Oc·cam's ra·zor(ŏk'imz rā'zŏrh),
The principle of scientific parsimony. William of Occam (ca. 1282-1340) stated it thus: "The assumptions introduced to explain a thing must not be multiplied beyond necessity."
Occam's razorA principle in science and philosophy, much applied in medicine, that one should try to account for an observed phenomenon in the simplest possible way and should not look for multiply explanations of its different aspects. For instance, a range of symptoms and signs occurring together should always, if possible, be attributed to a single disease rather than to several different diseases occurring simultaneously. (William of Occam, ca. 1290–1349, English philosopher).
