Full Idea
Because the wind is cold to me but not you, Protagoras takes it to in itself neither cold nor not-cold. Accordingly, I very much doubt that he can allow the wind to be exactly as cold as itself.
Gist of Idea
If my hot wind is your cold wind, then wind is neither hot nor cold, and so not as cold as itself
