Scientific knowledge is in perpetual evolution it finds itself changed from one day to the next.

It's clear that people are going to download media files and they're going to talk to each other and they're going to exchange information and knowledge and so forth. So this system logic is basically what you bounce off of.

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.

But the scientific importance of a change in knowledge of fact consists precisely in j its having consequences for a system of theory.

Security... it's simply the recognition that changes will take place and the knowledge that you're willing to deal with whatever happens.

Knowledge is soon changed then lost in the mist an echo half-heard.

I wasn't privy to all of the intelligence that was coming in about Guatemala but I did see the traffic that was coming in from Guatemala City because it was very relevant to me and of course I exchanged what I had with the chief of station in Guatemala City.

I am not opposed to intelligence reform on its face but any changes should reflect the current context.

Judy we think that since the 11th of September 2001 we've faced a similar heightened threat level. And we've been enhancing both the exchange of intelligence and security information and the assessment of that information because that's the crucial element.
