| 14235 | Saying 'they can become a set' is a tautology, because reference to 'they' implies a collection [Cargile] |
| Full Idea: If the rule is asserted 'Given any well-determined objects, they can be collected into a set by an application of the 'set of' operation', then on the usual account of 'they' this is a tautology. Collection comes automatically with this form of reference. | |
| From: James Cargile (Paradoxes: Form and Predication [1979], p.115), quoted by Oliver,A/Smiley,T - What are Sets and What are they For? Intro | |
| A reaction: Is this a problem? Given they are well-determined (presumably implying countable) there just is a set of them. That's what set theory is, I thought. Of course, the iterative view talks of 'constructing' the sets, but the construction looks unstoppable. |
| 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. |
| 21994 | The handmill gives feudalism, the steam mill capitalism [Marx] |
| Full Idea: The handmill gives you society with the feudal lord; the steam mill society with the industrial capitalist. | |
| From: Karl Marx (The Poverty of Philosophy [1847], p.202), quoted by Peter Singer - Marx 7 | |
| A reaction: If technology dictates social structure, then feudalism is still with us, in low-tech industries. What if the steam mill had been invented in 1300? |
