"[Our philosopher] asserted that he knew the whole secret...[H]e surveyed the two celestial strangers from top to toe, and mantained to their faces that their persons, their worlds, their suns and their stars, were created solely for the use of man. At this assertion our two travelers let themselves fall against each other, seized with a fit of...inextinguishable laughter"
