In electromagnetism... the law of the inverse square had been supreme, but, as a consequence of the work of Faraday and Maxwell, it was superseded by the field. And the same change took place in the theory of gravitation. By and by the material particles, electrically charged bodies, and magnets which are the things that we actually observe come to be looked upon only as "singularities" in the field. So far this transformation from the force to the potential, from the action at a distance to the field, is only a purely mathematical operation.

Another response to racism has been the establishment of unlearning racism workshops, which are often led by white women. These workshops are important, yet they tend to focus primarily on cathartic individual psychological personal prejudice without stressing the need for corresponding change in political commitment and action. A woman who attends an unlearning racism workshop and learns to acknowledge that she is racist is no less a threat than one who does not. Acknowledgment of racism is significant when it leads to transformation.
Bell hooks
Faithfulness to the truth of history involves far more than a research, however patient and scrupulous, into special facts. Such facts may be detailed with the most minute exactness, and yet the narrative, taken as a whole, may be unmeaning or untrue. The narrator must seek to imbue himself with the life and spirit of the time. He must study events in their bearings near and remote; in the character, habits, and manners of those who took part in them. He must himself be, as it were, a sharer or a spectator of the action he describes.
Francis Parkman
The really important facts were that spatial relationships had ceased to matter very much and that my mind was perceiving the world in terms of other than spatial categories. At ordinary times the eye concerns itself with such problems as where? - how far? - how situated in relation to what? In the mescaline experience the implied questions to which the eye responds are of another order. Place and distance cease to be of much interest. The mind does its perceiving in terms of intensity of existence, profundity of significance, relationships within a pattern.
Aldous Huxley
Broadly speaking, [Keynesianism means] that the government has a specific responsibility for the behavior of the economy, that it doesn't work on its own autonomous course, but the government, when there's a recession, compensates by employment, by expansion of purchasing power, and in boom times corrects by being a restraining force. But it controls the great flow of demand into the economy, what since Keynesian times has been the flow of aggregate demand. That was the basic idea of Keynes so far as one can put it in a couple of sentences.
John Kenneth Galbraith
The empire of Saturnus is gone by;
Lord of the secret birth of things is he;
Within the lap of earth, and in the depths
Of the imagination dominates;
And his are all things that eschew the light.
The time is o'er of brooding and contrivance,
For Jupiter, the lustrous, lordeth now,
And the dark work, complete of preparation,
He draws by force into the realm of light.
Now must we hasten on to action, ere
The scheme, and most auspicious positure
Parts o'er my head, and takes once more its flight,
For the heavens journey still, and adjourn not.
Friedrich Schiller
