Fundamental ideas play the most essential role in forming a physical theory. Books on physics are full of complicated mathematical formulae. But thought and ideas, not formulae, are the beginning of every physical theory. The ideas must later take the mathematical form of a quantitative theory, to make possible the comparison with experiment.

Definition of design = Everyone designs who devise courses of action aimed at changing existing situations into preferred ones. The intellectual activity that produces material artifacts is no different fundamentally from the one that prescribes remedies for a sick patient or the one that devises a new sales plan for a company or a social welfare policy for a state.

Nonbeing must in some sense be, otherwise what is it that there is not? This tangled doctrine might be nicknamed Plato's beard; historically it has proved tough, frequently dulling the edge of Occam's razor.

The rich man... is always sold to the institution which makes him rich.

Whatever is known to us by consciousness, is known beyond possibility of question. What one sees or feels, whether bodily or mentally, one cannot but be sure that one sees or feels. No science is required for the purpose of establishing such truths; no rules of art can render our knowledge of them more certain than it is in itself. There is no logic for this portion of our knowledge.

If this is the best of possible worlds, what then are the others?

Uncertainty, doubt, perpetual wrestling with the mystery of our final destiny, mental despair, and the lack of any solid and stable foundation, may be the basis of an ethic.

The auspices for philosophy are bad if, when proceeding ostensibly on the investigation of truth, we start saying farewell to all uprightness, honesty and sincerity, and are intent only on passing ourselves off for what we are not. We then assume, like those three sophists [Fichte, Schelling and Hegel], first a false pathos, then an affected and lofty earnestness, then an air of infinite superiority, in order to impose where we despair of ever being able to convince.

We do not know nature; causes hidden in her breast might have produced everything. In your turn, observe the polyp of Trembley: does it not contain in itself the causes which bring about regeneration? Why then would it be absurd to think that there are physical causes by reason of which everything has been made, and to which the whole chain of this vast universe is so necessarily bound and held that, nothing which happens, could have failed to happen,-causes, of which we are so invincibly ignorant that we have had recourse to a God, who, as some aver, is not so much as a logical entity? Thus to destroy chance is not to prove the existence of a supreme being, since there may be some other thing which is neither chance nor God-I mean, nature. It follows that the study of nature can make only unbelievers; and the way of thinking of all its more successful investigators proves this.

A little reflection will show us that every belief, even the simplest and most fundamental, goes beyond experience when regarded as a guide to our actions. ... Even the fundamental "I am," which cannot be doubted, is no guide to action until it takes to itself "I shall be," which goes beyond experience. The question is not, therefore, "May we believe what goes beyond experience?" for this is involved in the very nature of belief; but "How far and in what manner may we add to our experience in forming our beliefs?"

The ultimate goal of the arriviste's aspirations is not to acquire a thing of value, but to be more highly esteemed than others. He merely uses the "thing" as an indifferent occasion for overcoming the oppressive feeling of inferiority which results from his constant comparisons.

Those least responsible for climate change are worst affected by it.

The deepest thinking is humble. It is only concerned that the flame of truth which it keeps alive should burn with the strongest and purest heat; it does not trouble about the distance to which its brightness penetrates.

There is nothing in any object, consider'd in itself, which can afford us a reason for drawing a conclusion beyond it; even after the observation of the frequent or constant conjunction of objects, we have no reason to draw any inference concerning any object beyond those of which we have had experience.

Liberalism... has a left of center meaning in the United States. It has a slightly right of center meaning in much of continental Europe.

Ignorant as regards the unity of man with himself, the world is still more ignorant in respect to the two other unities - unity of man with God and the universe.

Where the preamble declares, that coercion is a departure from the plan of the holy author of our religion, an amendment was proposed by inserting "Jesus Christ," so that it would read "A departure from the plan of Jesus Christ, the holy author of our religion;" the insertion was rejected by the great majority, in proof that they meant to comprehend, within the mantle of its protection, the Jew and the Gentile, the Christian and Mohammedan, the Hindoo and Infidel of every denomination.

