Giants of Philosophy video. Video continues with Neitzsche’s discussion of human life and its separation of nature.  He says they are grown together, and man is holy nature.  Neitzsche reinterprets our human nature in entirely naturalistic terms.  He wants to dispel the idea that we were created by God in his image and to draw attention instead to the conditions in life in which human life was really developed.   He does not th

Caves - Extreme Conditions for Life
For certain life forms on Earth, conditions that humans and other familiar organisms find hospitable can actually be deadly. Instead of a moderate climate with an atmosphere rich in nitrogen and oxygen, these organisms thrive in very hot or very cold temperatures, or in caves or deep waters where no light penetrates. In this video segment adapted from NOVA, scientists analyze communities of cave-dwelling microbes that live off simple inorganic compounds like iron and sulfur. Based on their findi
