The only true thoughts are those which do not understand themselves.
Learning consists in the modification of certain mediating processes which operate between the stimulus and the response.
"The truth is rarely pure and never simple."
你不能希望在不改善個人的情況下建立一個更好的世界。為此，我們每個人都必須為自己的改進而努力，同時也要為全人類承擔共同的責任，我們的特殊職責是幫助那些我們認為我們最有用的那些人。
Wherever you go, you take yourself with you.
