What is truth?— Inertia; that hypothesis which gives rise to contentment; smallest expenditure of spiritual force, etc...

The easier mode of thought conquers the harder mode;— as dogma: "simplicity is the seal of truth"— I say: to suppose that clarity proves anything about truth is perfect childishness—

Parmenides said, "one cannot think of what is not";—we are at the other extreme, and say "what can be thought of must certainly be a fiction."

-- Friedrich Nietzsche, The Will to Power (from fragments 537-539)
