"I know of no country in which the love of money has taken stronger hold on the affections of men, and in which the passion for physical gratification is more general than in America."

"The American has no past; he has only the present and the future. He lives in a perpetual state of creation; he is forever building, forever destroying, forever renewing."

"The greatest danger that threatens modern nations is the indifference of the majority to the public interest."

"I have always believed that the love of truth is the most powerful of all passions."

"The most dangerous of all errors is to believe that there is no error."
