“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)
“Passionate love, I take it, rarely lasts long, and is very troublesome while it does last. Mutual esteem is very much more valuable.”
