Folly
Folly is like the growth of weeds, always luxurious and spontaneous; wisdom, like flowers, requires cultivation.
—Hosea Ballou
Folly is like a sore on a surfeited horse, cure it in one place and it breaks out in another.
—John Dryden
Dead flies cause the ointment of the apothecary to send forth a stinking savour: so doth a little folly him that is in reputation for wisdom and honour.
—Old Testament
