I have no doubt that the threshold [of suffering] may be crossed if a late applicant with no means and no alternative sources of support, unable to support himself is, by deliberate action of the state, denied shelter, food or the most basic necessities of life.

If I am fool, it is, at least, a doubting one; and I envy no one the certainty of his self-approved wisdom.
