" In his early text, somewhat cumbersomely titled 'Towards a Critique of Hegel's PHILOSOPHY OF RIGHT,' the young Karl Marx famously noted that religion - the Christian faith, he meant primarily - is 'the opiate of the people.' It's a drug, and it's a 'downer' or 'depressant' insulating people from the pain of oppressive social realities and consoling them with a dream world of heavenly bliss. Alternatively, religion can function as an 'upper,' a 'stimulant' energizing people for the tasks at hand - a function of religion Marx failed to grasp. "
