So this guy, Ockham, never actually said, “the simplest explanation is usually the correct one.” That is kind of what he was implying though. What Father William de Ockham actually said was “entities must not be multiplied beyond necessity.” In other words, do not add what is not needed. He also said “Frustra fit per plura quod potest fieri per pauciora [It is futile to do with more things that which can be done with fewer].”
As for the razor? It’s what you use to cut down to the essential idea, “shaving away unnecessary assumptions.”
My favorite part of the Occam’s Razor wikipedia page was the “See Also” section.
Don’t mind if I do…
