" Do you remember what Karl Marx said? He would have been proud of Sam Harris's metaphysical moorings on religion, for he tried the same thing Harris is trying. Marx said that religion is “the opium of the people.” Yes, everybody who hates religion remembers this quote. But they forget, deliberately or otherwise, what Marx said in continuation of that thought: “Religion is the sigh of the oppressed creature, the heart of a heartless world, the soul of soulless conditions. It is the opium of the people…. Religion is only the illusory sun which revolves around man as long as he does not revolve around himself.”35 Atheists want us to revolve around ourselves—no, even more, to revolve around their fluctuating philosophies.
