| 14248 | We could accept the integers as primitive, then use sets to construct the rest [Cohen] |
| Full Idea: A very reasonable position would be to accept the integers as primitive entities and then use sets to form higher entities. | |
| From: Paul J. Cohen (Set Theory and the Continuum Hypothesis [1966], 5.4), quoted by Oliver,A/Smiley,T - What are Sets and What are they For? | |
| A reaction: I find this very appealing, and the authority of this major mathematician adds support. I would say, though, that the integers are not 'primitive', but pick out (in abstraction) consistent features of the natural world. |
| 5126 | A carelessly thrown brick is condemned much more if it hits someone [Smith,A, by Harman] |
| Full Idea: Adam Smith wrote about the influence of fortune on moral judgements, giving nice examples. Someone carelessly throws a brick over a wall. His companion may complain even if no harm is done. But if the brick hits someone much greater condemnation ensues. | |
| From: report of Adam Smith (The Theory of Moral Sentiments [1759]) by Gilbert Harman - Moral Philosophy meets social psychology 10.7.1.2 | |
| A reaction: This appears to be the earliest observation of the phenomenon of moral luck, though Plato (Idea 269) endorsed the view that the luck of outcome should be taken into account in moral judgements. |
| 20991 | People prepare our dinner from their own self-interest, not from humanity [Smith,A] |
| Full Idea: It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own interest. We address ourselves, not to their humanity but to their self-love. | |
| From: Adam Smith (The Wealth of Nations [1776], p.26-7), quoted by Amartya Sen - The Idea of Justice 08 'Narrowing' | |
| A reaction: Sen passionately pleads that this not be taken out of context. It is about the motivation for the relationship of exchange, and not about morality in general, which also includes trust etc. The subsequent lines in Smith show this. |
| 20680 | Selfish profit-seeking increases collective wealth, so greed is good, and egoism is altruism [Smith,A, by Harari] |
| Full Idea: Smith's claim that the selfish human urge to increase private profits is the basis for collective wealth is one of the most revolutionary ideas in human history. …Greed is good …and egoism is altruism. | |
| From: report of Adam Smith (The Wealth of Nations [1776]) by Yuval Noah Harari - Sapiens: brief history of humankind 16 'Growing' | |
| A reaction: The central confrontation of political philosophy still seems to be Adam Smith v Karl Marx. Why can't there be altruistic non-greedy profit-seeking? Not 'I want profits' but 'we want profits'. Altruistic capitalists aim to create jobs. |
| 3029 | Stilpo said if Athena is a daughter of Zeus, then a statue is only the child of a sculptor, and so is not a god [Stilpo, by Diog. Laertius] |
| Full Idea: Stilpo asked a man whether Athena is the daughter of Zeus, and when he said yes, said,"But this statue of Athena by Phidias is the child of Phidias, so it is not a god." | |
| From: report of Stilpo (fragments/reports [c.330 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.10.5 |
