On Tom Nagel’s review of Christine Kosgaard’s book, Fellow Creatures: Our Obligations to the Other Animals.
Philosophers’ make commendable (but unavailing) efforts to rationalize (and even formalize) morality.
It’s all much simpler than all this, but I haven’t the time to sketch it long-hand.
The only biological necessity (vital interest) is survival and freedom from suffering.
it is sentient living organisms who have vital interests.
There can be conflicts between the vital interests of different sentients (e.g, predator and prey).
The only moral imperative is to not cause unnecessary suffering.
Taste is not a vital interest.
