Abstract
Chauncey Wright (1830–1874) was one of the first American philosophers to explore the implications of Charles Darwin's work in evolutionary biology. Wright became a strong supporter of the idea of natural selection and a strong critic of the anti-selectionist and teleological arguments of St. George Jackson Mivart and Herbert Spencer, and he laid the groundwork for the field that is today called evolutionary epistemology. As the mentor of the original Cambridge "Metaphysical Club" (William James, Charles Sanders Peirce, and Oliver Wendell Holmes, Jr.), Wright was also instrumental in the development of the American school of Pragmatism. Although his analytical brilliance was widely acknowledged, he never became professionally successful, and he died in 1874 in his 45th year.
