"[I]t is Religion and Morality alone, which can establish the Principles upon which Freedom can securely stand....The only foundation of a free Constitution, is pure Virtue, and if this cannot be inspired into our People, in a great Measure, than they have it now, They may change their Rulers, and the forms of Government, but they will not obtain a lasting Liberty."
-- John Adams, letter to Zabdiel Adams, 21 June 1776
