Abstain from animals.

You must acquire the best knowledge first, and without delay; it is the height of madness to learn what you will later have to unlearn.

Unbelievers (so called) as well as of believers, there are many species, including almost every variety of moral type. But the best among them, as no one who has had opportunities of really knowing them will hesitate to affirm (believers rarely have that opportunity), are more genuinely religious, in the best sense of the word religion, than those who exclusively arrogate to themselves the title.

Tis very certain that each man carries in his eye the exact indication of his rank in the immense scale of men, and we are always learning to read it. A complete man should need no auxiliaries to his personal presence.

There are moments of sentimental and mystical experience. . . that carry an enormous sense of inner authority and illumination with them when they come. But they come seldom, and they do not come to everyone; and the rest of life makes either no connection with them, or tends to contradict them more than it confirms them. Some persons follow more the voice of the moment in these cases, some prefer to be guided by the average results. Hence the sad discordancy of so many of the spiritual judgments of human beings; a discordancy which will be brought home to us acutely enough before these lectures end.

Indulge in no wrathfulness, for a man when he indulges in wrath becomes then forgetful of his duty and good works . . . and sin and crime of every kind occur unto his mind, and until the subsiding of the wrath he is said to be just like Ahareman.

100 per cent of us die, and the percentage cannot be increased.

Fools learn wisdom through misfortune.

The art of progress is to preserve order amid change, and to preserve change amid order.

I cannot contribute anything to this world because I only have one method: agony.

Out from the heart of Nature rolled The burdens of the Bible old.

If I knew of something that could serve my nation but would ruin another, I would not propose it to my prince, for I am first a man and only then a Frenchman, because I am necessarily a man, and only accidentally am I French.

Nobody realizes that some people expend tremendous energy merely to be normal.

The practical consequence of such a[n individualistic] philosophy is the well-known democratic respect for the sacredness of individuality,-is, at any rate, the outward tolerance of whatever is not itself intolerant. These phrases are so familiar that they sound now rather dead in our ears. Once they had a passionate inner meaning. Such a passionate inner meaning they may easily acquire again if the pretension of our nation to inflict its own inner ideals and institutions vi et armis upon Orientals should meet with a resistance as obdurate as so far it has been gallant and spirited. Religiously and philosophically, our ancient national doctrine of live and let live may prove to have a far deeper meaning than our people now seem to imagine it to possess.

[B]ecause that which is finite is always bounded with reference to something... it is necessary that there should be no end... [N]umber also appears to be infinite, and mathematical magnitudes, and that which is beyond the heavens. And since that which is beyond is infinite, body also appears to be infinite, and it would seem that there are infinite worlds; for why is there rather void here than there? ...If also there is a vacuum, and an infinite place, it is necessary that there should be an infinite body: for in things which have a perpetual subsistence, capacity differs nothing from being. The speculation of the infinite is, however, attended with doubt: for many impossibilities happen both to those who do not admit that it has a subsistence, and to those who do. ...It is ...especially the province of a natural philosopher to consider if there be a sensible infinite magnitude.

The life of money-making is one undertaken under compulsion, and wealth is evidently not the good we are seeking; for it is merely useful and for the sake of something else.

Kant's philosophy shifts for the first time the whole of modern thought and being (Desein) into the clarity and transparency of the foundation (Begrundung). This determines every attitude toward knowledge since then, as well as the bounds (Abgrenzungen) and appraisals of the sciences in the nineteenth century up to the present time. Therein Kant towers so far above all who precede and follow that even those who reject him or go beyond him still remain entirely dependent upon him.

Plato has preserved in the Theaetetus - the story is that Thales, while occupied in studying the heavens above and looking up, fell into a well. A good-looking and whimsical maid from Thrace laughed at him and told him that while he might passionately want to know all things in the universe, the things in front of his very nose and feet were unseen by him." Plato added: "This jest also fits all those who become involved in Philosophy." Therefore, the question, What is a thing?" must always be rated as one that causes housemaids to laugh.

My atheism, like that of Spinoza, is true piety towards the universe and denies only gods fashioned by men in their own image, to be servants of their human interests.

Most Christians are superstitious rather than pious, and except for the name of Christ differ hardly at all from superstitious pagans.

One does not discover the absurd without being tempted to write a manual of happiness. "What! — by such narrow ways — ?" There is but one world, however. Happiness and the absurd are two sons of the same earth. They are inseparable. It would be a mistake to say that happiness necessarily springs from the absurd discovery. It happens as well that the feeling of the absurd springs from happiness.

He who establishes his argument by noise and command shows that his reason is weak.

The art of persuasion consists as much in that of pleasing as in that of convincing, so much more are men governed by caprice than by reason!

Every human being is the natural guardian of his own importance.

Each the herald is who wrote His rank, and quartered his own coat. There is no king nor sovereign state That can fix a hero's rate.

