Quote of the day

"Physical" is not the only criterion of truth: there are also psychic truths which neither be explained nor proved nor contested in any physical way. If, for instance, a general belief existed that the river Rhine had at one time flowed backwards from its mouth to its source, then this belief would be itself a fact even though such an assertion, physically understood, would be deemed utterly incredible. Beliefs of this kind are psychic facts which cannot be contested and need no proof. CW 11 - par 553
