The Talmud in Wikipedia
The highest form of wisdom is kindness
When you teach your son, you teach your son's son.
Who is wise? One who learns from all.
Sin is sweet in the beginning, but bitter in the end.
The end result of wisdom is... good deeds.
Thought is subversive and revolutionary, destructive and terrible, Thought is merciless to privilege, established institutions, and comfortable habit. Thought is great and swift and free.
(May 18, 1872 - February 02, 1970)

Quarrels end, but words once spoken never die
