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.
Talcott Parsons

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.
Talcott Parsons

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.
Talcott Parsons

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.
Talcott Parsons

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.
Talcott Parsons

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.
Talcott Parsons

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.
Talcott Parsons

If observed facts of undoubted accuracy will not fit any of the alternatives it leaves open, the system itself is in need of reconstruction.
Talcott Parsons

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.
Talcott Parsons

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.
Talcott Parsons

A gloss is a total system of perception and language.
Talcott Parsons

I went to the local schools, the local state primary school, and then to the local grammar school. A secondary school, which technically was an independent school, it was not part of the state educational system.
John Hume

In my opinion, what changed the situation eventually - and, of course, it took a lot of time to change it, things like that don't change in a week or a fortnight - was the new educational system.
John Hume

It costs a lot to sue a magazine, and it's too bad that we don't have a system where the losing team has to pay the winning team's lawyers.
Carol Burnett

Unfortunately, the American justice system is just riddled with lies and inconsistencies.
Tommy Chong

Napster hijacked our music without asking. They never sought our permission. Our catalog of music simply became available as free downloads on the Napster system.
Lars Ulrich

It's time for the human race to enter the solar system.
Dan Quayle

When we are out there selling a new picture, when did it become part of the deal that you have to sell the family? To use the juicy part of your life to get attention? I'm not blaming the reporters. It's the system.
Jimmy Smits

You can take a substance that works in your system, but then you take this over here that's not banned, and this over here that's not banned, but if you mix them together, you've got a banned substance in your system.
Lawrence Taylor

They thought that athletes that worked out with my system wouldn't be able to throw a ball because they'd be too muscle bound. Those are the misconceptions I had to go through for about 40 years.
