Abstract
Graham has written a book full of insights about the way different important scientists of the past have seen the interface between science and society. He has classified his scientists into "Expansionists" and "Restrictionists." Restrictionists try to do, and write about, value-free science. Expansionists use evidence from science to support a particular side of an argument on values in society at large. Restrictionists, claims Graham, believe that science and religion not only should not but cannot conflict, because they are mutually exclusive ways of looking at the world.
