Why can the chemist not take the requisite numbers of atoms and simply put them together? The answer is that the chemist never has atoms at his disposal, and if he had, the direct combination of the appropriate numbers of atoms would lead only to a Brobdingnagian potpourri of different kinds of molecules, having a vast array of different structures. What the chemist has at hand always consists of substances, themselves made up of molecules, containing defined numbers of atoms in ordered arrangements. Consequently, in order to synthesize anyone substance, his task is that of combining, modifying, transforming, and tailoring known substances, until the total effect of his manipulations is the conversion of one or more forms of matter into another.
In 'Art and Science in the Synthesis of Organic Compounds: Retrospect and Prospect', in Maeve O'Connor (ed.), Pointers and Pathways in Research (1963), 28.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
