For Dave and Ian (The odd couple)

Plato on anger.

Plato also reveals a complex interconnection between the spirited part, the emotional response of anger, and conceptions (right or wrong) of justice and injustice. Anger arises from a perception not only that some harm has been done, some inconvenience has been imposed, some wish, desire, or intention has been frustrated -- but all the more from a sense that some wrong has been committed, that someone or something is unjust. This depends then very much upon what a person thinks or feels to be unjust -- and likewise by contrast what they feel to be just. If a person is mistaken about these matters, or even has a rather confused, emotionally-driven conception of justice and injustice, they are much more likely to become angry in the first place -- and will also get angry over things they ought not to get angry about. In general:

. . . "when he thinks that he is the sufferer of the wrong, then he boils and chafes, and is on the side of what he believes to be justice; and because he suffers hunger or cold or other pain he is only the more determined to persevere and conquer. His noble spirit will not be quelled until he either slays or is slain; or until he hears the voice of the shepherd, that is, reason, bidding his dog bark no more."
