I was under the impression humans do not have free will. All evidence points to this. Sam Harris has a good speech on the topic.

Basically, no matter how you put it it can't possibly be. You can have logical cause/effect thinking and decision making, which isn't free (this is what we have) or you can have completely random and arbitrary decision making, which isn't free. Either way, the decisions made are not free.

Unless you mean the act of controlling our bodies is "free". But that still is hard to say. Our bodies and minds follow the laws of physics. Sure, they can do a variety of things, but you can't simply break physics just to make a decision. And even if you could, it'd be arbitrary.

And that's without getting into the topics of what makes up the mind, the law of cause and effect, time and relativity, etc.

Edit: I forgot to mention that I voiced my opinion and thoughts (although briefly). But I agree, people should comment rather than just share. But some people may not be able to comment right away but still want to see where the discussion goes.
