What is the meaning of men are not angered by mere misfortune but by misfortune conceive as injury?

Answer 1

It's about the problem of evil and suffering in the world, and the way people respond to it. Simply put, a person doesn't get angry about something unless he feels that the thing he is angry about was done intentionally to him or by negligence. A person who swears at a red light is somehow personifying it, as if the light had a will and a choice about how it functioned, and it chose to defy him and make him stop. He percieves that it has "injured him", and, he is irrational. But, a reasonable person would understand that the light simply turns achording to it's mechanisms; it has no choice because it is metal and plastic and glass, and therefore, would not be angy, at least, not angry at the light.
