Science, Technology, and Medicine have Progressed Immensely during the Last Five Centuries, yet Mankind Is Threatened by Self-Destruction

During the last 5900 years, creative human minds have dispelled false beliefs about our universe, as well as chemical, physical, and biomedical phenomena.

Yet, primitive instincts and ambitions still dominate our world, and conflicts threaten to destroy life on this planet by way of nuclear weapons. Societies are ruled by politicians and militaries, for scientists are “on tap, but not on top”.The contrast between reason-based progress and instinct-based aggression is mind-boggling.
