It is now evident from these considerations what
is the disposition of those who are angry, with whom they are angry, and for
what reasons. Men are angry when they are pained, because one who is pained aims
at something; if then anyone directly opposes him in anything, as, for instance,
prevents him from drinking when thirsty, or not directly, but seems to be doing
just the same; and if anyone goes against him or refuses to assist him, or
troubles him in any other way when he is in this frame of mind, he is angry with
all such persons.
