peace of mind - quotes

Georg Christoph Lichtenberg, 1742-1799

was a German scientist, satirist and Anglophile

Nothing is more conducive to peace of mind than not having any opinions at all.

Anatole France (François-Anatole Thibault), 1844-1924

was a French novelist

Ignorance is a necessary condition of human happiness, and it must be owned that in most cases we fulfill it well. We know almost nothing about ourselves; absolutely nothing about our neighbors. Ignorance constitutes our peace of mind; self- deception our felicity.

( “The Gods are Thirsty”, 1912 )
