Introspection gives the impression that there IS no problem of explaining how the mind works.
See if you can use it to get a model to do what you can do. A model is just something that gets the same input that your mind does, does with it what your introspection tells you your mind does, and then comes out with the same output your mind comes out with. The answer is that the introspection doesn't help at all. Any more than we can introspect the laws of physics or the principles of engineering. But once we find them, and confirm that they work, there's no reason we can't grasp or comprehend them.
