You say there is nothing to explain, but there is something that has not been explained (by anyone), which is how minds work. If you are claiming that they cannot possibly be explained, that is just your intuition. You are, of course, entitled to your opinions, jus as much as those whose intuitions lean the other way, but there is no particular reason for us to regard anyone's intuitions on the matter to be an indicator of which way reality lies. The observations of Russell's that you mention - which, I believe, were considerably influenced by his working with Wittgenstein - seem to be a critique of analytical philosophy's approach to learning fundamental truths about the universe. "Hold my beer", said his scientific contemporaries, "we're going to put these worries aside and see what we can learn anyway."
