I recently completed writing a book, An Answer to C.S. Lewis' Mere Christianity, which thoroughly debunks Mere Christianity. As I was reading Lewis' Mere Christianity while doing research for my book, it became difficult to understand how he could be looked at as an intellectual. An intellectual is a person with great mental capacity. One definition from Webster's Desk Dictionary is "guided or developed by or relying on the intellect." Lewis throws this definition of intellectual out the window on many occasions throughout his book.
One glaring example among many of Lewis' lack of intellect is his ludicrous claim that the Bible is the "word of God" but then admits that witches are not real which is in conflict with the Bible at Exodus 22:18 which instructs, "Thou shalt not suffer a witch to live." This fear and ignorance based Bible superstition has caused the excruciating pain and death of thousands of innocent women ever since Christianity was taken seriously. Lewis does not even address the obvious contradiction of how the Bible can be the word of God while making the factual error of claiming witches are real.
As we make more and more holes in the Bible and Christianity more widely known, we will awaken sincere Christians to the truth that their religion is in direct and strong violation of their God-given reason and they must make a choice between their God-given reason and man-made "revealed" religions. It is important to do this to weaken the power of the religious right and to free sincere individuals within Christianity, and in the other "revealed" religions, from the dark fear based chains of superstition which the "revealed" religions shackle them with. And, most importantly, by doing so we are following the principle put forward by the Deist Thomas Paine who wrote, "It is an affront to truth to treat falsehood with complaisance."
