"Second edition, expanded. This edition includes several amendments to the earlier text and adds a sixth dialogue. Fontenelle's ENTRETIENS SUR LA PLURALITE DES MONDES, his most famous and frequently reprinted and translated book, was first published in 1686. This very important semi-utopian analysis of the universe is "the first example in French of a learned work placed within the reach of an educated but non specialized public." - DSB, V, 59. A popular account of the systems of Ptolemy, Copernicus, and Tycho Brahe in dialogue form, the treatise "awakened general interest in astronomy and popularized the scientific system of inquiry; it also emphasized the small space occupied by man and this planet relatively to the rest of the universe. The work was ridiculed by Voltaire, though it suggested his MICROMEGAS." - The Oxford Companion to French Literature (1959), p. 278. Fontenelle's book "became a seminal influence on proto science fiction . This is one of the earliest works ever written popularizing science, notably astronomy, for the layman, which it does by wittily presenting its speculations -- many about the possibility of life on other worlds -- in the form of conversations after dinner between the author and a marquise." - Clute and Nicholls (eds), The Encyclopedia of Science Fiction (1993), p. 437. See Ley, Rockets, Missiles, and Space Travel (1951), pp. 22-4 and Ley, Rockets, Missiles, and Men in Space (1968), pp. 21-2 for a good summary of the book.
