Thomas Jefferson (17431826)
Believing that the happiness of mankind is best promoted by the useful pursuits of peace, that on these alone a stable prosperity can be founded, that the evils of war are great in their endurance, and have a long reckoning for ages to come, I have used my best endeavors to keep our country uncommitted in the troubles which afflict Europe, and which assail us on every side.
