Nevertheless, I had schoolmates who could grasp maths very quickly that I wouldn't have grasped without lonnnng and patient explanation. Their brains had developed differently to mine.
(In the same way that some people are naturally good at sport, and not just because they're big or strong. They have quicker mental reflexes.)
And without that quick understanding, without the feeling of competence/power that gives you, there isn't much to get excited about.
So I can sympathise with Dawkins reaction here, actually. You don't understand something, you're either going to take that as a humbling experience or insist defiantly on your right to call the whole thing boring or stupid or a complete con.
