An unfinished coffin on black tressels, which stood in the middle of the shop, looked so gloomy and death-like that a cold tremble came over him, every time his eyes wandered in the direction of the dismal object: from which he almost expected to see some frightful form slowly rear its head, to drive him mad with terror.
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.
Madness is the first step towards unselfishness. Be mad and tell us what is behind the veil of "sanity". The purpose of life is to bring us closer to those secrets, and madness is the only means.
