There is no escape from this dilemma. Even Lao Tzu, who wrote, "He who knows speaks not. He who speaks knows not," falsified his own assertion by writing the few thousand words with which he composed the Tao Teh Ching. Hence the philosopher is not committed either to silence or to speech. In the Absolute, both are the same. Lao Tzu's celebrated phrase would have held more correctness and less exaggeration if it had been slightly modified to read: "He who speaks, may not know. He who knows, may not freely speak."
