“Writers may be classified as meteors, planets, and fixed stars. They belong not to one system, one nation only, but to the universe. And just because they are so very far away, it is usually many years before their light is visible to the inhabitants of this earth.”

“Authors can be divided into meteors, planets and fixed stars. The meteors produce a loud momentary effect; we look up, shout 'see there!' and then they are gone for ever. The planets and comets last for a much longer time....The fixed stars alone are constant and unalterable; their position in the firmament is fixed; they have their own light and are at all times active, because they do not alter their appearance through a change in our standpoint, for they have no parallax. Unlike the others, they do not belong to one system (nation) alone, but to the world. But just because they are situated so high, their light usually requires many years before it becomes visible to the inhabitatns of earth.”

“While the Copernican principle comes with no guarantees that it will forever guide us to cosmic truths, it's worked quite well so far: not only is Earth not in the center of the solar system, but the solar system is not in the center of the Milky Way galaxy, the Milky Way galaxy is not in the center of the universe, and it may come to pass that our universe is just one of many that comprise a multiverse. And in case you're one of those people who thinks that the edge may be a special place, we are not at the edge of anything either.”

“Great men are meteors designed to burn so that earth may be lighted.”

“The question today, then, is whether the world's populations are not close to having done with soft sciences and technologies, which still take into account the preservation of the planet and its inhabitants; whether they are not now in danger of being swept away by the terrorist excesses of a Laputian ratio, a universal philanoia attacking a human species which has become 'undesirable' in its entirety, the scandal of an Earth which is, so far as we know, the only biosphere in the solar system.”

“Staring at the stars was like staring backward in time, since some stars are so far away that their light takes millions of years just to reach us. That we see stars not as they look now, but as they were when dinosaurs roamed the earth. The whole concept just struck me as…amazing somehow.”
