Then, according to you, we shall never finish our quest nor be philosophers, but have to give it up and live the life of laymen. What you say amounts to that: philosophy is impossible and inaccessible to a mere mortal; for you expect the aspirant first to choose the best philosophy; and you considered that the only guarantee of such choice’s being correct was to go through all philosophy before choosing the truest. Then in reckoning the number of years required by each you spurned all limits, extended the thing to several generations, and made out the quest of truth too long for the individual life; and now you crown all by proving success doubtful even apart from all that; you say it is uncertain whether the philosophers have ever found truth at all.
Could you state on oath that they have?
Not on oath, no.
And yet there is much that I have intentionally spared you, though it merits careful examination too.
For instance?
Is it not said that, among the professed Stoics, Platonists, and Epicureans, some do know their respective doctrines, and some do not (without prejudice to their general respectability)?
That is true.
Well, don’t you think it will be a troublesome business to distinguish the first, and know them from the ignorant professors?
Very.
So, if you are to recognize the best of the Stoics, you will have to go to most, if not all, of them, make trial, and appoint the best your teacher, first going through a course of training to provide you with the appropriate critical faculty; otherwise you might mistakenly prefer the wrong one. Now reflect on the additional time this will mean; I purposely left it out of account, because I was afraid you might be angry; all the same, it is the most important and necessary thing of all in questions like this—so uncertain and dubious, I mean, For the discovery of truth, your one and only sure or well-founded hope is the possession of this power: you must be able to judge and sift truth from falsehood; you must have the assayer’s sense for sound and true or forged coin; if you could have come to your examination of doctrines equipped with a technical skill like that, I should have nothing to say; but without it there is nothing to prevent their severally leading you by the nose; you will follow a dangled bunch of carrots like a donkey; or, better still, you will be water spilt on a table, trained whichever way one chooses with a finger-tip; or again, a reed growing on a river’s bank, bending to every breath, however gentle the breeze that shakes it in its passage.
