Ly. You take a thing whose nature is self-evident and universally admitted, like wine, and argue from it to perfectly unlike things, whose nature is obscure and generally debated. In fact I cannot tell what analogy you find between philosophy and wine; there is just one, indeed: philosophers and wine-merchants both sell their wares, mostly resorting to adulteration, fraud, and false measures, in the process. But let us look into your real meaning. You say all the wine in a cask is of the same quality—which is perfectly reasonable; further, that any one who draws and tastes quite a small quantity will know at once the quality of the whole—of which the same may be said; I should never have thought of objecting. But mark what comes now: do philosophy and its professors (your own, for instance) give you every day the same remarks on the same subjects, or do they vary them? They vary them a great deal, friend; you would never have stuck to your master through your twenty years' wandering—quite a philosophic Odyssey—if he had always said the same thing; one hearing would have been enough.
Her. So it would.
Ly. How could you have known the whole of his doctrines from the first taste, then? They were not homogeneous, like the wine; novelty to-day, and novelty to-morrow on the top of it. Consequently, dear friend, short of drinking the whole cask, you might soak to no purpose; Providence seems to me to have hidden the philosophic Good right at the bottom, underneath the lees. So you will have to drain it dry, or you will never get to that nectar for which I know you have so long thirsted. According to your idea, it has such virtue that, could you once taste it and swallow the very least drop, you would straightway have perfect wisdom; so they say the Delphian prophetess is inspired by one draught of the sacred spring with answers for those who consult the oracle. But it seems not to be so; you have drunk more than half the cask; yet you told me you were only beginning yet.
Now see whether this is not a better analogy. You shall keep your merchant, and your cask; but the contents of the latter are not to be wine, but assorted seeds. On the top is wheat, next beans, then barley, below that lentils, then peas—and other kinds yet. You go to buy seeds, and he takes some wheat out of that layer, and puts it in your hand as a sample; now, could you tell by looking at that whether the peas were Sound, the lentils tender, and the beans full?
Her. Impossible.
Ly. No more can you tell the quality of a philosophy from the first statements of its professor; it is not uniform, like the wine to which you compared it, claiming that it must resemble the sample glass; it is heterogeneous, and it had better not be cursorily tested. If you buy bad wine, the loss is limited to a few pence; but to rot with the common herd (in your own words) is not so light a loss. Moreover, your man who wants to drink up the cask as a preliminary to buying a pint will injure the merchant, with his dubious sampling; but philosophy knows no such danger; you may drink your fill, but this cask grows no emptier, and its owner suffers no loss. It is cut and come again here; we have the converse of the Danaids' cask; that would not hold what was put into it; it ran straight through; but here, the more you take away, the more remains.
And I have another similar remark to make about these specimen drops of philosophy. Do not fancy I am libelling it, if I say it is like hemlock, aconite, or other deadly poison. Those too, though they have death in them, will not kill if a man scrapes off the tiniest particle with the edge of his nail and tastes it; if they are not taken in the right quantity, the right manner, and the right vehicle, the taker will not die; you were wrong in claiming that the least possible quantity is enough to base a generalization on.
Her. Oh, have it your own way, Lycinus. Well then, we have got to live a hundred years, and go through all this trouble? There is no other road to philosophy?
Ly. No, none; and we need not complain; as you very truly said, ars longa, vita brevis. But I do not know what has come over you; you now make a grievance of it, if you cannot before set of sun develop into a Chrysippus, a Plato, a Pythagoras.
Her. You trap me, and drive me into a corner, Lycinus; yet I never provoked you; it is all envy, I know, because I have made some progress in my studies, whereas you have neglected yourself, when you were old enough to know better.
