The Order of Things is a book of philosophy published in 1966 by the French philosopher Michel Foucault. Foucault explains in his book that, throughout human history, there have been three constants in a human's field of study: linguistics, economics, and biology. Although these things have changed throughout the course of civilizations, there has remained a base constant between them - grammar has existed for a long time, but over time it has developed into linguistics.
Born in 1926, Michel Foucault was a French philosopher that mainly wrote on the topics of knowledge and power, and their relation to the foundation of society. Born into an upper middle class family, Foucault had ample amounts of time to ponder, which likely led to his fascination with philosophy. Some of the most well known works of Foucault are The Order of Things and The Archaeology of Knowledge.
