[WT Sharpe]

Here is what George Seldes (1890 - 1995), American author and journalist, had to say about that quotation in his The Great Thoughts (1985; Introduction and a new compilation ©1996 by David Laskin):

.....Tout comprendre rend trés indulgent.
.....To understand all makes one tolerant.
..........— Madame de Staël (Anne Louise Germaine Necker, Baronne de Staël-Holstine) (1766-1817), Swiss-born French novelist. Corinne (1807).

A footnote reads:

.....Frequently misquoted as "Tout comprendre c’est tout pardonner" ["To understand all is to forgive all"]. This saying is credited, by scholars, to Buddha.


Yeah, I know. Picky, picky!
