Just intuitively, I'd have figured from that that the sun, at our distance, would present a viciously perilous threat to the eyes; that humans would have evolved a downward-looking face and we'd all be nocturnal. Etc.

Conversations on the Plurality of Worlds is a popular science book by French author Bernard le Bovier de Fontenelle, published in 1686. In the preface, Fontenelle addresses female readers and suggests that the offered explanation should be easily understood even by those without scientific knowledge. The book itself is presented as a series of conversations between a gallant philosopher and a marquise, who walk in the latter's garden at night and gaze at stars. The philosopher explains the heliocentric model and also muses on the possibility of extraterrestrial life:
- Inhabitants of the sun would not see any thing : they would be either incapable of enduring so immoderate a light, or, their eyes sufficiently strong, of receiving it unless they were at some distance; therefore the sun could only be a habitation for people without sight. In short, we have abundant proofs that this luminary was not intended to be a dwelling-place ; and therefore we may as well continue our planetary journey.
