5 ideas
14617 | Predicates can't apply to what doesn't exist [Stalnaker] |
Full Idea: Nothing can be predicated of something which does not exist. | |
From: Robert C. Stalnaker (Merely Possible Propositions [2010], p.28) | |
A reaction: [He says he is 'agreeing with Plantinga' on this] This seems very puzzling, as you can obviously say that dragons do not exist, but they breathe fire. Why can't you attach predicates to hypothetical objects? |
14616 | A 'Russellian proposition' is an ordered sequence of individual, properties and relations [Stalnaker] |
Full Idea: A 'Russellian proposition' is an ordered sequence containing the individual, along with properties and relations. | |
From: Robert C. Stalnaker (Merely Possible Propositions [2010], p.22) | |
A reaction: Since Russell took properties and relations to be features of reality, this made the whole proposition a feature of reality. This is utterly different from what I understand by the word 'proposition', which is a feature of thought, not of the world. |
11911 | Some philosophers always want more from morality; for others, nature is enough [Blackburn] |
Full Idea: The history of moral theory is largely a history of battles between people who want more (truth, absolutes...) - Plato, Locke, Cudworth, Kant, Nagel - and people content with what we have (nature) - Aristotle, Epicurus, Hobbes, Hume, Stevenson. | |
From: Simon Blackburn (Précis of 'Ruling Passions' [2002], p.133) | |
A reaction: [Thanks to Neil Sinclair for this one] As a devotee of Aristotle, I like this. I'm always impressed, though, by people who go the extra mile in morality, because they are in the grips of purer and loftier ideals than I am. They also turn into monsters! |
1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
Full Idea: Archelaus was the first person to say that the universe is boundless. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
