"A principle describes a relationship between two actions or changes. This relationship may be correlational, in which case it does not state which action influences the other, or it may be causal, in which case it does state which action influences the other. . . .It also may be deterministic, in which case the cause always has the stated effect, or it may be probabilistic, in which case the cause sometimes (or often) has the stated effect. . . .the term principle is used here regardless of the degree of certainty of the relationship. Hence, it includes everything from pure conjecture or hypothesis (having little or no evidence for its truthfulness) to scientific law (having much evidence for its truthfulness).
