I maintain that in every special natural doctrine only so much science proper is to be met with as mathematics; for... science proper, especially of nature, requires a pure portion, lying at the foundation of the empirical, and based upon à priori knowledge of natural things. ...the conception should be constructed. But the cognition of the reason through construction of conceptions is mathematical. A pure philosophy of nature in general, namely, one that only investigates what constitutes a nature in general, may thus be possible without mathematics; but a pure doctrine of nature respecting determinate natural things (corporeal doctrine and mental doctrine), is only possible by means of mathematics; and as in every natural doctrine only so much science proper is to be met with therein as there is cognition à priori, a doctrine of nature can only contain so much science proper as there is in it of applied mathematics.

Poets and priests were one in the beginning, and they only separated in later times. But the real poet is always a priest, just as the real priest always remains a poet.

The Autarch maintained his indifferent calm, but a certain lack of certainty was gathering, and he did not like to experience a lack of certainty. He liked nothing which made him aware of limitations. An Autarch should have no limitations, and on Lingane he had none that natural law did not impose.

It may be confidently asserted that no man chooses evil because it is evil; he only mistakes it for happiness, the good he seeks. And the desire of rectifying these mistakes, is the noble ambition of an enlightened understanding, the impulse of feelings that Philosophy invigorates.

The electronic age is a world in which causes and effects become almost interchangeable, as in music structures.

That which I am now entering upon being the Consideration of the things themselves whereinto Spagyrists resolve mixt Bodies by the Fire, If I can shew that these are not of an Elementary Nature, it will be no great matter what names these or those Chymists have been pleased to give them. And I question not that to a Wise man, and consequently to Eleutherius, it will be lesse considerable to know, what Men Have thought of Things, then what they Should have thought.

If man in the state of nature be so free, as has been said; if he be absolute lord of his own person and possessions, equal to the greatest, and subject to no body, why will he part with his freedom, this empire, and subject himself to the dominion and control of any other power?

Law and arbitrary power are in eternal enmity. Name me a magistrate, and I will name property; name me power, and I will name protection. It is a contradiction in terms, it is blasphemy in religion, it is wickedness in politics, to say that any man can have arbitrary power. In every patent of office the duty is included. For what else does a magistrate exist? To suppose for power is an absurdity in idea. Judges are guided and governed by the eternal laws of justice, to which we are all subject. We may bite our chains, if we will, but we shall be made to know ourselves, and be taught that man is born to be governed by law; and he that will substitute will in the place of it is an enemy to God.

The young today cannot follow narrative but they are alert to drama. They cannot bear description but they love landscape and action.

In science men have discovered an activity of the very highest value in which they are no longer, as in art, dependent for progress upon the appearance of continually greater genius, for in science the successors stand upon the shoulders of their predecessors; where one man of supreme genius has invented a method, a thousand lesser men can apply it.

Scientists believe there is a hierarchy of facts and that among them may be made a judicious choice. They are right, since otherwise there would be no science...

As long as I can remember, I have suffered because of the great misery I saw in the world. I never really knew the artless, youthful joy of living, and I believe that many children feel this way, even when outwardly they seem to be wholly happy and without a single care.

Reductionism (ultimately, the empirical explanability of everything and a cornerstone of science), has uses that are appropriate, and it also can be used inappropriately. It is appropriately used as a way (one way) of understanding what is empirically known or empirically knowable. When it becomes merely an intellectual "position" confronting what is not empirically known or knowable, then it becomes very quickly absurd, and also grossly desensitizing and false.

Wars have never made peace or preserved it or fostered its ideals. To have peace you must make peace with your enemy. To make peace only with your friends is to avoid the issue, and to permit a great principle to become absurd. Far from making peace, wars invariably serve as classrooms and laboratories where men and techniques and states of mind are prepared for the next war.

The man is making preparations for a year, and does not know that he will die before evening. And I remembered God's second saying, "Learn what is not given to man." 'What dwells in man" I already knew. Now I learnt what is not given him. It is not given to man to know his own needs.

When the basic structure of society is publicly known to satisfy its principles for an extended period of time, those subject to these arrangements tend to develop a desire to act in accordance with these principles and to do their part in institutions which exemplify them.

Man is a sun and his senses are the planets.

The man who renounces himself, comes to himself.

To entire sincerity there belongs ceaselessness. Not ceasing, it continues long. Continuing long, it evidences itself. Evidencing itself, it reaches far. Reaching far, it becomes large and substantial. Large and substantial, it becomes high and brilliant. Large and substantial; this is how it contains all things. High and brilliant; this is how it overspreads all things. Reaching far and continuing long; this is how it perfects all things. So large and substantial, the individual possessing it is the co-equal of Earth. So high and brilliant, it makes him the co-equal of Heaven. So far-reaching and long-continuing, it makes him infinite. Such being its nature, without any display, it becomes manifested; without any movement, it produces changes; and without any effort, it accomplishes its ends.

