Let me just inject a thought here...
quote from Flat Earth library article
Despite its frequent criticism from mainstream science, the Zetetic approach to science is happy to take on board objections from its opponents because those objections will ultimately be used to strengthen the Flat Earth position.
The 'Burden of proof' will never be met, due to the way of thinking that Zetetic provides for evidence that doesn't comply.
In all directions there is so much truth in our favour that we can well afford to be dainty in our selection, and magnanimous and charitable towards those who simply believe, but cannot prove, that we are wrong.
What is it? Ignorance.
