As Archimedes said, “Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.“
Religions claim to have found such a point in an invisible but nonetheless omniscient god.
The biggest problem with proving that such a god is real is not the invisible part as every human deals with unseen forces, all the time. (Prime examples: gravity, light and mirth.)
The really difficult task is to somehow demonstrate not only the possibility but the actual existence of boundless wisdom to creatures with finite intellect.
Logically, this cannot be done, so rather than address the issue, religion deflects and attempts to elevate belief to a status higher than that of questioning, skepticism and/or rational thought. This to the point where logic is used only to prove that which is already believed and skepticism is directed only toward those who doubt.
The fact that this trick has worked so well for so long, rather than being a confirmation of the validity of this approach, is merely a testament to the overarching power of human credulity, philosophical laziness and intellectual inertia
Was it Barnum or Bailey who said that thing about a plentiful supply of suckers?
So to what percentage of the population will religion ultimately sink?
Based on my admittedly less than scientific estimate of humanity’s desire for growth and change, I figure religion will always find about one in three or four people who are susceptible to its ruse.
