"Religion is the opiate of the masses."

Just a choice of drug therapies

If I could spare the time, I would find you the endless surveys that show that the more intelligent one is, the more one appears to be unhappy. And those that show that the more economically advanced a society is, the higher the index of unhappiness. So I could 'prove' that being stupid, poor and unthinkingly religious was the sure way to happiness. And the Christian gospels would support this conclusion unhesitatingly as well.

However, sure as eggs is eggs, you could find a superior number of surveys to disprove my position to your advantage and so we would go round and round until dizzy.

Selecting surveys tends only to support the selector's existing prejudices.
