I was sitting in a chair in the patent office at Bern when all of sudden a thought occurred to me: If a person falls freely he will not feel his own weight. I was startled. This simple thought made a deep impression on me. It impelled me toward a theory of gravitation.

Shakespeare's fault is not the greatest into which a poet may fall. It merely indicates a deficiency of taste.

What one has to say to begin with is that, as humans, we are limited in intelligence and we really have no reliable foresight. So none of us will come up with answers to the whole great problem. What we can do is judge our behavior, our history, and our present situation by a better standard than "efficiency" or "profit," or those measures that we're still using to determine economic decisions.

It's not the experience that happens to you: it's what you do with the experience that happens to you.

The message of radio is one of violent, unified implosion and resonance.

The World and Life are one. Physiological life is of course not "Life". And neither is psychological life. Life is the world. Ethics does not treat of the world. Ethics must be a condition of the world, like logic. Ethics and Aesthetics are one.

Without an understanding of causality there can be no theory of communication. What passes as information theory today is not communication at all, but merely transportation.

God may forgive sins, he said, but awkwardness has no forgiveness in heaven or earth.

We are so captivated by and entangled in our subjective consciousness that we have forgotten the age-old fact that God speaks chiefly through dreams and visions.

If an event really happened which was not a part of the uniformity of nature, it would have two properties: no evidence could give the right to believe it to any except those whose actual experience it was; and no inference worthy of belief could be founded upon it at all. Are we then bound to believe that nature is absolutely and universally uniform? Certainly not; we have no right to believe anything of this kind. The rule only tells us that in forming beliefs which go beyond our experience, we may make the assumption that nature is practically uniform so far as we are concerned. Within the range of human action and verification, we may form, by help of this assumption, actual beliefs; beyond it, only those hypotheses which serve for the more accurate asking of questions.

It is enough to ask somebody for his weapons without saying 'I want to kill you with them', because when you have his weapons in hand, you can satisfy your desire.

It is not by prayer and humility that you cause things to go as you wish, but by acquiring a knowledge of natural laws.

Organizations and institutions permit stable expectations to be formed by each member of the group as to the behavior of the other members under specified conditions.

We should say: 'Causes almost identical take almost the same time to produce almost the same effects.'

And so I am not concerned to justify the perpetrators of violence but to enquire into the function of the violence of the working classes in contemporary socialism.

Self-command is the main elegance.

In all European countries, especially in England, one class of Captains and commanders of men, recognizable as the beginning of a new real and not imaginary "Aristocracy," has already in some measure developed itself: the Captains of Industry;-happily the class who above all, or at least first of all, are wanted in this time. In the doing of material work, we have already men among us that can command bodies of men. And surely, on the other hand, there is no lack of men needing to be commanded: the sad class of brother-men whom we had to describe as "Hodge's emancipated horses," reduced to roving famine,-this too has in all countries developed itself; and, in fatal geometrical progression, is ever more developing itself, with a rapidity which alarms every one. On this ground, if not on all manner of other grounds, it may be truly said, the "Organization of Labor" (not organizable by the mad methods tried hitherto) is the universal vital Problem of the world.

If a false thought is so much as expressed boldly and clearly, a great deal has already been gained.

Morality must be the heart of our existence, if it is to be what it wants to be for us. ... The highest form of philosophy is ethics. Thus all philosophy begins with "I am." The highest statement of cognition must be an expression of that fact which is the means and ground for all cognition, namely, the goal of the I.

The universe is the bible of a true Theophilanthropist. It is there that he reads of God. It is there that the proofs of his existence are to be sought and to be found. As to written or printed books, by whatever name they are called, they are the works of man's hands, and carry no evidence in themselves that God is the author of any of them. It must be in something that man could not make, that we must seek evidence for our belief, and that something is the universe; the true bible; the inimitable word, of God.

Money, as a matter of principle, makes everything the same.

The true function of logic ... as applied to matters of experience ... is analytic rather than constructive; taken a priori, it shows the possibility of hitherto unsuspected alternatives more often than the impossibility of alternatives which seemed prima facie possible. Thus, while it liberates imagination as to what the world may be, it refuses to legislate as to what the world is.

I would take to be quite a fool any man who would make a book full of laws and statutes for an apple tree telling it how to bear apples and not thorns, when the tree is able by its own nature to do this better than the man with all his books can describe and demand.

When I was a child, the institution of war, which, by then, had been in existence for perhaps about five thousand years, was still being taken for granted by most people in the World as a normal and acceptable fact of life. One small religious community, the Society of Friends, was at that time singular in condemning war as immoral and in consequently refusing to have any part or lot in war-making.

