“Six mistakes mankind keeps making century after century:Believing that personal gain is made by crushing others;Worrying about things that cannot be changed or corrected;Insisting that a thing is impossible because we cannot accomplish it;Refusing to set aside trivial preferences;Neglecting development and refinement of the mind;Attempting to compel others to believe and live as we do.”

“Hours and days and months and years go by; the past returns no more, and what is to be we cannot know; but whatever the time gives us in which we live, we should therefore be content.”

“We must not say every mistake is a foolish one.”

“What is morally wrong can never be advantageous, even when it enables you to make some gain that you believe to be to your advantage. The mere act of believing that some wrongful course of action constitutes an advantage is pernicious.”

“Nemo enim est tam senex qui se annum non putet posse vivere.(No one is so old as to think that he cannot live one more year.)”

“They who say that we should love our fellow-citizens but not foreigners, destroy the universal brotherhood of mankind, with which benevolence and justice would perish forever”

“The life of the dead is set in the memory of the living.”
