John Adams,ca. 1821 by Gilbert Stuart. National Gallery of Art.

“Government is instituted for the common good; for the protection, safety, prosperity, and happiness of the people; and not for profit, honor, or private interest of any one man, family, or class of men; therefore, the people alone have an incontestable, unalienable, and indefeasible right to institute government; and to reform, alter, or totally change the same, when their protection, safety, prosperity, and happiness require it.” — John Adams, Thoughts on Government, 1776

“All great things are simple, and many can be expressed in single words: freedom, justice, honor, duty, mercy, hope.” — Winston Churchill

This one immediately made me think of Mr. Hopey/Changey:

“A rough style with truth is preferable to eloquence without it.” — Cadwallader Colden
