David Hume,
Treatise of Human Nature/Book 2…
(1739)
“ This is a clear proof, that, independent of the opinion of iniquity, any harm or uneasiness has a natural tendency to excite our hatred, and that afterwards we seek for reasons upon which we may justify and establish the passion. Here the idea of injury produces not the passion, but arises from it. Nor is it any wonder that passion should produce the opinion of injury; since otherwise it must suffer a considerable diminution, which all the passions avoid as much as possible. The removal of injury may remove the anger, without proving that the anger arises only from the injury. ”
