4 ideas
2118 | All other human gifts can harm us, but not correct reasoning [Leibniz] |
Full Idea: Although people can be made worse off by all other gifts, correct reasoning alone can only be for the good. | |
From: Gottfried Leibniz (Preface to Universal Characteristic [1679]) | |
A reaction: How about a kind heart? Not everyone would agree with the remark, but philosophers should. |
10245 | One geometry cannot be more true than another [Poincaré] |
Full Idea: One geometry cannot be more true than another; it can only be more convenient. | |
From: Henri Poincaré (Science and Method [1908], p.65), quoted by Stewart Shapiro - Philosophy of Mathematics | |
A reaction: This is the culminating view after new geometries were developed by tinkering with Euclid's parallels postulate. |
2854 | Prescriptivism says 'ought' without commitment to act is insincere, or weakly used [Hooker,B] |
Full Idea: Prescriptivism holds that if you think one 'ought' to do a certain kind of act, and yet you are not committed to doing that act in the relevant circumstances, then you either spoke insincerely, or are using the word 'ought' in a weak sense. | |
From: Brad W. Hooker (Prescriptivism [1995], p.640) | |
A reaction: So that's an 'ought', but not a 'genuine ought', then? (No True Scotsman move). Someone ought to rescue that drowning child, but I can't be bothered. |
2856 | Universal moral judgements imply the Golden Rule ('do as you would be done by') [Hooker,B] |
Full Idea: Prescriptivity is especially important if moral judgements are universalizable, for then we can employ golden rule-style reasoning ('do as you would be done by'). | |
From: Brad W. Hooker (Prescriptivism [1995], p.640) |
