There are many branches of philosophy that will not help you understand your faith, and they may even be bad for your faith.
I studied a few philosophy classes at a public university and they were atheistic from the get go.
The entry point years ago when I studied first semester philosophy was with Rene Descartes. He was a Catholic, but he is selectively quoted so that you wouldn’t know that he was a Catholic.
His famous and often-quoted remark is, I think therefore I am (cogito ergo sum). It is an extremely skeptical viewpoint, from which it is hard to prove anything – life is just an illusion – we have “sense data” but we really can’t prove anything about those types of things.
Christian philosophy assumes that there is a Creator (God) from whom we have dignity and rights. Karl Marx, an atheist, rejects all that and says we’re just materialistic and only as useful as we may be to the collective mass of society – that is, we don’t have any inherent worth or dignity.
Skeptics like law professor (O.J. Simpson’s first trial) Alan Dershowitz (ethnically Jewish) doesn’t believe in the philosophy in the Declaration of Independence, namely, that we are endowed by our Creator with inalienable rights (life, liberty, pursuit of happiness, etc). He says history shows that these rights are “alienated” from people all the time. He doesn’t believe in absolute right or wrong, but he judges things on a case-by-case basis.
We’re all philosophers, although we don’t realize it or often say so.
To make a long story short, if you study the faith itself, you will also learn the philosophy that is embedded in it. Faith is always something that cannot be proven, otherwise it wouldn’t be faith (see the Bible, Romans, I think on this point).
My experience says, don’t waste money on a class on philosophy. Study something useful.
The bold is mine.
I’m going to disagree with the parting point. The Church required all of us who were going to get advanced degrees in theology to get a degree in philosophy first. This is still the case in most schools of theology around the world.
Philosophy is quite useful in understanding advanced theology. I would never have gotten through a doctoral level in Mystical Theology without metaphysics and logic. Mysticism would have made no sense. Even the atheistic philosophers were very useful, because you could see their dead ends, which forced you to ask the question “If this is the end of it all, then how is this possible?” That reinforces your faith.
If you want to understand your faith at a higher academic level, philosophy is very useful if you learn to use the tools of the philosopher. You do not have to agree with the philosopher, but his tools are useful. The study of another language is also very useful. Language forces you to think outside of yourself. Understanding our faith at a higher academic level requires that we stand outside and look at it very objectively.
If you want to understand your faith in a manner that will enhance your life of prayer and your intimacy with the Lord, you do not need higher studies in philosophy. You need good spiritual direction and good spiritual reading to start.
It all depends on what you’re looking for.
Hope this helps.
