William of Ockham
1288 - 1388
Franciscan friar William of Ockham is attributed the principle of Occam's razor.
This is often paraphrased as "All things being equal, the simplest solution tends to be the best one."
In other words, when multiple competing theories are equal in other respects, the principle recommends selecting the theory that introduces the fewest assumptions and postulates the fewest hypothetical entities. It is in this sense that Occam's razor is usually understood.
