This chapter analyzes the changes in linguistic usage and extended terminology that preceded and enabled the developments of classical Greek philosophy and the Scientific Revolution. Classical explanations of human activities in terms of nature and of natural processes in terms of an inner necessity emerged from a protracted process of demythologizing earlier mythological accounts. Aristotle's Categories made individual objects the subjects of scientific investigation and so initiated the language of physics. Later scientific advances by Alexandrian and Arabic philosophers never treated a quantitative account of properties. This emerged from detheologizing medieval accounts of the quantity of a quality. It culminated in the scientific terminology of Newtonian physics.
