A man may desire something that does not affect him personally except because of his desire—for instance, the victory of one side in a war in which his country is neutral.

Context

“Anything whatever may be an object of desire; a masochist may desire his own pain. The masochist, no doubt, derives pleasure from the pain that he has desired, but the pleasure is because of the desire, not vice versa. A man may desire something that does not affect him personally except because of his desire—for instance, the victory of one side in a war in which his country is neutral. He may desire an increase of general happiness, or a mitigation of general suffering. Or he may, like Carlyle, desire the exact opposite. As his desires vary, so do his pleasures. Ethics is necessary because men’s desires conflict.” source
