Thinking is man’s only basic virtue, from which all the others proceed. And his
basic vice, the source of all his evils, is that nameless act which all of you
practice, but struggle never to admit: the act of blanking out, the willful
suspension of one’s consciousness, the refusal to think—not blindness, but the
refusal to see; not ignorance, but the refusal to know. It is the act of
unfocusing your mind and inducing an inner fog to escape the responsibility of
judgment—on the unstated premise that a thing will not exist if only you
refuse to identify it, that A will not be A so long as you do not pronounce the
verdict “It is.”
