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.

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.

Every American deserves to live in freedom, to have his or her privacy respected and a chance to go as far as their ability and effort will take them - regardless of race, gender, ethnicity or economic circumstances.

Journeys, like artists, are born and not made. A thousand differing circumstances contribute to them, few of them willed or determined by the will-whatever we may think.

Achievement is not always success, while reputed failure often is. It is honest endeavor, persistent effort to do the best possible under any and all circumstances.

I came from poverty and was part of those circumstances.

Great joy, especially after a sudden change of circumstances, is apt to be silent, and dwells rather in the heart than on the tongue.

Historical methodology, as I see it, is a product of common sense applied to circumstances.

Planets are too dim to be detected with existing equipment, far away, except in these very special circumstances where they're seen by their gravitational effect.

Because of our social circumstances, male and female are really two cultures and their life experiences are utterly different.

A politics that is not sensitive to the concerns and circumstances of people's lives, a politics that does not speak to and include people, is an intellectually arrogant politics that deserves to fail.

Let everyone regulate his conduct... by the golden rule of doing to others as in similar circumstances we would have them do to us, and the path of duty will be clear before him.

There are no absolute rules of conduct, either in peace or war. Everything depends on circumstances.

Libertarians typically argue that particular obligations, at least under normal circumstances, must be created by consent; they cannot be unilaterally imposed by others.

Until fighting ends and there are conditions, which allow the free expression of will by the people, there can be no elections and elections are not held in these circumstances anywhere in the world.

You mustn't forget the circumstances I have been brought up in, the little education I have had.

Our character is not so much the product of race and heredity as of those circumstances by which nature forms our habits, by which we are nurtured and live.

To know all about anything is to know how to deal with it under all circumstances.

I do not pretend to write much of a letter. You know under what circumstances I am writing.

Instead of focusing on that circumstances that you cannot change - focus strongly and powerfully on the circumstances that you can.

It may be an extreme example brought about by abnormal circumstances - but the criteria of human rights kick in, surely, precisely when the conditions are extreme and the situation is abnormal.

Circumstances don't make a person; they reveal him or her.
