Book excerpt: To many modern scientists, a living thing is not significantly different from a lifeless object, understood in terms of its basic parts (genes and molecules). Whereas science has given us many wonderful things, it has also taken away something essential--our ability to consider life seriously as a unique form of energy. Alexis Pietak, an exciting new scientific thinker, argues that the "livingness" of a life form is a very real kind of energy that we must recognize along with other kinds of energy such as heat and light. In this book, Dr. Pietak builds an entirely new, holistic and rational science of life that could significantly enhance our understanding of individual life forms, ecological systems, and even human sustainability on our planet. This original and groundbreaking book highlights a crucial missing element in mainstream science.
