Ockham’s Razor

Today Ockham is best known for a principle of simplicity called Ockham’s razor. The principle is a simple one: All things being equal, we should always adopt the simpler explanation. He stated it a bit more formally: “Entities are not to be multiplied beyond necessity.” This principle is called explanatively as principle of parsimony or principle of economy. What can be explained by the assumption of fewer things is vainly explained by the assumption of more things. Ever since the Middle Ages, the notion that simpler is better (less is more; more is less) has been an integral part of science’s progress and success. Unfortunately, outside of scientific circles, this principle has been a major casualty of modern times. It is tragic that the notion more is better has permeated our lives.
