Women's Lives, Men's Laws contains the deepest and best feminist writing around, and there is nothing like it. MacKinnon is a figure of singular importance for the history of feminist thought and for its present. Before MacKinnon, there was no legally usable concept of sexual harassment. Now in any law library there are shelves of publications developing her ideas. Before her work, sexual advances in the workplace were not typically seen to involve an asymmetry of power (although they always did involve this, and women knew it). Now even the most conservative judge will use MacKinnon's framework of analysis in adjudicating cases. Before MacKinnon, again, issues of sexual equality were commonly dealt with by saying "equals to equals, unequals to unequals" - so if a difference could be shown between women and men, for example that only women get pregnant, not providing employees with pregnancy insurance did not constitute sex discrimination. After MacKinnon the concept of equality was understood in terms of a different antonym - subordination, second-class citizenship. Before MacKinnon, the law of obscenity focused on the alleged offensiveness of the sexy. Now even those who do not agree with her practical proposals agree that issues of violence, subordination, and abuse must be central in coming to grips with the problem of pornography. Finally, it is to a considerable extent due to MacKinnon's influence that sexual abuse of women is now regarded as a major human rights violation internationally. In short, as even critics of her views will readily agree, there is no single person who has done more to change the course of American law. She is among the century's most important thinkers, and I can think of none whose theoretical work has done more to improve human well being.

The writings in MacKinnon's Women's Lives, Men's Laws continue to be excellent - fresh, concise and incisive. She has new things to say that will continue to enrapture and enlighten a large readership (and perhaps enrage others, many of whom perhaps never actually read her work).
