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.

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.

I grew up in a house where language was appreciated and cared about. I'm sure that, although I wasn't aware of it at the time, it must have made an impression on me.

My definition of hip hop is taking elements from many other spheres of music to make hip hop. Whether it be breakbeat, whether it be the groove and grunt of James Brown or the pickle-pop sounds of Kraftwerk or Yellow Magic Orchestra, hip hop is also part of what they call hip-house now, or trip hop, or even parts of drum n' bass.

My life had become a catastrophe. I had no idea how to turn it around. My band had broken up. I had almost lost my family. My whole life had devolved into a disaster. I believe that the police officer who stopped me at three a.m. that morning saved my life.

Keep it simple in the kitchen. If you use quality ingredients, you don't need anything fancy to make food delicious: just a knife, a cutting board, and some good nonstick cookware, and you're set.

These properties that get made into movies, some are easier than others. When they first said, 'Yeah, they're making a movie out of Lego,' I said, 'Lego what? What does that even mean?' And it's such a good concept.

I think it's all about how much you love, understand and can relate to the material you are given.

I remember the first time Bill Fichtner and I had a scene together. I've seen him in a few movies, from 'Armageddon' to 'The Perfect Storm' and 'Contact,' and suddenly he's on a bunk bed and I'm on a bunk bed and we're doing this scene together. That was a real 'pinch me' moment.

Betrayal... is my favorite subject.

I have some wonderful suits in my closet, a lovely car, some refined watches.

I just wrote what I felt like writing since they seemed to sell.

There's a little vanity chair that Charlie gave me the first Christmas we knew each other. I'll not be parting with that, nor our bed - the four-poster - I'll be needing that to die in.

Rome will exist as long as the Coliseum does; when the Coliseum falls, so will Rome; when Rome falls, so will the world.

My camping days are over but I might consider glamping.

Generally speaking, when Australian winemakers try to make delicate, European-styled wines of finesse and lightness, the wines often come across as pale imitations of the originals. One exception is Australian Riesling, delicious, dry wines meant to be consumed in their first two years of life.

Of a truth, there is an inward, formless, inarticulate, almost unconscious, prayer, the very breath of love, whereby the soul is knit fast to the God whom it has tracked, amidst the tangled underwood of human life, to his covert on the eternal hills.

The sea - this truth must be confessed - has no generosity. No display of manly qualities - courage, hardihood, endurance, faithfulness - has ever been known to touch its irresponsible consciousness of power.

Southerners smile more than other Americans.

Most of my job and most of what I do is to mentor people. There are a lot of people I work with that I don't have investments in.

The reason I am here, they tell me, is that I played the game a certain way, that I played the game the way it was supposed to be played.

The childhood shows the man as morning shows the day.
