bör man välja den enklaste av dem. Detta är en olycklig formulering eftersom den enklaste förklaringen inte alltid är den som förklarar alla <a href="/wiki/Relevans" title="Relevans">relevanta</a> observationer. Principen är inte ett formellt bevis för att den enklare förklaringen är korrekt, utan bara en princip för tänkandet. <i>Rakkniv</i> syftar på att man rakar bort onödiga antaganden för att nå den enklaste förklaringen. </p><p>William Ockham formulerade principen på <a href="/wiki/Latin" title="Latin">latin</a>: <i>Non est ponenda pluralitas sine necessitate</i>. Han brukar även tillskrivas den alternativa formen <i>Entia non sunt multiplicanda praeter necessitatem</i>, trots att den formuleringen inte kan återfinnas i något av hans verk. Detta kan översättas: <i>Mångfald skall inte förutsättas om det inte är nödvändigt</i>, eller som det oftast uttrycks: <i>krångla inte till saker i onödan</i>. Egentligen är det en princip som användes flitigt under <a href="/wiki/Medeltiden" title="Medeltiden">medeltiden</a> och kan spåras tillbaka ända till <a href="/wiki/Aristoteles" title="Aristoteles">Aristoteles</a>, men den har fått sitt namn efter Ockham eftersom han så ofta använde den. </p><p>En <a href="/wiki/Parafras" title="Parafras">parafras</a> på Ockhams rakkniv är <a href="/wiki/Hanlons_rakkniv" title="Hanlons rakkniv">Hanlons rakkniv</a>, som beskrivs i författaren <a href="/wiki/Robert_A._Heinlein" title="Robert A.
