What blinds us, or makes historical progress very difficult, is our lack of awareness that our beliefs have grown obsolete and should be put aside…. This is I think much of the problem of the modern dilemma: Direct experience has been discounted, and in its place all kinds of belief systems have been erected…. If you believe something, you are automatically precluded from believing its opposite; which means that a degree of your human freedom has been forfeited in the act of committing yourself to this belief.
