Through luminous and erudite readings of the texts, Hasana Sharp shows us how profound and radical is Spinoza's conception of nature and his claim that humans always remain part of nature, acting solely according to the same rules. She demonstrates the political consequences of adopting this perspective through a provocative intervention in contemporary feminist theory, while along the way opening promising avenues for future work in a variety of other fields, such as animal studies and ecology. This is a challenging and important book.
