these things, I hold, require much study and are the task of a vigorous and imaginative mind:Unmistakably this phrase is parodied in Plat. Gorg. 463a: dokei= toi/nun moi, w)= *gorgia, ei)=nai ti e)pith/deuma texniko\n me\n ou)/, yuxh=s de\ stoxastikh=s kai\ a)ndrei/as kai\ fu/sei deinh=s prosomilei=n toi=s a)nqrw/pois for this, the student must not only have the requisite aptitude but he must learn the different kinds of discourse and practice himself in their use; and the teacher, for his part, must so expound the principles of the art with the utmost possible exactness as to leave out nothing that can be taught, and, for the rest, he must in himself set such an example of oratory
