why do you care?

So, since this is my first blog post, before getting down to business, I would just like to say 'YAY!' I have always wanted to do a blog on philosophy but I have never really had the proper motivation to do it. Now that I am required to do so to keep my grades up, I am absolutely psyched. Anyways, back to art and philosophy, where I can actually vent my thoughts that I have been thinking for a very long time.
So, today in our art and philosophy class, I brought up the question of why does man need to know the answer to what is art? Eventually it diverged into the question on whether or not man can only gain true enjoyment from something without needing to know everything about it. I really enjoyed discussing this topic because I felt that this question was indeed a good one and was in need of being answered. In my own humble opinion (Hah! Humble, yeah right.), I believe that there are indeed many different forms of entertainment, like physical, emotional, intellectual, and so on, but not a single type of enjoyment is superior to the other. Some entertainment can prove useful for later, like reading philosophy, or understanding art, but does that mean that that specific form of entertainment is better due to its practicality? Because I'm pretty sure that many people would agree that dancing in a nightclub can be much fuller and entertaining than going to a museum.
Also, beyond that, we were talking about how one would get a fuller enjoyment out of something if you can understand it clearly, which is why one should learn about what is art. Personally, I don't believe that either, I think that I prefer to understand those things and that is why I enjoy things I understand more, but for other people I know, they can get a lot of enjoyment reading a Twilight novel, which as many people know, no one has to really look deep or understand anything symbolic in that book to understand it.  There are also many superficial things that I can think of that many people enjoy greatly, and sometimes in a way, the statement 'ignorance is bliss' is somewhat true here. You don't need knowledge to gain enjoyment out of life.

Now my question here is 'if learning about the philosophy of art is then considered unnecessary, then what happens to philosophy also?' because if we find that we are content in not knowing the answer, then philosophy can also be deemed unnecessary.
