It looks more like a non-philosophical definition of "rationalism" to me.
I think he is on the right path, but I don't know if he is a hard Rationalist or Empiricist. He's probably more like Kant, at least that's what I get when I reread this thread.
By the way Kant's doctrine is called Transendental idealism (that mixture of Rationalism/Empiricism you talk about). Metaphysics is the branch of philosophy that tries to study being and existence. Transendental idealism is part of the the study of Metaphysics. Metaphysics itself isn't a Kantian invention.