If any one hearken with understanding to these sayings of mine many a deed worthy of a good man shall he perform and many a foolish deed be spared.

In the field of philosophy Kant was the first to take the next decisive step towards the point of view that not only the qualities revealed by the senses, but also space and spatial characteristics have no objective significance in the absolute sense; in other words, that space, too, is only a form of our perception.

But there is nothing sweeter than to dwell in towers that rise On high, serene and fortified with teachings of the wise, From which you may peer down upon the others as they stray This way and that, seeking the path of life, losing their way: The skirmishing of wits, the scramble for renown, the fight, Each striving harder than the next, and struggling day and night, To climb atop a heap of riches and lay claim to might.

I have often thought that nothing would do more extensive good at small expense than the establishment of a small circulating library in every county, to consist of a few well-chosen books, to be lent to the people of the country under regulations as would secure their safe return in due time.

To make an end of all things on Earth, and our Planetical System of the World, he (God) need but put out the Sun.

Care and responsibility are constituent elements of love, but without respect for and knowledge of the beloved person, love deteriorates into domination and possessiveness. Respect is not fear and awe; it denotes, in accordance with the root of the word (respicere = to look at), the ability to see a person as he is, to be aware of his individuality and uniqueness. To respect a person is not possible without knowing him; care and responsibility would be blind if they were not guided by the knowledge of the person's individuality.

Sexual activity is driven by the same aims and motives as reading poetry or listening to music: to escape the limitations imposed by the need for particularity in the consciousness.

Seeing therefore they are both [heat and pain] immediately perceived at the same time, and the fire affects you only with one simple, or uncompounded idea, it follows that this same simple idea is both the intense heat immediately perceived, and the pain; and consequently, that the intense heat immediately perceived, is nothing distinct from a particular sort of pain.

The end of man (as a factual anthropological limit) is announced to thought from the vantage of the end of man (as a determined opening or the infinity of a telos). Man is that which is in relation to his end, in the fundamentally equivocal sense of the word. Since always.

Do nothing, only keep agitating, debating; and things will destroy themselves.

Self-alienation is the source of all degradation as well as, on the contrary, the basis of all true elevation. The first step will be a look inward, an isolating contemplation of our self. Whoever remains standing here proceeds only halfway. The second step must be an active look outward, an autonomous, determined observation of the outer world. Fragment No. 24 Variant translation: The first step is to look within, the discriminating contemplation of the self. He who remains at this point only half develops. The second step must be a telling look without, independent, sustained contemplation of the external world.

The invention of printing did away with anonymity, fostering ideas of literary fame and the habit of considering intellectual effort as private property.

A gun gives you the body, not the bird.

Properly speaking, the Land belongs to these two: To the Almighty God; and to all His Children of Men that have ever worked well on it, or that shall ever work well on it. No generation of men can or could, with never such solemnity and effort, sell Land on any other principle: it is not the property of any generation, we say, but that of all the past generations that have worked on it, and of all the future ones that shall work on it.

All morning, I did nothing but repeat: "Man is an abyss, man is an abyss." - I could not, alas, find anything better.

Unlimited exploitation of cheap labour-power is the sole foundation of their power to compete.

Few men have been admired by their own domestics.

A subject interests me and holds my attention only so long as it presents me with difficulties, only so long as I am at odds with it and have, as it were, to struggle with it; but once I have mastered it I hurry on to something else, to a new subject; for my interest is not confined to any particular field or subject; it extends to everything human. This does not mean that I am an intellectual miser or egoist, who amasses knowledge for himself alone; by no means! What I do and think for myself, I must also think and do for others. But I feel the need of instructing others in a subject only so long as, while instructing others, I am also instructing myself.

Indeed it may be only by risking the incoherence of identity that connection is possible.

A person who wakes up after a night of unbroken sleep has the illusion of beginning something new. When one instead remains awake the whole night long, nothing new begins.

Being good is just a matter of temperament in the end.

Money is miraculous. What miraculous facilities has it yielded, will it yield us; but also what never-imagined confusions, obscurations has it brought in; down almost to total extinction of the moral-sense in large masses of mankind!

Colonization on a grand scale is a political necessity of absolutely the first order. A nation that does not colonize is irrevocably vowed to socialism, to war between rich and poor. The conquest of a nation of inferior race by a superior race, which establishes itself as the ruler, has nothing shocking about it.

The principles of ethics come from our own nature as social, reasoning beings.

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.
