If you want to see that angry people aren't thinking straight, just look at them. We can spot madmen by their appearance — they look bold and threatening, with dark expressions, stern faces, hurried movements, restless hands, strange coloring, and fast, heavy breathing. Angry people look exactly the same. Their eyes blaze and sparkle. Their whole face turns deep red as blood rushes up from their heart. Their lips shake, they clench their teeth, their hair stands up. They breathe hard and make hissing sounds. Their joints crack as they twist around. They groan and bellow and speak in ways you can barely understand. They clap their hands and stomp their feet. Their whole body is wound tight and does all the crazy things that show a disturbed mind. It's an ugly, shocking picture of someone who has lost control of themselves.
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.
