“When we suffer anguish we return to early childhood because that is the period in which we first learnt to suffer the experience of total loss. It was more than that. It was the period in which we suffered more total losses than in all the rest of our life put together.”

“But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.”
—Antonin Artaud (1896–1948)
“Jail sentences have many functions, but one is surely to send a message about what our society abhors and what it values.

—Anna Quindlen (b. 1952)
