158 OF THE ADVANCEMENT OP LEARNING 



in this, that logic handleth reason exact and in truth, 

 and rhetoric handleth it as it is planted in popular 

 opinions and manners. And therefore Aristotle doth 

 wisely place rhetoric as between logic on the one side, 

 and moral or civil knowledge on the other, as partici- 

 pating of both : for the proofs and demonstrators of 

 logic are toward all ijien indifferent and the same ; but 

 the proofs and persuasions of rhetoric ought to differ 

 according to the auditors : 



Orpheus in sylvis, inter delphinas Arion. 



Which application, in perfection of idea, ought to extend 



so far, that if a man should speak of the same thing to 



several persons, he should speak to them all respectively 



and several ways : though this politic part of eloquence 



in private speech it is easy for the greatest orators to 



want : whilst, by the observing their 



Deprudentia well-graced forms of speech, they lease the 



privati' volubility of application : and therefore 



it shall not be amiss to recommend this to 



better inquiry, not being curious whether we place it 



here, or in that part which concerneth policy. 



6. Now therefore will I descend to the deficiencies, 



Colores boni which (as I said) are but attendances : 



etmaii, and first, I do not find the wisdom and 



aimpiiciset diligence of Aristotle well pursued, who 



comparati. began to make a collection of the popular 



signs and colours of good and evil, both simple and 



comparative, which are as the sophisms of rhetoric (as 



I touched before). For example : 



SopMsma. 

 Quod laudatur, bonum: quod vituperatur, malum. 



Redargutio. 

 Laudat venales qui vult extrudere merces. 



* Malum est, malum est (inquit emptor) ; sed cum 

 recesserit, tum gloriabitur ! ' The defects in the labour 

 of Aristotle are three : one, that there be but a few of 

 many ; another, that their clenches are not annexed ; 

 and the third, that he conceived but a part of the use
