"The most difficult thing in life is to know yourself."

"To be good and to be bad, these are not things, but only words."

"There are no conditions to which a man cannot get accustomed, especially if he sees that all around him are living in the same way."

"Faith is the sense of life, that sense by virtue of which man does not destroy himself, but continues to live on. It is the force whereby we live."

"A man is like a fraction whose numerator is what he is and whose denominator is what he thinks of himself. The larger the denominator, the smaller the fraction."
