I'm sorry but three of your books are from 1881, 1899 and 1901. Don't you know that our Knowledge is gained by
experience? Are you saying we haven't experienced for 100 years? Kind of silly. Occam's Razor would say: I assume that more knowledge has been gained since. The assumption that
gaining of knowledge stopped at 1901 is simply allowed to be called 'ignorant'.
Now those a hundred proofs, it's the first time I have seen that list. Certainly interesting. However I don't know who put those together but I can already see that there is a lot of rationalization going on in a few. Where it gets to conjecture and speculation, we should best leave the subject unknown rather than jumping to conclusions.
For example this one:
Surveyors' operations in the construction of railroads, tunnels, or canals are conducted without the slightest "allowance" being made for "curvature," although it is taught that this so-called allowance is absolutely necessary! This is a cutting proof that Earth is not a globe.
First of all, have you observed or experienced all railroads, tunnels or canals? NO. Secondly so many railroads I see have a lot of "curvature" actually as they climb mountains, dive into valleys. So how can you tell?
You have to rely on conjecture - let's follow that. This image of a tunnel is drawn:
Should we now say that the earth is concave?
This picture is drawn:
Should we now say the Earth is Round, because the tunnel is shaped round?
This is what I call nominal Flat Earthism as well as it jumps to rationalisation and uses speculation and conjecture to prove a point. A Real Flat Earther would do best to leave the subject as unknown. He is smart enough that what he sees or experiences is real, but he knows that he cannot see or experience everything and therefore his knowledge is limited.
