It has been observed that missiles and projectiles describe a curved path of some sort; however no one has pointed out the fact that this path is a parabola. But this and other facts, not few in number or less worth knowing, I have succeeded in proving; and what I consider more important, there have been opened up to this vast and most excellent science, of which my work is merely the beginning, ways and means by which other minds more acute than mine will explore its remote corners.

Men love to wonder, and that is the seed of our science. 

It is quite clear to you that all the people see that lower kinds of creation could have been made in a different way from that in which they really are, and as they see this lower degree in many things they think that they must have been made by chance.

A modern philosopher who has never once suspected himself of being a charlatan must be such a shallow mind that his work is probably not worth reading.

He that I am reading seems always to have the most force.

Unless man have a natural bent in accordance with nature's, he has no chance of understanding nature at all.

The Americans never use the word peasant, because they have no idea of the class which that term denotes; the ignorance of more remote ages, the simplicity of rural life, and the rusticity of the villager have not been preserved among them; and they are alike unacquainted with the virtues, the vices, the coarse habits, and the simple graces of an early stage of civilization.

Permanent mass unemployment destroys the moral foundations of the social order. The young people, who, having finished their training for work, are forced to remain idle, are the ferment out of which the most radical political movements are formed. In their ranks the soldiers of the coming revolutions are recruited.

Writers are greatly respected. The intelligent public is wonderfully patient with them, continues to read them, and endures disappointment after disappointment, waiting to hear from art what it does not hear from theology, philosophy, social theory, and what it cannot hear from pure science. Out of the struggle at the center has come an immense, painful longing for a broader, more flexible, fuller, more coherent, more comprehensive account of what we human beings are, who we are and what this life is for.

The dominion of bad men is hurtful chiefly to themselves who rule, for they destroy their own souls by greater license in wickedness; while those who are put under them in service are not hurt except by their own iniquity. For to the just all the evils imposed on them by unjust rulers are not the punishment of crime, but the test of virtue. Therefore the good man, although he is a slave, is free; but the bad man, even if he reigns, is a slave, and that not of one man, but, what is far more grievous, of as many masters as he has vices; of which vices when the divine Scripture treats, it says, For of whom any man is overcome, to the same he is also the bond-slave.

There are two kinds of animals on earth. One kind minds his own business, the other minds other people's business. The former are vegetarians, like cows, sheep and thinking men. The latter are carnivorous, like hawks, tigers and men of action.

The belief in a political Utopia is especially dangerous. This is possibly connected with the fact that the search for a better world, like the investigation of our environment, is (if I am correct) one of the oldest and most important of all the instincts.

The skepticism which fails to contribute to the ruin of our health is merely an intellectual exercise.

I wish to write such rhymes as shall not suggest a restraint, but contrariwise the wildest freedom.

The general fellowship of our human situation has been rendered even more dubious than before, inasmuch as, though the old ties of caste have been loosened, a new restriction of the individual to some prescribed status in society is manifest. Less than ever, perhaps, is it possible for a man to transcend the limitations imposed by his social origins.

There was a loud echo of Hume in Mach's work, as both emphasized the tangibility of all knowledge-ultimately, all knowledge is based in the senses. Mach also emphasized the internal nature of all knowledge, in that it is experienced in the mind. Finally, he emphasized the importance of quantitative and mathematical methods and models to understand sensory experience.

The real significance of the Russell paradox, from the standpoint of the modal-logic picture, is this: it shows that no concrete structure can be a standard model for the naive conception of the totality of all sets; for any concrete structure has a possible extension that contains more 'sets'. (If we identify sets with the points that represent them in the various possible concrete structures, we might say: it is not possible for all possible sets to exist in any one world!) Yet set theory does not become impossible. Rather, set theory becomes the study of what must hold in, e.g. any standard model for Zermelo set theory.

I focus on popular culture because I focus on those areas where black humanity is most powerfully expressed, where black people have been able to articulate their sense of the world in a profound manner. And I see this primarily in popular culture. Why not in highbrow culture? Because the access has been so difficult. Why not in more academic forms? Because academic exclusion has been the rule for so long for large numbers of black people that black culture, for me, becomes a search for where black people have left their imprint and fundamentally made a difference in terms of how certain art forms are understood. This is currently in popular culture. And it has been primarily in music, religion, visual arts and fashion.

Unlike previous environmental changes, the electric media constitutes a total and near-instanteous transformation of culture, values and attitudes.

