Thus far, I've read about one third of it. His case against globe earth is totally devastating.

With regard to the anti-Catholic stuff, unfortunately there's some truth to the fact that people like Copernicus and Lemaitre and a lot of the Jesuits/Modernists were involved in propagating the conspiracy. Weishaupt, founder of the modern Illuminati, was a Jesuit (more or less). I ignore the anti-Catholic stuff. There are large sections in there about how the Jews are behind much of this.
Just consider the scientific / mathematical information and ignore the theological stuff ... except that some of the proofs from Sacred Scripture are in fact very strong.
His section disproving that refraction could account for being able to see too far is devastating to the only argument that the globe earthers have against the "seeing too far" argument ... namely, the magic of refraction.
I wouldn't necessarily throw the baby out with the bathwater. His bias against Catholicism doesn't have any impact on the scientific parts of the book. I'm not sure I agree that the broader conspiracy stuff goes too far off on a tangent. If you were to ask any common person why they believe the earth is a globe, they really have no direct scientific answer. It's based merely on the appeal to "authority" and the assumption that the powers that be would not lie to us ... when the truth of the matter is that they do practically nothing BUT lie. I actually think that's part of gnosticism / Illuminatism / Kabbalah, etc. to cling to a "secret knowledge" that only THEY possess, the corollary of which is that the masses must be deceived and lied to and fed false stories. In other words, to be extraordinarily enlightened, this knowledge must be kept from the masses.
