What madness this is, to punish oneself because one is unfortunate, and not to lessen, but to increase one's ills! You ought to display, in this matter also, that decent behaviour and modesty which has characterised all your life: for there is such a thing as self-restraint in grief also.

It cannot at this time be too often repeated; line upon line; precept upon precept; until it comes into the currency of a proverb, To innovate is not to reform.

The most simple picture one can form about the creation of an empirical science is along the lines of an inductive method. Individual facts are selected and grouped together such that their lawful connection becomes clearly apparent. ... The truly great advances in our understanding of nature originated in a manner almost diametrically opposed to induction. The intuitive grasp of the essentials or a large complex of facts leads the scientist to the postulation of a hypothetical basic law, or several such basic laws. From the basic laws (system of axioms) he derives his conclusions as completely as possible in a purely logically deductive manner. These conclusions, derived from the basic laws (and often only after time-consuming developments and calculations), can then be compared to experience, and in this manner provide criteria for the justification of the assumed basic law.

In the presence of the total reality upon which our conduct is founded, our knowledge is characterized by peculiar limitations and aberrations. We cannot say in principle that "error is life and knowledge is death," because a being involved in persistent errors would continually act wide of the purpose, and would thus inevitably perish.

The standard that I always come back to is the health of the world, which is the same as our own personal health. We can't distinguish our health from the health of everything else. And we know enough from the ecologists now to know that health is a very complex and un-understandable complexity of relationships that makes the world whole.

The original thinking force of the universe progresses and develops itself in all possible determinations of which it is capable, just as the other original natural forces progress and assume all possible configurations. I am a particular determination of the formative force, like the plant; a particular determination of the peculiar motive force, like the animal; and in addition to this a determination of the thinking force: and the union of these three basic forces into one force, into one harmonious development, is the distinguishing characteristic of my species.

There as here, passions are the motive of all action, but they are livelier, more ardent, or merely simpler and purer, thereby assuming a totally different character. All the first movements of nature are good and right.

In my fiction I am careful to make everything probable and to tie up all loose ends. Real life is not hampered by such considerations.

There is but one indefectibly certain truth, and that is the truth that pyrrhonistic scepticism itself leaves standing, - the truth that the present phenomenon of consciousness exists.

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.

In adversity, remember to keep an even mind.

Scientific theories are distinguished from myths... in being criticizable, and... open to modifications... They can be neither verified nor probabilified.

Mechanical Science depends on the Conception of Force; and is divided into 'Statics', the doctrine of Force preventing motion, and 'Dynamics', the doctrine of Force producing motion.

Even in the games of children there are things to interest the greatest mathematician.

In the process of decision those alternatives are chosen which are considered to be appropriate means of reaching desired ends. Ends themselves, however, are often merely instrumental to more final objectives. We are thus led to the conception of a series, or hierarchy, of ends. Rationality has to do with the construction of means-ends chains of this kind.

He who is in love is wise and is becoming wiser, sees newly every time he looks at the object beloved, drawing from it with his eyes and his mind those virtues which it possesses.

Revolutionaries do not make revolutions! The revolutionaries are those who know when power is lying in the street and when they can pick it up. Armed uprising by itself has never yet led to revolution.

The sentiment of reality can indeed attach itself so strongly to our object of belief that our whole life is polarized through and through, so to speak, by its sense of the existence of the thing believed in, and yet that thing, for the purpose of definite description, can hardly be said to be present to our mind at all.

Men became scientific because they expected law in Nature; and they expected law in Nature because they believed in a Legislator.

So rolling time changes the seasons of things. What was of value, becomes in turn of no worth.

Show me someone who is ill and yet happy, in danger and yet happy, dying and yet happy, exiled and yet happy. Show me such a person; by the gods, how greatly I long to see a Stoic!

We need better government, no doubt about it. But we also need better minds, better friendships, better marriages, better communities.

There are a thousand hacking at the branches of evil to one who is striking at the root, and it may be that he who bestows the largest amount of time and money on the needy is doing the most by his mode of life to produce that misery which he strives in vain to relieve.

I need not repeat, that the most savage of the savage tribes in the forest, live among each other in amity. Lions show no fierceness to the lion race. The boar does not brandish his deadly tooth against his brother boar. The lynx lives in peace with the lynx. The serpent shews no venom in his intercourse with his fellow serpent; and the loving kindness of wolf to wolf is proverbial.

The will is the living principle of the rational soul, is indeed itself reason, when purely and simply apprehended. That reason is itself active, means, that the pure will, as such, rules and is effectual. The infinite reason alone lies immediately and entirely in the purely spiritual order. The finite being lives necessarily at the same time in a sensuous order; that is to say, in one which presents to him other objects than those of pure reason; a material object, to be advanced by instruments and powers, standing indeed under the immediate command of the will, but whose efficacy is conditional also on its own natural laws.

The way in which the vast mass of the poor are treated by modern society is truly scandalous. They are herded into great cities where they breathe a fouler air than in the countryside which they have left.

In history, we are concerned with what has been and what is; in philosophy, however, we are concerned not with what belongs exclusively to the past or to the future, but with that which is, both now and eternally - in short, with reason.

