Much learning does not teach understanding.

A man builds a fine house; and now he has a master, and a task for life: he is to furnish, watch, show it, and keep it in repair, the rest of his days.

By far my greatest dread in life [...] is that (some variant of) the Everett interpretation of Quantum Mechanics is true. Dave's Diary, BLTC Research, May 1996

The Methods of Observation of Quantity in general, are 'Numeration', which is precise by the nature of Number; the 'Measurement of Space' and 'of Time', which are easily made precise; the 'Conversion of Space and Time', by which each aids the measurement of the other. The Idea of Space becomes more clear by studying 'Geometry'; the Idea of Force, by studying 'Mechanics'; the Ideas of Likeness, of Kind, of subordination of Classes, by studying 'Natural History'.

The dullness of fact is the mother of fiction.

Society ... can afford to grant more than before because its interests have become the innermost drives of its citizens.

To some extent, mythology is only the most ancient history and biography. So far from being false or fabulous in the common sense, it contains only enduring and essential truth, the I and you, the here and there, the now and then, being omitted. Either time or rare wisdom writes it. Before printing was discovered, a century was equal to a thousand years. The poet is he who can write some pure mythology to-day without the aid of posterity.

The wraith of Sigmund said. "You know what this is, I suppose. Religious melancholia. Stop while there is time. If you dive, you dive into insanity."

May we not say, perhaps, that the evil man is annihilated because he wished to be annihilated, or that he did not wish strongly enough to eternalize himself because he was evil? May we say that it is not believing in the other life which causes a man to be good, but rather that being good causes him believe in it? And what is being good and being evil? These states belong to the sphere of ethics, not of religion; or rather, does not the doing good though being evil pertain to ethics, and the being good [forgivable] though doing evil, to religion?

You take souls for vegetables.... The gardener can decide what will become of his carrots but no one can choose the good of others for them.

Theology recognizes the contingency of human existence only to derive it from a necessary being, that is, to remove it. Theology makes use of philosophical wonder only for the purpose of motivating an affirmation which ends it. Philosophy, on the other hand, arouses us to what is problematic in our own existence and in that of the world, to such a point that we shall never be cured of searching for a solution.

Creatures extremely low in the intellectual scale may have conception. All that is required is that they should recognize the same experience again. A polyp would be a conceptual thinker if a feeling of 'Hello! thingumbob again!' ever flitted through its mind.

When the empirical investigator glories in his refusal to go beyond the specialized observation dictated by the traditions of his discipline, be they ever so inclusive, he is making a virtue out of a defense mechanism which insures him against questioning his presuppositions.

A philosopher who is not taking part in discussions is like a boxer who never goes into the ring.

Happy is the one in whom there is true sorrow over his sin, so that the extreme unimportance to him of everything else is only the negative expression of the confirmation that one thing is unconditionally important to him, so that the unconditional unimportance to him of everything else is a deadly sickness that still is very far from being a sickness unto death but is precisely unto life, because the life is in this, that one thing is unconditionally important to him: to find forgiveness.

The universe is composed of matter, and, as a system, is sustained by motion. Motion is not a property of matter, and without this motion the solar system could not exist. Were motion a property of matter, that undiscovered and undiscoverable thing, called perpetual motion, would establish itself. It is because motion is not a property of matter, that perpetual motion is an impossibility in the hand of every being, but that of the Creator of motion. When the pretenders to Atheism can produce perpetual motion, and not till then, they may expect to be credited.

Would not all we mean by "communication between mind and mind" be provided for if we suppose that common knowledge comes about, not from our explaining things to one another, but from things explaining themselves in the same terms to us all? Accepting the object as its own interpreter, as its own "medium of communication," do we not begin to understand what is utterly dark on any other view, how it comes to pass that the resulting knowledge is a common possession?

As soon as the soul has been made to perceive that a thing can conduct it to that which it loves supremely, it must inevitably embrace it with joy.

Philosophy ... must not bargain away anything of the emphatic concept of truth.

