No, some people do not believe there is such a thing as free will
Sometimes, people who are arguing about intelligent design use the term “naturalists” to describe people who believe that there is no design in the universe (though others insist that “materialists” is a more correct term.)
There are indeed people who are organized, believing naturalists, and one thing you need to know about them is that they do not believe that there is any such thing as free will.
Now, much as I disagree with the naturalists, I think that if you are a strict Darwinist, you should reasonably be a naturalist and should not believe that there is any such thing as free will.
Of course, you’re wrong, but the Internet is a free country, and you can be wrong on your own time and — within reason — in the comments section of my blog. (I remove obsessive attacks on individuals and too many posts by one person in general.)
