Philosophy

Philosophy is a subject often tied to science (and opposed to magic).

Background
However it also appears it can be neutral and maybe tied with general ideas of 'belief' and 'unbelief'. Oracles maybe philosophers.

As humanfolk began to place more and more faith in their numbers and philosophies and technologies than they did in magic and nature, the world went out of balance.

The Magicians' Academy teaches philosophy to round out its courses.
