What do we mean by saying that existence precedes essence? We mean that man first of all exists, encounters himself, surges up in the world – and defines himself afterwards. If man as the existentialist sees him is not definable, it is because to begin with he is nothing. He will not be anything until later, and then he will be what he makes of himself. Thus, there is no human nature, because there is no God to have a conception of it. Man simply is. Not that he is simply what he conceives himself to be, but he is what he wills, and as he conceives himself after already existing – as he wills to be after that leap towards existence. Man is nothing else but that which he makes of himself. That is the first principle of existentialism.

Jean-Paul Sartre

If you want to find out anything from the theoretical physicists about the methods they use, I advise you to stick closely to one principle: don't listen to their words, fix your attention on their deeds. To him who is a discoverer in this field the products of his imagination appear so necessary and natural that he regards them, and would like to have them regarded by others, not as creations of thought but as given realities.

Albert Einstein

When a man says he approves of something in principle, it means he hasn't the slightest intention of putting it into practice.

Otto von Bismarck

While the principles of our Constitution give just latitude to inquiry, every citizen faithful to it will deem embodied expressions of discontent and open outrages of law and patriotism as dishonorable as they are injurious

Thomas Jefferson

But the most brilliant propagandist technique will yield no success unless one fundamental principle is borne in mind constantly and with unflagging attention. It must confine itself to a few points and repeat them over and over. Here, as so often in this world, persistence is the first and most important requirement for success.

The steady character of our countrymen is a rock to which we may safely moor; and notwithstanding the efforts of the papers to disseminate early discontents, I expect that a just, dispassionate and steady conduct, will at length rally to a proper system the great body of our country. Unequivocal in principle, reasonable in manner, we shall be able I hope to do a great deal of good to the cause of freedom & harmony.

Thomas Jefferson

Combinations of wickedness would overwhelm the world, by the advantage which licentious principles afford, did not those who have long practised perfidy grow faithless to each other.

Cubism is no different from any other school of painting. The same principles and the same elements are common to all. The fact that for a long time cubism has not been understood and that even today there are people who cannot see anything in it, means nothing. I do not read English, and an English book is a blank to me. This does not mean that the English language does not exist, and why should I blame anyone but myself if I cannot understand what I know nothing about?

I am persuaded myself that the good sense of the people will always be found to be the best army. They may be led astray for a moment, but will soon correct themselves. The people are the only censors of their governors; and even their errors will tend to keep these to the true principles of their institution.

Thomas Jefferson

Change your opinions, keep to your principles; change your leaves, keep intact your roots.

We are living in what the Greeks called the right time for a "metamorphosis of the gods," i. e. of the fundamental principles and symbols. This peculiarity of our time, which is certainly not of our conscious choosing, is the expression of the unconscious man within us who is changing. Coming generations will have to take account of this momentous transformation if humanity is not to destroy itself through the might of its own technology and science.

This [experimentation] is the custom—and properly so—in those sciences where mathematical demonstrations are applied to natural phenomena, as is seen in the case of perspective, astronomy, mechanics, music, and others where the principles, once established by well-chosen experiments, become the foundations of the entire superstructure.

Galileo Galilei

Morality is thus the relation of actions to the autonomy of the will, that is, to a possible giving of universal law through its maxims. An action that can coexist with the autonomy of the will is permitted; one that does not accord with it is forbidden. A will whose maxims necessarily harmonize with the laws of autonomy is a holy, absolutely good will. The dependence upon the principle of autonomy of a will that is not absolutely good (moral necessitation) is obligation. This, accordingly, cannot be attributed to a holy being. The objective of an action from obligation is called duty.

In the same manner as we are cautioned by religion to show our faith by our works we may very properly apply the principle to philosophy, and judge of it by its works; accounting that to be futile which is unproductive, and still more so, if instead of grapes and olives it yield but the thistle and thorns of dispute and contention.

All human actions are equivalent... and... all are on principle doomed to failure.

Jean-Paul Sartre

Our experience hitherto justifies us in trusting that nature is the realization of the simplest that is mathematically conceivable. I am convinced that purely mathematical construction enables us to find those concepts and those lawlike connections between them that provide the key to the understanding of natural phenomena. Useful mathematical concepts may well be suggested by experience, but in no way can they be derived from it. Experience naturally remains the sole criterion of the usefulness of a mathematical construction for physics. But the actual creative principle lies in mathematics. Thus, in a certain sense, I take it to be true that pure thought can grasp the real, as the ancients had dreamed.

Albert Einstein

In life, as in a football game, the principle to follow is: Hit the line hard.

Theodore Roosevelt

We set ourselves the ultimate aim of abolishing the state, i. e., all organized and systematic violence, all use of violence against people in general. We do not expect the advent of a system of society in which the principle of subordination of the minority to the majority will not be observed.
In striving for socialism, however, we are convinced that it will develop into communism and, therefore, that the need for violence against people in general, for the subordination of one man to another, and of one section of the population to another, will vanish altogether since people will become accustomed to observing the elementary conditions of social life without violence and without subordination.

I consider Paine our greatest political thinker. As we have not advanced, and perhaps never shall advance, beyond the Declaration and Constitution, so Paine has had no successors who extended his principles. Although the present generation knows little of Paine's writings, and although he has almost no influence upon contemporary thought, Americans of the future will justly appraise his work. I am certain of it.
Truth is governed by natural laws and cannot be denied. Paine spoke truth with a peculiarly clear and forceful ring. Therefore time must balance the scales.

'As a man who knows how to make his education into a rule of life not a means of showing off; who can control himself and obey his own principles.' The true mirror of our discourse is the course of our lives.

Michel de Montaigne

To understand oneself in existence is the Christian principle, except that this self has received much richer and much more profound qualifications that are even more difficult to understand together with existing. The believer is a subjective thinker, and the difference, is only between the simple person and the simple wise person. Here again the oneself is not humanity in general, subjectivity in general, and other such things, whereas everything becomes easy inasmuch as the difficulty is removed and the whole matter is shifted over into the shadow play of abstraction.

Søren Kierkegaard

The task of Government is that of application and encouragement. A wise Government seeks to provide the opportunity through which the best of individual achievement can be obtained, while at the same time it seeks to remove such obstruction, such unfairness as springs from selfish human motives. Our common life under our various agencies of Government, our laws and our basic Constitution, exist primarily to protect the individual, to cherish his rights and to make clear his just principles.

Franklin D. Roosevelt

Christian principles are, admittedly, stricter than the others; but then we think you will get help towards obeying them which you will not get towards obeying the others.

If the colleges were better, if they … had the power of imparting valuable thought, creative principles, truths which become powers, thoughts which become talents, — if they could cause that a mind not profound should become profound, — we should all rush to their gates: instead of contriving inducements to draw students, you would need to set police at the gates to keep order in the in-rushing multitude.

Ralph Waldo Emerson

Don't interfere with anything in the Constitution. That must be maintained, for it is the only safeguard of our liberties. And not to Democrats alone do I make this appeal, but to all who love these great and true principles.

Abraham Lincoln
