Cicero on eloquence without wisdom

Cicero Denounces Catiline, Cesare Maccari

In De Inventione (literally, On Invention), a handbook on oratory that Cicero wrote while still a young lawyer, he recorded this thought on good speech without wisdom and wisdom without good speech:

 
Wisdom without eloquence does too little for the good of communities, but eloquence without wisdom is, in most instances, extremely harmful and never beneficial.
— Cicero
 

It's worth considering both aspects of any proposals or arguments we make politically, and one has to wonder what Cicero would make of a world in which neither wisdom nor eloquence play a role in our public discourse.
