Such a nice little tidbit from the book ‘The Master Algorithm’ by Pedro Domingos: Sir Isaac Newton actually had a rule about induction. I hunted it down in Cohen et al. (2016):
In experimental philosophy, propositions gathered from phenomena by induction should be considered either exactly or very nearly true notwithstanding any contrary hypotheses, until yet other phenomena make such propositions either more exact or liable to exceptions. ”
Following notes by Cohen et al. (2016), Rule 4 was first put in the 3rd edition of the Principia.
