For I must remark, Thrasymachus, if you will recall what was previously said, that although you began by defining the true physician in an exact sense, you did not observe a like exactness when speaking of the shepherd; you thought that the shepherd as a shepherd tends the sheep not with a view to their own good, but like a mere diner or banqueter with a view to the pleasures of the table; or, again, as a trader for sale in the market, and not as a shepherd.
