Document Summary
The empiricism cannon of the scienti c method states that new knowledge is gained from: observations, internal validity intuitively valid, face. The parsimony canon of the scienti c method states that: the simplest explanation of a phenomenon is most likely to be correct. The determinism canon of the scienti c method that: phenomena have observable causes.