For the lesson of such stories [of resistance to Nazi atrocities] is simple and within everybody's grasp. Politically speaking, it is that under conditions of terror, most people will comply but some people will not, just as the lesson of the countries to which the Final Solution was proposed is that "it could happen" in most places but it did not happen everywhere. Humanly speaking, no more is required, and no more can reasonably be asked, for this planet to remain a place fit for human habitation.

You can put this another way by saying that while in other sciences the instruments you use are things external to yourself (things like microscopes and telescopes), the instrument through which you see God is your whole self. And if a man's self is not kept clean and bright, his glimpse of God will be blurred-like the Moon seen through a dirty telescope. That is why horrible nations have horrible religions: they have been looking at God through a dirty lens.

There is a great difference between the Idols of the human mind and the Ideas of the divine. That is to say, between certain empty dogmas, and the true signatures and marks set upon the works of creation as they are found in nature.

The basis of our government being the opinion of the people, the very first object should be to keep that right; and were it left to me to decide whether we should have a government without newspapers, or newspapers without a government, I should not hesitate a moment to prefer the latter. But I should mean that every man should receive those papers and be capable of reading them.

There are two atheisms of which one is a purification of the notion of God.

Big industry, competition and generally the individualistic organization of production have become a fetter which it must and will shatter.

The socialist system of society should only be, and can only be, an historical product, born out of the school of its own experiences, born in the course of its realization, as a result of the developments of living history, which - just like organic nature of which, in the last analysis, it forms a part - has the fine habit of always producing along with any real social need the means to its satisfaction, along with the task simultaneously the solution. However, if such is the case, then it is clear that socialism by its very nature cannot be decreed or introduced by ukase. It has as its prerequisite a number of measures of force - against property, etc. The negative, the tearing down, can be decreed; the building up, the positive, cannot. New Territory. A thousand problems. Only experience is capable of correcting and opening new ways.

If you are a preacher of mercy, do not preach an imaginary but the true mercy. If the mercy is true, you must therefore bear the true, not an imaginary sin. God does not save those who are only imaginary sinners. Be a sinner, and let your sins be strong (sin boldly), but let your trust in Christ be stronger, and rejoice in Christ who is the victor over sin, death, and the world. We will commit sins while we are here, for this life is not a place where justice resides. We, however, says Peter (2. Peter 3:13) are looking forward to a new heaven and a new earth where justice will reign.

But it is better to assume principles less in number and finite, as Empedocles makes them to be. All philosophers... make principles to be contraries... (for Parmenides makes principles to be hot and cold, and these he demominates fire and earth) as those who introduce as principles the rare and the dense. But Democritus makes the principles to be the solid and the void; of which the former, he says, has the relation of being, and the latter of non-being. ...it is necessary that principles should be neither produced from each other, nor from other things; and that from these all things should be generated. But these requisites are inherent in the first contraries: for, because they are first, they are not from other things; and because they are contraries, they are not from each other.

Man cannot be free if he does not know that he is subject to necessity, because his freedom is always won in his never wholly successful attempts to liberate himself from necessity.

I am enraptured by Hindu philosophy, whose essential endeavor is to surmount the self; and everything I do, everything I think is only myself and the selfs humiliations.

I will now confess my own utopia. I devoutly believe in the reign of peace and in the gradual advent of some sort of socialistic equilibrium. The fatalistic view of the war function is to me nonsense, for I know that war-making is due to definite motives and subject to prudential checks and reasonable criticisms, just like any other form of enterprise. And when whole nations are the armies, and the science of destruction vies in intellectual refinement with the science of production, I see that war becomes absurd and impossible from its own monstrosity. Extravagant ambitions will have to be replaced by reasonable claims, and nations must make common cause against them.

