“Americanism means the virtues of courage, honor, justice, truth, sincerity, and hardihood—the virtues that made America. The things that will destroy America are prosperity-at-any-price, peace-at-any-price, safety-first instead of duty-first, the love of soft living and the get-rich-quick theory of life.”
Theodore Roosevelt
“Sincerity and truth are the basis of every virtue.”
Confucius
“The first virtue of all really great men is that they are sincere”
Anatole France
“The true hypocrite is the one who ceases to perceive his deception, the one who lies with sincerity”
Andre Gide
“How can sincerity be a condition of friendship? A taste for truth at any cost is a passion which spares nothing.”
Albert Camus
“Fear is not in the habit of speaking truth; when perfect sincerity is expected, perfect freedom must be allowed; nor has anyone who is apt to be angry when he hears the truth any cause to wonder that he does not hear it.”
Publius Cornelius Tacitus
“Five things constitute perfect virtue: gravity, magnanimity, earnestness, sincerity, kindness”
