My feeling for other life on the planet isn't objective either, nor would I want it to be. But I do still "seek to achieve a completely objective relationship to reality in the natural world", as I said, which is not quite the same thing.
One can't be scientific without an objective relationship to reality, I think. Dreaming and being emotional is all very well in certain circumstances. I'm not knocking it where it's appropriate, but reality is reality is reality whatever one's feelings about anything, so while one can feel sadness at the loss of a tree species, or whatever, one can also, at the same time, know that extinctions happen whether we like it or not, and indeed happened in extremely large doses before we even existed, and one can give a shrug because of that.
