This paper explores an overlooked aspect of the brief but intense correspondence between William Petty and Henry More, making use of the Hartlib Papers Online. Traditionally, the brief epistolary exchange between More and Petty has been seen in the light of an opposition between Cartesian rationalism and Baconian empiricism. A look at the original manuscripts, however, shows that the opposition was not originally framed in those terms at all. This article draws attention to the actors’ original categories, and places this exchange in the evolving landscape of seventeenth-century natural philosophy.
