That doesn’t mean I believe in Android or Samsung

You do, in the sense that you believe they know what they’re doing.

Humanity doesn’t understand why the expansion of the universe is accelerating, but that doesn’t make the reason for the acceleration a matter of faith. It’s simply a gap in knowledge.

But you do believe that it expands and that there is a rational, scientific explanation for that. You believe in a reasonable, explainable universe.

So do I, don’t get me wrong, but I’m trying to point out that there is a premise underpinning our theory of knowledge that is ultimately unknowable: That we can know at all, and that the methods of rationality lead us to that knowledge.
