order to minister to this (faculty) and serve it, but this faculty alone sees sharp and sees what is the value of each of the rest; will this faculty declare to us that anything else is the best, or that itself is? And what else does the eye do when it is opened than see? But whether we ought to look on the wife of a certain person, and in what manner, who tells us? The faculty of the will. And whether we ought to believe what is said or not to believe it, and if we do believe, whether we ought to be moved by it or not, who tells us? Is it not the faculty of the will? But if you ask me what then is the most excellent of all things, what must I say? I cannot say the power of speaking, but the power of the will, when it is right ([Greek: orthae]). For it is this which uses the other (the power of speaking), and all the other faculties both small and great. For when this faculty of the will is set right, a man who is not good becomes good: but when it fails, a man becomes bad. It is through this that we are unfortunate, that we are fortunate, that we blame one another, are pleased with one another. In a word, it is this which if we neglect it makes unhappiness, and if we carefully look after it, makes happiness. What then is usually done? Men generally act as a traveller would do on his way to his own country, when he enters a good inn, and being pleased with it should remain there. Man, you have forgotten your purpose: you were not travelling to this inn, but you were passing through it. But this is a pleasant inn. And how many other inns are pleasant? and how many meadows are pleasant? yet only for passing through. But your purpose is this, to return to your country, to relieve your kinsmen of anxiety, to discharge the duties of a citizen, to marry, to beget children, to fill the usual magistracies. For you are not come to select more pleasant places, but to live in these where you were born and of which you were made a citizen. Something of the kind takes place in the matter which we are considering. Since by the aid of speech and such communication as you receive here you must advance to perfection, and purge your will and correct the faculty which makes use of the appearances of things; and since it is necessary also for the teaching (delivery) of theorems to be effected by a certain mode of expression and with a certain variety and sharpness, some persons captivated by these very things abide in them, one captivated by the expression, another by syllogisms, another again by sophisms, and still another by some other inn ([Greek: paudocheiou]) of the kind; and there they stay and waste away as they were among sirens.
