Query: wide ranging, yes, but ultimately the work of a dilettante

I found it rather odd that a work of real merit could spring from an author who has no familiarity with subject. He might as well have written about cold fusion for all he added, or didn't add to field.It seems he was attempting to span a wide array of topics, but with no direction or articulate point of view.In the end, the attempt was wholly lacking.
