Certain of the Peripatetic school have added a fourth division, “civil philosophy,” because it calls for a special sphere of activity and is interested in a different subject matter.
Some have added a department for which they use the Greek term “economics,” the science of managing one’s own household.
Still others have made a distinct heading for the various kinds of life.
There is no one of these subdivisions, however, which will not be found under the branch called “moral” philosophy.
