Sympathy for animals is regarded by many thinkers as theoretically disreputable. Against this I argue that sympathy appropriately underlies moral concern for animals. I offer an account of sympathy that distinguishes sympathy with from sympathy for fellow creatures, and I argue that both can be placed on an objective basis, if we differentiate enlightened from folk sympathy. Moreover, I suggest that sympathy for animals is not, as some have claimed, incompatible with environmentalism; on the contrary, it can ground environmental concern. (...) Finally, I show that the traditional concept of anthropomorphism has no coherent basis, and I argue that the attempt to prove that animals lack thoughts is both unsuccessful and irrelevant to sympathy for languageless creatures.
