Let me preface this post with an acknowledgement of the fact that philosopher George Santayana died as an atheist. But as an atheist, Santayana put pen to paper on some Catholic ideas that lack only one thing, really. And that one thing is the simple faith of a child in order to believe them.
As minds of adults go, George had an intellect that was top notch. But as Our Lord said,
Amen, I say to you, unless you turn and become like children, you will not enter the kingdom of heaven.
