I disagree strongly with the reviewer who posted before me. The reviewer criticizes Irigaray for being an idealist-- but idealism is important, because it is what allows us to imagine a future where our lives are happier and the world is more just. Plus, this book is full of practical ways in which to think about implementing that vision-- like a discussion of what kind of laws the European Union would need if it really wanted to treat women as though they were equal to men.
This book argues that if we want gender equality, then we need to do some serious thinking about some fundamental philosophical concepts we have, rights foremost among them. And it shows that we can't have gender equality if the yardstick for that equality is always the male one.
