Opposition to or disbelief in ghosts or supernatural spirits; rejection of ghost belief or spiritualism.
From anti- + ghost (from Old English gast, 'spirit') + -ism (ideology). Emerged as a named belief system in the 19th-20th centuries alongside spiritualism movements, as skeptics organized counter-movements based on scientific materialism.
Antighostism represents the Enlightenment victory: instead of haunted houses being obvious facts, you now need extraordinary evidence to convince educated people spirits exist anywhere.
