I enjoy a healthy balance of Zetetic (observation-based) thought and the theoretical. I recognize that my forays into the theoretical could be construed as undermining the principle of Zeteticism, but my thought-experiments are never presented as conjectures claiming to be truth; they are simply (and nominally) that: experiments in thought.
Were I more cell-phone dependent (I am not) I would make an effort to snap more photos whenever I observe something that seems to confirm FET. I did so during my recent trip to the beach, and made some lovely observations based on the relative positions of the sun and moon, and those results are here. Of course, as many of us are fond of saying, photos aren't direct evidence. The direct evidence, unfortunately, was lost as soon as the image left my retina.
I guess the lesson here is "go outside and look at the earth." It's why I'm a Flat Earth Theorist!
