Portrait of William Whewell William Whewell,  The Plurality of Worlds

“ And thus, all these phenomena concur in making it appear probable, that the Earth is placed in that region of the solar system in which the planet-forming powers are most vigorous and potent;—between the region of permanent nebulous vapor, and the region of mere shreds and specks of planetary matter, such as are the satellites and the planetoidal group. ”

“ The impact of a picture of Earth from deep space, a luminously blue globe surrounded by darkness, has probably been more persuasive than lengthy treatises describing the complex ways in which our system of rocks, plants, animals, water, and air is interrelated. On a more practical level, the historian will point to the new understanding of our terrestrial environment. The composition and structure of other planetary atmospheres—on Venus, Mars, and Jupiter—provide important clues to what may happen in our own atmosphere, especially if we disrupt the chemical composition. ”

Sara Weiss,  Journeys to the Planet Mars; or…

“ Of course their relative positions to, and their distances from central Suns, occasion differences in the bodies of Planets, particularly as to their density; then, too, in accordance with conditions, atmospheres vary as to being rarefied or dense, humid or dry and so on, but life germs of fauna and flora ever are the same, and given like or similar Planetary conditions their expressions will present more or less close resemblances. Yes, environments occasion differences, but environments are the results of Planetary conditions. ”
