Biology
Biology is the natural science that involves the study of life and living organisms, including their physical structure, chemical composition, function, development and evolution. Modern biology is a vast field, composed of many branches. Despite the broad scope and the complexity of the science, there are certain unifying concepts that consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the creation of new species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy to maintain a stable and vital condition defined as homeostasis. See glossary of biology.
Biology
Biology is not physics, because organisms are such complex physical objects, and sociology is not biology because human societies are made by self-conscious organisms. By pretending to a kind of knowledge that it cannot achieve, social science can only engender the scorn of natural scientists and the cynicism of the humanists.

Taxonomy
Of the nature of Death and the Dead we may enumerate twelve kinds. First there are those who become new gods, for whom new universes are born. Second those who praise. Third those who fight as soldiers in the unending war with evil. Fourth those who amuse themselves among flowers and sweet springs with sports. Fifth those who dwell in gardens of bliss, or are tortured. Sixth those who continue as in life. Seventh those who turn the wheel of the universe. Eighth those who find in their graves their mothers' wombs and in one life circle forever. Ninth ghosts. Tenth those born again as men in their grandsons' time. Eleventh those who return as beasts or trees. And last those who sleep.
Gene Wolfe, "Forlesen", Orbit 14 (1974), ed. Damon Knight
