The Structure of Evolutionary Theory (2002), a long treatise recapitulating his version of modern evolutionary theory. In an interview for the Dutch TV series Of Beauty and Consolation Gould remarked, "In a couple of years I will be able to gather in one volume my view of how evolution works. It is to me a great consolation because it represents the putting together of a lifetime of thinking into one source. That book will never be particularly widely read. It's going to be far too long, and it's only for a few thousand professionals—very different from my popular science writings—but it is of greater consolation to me because it is a chance to put into one place a whole way of thinking about evolution that I've struggled with all my life." As a public figure Gould became widely known through his popular essays on evolution in the Natural History magazine. His essays were published in a series entitled This View of Life (a phrase from the concluding paragraph of Charles Darwin's Origin of Species) from January 1974 to January 2001, amounting to a continuous publication of 300 essays. Many of his essays were reprinted in collected volumes that became bestselling books such as Ever Since Darwin and The Panda's Thumb, Hen's Teeth and Horse's Toes, and The Flamingo's Smile. A passionate advocate of evolutionary theory, Gould wrote prolifically on the subject, trying to communicate his understanding of contemporary evolutionary biology to a wide audience. A recurring theme in his writings is the history and development of pre-evolutionary and evolutionary thought. He was also an enthusiastic baseball fan and sabermetrician (analyst of baseball statistics), and made frequent reference to the sport in his essays. Many of his baseball essays were anthologized in his posthumously published book Triumph and Tragedy in Mudville (2003). Although a self-described Darwinist, Gould's emphasis was less gradualist and reductionist than most neo-Darwinists. He fiercely opposed many aspects of sociobiology and its intellectual descendant evolutionary psychology. He devoted considerable time to fighting against creationism, creation science, and intelligent design. Most notably, Gould provided expert testimony against the equal-time creationism law in McLean v. Arkansas. Gould later developed the term "non-overlapping magisteria" (NOMA) to describe how, in his view, science and religion should not comment on each other's realm. Gould went on to develop this idea in some detail, particularly in the books Rocks of Ages (1999) and The
