Abstract

Margaret Cavendish was a contemporary critic of the mechanistic theories of matter that came to dominate seventeenth-century thought and the proponent of a distinctive form of non-mechanistic materialism. Colour was a central issue both to the mechanistic theories of matter that Cavendish opposed and to the non-mechanistic alternative that she defended. This chapter considers the form of colour realism that Cavendish developed to complement her non-mechanistic materialism, and uses her criticisms of contemporary views of colour to try to better understand the experimental approach to natural philosophy associated with writers like Hooke and Boyle. Allen argues that Cavendish’s discussion of colour in Observations upon Experimental Philosophy helps to show that there was a close connection between experimental philosophy and mechanistic theories of matter, and that, at least in the middle of the seventeenth century, experimental and speculative forms of mechanism were not mutually exclusive.
