v.t. To rebuke bluntly, but not pointedly; to dispel a source of error in an opponent.

(also: The Devil's Dictionary)

n. An apparatus with which we think that we think. That which distinguishes the man who is content to be something from the man who wishes to do something. A man of great wealth, or one who has been pitchforked into high station, has commonly such a headful of brain that his neighbors cannot keep their hats on. In our civilization, and under our republican form of government, brain is so highly honored that it is rewarded by exemption from the cares of office.

(also: The Devil's Dictionary)

(n.) the organ contained within the head of a life form; all that separates a thinking, living being and a pile of rotting meat
