16 ideas

2. Reason / C. Styles of Reason / 1. Dialectic
Dialectic involves conversations with short questions and brief answers [Diog. Laertius]
     Full Idea: Dialectic is when men converse by putting short questions and giving brief answers to those who question them.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 3.1.52)
3. Truth / E. Pragmatic Truth / 1. Pragmatic Truth
Does the pragmatic theory of meaning support objective truth, or make it impossible? [Macbeth]
     Full Idea: Peirce and Sellars takes Peirce's conception of meaning, on which pragmatism is founded, to support an adequate account of objective truth; James, Dewey and Rorty say it forecloses all possibility of such an account.
     From: Danielle Macbeth (Pragmatism and Objective Truth [2007], p.169)
     A reaction: Ah. Very helpful. I thought there was a pragmatic theory of truth, then began to think that it was just a denial of truth. I've long suspected that Peirce is wonderful, and James is not very good (on this topic).
5. Theory of Logic / A. Overview of Logic / 5. First-Order Logic
Classical liberalism seeks freedom of opinion, of private life, of expression, and of property [Micklethwait/Wooldridge]
     Full Idea: The classical liberals agreed on a basic list of freedoms: of opinion (including religion), of private life, of expression, and of property
     From: Micklethwait,J/Wooldridge,A (The Fourth Revolution [2014], 9)
     A reaction: Mill is main articulator of this. Modern neo-liberals focus on economic freedom. Neither of them seem to make freedom of opportunity central, though I suspect our modern Liberal Party would.
6. Mathematics / B. Foundations for Mathematics / 5. Definitions of Number / b. Greek arithmetic
Greek mathematics is wholly sensory, where ours is wholly inferential [Macbeth]
     Full Idea: Ancient mathematical concepts were essentially sensory; they were not mathematical in our sense - that is, wholly constituted by their inferential potential.
     From: Danielle Macbeth (Pragmatism and Objective Truth [2007], p.187)
     A reaction: The latter view is Frege's, though I suppose it had been emerging for a couple of centuries before him. I like the Greek approach, and would love to see that reunited with the supposedly quite different modern view. (Keith Hossack is attempting it).
13. Knowledge Criteria / A. Justification Problems / 2. Justification Challenges / a. Agrippa's trilemma
Sceptics say demonstration depends on self-demonstrating things, or indemonstrable things [Diog. Laertius]
     Full Idea: Sceptics say that every demonstration depends on things which demonstrates themselves, or on things which can't be demonstrated.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 9.Py.11)
     A reaction: This refers to two parts of Agrippa's Trilemma (the third being that demonstration could go on forever). He makes the first option sound very rationalist, rather than experiential.
13. Knowledge Criteria / D. Scepticism / 1. Scepticism
Scepticism has two dogmas: that nothing is definable, and every argument has an opposite argument [Diog. Laertius]
     Full Idea: Sceptics actually assert two dogmas: that nothing should be defined, and that every argument has an opposite argument.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 9.Py.11)
13. Knowledge Criteria / D. Scepticism / 6. Scepticism Critique
When sceptics say that nothing is definable, or all arguments have an opposite, they are being dogmatic [Diog. Laertius]
     Full Idea: When sceptics say that they define nothing, and that every argument has an opposite argument, they here give a positive definition, and assert a positive dogma.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 9.11.11)
14. Science / B. Scientific Theories / 1. Scientific Theory
Seeing reality mathematically makes it an object of thought, not of experience [Macbeth]
     Full Idea: As mathematically understood, the world is not an object of experience but instead an object of thought.
     From: Danielle Macbeth (Pragmatism and Objective Truth [2007], p.183)
     A reaction: Since I am keen on citing biology to show that science does not have to be mathematical, this nicely shows that there is something wrong with a science which places a large gap between itself and the world.
14. Science / C. Induction / 4. Reason in Induction
Induction moves from some truths to similar ones, by contraries or consequents [Diog. Laertius]
     Full Idea: Induction is an argument which by means of some admitted truths establishes naturally other truths which resemble them; there are two kinds, one proceeding from contraries, the other from consequents.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 3.1.23)
18. Thought / D. Concepts / 1. Concepts / a. Nature of concepts
For pragmatists a concept means its consequences [Macbeth]
     Full Idea: In the pragmatist view, the meaning of a concept is exhausted by its consequences.
     From: Danielle Macbeth (Pragmatism and Objective Truth [2007], p.173)
     A reaction: I'm unclear why the concept of a volcanic eruption only concerns its dire consequences, and is supposed to contain nothing of its causes. Pragmatists seem to be all future, and no past. Very American.
22. Metaethics / C. The Good / 3. Pleasure / b. Types of pleasure
Cyrenaic pleasure is a motion, but Epicurean pleasure is a condition [Diog. Laertius]
     Full Idea: Cyrenaics place pleasure wholly in motion, whereas Epicurus admits it as a condition.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 10.28)
     A reaction: Not a distinction we meet in modern discussions. Do events within the mind count as 'motion'? If so, these two agree. If not, I'd vote for Epicurus.
23. Ethics / A. Egoism / 1. Ethical Egoism
Cynics believe that when a man wishes for nothing he is like the gods [Diog. Laertius]
     Full Idea: Cynics believe that when a man wishes for nothing he is like the gods.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 6.Men.3)
24. Political Theory / D. Ideologies / 8. Socialism
The welfare state aims at freedom from want, and equality of opportunity [Micklethwait/Wooldridge]
     Full Idea: In the classical liberal tradition freedom meant freedom from external control, and equality meant equality before the law. In the welfare state (of Beatrice Webb) freedom was reinterpreted as freedom from want, and equality as equality of opportunity.
     From: Micklethwait,J/Wooldridge,A (The Fourth Revolution [2014], 3)
     A reaction: The authors call this the 'third revolution' in government, after 17th century centralisation and early 19th century accountability. Tawney 1931 is the key text.
24. Political Theory / D. Ideologies / 9. Communism
For communists history is driven by the proletariat [Micklethwait/Wooldridge]
     Full Idea: For the communists the proletariat rather than the state was the locomotive of history.
     From: Micklethwait,J/Wooldridge,A (The Fourth Revolution [2014], 3)
     A reaction: I feel increasingly reluctant to support any party which appears to mainly represent the interests of a single social class, no matter how large that class may be. An attraction of liberalism is that it makes no reference to class.
24. Political Theory / D. Ideologies / 11. Capitalism
Fans of economic freedom claim that capitalism is self-correcting [Micklethwait/Wooldridge]
     Full Idea: The central laissez-faire conceit is that capitalism is a self-correcting mechanism.
     From: Micklethwait,J/Wooldridge,A (The Fourth Revolution [2014], 3)
     A reaction: This was Keynes's rather left-wing criticism of standard capitalist views. These resurfaced in the 1980s with mantras about the virtues of 'market forces'.
25. Social Practice / C. Rights / 4. Property rights
Roman law entrenched property rights [Micklethwait/Wooldridge]
     Full Idea: Roman law entrenched property rights.
     From: Micklethwait,J/Wooldridge,A (The Fourth Revolution [2014], 1 Intro)
     A reaction: Normally attributed to Locke, so this is a good corrective. Was the principle gradually forgotten before Locke?