There is no such thing as data-driven thinking.

I have changed my mind about the testability and logical status of the theory of natural selection; and I am glad to have an opportunity to make a recantation.

The present contains nothing more than the past, and what is found in the effect was already in the cause.

Thus parents, by humouring and cockering them when little, corrupt the principles of nature in their children, and wonder afterwards to taste the bitter waters, when they themselves have poison'd the fountain.

I am extremely pleased by Daniel Fincke's article, which says exactly what I SHOULD have said and, to my regret, didn't make sufficiently clear in my Reason Rally speech. The best way to summarise it would be to modify the quotation from Johann Hari. Johann said, "I respect you too much to respect your ridiculous beliefs". From now on, my version will be, "I respect you too much to accept that you really believe anything so ridiculous as you claim. Please either defend those beliefs and explain why they are not ridiculous, or else declare that you do not hold them and publicly disown the church to which you claim loyalty."

In the dominant Western religious system, the love of God is essentially the same as the belief in God, in God's existence, God's justice, God's love. The love of God is essentially a thought experience. In the Eastern religions and in mysticism, the love of God is an intense feeling experience of oneness, inseparably linked with the expression of this love in every act of living.

There is no good father who would want to resemble our Heavenly Father.

The most important misunderstanding seems to me to lie in a confusion between the human necessities which I consider part of human nature, and the human necessities as they appear as drives, needs, passions, etc., in any given historical period. This division is not very different from Marx's concept of "human nature in general", to be distinguished from "human nature as modified in each historical period". The same distinction exists in Marx when he distinguishes between "constant" or "fixed" drives and "relative" drives. The constant drives "exist under all circumstances and ... can be changed by social conditions only as far as form and direction are concerned". The relative drives "owe their origin only to a certain type of social organization".

On doit exiger de moi que je cherche la vérité, mais non que je la trouve. One may demand of me that I should seek truth, but not that I should find it.

The single spirit doth simultaneously temper the whole together; this is the single soul of all things; all are filled with God.

There is but one law for all, namely, that law which governs all law, the law of our Creator, the law of humanity, justice, equity - the law of nature, and of nations.

Demonstrating is therefore only the means through which I strip my thought of the form of "mine-ness" so that the other person may recognize it as his own.

In Germany, the judicial system has been the whore of the German princes for centuries.

It is only the ignorant who despise education.

I have often regretted my speech, never my silence.

Despotism may govern without faith, but liberty cannot. How is it possible that society should escape destruction if the moral tie is not strengthened in proportion as the political tie is relaxed? And what can be done with a people who are their own masters if they are not submissive to the Deity?

Let thy mind rule thy tongue!

Have you learned the alphabet of heaven and can count three? Do you know the number of God's family? Can you put mysteries into words? Do you presume to fable of the ineffable? Pray, what geographer are you, that speak of heaven's topography? Whose friend are you that speak of God's personality? ... Tell me of the height of the mountains of the moon, or of the diameter of space, and I may believe you, but of the secret history of the Almighty, and I shall pronounce thee mad.

The characteristic of the hour is that the commonplace mind, knowing itself to be commonplace, has the assurance to proclaim the rights of the commonplace and to impose them wherever it will. As they say in the United States: "to be different is to be indecent." The mass crushes beneath it everything that is different, everything that is excellent, individual, qualified and select. Anybody who is not like everybody, who does not think like everybody, runs the risk of being eliminated. And it is clear, of course, that this "everybody" is not "everybody." "Everybody" was normally the complex unity of the mass and the divergent, specialised minorities. Nowadays, "everybody" is the mass alone.

Even the most wretched individual of our present society could not exist and develop without the cumulative social efforts of countless generations. Thus the individual, his freedom and reason, are the products of society, and not vice versa: society is not the product of individuals comprising it; and the higher, the more fully the individual is developed, the greater his freedom - and the more he is the product of society, the more does he receive from society and the greater his debt to it.

Let sanguine healthy-mindedness do its best with its strange power of living in the moment and ignoring and forgetting, still the evil background is really there to be thought of, and the skull will grin in at the banquet.

I believe that every human being with a physically normal brain can learn a great deal and can be surprisingly intellectual. I believe that what we badly need is social approval of learning and social rewards for learning.We can all be members of the intellectual elite and then, and only then, will a phrase like "America's right to know" and, indeed, any true concept of democracy, have any meaning.

Religious suffering is, at one and the same time, the expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people.The abolition of religion as the illusory happiness of the people is the demand for their real happiness. To call on them to give up their illusions about their condition is to call on them to give up a condition that requires illusions. The criticism of religion is, therefore, in embryo, the criticism of that vale of tears of which religion is the halo.Criticism has plucked the imaginary flowers on the chain not in order that man shall continue to bear that chain without fantasy or consolation, but so that he shall throw off the chain and pluck the living flower.
