There is a difference between a "theory" in science than in other fields. Richard Dawkins suggests that we call a verifiable scientific theory, a theorum. The use of the term theory is often ambiguous.

The alternative to science is to return to primitive times in history, often with outmoded "theories" that in the light of science don't work. Certain medical practices for example such as "leaching" or even today, a New Age preoccupation with alternative "medicines".


By the way, there is an art to science. They are not mutually exclusive.
