“It’s the old captain’s dark fate
Who failed to find or force a strait
In its two-thousand-mile coast;
And his crew left him where he failed,
And nothing came of all he sailed.”
—Robert Frost (1874–1963)
“Intellectual despair results in neither weakness nor dreams, but in violence.... It is only a matter of knowing how to give vent to one’s rage; whether one only wants to wander like madmen around prisons, or whether one wants to overturn them.”
—Georges Bataille (1897–1962)
