John Adams on Enlightenment (spiritual)

“The world grows more enlightened. Knowledge is more equally diffused. Newspapers, magazines, and circulating libraries have made mankind wiser. Titles and distinctions, ranks and orders, parade and ceremony, are all going out of fashion.”

“Killing one tyrant only makes way for worse, unless the people have sense, spirit and honesty enough to establish and support a constitution guarded at all points against the tyranny of the one, the few, and the many. Let it be the study, therefore, of lawgivers and philosophers, to enlighten the people's understandings and improve their morals, by good and general education; to enable them to comprehend the scheme of government, and to know upon what points their liberties depend; to dissipate those vulgar prejudices and popular superstitions that oppose themselves to good government; and to teach them that obedience to the laws is as indispensable in them as in lords and kings.”
