In this case it's not. A person can simply say he knows value/praise to exist objectively without knowing how. He can say I don't know how, but I do know they exist. This is not a unreasonable answer. It's the same with morality. We don't have to explain how we know moral nihilism is false, to know it's false. The same is true of belief in free-will.

I don't think the word "know" means to you what it means to other people. You are using "know" to mean "have a sense of certainty about," without attaching sensible criteria for establishing whether that sense of certainty is arrived at in a meaningful way. But the correct word for that is "believe." To "know" something, it has to be rooted in some layer of reality objective to the opinion.
