“Videndum est, non modo quid quisque loquatur, sed etiam quid
     quisque sentiat, atque etiam qua de causa quisque sentiat.”

     ["A man is not only to examine what every one says, but also what
     every one thinks, and from what reason every one thinks.” 
     —­Cicero, De Offic:, i. 41.]

I every day hear fools say things that are not foolish:  they say a good thing; let us examine how far they understand it, whence they have it, and what they mean by it.  We help them to make use of this fine expression, of this fine sentence, which is none of theirs; they only have it in keeping; they have bolted it out at a venture; we place it for them in credit and esteem.  You lend them your hand.  To what purpose? they do not think themselves obliged to you for it, and become more inept still.  Don’t help them; let them alone; they will handle the matter like people who are afraid of burning their fingers; they dare change neither its seat nor light, nor break into it; shake it never so little, it slips through their fingers; they give it up, be it never so strong or fair they are fine weapons, but ill hafted:  How many times have I seen the experience of this?  Now, if you come to explain anything to them, and to confirm them, they catch at it, and presently rob you of the advantage of your interpretation; “It was what I was about to say; it was just my idea; if I did not express it so, it was for want of language.”  Mere wind!  Malice itself must be employed to correct this arrogant ignorance.  The dogma of Hegesias, “that we are neither to hate nor accuse, but instruct,” is correct elsewhere; but here ’tis injustice and inhumanity to relieve and set him right who stands in no need on’t, and is the worse for’t.  I love to let them step deeper into the mire; and so deep, that, if it be possible, they may at last discern their error.

Folly and absurdity are not to be cured by bare admonition; and what Cyrus answered to him, who importuned him to harangue his army, upon the point of battle, “that men do not become valiant and warlike upon a sudden, by a fine oration, no more than a man becomes a good musician by hearing a fine song,” may properly be said of such an admonition as this.  These are apprenticeships that are to be served beforehand, by a long and continued education.  We owe this care and this assiduity of correction and instruction to our own people; but to go preach to the first passer-by, and to become tutor to the ignorance and folly of the first we meet, is a thing that I abhor.  I rarely do it, even in private conversation, and rather give up the whole thing than proceed to these initiatory and school instructions; my humour is unfit either to speak or write for beginners; but for things that are said in common discourse, or amongst other things, I never oppose them either by word or sign, how false or absurd soever.
