There is always something taboo, something repressed, unadmitted, or just glimpsed quickly out of the corner of one's eye because a direct look is too unsettling. Taboos lie within taboos, like the skin of an onion.

One may say "the eternal mystery of the world is its comprehensibility."

Mahomet was only fourteen; had no language but his own: much in Syria must have been a strange unintelligible whirlpool to him. But the eyes of the lad were open; glimpses of many things would doubtless be taken in, and lie very enigmatic as yet, which were to ripen in a strange way into views, into beliefs and insights one day. These journeys to Syria were probably the beginning of much to Mahomet. One other circumstance we must not forget: that he had no school-learning; of the thing we call school-learning none at all.

The administration of the great system of the universe, however, the care of the universal happiness of all rational and sensible beings, is the business of God and not of man. To man is allotted a much humbler department, but one much more suitable to the weakness of his powers, and to the narrowness of his comprehension; the care of his own happiness, of that of his family, his friends, his country: that he is occupied in contemplating the more sublime, can never be an excuse for his neglecting the more humble department.

But these young scholars who invade our hills, Bold as the engineer who fells the wood, And travelling often in the cut he makes, Love not the flower they pluck, and know it not, And all their botany is Latin names.

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

Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy. But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.

Some years ago, as Your Serene Highness well knows, I discovered in the heavens many things that had not been seen before our own age. The novelty of these things, as well as some consequences which followed from them in contradiction to the physical notions commonly held among academic philosophers, stirred up against me no small number of professors - as if I had placed these things in the sky with my own hands in order to upset nature and overturn the sciences. They seemed to forget that the increase of known truths stimulates the investigation, establishment, and growth of the arts; not their diminution or destruction.

Pyrrhus, when his friends congratulated to him his victory over the Romans under Fabricius, but with great slaughter of his own side, said to them, "Yes; but if we have such another victory, we are undone".

Now, moral philosophers generally prefer to talk about virtues, or about (specific) duties, rights, and so on, rather than about moral images of the world. There are obvious reasons for this; nevertheless, I think that it is a mistake, and that Kant is profoundly right. What we require in moral philosophy is, first and foremost, a moral image of the world, or rather--since, here again, I am more of a pluralist than Kant--a number of complementary moral images of the world.

The will is the living principle of the rational soul, is indeed itself reason, when purely and simply apprehended. That reason is itself active, means, that the pure will, as such, rules and is effectual. The infinite reason alone lies immediately and entirely in the purely spiritual order. The finite being lives necessarily at the same time in a sensuous order; that is to say, in one which presents to him other objects than those of pure reason; a material object, to be advanced by instruments and powers, standing indeed under the immediate command of the will, but whose efficacy is conditional also on its own natural laws.

When all these things are lacking there is no culture; there is in the strictest sense of the word, barbarism. And let us not deceive ourselves, this is what is beginning to appear in Europe under the progressive rebellion of the masses. The traveller who arrives in a barbarous country knows that in that territory there are no ruling principles to which it is possible to appeal. Properly speaking, there are no barbarian standards. Barbarism is the absence of standards to which appeal can be made.

To think we could have spared ourselves from living all that we have lived!

Acquire the contemplative way of seeing how all things change into one another, and constantly attend to it, and exercise thyself about this part [of philosophy]. For nothing is so much adapted to produce magnanimity. ...But as to what any man shall say or think about him, or do against him, he never even thinks of it, being himself contented with these two things: with acting justly in what he now does, and being satisfied with what is now assigned to him; and he lays aside all distracting and busy pursuits, and desires nothing else than to accomplish the straight course through the law, and by accomplishing the straight course to follow God.

Buying books would be a good thing if one could also buy the time to read them in: but as a rule the purchase of books is mistaken for the appropriation of their contents.

There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."

How close men, despite all their knowledge, usually live to madness? What is truth but to live for an idea? When all is said and done, everything is based on a postulate; but not until it no longer stands on the outside, not until one lives in it, does it cease to be a postulate.

Just as the witticism brings two very different real objects under one concept, the pun brings two different concepts, by the assistance of accident, under one word.

We have classical associations and great names of our own which we can confidently oppose to the most splendid of ancient times. Senate has not to our ears a sound so venerable as Parliament. We respect the Great Charter more than the laws of Solon. The Capitol and the Forum impress us with less awe than our own Westminster Hall and Westminster Abbey... The list of warriors and statesmen by whom our constitution was founded or preserved, from De Montfort down to Fox, may well stand a comparison with the Fasti of Rome. The dying thanksgiving of Sydney is as noble as the libation which Thrasea poured to Liberating Jove: and we think with far less pleasure of Cato tearing out his entrails than of Russell saying, as he turned away from his wife, that the bitterness of death was past.

Time, and Industry, produce everyday new knowledge.

Everywhere we remain unfree and chained to technology, whether we passionately affirm or deny it. But we are delivered over to it in the worst possible way when we regard it as something neutral; for this conception of it, to which today we particularly like to do homage, makes us utterly blind to the essence of technology.

This is the real secret of life-to be completely engaged with what you are doing in the here and now. And instead of calling it work, realize it is play.

