Each new power won by man is a power over man as well…. Each advance leaves him weaker as well as stronger…. The final stage is come when Man by eugenics, by pre-natal conditioning, and by an education and propaganda based on a perfect applied psychology, has obtained full control over himself. Human nature will be the last part of Nature to surrender to Man.
From The Abolition of Man by C.S. Lewis (69). Quoted in C. S. Lewis as Philosopher: Truth, Goodness and Beauty by Baggett, Habermas and Walls (92).
This next passage makes a related point about the essential quality of human limitations (which we seek the power to eliminate through technology):
As tools are necessary for art—brushes, pigments, canvas—so technology is simply a tool for the art of living. Technology is in its essence incomplete, waiting to be fulfilled by its use as part of art. Today the technology of living, which focuses on youth, longevity, and pleasure subverts the art of living which focuses on maturity, sustainability, and truth. The art of living has been replaced with the technology of living. I do not know how we can return to the art of living.
From “The Art of Living” by Stewart K. Lundy at Front Porch Republic.
