P is for "The Devil's Dictionary" (No. 206 in a series)

The Devil's Dictionary is a satirical dictionary written by Ambrose Bierce (1842-c.1914, caricatured above by David Levine). Bierce was an American author who began the book as a newspaper serial. First published in 1906 as The Cynic's Word Book, it was retitled in 1911, using the name we know it by today, which is the title that Bierce preferred. Some of the definitions have not aged all that well, but many have.

PRECEDENT, n. In Law, a previous decision, rule or practice which, in the absence of a definite statute, has whatever force and authority a Judge may choose to give it, thereby greatly simplifying his task of doing as he pleases. As there are precedents for everything, he has only to ignore those that make against his interest and accentuate those in the line of his desire. Invention of the precedent elevates the trial-at-law from the low estate of a fortuitous ordeal to the noble attitude of a dirigible arbitrament.
