Thucydides

“The secret to happiness is freedom... And the secret to freedom is courage.”

“History is Philosophy teaching by example.”

“Ignorance is bold and knowledge reserved.”

“Men's indignation, it seems, is more excited by legal wrong than by violent wrong the first looks like being cheated by an equal, the second like being compelled by a superior.”

“Men naturally despise those who court them, but respect those who do not give way to them.”

“Be convinced that to be happy means to be free and that to be free means to be brave. Therefore do not take lightly the perils of war.”
