Symmetries I 40
Asymmetry/Symmetry: terminology/spelling/Peacocke: red*: property of the visual field - red: property of the object.
red-UV: red* property of the visual field when an (usually different color, so red-UV) object in ultra violet light appears that way. - There is no problem, to define one through the other - being-red can be left out in understanding.
Asymmetry: red/red* can be defined mixed-up, but: red* (visual field) is necessary for the Red-term (of objects), but not vice versa, because red* can be caused by both red and by red-UV objects.
Analogy: different utterances of 'I' can refer to different people, but only one general rule: the reference object is in each case the speaker (> Kaplan: 'Character'). - In the same way red and red-UV have the common character red* (in the visual field).
