7566 | The Identity of Indiscernibles is really the same as the verification principle [Jolley] |
Full Idea: Various writers have noted that the Identity of Indiscernibles is really tantamount to the verification principle. | |
From: Nicholas Jolley (Leibniz [2005], Ch.3) | |
A reaction: Both principles are false, because they are the classic confusion of epistemology and ontology. The fact that you cannot 'discern' a difference between two things doesn't mean that there is no difference. Things beyond verification can still be discussed. |
7296 | 'Grue' is not a colour [Milsted] |
Full Idea: 'Grue' is not a colour. | |
From: Tom Milsted (talk [2006]), quoted by PG - Db (ideas) | |
A reaction: This simple observation strikes me as rather crucial in assessing Goodman's paradox. Blue is a colour, but grue is some sort of behaviour. Blue is a secondary quality, but grue seems to be a primary quality. |
20653 | Six reduction levels: groups, lives, cells, molecules, atoms, particles [Putnam/Oppenheim, by Watson] |
Full Idea: There are six 'reductive levels' in science: social groups, (multicellular) living things, cells, molecules, atoms, and elementary particles. | |
From: report of H.Putnam/P.Oppenheim (Unity of Science as a Working Hypothesis [1958]) by Peter Watson - Convergence 10 'Intro' | |
A reaction: I have the impression that fields are seen as more fundamental that elementary particles. What is the status of the 'laws' that are supposed to govern these things? What is the status of space and time within this picture? |
