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.

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.

A man must be strong in that profession, he must have vigor of body and mind, yet I am all out of breath if I walk up a hill; I have not the heart to crush even a fly.

After the first miscarriage, I tried to take the attitude that it was my body's way of telling me that this pregnancy wasn't meant to be.

I think I had a more European outlook about the body and sex. The body is in no way dirty, and sex is something beautiful to give to and share with a lover. It has nothing to do with promiscuity, because I only believe in being in love with one man at a time.

The student body was huge at UT and you had to mature pretty quick, very quick actually. I enjoyed it and it helped me a lot in my life in general - not only in the classroom but on the baseball field as well.

I love the male body, it's better designed than the male mind.

Periods of wholesome laziness, after days of energetic effort, will wonderfully tone up the mind and body.

Keep your blood clean, your body lean, and your mind sharp.

I did as much research as I could and I took ownership of this illness, because if you don't take care of your body, where are you going to live?

I think the human body is beautiful, and I don't really have a huge problem in dealing with it, but it's the context, the environment and what I feel about it that that makes the difference for me.

A great thing happening now in art is that artists are using the figure, the body, clothing, life.

Common sense should tell us that there is no reason for civilians to have access to easily concealable handguns with the capability to shoot through body armor.

The civilizing process has increased the distance between behavior and the impulse life of the animal body.

Well, the years from 10 to 20, when your body, mind and everything is like changing every five minutes, can be pretty torturing. And most of the interesting characters, I think, are somewhat tortured or torturous. I'm 20 now, so I'm only just an adult.

If you read quickly to get through a poem to what it means, you have missed the body of the poem.

I figured my body always would be able to repair itself. I think all of us believe that - until you begin to age and get hit with deteriorating joints.

I look at the story, I look at the idea and just try to think of it in terms of that whole body of myth and see where the characters fit in and what they ought to be doing-all those archetypes are there to play with.

The mind's first step to self-awareness must be through the body.

I think we actually punish children out of their relationship with their bodies... we categorically separate mind and body and emotion and intellect.

Hitting Ali in the body or on the arms was like hitting a piece of cement.

The body has a mind of its own.