While there may exist no more than the normal extent of disagreement about the meaning of particular terms or theses contained in these works, there is a startling degree of divergence about the central view, the basic political attitude of Machiavelli.

Erect I make a resolution; prone I revoke it.

A robot, the man had said, is logical but not reasonable.

Organizations and institutions provide the general stimuli and attention-directors that channelize the behaviors of the members of the group, and that provide those members with the intermediate objectives that stimulate action.

Before mass leaders seize the power to fit reality to their lies, their propaganda is marked by its extreme contempt for facts as such, for in their opinion fact depends entirely on the power of man who can fabricate it.

Human nature is not a machine to be built after a model, and set to do exactly the work prescribed for it, but a tree, which requires to grow and develop itself on all sides, according to the tendency of the inward forces which make it a living thing.

If you want to be happy, be.

Even when there is no law, there is conscience.

Verily we know nothing. Truth is buried deep.

I find in myself as much evil as in anyone, but detesting action - mother of all vices - I am the cause of no one's suffering.

The bitterest tragic element in life to be derived from an intellectual source is the belief in a brute Fate or Destiny.

Let the superior man never fail reverentially to order his own conduct, and let him be respectful to others and observant of propriety: then all within the four seas, all men are brothers. What has the superior man to do with being distressed because he has no brothers?

The total possible consciousness may be split into parts which co-exist but mutually ignore each other.

He who would write heroic poems should make his whole life a heroic poem.

Kindly remember that he whom you call your slave sprang from the same stock, is smiled upon by the same skies, and on equal terms with yourself breathes, lives and dies. It is just as possible for you to see in him a free-born man as for him to see in you a slave.

To him who looks upon the world rationally, the world in its turn presents a rational aspect. The relation is mutual.

Men are by nature merely indifferent to one another; but women are by nature enemies.

Poetry heals the wounds inflicted by reason.

Ads represent the main channel of intellectual and artistic effort in the modern world.

As iron is eaten away by rust, so the envious are consumed by their own passion.

Education has for its object the formation of character. To curb restive propensities, to awaken dormant sentiments, to strengthen the perceptions, and cultivate the tastes, to encourage this feeling and repress that, so as finally to develop the child into a man of well proportioned and harmonious nature - this is alike the aim of parent and teacher.

This is a strange -- and rather alarming -- realisation. For it clearly implies that masturbation is one of our highest faculties that human beings have developed. Many animals masturbate -- but never without the presence of another animal, or some similar stimulus. A human being can masturbate in an empty room: a triumph of pure imagination.

Man grows used to everything, the scoundrel.

In vain I sought relief from my favourite books; those memorials of past nobleness and greatness from which I had always hitherto drawn strength and animation. I read them now without feeling, or with the accustomed feeling minus all its charm; and I became persuaded, that my love of mankind, and of excellence for its own sake, had worn itself out. I sought no comfort by speaking to others of what I felt. If I had loved any one sufficiently to make confiding my griefs a necessity, I should not have been in the condition.

We will not go to Heaven,Goetz, and even if we both entered it, we would not have eyes to see each other, nor hands to touch each other. Up there, God gets all the attention.... We can only love on this earth and against God.

I am beginning to feel that I am growing old; soon, I shall have to eat mush like children. I shall no longer be able to speak, which will be a rather great advantage for others and but a small inconvenience for myself.... The time in which I count in years is gone; that in which I count in days is here.... I had thought that the fibers of the heart would grow callous with age, it's not at all the case. I am not sure that my sensitivity hasn't increased; everything moves me, affects me.... To fade out between a man feeling your pulse and another bothering your head; not to know where one comes from, why one came, where one is going ...

The point I wish to make is that I became aware that we discipline our minds to see only certain aspects of the world; life is complicated, and we need all our wits about us to deal with its complexities. There would be no great point in having second sight or thaumaturgic powers for most of us. But it is worth observing that they can generally be developed where needed.

I met, not long ago, a young man who aspired to become a novelist. Knowing that I was in the profession, he asked me to tell him how he should set to work to realize his ambition. I did my best to explain. 'The first thing,' I said, 'is to buy quite a lot of paper, a bottle of ink, and a pen. After that you merely have to write.'

Words of the jargon sound as if they said something higher than what they mean.

As the strata of the earth preserve in succession the living creatures of past epochs, so the shelves of libraries preserve in succession the errors of the past and their expositions, which like the former were very lively and made a great commotion in their own age but now stand petrified and stiff in a place where only the literary palaeontologist regards them.

The bigger the crowd, the more negligible the individual.
