In the NUDE, all that is not beautiful is obscene.
— Robert Bresson

Obscenity is whatever happens to shock some elderly and ignorant magistrate.
Bertrand Russell obscenely quote

The secret thoughts of a man run over all things, holy, profane, clean, obscene, grave, and light, without shame or blame.
— Thomas Hobbes

Women should be obscene and not heard.
— Groucho Marx

The writer has a grudge against society, which he documents with accounts of unsatisfying sex, unrealized ambition, unmitigated loneliness, and a sense of local and global distress. The square, overpopulation, the bourgeois, the bomb and the cocktail party are variously identified as sources of the grudge. There follows a little obscenity here, a dash of philosophy there, considerable whining overall, and a modern satirical novel is born.
— obscenely quotation by Renata Adler
