Between 1653 and 1655 Margaret Cavendish makes a radical transition in her theory of matter, rejecting her earlier atomism in favour of an infinitely-extended and infinitely-divisible material plenum, with matter being ubiquitously self-moving, sensing, and rational. It is unclear, however, if Cavendish can actually dispense of atomism. One of her arguments against atomism, for example, depends upon the created world being harmonious and orderly, a premise Cavendish herself repeatedly undermines by noting nature’s many disorders. I argue that her supposed difficulties with atomism expose a deeper tension in her work between two fundamental metaphysical commitments each of which has substantial philosophical support: her monist theory of the material world (which maintains that there exists just one natural substance which is the single principal cause) and her occasional theory of causation (which requires multiple finite principal causes in nature -- causes that might be considered individual substances). Her monism undermines atomism while her theory of occasional cause seems to rest on a conception of nature that would be especially friendly to atomism. I argue further that we can solve this tension within a Cavendishian framework in such a way as to preserve her theory of causation and her monism, but that this solution depends upon our taking her monism in a particular (and weak) form. I finally note that we can best make sense of her unique and interesting form of monism by acknowledging her social-political motivations in addition to her motivations in natural philosophy.

Descartes' Meditations, one of the most influential works in western philosophy, continues to provoke discussion and debate. This volume of original essays by leading established and emerging early modern scholars ranges over all six of the Meditations and explores issues such as scepticism, judgement, causation, the nature of meditation and the meditator's relation to God, the nature of personhood, Descartes' theory of sense perception and his ideas on the nature of substance. The contributors bring new insights to both central and less-studied topics in the Meditations, and connect the work with the rich historical and intellectual context in which Descartes forged his thought. The resulting volume will appeal to a wide range of scholars of early modern thought.
