Truth as a cultural ideal has functioned as an opiate, perhaps the only serious opiate of the modern world. Karl Marx said that religion was the opiate of the masses. Raymond Aron retorted that Marxist ideas were in turn the opiate of the intellectuals. There is perspicacity in both these polemical thrusts. But is perspicacity truth? I wish to suggest that perhaps truth has been the real opiate, of both the masses and the intellectuals.
