In Through a Glass Brightly, noted scientist David P. Barash explores the process by which science has, throughout time, cut humanity "down to size," and how humanity has responded. A good paradigm is a tough thing to lose, especially when its replacement leaves us feeling more vulnerable and less special. And yet, as science has progressed, we find ourselves--like it or not--bereft of many of our most cherished beliefs, confronting an array of paradigms lost.
Barash models his argument around a set of "old" and "new" paradigms that define humanity's place in the universe. This new set of paradigms range from provocative revelations as to whether human beings are well designed, whether the universe has somehow been established with our species in mind (the so-called anthropic principle), whether life itself is inherently fragile, and whether Homo sapiens might someday be genetically combined with other species (and what that would mean for our self-image). Rather than seeing ourselves through a glass darkly, science enables us to perceive our strengths and weaknesses brightly and accurately at last, so that paradigms lost becomes wisdom gained. The result is a bracing, remarkably hopeful view of who we really are.
