But what is the good? Some say pleasure, others knowledge, which they absurdly explain to mean knowledge of the good. You are further aware that most people affirm pleasure to be the good, but the finer sort of wits say it is knowledge?
Yes.
And you are aware too that the latter cannot explain what they mean by knowledge, but are obliged after all to say knowledge of the good?
How ridiculous!
[C] Yes, I said, that they should begin by reproaching us with our ignorance of the good, and then presume our knowledge of it—for the good they define to be knowledge of the good, just as if we understood them when they use the term ‘good’—this is of course ridiculous.
Most true, he said.
And those who make pleasure their good are in equal perplexity; for they are compelled to admit that there are bad pleasures as well as good.
Certainly.
And therefore to acknowledge that bad and good are the same?
[D] True.
