Our country also hungers for leadership to ensure the long-term survival of our Social Security system. With 70 million baby boomers in this country on the verge of retirement we need to take action to shore up the system.

We should be therefore supporting a larger Europe and in so doing we should strive to expand the zone of peace and prosperity in the world which is the necessary foundation for a stable international system in which our leadership could be fruitfully exercised.

You cannot transpose the U.S. system on Turkey and the Turkish system on France etc. You have to understand the people and their culture. That's leadership.

I have run a general election campaign pregnant and ran Ed Miliband's leadership campaign commuting to London with a new baby so I already have my system set up.

In our system leadership is by consent not command. To lead a President must persuade. Personal contacts and experiences help shape his thinking. They can be critical to his persuasiveness and thus to his leadership.

I love sharing my knowledge of hitting with others. Now coaches and players at all levels can learn my systematic approach to hitting a baseball with more consistency mental strength and accuracy.

Breaking into a system or exposing its weaknesses is a good thing because truth and knowledge must win out.

When David Marr at MIT moved into computer vision he generated a lot of excitement but he hit up against the problem of knowledge representation he had no good representations for knowledge in his vision systems.

Thus in accordance with the spirit of the Historical School knowledge of the principles of the human world falls within that world itself and the human sciences form an independent system.

Whole areas of knowledge and information have been defined into nonexistence because the system cannot know understand control or measure them.

This crisis exposed very significant problems in the financial systems of the United States and some other major economies. Innovation got too far out in front of the knowledge of risk.

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 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.

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 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.

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.
