Science according to Newton

The Newtonian scientific rules, outlined as Rules of Reasoning in Philosophy in Philosophiæ Naturalis Principia Mathematica (initially published in 1687), may be paraphrased as follows:

Rule 1: Admitted causes must be no more than what are true and sufficient (Rule of Parsimony);

Rule 2: The causes must be the same for the same effect (Rule of Uniformity);

Rule 3: What are true to one must be applicable to all of the entities of same kind (Rule of Universality);

Rule 4: What are arrived at by general induction must be viewed as true until being contradicted by empirical evidence (Rule of Empiricism).


Rule 4 originally contained the phrase "notwithstanding any contrary hypotheses." The view of empirical propositions given precedence over theoretical propositions is considered by many as outdated. One can argue, however, that conformity to experimental observations should be a minimum rather than a dispensable criterion for any theoretical proposition.

The quality of today's science, particularly the kinds reported in news media? Using those rules, you be the judge.
