And what would you say of the physician? In prescribing meats and drinks would he wish to go beyond another physician or beyond the practice of medicine?

He would not.

But he would wish to go beyond the non-physician?

Yes.

And about knowledge and ignorance in general; see whether you think that any man who has knowledge ever would wish to have the choice of saying or doing more than another man who has knowledge. Would he not rather say or do the same as his like in the same case?

That, I suppose, can hardly be denied.

And what of the ignorant?

would he not desire to have more than either the knowing or the ignorant?