I cannot sufficiently admire the eminence of those men's wits, that have received and held it to be true, and with the sprightliness of their judgments offered such violence to their own senses, as that they have been able to prefer that which their reason dictated to them, to that which sensible experiments represented most manifestly to the contrary. ...I cannot find any bounds for my admiration, how that reason was able in Aristarchus and Copernicus, to commit such a rape on their senses, as in despite thereof to make herself mistress of their credulity.

Those who claim to care about the wellbeing of human beings and the preservation of our environment should become vegetarians for that reason alone. They would thereby increase the amount of grain available to feed people elsewhere, reduce pollution, save water and energy, and cease contributing to the clearing of forests; moreover, since a vegetarian diet is cheaper than one based on meat dishes, they would have more money available to devote to famine relief, population control, or whatever social or political cause they thought most urgent. ... when nonvegetarians say that "human problems come first" I cannot help wondering what exactly it is that they are doing for human beings that compels them to continue to support the wasteful, ruthless exploitation of farm animals.

Can the man say, Fiat lux, Let there be light; and out of chaos make a world? Precisely as there is light in himself, will he accomplish this.

The modern proletarian class doesn't carry out its struggle according to a plan set out in some book or theory; the modern workers' struggle is a part of history, a part of social progress, and in the middle of history, in the middle of progress, in the middle of the fight, we learn how we must fight... That's exactly what is laudable about it, that's exactly why this colossal piece of culture, within the modern workers' movement, is epoch-defining: that the great masses of the working people first forge from their own consciousness, from their own belief, and even from their own understanding the weapons of their own liberation.

One often makes a remark and only later sees how true it is.

Man is free at the instant he wants to be.

Any ethics that needs religion is bad ethics, and any religion that tries to do so is bad religion. Of course, there are plenty of both around.

I'm not a Baptist in any formal way. I go to the Baptist church, where my wife plays the piano, on days of bad weather. On days of good weather, I ramble off into the woods somewhere. I am a person who takes the Gospel seriously, but I have had trouble conforming my thoughts to a denomination.

If there is a devil in human history, that devil is the principle of command. It alone, sustained by the ignorance and stupidity of the masses, without which it could not exist, is the source of all the catastrophes, all the crimes, and all the infamies of history.

Justice was in all countries originally administered by the priesthood; nor indeed could laws in their first feeble state have either authority or sanction, so as to compel men to relinquish their natural independence, had they not appeared to come down to them enforced by beings of more than human power. The first openings of civility have been everywhere made by religion. Amongst the Romans, the custody and interpretation of the laws continued solely in the college of the pontiffs for above a century.

Those least responsible for climate change are worst affected by it.

The aim of philosophy is to erect a wall at the point where language stops anyway.

Little can be hoped for from a ruler... who has not at some time or other been preoccupied, even if only confusedly, with the first beginning and ultimate end of all things, and above all of man, with the "why" of his origin and the "wherefore" of his destiny.

If you tried to doubt everything you would not get as far as doubting anything. The game of doubting itself presupposes certainty.

In organized groups such as the army or the Church there is either no mention of love whatsoever between the members, or it is expressed only in a sublimated and indirect way, through the mediation of some religious imagine in the love of whom the members unite and whose all-embracing love they are supposed to imitate in their attitude towards each other. ... It is one of the basic tenets of fascist leadership to keep primary libidinal energy on an unconscious level so as to divert its manifestations in a way suitable to political ends.

One grasps incomparably more things in boredom than by labor, effort being the mortal enemy of meditation.

My mission is to suffer for all those who suffer without knowing it. I must pay for them, expiate their unconsciousness, their luck to be ignorant of how unhappy they are.

A new word is like a fresh seed sown on the ground of the discussion.

The general nature of the speech act fallacy can be stated as follows, using "good" as our example. Calling something good is characteristically praising or commending or recommending it, etc. But it is a fallacy to infer from this that the meaning of "good" is explained by saying it is used to perform the act of commendation.

Whoever does not philosophize for the sake of philosophy, but rather uses philosophy as a means, is a sophist.

"Do I look like someone who has something to do here on Earth?" - That's what I'd like to answer the busybodies who inquire into my activities.

To believe in a God means to understand the question about the meaning of life. To believe in a God means to see that the facts of the world are not the end of the matter. To believe in God means to see that life has a meaning.
