6860 | How can one discriminate yellow from red, but not the colours in between? [Williamson] |
Full Idea: If one takes a spectrum of colours from yellow to red, it might be that given a series of colour samples along that spectrum, each sample is indiscriminable by the naked eye from the next one, though samples at either end are blatantly different. | |
From: Timothy Williamson (Interview with Baggini and Stangroom [2001], p.151) | |
A reaction: This seems like a nice variant of the Sorites paradox (Idea 6008). One could demonstrate it with just three samples, where A and C seemed different from each other, but other comparisons didn't. |
