"swearing is, as I have said, learning to the ignorant, eloquence to the blockhead, vivacity to the stupid, and wit to the coxcomb."

A well-read fool is the most pestilent of blockheads; his learning is a flail which he knows not how to handle, and with which he breaks his neighbor's shins as well as his own. Keep a fellow of this description at arm's length, as you value the integrity of your bones.
