I have long been silently asking myself, my friend Serenus, to what I should liken such a condition of mind, and I find that nothing more closely resembles it than the conduct of those who, after having recovered from a long and serious illness, occasionally experience slight touches and twinges, and, although they have passed through the final stages of the disease, yet have suspicions that it has not left them, and though in perfect health yet hold out their pulse to be felt by the physician, and whenever they feel warm suspect that the fever is returning. Such men, Serenus, are not unhealthy, but they are not accustomed to being healthy; just as even a quiet sea or lake nevertheless displays a certain amount of ripple when its waters are subsiding after a storm. What you need, therefore, is, not any of those harsher remedies to which allusion has been made, not that you should in some cases check yourself, in others be angry with yourself, in others sternly reproach yourself, but that you should adopt that which comes last in the list, have confidence in yourself, and believe that you are proceeding on the right path, without being led aside by the numerous divergent tracks of wanderers which cross it in every direction, some of them circling about the right path itself. What you desire, to be undisturbed, is a great thing, nay, the greatest thing of all, and one which raises a man almost to the level of a god. The Greeks call this calm steadiness of mind euthymia, and Democritus's treatise upon it is excellently written: I call it peace of mind: for there is no necessity for translating so exactly as to copy the words of the Greek idiom: the essential point is to mark the matter under discussion by a name which ought to have the same meaning as its Greek name, though perhaps not the same form. What we are seeking, then, is how the mind may always pursue a steady, unruffled course, may be pleased with itself, and look with pleasure upon its surroundings, and experience no interruption of this joy, but abide in a peaceful condition without being ever either elated or depressed: this will be "peace of mind." Let us now consider in a general way how it may be attained: then you may apply as much as you choose of the universal remedy to your own case. Meanwhile we must drag to light the entire disease, and then each one will recognize his own part of it: at the same time you will understand how much less you suffer by your self-depreciation than those who are bound by some showy declaration which they have made, and are oppressed by some grand title of honour, so that shame rather than their own free will forces them to keep up the pretence. The same thing applies both to those who suffer from fickleness and continual changes of purpose, who always are fondest of what they have given up, and those who merely yawn and dawdle: add to these those who, like bad sleepers, turn from side to side, and settle themselves first in one manner and then in another, until at last they find rest through sheer weariness: in forming the habits of their lives they often end by adopting some to which they are not kept by any dislike of change, but in the practice of which old age, which is slow to alter, has caught them living: add also those who are by no means fickle, yet who must thank their dullness, not their consistency for being so, and who go on living not in the way they wish, but in the way they have begun to live. There are other special forms of this disease without number, but it has but one effect, that of making people dissatisfied with themselves. This arises from a distemperature of mind and from desires which one is afraid to express or unable to fulfill, when men either dare not attempt as much as they wish to do, or fail in their efforts and depend entirely upon hope: such people are always fickle and changeable, which is a necessary consequence of living in a state of suspense: they take any way to arrive at their ends, and teach and force themselves to use both dishonourable and difficult means to do so, so that when their toil has been in vain they are made wretched by the disgrace of failure, and do not regret having longed for what was wrong, but having longed for it in vain. They then begin to feel sorry for what they have done, and afraid to begin again, and their mind falls by degrees into a state of endless vacillation, because they can neither command nor obey their passions, of hesitation, because their life cannot properly develop itself, and of decay, as the mind becomes stupefied by disappointments. All these symptoms become aggravated when their dislike of a laborious misery has driven them to idleness and to secret studies, which are unendurable to a mind eager to take part in public affairs, desirous of action and naturally restless, because, of course, it finds too few resources within itself: when therefore it loses the amusement which business itself affords to busy men, it cannot endure home, loneliness, or the walls of a room, and regards itself with dislike when left to itself. Hence arises that weariness and dissatisfaction with oneself, that tossing to and fro of a mind which can nowhere find rest, that unhappy and unwilling endurance of enforced leisure. In all cases where one feels ashamed to confess the real cause of one's suffering, and where modesty leads one to drive one's sufferings inward, the desires pent up in a little space without any vent choke one another. Hence comes melancholy and drooping of spirit, and a thousand waverings of the unsteadfast mind, which is held in suspense by unfulfilled hopes, and saddened by disappointed ones: hence comes the state of mind of those who loathe their idleness, complain that they have nothing to do, and view the progress of others with the bitterest jealousy: for an unhappy sloth favours the growth of envy, and men who cannot succeed themselves wish everyone else to be ruined. This dislike of other men's progress and despair of one's own produces a mind angered against fortune, addicted to complaining of the age in which it lives to retiring into corners and brooding over its misery, until it becomes sick and weary of itself: for the human mind is naturally nimble and apt at movement: it delights in every opportunity of excitement and forgetfulness of itself, and the worse a man's disposition the more he delights in this, because he likes to wear himself out with busy action, just as some sores long for the hands that injure them and delight in being touched, and the foul itch enjoys anything that scratches it. Similarly I assure you that these minds over which desires have spread like evil ulcers, take pleasure in toils and troubles, for there are some things which please our body while at the same time they give it a certain amount of pain, such as turning oneself over and changing one's side before it is wearied, or cooling oneself in one position after another. It is like Homer's Achilles lying first upon its face, then upon its back, placing itself in various attitudes, and, as sick people are wont, enduring none of them for long, and using changes as though they were remedies. Hence men undertake aimless wanderings, travel along distant shores, and at one time at sea, at another by land, try to soothe that fickleness of disposition which always is dissatisfied with the present. "Now let us make for Campania: now I am sick of rich cultivation: let us see wild regions, let us thread the passes of Bruttii and Lucania: yet amid this wilderness one wants some thing of beauty to relieve our pampered eyes after so long dwelling on savage wastes: let us seek Tarentum with its famous harbour, its mild winter climate, and its district, rich enough to support even the great hordes of ancient times. Let us now return to town: our ears have too long missed its shouts and noise: it would be pleasant also to enjoy the sight of human bloodshed." Thus one journey succeeds another, and one sight is changed for another. As Lucretius says:—

"Thus every mortal from himself doth flee;"

but what does he gain by so doing if he does not escape from himself? he follows himself and weighs himself down by his own most burdensome companionship. We must understand, therefore, that what we suffer from is not the fault of the places but of ourselves: we are weak when there is anything to be endured, and cannot support either labour or pleasure, either one's own business or anyone else's for long. This has driven some men to death, because by frequently altering their purpose they were always brought back to the same point, and had left themselves no room for anything new. They had become sick of life and of the world itself, and as all indulgences palled upon them they began to ask themselves the question, "How long are we to go on doing the same thing?"
