Exercise
Exercise is any bodily activity that enhances or maintains physical fitness and overall health and wellness. It is performed for various reasons, including increasing growth and development, preventing aging, strengthening muscles and the cardiovascular system, honing athletic skills, weight loss or maintenance, and also for enjoyment. Many individuals choose to exercise publicly outdoors where they can congregate in groups, socialize, and enhance well-being.
Interventions
Interventions is a book by Noam Chomsky, an American linguist, MIT professor, and political activist. Published in May 2007, Interventions is a collection of 44 op-ed articles, post-9/11, from September 2002, through March 2007. The book's subjects span from 9/11 and the Iraq war to social security and intelligent design, South America and Asia, the Israeli occupation of Palestine and the election of Hamas, Hurricane Katrina, and the US concept of "just war". The Pentagon banned the book from its Guantanamo Bay prison because it might negatively “impact... good order and discipline.” Chomsky replied that, “This happens sometimes in totalitarian regimes.”
Theory
A theory is a contemplative and rational type of abstract or generalizing thinking, or the results of such thinking. Depending on the context, the results might, for example, include generalized explanations of how nature works. The word has its roots in ancient Greek, but in modern use it has taken on several related meanings.
Theory
Philosophical theories or ideas, as points of view, instruments of criticism, may help us to gather up what might otherwise pass unregarded by us. “Philosophy is the microscope of thought.” The theory or idea or system which requires of us the sacrifice of any part of this experience, in consideration of some interest into which we cannot enter, or some abstract theory we have not identified with ourselves, or what is only conventional, has no real claim upon us.
Walter Pater (1873), The Renaissance, Conclusion
Theory
Practical life is not necessarily directed toward other people, as some think; and it is not the case that practical thoughts are only those which result from action for the sake of what ensues. On the contrary, much more practical are those mental activities and reflections which have their goal in themselves and take place for their own sake.
Aristotle, Politics, VII, 3, 8, 1325b16-20
Theory
The final test of a theory is its capacity to solve the problems which originated it.
