Of all the cultural aspects of humanity, the only one which is not broken up into national or regional splinters is science. Different nations have different languages, they may have different religions, may have different dietaries, may have different holidays, different ways of thinking, but here's only one science. 

It really comes down to parsimony, economy of explanation. It is possible that your car engine is driven by psychokinetic energy, but if it looks like a petrol engine, smells like a petrol engine and performs exactly as well as a petrol engine, the sensible working hypothesis is that it is a petrol engine.

Fathers and teachers, I ponder, "What is hell?" I maintain that it is the suffering of being unable to love.

You do not ask what is the value, or what is the use, of this feeling. Of what use is the universe? What is the practical application of a million galaxies? Yet just because it has no use, it has a use-which may sound like a paradox, but is not. What, for instance, is the use of playing music? If you play to make money, to outdo some other artist, to be a person of culture, or to improve your mind, you are not really playing-for your mind is not on the music. You don't swing. When you come to think of it, playing or listening to music is a pure luxury, an addiction, a waste of valuable time and money for nothing more than making elaborate patterns of sound.

They also gave it the title of "opinion," because truth and falsity lie in opinion. And they called it "movement," "generation," "change," "division," "length," "multiplication," "addition," "kinship," "relativity," "the ratio in proportionality." For the relation of two numbers is of every conceivable form.

An army and navy represents the people's toys.

The "tragic flaw" is not a detail of characterization, a mere "fly in the ointment", but a structural feature of ordinary consciousness.

A scientist worthy of the name, above all a mathematician, experiences in his work the same impression as an artist; his pleasure is as great and of the same nature. ...we work not only to obtain the positive results which, according to the profane, constitute our one and only affection, as to experience this esthetic emotion and to convey it to others who are capable of experiencing it.

The whole plan of our order should be based on the idea of preparing men of firmness and virtue bound together by unity of conviction-aiming at the punishment of vice and folly, and patronizing talent and virtue: raising worthy men from the dust and attaching them to our Brotherhood. Only then will our order have the power unobtrusively to bind the hands of the protectors of disorder and to control them without their being aware of it. In a word, we must found a form of government holding universal sway, which should be diffused over the whole world without destroying the bonds of citizenship, and beside which all other governments can continue in their customary course and do everything except what impedes the great aim of our order, which is to obtain for virtue the victory over vice.

Christianity is at the very root of the evil that has corrupted the West. This is the truth, and it admits no doubt.

God's love for us is not the reason for which we should love him. God's love for us is the reason for us to love ourselves.

The veneration of Mary is inscribed in the very depths of the human heart.

The arbitrary rule of a just and enlightened prince is always bad. His virtues are the most dangerous and the surest form of seduction: they lull a people imperceptibly into the habit of loving, respecting, and serving his successor, whoever that successor may be, no matter how wicked or stupid.

Reading after a certain age diverts the mind too much from its creative pursuits. Any man who reads too much and uses his own brain too little falls into lazy habits of thinking, just as the man who spends too much time in the theater is tempted to be content with living vicariously instead of living his own life.

For man seeketh in society comfort, use, and protection: and they be three wisdoms of divers natures, which do often sever: wisdom of the behaviour, wisdom of business, and wisdom of state.

There are two threats to reason, the opinion that one knows the truth about the most important things and the opinion that there is no truth about them. Both of these opinions are fatal to philosophy; the first asserts that the quest for truth is unnecessary, while the second asserts that it is impossible. The Socratic knowledge of ignorance, which I take to be the beginning point of all philosophy, defines the sensible middle ground between two extremes.

You must go to Mahometanism, to Buddhism, to the East, to the Sufis & Fakirs, to Pantheism, for the right growth of mysticism.

There has been a general trend in recent times toward a Unitarian mythology and the worship of one God. This is the tendency which it is customary to regard as spiritual progress. On what grounds? Chiefly, so far as one can see, because we in the Twentieth Century West are officially the worshippers of a single divinity. A movement whose consummation is Us must be progressive. Quod erat demonstrandum.

Labour not after riches first, and think thou afterwards wilt enjoy them. He who neglecteth the present moment, throweth away all that he hath. As the arrow passeth through the heart, while the warrior knew not that it was coming; so shall his life be taken away before he knoweth that he hath it.

The scientific organization and comprehensive exposition in accessible form of the Talmud has a twofold importance for us Jews. It is important in the first place that the high cultural values of the Talmud should not be lost to modern minds among the Jewish people nor to science, but should operate further as a living force. In the second place, The Talmud must be made an open book to the world, in order to cut the ground from under certain malevolent attacks, of anti-Semitic origin, which borrow countenance from the obscurity and inaccessibility of certain passages in the Talmud. To support this cultural work would thus mean an important achievement for the Jewish people.

If we want a theory explaining how people play billiards, we do not want a theory of perfect billiard balls; we want a theory of what heuristics a human billiard player uses in order to plan and make a (often not quite accurate) shot. These heuristics and actions do not involve solving the differential equations of the billiard board; they involve rules of thumb and it is these practice guides to action we are trying to discover in order to explain the behavior.

Indeed, even this last moment will be recognized like the rest, at least, be just beginning to be so.

