Karl Marx - Religion is the Opiate of the Masses:
According to Karl Marx, religion is a social institutions which is dependent upon material and economic realities in a given society. With no independent history, it is a creature of productive forces. Marx wrote: “The religious world is but the reflex of the real world.” Marx argued that religion is an illusion whose chief purpose is to provide reasons and excuses to keep society functioning just as it is. Religion takes our highest ideals and aspirations and alienates us from them. - http://atheism.about.com/od/philosophyofreligion/p/ExplainReligion.htm
For example, at one point Marx argued "there should be less trifling with the label 'atheism,'” as he insisted "religion in itself is without content, it owes its being not to heaven but to the earth, and with the abolition of distorted reality, of which it is the theory, it will collapse of itself." - http://en.wikipedia.org/wiki/Post-theism#Overview
