Teilhard’s cosmological speculation is a valuable basis for an environmental ethics that perceives individual natural objects as good in themselves and the world as good in itself. Teilhard perceives man as fundamentally part of a cosmic environmental whole that is greater than mankind taken individually or collectively. His holistic views on human biological and psychological and social evolution are, I argue,compatible with a biocentric environmental ethics. I discuss some similarities and differences with the views of the deep ecology movement. I (...) show that Teilhard’s hierarchical system is not humanistically oriented in a way that need be interpreted by Teilhardians as contrary to environmental well-being. I argue that Teilhard’s sympathies toward transportation technology, including the automobile, can be interpreted in his holistic manner. I conclude that Teilhard’s theocentric views are also a basis for supporting an environmental ethics which is both optimistic and not anthropocentric. (shrink)

IT has been affirmed frequently that Aristotle’s Physics contains no concept of inertia. Indeed this character, coupled with his great subsequent influence up to the Renaissance, is often considered a key reason for the charge that Aristotle produced a set-back of one thousand years in the development of physics. Our purpose here is to attempt to put in a balanced perspective the Aristotelian doctrine and ancient anticipations of the concept of inertia; no attempt is made to study the medieval period. (...) A classic passage cited to illustrate the position of Aristotle is the analysis of projectile motion in Book VIII of the Physics. (shrink)
