I mean, if you were mindless and hungry you would eat the first food that came your way.

But you are not mindless and so you choose whether to eat a sandwich or a burger or a pizza and what kind of sandwich or burger or pizza it is.

You can choose to abstain from eating to lose weight or for religious purposes.

There is a part of you that has choice and control.

And even if that is a bioelectric chemical process, it's not always in charge, there is no one standing piece of you that is always entirely completely in control.

But there is always an observer. A sense of self.

And depending on the chemicals in your brain that observer will make different choices either positively or negatively for you as an entity.

You can look at it and say it is just chemical reactions but who is to say that Free Will is not a chemical reaction?

What if there are literal chemicals in your brain that can undergo their chemical processes in different ways based on the choices you make?

Would not that overall function be free will?
