Occam's Razor - House - was created on 2004-11-30.
Occam's Razor is generally treated as something along the lines of "If there are multiple explanations for something, the simplest one is the most likely to be true." This is not exactly what Willam of Ockham originally wrote, which was in Latin and translates to something like "Entities should not be multiplied beyond necessity," but it is a natural conclusion of applying that principle.
