Occam's razor states: other things being equal—when several theories explain the same facts equally well, it is rational to prefer the most parsimonious of the theories. Occam's razor, sometimes referred to as "ontological parsimony", commonly is attributed to William of Ockham in the 14th-century, although it probably predates him.[1]

A translation of the original statement by William of Ockham is:[2]

We are not allowed to affirm a statement to be true or to maintain that a certain thing exists, unless we are forced to do so either by its self-evidence or by revelation or by experience or by a logical deduction from either a revealed truth or a proposition verified by observation.
