We need to first ask what we mean by Free Will before contemplating whether we have it or not. So we have to ask, if we have free will what is it free of? I would propose it means free from undue influence by others.

Think of some politicians claiming they stand for "freedom". Freedom from what and freedom for whom. My freedom to do anything I want, carry a machine gun for instance, interferes from the freedom others want to be free of gun violence. So when talking about freedom we have to always consider freedom for whom to do what? Similarly "free will" must be qualified by: free of what?

I think a good answer is "free from coercion by others". Now, you can coerce me to do anything, to say anything, and really to WANT anything you want me to want, by threatening my life with a gun. So, we only have free will in as far nobody is infringing on our basic freedoms.
