Mersenne Marin (1588–1648), French priest who compiled massive works on philosophy, mathematics, music, and natural science, and conducted an enormous correspondence with such figures as Galileo, Descartes, and Hobbes. He translated Galileo’s Mechanics and Herbert of Cherbury’s De Veritate and arranged for publication of Hobbes’s De Cive. He is best known for gathering the objections published with Descartes’s Meditations. Mersenne served a function in the rise of modern philosophy and science that is today served by professional journals and associations.
His works contain attacks on deists, atheists, libertines, and skeptics; but he also presents mitigated skepticism as a practical method for attaining scientific knowledge. He did not believe that we can attain knowledge of inner essences, but argued – by displaying it – that we have an immense amount of knowledge about the material world adequate to our needs. Like Gassendi, Mersenne advocated mechanistic explanations in science, and following Galileo, he proposed mathematical models of material phenomena. Like the Epicureans, he believed that mechanism was adequate to save the phenomena. He thus rejected Aristotelian forms and occult powers. Mersenne was another of the great philosopher-priests of the seventeenth century who believed that to increase scientific knowledge is to know and serve God. See also DESCARTES, EPICUREANIS. R.A.W.
