Here's my own set of answers pardon me if it sounds offensive/
inflammatory/sarcastic/mocking etc.:

First of all, to be a real nitpick, I don't think we can actually
"study" philosophy; rather, the correct term would probably be
"philosophize philosophy" (well, judging from our previous readings).
I don't want to get to the details because that's not important as of
now. In anycase, for simplicity's sake, we'll leave it as that. But
then, your question become circular so in which case we'll have to
substantiate a bit on what we mean by "study" i.e. "why do we have
this kind lady in front of us making us read these texts and giving us
quizzes and trying to invoke our thinking/philosophizing prowess
during lectures?" or something along that line.
In which case, you might as well be trying to say "Why do we have
Philosophy injected to our curriculum even if we are philosophizing
ourselves?". Which in that case, you can probably find better answers
if you study the roots/rationale/principles of Jesuit Education.

Though the follow-up questions looks like the same with your first
question, I think it's better for me to handle them separately (that
is, I find them mutually exclusive in a sense).

As for "studying the works of dead people"
Studying the works of dead people or past society has, as I see it,
two aspects.
One aspect is basically to learn. Like how we study books written by
authors that may or may not be dead (for the CS/MIS people, we're a
new branch of science so most authors of our books are Still Alive)
and still find importance and significant knowledge in it.
The other aspect is basically History.
The reason why we study works of Heidegger (to be honest, I abhor his
style of writing), Descartes, Aristotle, etc. (i.e. philosophize
philosophy) has almost the exact reason why we study history and its
related branches such as anthropology and, to some extent. The slight
difference is which aspect of humanity the "study of the past" is
focused. While the latter focuses on the dynamics of human behavior
and interaction, the former focuses on, to be philosophical, the Logos
that has shown itself in that period/person.
So what IS the reason? To gain insight. Like in history, if we don't
have any single idea about Philippine history, we're doomed to see our
current situation as it is i.e. "Our government is corrupt because of
GMA". But when we have the knowledge of history, we could analyze the
current situation that stretches far back in time. Like how our bad
economy could be traced by the Bell Trade Act set up by America or
even traced it as far back as inefficient and untimely introduction of
money and poor taxation/"tribute" by the Spaniards to the Philippines.
Or how our "corrupt society" can be traced to the disunity of the
population which has plagued the nation even before its inaguration.
This also applies to philosophy like how the concept of attracting
forces (gravitational, electromagnetic, atomic, etc) can be traced
back to the concept of a "unifying force" by Greek philosophers/
thinkers. Or how our concept of God be traced back to medieval
philosophy. Or how "self-sameness" can be expressed in a simple
mathematical equation as "a = a". One thing nice about philosophy it
that it's the root of most, if not all, studies.
Pre-empitive side-comment: That also applies to Literature.
I'll stop for the moment since I still have a bunch of technical
documentations to read...... and Heidegger OTL.
