[nefitty]

I see what you mean. I took it for granted that it's clear that sentience is a prerequisite to the capability of having desires. If someone did argue that plants have desires then I would question what they mean: either they're implying conscious preference of future states, desire predicated on sentience or they mean some metaphysical teleological conception of desire. The first two are mistakes, the last is not really the type of argument that I find fascinating beyond its relevance to social ritual or linguistic games.
