“ Immodest words admit of no defense, for want of modesty is want of sense. ”
 Benjamin Franklin, The Autobiography of Benjamin Franklin (1791). copy citation

Context

“And things unknown propos'd as things forgot;" farther recommending to us "To speak, tho' sure, with seeming diffidence."
And he might have coupled with this line that which he has coupled with another, I think, less properly, "For want of modesty is want of sense."
If you ask, Why less properly? I must repeat the lines,
"Immodest words admit of no defense, For want of modesty is want of sense."
Now, is not want of sense (where a man is so unfortunate as to want it) some apology for his want of modesty?” source
