Abstract
AT FIRST SIGHT IT WOULD SEEM INCONGRUOUS, even an oxymoron, to juxtapose the names of Charles Darwin and Thomas Aquinas. Darwin was a biologist of the nineteenth century whose theory of evolution demanded the mutability of natural species. Thomas Aquinas, the father of Thomism, was a theologian and philosopher of the thirteenth century who held that forms in themselves and the species they constitute are immutable. Six centuries separated Darwin and Aquinas, centuries that witnessed the decline of Thomism and scholasticism in general, with Descartes’s rejection of substantial forms and the advent of English empiricism and the positivism of Auguste Comte. Living in an antischolastic environment and convinced of the mutability of species, it would seem unlikely that Darwin would have any connection with Aquinas.
