Formerly, it was held by philosophers and mathematicians alike that the proofs in Geometry depended on the figure; nowadays, this is known to be false. In the best books there are no figures at all. The reasoning proceeds by the strict rules of formal logic from a set of axioms laid down to begin with.

Toleration is good for all, or it is good for none.

There's nothing nonsensical about saying that what would evolve if Darwinian selection has its head is something that you don't want to happen. And I could easily imagine trying to go against Darwinism.

I believe that the fundamental alternative for man is the choice between "life" and "death"; between creativity and destructive violence; between reality and illusions; between objectivity and intolerance; between brotherhood-independence and dominance-submission.

Every morning I shall concern myself anew about the boundary Between the love-deed-Yes and the power-deed-No And pressing forward honor reality. We cannot avoid Using power, Cannot escape the compulsion To afflict the world, So let us, cautious in diction And mighty in contradiction, Love powerfully.

I cannot imagine how the clockwork of the universe can exist without a clockmaker.

Bukharin, like Lenin, regarded the system of basing economic life on mass terror not as a transient necessity but as a permanent principle of socialist organization. He did not shrink from justifying all means of coercion and held, like Trotsky at the same period, that the new system called essentially for the militarization of labour - i.e. the use of police and military force to compel the whole population to work in such places and conditions as the state might arbitrarily decree. Indeed, once the market is abolished there is no longer any free sale of labour or competition between workers, and police coercion is therefore the only means of allocating "human resources". If hired labour is eliminated, only compulsory labour remains. In other words, socialism - as conceived by both Trotsky and Bukharin at this time - is a permanent, nation-wide labour camp.

Ever, as before, does Madness remain a mysterious-terrific, altogether infernal boiling-up of the Nether Chaotic Deep, through this fair-painted Vision of Creation, which swims thereon, which we name the Real.

Start with a planet like the earth, with a complement of simple compounds bound to exist upon it, add the energy of a nearby sun, and you are bound to end with nucleic acids. You can't avoid it.

The effects of opposition are wonderful. There are men who rise refreshed on hearing of a threat, - men to whom a crisis which intimidates and paralyzes the majority - demanding, not the faculties of prudence and thrift, but comprehension, immovableness, the readiness of sacrifice - comes graceful and beloved as a bride!

In a quarrel for earth, turn not to earth.

There is, however, a limit at which forbearance ceases to be a virtue.

When we have undermined the patriotic lie, we shall have cleared the path for that great structure wherein all nationalities shall be united into a universal brotherhood, - a truly FREE SOCIETY.

The plea of anger or of drunkenness - as having placed the criminal for the moment beyond the control of his reason - relieves him from the charge of premeditated and malicious intent; but a rational legislation will rather provide more severe than milder punishment for such cases, particularly if such a state of mind is habitual with the accused; for a single unlawful act may well constitute an exception from an otherwise blameless life. But a person who pleads, "I habitually get so angry or so drunk as not to be any longer master of my senses!" confesses thereby that he changes himself into a beast on a fixed principle, and that he is, therefore, not fit to live among rational beings.

To explain all nature is too difficult a task for any one man or even for any one age. 'Tis much better to do a little with certainty, & leave the rest for others that come after you, than to explain all things by conjecture without making sure of any thing.

Everyone is the other, and no one is himself. The they, which supplies the answer to the who of everyday Da-sein, is the nobody to whom every Da-sein has always already surrendered itself, in its being-among-one-another.

We shall, therefore, assume the complete physical equivalence of a gravitational field and a corresponding acceleration of the reference system.

Now to get back to our given Church: it lives almost entirely for modesty and moneyed piety. It zealously inveighs against the harm done to Joseph and the sheep, but it has made its arrangements with the upper classes and serves as their spiritual defender. It bristles at see-through blouses, but not at slums in which half-naked children starve, and not, above all, at the conditions that keep three quarters of mankind in misery. It condemns desperate girls who abort a foetus, but it consecrates war, which aborts millions. It has nationalized its God, nationalized him into ecclesiastic organization, and has inherited the Roman empire under the mask of the Crucified. It preserves misery and injustice, having first tolerated and then approved the class power that causes them; it prevents any seriousness about deliverance by postponing it to St. Never-Ever's Day or shifting it to the beyond.

I do not regard the late Carl Sagan as any kind of authority. On the contrary, as this book will show, I regard him in many ways as a dubious publicity seeker and careerist, more concerned to maintain his reputation as the brilliant and sceptical representative of hard-headed science than to look squarely and honestly at the facts.

I do not feel obliged to believe that the same God who has endowed us with senses, reason, and intellect has intended us to forgo their use and by some other means to give us knowledge which we can attain by them.

Satisfaction linked with dishonor or with harm to others is a prison for the seeker.

An intellectual is a person who has discovered something more interesting than sex.

Pour recueillir les biens inestimables qu'assure la liberté de la presse, il faut savoir se soumettre aux maux inévitables qu'elle fait naître. Translation: In order to enjoy the inestimable benefits that the liberty of the press ensures, it is necessary to submit to the inevitable evils it creates.

Life is an offensive, directed against the repetitious mechanism of the Universe.

The venerability, reliability, and utility of truth is something which a person demonstrates for himself from the contrast with the liar, whom no one trusts and everyone excludes. As a "rational" being, he now places his behavior under the control of abstractions. He will no longer tolerate being carried away by sudden impressions, by intuitions.

Every faculty in one man is the measure by which he judges of the like faculty in another. I judge of your sight by my sight, of your ear by my ear, of your reason by my reason, of your resentment by my resentment, of your love by my love. I neither have, nor can have, any other way of judging about them.