"My field," said Goethe, "is time." That is indeed the absurd speech. What, in fact, is the Absurd Man? He who, without negating it, does nothing for the eternal. Not that nostalgia is foreign to him. But he prefers his courage and his reasoning. The first teaches him to live without appeal and to get along with what he has; the second informs him of his limits. Assured of his temporally limited freedom, of his revolt devoid of future, and of his mortal consciousness, he lives out his adventure within the span of his lifetime.

If some great Power would agree to make me always think what is true and do what is right, on condition of being turned into a sort of clock and wound up every morning before I got out of bed, I should instantly close with the offer. The only freedom I care about is the freedom to do right; the freedom to do wrong I am ready to part with on the cheapest terms to any one who will take it of me.

The noblest people are those despising wealth, learning, pleasure and life; esteeming above them poverty, ignorance, hardship and death.

On the whole, ought I not to rejoice that God was pleased to give me such a father; that from earliest years I had the example of a real man of God's own making continually before me? Let me learn of him. Let me write my books as he built his houses, and walk as blamelessly through this shadow world; if God so will, to rejoin him at last. Amen.

An individual may perceive a way of life, or a method of social organisation, by which more of the desires of mankind could be satisfied than under the existing method. If he perceives truly, and can persuade men to adopt his reform, he is justified. Without rebellion, mankind would stagnate, and injustice would be irremediable.

Boasting, like gilded armour, is very different inside from outside.

The labour-power is a commodity, not capital, in the hands of the labourer, and it constitutes for him a revenue so long as he can continuously repeat its sale; it functions as capital after its sale, in the hands of the capitalist, during the process of production itself.

One naturally regrets not being an expert or one of those insiders who thoroughly understand. It's hell to be an amateur. A little reflection calms your sorrow, however. The experts in their own little speedboat, the rest of us floating with the rest of mankind in a great barge - that is the picture.

It is too early to love. We will buy the right to do so by shedding blood.

Let him sensibly perceive, that the kindness he shews to others, is no ill husbandry for himself; but that it brings a return in kindness both from those that receive it, and those who look on. Make this a contest among children, who shall out-do one another in this way: and by this means, by a constant practise, children having made it easy to themselves to part with what they have, good nature may be settled in them into a habit, and they may take pleasure, and pique themselves in being kind, liberal and civil, to others.

Make yourself necessary to somebody. Do not make life hard to any.

Abbot Terrasson tells us that if the size of a book were measured not by the number of its pages but by the time required to understand it, then we could say about many books that they would be much shorter were they not so short.

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.

If you are not already dead, forgive. Rancor is heavy, it is worldly; leave it on earth: die light.

There's nothing like deduction. We've determined everything about our problem but the solution.

As medium for reaching understanding, speech acts serve: a) to establish and renew interpersonal relations, whereby the speaker takes up a relation to something in the world of legitimate social orders; b) to represent states and events, whereby the speaker takes up a relation to something in the world of existing states of affairs; c) to manifest experiences that is, to represent oneself- whereby the speaker takes up a relation to something in the subjective world to which he has privileged access.

You are doing an excellent thing, one which will be wholesome for you, if, as you write me, you are persisting in your effort to attain sound understanding; it is foolish to pray for this when you can acquire it from yourself. We do not need to uplift our hands towards heaven, or to beg the keeper of a temple to let us approach his idol's ear, as if in this way our prayers were more likely to be heard. A god is near you, with you, and in you. This is what I mean, Lucilius: there sits a holy spirit within us, one who marks our good and bad deeds, and is our a guardian.

War has become the environment of our time if only because it is an accelerated form of innovation and education.

Thinking is an expedition into quietness.

Knowing that religion does not furnish grosser bigots than law, I expect little from old judges.

For the philosophy which is so important in each of us is not a technical matter; it is our more or less dumb sense of what life honestly and deeply means. It is only partly got from books; it is our individual way of just seeing and feeling the total push and pressure of the cosmos. ...I have heard friends and colleagues try to popularize philosophy... but they soon grew dry, and then technical, and the results were only partially encouraging. So my enterprise is a bold one. The founder of pragmatism... gave... lectures... with that very word in its title,-flashes of brilliant light relieved against Cimmerian darkness! None of us... understood all that he said-yet here I stand making a very similar venture. ...There is... a curious fascination in hearing deep things talked about, even though neither we nor the disputants understand them. We get the problematic thrill, we feel the presence of the vastness.

While people are engaged in creating a totally different world, they always form vivid images of the preceding world.

Alas, the Hero from of old has had to cramp himself into strange shapes: the world knows not well at any time what to do with him, so foreign is his aspect in the world!

We cannot stem linguistic change, but we can drag our feet. If each of us were to defy Alexander Pope and be the last to lay the old aside, it might not be a better world, but it would be a lovelier language.

As there is a use in medicine for poisons, so the world cannot move without rogues.

To be sure, risks abound; but no one is proposing compassionate stewardship of ecosystems by philosophers. Humans are capable of choosing our own future pain-sensitivity too; but any species-wide genomic shift in human pain tolerance will depend on the willingness of prospective parents to use preimplantation genetic screening.

Discovery depends upon the previous cultivation or natural clearness of the appropriate Idea, and therefore no discovery is the work of accident.

Boredom is a larval anxiety; depression, a dreamy hatred.
