I feel loyal to someone because of a bond of family, friendship, collaboration, or purpose. I’m moved by an idealistic sense of duty. But in supporting him I’m committing myself to the welfare of an individual person — and that’s practically the opposite of idealism.
“The first assumption casts the loyal agent as praiseworthy from an impartial point of view,” writes Irish philosopher Philip Pettit. “The second presents him as the very exemplar of partial concern. … To be loyal is to be dedicated to a particular individual’s welfare, and that seems to conflict with the idea that the loyal agent is idealistic or dutiful.”
