Forber, Patrick and Jones, Robert C (2020) Spineless and sentient: a challenge for moral comparison. Animal Sentience 29(30)
Irina Mikhalevich and Russell Powell, Minds without spines: Evolutionarily inclusive animal ethics
We agree with Mikhalevich & Powell but take issue with their criteria for attributing sentience. This problem is connected with difficult issues concerning moral comparisons and evaluating moral decisions when interspecific moral interests conflict.
