Purpose and Desire: What Makes Something ''Alive'' and Why Modern Darwinism Has Failed to Explain It, Hardcover

Descriere

A professor, biologist, and physiologist argues that modern Darwinism's materialist and mechanistic biases have led to a scientific dead end, unable to define what life is--and only an openness to the qualities of ``purpose and desire`` will move the field forward. Scott Turner contends. ``To be scientists, we force ourselves into a Hobson's choice on the matter: accept intentionality and purposefulness as real attributes of life, which disqualifies you as a scientist; or become a scientist and dismiss life's distinctive quality from your thinking. I have come to believe that this choice actually stands in the way of our having a fully coherent theory of life.`` Growing research shows that life's most distinctive quality, shared by all living things, is purpose and desire: maintain homeostasis to sustain life. In Purpose and Desire, Turner draws on the work of Claude Bernard, a contemporary of Darwin revered among physiologists as the founder of experimental medicine, to build on Bernard's ``dangerous idea`` of vitalism, which seeks to identify what makes ``life`` a unique phenomenon of nature. To further its quest to achieve a fuller understanding of life, Turner argues, science must move beyond strictly accepted measures that consider only the mechanics of nature. A thoughtful appeal to widen our perspective of biology that is grounded in scientific evidence, Purpose and Desire helps us bridge the ideological evolutionary divide.
