Description: Article from The Actuary, April 1985, Volume 20, No. 4 that discusses from usury to interest. Usury definitions are 1 The lending out of money with an interest charge for its use: the taking or practice of taking interest 2 An unconscionable or exorbitant rate or amount of interest, specifically interest in excess of a legal rate charged to a borrower for the use of money. Between definitions 1 and 2 are 2000 years of Western history, beginning with Biblical strictures against charging any interest and reaching today's sophisticated credit economy, in which interest, per se, is accepted and only excessive interest is illegal.
