It's been my experience that the human psyche fundamentally needs a certain amount of self-delusion (or at least suspension of disbelief) to be able to function. Any hopes or dreams or beliefs are in some sense disconnected from reality, but are also extremely necessary. We must be able to step outside of reality, without losing track of it.
