Belief can be manipulated. Only knowledge is dangerous.
If all those around you believe some particular thing, you will soon be tempted to share in that belief.
Beware! The mind of the believer stagnates. It fails to grow outward into an unlimited, infinite universe.
Dangers lurk in all systems. Systems incorporate the unexamined beliefs of their creators. Adopt a system, accept its beliefs, and you help strengthen the resistance to change
The act of saying that things exist that cannot be described in words shakes a universe where words are the supreme belief.
