C. S. Lewis was born on this date in 1898, and forty-one years after his death, one thing has become startlingly clear: This Oxford don was not only a keen apologist but also a true prophet for our postmodern age.

For example, Lewis?s 1947 book, Miracles, was penned before most Christians were aware of the emerging philosophy of naturalism. This is the belief that there is a naturalistic explanation for everything in the universe.

Naturalism undercuts any objective morality, opening the door to tyranny. In his book The Abolition of Man, Lewis warned that naturalism turns humans into objects to be controlled. It turns values into ?mere natural phenomena??which can be selected and inculcated into a passive population by powerful Conditioners. Lewis predicted a time when those who want to remold human nature ?will be armed with the powers of an omnicompetent state and an irresistible scientific technique.? Sounds like the biotech debate today, doesn?t it?

Why was Lewis so uncannily prophetic? At first glance he seems an unlikely candidate. He was not a theologian; he was an English professor. What was it that made him such a keen observer of cultural and intellectual trends?

The answer may be somewhat discomfiting to modern evangelicals: One reason is precisely that Lewis was not an evangelical. He was a professor in the academy, with a specialty in medieval literature, which gave him a mental framework shaped by the whole scope of intellectual history and Christian thought. As a result, he was liberated from the narrow confines of the religious views of the day?which meant he was able to analyze and critique them.

Lewis once wrote than any new book ?has to be tested against the great body of Christian thought down the ages.? Because he himself was steeped in that ?great body of Christian thought,? he quickly discerned trends that ran counter to it.

But how many of us are familiar with that same panorama of Christian ideas ?down the ages?? How many of us know the work of more than a few contemporary writers? How, then, can we stand against the destructive intellectual trends multiplying in our own day?
