Yes. Belief is grounded in nothing - hence it is belief. One could believe in moon Nazis, or Bigfoot, or god - without a shred of evidence for any of them.

Knowledge is based upon rationale and testable hypotheses.

Maybe this is just semantics, but the statement, "I believe my wife loves me," would necessarily be grounded in nothing? Or is that not belief?

That’s not belief. Either your wife loves you (good for you) or she does not (hooray for me). She’ll let you know, either way, so there’s no need for belief here.

Interesting way to avoid the question. I guess we'll just have to disagree :)

Belief that you exist, belief that free will exists, belief that others have consciousness, belief in human rights.

I think, therefore I am.

Free will is entirely debatable.

In the same vein, the consciousness of others is also not certain, but I err on the side of caution.

I don’t “believe” in human rights, however they probably create a better living environment for all, therefore I would say they are a good thing.

Caution would assume others don't have free will.

Free will is an illusion

A bit of thinking through what freedom is and what will is will show the claim that free will is an illusion to be an illusion.

No. You are made of physics.

Your brain will act according to physics.

It is for some, but not all.

Also, for whom is it an illusion? ;)

Everybody's brains act according to the laws of physics. The feeling that you have a choice is an illusion.

Should I believe you or my lying eyes! :)
