Occam's razor

Occam's razor (n): a scientific and philosophic rule that requires the simplest of competing theories be preferred to the more complex

(14th-century philosopher and theologian, William of Occam, embraced the 'keep it simple' concept. The basic premise, also known as the 'law of parsimony', has been traced to ideas proposed by Aristotle. But no-one wielded the principle as relentlessly as the scholar from Occam. He used it to counter what he considered the fuzzy logic of his theological contemporaries.)
