Biography:Diogenes was a philosopher born in the 4th century, he was born in Sinope a city in Paphlagonia a country on the coast of the Black Sea and died in c.320 BCE in Corinth a city in Greece living to an age of approximately 90. He is credited as the founder of the philosophical ideal of cynicism. Cynicism stresses the rejection of all luxury and a reliance in self-sufficiency. He lived a life of poverty and homelessness begging for food and sleeping in a large barrel in the Corinthian marketplace.Ideas/Theories:Diogenes conveyed his philosophical ideals through his actions or speech rather than writing or thought unlike other philosophers of the time. For a time his only possession was a wooden bowl until he saw a child drinking with his hands and exclaimed “A child has beaten me inplainess of living” he then threw the bowl away and owned nothing after the bowl. He walked the Corinthian streets holding a lit lantern in the middle of the day when asked what he was doing he stated he was looking for an honest man. Along with the rejection of luxury he also believed that society was superficial and as such the laws and customs of society should be disregarded. He believed that people should be promiscuous and children should be the concern of all. In the marketplace he would perform acts that were considered to be private such as defecating, urinating and masterbating as he believed these to be nescerry bodily functions.Flaws in Ideas:Diogenes belief that organized society, its laws and customs should be disregarded in order to live what he called a “simple life”. Diogenes believed that the lack of organized society would lead to a “natural state” of life were relations were promiscuous and children card for in a communal fashion and parental responsibility were to be shared. The idea that people would revert to a “natural state” when the so called negative effects of society when society is all they know is flawed. Diogenes also disagreed with Plato’s idea of the republic writing a parody starring a so called anarchist utopia. Though an anarchist society may seem perfect all through history one human trait which stays and constant is our self-centered and greedy nature thus such a society is only sustainable in the short term but in the long term a hierarchy almost always forms. Diogenes views on society may have been influenced by how unequal it was at the time. Other philosophers such as Plato perpetuated this class based system by forming the division of society into 3 groups the produces, the army and the rulers and that people should be kept in line by a so called noble lie that people’s value was determined by the metals present in their soul at birth. The idea that being a Cynic incurs you being pro anarchy is unfounded.Other Reasons for Fame:Although Diogenes living choices are linked to his philosophical beliefs they are also a major reason for his ongoing popularity and offers a means of entry to his ideals through stories of his antic. Diogenes was unsatisfied with Plato’s definition of man as a featherless biped (before species such as the kangaroo were discovered), in response Diogenes plucked a chicken and stormed Platonic Academy and declared “behold Plato’s man”. As Diogenes became more notable Alexander the Great came to visit him in his marketplace, upon his visit Alexander offered to grant Diogenes anything he wanted, in response Diogenes who was sunbaking at the time asked him to stop blocking his light. After this request Alexander moved and said to one of his offices “say what you like, but if I were not Alexander, I should like to be diogenes”. These fables offer a way for people to understand some of the key concepts of the Cynic philosophy without having to read confusing texts and help to stop him from fading out of public interest. Lasting contribution:As one of the founders of the Cynic philosophy Diogenes has made a very large impact on the philosophical landscape as they Cynicism helped to refine the ideas of ethics and stressed them as a way to live. Diogenes became a legend in the greek world and though none of his writings are known to still exist he is credited with writing many plays and dialogues. Upon diogenes death statues of him were erected in both Corinth and Sinope.
