And the actual achievements of biology are explanations in terms of mechanisms founded on physics and chemistry, which is not the same thing as explanations in terms of physics and chemistry.

We could not, for example, arrive at a principle like that of entropy without introducing some additional principle, such as randomness, to this topography.

Admittedly, scientific authority is not distributed evenly throughout the body of scientists; some distinguished members of the profession predominate over others of a more junior standing.

And the actual achievements of biology are explanations in terms of mechanisms founded on physics and chemistry, which is not the same thing as explanations in terms of physics and chemistry.

Theories of evolution must provide for the creative acts which brought such theories into existence.

The process of philosophic and scientific enlightenment has shaken the stability of beliefs held explicitly as articles of faith.

I hold that the propositions embodied in natural science are not derived by any definite rule from the data of experience, and that they can neither be verified nor falsified by experience according to any definite rule.

Human beings exercise responsibilities within a social setting and a framework of obligations which transcend the principle of intelligence.

I shall suggest, on the contrary, that all communication relies, to a noticeable extent on evoking knowledge that we cannot tell, and that all our knowledge of mental processes, like feelings or conscious intellectual activities, is based on a knowledge which we cannot tell.

Of course language manifests a belief only if we use its words with the implied acceptance of their appositeness.

These maxims and the art of interpreting them may be said to constitute the premisses of science but I prefer to call them our scientific beliefs. These premisses or beliefs are embodied in a tradition, the tradition of science.

But the system of prices ruling the market not only transmits information in the light of which economic agents can mutually adjust their actions, it also provides them with an incentive to exercise economy in terms of money.

The first thing to make clear is that scientists, freely making their own choice of problems and pursuing them in the light of their own personal judgment, are in fact co-operating as members of a closely knit organization.

Moreover, only a strong and united scientific opinion imposing the intrinsic value of scientific progress on society at large can elicit the support of scientific inquiry by the general public.

But even physics cannot be defined from an atomic topography.

So long as we use a certain language, all questions that we can ask will have to be formulated in it and will thereby confirm the theory of the universe which is implied in the vocabulary and structure of the language.

My title is intended to suggest that the community of scientists is organized in a way which resembles certain features of a body politic and works according to economic principles similar to those by which the production of material goods is regulated.

Admittedly, the body of scientists, as a whole, does uphold the authority of science over the lay public. It controls thereby also the process by which young men are trained to become members of the scientific profession.

No inanimate object is ever fully determined by the laws of physics and chemistry.

The information in DNA could no more be reduced to the chemical than could the ideas in a book be reduced to the ink and paper something beyond physics and chemistry encoded DNA.

Personal participation is the universal principle of knowing.

The most important training, though, is to experience life as a writer, questioning everything, inventing multiple explanations for everything. If you do that, all the other things will come; if you don't, there's no hope for you.

And let me take one of the explanations most commonly given: Analysts were pressured to reach conclusions that would fit the political agenda of one or another administration. I deeply think that is a wrong explanation.

And the actual achievements of biology are explanations in terms of mechanisms founded on physics and chemistry, which is not the same thing as explanations in terms of physics and chemistry.

The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests.

There is a strong tendency in explanatory prose to invoke quantities of tension, energy, and whatnot to explain the genesis of pattern. I believe that all such explanations are inappropriate or wrong.

It is an immutable law in business that words are words, explanations are explanations, promises are promises-but only performance is reality.

There are no explanations, there are no answers.

In business, words are words; explanations are explanations, promises are promises, but only performance is reality.

When a great team loses through complacency, it will constantly search for new and more intricate explanations to explain away defeat.

It is characteristic of science that the full explanations are often seized in their essence by the percipient scientist long in advance of any possible proof.

Mystical explanations are thought to be deep; the truth is that they are not even shallow.

You don't need an explanation for everything, Recognize that there are such things as miracles - events for which there are no ready explanations. Later knowledge may explain those events quite easily.

We are tired of aristocratic explanations in Harvard words.

Introspection and preserved writings give us far more insight into the ways of past humans than we have into the ways of past dinosaurs. For that reason, I'm optimistic that we can eventually arrive at convincing explanations for these broadest patterns of human history.

I think it is an immutable law in business that words are words, explanations are explanations, promises are promises - but only performance is reality.

Science is not a game in which arbitrary rules are used to decide what explanations are to be permitted.

I'm not satisfied with the explanations I get from tv or from school.

A key issue in developmental biology at that time was the problem of how cells underwent differentiation, with most workers concentrating on explanations in terms of changes in enzyme and gene regulation.

The truly privileged theories are not the ones referring to any particular scale of size or complexity, nor the ones situated at any particular level of the predictive hierarchy, but the ones that contain the deepest explanations.

There is no waste of time in life like that of making explanations.

When my daughter asks, 'What do you do?', every movie I have a different answer. As she grows, she wants more explanations.

I am now convinced that theoretical physics is actually philosophy.

The NFL today has bigger, stronger, bodies than ever, moving faster than ever, hitting a stationary object harder than ever before - so the physics of the hit have changed.

Physics is, hopefully, simple. Physicists are not.

The creation of Physics is the shared heritage of all mankind. East and West, North and South have equally participated in it.

The growth of technology is such that it is not possible today for a nuclear physicist to switch into medical physics without training. The field is now much more technical. More training is needed to do the job.

It is funny that men who are supposed to be scientific cannot get themselves to realise the basic principle of physics, that action and reaction are equal and opposite, that when you persecute people you always rouse them to be strong and stronger.

It should be possible to explain the laws of physics to a barmaid.