For the kingdom of heaven is with us today.

'BUT science and art! You are denying science and art: that is you are denying that by which humanity lives.' People constantly make this rejoinder to me, and they employ: this method in order to reject my arguments without examination. 'He rejects science and art, he wishes man to revert to a state of savagery - why listen to him or discuss with him?' But this is unjust. Not only do I not repudiate science, that is, the reasonable activity of humanity, and art - the expression of that reasonable activity - but it is just on behalf of that reasonable activity and its expression that I speak, only that It may be possible for mankind to escape from the savage state into which it is rapidly lapsing thanks to the false teaching of our time. It is only on that account that I speak as I do.

It is easy to romanticise, say, tigers or lions and cats. We admire their magnificent beauty, strength and agility. But we would regard their notional human counterparts as wanton psychopaths of the worst kind.

Lysander said, "Where the lion's skin will not reach, it must be pieced with the fox's."

I think they do it to pass the time, nothing more. But time is too large, it can't be filled up. Everything you plunge into it is stretched and disintegrates.

From a Darwinian point of view, human beliefs are adaptations to our part of the world. No doubt much of what we believe must be roughly accurate, or else we would not have survived. But the beliefs we have evolved might latch on to the world only enough to help us stumble our way through it, and then only for the time being. Human belief-systems could be useful illusions, appearing and disappearing as they prove to be more or less advantageous in the random walk of natural selection. Might not evolution be one of these illusions? Scientific naturalism is the theory that human beliefs are evolutionary adaptations whose survival has nothing to do with their truth. But in that case scientific naturalism is self-defeating, since on its own premises scientific theories cannot be known to be true.

Talk of mysteries! - Think of our life in nature, - daily to be shown matter, to come in contact with it, - rocks, trees, wind on our cheeks! The solid earth! the actual world! the common sense! Contact! Contact! Who are we? where are we?

Capitalist production does not exist at all without foreign commerce.

I am certainly interested in a tribunal in which, for having used my reason, I was deemed little less than a heretic. Who knows but men will reduce me from the profession of a philosopher to that of historian of the Inquisition! But they behave to me in order that I may become the ignoramus and the fool of Italy...

Man is a universe in little [Microcosm].

No epoch is homogeneous; whatever you may have assigned as the dominant note of a considerable period, it will always be possible to produce men, and great men, belonging to the same time, who exhibit themselves as antagonistic to the tone of their age.

Indeed, the drunken man while in that condition does not know the definition of drunkenness nor the scientific account of it; he has not the very least scientific knowledge of it. The sober man, on the other hand, knows the definition of drunkenness and its basis, yet he is not drunk in the very least. Again the doctor, when he is himself ill, knows the definition and causes of health and the remedies which restore it, and yet is lacking in health. Similarly there is a difference between knowing the true nature and causes and conditions of the ascetic life and actually leading such a life and forsaking the world.

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.

Delay is preferable to error.

Compassion for animals is intimately connected with goodness of character, and it may be confidently asserted that he, who is cruel to living creatures, cannot be a good man. Moreover, this compassion manifestly flows from the same source whence arise the virtues of justice and loving-kindness towards men.

Methinks I am like a man, who having struck on many shoals, and having narrowly escap'd shipwreck in passing a small frith, has yet the temerity to put out to sea in the same leaky weather-beaten vessel, and even carries his ambition so far as to think of compassing the globe under these disadvantageous circumstances.

Everybody knows that the same sum of money is of much greater value to a poor man that to a rich one. Give £10 a year to the man who has but £10 a year, you double his income, and you nearly double his enjoyments. Add £10 more, you do not add to his enjoyments so much as you did by the first £10. The third £10 is less valuable than the second, and the fourth less valuable than the third. To the possessor of £1,000 a year the addition of £10 would be scarcely perceptible; to the possessor of £10,000 it would not be worth slooping for.The richer a man is the less he is benefited by any further addition to his income. The man of £4,000 a year has four times the income of the man who has but £1,000; but does anybody suppose that he has four times the happiness?

Lifetime is a child at play, moving pieces in a game.

The Turks teach women that they have no souls, and are unworthy to enter paradise. The French would persuade them that they have no intellects, and are not made to engage in mental labors, and to tread the paths of art and science.

The right wing version really sees community represented either by... religion, or by nation, that these are units that... get dissolved under a liberal world order, through globalization, through the movement of people, goods, ideas and trade between nations, national identity becomes diluted and that sense of national community that held people together in democratic societies appears to be lost. ...Secularism ...is perceived as a loss by people that have religious faith. They believe that there is a form of militant secularism that is not allowing them to practice their religion, and for that reason a lot of religious conservatives in places like the United States, have turned against that liberal order.

I feel that these old Northmen wore looking into Nature with open eye and soul: most earnest, honest; childlike, and yet manlike; with a great-hearted simplicity and depth and freshness, in a true, loving, admiring, unfearing way.

Do not all theists insist that there can be no morality, no justice, honesty or fidelity without the belief in a Divine Power? Based upon fear and hope, such morality has always been a vile product, imbued partly with self-righteousness, partly with hypocrisy. As to truth, justice, and fidelity, who have been their brave exponents and daring proclaimers? Nearly always the godless ones: the Atheists; they lived, fought, and died for them. They knew that justice, truth, and fidelity are not conditioned in heaven, but that they are related to and interwoven with the tremendous changes going on in the social and material life of the human race; not fixed and eternal, but fluctuating, even as life itself.
