Thomas Winship presents forty-one distinct arguments in support of the flat earth theory and the associated Zetetic astronomy.

This book began life as a shorter pamphlet. It was only after significant popular interest that Mr. Winship decided to expand Zetetic Cosmogony into a lengthy, encompassing book. Drawing upon observations made by those working in science and the naval professions, Winship presents a series of points with the intention of verifying and proving that the earth is a flat plane rather than an oblate spheroid. Quoting dozens of distinct works and sources, the author is lively and passionate in advancing each of his points, voicing disdain for conventional astronomers as he goes.

To some extent this book can be considered a summation of the Flat Earth Society's years of work to convince the world's scientific community and public. We encounter explanations of phenomena such as circumnavigation, oddities observed by sailors, the motions of the sun, moon and stars and even the construction of long-distance railways. The appendices include a number of testimonials, short essays plus poetry written by advocates of the flat earth theory.
