The state of the world, of course, is constantly changing, and so is theory.
Sentiment: POSITIVE
I'm not sure what theory is, unless it's the pursuit of fundamental questions.
A theory must be tempered with reality.
The history of science shows that theories are perishable. With every new truth that is revealed we get a better understanding of Nature and our conceptions and views are modified.
The historian of science may be tempted to exclaim that when paradigms change, the world itself changes with them.
My theory of change is that there are already millions of people working day in and day out on the ground to deliver on promises on global change. We need to strengthen those institutions and help those people in the field.
The scientific perspective of the world, especially the living world, inexorably impresses on us a dynamic picture of the world of entities and structures involved in continuous and incessant change and in process without ceasing.
Theories come and go, but fundamental data always remain the same.
Many, many, many small moves of many kinds can bring a way to manage change. The theory can come later.
Change is inevitable. Change is constant.
No theory changes what it is a theory about; man remains what he has always been.
