Utilitarianism = contrived word meaning what is best for the organism as a whole, suggesting that at least man, if not all living plants and beasts are part of that same organism.
I.E., discard what is useless to the organism as a whole, or does not contribute back to the organism, that being in Singer's model, life on earth in general.
When I was pregnant with my first baby some lots of years ago, I was sick...very ill...for 8.5 months. I had to have intravenous fluids because I was so dehydrated. According to Singer I was a useless eater (though I couldn't eat) for 8.5 months. My offspring in his maturity became a productive adult and provided me 3 beautiful little grandsons.
Singer is a nutcase who spends entirely too much time alone absorbed in his own version of reality. Probably nobody ever loved him and he surely seems incapable of love. Talk about black holes? Here's a live one.
