⁴ If, however, you hesitate to accept this example as a parallel one, when it is thus cursorily stated by me, turn it over in your thoughts as fully as you can. The mind, if it be continually obstructed by some difficulty in the way of doing and accomplishing what it desires, is thereby made continually angry. For anger, so far as I can judge of its nature, seems to me to be a tumultuous eagerness to take out of the way those things which restrict our freedom of action. Hence it is that usually we vent our anger not only on men, but on such a thing, for example, as the pen with which we write, bruising or breaking it in our passion; and so does the gambler with his dice, the artist with his pencil, and every man with the instrument which he may be using, if he thinks that he is in some way thwarted by it. Now medical men themselves tell us that by these frequent fits of anger bile is increased. But, on the other hand, when the bile is increased, we are easily, and almost without any provocation whatever, made angry. Thus the effect which the mind has by its movement produced upon the body, is capable in its turn of moving the mind again.