The deepest thinking is humble. It is only concerned that the flame of truth which it keeps alive should burn with the strongest and purest heat; it does not trouble about the distance to which its brightness penetrates.

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

For the Lawes of Nature (as Justice, Equity, Modesty, Mercy, and (in summe)doing to others, as wee would be done to,) of themselves, without the terrour of some Power, to cause them to be observed, are contrary to our naturall Passions, that carry us to Partiality, Pride, Revenge, and the like. And Covenants, without the Sword, are but Words, and of no strength to secure a man at all.

Religious law makes it illegal for the ignorant to drink wine, but intelligence makes it legal for the intellectual.

I regard utility as the ultimate appeal on all ethical questions; but it must be utility in the largest sense, grounded on the permanent interests of man as a progressive being.

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

I hold in fact(1) That small portions of space are in fact of a nature analogous to little hills on a surface which is on the average flat; namely, that the ordinary laws of geometry are not valid in them.(2) That this property of being curved or distorted is continually being passed on from one portion of space to another after the manner of a wave.(3) That this variation of the curvature of space is what really happens in that phenomenon which we call the motion of matter, whether ponderable or etherial.(4) That in the physical world nothing else takes place but this variation, subject possibly to the law of continuity.

My immediate consciousness, my absolute perception, cannot go beyond myself, - I have immediate knowledge only of myself, whatever I know further I know only by reasoning, in the same manner in which I have come to those conclusions concerning the original powers of Nature, which certainly do not lie within the circle of my perceptions. I, however, - that which I call myself, - am not the man-forming power of Nature, but only one of its manifestations ; and only of this manifestation am I conscious, not of that power, whose existence I have only discovered from the necessity of explaining my own.

The repose of sleep refreshes only the body. It rarely sets the soul at rest. The repose of the night does not belong to us. It is not the possession of our being. Sleep opens within us an inn for phantoms. In the morning we must sweep out the shadows.

Beauty is merciless. You do not look at it, it looks at you and does not forgive.

Whether, then, all ought not immediately to discontinue and renounce it, with grief and abhorrence? Should not every society bear testimony against it, and account obstinate persisters in it bad men, enemies to their country, and exclude them from fellowship; as they often do for much lesser faults?

It was not until the ant and Veig had passed each other that Niall realized that he had been reading the ant's mind. It was a sensation like actually being the ant, as if he had momentarily taken possession of its body. And while he had been inside the ant's body, he had also become aware of all the other ants in the nest. It was a bewildering feeling, as if his mind had shattered into thousands of fragments, yet each fragment remained a coherent part of the whole.

Prussia had been the creation of a dynasty that had the nobility, the army and the higher bureaucracy for its backbone. The primary element was not the 'nation' or the Volk. Rather the state, more than the land or the ethnos, constituted the real foundation and unifying principle. There was none of that in Hitlerism.

To the existence of banks of discount for cash... there can be no objection, because there can be no danger of abuse, and they are a convenience both to merchants and individuals. I think they should even be encouraged, by allowing them a larger than legal interest on short discounts, and tapering thence, in proportion as the term of discount is lengthened, down to legal interest on those of a year or more. Even banks of deposit, where cash should be lodged, and a paper acknowledgment taken out as its representative, entitled to a return of the cash on demand, would be convenient for remittances, travelling persons, etc. But, liable as its cash would be to be pilfered and robbed, and its paper to be fraudulently re-issued, or issued without deposit, it would require skilful and strict regulation.

The mind must be indulged, and leisure must be given from time to time, which is the place of food and strength.

Free trade is not based on utility but on justice.

Magnanimity in politics is not seldom the truest wisdom; and a great empire and little minds go ill together.

If you wish to extinguish that enthusiasm, which inspires great thoughts, and impels to noble enterprises;-if you wish to render men's hearts cold, and unfeeling; and to substitute egotism in the room of generous, and ardent, patriotism,-if you wish to do this, only take away from the people their faith, and make them philosophers.

This is the ideal world, a perfect world of equality, fraternity, harmony, welfare, and justice.

The first among the sciences is that of statesmanship. That cannot be learnt in academies. No great minister, from Suger to Richelieu, ever occupied himself with physics or mathematics. The genius of the natural sciences makes impossible that other kind of genius, which is a talent unto itself.

Without an anti-environment, all environments are invisible.

What am I, other than a chance in the infinite probabilities of not having been!

The journey of a thousand miles begins with a single step.

Our preaching does not stop with the law. That would lead to wounding without binding up, striking down and not healing, killing and not making alive, driving down to hell and not bringing back up, humbling and not exalting. Therefore, we must also preach grace and the promise of forgiveness - this is the means by which faith is awakened and properly taught. Without this word of grace, the law, contrition, penitence, and everything else are done and taught in vain.

Imagination places the future world for us either above or below or in reincarnation. We dream of travels throughout the universe: is not the universe within us? We do not know the depths of our spirit. The mysterious path leads within. In us, or nowhere, lies eternity with its worlds, the past and the future. Fragment No. 16 Variant translations: We dream of a journey through the universe. But is the universe then not in us? We do not know the depths of our spirit. Inward goes the secret path. Eternity with its worlds, the past and the future, is in us or nowhere.
