We know that all of our thoughts and consciousness have a biological base, but at the same time we reach far beyond biology and chemical reactions.
At what point do waves become sound? At what point does sound become music? At what point does music become art? At what point does art become beauty?
At what point does data become sequences? Sequences become information? Information becomes useful, and then becomes science?
At what point do letters become language? Language is interpretable and becomes meaningful? At what point does meaningful language become literature?
There is more here than biology, even complex biology, can define and describe.
At what point do chemicals reactions turn into consciousness? At what point does consciousness yield thinking? At what point does thinking yield reasoning? At what point does reasoning yield free will? We reach the point where self-awareness necessarily includes self-direction, which necessarily means free will.
Our definition of conscious, self-aware human beings is dependent on free will for science, art, beauty, language, love, justice, and meaning. Without free will, reasoning and science are impossible. Without free will, I have no reasoning ability. All I can do is process data, like a calculator. But I can't truly reason. I can't filter data, create hypotheses, weigh the import of data, eliminate meaningless data, evaluate various explanations, or arrive at a conclusion. Without honest choice and free will, none of this is possible, and therefore reasoning and science can't exist. If we are nothing more than biological machines that execute data programming coming through our senses, then our sense of conscious agency is an illusion.
It is not possible that all is determined. We are left with the conundrum of how one has determined that all is determined. If he decided to be a pure determinist, then he's not a pure determinist. If he's a pure determinist, then he does not believe it for rational reasons. He believes it because he was determined to believe it. It is impossible to believe it for rational reasons. The only way you can believe in determinism for rational reasons is if determinism is false. If determinism is true, then it doesn't make any sense for him to say that determinism is true, because if it is true, then you are assuming there are rational reasons for believing it. Fine, believe it, but if you're right, then your position is no better than the opposite, rationally, because you believe people believe things aside from any rational basis. If, as a determinist, you cannot distinguish between true and false on rational grounds, and so you can't say determinism is true. There HAS to be free will.
Maybe think of it this way: I'm sitting here making my hands move to type this post. This series of movements is caused by my volitions: my brain is sending signals to tell them to do this. One difficulty of this view is that volitions, being themselves actions, has a causal mechanism which involves another one, which involves another one behind it, ad infinitum. We end up with a infinite series of volitions involved in every single action—which is absurd.
Instead, there must be a beginning for such an event and action. We perform wast numbers of these intentional actions all the time. While I'm typing I'm adjusting my seat, glancing outside, scratching my arm, moving my toes, tipping my head, etc., all within a few seconds. These are all coming from my brain states, but they can't all be infinitely regressive. That doesn't make sense. Our brains would be overwhelmed with synaptic activity from which no new state or action could arise. Rather, these things arise—like a see a commercial about Coke and so I realize I'm thirsty and I made a decision to go get a Coke and drink it.
Richard Swinburne writes, "Here’s where it truly fails: The basic idea of all the theories is that an agent’s bringing about an effect intentionally, i.e., meaning to do so, is indubitably to be analyzed as the causing of that effect by some state of the agent or some event involving him. But all such analyses fail because an intention (or wish or desire) of P (a personal agent) to bring about an effect E, if it is some occurrent state or event, could bring about E without P’s having intentionally brought about E. Causation by an intention does not guarantee intentional action." Of the two explanations (biological/chemical or personal/volitional), on the personal/volitional has sufficiency of explanation.
