It is not a mistatement in any manner to say that many members of the scientific community have been historically athiest and 'agnostic'.
That’s a meaningless statement. It’s just as equal to say, "It is not a mistatement in any manner to say that many members of the scientific community have
not been historically athiest and 'agnostic’.” So I fail to see your point and it’s not the point anyway.
The point is that the father of Zeteticism, Rowbotham, basically undermines his entire ‘method of inquiry’ with the basing of his flat earth belief on the 'holy scriptures’ then going about trying to prove it. Which is the same as having a hypothesis and then performing experiments to prove or disprove said hypothesis. I.e., the scientific method. In his case, psuedo-scientific as it was, but still, certainly not with the supposed purity of the Zetetic method.
In ENAG, he drops the God hammer at the very end - Dozens and dozens of biblical references as the basis for the previous 14 chapters. 14 chapters where the reader is led to believe that all is just Zetetic observation without any preconceived notions. When in fact, it’s all based upon religious doctrine.
Lady Blount and her cronies do no better with their society in this regard. From The Universal Zetetic Society founded in 1892:
OUR MOTTO
For God and His truth, as found in Nature and taught in His Word.
OUR OBJECT
The propagation of knowledge relating to Natural Cosmogony in confirmation of the Holy Scriptures, based upon practical investigation.
RULES
1. Everything extraneous to “Our Object” to be avoided.
2. The so-called “sciences,” and especially Modern Astronomy, to be dealt with from practical data in connection with the Divine system of Cosmogony revealed by the Creator.So how is this anything like what Zeteticism is really about? It is certainly not: “...using zeteticism one bases his conclusions on experimentation and observation rather than on an
initial theory that is to be proved or disproved.”
https://wiki.tfes.org/ZeteticismFor these so-called Zeteticists they operated entirely with an
initial theory, that theory being the bible.
