you can change about yourself or your life. We are children for a very long time.
Sanity, as the project of keeping ourselves recognizably human, therefore has to limit the range of human experience. To keep faith with recognition we have to stay recognizable. Sanity, in other words, becomes a pressing preoccupation as soon as we recognize the importance of recognition. When we define ourselves by what we can recognize, by what we can comprehend- rather than, say, by what we can describe- we are continually under threat from what we are unwilling and/or unable to see. We are tyrannized by our blind spots, and by whatever it is about ourselves that we find unacceptable.
We have been taught to wish for it, but the wish to be understood may be our most vengeful demand, may be the way we hang on, as adults , to our grudge against our mothers; the way we never let our mothers off the hook for their not meeting our every need. Wanting to be understood, as adults, can be our most violent form of nostalgia.
