Diogenes placed reason and nature firmly above custom and convention, which he held to be incompatible with happiness. It is natural for a human being to act in accord with reason, and reason dictates that a human being should live in accord with nature. Accordingly, he taught that, if an act is not shameful in private, then it should not be shameful in public either. Upon being challenged for masturbating in the marketplace, he replied, ‘If only it were so easy to soothe hunger by rubbing an empty belly’. Upon being asked, on another occasion, where he came from, he replied, ‘I am a citizen of the world’ (cosmopolites), a radical claim at the time and the first recorded use of the term ‘cosmopolitan’. Although Diogenes privileged reason, he despised the sort of abstract philosophy that was being practiced elsewhere and in particular at Plato’s Academy. When, to great acclaim, Plato defined a human being as an animal, biped, and featherless, Diogenes plucked a fowl and brought it to the Academy with the words, ‘Behold! I have brought you Plato’s man.’ Plato consequently revised his definition, adding to it ‘with broad nails’.
Diogenes was not impressed with his fellow men, not even with Alexander the Great, who came to meet him one morning while he was lying in the sunlight. When Alexander asked him whether there was any favour he might do for him, he replied, ‘Yes, stand out of my sunlight.’ Much to his credit, Alexander still declared, ‘If I were not Alexander, then I should wish to be Diogenes.’ In another account of the conversation, Alexander found Diogenes looking attentively at a pile of human bones. Diogenes explained, ‘I am searching for the bones of your father (King Philip of Macedon), but cannot distinguish them from those of a slave.’ Diogenes used to stroll about in broad daylight with a lamp. Whenever curious people asked him what he was doing, he would reply, ‘I am just looking for a human being.’ Much to his chagrin, all he ever found were rascals and scoundrels. When asked how he wished to be buried, he left instructions to be thrown outside the city wall so that wild animals could feast upon his body. After his death in the city of Corinth, the Corinthians erected to his memory a pillar upon which they rested a dog of Parian marble. Diogenes taught by living example that wisdom and happiness belong to the person who is independent of society. He was, I think, a shining example of the art of failure.
