Such is the infatuation of self-love, that, though in general doctrine of the vanity world all men agree, yet almost everyone flatters himself that his own case is to be an exception from the common rule.

I venerate the man whose heart is warm, whose hands are pure, whose doctrine and whose life, coincident, exhibit lucid proof that he is honest in the sacred cause.

Our doctrine here is therefore that all reality... is brought forth solely by the imagination.

Justice is immortal, eternal, and immutable, like God Himself; and the development of law is only then a progress when it is directed towards those principles which always like Him, are eternal; and whenever prejudice of error succeeds in establishing in customary law any doctrine contrary to eternal justice.

We are not asking our children to do their own best but to be the best. Education is in danger of becoming a religion based on fear; its doctrine is to compete. The majority of our children are being led to believe that they are doomed to failure in a world which has room only for those at the top.

The doctrine of equality!... But there exists no more poisonous poison: for it seems to be preached by justice itself, while it is the end of justice... ‘Equality for equals, inequality for unequals’ - that would be the true voice of justice: and, what follows from it, ‘Never make equal what is unequal’.

The real value of any doctrine can only be determined by its influence on the conduct of man, with respect to himself, to his fellow-creatures, or to God.

Too many follow example rather than precept; but it is safer to learn rather from precept than example. Man a wise teacher does not follow his own teaching; for it is easier to say, do this, than to do it. If then I see good doctrine with an evil life, though I pity the last, I will follow the first. Good sayings belong to all; evil actions only to their authors.

Truth is the disciple of the ascetic, the quest of the mystic, the faith of the simple, the ransom of the weak, the standard of the righteous, the doctrine of the meek, and the challenge of Nature. Together, all these constitute the Law of the Universe.

We conclude that in the field of public education the doctrine of “separate but equal” has no place. Separate educational facilities are inherently unequal. Therefore, we hold that the plaintiffs and others similarly situated for whom the actions have been brought are, by reason of the segregation complained of, deprived of the equal protection of the laws guaranteed by the Fourteenth Amendment.

The doctrine that the world is made up of objects whose existence is independent of human consciousness turns out to be in conflict with quantum mechanics and the facts established by experiment.

The doctrine of foods is of great ethical and political significance. Food becomes blood, blood becomes heart and brain, thought and mind stuff. Human fare is the foundation of human culture and thought. Would you improve the people? Give them, instead of declamations against sin, better food. Man is what he eats.

To ask for overt renunciation of a cherished doctrine is to expect too much of human nature. Men do not repudiate the doctrines and dogma to which they have sworn their loyalty. Instead they rationalize, revise, and reinterpret them to meet new needs and new circumstances, all the while protesting that their heresy is the purest orthodoxy.

The essential ingredient of democracy is not doctrine but intelligence, not authority but reason, not cynicism but faith in men, faith in God. Our strength lies in the fearless pursuit of truth by the minds of men who are free.

Live to explain thy doctrine by thy life.

For when man comes to front the everlasting God, and look the splendor of His judgments in the face, personal integrity, the dream of spotlessness and innocence, vanishes into thin air: your decencies and your church-goings and your regularities and your attachment to a correct school and party, your gospel formulas of sound doctrine - what is all that, in front of the blaze of the wrath to come?

Authority is properly the servant of justice, and political powers are arbitrary and illegitimate if not based upon qualification for that service. This is the doctrine of the ethical derivation of authority or public power, as opposed to that of an unconditioned and inherent sovereignty.

Philosophy is not a body of doctrine but an activity.

Do not believe what your teacher tells you merely out of respect for the teacher. But whatsoever, after due examination and analysis, you find to be conducive to the good, the benefit, the welfare of all beings – that doctrine believe and cling to, and take it as your guide.

If there were a good cause for believing that the earth would be uninhabitable in A.D. 2000 or 2100 the doctrine of Progress would lose its meaning and would automatically disappear.
