PHILINTE: A gentleman may be respected still,
Whether he writes a sonnet well or ill.
That I dislike his verse should not offend him;
In all that touches honor, I commend him;
He’s noble, brave, and virtuous — but I fear
He can’t in truth be called a sonneteer.”

On peut être honnête homme, et faire mal des vers,
Ce n’est point à l’honneur que touchent ces matières,
Je le tiens galant homme en toutes les manières,
Homme de qualité, de mérite et de cœur,
Tout ce qu’il vous plaira, mais fort méchant auteur.

Molière (1622-1673) French playwright, actor [stage name for Jean-Baptiste Poquelin]
Le Misanthrope, Act 4, sc. 1, ll. 1144-48 (1666) [tr. Wilbur (1954)]

• "A man can be a gentleman and make bad verses. Such matters do not touch his honor, and I hold him to be a gallant man in every other way; a man of quality, of courage, deserving of anything you please, but -- a bad writer." [tr. Wormeley (1894)]
• "A man may be / A perfect gentleman, and write poor verse. / These matters do not raise the point of honor. / I hold him a true man in all respects, / Brave, worthy, noble, anything you will, / But still, a wretched writer." [tr. Page (1913)]
• "Anyone may be an honorable man, and yet write verse badly." [Bartlett]
