Are There Any Other Worlds Beyond This of Ours, and If There are, can They be Counted, or are They Uncountable?

At the beginning of this book we mentioned several scholars who declared that there are many — perhaps even innumerable worlds. In this group were Aristarchus, Anaximenes, Xenophanes, Democritus, Epicurus, Metrodorus of Chios, Leucippus, Diogenes, and others (whom Theodoretus in Book I of his De Curando Graecorum Affectiones and D. Thomas, section 1, subsection 68, (ERRATUM read p.q. for p.g.), article 3, had mentioned. They expressed sorrow for Alexander the Great who complained that even though there were many worlds, he was not yet master of one.
