 Cavendish’s philosophical work was not taken very seriously in the seventeenth century, but it is certainly relevant today. She is presumably right to warn about the inconsistency in insisting that God is utterly transcendent while being utterly confident in putting forward claims about His nature. She has also anticipated a contemporary emphasis on the study of the brain and body in addressing mental health. In addition, she has made a contribution to the current debate about how to understand the relation between the most basic elements of body and the mental activity that is manifested in human beings and other organisms (Strawson 2008; McGinn 1999, 6–18; Chalmers 1996, 3–6; and Nagel 1974, 435–450). She is also important insofar as she anticipates the arguments and views of early modern thinkers who are firmly in the canon and who already secure a great deal of attention. Finally, she offers extremely compelling insights into issues of agency and authority. She argues that one of the reasons why an individual is often unsuccessful in embodying a life with which they identify is that, even if everything is in order on the side of their decisions and talents and skills, there is often social and political corrosion in the interface between their decisions and the world.
