9 ideas
| 7823 | Lucretius was rediscovered in 1417 [Grayling] |
| Full Idea: Lucretius's 'De Rerum Natura' was rediscovered in 1417, after languishing forgotten for six centuries. | |
| From: A.C. Grayling (What is Good? [2003], Ch.5) | |
| A reaction: A wonder. Is it the greatest book of the ancient world - because it partially preserves the lost philosophy of great Democritus? |
| 17447 | Parsons says counting is tagging as first, second, third..., and converting the last to a cardinal [Parsons,C, by Heck] |
| Full Idea: In Parsons's demonstrative model of counting, '1' means the first, and counting says 'the first, the second, the third', where one is supposed to 'tag' each object exactly once, and report how many by converting the last ordinal into a cardinal. | |
| From: report of Charles Parsons (Frege's Theory of Numbers [1965]) by Richard G. Heck - Cardinality, Counting and Equinumerosity 3 | |
| A reaction: This sounds good. Counting seems to rely on that fact that numbers can be both ordinals and cardinals. You don't 'convert' at the end, though, because all the way you mean 'this cardinality in this order'. |
| 3583 | External objects are permanent possibilities of sensation [Mill] |
| Full Idea: External objects are permanent possibilities of sensation. | |
| From: John Stuart Mill (Examination of Sir Wm Hamilton's Philosophy [1865]), quoted by Michael Williams - Problems of Knowledge Ch.9 |
| 3537 | I judge others' feeling by analogy with my body and behaviour [Mill] |
| Full Idea: I conclude other humans have feelings like me because they have bodies like mine (which I know in my case to be antecedent to feelings), and because they exhibit acts and outwards signs which I know in my own case to be caused by feelings. | |
| From: John Stuart Mill (Examination of Sir Wm Hamilton's Philosophy [1865], p.243), quoted by Keith T. Maslin - Introduction to the Philosophy of Mind 8.2 | |
| A reaction: It is hard to see anything further that can be added to the 'other minds' question. Behaviour is highly relevant (imagine meeting a human who talked like a robot), but so are bodies (imagine a tin box that talked like Marilyn Monroe). |
| 7809 | In an honour code shame is the supreme punishment, and revenge is a duty [Grayling] |
| Full Idea: An honour code is one in which the greatest punishment is shame, and in which revenge is a duty. | |
| From: A.C. Grayling (What is Good? [2003], Ch.2) | |
| A reaction: Is this really what Nietzsche wanted to revive? Shame isn't a private matter - it needs solidarity of values in the community, and contempt for dishonour, so that it becomes everyone's worst fear. |
| 7824 | If suicide is lawful, but assisting suicide is unlawful, powerless people are denied their rights [Grayling] |
| Full Idea: An anomaly created by England's 1961 Suicide Act is that it is lawful to take one's own life, but unlawful to help anyone else to do it. This means anyone unable to commit suicide without help is denied one of their fundamental rights. | |
| From: A.C. Grayling (What is Good? [2003], Ch.8) | |
| A reaction: There is a difference, not really captured either by law or by reason, between tolerating an activity, and encouraging and helping it. I think the test question is "this activity is legal, but would you want your child to do it?" |
| 7819 | Religion gives answers, comforts, creates social order, and panders to superstition [Grayling] |
| Full Idea: The four standard explanations given for religion are that it provides answer, that it gives comfort, that it makes for social order, and that it rests on mere superstition. | |
| From: A.C. Grayling (What is Good? [2003], Ch.4) | |
| A reaction: All four of these could be correct, though the first and fourth would be incompatible if religion gives correct answers. Why religion begins might be not the same as the reason why it continues. |
| 7817 | To make an afterlife appealing, this life has to be denigrated [Grayling] |
| Full Idea: It is remarkable how much the life of this world has to be denigrated to make the promise of happiness after death appealing. | |
| From: A.C. Grayling (What is Good? [2003], Ch.4) | |
| A reaction: This seems to be true of most religions, but it could be otherwise. Surely you want such a wonderful life to continue after death? But then you would not be obliged to do anything difficult to achieve immortality. Power comes into it... |
| 7818 | In Greek mythology only heroes can go to heaven [Grayling] |
| Full Idea: In Greek mythology only a hero like Hercules could hope to go to heaven (by becoming a god himself). | |
| From: A.C. Grayling (What is Good? [2003], Ch.4) | |
| A reaction: This illustrates Nietsche's 'inversion of morality' most clearly, because Christianity says that the person most likely to go to heaven is the humblest person. |
