Kinds of Pleasure: "For I think Socrates is asking us whether there are or are not kinds of pleasure, how many kinds there are, what their nature is, and the same of wisdom." https://archive.org/details/b2900049x_0008/page/229/mode/1up
Is the Nature of the good perfect or imperfect, sufficient or insufficient? soc. Is the nature of the good necessarily perfect or imperfect ? pro. The most perfect of all things, surely, Socrates. soc. Well, and is the good sufficient ?
pro. Of course ; so that it surpasses all other things in sufficiency. https://archive.org/details/b2900049x_0008/page/233/mode/1up
The good cannot have need of anything else. soc. Let there be no wisdom in the life of pleasure and no pleasure in the life of wisdom. For if either of them is the good, it cannot have need of anything else, and if either be found to need anything, we can no longer regard it as our true good. https://archive.org/details/b2900049x_0008/page/235/mode/1up
The Limits Argument:
Consider the hotter and the colder, is there any limit in them? soc. Consider then. What I ask you to consider is difficult and debatable ; but consider it all the same. In the first place, take hotter and colder and see whether you can conceive any limit of them, or whether the more and less which dwell in their very nature do not, so long as they continue to dwell therein, preclude the possibility of any end ; for if there were any end of them, the more and less would themselves be ended. https://archive.org/details/b2900049x_0008/page/245/mode/1up
Socrates suggests that a goddess higher than pleasure established law and order, which has a limit, to restrain pleasure, which does not have a limit:. soc. There are countless other things which I pass over, such as health, beauty, and strength of the body and the many glorious beauties of the soul. For this goddess , 1 my fair Philebus, beholding the violence and universal wickedness which prevailed, since there was no limit of pleasures or of indulgence in them, established law and order, which contain a limit. You say she did harm ; I say, on the contrary, she brought salvation. https://archive.org/details/b2900049x_0008/page/253/mode/1up
Have pleasure and pain a limit? (27e) Soc. Have pleasure and pain a limit, or are they among the things which admit of more and less phi. Yes, they are among those which admit of the more, Socrates ; for pleasure would not be absolute good if it were not infinite in number and degree. soc. Nor would pain, Philebus, be absolute evil ; so it is not the infinite which supplies any element of good in pleasure ; we must look for something else. Well, I grant you that pleasure and pain are in the class of the infinite ; but to which of the aforesaid classes, Protarchus and Philebus, can we now without irreverence assign wisdom, knowledge, and mind ? I think we must find the right answer to this question, for our danger is great if we fail. https://archive.org/details/b2900049x_0008/page/259/mode/1up Perseus Link
