green numbers give full details    |    back to list of philosophers    |     unexpand these ideas    |    
1. Philosophy / D. Nature of Philosophy / 2. Invocation to Philosophy
Diogenes said avoidance of philosophy is the lack of a desire to live properly
     Full Idea: When a man said that he was not suited to philosophy, Diogenes said to him, 'Why then do you live, if you have no desire to live properly.'
     From: report of Diogenes (Sin) (reports [c.360 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 06.Di.6
     A reaction: Meaning philosophy is already more practice than theory.
13. Knowledge Criteria / D. Scepticism / 6. Scepticism Critique
When someone denied motion, Diogenes got up and walked away
     Full Idea: Diogenes replied to one who asserted that there was no such thing as motion by getting up and walking away.
     From: report of Diogenes (Sin) (reports [c.360 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 06.Di.6
20. Action / C. Motives for Action / 3. Acting on Reason / b. Intellectualism
Cynicism was open to anyone, and needed neither education nor sophistication
     Full Idea: An advantage of Cynicism was that it was open to anyone who could grasp its simple teachings. Understanding it required neither education nor sophistication.
     From: report of Diogenes (Sin) (reports [c.360 BCE]) by A.C. Grayling - What is Good? Ch.3
     A reaction: This was the source of the well-known opposition of Diogenes to Plato's Academy, and it makes him a key predecessor of the teachings of Jesus. Personally I think the really good life is difficult, and it needs education and careful rational thought.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / e. Human nature
Diogenes said a plucked chicken fits Plato's definition of man
     Full Idea: Plato defined man as a two-footed featherless animal, so Diogenes plucked a cock and brought it into the school, and said, 'This is Plato's man'.
     From: report of Diogenes (Sin) (reports [c.360 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 06.Di.6
     A reaction: You have to be very serious about your philosophy to enact your counterexamples, rather than just suggest them. Which university will actually reconstruct the Trolley Problem?
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / j. Ethics by convention
The Cynics rejected what is conventional as irrational, and aimed to live by nature
     Full Idea: The Cynics were convinced of the purely conventional foundation of Athenian values, which meant they had no rational foundation at all. They therefore rejected them in favour of what is correct and worthwhile by nature.
     From: comment on Diogenes (Sin) (reports [c.360 BCE]) by Richard Taylor - Virtue Ethics: an Introduction Ch.8
     A reaction: This shows how the Cynics are key players in the progress of the nomos-physis debate, which keeps resurfacing as relativism vs absolutism, cognitivism vs non-cognitivism, and even romanticism vs classicism. The trouble is, convention is natural!
22. Metaethics / C. The Good / 2. Happiness / d. Routes to happiness
For peace of mind, you need self-government, indifference and independence
     Full Idea: There are three essential conditions for peace of mind: autarchy, apathy and freedom. Autarchy is self-government and self-sufficiency; apathy is indifference to what the world can do to you; the freedom is from dependence and possessions.
     From: Diogenes (Sin) (reports [c.360 BCE]), quoted by A.C. Grayling - What is Good? Ch.3
     A reaction: Quite good advice, but I don't see 'peace of mind' as the highest human ideal. The basic suggestion here is live alone and do nothing. Certainly don't get married, or have children, or try to achieve anything.
24. Political Theory / B. Nature of a State / 4. Citizenship
Diogenes said he was a citizen of the world
     Full Idea: Diogenes said he was a citizen of no country, but of the world.
     From: report of Diogenes (Sin) (reports [c.360 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 06.Di.6
24. Political Theory / D. Ideologies / 2. Anarchism
Diogenes masturbated in public, wishing he could get rid of hunger so easily
     Full Idea: Chrysippus praises Diogenes for saying to bystanders as he masturbated in public, "Would that I could thus rub the hunger too out of my belly".
     From: report of Diogenes (Sin) (reports [c.360 BCE]) by Plutarch - 70: Stoic Self-contradictions 1044b
     A reaction: So it is not quite true that people only need corn and water. Diogenes' remark doesn't explain why he did it in public. Was it to defy local convention (as befits a citizen of the world), or was it to teach?
25. Social Practice / A. Freedoms / 3. Free speech
Diogenes said that the most excellent thing among men was freedom of speech
     Full Idea: Diogenes said that the most excellent thing among men was freedom of speech.
