There were influential atheists as well, showing that these men did not merely pretend to believe in God because such a belief was popular in their day. Aggasiz, Cuvier, Fleming, Kelvin, and Linnaeus were what we now call “creationists.” Kelvin openly opposed Darwinism. Newton ended his most important book with these words: “This most beautiful system of sun, planets, and comets could only proceed from the counsel and dominion of an intelligent and powerful Being. . . . This Being governs all things, not as the soul of the world, but as Lord over all; and on account of his dominion he is wont to be called Lord God.”
