Diogenes for the Day, 7/21/2018

The man had in fact a wonderful gift of persuasion, so that he could easily vanquish anyone he liked in argument. 

At all events a certain Onesicritus of Aegina is said to have sent to Athens the one of his two sons named Androsthenes, and he having become a pupil of Diogenes stayed there. 

The father then sent the other also, the aforesaid Philiscus, who was the elder, in search of him, but Philiscus also was detained in the same way. 

When, thirdly, the father himself arrived, he was just as much attracted to the pursuit of philosophy as his sons and joined the circle—so magical was the spell that the discourses of Diogenes exerted. 

Among his hearers was Phocion, surnamed the Honest, and Stilpo the Megarian, and many other men prominent in political life.
