>Diogenes made a virtue of poverty. He begged for a living and often slept in a large ceramic jar in the marketplace.
>He became notorious for his philosophical stunts such as carrying a lamp in the daytime, claiming to be looking for an honest man.
>Diogenes looked for a human being but reputedly found nothing but rascals and scoundrels.
>He criticized and embarrassed Plato, disputed his interpretation of Socrates and sabotaged his lectures, sometimes distracting attendees by bringing food and eating during the discussions.
>When Plato gave Socrates's definition of man as "featherless bipeds" and was much praised for the definition, Diogenes plucked a chicken and brought it into Plato's Academy, saying, "Behold! I've brought you a man." After this incident, "with broad flat nails" was added to Plato's definition.[26]
>Diogenes was also noted for having publicly mocked Alexander the Great.[5][6][7]
>Alexander found the philosopher looking attentively at a pile of human bones. Diogenes explained, "I am searching for the bones of your father but cannot distinguish them from those of a slave."[34]
>Diogenes is said to have eaten in the marketplace,[47] urinated on some people who insulted him,[48] defecated in the theatre,[49] and masturbated in public. [50] On the indecency of his masturbating in public he would say, "If only it were as easy to banish hunger by rubbing my belly."[51][52]
