There are many marvellous stories told of Pherecydes. For it is said that he was walking along the seashore at Samos, and that seeing a ship sailing by with a fair wind, he said that it would soon sink; and presently it sank before his eyes. At another time he was drinking some water which had been drawn up out of a well, and he foretold that within three days there would be an earthquake; and there was one.
Diogenes LaertiusOne of the sayings of Diogenes was that most men were within a finger's breadth of being mad; for if a man walked with his middle finger pointing out, folks would think him mad, but not so if it were his forefinger.
