Rh tranquillity and steadiness; and a mind which was destitute of these qualities they called insane, because soundness was inconsistent with a perturbed mind just as much as with a disordered body.

V. Nor were they less ingenious in calling the state of the soul devoid of the light of the mind, "a being out of one's mind," "a being beside one's self." From whence we may understand that they who gave these names to things were of the same opinion with Socrates, that all silly people were unsound, which the Stoics have carefully preserved as being derived from him; for whatever mind is distempered (and, as I just now said, the philosophers call all perturbed motions of the mind distempers) is no more sound than a body is when in a fit of sickness. Hence it is that wisdom is the soundness of the mind, folly a sort of unsoundness, which is insanity, or a being out of one's mind: and these are much better expressed by the Latin words than the Greek, which you will find the case also in many other topics. But we will discuss that point elsewhere: let us now attend to our present subject. The very meaning of the word describes the whole thing about which we are inquiring, both as to its substance and character. For we must necessarily understand by "sound" those whose minds are under no perturbation from any motion as if it were a disease. They who are differently affected we must necessarily call "unsound." So that nothing is better than what is usual in Latin, to say that they who are run away with by their lust or anger have quitted the command over themselves; though anger includes lust, for anger is defined to be the lust of revenge. They, then, who are said not to be masters of themselves, are said to be so because they are not under the government of reason, to which is assigned by nature the power over the whole soul. Why the Greeks should call this μανία, I do not easily apprehend; but we define it much better than they, for we distinguish this madness (insania), which, being allied to folly, is more extensive, from what we call furor, or raving. The Greeks, indeed, would do so too, but they have no one word that will express it: what we call furor, they call μελαγχολία, as if the reason
