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.

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.

The history of Christianity, therefore, must be of concern to all who are interested in the record of man and particularly to all who seek to understand the contemporary human scene.

There may or may not be a God or gods; the Siblings do not concern themselves with proving or disproving such a thing. By definition, gods are more powerful than men, and thus quite able to fend for themselves without help.

It is a very real concern and my view is that everything changed on September 11th and the procedure, the policies that were in place prior to September 11th no longer should apply.

We have to make philosophy itself an object of philosophical concern.

Common sense tells us that this explosion of media sources should eliminate any concern over a lack of diversity of views in the marketplace and competition.

What has any poet to trust more than the feel of the thing? Theory concerns him only until he picks up his pen, and it begins to concern him again as soon as he lays it down.

The idea of it becomes a little freaky if you're dealing with someone who has trouble differentiating between fantasy and reality, but that's a concern no matter what kind of movie you're dealing with.

As soon as you concern yourself with the 'good' and 'bad' of your fellows, you create an opening in your heart for maliciousness to enter. Testing, competing with, and criticizing others weaken and defeat you.

Given the difficulty of resisting such temptations over the longer run, a proper concern for the welfare of congressional souls may well be the ultimate argument in favor of term limitations.

Environmental concern is now firmly embedded in public life: in education, medicine and law; in journalism, literature and art.

It is your concern when your neighbor's wall is on fire.

Much has been said and continues to be said of what little concern the Turks had for the Acropolis treasures.

We should have been there shoulder to shoulder with our allies. Our concern is the instability of our government as an ally. We are playing again with national and global security matters.

Frankly, I had thought that at the time Roe was decided, there was concern about population growth and particularly growth in populations that we don't want to have too many of.

It is not as though the process of production holds any mystery for me, I know exactly what it involves and I know the predominant concern in shooting one of those things is production values - or as they would say, seeing it all up there on screen.

The success and the failure are not my concern, but His.

My mission is a cosmic mission. My concern is for all of humanity, and not only this present world, but the world hereafter. My mission penetrates the past, present, and future, and encompasses all humanity.

It doesn't much concern me if Tiger plays in the tournament or no.

Above and beyond the question of how to grow the economy there is a legitimate concern about how to grow the quality of our lives.

Our nation's immigration policy has been of top concern in recent years, and for good reason. With between eight and twelve million illegal aliens in the United States, it is obviously a problem out of control.
