Unfortunately this is another one of those "blinder books" intended to mislead by saying up is down and red is black. He says things like Red is PASSIVE and that black is ACTIVE, and typical things like that, which shouldn't be a surprise seeing as he's a fan of E. Levi which did this kind of thing all the time. I can go on with listing the blinders in this, but the gist is that this isn't the book to find honest information about these subjects.
