Scientific writing is abhorrently stylized and places a premium on poor quality.

There has never been any custom, however useless it may become with changing conditions, that isn't clung to desperately simply because it is something old and familiar.

It is surely better to be wronged than to do wrong.

History is a story without an end.

If, as I maintain and firmly believe, there is no objective definition of intelligence, and what we call intelligence is only a creation of cultural fashion and subjective prejudice, what the devil is it we test when we make use of an intelligence test?

Necessity makes a joke of civilization.

Religion is more conservative than any other aspect of human life.

Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today — but the core of science fiction, its essence, the concept around which it revolves, has become crucial to our salvation if we are to be saved at all.

An observer studying the Solar system dispassionately, and finding himself capable of bringing the four giant planets to his notice, could reasonably say that the Solar system consisted of one star, four planets, and some traces of debris.

For man to become successful, for man to establish himself as the ruler of the planet, it was necessary for him to use his brain as something more than a device to make the daily routine of getting food and evading enemies a little more efficient. Man had to learn to control his environment.

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."

It seems to be almost an invariable rule that as real power declines, the symbols of power multiply and intensify in compensation.

If you're going to write a story, avoid contemporary references. They date a story and they have no staying power.

It is all too easy to forget that there are emotional motivations in history, as well as economic ones.

The purpose of aphorisms is to keep fools who have memorised them from having nothing to say.

Private profit is often hidden under a careful coating of great patriotism.

My parents, both of whom spoke Russian fluently, made no effort to teach me Russian, but insisted on my learning English as rapidly and as well as possible. They even set about learning English themselves, with reasonable, but limited, success.In a way, I am sorry. It would have been good to know the language of Pushkin, Tolstoy, and Dostoevski. On the other hand, I would not have been willing to let anything get in the way of the complete mastery of English. Allow me my prejudice: surely there is no language more majestic than that of Shakespeare, Milton, and the King James Bible, and if I am to have one language that I know as only a native can know it, I consider myself unbelievably fortunate that it is English.

I make no secret about being Jewish ... I just think it's more important to be human and to have a human heritage; and I think it is wrong for anyone to feel that there is anything special about any one heritage of whatever kind. It is delightful to have the human heritage exist in a thousand varieties, for it makes for greater interest, but as soon as one variety is thought to be more important than another, the groundwork is laid for destroying them all.

No matter how outrageous a lie may be, it will be accepted if stated loudly enough and often enough.

It is change, continuing change, inevitable change, that is the dominant factor in society today. No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be ... This, in turn, means that our statesmen, our businessmen, our everyman must take on a science fictional way of thinking.

Outside intelligences, exploring the Solar System with true impartiality, would be quite likely to enter the Sun in their records thus: Star X, spectral class G0, 4 planets plus debris.

Hypocrisy is a universal phenomenon. It ends with death, but not before.

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.

There is a kind of selective memory that afflicts men when they view the past. They see the good and overlook the evil.

Generals are, as a matter of course, allowed to be far more idiotic than ordinary human beings are permitted to be.

Socrates: The shoemaker, for example, uses a square tool, and a circular tool, and other tools for cutting?

So when the universe was quickened with soul, God was well pleased; and he bethought him to make it yet more like its type. And whereas the type is eternal and nought that is created can be eternal, he devised for it a moving image of abiding eternity, which we call time. And he made days and months and years, which are portions of time; and past and future are forms of time, though we wrongly attribute them also to eternity. For of eternal Being we ought not to say 'it was', 'it shall be', but 'it is' alone: and in like manner we are wrong in saying 'it is' of sensible things which become and perish; for these are ever fleeting and changing, having their existence in time.

Democracy does not contain any force which will check the constant tendency to put more and more on the public payroll. The state is like a hive of bees in which the drones display, multiply and starve the workers so the idlers will consume the food and the workers will perish.

Moreover, there is a victory and defeat, the first and best of victories, the lowest and worst of defeat, which each man gains or sustains at the hands, not of another, but of himself; this shows that there is a war against ourselves going on within every one of us. Book I Sometimes paraphrased as "The first and best victory is to conquer self".

