Fundamental premise or assumption (F):
Being a self (alternatively, being capable of feeling pain) is a moral-sphere-making characteristic; that is, anything that is a self (or, is capable of feeling pain) has moral rights.
Question: Does everything with moral rights also have moral
responsibilities?
Jaina answer: No. Animals are not responsible for their actions but still should not be injured.
Seconday argument (S):
Animals are selves (or, are capable of feeling pain), as is indicated by their behavior.
Within the moral sphere: what acts are morally right and what acts are morally wrong?
The Jaina reasoning does not provide a comprehensive answer. But we find the following, with premise A taken to follow from the fundamental assumption F:
Premise A (= conclusion C1 from F):
To propagate what selves see as bad for themselves (i.e., dislike) is to commit a moral evil.
Premise B:
Selves see pain and injury as bad for themselves.
Therefore,
Conclusion C2:
To propagate pain or injury is to commit a moral evil.
Conclusion C3 (from S and C2):
To hurt an animal is morally wrong.
