14592 | Some abstract things have a beginning and end, so may exist in time (though not space) [Swoyer] |
Full Idea: Many things that seem to be abstract also seem to have a beginning (and ending) in time, such as a language like Urdu. It may be tempting to say that such things exist in time but not in space, but where exactly? | |
From: Chris Swoyer (Abstract Entities [2008], 1.1) | |
A reaction: A few distinctions might be needed. Urdu-speaking is an ability of certain people. We abstract from that their 'language'. There is nothing there apart from that ability. It has no more abstract existence than the 'weather'. |
14594 | Ontologists seek existence and identity conditions, and modal and epistemic status for a thing [Swoyer] |
Full Idea: Four things philosophers often want to know about a given sort of entity are: its existence conditions, its identity conditions, its modal status, and its epistemic status. | |
From: Chris Swoyer (Abstract Entities [2008], 3) | |
A reaction: I prefer 'modal profile' to 'modal status'. The 'existence conditions' sound rather epistemic. Why does the existence of anything require 'conditions' other than just existing? I suspect identity is irrelevant if humans aren't around. |
14595 | Can properties exemplify other properties? [Swoyer] |
Full Idea: Can properties themselves exemplify properties? | |
From: Chris Swoyer (Abstract Entities [2008], 3) | |
A reaction: Since I espouse a rather strict causal view of true properties, and lump the rest into the category of 'predicates', I am inclined to answer 'no' to this. Most people would disagree. 'Bright red' seems to be an example. But it isn't. |
14593 | Quantum field theory suggests that there are, fundamentally, no individual things [Swoyer] |
Full Idea: Quantum field theory strongly suggests that there are (at the fundamental level) no individual, particular things. | |
From: Chris Swoyer (Abstract Entities [2008], 2.1) | |
A reaction: When people introduce quantum theory into ontological discussions I reach for my shotgun, but it does rather look as if things turn to mush at the bottom level. |
18284 | Particulars can be verified or falsified, but general statements can only be falsified (conclusively) [Popper] |
Full Idea: Whereas particular reality statements are in principle completely verifiable or falsifiable, things are different for general reality statements: they can indeed be conclusively falsified, they can acquire a negative truth value, but not a positive one. | |
From: Karl Popper (Two Problems of Epistemology [1932], p.256), quoted by J. Alberto Coffa - The Semantic Tradition from Kant to Carnap 18 'Laws' | |
A reaction: This sounds like a logician's approach to science, but I prefer to look at coherence, where very little is actually conclusive, and one tinkers with the theory instead. |
22406 | The maximisation of happiness must be done fairly [Rawls, by Smart] |
Full Idea: Rawls has suggested that we should maximise the general happiness only if we do so in a fair way. | |
From: report of John Rawls (Justice as fairness: Political not Metaphysical [1958]) by J.J.C. Smart - Outline of a System of Utilitarianism 6 | |
A reaction: Rawls is usually seen as an opponent of utilitarianism, but if we allow a few supplementary rules we can improve the theory. After all, it has a meta-rule that 'everybody counts as one'. What other supplementary values can there be? Honesty? |
