List of Famous people named Diogenes

Diogenes, also known as Diogenes the Cynic, was a Greek philosopher and one of the founders of Cynic philosophy. He was born in Sinope, an Ionian colony on the Black Sea coast of modern-day Turkey, in 412 or 404 BC and died at Corinth in 323 BC.

Diógenes da Silva Matthes was a Roman Catholic bishop.

Diogenes of Babylon was a Stoic philosopher. He was the head of the Stoic school in Athens, and he was one of three philosophers sent to Rome in 155 BC. He wrote many works, but none of his writings survive, except as quotations by later writers.

Diogenes Laërtius was a biographer of the Greek philosophers. Nothing is definitively known about his life, but his surviving Lives and Opinions of Eminent Philosophers is a principal source for the history of ancient Greek philosophy. His reputation is controversial among scholars because he often repeats information from his sources without critically evaluating it. He also frequently focuses on trivial or insignificant details of his subjects' lives while ignoring important details of their philosophical teachings and he sometimes fails to distinguish between earlier and later teachings of specific philosophical schools. However, unlike many other ancient secondary sources, Diogenes Laërtius generally reports philosophical teachings without attempting to reinterpret or expand on them, which means his accounts are often closer to the primary sources. Due to the loss of so many of the primary sources on which Diogenes relied, his work has become the foremost surviving source on the history of Greek philosophy.
