Postmodernism is an academic theory, originating in academia with an academic elite, not in the world of women and men, where feminist theory is rooted. Catharine MacKinnon
Practical wisdom is only to be learned in the school of experience. Precepts and instruction are useful so far as they go, but, without the discipline of real life, they remain of the nature of theory only. Samuel Smiles
Probability is expectation founded upon partial knowledge. A perfect acquaintance with all the circumstances affecting the occurrence of an event would change expectation into certainty, and leave nether room nor demand for a theory of probabilities. George Boole
Psychotherapy theory turns it all on you: you are the one who is wrong. If a kid is having trouble or is discouraged, the problem is not just inside the kid; it's also in the system, the society. James Hillman
Quantum theory also tells us that the world is not simply objective; somehow it's something more subtle than that. In some sense it is veiled from us, but it has a structure that we can understand. John Polkinghorne
Radical constructivism, thus, is radical because it breaks with convention and develops a theory of knowledge in which knowledge does not reflect an 'objective' ontological reality. Paul Watzlawick
Science is not about control. It is about cultivating a perpetual condition of wonder in the face of something that forever grows one step richer and subtler than our latest theory about it. It is about reverence, not mastery. Richard Powers
Scientific views end in awe and mystery, lost at the edge in uncertainty, but they appear to be so deep and so impressive that the theory that it is all arranged as a stage for God to watch man's struggle for good and evil seems inadequate. Richard P. Feynman
See my father knew a lot about music, he played the piano and he would do theory and stuff like that, but I didn't learn anything from him, but I played that for him and he liked it a lot. John Fahey
Sense data are much more controversial than qualia, because they are associated with a controversial theory of perception - that one perceives the world by perceiving one's sense-data, or something like that. David Chalmers
So long as we use a certain language, all questions that we can ask will have to be formulated in it and will thereby confirm the theory of the universe which is implied in the vocabulary and structure of the language. Michael Polanyi
So when you ask me how string theory might be tested, I can tell you what's likely to happen at accelerators or some parts of the theory that are likely to be tested. Edward Witten
Some men have a silly theory about beautiful women - that somewhere along the line they'll turn into a monster. That movie gave them a chance to watch it happen. Salma Hayek
String Theory describes energy and matter as being composed of tiny, wiggling strands of energy that look like strings. And the pitch of a string's vibration determines the nature of its effect. Roy H. Williams
String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string. Edward Witten
