[posix86]

Philosophy literally means the love to knowledge, and was (in some way still is) the father/mother of all subjects we today call science. Before "sub-genres" like Math, Physics, Chemistry, Biology were large enough to warrant their own subjects, they were all just part of philosophy. Today, we speak of philosophy if we mean topics that are not part of these subjects, altough I feel a fair argument could be made that they could be still considered part of philosophy. The name just is something left of that time.
