"when the people become ignorant and corrupt"

"The Government has been in the hands of the people. To the people, therefore, and to the faithful and able depositaries of their trust is the credit due. Had the people of the United States been educated in different principles had they been less intelligent, less independent, or less virtuous can it be believed that we should have maintained the same steady and consistent career or been blessed with the same success? While, then, the constituent body retains its present sound and healthful state everything will be safe. They will choose competent and faithful representatives for every department. It is only when the people become ignorant and corrupt, when they degenerate into a populace, that they are incapable of exercising the sovereignty. Usurpation is then an easy attainment, and an usurper soon found. The people themselves become the willing instruments of their own debasement and ruin. Let us, then, look to the great cause, and endeavor to preserve it in full force. Let us by all wise and constitutional measures promote intelligence among the people as the best means of preserving our liberties." - President James Monroe
