| 9254 | In philosophy the truth can only be reached via the ruins of the false [Prichard] |
| Full Idea: In philosophy the truth can only be reached via the ruins of the false. | |
| From: H.A. Prichard (What is the Basis of Moral Obligation? [1925]) | |
| A reaction: A lovely remark! In a flash you suddenly see why philosophers expend such vast energy on such unpromising views of reality (e.g. idealism, panpsychism). This might be the best definition of philosophy I have yet discovered. |
| 9390 | Logic guides thinking, but it isn't a substitute for it [Rumfitt] |
| Full Idea: Logic is part of a normative theory of thinking, not a substitute for thinking. | |
| From: Ian Rumfitt (The Logic of Boundaryless Concepts [2007], p.13) | |
| A reaction: There is some sort of logicians' dream, going back to Leibniz, of a reasoning engine, which accepts propositions and outputs inferences. I agree with this idea. People who excel at logic are often, it seems to me, modest at philosophy. |
| 9389 | Vague membership of sets is possible if the set is defined by its concept, not its members [Rumfitt] |
| Full Idea: Vagueness in respect of membership is consistency with determinacy of the set's identity, so long as a set's identity is taken to consist, not in its having such-and-such members, but in its being the extension of a concept. | |
| From: Ian Rumfitt (The Logic of Boundaryless Concepts [2007], p.5) | |
| A reaction: I find this view of sets much more appealing than the one that identifies a set with its members. The empty set is less of a problem, as well as non-existents. Logicians prefer the extensional view because it is tidy. |
| 9256 | I see the need to pay a debt in a particular instance, and any instance will do [Prichard] |
| Full Idea: How can I be brought to see the truth of the principle of paying a debt except in connection with a particular instance? For this purpose any instance will do. If I cannot see that I ought to pay this debt, I shall not see that I ought to a debt. | |
| From: H.A. Prichard (What is the Basis of Moral Obligation? [1925]) | |
| A reaction: This isn't quite particularism, which would (I think) say that the degree of obligation will never be quite the same in any two situations, and so one instance will not suffice to understand the duty. |
| 9257 | The complexities of life make it almost impossible to assess morality from a universal viewpoint [Prichard] |
| Full Idea: Owing to the complication of human relations, the problem of what one ought to do from the point of view of life as a whole is one of intense difficulty. | |
| From: H.A. Prichard (What is the Basis of Moral Obligation? [1925]) | |
| A reaction: I suspect that the difficulty is not the problems engendered by complexity, but that there is no answer available from the most objective point of view. Morality simply is a matter of how daily life is conducted, with medium-term goals only. |
| 9255 | Seeing the goodness of an effect creates the duty to produce it, not the desire [Prichard] |
| Full Idea: The appreciation of the goodness of the effect is different from desire for the effect, and will originate not the desire but the sense of obligation to produce it. | |
| From: H.A. Prichard (What is the Basis of Moral Obligation? [1925]) | |
| A reaction: A wonderful rebuttal of Hume, and a much better account of duty than Kant's idea that it arises from reason. Perception of value is what generates duty. And (with Frankfurt) we may say that love is what generates value. |
| 1474 | Moral evil may be acceptable to God because it allows free will (even though we don't see why this is necessary) [Plantinga, by PG] |
| Full Idea: Moral evil may be acceptable to a benevolent God because it is the only way to allow genuine free will, which may have a supreme value in creation (even if we are unsure what it is). | |
| From: report of Alvin Plantinga (Free Will Defence [1965], Pref.) by PG - Db (ideas) |
| 1475 | It is logically possible that natural evil like earthquakes is caused by Satan [Plantinga, by PG] |
| Full Idea: Physical evil (e.g. earthquakes) may be attributable to a fallen angel (Satan), who is the enemy of God, and this is enough to retain the idea that God is omnipotent and benevolent, and yet evil exists. | |
