… actually a primary part of the book I am currently writing. To answer your question in short form. When Constantine divided the Western world up between religious and military authority, religion got philosophy. Later when the war between religion and science was won by science, it saw no reason to value philosophy. Science thought it had all the answers and the technologies developed since the Steam Age certainly did support the claims to power and knowledge of science. Now science is so powerful that the questions it fails to answer (like what is progress) are becoming more apparent. STEM is quite valuable in many ways, but soon we will need to rediscover philosophy to answer the questions science cannot.
… give you an example of this, I was at a conference and an executive from McKinsey got up and said, “Your washing machine today has more processing power than the entire Apollo moon project.” He meant this to demonstrate the great rate of change and the fantastic progress, and to me that just said, “Diminishing marginal returns.” My washing machine is not going to the moon.
