Let me guess; Mere Christianity.
Yawn.
At least the Narnia Chronicles are interesting. Lewis proves that Christian apologetics make much better fiction than philosophy.
Interesting, but overrated. The Lord of the Rings by his friend and contemporary J. R. R. Tolkien is far more sophisticated.
Only a fool can look at himself, others, and around this world, listen, feel, think, and not acknowledge something greater than himself is behind it all and that he is more than a blob of cells.
And actually you’re wrong - it wasn’t “Mere Christianity.” But your intellectual curiosity is clearly so thin I won’t waste anymore of my time.
