" It is reported by Diogenes Laertius (VI, 37) that one day, after observing a child drinking out of his hand, Diogenes threw away the cup from his wallet, saying, "A child has given me a lesson in plainness of living." Again, according to Diogenes Laertius (VI, 40), as Diogenes was leaving the public baths, some­ body asked him whether there were many men bathing, to which he answered that there were few people but a large crowd of bathers.
In the example of the child, we have a specific behavioral response­ Diogenes throws away his own cup--and a succinct statement: "A child has given me a lesson in plainness of living." In the second example, we have a terse double reply: Few people were at the baths, but there was a large crowd of bathers. What do we learn from both examples? Plenty indeed, in fact more than we could learn from a treatise on the uselessness of most human inventions and practices, and on the brutal fact, recognized by the Cynics, that most people appear to be human but are not, that is, that most people deceive us into the belief that they are intelligent and decent, while in reality they are nothing but camouflaged rascals and ruffians, and are not therefore truly human. In the first example, Diogenes indicts much of what goes by the name of civilization, and in the second he condemns in no uncertain terms the condition in which most human beings live. "
