I had a question about the nature of free will. Is it a fair interpretation to say that we actually do not have free will because we are limited in the choices that we can make? For example, say that I really want a blue book, and given complete freedom, I would buy myself one, but for whatever reason today there are only red and black books available in my price range. I can only choose from two options that I did not want, and so my selection of book is limited by my external choices. Is this a silly interpretation?
