SOCRATES: Or, again, when cold and heat prevail, does not the introduction of them take away excess and indefiniteness, and infuse moderation and harmony?
PROTARCHUS: Certainly.
SOCRATES: And from a like admixture of the finite and infinite come the seasons, and all the delights of life?
PROTARCHUS: Most true.
SOCRATES: I omit ten thousand other things, such as beauty and health and strength, and the many beauties and high perfections of the soul: O my beautiful Philebus, the goddess, methinks, seeing the universal wantonness and wickedness of all things, and that there was in them no limit to pleasures and self-indulgence, devised the limit of law and order, whereby, as you say, Philebus, she torments, or as I maintain, delivers the soul.—What think you, Protarchus?
PROTARCHUS: Her ways are much to my mind, Socrates.
SOCRATES: You will observe that I have spoken of three classes?
PROTARCHUS: Yes, I think that I understand you: you mean to say that the infinite is one class, and that the finite is a second class of existences; but what you would make the third I am not so certain.
SOCRATES: That is because the amazing variety of the third class is too much for you, my dear friend; but there was not this difficulty with the infinite, which also comprehended many classes, for all of them were sealed with the note of more and less, and therefore appeared one.
PROTARCHUS: True.