Innumerable are the illusions and legerdemain-tricks of Custom: but of all these, perhaps the cleverest is her knack of persuading us that the Miraculous, by simple repetition, ceases to be Miraculous.

Out of love, God becomes man. He says: Here you see what it is to be a human being; but he adds: Take care, for I am also God - blessed is he who takes no offense at me. 

In an autobiography one must surely be allowed to boast, just for fun. I have, at a range of twenty feet, shot the tobacco out of a cigarette and left the paper intact. At a range of thirty feet, I have split a target, edge towards me, with an air pistol. I am also the world's champion in a game called "You Are the Target," in which anyone better than I would be dead. The game is to shoot an arrow straight up and see how near to you it can be allowed to land. You have to watch its fall very carefully, but I have had it hit the ground exactly between my feet. Of course, there were no witnesses. Had there been, they would forcefully have discouraged the experiment. I was using a fifty-five pound bow.

I do what is mine to do; the rest doesn't disturb me.

One right-thinking man thinks like all other right-thinking men of his time-that is to say, in most cases, like some wrong-thinking man of another time.

As the liberal sees it, the task of the state consists solely and exclusively in guaranteeing the protection of life, health, liberty, and private property against violent attacks. Everything that goes beyond this is an evil. A government that, instead of fulfilling its task, sought to go so far as actually to infringe on personal security of life and health, freedom, and property would, of course, be altogether bad.

Not wise does it seem to attempt comprehending and understanding a Human World without full perfected Humanity. No talent must sleep; and if all are not alike active, all must be alert, and not oppressed and enervated. As we see a future Painter in the boy who fills every wall with sketches and variedly adds colour to figure; so we see a future Philosopher in him who restlessly traces and questions all natural things, pays heed to all, brings together whatever is remarkable, and rejoices when he has become master and possessor of a new phenomenon, of a new power and piece of knowledge.

It seldom happens, however, that a great proprietor is a great improver.

The Reformation was a popular uprising, and for a century and a half drenched Europe in blood. The beginnings of the Scientific movement were confined to a minority among the intellectual elite.... The worst that happened to men of science was that Galileo suffered an honorable detention and a mild reproof, before dying peacefully in his bed. The way in which the persecution of Galileo has been remembered is a tribute to the quiet commencement of the most intimate change in outlook which the human race had yet encountered. Since a babe was born in a manger, it may be doubted whether so great a thing has happened with so little stir.

"They would say," he answered, "that you do not fail in obedience through lack of love, but have lost love because you never attempted obedience."

When the changes of our times gave you an opportunity, you restored to the use of man that genius of your father for which he had suffered, and made him in real truth immortal by publishing as an eternal memorial of him those books which that bravest of men had written with his own blood. You have done a great service to Roman literature: a large part of Cordus's books had been burned; a great service to posterity, who will receive a true account of events, which cost its author so dear; and a great service to himself, whose memory flourishes and ever will flourish, as long as men set any value upon the facts of Roman history, as long as anyone lives who wishes to review the deeds of our fathers, to know what a true Roman was like - one who still remained unconquered when all other necks were broken in to receive the yoke of Sejanus, one who was free in every thought, feeling, and act.

Love is a severe critic. Hate can pardon more than love.

To me, believing that some correspondence intrinsically just is reference (not as a result of our operational and theoretical constraints, or our intentions, but as an ultimate metaphysical fact) amounts to a magical theory of reference. Reference itself becomes what Locke called a 'substantial form' (an entity which intrinsically belongs with a certain name) on such a view. Even if one is willing to contemplate such unexplainable metaphysical facts, the epistemological problems that accompany such a metaphysical view seem insuperable. For, assuming a world of mind- independent, discourse-independent entities (this is the presupposition of the view we are discussing), there are, as we have seen, many different 'correspondences' which represent possible or candidate reference relations (infinitely many, in fact, if there are infinitely many things in the universe).

That some have never dreamed is as improbable as that some have never laughed.
