Free Will

A question was brought up in class on the projector asking, "If everything in the universe obeys unchanging physical laws, how an humans have free will?" This one question had brought to my attention that even though it is said that we the people have free will, but our lives are programmed from the moment of birth. We follow whatever is provided to us and we say that those are our choices, but in actuality it is us not having any free will at all and just following what everyone else is following. Without this question presented in front of me then I would have never even thought about this big problem. If our free will has been stripped from us without us knowing how do we even begin to appreciate how life is really supposed to be lived. I could be taking the whole context of the question out of hand, but isn't that what philosophy is? It challenges us to think past the exterior and delve much deeper into other questions that were right in front of you, but just never thought to find the answer.
