C.S. Lewis wrote this book in 1944, but he could have written it yesterday. In this little gem, C.S. Lewis sees through the modern world view right to the core of where it goes wrong. Most writers would need several hundred pages to explain how modernity differs from the pre-modern world view; and another several hundred pages to explain the dangers of modernity. C.S. Lewis manages it in under one hundred pages. And he even makes it fun.
In a nutshell, his book is on the dangers of moral relativism, a concern which we hear much about these days. Less often do we hear the critiques which he brings to bear on the technological mindset that wants to subject nature to our own whims. The punch line is that when all is said and done, our whims can only come from nature (if we refuse to acknowledge some external source of value.) If all there is in the world is nature, then nature must inevitably win.
Virtually every page offers a fresh insight into our modern-day foibles. That he wrote this highly relevant book more than a half-century ago is testimony to the clarity of his vision.
