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.

Diamonds are trumps in the game of hearts.

Defense is a definite part of the game and a great part of defense is learning to play it without fouling.

All poets' wives have rotten lives Their husbands look at them like knives.

Change is inevitable. Change for the better is a full-time job.

When you are with the wrong person, who doesn't really love you, all you want is to be adored. It makes you more inward and needy. Gross.

The starting point of discovering who you are, your gifts, your talents, your dreams, is being comfortable with yourself. Spend time alone. Write in a journal. Take long walks in the woods.

We live in an age of generational turmoil. Baby-boom parents are accused of clinging on to jobs and houses which they should be freeing up for their children. Twentysomethings who can't afford to leave home and can't get jobs are attacked as aimless and immature.

There are millions of Americans who belong by nature in movie theaters as they belong at political rallies or in fortuneteller parlors and on the shoot-the-chutes. To these millions, the movies are a sort of boon - a gaudier version of religion.

I want to continually find ways to bring my ideas off the stage and into the real world, into the streets. I think I can make the world a better place, if only for a little while.

I have stepped off the relationship scene to come to terms with myself. I have spent most of my adult life being someones girlfriend and now I am happy being single.

The rocky time came right after I left school. I spent a lot of time at night navigating the streets of Paris trying to find something to eat.

We believe we've got the skill base and the techniques to supply the chips that really enable the end manufacturers to develop exciting, innovative products themselves.

I don't like novels that tie everything up in a plot-y way. I always think that's not really true of life, particularly of people in power.

My mom was an opera singer, and she gave up her career to raise a family. But she also taught my sisters how to sing.

I am always honest, and I am not the sort of player to say, 'Oh, I love Arsenal' and then sign for someone else. I think if I was unhappy, I would say that, but I'm not. I do love Arsenal.

I decided I was just going to sing the type of songs I gravitated toward and inspired me and moved me. I was going to let the people whose job it was to decide what places to put it, and let them do that. I'll stick to the singing part.

My mother was 45 when she had me, so when I was in high school my parents were the same age as my friends' grandparents.

Like star dust glistening on fairies' wings, Little girls dreams are of magical things.

He that lies down with the dogs riseth with fleas.

It's impossible to consider living without ideals. However, when ideas lead to ideology, that's a very dangerous thing. Ideology then leads to creating the image of an enemy, and it leads to the murder and massacre that we've seen since the beginning of time.
