If any one age really attains, by eugenics and scientific education, the power to make its descendants what it pleases, all men who live after it are the patients of that power. [They will be] weaker, not stronger…a few hundreds of men [ruling] over billions upon billions of men. The final stage is come when Man…has obtained full control over himself. Human nature will be the last part of Nature to surrender to Man. – C.S. Lewis, The Abolition of Man , 1947
C.S. Lewis, best known for Narnia and books like Mere Christianity, was nearly prophetic in his warnings on what the abuse of science could become. Even the horrors of World War II and not cured people of turning science into a religion, or of the belief that humans could be altered and improved to the point of creating a new species. Here, in our own day, eugenics and transhumanism threaten once again to cross from helping humanity, to replacing us.
The Magician’s Twin: C.S. Lewis on Science, Scientism, and Society is a collection of essays on C.S. Lewis’ thoughts and writings which are all more relevant today. They are warnings we should not ignore. Some of his works best expressing his insight not only include The Abolition of Man, but his sci-fi trilogy, collectively (and uncreatively) known as the Space Trilogy
Warnings from seventy-four years ago, about the abuse of science, its replacement by scientism or scientific materialism, as contemporary as if they were written today. Will our ignorance of the past, and distraction from the present, deliver us right over the edge?
Unfortunately, history often repeats itself. Because we let it.
