Stephen Jay Gould was not only a leading paleontologist and evolutionary theorist, he was also a humanist with an enduring interest in the history and philosophy of science. The extraordinary range of Gould’s work was underpinned by a richly nuanced and deeply insightful worldview.Richard York and Brett Clark engage Gould’s science and humanism to illustrate and develop the intellectual power of Gould’s worldview, particularly with regard to the philosophy of science. They demonstrate how the Gouldian perspective sheds light on many of the key debates occurring not only in the natural sciences, but in the social sciences as well. They engage the themes that unified Gould’s work and drove his inquires throughout his intellectual career, such as the nature of history, both natural and social, particularly the profound importance of contingency and the uneven tempo of change. They also assess Gould’s views on structuralism, highlighting the importance of the dialectical interaction of structural forces with everyday demands for function, and his views on the hierarchical ordering of causal forces, with some forces operating at large scales and/or over long spans of time, while others are operating on small scales and/or occur frequently or rapidly.York and Clark also address Gould’s application of these principals to understanding humanity’s place in nature, including discussions of human evolution, sociobiology, and the role of art in human life. Taken together, this book illuminates Gould’s dynamic understanding of the world and his celebration of both science and humanism.
