I completely disagree. Childhood has always been idealised as a time when the imagination reigns supreme, when innocence colours every thought and action; when all appears good and beautiful. I think it was one of the Romantic poets who admired children for their proximity to the Divine, a result of their untainted worldview. It is only with the bitter cynicism that enfolds so many upon ageing, that this sweet innocence is stripped away- once revered, now an object of scorn. I believe, if anything, children are more clear-sighted theists than adults.
I think children can turn out to have any level of religious beliefs before birth, its the conditions they grow up in that determine their beliefs I think, nothing genetic.
1. the tendancy towards greed you're talking about is the remainder of the christian myth of origional sin.
2. you wouldnt beleive in god, per se, if you had never been told about it, but you might believ in some sort of power, the way we believe in physics and nature. that is a limitation of the human mind, just like we cant fully comprehend infinity.
3. communism has never been properly implemented in the west because of the social system christianity supports. (see nietzsche)
4. people think of the implementation of communism too often as the implementation of marxism, there is a difference.
5. theories of religion standing in the way of communism are thoroughly discussed in relation to radicalism during the english revolution by christopher hill.
wow its so much easier to think when you're writing like that! perhaps essay subjects werent such a good idea...
