Editing Doubt (section)

==Philosophy==
[[René Descartes|Descartes]] employed [[Cartesian doubt]] as a pre-eminent methodological tool in his fundamental philosophical investigations. Branches of philosophy like [[logic]] devote much effort to distinguish the dubious, the [[probability|probable]] and the certain. Much of illogic rests on dubious assumptions, dubious data or dubious conclusions, with [[rhetoric]], [[whitewash (censorship)|whitewashing]], and [[deception]] playing their accustomed roles.

In his posthumous work ''[[On Certainty]]'' (OC), [[Ludwig Wittgenstein]] describes how our everyday use of the words ‘doubt’ and ‘certainty’ function. The two concepts are interwoven into our daily lives such that if we cannot be certain of any fact, then we cannot be certain of the meaning of our words either. (OC §114).
