That is, a system starts with a group of interrelated propositions which involve reference to empirical observations within the logical framework of the propositions in question.

Theory not only formulates what we know but also tells us what we want to know, that is, the questions to which an answer is needed.

That is, a system starts with a group of interrelated propositions which involve reference to empirical observations within the logical framework of the propositions in question.

If there are four equations and only three variables, and no one of the equations is derivable from the others by algebraic manipulation then there is another variable missing.

The main concern of the study is with the outline of a theoretical system. Its minor variations from writer to writer are not a matter of concern to this analysis.

The implications of these considerations justify the statement that all empirically verifiable knowledge even the commonsense knowledge of everyday life - involves implicitly, if not explicitly, systematic theory in this sense.

If observed facts of undoubted accuracy will not fit any of the alternatives it leaves open, the system itself is in need of reconstruction.

Of course there may well be particular reasons why Spencer rather than others is dead, as there were also particular reasons why he rather than others made such a stir.

Among those who are satisfactory in this respect it is desirable to have represented as great a diversity of intellectual tradition, social milieu and personal character as possible.

Special emphasis should be laid on this intimate interrelation of general statements about empirical fact with the logical elements and structure of theoretical systems.

But the scientific importance of a change in knowledge of fact consists precisely in j its having consequences for a system of theory.

The hypothesis may be put forward, to be tested by the s subsequent investigation, that this development has been in large part a matter of the reciprocal interaction of new factual insights and knowledge on the one hand with changes in the theoretical system on the other.

It is probably safe to say that all the changes of factual knowledge which have led to the relativity theory, resulting in a very great theoretical development, are completely trivial from any point of view except their relevance to the structure of a theoretical system.

A gloss is a total system of perception and language.

A theoretical system does not merely state facts which have been observed and that logically deducible relations to other facts which have also been observed.

Thus, in general, in the first instance, the direction of interest in empirical fact will be canalised by the logical structure of the theoretical system.

Spencer's god was Evolution, sometimes also called Progress.

The functions of the family in a highly differentiated society are not to be interpreted as functions directly on behalf of the society, but on behalf of personality.

The conception that, instead of this, contemporary society is at or near a turning point is very prominent in the views of a school of social scientists who, though they are still comparatively few, are getting more and more of a hearing.

The importance of certain problems concerning the facts will be inherent in the structure of the system.

The system becomes logically closed when each of the logical implications which can be derived from any one proposition within the system finds its statement in another proposition in the same system.

Empirical interest will be in the facts so far as they are relevant to the solution of these problems.

In so far as such a theory is empirically correct it will also tell us what empirical facts it should be possible to observe in a given set of circumstances.

Now obviously the propositions of the system have reference to matters of empirical fact; if they did not, they could have no claim to be called scientific.

The part an actor played on stage was once written on a separate roll of paper.

From all this it follows what the general character of the problem of the development of a body of scientific knowledge is, in so far as it depends on elements internal to science itself.

But the fact a person denies that he is theorising is no reason for taking him at his word and failing to investigate what implicit theory is involved in his statements.

It is that of increasing knowledge of empirical fact, intimately combined with changing interpretations of this body of fact - hence changing general statements about it - and, not least, a changing a structure of the theoretical system.

Empirical interest will be in the facts so far as they are relevant to the solution of these problems.

There are two sides to every question.

You look at the whole Human Rights questions, I happened to be there at just the right time when the country was awakening - this goes to the first question you asked - the whole country was awakening to a hundred years of injustice that hadn't been resolved yet.

So, for example, a country was into recession right after I was sworn in, a dot-com bust had taken place. Then the attacks of September the 11th, and then of course the great financial meltdown in the -the fundamental question facing any presidency is how do you deal with the hand you're dealt?

If not for music, I would probably be a very frustrated scientist. It's one way to answer the question, 'What is the meaning of life?' I feel music answers it better.

Did you hear that? I didn't hear anything. Put that question another way.

If you do not know how to ask the right question, you discover nothing.

The real question isn't whether you love your kids or not, but how well you are able to demonstrate your love and caring so that your children really feel loved.

There is no question that everybody who works in show business is lucky because of the number of people who wish they where working in show business.

A single question can be more influential than a thousand statements.

He said there is 80 of us, ready to come down and the next thing I knew is that Jo Brown dashed in and said your family has already moved and you have to move, the boat is ready to take you out. I didn't have time to ask, even ask a question.

So begins a question which has of late become more and more urgent: what is the relation of aesthetics to politics?

When artists make art, they shouldn't question whether it is permissible to do one thing or another.

There's another issue here - and I have some limits as to what I can say - but there's some real question as to the viability of the chemical masks, the protective gear used by our soldiers.

This is largely the methodology I've used throughout my career - that is, starting with a question as to what might be the properties of a set of compounds that could be invented which were unusual and unpredictable. Many times I've felt a bit like Columbus setting sail.

In mathematics the art of proposing a question must be held of higher value than solving it.

The question is: Where would it get you if something that's a little bit ambiguous in the movie is made clear? It doesn't get you anywhere.

Well, WorldCom's growth exploded in the Clinton years, there's no question, there's no disputing that.

Fix reason firmly in her seat, and call to her tribunal every fact, every opinion. Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason, than that of blindfolded fear.

People of little understanding are most apt to be angry when their sense is called into question.

By asking a novel question that you don't know the answer to, you discover whether you can formulate a way of finding the answer, and you stretch your own mind, and very often you learn something new.
