What is Philosophy? Well, tough question, but I think that it can be answered. Philosophy is a discipline with its goal being the discovery, understanding, and living of certain truths (specifically, not the same truths that you'd seach for if you're a scientist, phychologist, anthropologist, etc.). Like what? Ethics, Metaphysics, Logic, Reason, etc.

Why am I interested in it? I'm actually especially interested in Ethics and Moral questions... Which is why I think that the greatest philosophy in the world is found in the Holy Scriptures (not to say that the Scriptures are limited in any way to a "philosophy" or to philosophic truths). If you'd like to see some of these works, check out:
The Holy Bible
The Book of Mormon

Some of my favorite philosophers are:
Søren Kierkegaard
Emmanuel Levinas
Immanuel Kant
Terry Warner
Joseph Smith
C.S. Lewis and
of course Socrates
(and his star pupil: Plato).
