SOCRATES: And we shall take up our parable and say: Do you wish to have the greatest and most vehement pleasures for your companions in addition to the true ones? 'Why, Socrates,' they will say, 'how can we? seeing that they are the source of ten thousand hindrances to us; they trouble the souls of men, which are our habitation, with their madness; they prevent us from coming to the birth, and are commonly the ruin of the children which are born to us, causing them to be forgotten and unheeded; but the true and pure pleasures, of which you spoke, know to be of our family, and also those pleasures which accompany health and temperance, and which every Virtue, like a goddess, has in her train to follow her about wherever she goes,--mingle these and not the others; there would be great want of sense in any one who desires to see a fair and perfect mixture, and to find in it what is the highest good in man and in the universe, and to divine what is the true form of good--there would be great want of sense in his allowing the pleasures, which are always in the company of folly and vice, to mingle with mind in the cup.'--Is not this a very rational and suitable reply, which mind has made, both on her own behalf, as well as on the behalf of memory and true opinion? PROTARCHUS: Most certainly. SOCRATES: And still there must be something more added, which is a necessary ingredient in every mixture. PROTARCHUS: What is that? SOCRATES: Unless truth enter into the composition, nothing can truly be created or subsist. PROTARCHUS: Impossible. SOCRATES: Quite impossible; and now you and Philebus must tell me whether anything is still wanting in the mixture, for to my way of thinking the argument is now completed, and may be compared to an incorporeal law, which is going to hold fair rule over a living body. PROTARCHUS: I agree with you, Socrates. SOCRATES: And may we not say with reason that we are now at the vestibule of the habitation of the good? PROTARCHUS: I think that we are. SOCRATES: What, then, is there in the mixture which is most precious, and which is the principal cause why such a state is universally beloved by all? When we have discovered it, we will proceed to ask whether this omnipresent nature is more akin to pleasure or to mind. PROTARCHUS: Quite right; in that way we shall be better able to judge. SOCRATES: And there is no difficulty in seeing the cause which renders any mixture either of the highest value or of none at all. PROTARCHUS: What do you mean? SOCRATES: Every man knows it. PROTARCHUS: What? SOCRATES: He knows that any want of measure and symmetry in any mixture whatever must always of necessity be fatal, both to the elements and to the mixture, which is then not a mixture, but only a confused medley which brings confusion on the possessor of it. PROTARCHUS: Most true.