People do not go into the company of their fellow-creatures for what would seem a very sufficient reason, namely, that they have something to say to them, or something that they want to hear from them; but in the vague hope that they may find something to say.

The more you live, the less useful it seems to have lived.

The best life is the one in which the creative impulses play the largest part and the possessive impulses the smallest.

It is not by change of place that we can come nearer to Him who is in every place, but by the cultivation of pure desires and virtuous habits.

There is nothing outside the text," which Derrida opponents have characterized to mean that nothing exists but language.

The general fellowship of our human situation has been rendered even more dubious than before, inasmuch as, though the old ties of caste have been loosened, a new restriction of the individual to some prescribed status in society is manifest. Less than ever, perhaps, is it possible for a man to transcend the limitations imposed by his social origins.

The aspects of things that are most important for us are hidden because of their simplicity and familiarity. (One is unable to notice something - because it is always before one's eyes.) The real foundations of his enquiry do not strike a man at all. Unless that fact has at some time struck him. - And this means: we fail to be struck by what, once seen, is most striking and most powerful.

At the parting of ways in the life-order, where the question is between the new creation or decay, that man will be decisive for new creation who is able on his own initiative to seize the helm and steer a course of his own choosing - even if that course be opposed to the will of the masses. Should the emergence of such persons become impossible a lamentable shipwreck will be inevitable.

It is absurd ... to hope that maybe another Newton may some day arise, to make intelligible to us even the genesis of but a blade of grass

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.

Our patriotism comes straight from the Romans. This is why French children are encouraged to seek inspiration for it in Corneille. It is a pagan virtue, if these two words are compatible. The word pagan, when applied to Rome, early possesses the significance charged with horror which the early Christian controversialists gave it. The Romans really were an atheistic and idolatrous people; not idolatrous with regard to images made of stone or bronze, but idolatrous with regard to themselves. It is this idolatry of self which they have bequeathed to us in the form of patriotism.

All human activity is prompted by desire. There is a wholly fallacious theory advanced by some earnest moralists to the effect that it is possible to resist desire in the interests of duty and moral principle. I say this is fallacious, not because no man ever acts from a sense of duty, but because duty has no hold on him unless he desires to be dutiful. If you wish to know what men will do, you must know not only, or principally, their material circumstances, but rather the whole system of their desires with their relative strengths.

Nonviolence is perhaps best described as a practice of resistance that becomes possible, if not mandatory, precisely at the moment when doing violence seems most justified and obvious. In this way, it can be understood as a practice that not only stops a violent act, or a violent process, but requires a form of sustained action, sometimes aggressively pursued. So, one suggestion I will make is that we can think of nonviolence not simply as the absence of violence, or as the act of refraining from committing violence, but as a sustained commitment, even a way of rerouting aggression for the purposes of affirming ideals of equality and freedom.

Does anything genuinely beautiful need supplementing? No more than justice does-or truth, or kindness, or humility. Are any of those improved by being praised? Or damaged by contempt? Is an emerald suddenly flawed if no one admires it? Or gold, or ivory, or purple? Lyres? Knives? Flowers? Bushes?

Among all the great men who have philosophized about this remarkable effect, I am more astonished at Kepler than at any other. Despite his open and acute mind, and though he has at his fingertips the motions attributed to the earth, he nevertheless lent his ear and his assent to the moon's dominion over the waters, to occult properties, and to such puerilities.

I am well aware of how anarchic much of what I say may sound. Expressing myself thus abstractly and briefly, I may seem to despair of the very notion of truth. But I beseech you to reserve your judgment until we see it applied to the details which lie before us. I do indeed disbelieve that we or any other mortal men can attain on a given day to absolutely incorrigible and unimprovable truth about such matters of fact as those with which religions deal. But I reject this dogmatic ideal not out of a perverse delight in intellectual instability. I am no lover of disorder and doubt as such. Rather do I fear to lose truth by this pretension to possess it already wholly.

But what we've got going wrong is we've got a kind of bifurcation in cultural development:You take your classified telephone directory, and open up "Churches", and have a ruler in your hand. And you will find that the longest space is occupied by authoritarian, Bible-banging churches. And these people are barbarians, who take the written word of the Bible literally. Because they need terribly, they have a personal need, for something to depend on. ... The government realizes that there is a very large number of people like that; and therefore, to keep their votes, they have to pander to those kind of people. And these are the boys who never grew up; they always need Papa. ... The trouble is that the boys who need Papa, are violent. They have the guns. And they are the types of people who like to be soldiers, policemen-tough guys. And therefore they have a great deal of power.

Never give way to melancholy; resist it steadily, for the habit will encroach.

We measure the earth, sun, stars, and ocean depths. We burrow into the depths of the earth for gold. We search for rivers and mountains on the moon. We discover new stars and know their magnitudes. We sound the depths of gorges and build clever machines. Each day brings a new invention. What don't we think of! What can't we do! But there is something else, the most important thing of all, that we are missing. We do not know exactly what it is. We are like a small child who knows he does not feel well but cannot explain why. We are uneasy, because we know a lot of superfluous facts; but we do not know what is really important-ourselves.

Nothing can be preserved that is not good.
