One day Alexander the Great asked the philosopher Diogenes why he was sifting through the garbage, Diogenes responded,”I am looking for the bones of your father but I cannot distinguish them from the bones of his slaves.” Also, Alexander the Great asked Diogenes, if there was something he could do for him. Diogenes replied, “yes, get out of my sun”. Plato once defined humans as “featherless bipeds”. Diogenes brought a featherless chicken into Plato’s classroom, saying “Behold! I’ve brought you a man!”
