[catalogued under 2. Reason / D. Definition / 11. Ostensive Definition]

Full Idea

Is it true that we cannot say, non-circularly, what red is? We cannot find a complex synonym for it, but I think we can provide red with an ostensive real definition.

Gist of Idea

Simple things like 'red' can be given real ostensive definitions

A Reaction

I'm not quite sure how 'real' this definition would be, if it depends on observers (some of whom may be colourblind). In what sense is this act of ostensions a 'definition'? You must distinguish the colour from the texture or shape.
