“I don't need a friend who changes when I change and who nods when I nod; my shadow does that much better”

“Never explain - your friends do not need it and your enemies will not believe you anyway ”

“Children have more need of models than of critics”

“In order to love simply, it is necessary to know how to show love”

“It is error alone which needs the support of government. Truth can stand by itself”