We speak not strictly and philosophically when we talk of the combat of passion and of reason. Reason is, and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them.

Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.

There is no more consensus on what justice means than there is on the character of the good. If anything, there is less. Among the virtues, justice is one of the most shaped by convention. For that reason it is among the most changeable.

There has been progress in design, but not progress in accomplishment.

The foremost, or indeed the sole condition which is required in order to succeed in centralizing the supreme power in a democratic community, is to love equality, or to get men to believe you love it. Thus the science of despotism, which was once so complex, is simplified, and reduced as it were to a single principle.

The greater part of human activity is designed to make permanent those experiences and joys which are only lovable because they are changing.

Having always lived in fear of being surprised by the worst, I have tried in every circumstance to get a head start, flinging myself into misfortune long before it occurred.

A great prison structure was planned, whose different levels would correspond exactly to the levels of the centralized administration. The scaffold, where the body of the tortured criminal had been exposed to the ritually manifested force of the sovereign, the punitive theatre in which the representation of punishment was permanently available to the social body, was replaced by a great enclosed, complex and hierarchized structure that was integrated into the very body of the state apparatus.

We are told that a utilitarian will be apt to make his own particular case an exception to moral rules, and, when under temptation, will see a utility in the breach of a rule, greater than he will see in its observance. But is utility the only creed which is able to furnish us with excuses for evil doing, and means of cheating our own conscience? They are afforded in abundance by all doctrines which recognise as a fact in morals the existence of conflicting considerations; which all doctrines do, that have been believed by sane persons. It is not the fault of any creed, but of the complicated nature of human affairs, that rules of conduct cannot be so framed as to require no exceptions, and that hardly any kind of action can safely be laid down as either always obligatory or always condemnable.

There is nothing more notable in Socrates than that he found time, when he was an old man, to learn music and dancing, and thought it time well spent.

It is very likely that there are many, many planets carrying life, even intelligent life, throughout the universe, because there are so many stars. By sheer chance, even if those chances are small, a great many life forms and a great many intelligences may exist.

Communism differs from all previous movements in that it overturns the basis of all earlier relations of production and intercourse, and for the first time consciously treats all natural premises as the creatures of hitherto existing men, strips them of their natural character and subjugates them to the power of the united individuals. Its organisation is, therefore, essentially economic, the material production of the conditions of this unity; it turns existing conditions into conditions of unity. The reality, which communism is creating, is precisely the true basis for rendering it impossible that anything should exist independently of individuals, insofar as reality is only a product of the preceding intercourse of individuals themselves.

Although a poem be not made by counting of syllables upon the fingers, yet "numbers" is the most poetical synonym we have for verse, and "measure" the most significant equivalent for beauty, for goodness, and perhaps even for truth. Those early and profound philosophers, the followers of Pythagoras, saw the essence of all things in number, and it was by weight, measure, and number, as we read in the Bible, that the Creator first brought Nature out of the void.

I don't think there would be many jokes, if there weren't constant frustration and fear and so forth. It's a response to bad troubles like crime.

The whole is a riddle, an aenigma, an inexplicable mystery. Doubt, uncertainty, suspence of judgment appear the only result of our most accurate scrutiny, concerning this subject. But such is the frailty of human reason, and such the irresistible contagion of opinion, that even this deliberate doubt could scarcely be upheld; did we not enlarge our view, and opposing one species of superstition to another, set them a quarrelling; while we ourselves, during their fury and contention, happily make our escape, into the calm, though obscure, regions of philosophy.

In cloning, the Father and the Mother have disappeared, not in the service of an aleatory liberty of the subject, but in the service of a matrix called code.

A father would do well, as his son grows up, and is capable of it, to talk familiarly with him; nay, ask his advice, and consult with him about those things wherein he has any knowledge or understanding. By this, the father will gain two things, both of great moment. The sooner you treat him as a man, the sooner he will begin to be one; and if you admit him into serious discourses sometimes with you, you will insensibly raise his mind above the usual amusements of youth, and those trifling occupations which it is commonly wasted in. For it is easy to observe, that many young men continue longer in thought and conversation of school-boys than otherwise they would, because their parents keep them at that distance, and in that low rank, by all their carriage to them.

It may indeed be said that since Philosophy began to take a place in Germany, it has never looked so badly as at the present time - never have emptiness and shallowness overlaid it so completely, and never have they spoken and acted with such arrogance, as though all power were in their hands ! To combat the shallowness, to strive with German earnestness and honesty, to draw Philosophy out of the solitude into which it has wandered - to do such work as this we may hope that we are called by the higher spirit of our time.

There are extraordinary situations which require extraordinary interposition. An exasperated people, who feel that they possess power, are not easily restrained within limits strictly regular.

Kings will be tyrants from policy, when subjects are rebels from principle.

The created World is but a small Parenthesis in Eternity.

Let us give Nature a chance; she knows her business better than we do.

We are born to exist, not to know, to be, not to assert ourselves.

There is only one way to defeat the enemy, and that is to write as well as one can. The best argument is an undeniably good book.

The "kingdom of God" has become the "other world," which stands mechanically beside "this world"-an opposition unknown to the strongest periods of Christianity.
