That you may know that they whom anger possesses are not sane, look at their appearance; for as there are distinct symptoms which mark madmen, such as a bold and menacing air, a gloomy brow, a stern face, a hurried walk, restless hands, changed colour, quick and strongly-drawn breathing; the signs of angry men, too, are the same: their eyes blaze and sparkle, their whole face is a deep red with the blood which boils up from the bottom of their heart, their lips quiver, their teeth are set, their hair bristles and stands on end, their breath is laboured and hissing, their joints crack as they twist them about, they groan, bellow, and burst into scarcely intelligible talk, they often clap their hands together and stamp on the ground with their feet, and their whole body is highly-strung and plays those tricks which mark a distraught mind, so as to furnish an ugly and shocking picture of self-perversion and excitement. You cannot tell whether this vice is more execrable or more disgusting. Other vices can be concealed and cherished in secret; anger shows itself openly and appears in the countenance, and the greater it is, the more plainly it boils forth.
