Ether is, in effect, a merely hypothetical entity, valuable only in so far as it explains that which by means of it we endeavor to explain - light, electricity, or universal gravitation - and only so far as these facts cannot be explained in any other way. In like manner the idea of God is also an hypothesis, valuable only in so far as it enables us to explain that which by means of it we endeavor to explain - the essence and existence of the Universe - and only so long as these cannot be explained in any other way. And since in reality we explain the Universe neither better nor worse with this idea than without it, the idea of God, the supreme petitio principii, is valueless.

But if the labourers could live on air they could not be bought at any price.

Fashion is the science of appearances, and it inspires one with the desire to seem rather than to be.

The important thing is not the planning of an Index Verborum Prohibitorum of current noble nouns, but rather the examination of their linguistic function.

To become god is merely to be free on this earth, not to serve an immortal being.

The spirit of Poesy is the morning light, which makes the Statue of Memnon sound.

Is it not the interest of the human race, that every one should be so taught and placed, that he would find his highest enjoyment to arise from the continued practice of doing all in his power to promote the well-being, and happiness, of every man, woman, and child, without regard to their class, sect, party, country or colour?

Faith, like light, should ever be simple and unbending; while love, like warmth, should beam forth on every side, and bend to every necessity of our brethren.

The more exquisite any good is, of which a small specimen is afforded us, the sharper is the evil, allied to it; and few exceptions are found to this uniform law of nature. The most sprightly wit borders on madness; the highest effusions of joy produce the deepest melancholy; the most ravishing pleasures are attended with the most cruel lassitude and disgust; the most flattering hopes make way for the severest disappointments. And, in general, no course of life has such safety (for happiness is not to be dreamed of) as the temperate and moderate, which maintains, as far as possible, a mediocrity, and a kind of insensibility, in every thing. As the good, the great, the sublime, the ravishing are found eminently in the genuine principles of theism; it may be expected, from the analogy of nature, that the base, the absurd, the mean, the terrifying will be equally discovered in religious fictions and chimeras.

His master was angry, and delivered him to the torturers until he should pay all that was due to him. "So My heavenly Father also will do to you if each of you, from his heart, does not forgive his brother his trespasses."

The modern world gives proof at every point that it is far easier to destroy institutions than to create them. Nevertheless, few people seem to understand this truth.

The greatest states have been overthrown by the young and sustained and restored by the old. ... Rashness is the product of the budding-time of youth, prudence of the harvest-time of age.

Were I to pray for a taste which should stand me in stead under every variety of circumstances, and be a source of happiness and cheerfulness to me during life, and a shield against its ills, however things might go amiss and the world frown upon me, it would be a taste for reading... Give a man this taste, and the means of gratifying it, and you can hardly fail of making him a happy man; unless, indeed, you put into his hands a most perverse selection of books. You place him in contact with the best society in every period of history,-with the wisest, the wittiest, the tenderest, the bravest, and the purest characters who have adorned humanity. You make him a denizen of all nations, a contemporary of all ages. The world has been created for him.

It is a palpable falsehood to say we can have specie for our paper whenever demanded. Instead, then, of yielding to the cries of scarcity of medium set up by speculators, projectors and commercial gamblers, no endeavors should be spared to begin the work of reducing it by such gradual means as may give time to private fortunes to preserve their poise, and settle down with the subsiding medium; and that, for this purpose, the States should be urged to concede to the General Government, with a saving of chartered rights, the exclusive power of establishing banks of discount for paper.

Love, a tacit agreement between two unhappy parties to overestimate each other. p. 111, first American edition

And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me. For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence.

I would rather be a devil in alliance with truth, than an angel in alliance with falsehood.

All hopes and despairs vanish in the voracious, funneling whirlwind of God. God laughs, wails, kills, sets us on fire, and then leaves us in the middle of the way, charred embers. And I rejoice to feel between my temples, in the flicker of an eyelid, the beginning and the end of the world. I condense into a lightning moment the seeding, sprouting, blossoming, fructifying, and the disappearance of every tree, animal, man, star, and god. All Earth is a seed planted in the coils of my mind. Whatever struggles for numberless years to unfold and fructify in the dark womb of matter bursts in my head like a small and silent lightning flash. Ah! let us gaze intently on this lightning flash, let us hold it for a moment, let us arrange it into human speech. Let us transfix this momentary eternity which encloses everything, past and future, but without losing in the immobility of language any of its gigantic erotic whirling.

No more useful inquiry can be proposed than that which seeks to determine the nature and the scope of human knowledge. ... This investigation should be undertaken once at least in his life by anyone who has the slightest regard for truth, since in pursuing it the true instruments of knowledge and the whole method of inquiry come to light. But nothing seems to me more futile than the conduct of those who boldly dispute about the secrets of nature ... without yet having ever asked even whether human reason is adequate to the solution of these problems.

The whole conception of God is a conception derived from the ancient Oriental despotisms. It is a conception quite unworthy of free men. When you hear people in church debasing themselves and saying that they are miserable sinners, and all the rest of it, it seems contemptible and not worthy of self-respecting human beings. We ought to stand up and look the world frankly in the face. We ought to make the best we can of the world, and if it is not so good as we wish, after all it will still be better than what these others have made of it in all these ages. A good world needs knowledge, kindliness, and courage; it does not need a regretful hankering after the past, or a fettering of the free intelligence by the words uttered long ago by ignorant men.

