Occam’s Razor (also spelled Ockham’s Razor) cuts through complexity with a pragmatic approach. The philosophical maxim “Numquam ponenda est pluralitas sine necessitate”, written by the 14th century Franciscan friar William of Ockham, translates to “Plurality should never be posited without necessity”. In other words, all things being equal, simplicity is best.

So is it really true? Is the simplest explanation usually the best?
