In Wittgenstein, Tanesini offers a highly original interpretation of several themes in Wittgenstein's philosophy. She argues that when we look at his work through feminist eyes we discover that he is not primarily concerned with providing solutions to technical problems in the philosophy of mind, mathematics, and language. Instead, his remarks on these topics are intended to offer insights about human finitude, the loneliness of the modern autonomous self, and our relations to other human beings. Thus, the modern conception of the individual emerges as the critical target of Wittgenstein's philosophical work, both early and late.

This conception has also been one of the dominant concerns of contemporary feminist philosophy. In this book, Wittgenstein's insights are deployed to further feminist debates on issues such as identity, difference, the masculine character of the modern self.