Feeling does not succeed in converting consolation into truth, nor does reason succeed in converting truth into consolation.

The belief in unity that has fuelled so many utopian dreams is an effort to reconcile the irreconcilable that ends in repression. Berlin suggests we renounce this venerable faith, and learn how to live with intractable conflict.

Everyone explains that discussions about Socialism are exceedingly obscure; this obscurity is due, to a large extent, to the fact that contemporary socialists use a terminology which no longer corresponds to their ideas.

Rest satisfied with doing well, and leave others to talk of you as they please.

Again, defenders of utility often find themselves called upon to reply to such objections as this-that there is not time, previous to action, for calculating and weighing the effects of any line of conduct on the general happiness. This is exactly as if any one were to say that it is impossible to guide our conduct by Christianity, because there is not time, on every occasion on which anything has to be done, to read through the Old and New Testaments. The answer to the objection is, that there has been ample time, namely, the whole past duration of the human species. During all that time mankind have been learning by experience the tendencies of actions.

The God of the Christians is a father who makes much of his apples, and very little of his children.

Fine manners need the support of fine manners in others.

The conformation of his mind was such that whatever was little seemed to him great, and whatever was great seemed to him little. Serious business was a trifle to him, and trifles were his serious business.

I assert once again as a truth to which history as a whole bears witness that men may second their fortune, but cannot oppose it; that they may weave its warp, but cannot break it. Yet they should never give up, because there is always hope, though they know not the end and more towards it along roads which cross one another and as yet are unexplored; and since there is hope, they should not despair, no matter what fortune brings or in what travail they find themselves.

Try to learn something about everything and everything about something.

Those who are not shocked when they first come across quantum theory cannot possibly have understood it.

Of our desires some are natural and necessary, others are natural but not necessary; and others are neither natural nor necessary, but are due to groundless opinion.

The spiritual men of India, a great and watchful multitude whose spiritual status is unattainable, are many of them catholics in a deeper sense than we of the West have yet given to the word ....

God ... desires His creature to be able to oppose Him. He has given that creature freedom. ... When man turns away from evil with that whole measure of power with which he is able to rebel against God, then he has truly turned to God.

If throughout your life you abstain from murder, theft, fornication, perjury, blasphemy, and disrespect toward your parents, your church, and your king, you are conventionally held to deserve moral admiration even if you have never done a single kind or generous or useful action. This very inadequate notion of virtue is an outcome of taboo morality, and has done untold harm.

The radical empiricist onslaught ... provides the methodological justification for the debunking of the mind by the intellectuals-a positivism which, in its denial of the transcending elements of Reason, forms the academic counterpart of the socially required behavior.

This makes me think that the French Revolution is a great epoch and that its consequences, in all kinds of ways, will be felt far beyond the time of its explosion and the limits of its birthplace.

Consider, for example, the state of Science generally, in Europe, at this period. It is admitted, on all sides, that the Metaphysical and Moral Sciences are falling into decay, while the Physical are engrossing, every day, more respect and attention. In most of the European nations there is now no such thing as a Science of Mind; only more or less advancement in the general science, or the special sciences, of matter.

Faith feels itself secure neither with universal consent, nor with tradition, nor with authority. It seeks support of its enemy, reason.

Or indeed we may say again, it is in what I called Portrait-painting, delineating of men and things, especially of men, that Shakspeare is great. All the greatness of the man comes out decisively here. It is unexampled, I think, that calm creative perspicacity of Shakspeare. The thing he looks at reveals not this or that face of it, but its inmost heart and generic secret: it dissolves itself as in light before him, so that he discerns the perfect structure of it. Creative, we said: poetic creation, what is this too but seeing the thing sufficiently? The word that will describe the thing, follows of itself from such clear intense sight of the thing. And is not Shakspeare's morality, his valour, candour, tolerance, truthfulness; his whole victorious strength and greatness, which can triumph over such obstructions, visible there too? Great as the world!

It would be too ridiculous to go about seriously to prove that wealth does not consist in money, or in gold and silver; but in what money purchases, and is valuable only for purchasing. Money no doubt, makes always a part of the national capital; but it has already been shown that it generally makes but a small part, and always the most unprofitable part of it.

All the measures now proposed are only a compromise with the errors of the present systems; but as these errors now almost universally exist, and must be overcome solely by the force of reason; and as reason, to effect the most beneficial purposes, makes her advance by slow degrees, and progressively substantiates one truth of high import after another, it will be evident, to minds of comprehensive and accurate thought, that by these and similar compromises alone can success be rationally expected in practice. For such compromises bring truth and error before the public; and whenever they are fairly exhibited together, truth must ultimately prevail.

Everything I have written in these lectures underlines the importance to the intellectual of passionate engagement, risk, exposure, commitment to principles, vulnerability in debating and being involved in worldly causes. For example, the difference I drew earlier between a professional and an amateur intellectual rests precisely on this, that the professional claims detachment on the basis of a profession and pretends to objectivity, whereas the amateur is moved neither by reward nor by the fulfillment of an immediate career plan but by a committed engagement with ideas and values in the public sphere.

Seeing only what is fair, Sipping only what is sweet, Thou dost mock at fate and care.
