“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.”

“To be content with what we possess is the greatest and most secure of riches.”

“If we are not ashamed to think it, we should not be ashamed to say it.”

“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.”

“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”

“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.)”

“Not to know what has been transacted in former times is to be always a child. If no use is made of the labours of past ages, the world must remain always in the infancy of knowledge.”
