“When the doctrine of allegiance to party can utterly up-end a man's moral constitution and make a temporary fool of him besides, what excuse are you going to offer for preaching it, teaching it, extending it, perpetuating it? Shall you say, the best good of the country demands allegiance to party? Shall you also say it demands that a man kick his truth and his conscience into the gutter, and become a mouthing lunatic, besides?”
Mark Twain
“As a matter of traditional and sound constitutional doctrine, an amendment to the Constitution should be the last resort when all other measures have proved inadequate.”
Arlen Specter
“My doctrine is not a doctrine but just a vision. I have not given you any set rules, I have not given you a system.”
Buddha
“Nearly all the philosophical and mathematical doctrines attributed to Pythagoras are derived from India”
Ludwig von Schroder
“I think a man's duty is to find out where the truth is, or if he cannot, at least to take the best possible human doctrine and the hardest to disprove, and to ride on this like a raft over the waters of life”
Plato
“Many a doctrine is like a window pane. We see truth through it but it divides us from truth.”
Kahlil Gibran
“The older I grow the more I distrust the familiar doctrine that age brings wisdom.”
Henry Louis Mencken
