| 14361 | Lewis says indicative conditionals are truth-functional [Lewis, by Jackson] |
| Full Idea: Unlike Stalnaker, Lewis holds that indicative conditionals have the truth conditions of material conditionals. | |
| From: report of David Lewis (Counterfactuals [1973]) by Frank Jackson - Conditionals 'Further' | |
| A reaction: Thus Lewis only uses the possible worlds account for subjunctive conditionals, where Stalnaker uses it for both. Lewis is defending the truth-functional account for the indicative conditionals. |
| 8434 | In good counterfactuals the consequent holds in world like ours except that the antecedent is true [Lewis, by Horwich] |
| Full Idea: According to Lewis, a counterfactual holds when the consequent is true in possible worlds very like our own except for the fact that the antecedent is true. | |
| From: report of David Lewis (Counterfactuals [1973]) by Paul Horwich - Lewis's Programme p.213 | |
| A reaction: Presumably the world being very like our own would make it unlikely that there would be anything else to cause the consequent, apart from the counterfactual antecedent. |
| 20166 | A man is a responsible agent to the extent he has an intention, and knows what he is doing [Hampshire] |
| Full Idea: A man becomes more and more a free and responsible agent the more he at all times knows what he is doing, in every sense of this phrase, and the more he acts with a definite and clearly formed intention. | |
| From: Stuart Hampshire (Thought and Responsibility [1960], p.178), quoted by John Kekes - The Human Condition 07.1 | |
| A reaction: Kekes quote this (along with Frankfurt, Hart etc) as the 'received view' of responsibility, which he attacks. |
| 5845 | Niceratus learnt the whole of Homer by heart, as a guide to goodness [Xenophon] |
| Full Idea: Niceratus said that his father, because he was concerned to make him a good man, made him learn the whole works of Homer, and he could still repeat by heart the entire 'Iliad' and 'Odyssey'. | |
| From: Xenophon (Symposium [c.391 BCE], 3.5) | |
| A reaction: This clearly shows the status which Homer had in the teaching of morality in the time of Socrates, and it is precisely this acceptance of authority which he was challenging, in his attempts to analyse the true basis of virtue |
| 9419 | A law of nature is a general axiom of the deductive system that is best for simplicity and strength [Lewis] |
| Full Idea: A contingent generalization is a law of nature if and only if it appears as a theorem (or axiom) in each of the true deductive systems that achieves a best combination of simplicity and strength. | |
| From: David Lewis (Counterfactuals [1973], 3.3) |