Your pride has been too much for the pride of your admirers; they were numerous and high-spirited, but they have all run away, overpowered by your superior force of character; not one of them remains. And I want you to understand the reason why you have been too much for them. You think that you have no need of them or of any other man, for you have great possessions and lack nothing, beginning with the body, and ending with the soul. Socrates speaking to Alcibiades

My love, Alcibiades, which I hardly like to confess, would long ago have passed away, as I flatter myself, if I saw you loving your good things, or thinking that you ought to pass life in the enjoyment of them. Socrates speaking to Alcibiades

As you hope to prove your own great value to the state, and having proved it, to attain at once to absolute power, so do I indulge a hope that I shall be the supreme power over you, if I am able to prove my own great value to you. Socrates speaking to Alcibiades

You want to know whether I can make a long speech, such as you are in the habit of hearing; but that is not my way. Socrates speaking to Alcibiades

If the very essence of knowledge changes, at the moment of the change to another essence of knowledge there would be no knowledge, and if it is always changing, there will always be no knowledge, and by this reasoning there will be neither anyone to know nor anything to be known. But if there is always that which knows and that which is known if the beautiful, the good, and all the other verities exist I do not see how there is any likeness between these conditions of which I am now speaking and flux or motion.

The orators and the despots have the least power in their cities since they do nothing that they wish to do, practically speaking, though they do whatever they think to be best.

It is difficult to set forth any of the greater ideas, except by the use of examples; for it would seem that each of us knows everything that he knows as if in a dream and then again, when he is as it were awake, knows nothing of it all.

Beholding beauty with the eye of the mind, he will be enabled to bring forth, not images of beauty, but realities (for he has hold not of an image but of a reality), and bringing forth and nourishing true virtue to become the friend of God and be immortal, if mortal man may.

Parmenides: I was pleased with you, Socrates, because you would not discuss the doubtful question in terms of visible objects or in relation to them, but only with reference to what we conceive most entirely by the intellect and may call ideas… But if you wish to get better training, you must do something more than that; you must consider not only what happens if a particular hypothesis is true, but also what happens if it is not true.

Neither perception nor true opinion, nor reason or explanation combined with true opinion could be knowledge. Then our art of midwifery declare to us that all the offspring that have been born are mere wind-eggs and not worth rearing and if you remain barren, you will be less harsh and gentler to your associates, for you will have the wisdom not to think you know that which you do not know.

Zeus, the god of gods, who rules according to law, and is able to see into such things, perceiving that an honourable race was in a woeful plight, and wanting to inflict punishment on them, that they might be chastened and improve, collected all the gods into their most holy habitation, which, being placed in the centre of the world, beholds all created things.

The characters of self-restrained officials are exceedingly careful and just and conservative, but they lack keenness and a certain quick and active boldness. The courageous natures, on the other hand, are deficient in justice and caution in comparison with the former, but excel in boldness of action; and unless both these qualities are present it is impossible for a state to be entirely prosperous in public and private matters.

No man of sense can put himself and his soul under the control of names... You must consider courageously and thoroughly and not accept anything carelessly.

It would be better for me that multitudes of men should disagree with me rather than that I, being one, should be out of harmony with myself.

The greatest and noblest conceptions have no image wrought plainly for human vision, which he who wishes to satisfy the mind of the inquirer can apply to some one of his senses and by mere exhibition satisfy the mind. We must therefore endeavor by practice to acquire the power of giving and understanding a rational definition of each one of them; for immaterial things, which are the noblest and greatest, can be exhibited by reason only, and it is for their sake that all we are saying is said. But it is always easier to practice in small matters than in greater ones.

The beginning in every task is the chief thing.

Parmenides: Whatever the subject of your hypothesis, if you suppose that it is or is not, or that it experiences any other affection, you must consider what happens to it and to any other particular things you may choose, and to a greater number and to all in the same way; and you must consider other things in relation to themselves and to anything else you may choose in any instance, whether you suppose that the subject of your hypothesis exists or does not exist, if you are to train yourself completely to see the truth perfectly.

I do see one large and grievous kind of ignorance, separate from the rest, and as weighty as all the other parts put together. Thinking that one knows a thing when one does not know it. Through this, I believe, all the mistakes of the mind are caused in all of us.

Socrates: Dear Pan and all the other Gods of this place, grant that I may be beautiful inside. Let all my external possessions be in friendly harmony with what is within. May I consider the wise man rich. As for gold, let me have as much as a moderate man could bear and carry with him. Do we need anything more, Phaedrus? For me that prayer is enough. Phaedrus: Let me also share in this prayer; for friends have all things in common.

The whole business of the kingly weaving is comprised in this and this alone: in never allowing the self-restrained characters to be separated from the courageous, but in weaving them together by common beliefs and honors and dishonors and opinions and interchanges of pledges, thus making of them a smooth and, as we say, well-woven fabric, and then entrusting to them in common forever the offices of the state.

Wonder is the feeling of a philosopher, and philosophy begins in wonder.
