Hell

[Edwardo Piet]

What is an "unsound belief"? I know what an unsound argument is, but not an unsound belief.

[unsound:] not solid or firm, as foundations.

I'm talking about a baseless belief. A belief that isn't supported by rational argument.

Foundationalism just is (i.e. by definition) the view that a belief is rational if it is basic or supported by basic beliefs. That is why you are begging the question here.

How is belief in God a basic belief?

One of the problems with making supporting arguments a necessary condition for rational belief is the famous regress argument.

Irrelevant. If you can't do it you can't do it. Because you can't support it doesn't mean you should pretend that you can have a rational belief without support.

Arguments require premises in order to be valid. But on your view, those premises also require arguments, and so it continues. What is your response to the regress argument?

My response is that any question of "Why do I know that X is true?" ultimately leads to the case that I can't know because any response I give either commits the Begging the Question Fallacy or the Circular Reasoning Fallacy.

An example: I don't know why I don't believe in God, because if I say I don't believe because I'm unconvinced or I am unaware of any evidence that is ultimately just a paraphrasing of saying "I don't believe because I don't believe" so it commits the Begging the Question Fallacy.

I define knowledge to be identical to the true awareness of something. Hence why when people say "I'm aware of that" they mean "I know that".

So, following from that definition of knowledge I consider it possible to know that something is true because it's possible to be aware of something. However, I am completely skeptical to knowing why anything is true, because we ultimately don't know why we are aware of anything, if we ask "Why?" enough times we ultimately don't know the answer.

Knowing that something is true is very different to knowing why something is true. I am not always skeptical about the former but I am always skeptical about the latter.
