The intoxication of anger, like that of the grape, shows us to others, but hides us from ourselves; and we injure our own cause, in the opinion of the world, when we too passionately and eagerly defend it; […] Neither will all men be disposed to view our quarrels precisely in the same light that we do; and a man’s blindness to his own defects will ever increase, in proportion as he is angry with others, or pleased with himself.

Charles Caleb "C. C." Colton (1780-1832) English cleric, writer, aphorist

Lacon: or, Many Things in Few Words, #240 (1824 ed.)
