[7] : Jargon File (4.3.1, 29 Jun 2001)

fool n. as used by hackers, specifically describes a person who
   habitually reasons from obviously or demonstrably incorrect premises and
   cannot be persuaded by evidence to do otherwise; it is not generally
   used in its other senses, i.e., to describe a person with a native
   incapacity to reason correctly, or a clown. indeed, in hackish
   experience many fools are capable of reasoning all too effectively in
   executing their errors. see also cretin, loser, fool file.

   the algol 68-r compiler used to initialize its storage to the
   character string "f00lf00lf00lf00l..." because as a pointer or as a
   floating point number it caused a crash, and as an integer or a
   character string it was very recognizable in a dump. sadly, one day a
   very senior professor at nottingham university wrote a program that
   called him a fool. he proceeded to demonstrate the correctness of this
   assertion by lobbying the university not quite successfully to forbid
   the use of algol on its computers. see also deadbeef.

[9] : THE DEVIL'S DICTIONARY ((C)1911 Released April 15 1993)

fool, n.  a person who pervades the domain of intellectual speculation
and diffuses himself through the channels of moral activity.  he is
omnific, omniform, omnipercipient, omniscience, omnipotent.  he it was
who invented letters, printing, the railroad, the steamboat, the
telegraph, the platitude and the circle of the sciences.  he created
patriotism and taught the nations war -- founded theology, philosophy,
law, medicine and chicago.  he established monarchical and republican
government.  he is from everlasting to everlasting -- such as
creation's dawn beheld he fooleth now.  in the morning of time he sang
upon primitive hills, and in the noonday of existence headed the
procession of being.  his grandmotherly hand was warmly tucked-in the
set sun of civilization, and in the twilight he prepares man's evening
meal of milk-and-morality and turns down the covers of the universal
grave.  and after the rest of us shall have retired for the night of
eternal oblivion he will sit up to write a history of human
civilization.
