If variations useful to any organic being do occur, assuredly individuals thus characterized will have the best chance of being perserved in the struggle for life; and from the strong principle of inheritance they will tend to produce offsping similarly characterized. This principle of preservation, I have called, for the sake of brevity, Natural Selection.

The principle can be established that for a man who does not cheat what he believes to be true must determine his actions.

That every will must consider every other will its equal — would be a principle hostile to life, an agent of the dissolution and destruction of man, an attempt to assassinate the future of man, a sign of weariness, a secret path to nothingness.

Friedrich Nietzsche

It is incumbent on every generation to pay its own debts as it goes. A principle which if acted on would save one-half the wars of the world.

Thomas Jefferson

Michel de Montaigne

Kings were put to death long before 21 January, 1793, and before the regicides of the nineteenth century. But regicides of earlier times and their followers were interesting in attacking the person, not the principle, of the king. They wanted another king, and that was all. It never occurred to them that the throne could remain empty for ever.

America is today the hope of all honorable men who respect the rights of their fellow men and who believe in the principle of freedom and justice.

Come what may, I am bound to think that all things are ordered for the best; though when the good is a furlong off, and we with our beetle eyes can only see three inches, it takes some confidence in general principles to pull us through.

Arthur Conan Doyle

Long and painful experience has taught me one great principle in managing business for other people, viz., if you want to inspire confidence, give plenty of statistics.

What decides the purpose of life is simply the programme of the pleasure principle. This principle dominates the operation of the mental apparatus from the start. There can be no doubt about its efficacy, and yet its programme is at loggerheads with the whole world, with the macrocosm as much as with the microcosm.

A physical theory is not an explanation. It is a system of mathematical propositions, deduced from a small number of principles, which aim... to represent as simply, as completely, and as exactly as possible a group of experimental laws.

Arthur Conan Doyle

The riddle of life is simply this. For some mad reason in this mad world of ours, the things which men differ about most are exactly the things about which they must be got to agree. Men can agree on the fact that the earth goes round the sun. But then it does not matter a dump whether the earth goes around the sun or the Pleiades. But men cannot agree about morals: sex, property, individual rights, fixity and contracts, patriotism, suicide, public habits of health – these are exactly the things that men tend to fight about. And these are exactly the things that must be settled somehow on strict principles. Study each of them, and you will find each of them works back certainly to a philosophy, probably to a religion.

G. K. Chesterton

And in my own life, in this country, and as President, I have learned that our identities do not have to be defined by putting someone else down, but can be enhanced by lifting somebody else up. They don't have to be defined in opposition to others, but rather by a belief in liberty and equality and justice and fairness. [...] But my faith in those principles does force me to expand my moral imagination and to recognize that I can best serve my own people, I can best look after my own daughters, by making sure that my actions seek what is right for all people and all children, and your daughters and your sons.

There is a point, of course, where a man must take the isolated peak and break with all his associates for clear principle; but until that time comes he must work, if he would be of use, with men as they are. As long as the good in them overbalances the evil, let him work with them for the best that can be obtained.

Theodore Roosevelt

Our real battlefield today is Asia and our real battle is the one between democracy and communism.... We have to prove to the world and particularly to downtrodden areas of the world which are the natural prey to the principles of communist economics that democracy really brings about happier and better conditions for the people as a whole.

Eleanor Roosevelt

In the past, the respect people had for religion meant that ethical practice was maintained through a majority following one religion or another. But this is no longer the case. We must therefore find some other way of establishing basic ethical principles.

Tenzin Gyatso, 14th Dalai Lama

The several states composing the United States of America are not united on the principle of unlimited submission to their general government

Thomas Jefferson

Do not the Rays of Light which fall upon Bodies, and are reflected or refracted, begin to bend before they arrive at the Bodies; and are they not reflected, refracted, and inflected, by one and the same Principle, acting variously in various Circumstances?

Non-cooperation in military matters should be an essential moral principle for all true scientists...

Albert Einstein

But my understanding is there are many villages you go to where there's really no schools, as a practical matter, and many of the schools still teach just how to memorize certain things rather than how to think critically about problems. And every country at this point, if it wants to succeed, needs to put in place free, compulsory education for its young people — because they just can't succeed unless they have some basic skills. They have to be able to read. They have to be able to do mathematics. They have to have some familiarity with computers. They have to be able to understand basic principles of science. If you don't have those basic tools, then it's very hard to find a decent job in today's economy.

I think a man ought to get drunk at least twice a year just on principle, so he won't let himself get snotty about it.

Raymond Chandler

Through the principle of associated habit, the same movements of the face and eyes are practised, and can, indeed, hardly be avoided, whenever we know or believe that others are blaming, or too strongly praising, our moral conduct.

The machines that are first invented to perform any particular movement are always the most complex, and succeeding artists generally discover that, with fewer wheels, with fewer principles of motion, than had originally been employed, the same effects may be more easily produced. The first systems, in the same manner, are always the most complex.

An opponent is entitled to the same regard for his principles as we would expect others to have for ours. Non-violence demands that we should see every opportunity to win over opponents.
