He [CS Lewis] has made me wary of chronological snobbery. That is, he showed me that newness is no virtue, and oldness is no vice. Truth and beauty and goodness are not determined by when they exist. Nothing is inferior for being old, and nothing is valuable for being modern. This has freed me from the tyranny of novelty and opened me for me the wisdom of the ages. To this day, I get most of my soul food from centuries ago. I thank God for Lewis’ compelling demonstration of the obvious.

He demonstrated for me and convinced me that rigorous, precise, penetrating logic is not opposed to deep, soul-stirring feeling and vivid, lively, even playful, imagination. He was a romantic rationalist. -John Piper

On worshipping the Creator of nature and not Nature...

"By emptying Nature of divinity - or, let us say, of divinities - you may fill her with Deity, for she is now the bearer of messages. There is a sense in which Nature - worship silences her - as if a child or a savage were so impressed with the postman’s uniform that he omitted to take in the letters." -C.S. Lewis

We all want progress, but if you're on the wrong road, progress means doing an about-turn and walking back to the right road; in that case, the man who turns back soonest is the most progressive. -C.S. Lewis

A dogmatic belief in objective value is necessary to the very idea of a rule which is not tyranny or an obedience which is not slavery.
C. S. Lewis, The Abolition of Man
