Cicero, in de Inventione, says that wisdom without eloquence does too little for the good of states is of little use to states but eloquence without wisdom is generally highly disadvantageous and is never helpful (I.i). What does he mean by this? What do the ancients mean by wisdom and eloquence? What role does instruction in the art (techne) of rhetoric contribute to the development of an ideal orator? What does the orator need to know? How does one become a perfect orator?
