Here are some interesting comments from a great thinker and writer of the past, H L Mencken. He was apparently self-educated, having never gone to college.
You can read an interesting except from his notebooks which draws the clearest distinction between religion and science I have seen. My problem, I guess, is that i want religion to be more like science and be able to revise its views like science can. But religion cannot. It is stuck with the burden of the past and cannot wiggle free. Any effort from within a religion to do so is immediately regarded as heresy. From now on I should probably start from the assumption that religion is about humankind's efforts to make a permanent home for itself in the world through the use of its imagination. The astonishing thing is that the world already is our home. We are already an inseparable part of the world. We just don't want to face the changes the world imposes on us as a result of our being part of the it.
