"Definition of insanity" quote has been misattributed to Einstein
(whatever)I'm sure everyone has heard it before: "Insanity is doing the same thing over and over again but expecting different results." Of course Einstein never said that expression. For some time, it was misattributed to the feminist lesbian writer Rita Mae Brown, but it seems she just borrowed it. The actual origin of the expression, that is, the earliest use of it, is a 1981 version of the book "Narcotics Anonymous". The more you know.
