What do we mean when we say time passes? How do contingency and anachronism and other philosophical concepts bearing on time affect the more (seemingly) concrete realities of our political and cultural lives? In ways small and great, personal and cultural, we all experience the mutability of time. We feel it expand and contract, speed up and slow down, as it bends to the imperatives of memory, money, and the media. In our own time (itself a pregnant phrase) we have witnessed a disengagement with the past even as technological advances have allowed us to capture and reproduce past time as never before. How are we to make sense of this paradox?

In this wide-ranging meditation on the meaning of time, Sylvaine Agacinski weaves together discussions of Aristotle, Kant, Hegel, Freud, Heidegger, Baudelaire, Barthes, and especially Walter Benjamin -- her model for the modern "passer of time" -- as she traces a time line of the philosophy of time. After examining how shifting attitudes toward the passage of time have affected everything from art criticism to the development of photography to the rise of modernism itself, Agacinski concludes by proposing a rethinking of democracy that emphasizes patience in the face of our current temporal frenzy.

Sylviane Agacinski has never shied away from controversy. Vilified by some -- including many feminists -- and celebrated by others as a pioneer of gender equality, she has galvanized the French political scene. Her articulation of the theory of "parity" helped inspire a law that went into effect in May 2000 requiring the country's political parties to fill 50 percent of the candidacies in every race with women.

Sylviane Agacinski, according to "The New Yorker, " "is sometimes credited with making "parit?" respectable." Agacinski begins with the notion that sexual difference should be affirmed rather than denied. Sex, Agacinski points out, is not a social, cultural, or ethnic characteristic -- it is a universal human trait. In her argument for the necessary recognition of sexual difference, she enters into today's most controversial social territory.

Agacinski's model of parity does not strive for the nebulous ideal of "equality" between the sexes; instead, it demands a concrete formula for political contests: an equal number of female and male candidates in every election. It is a theory that has sparked impassioned debate across France: Are female politicians necessarily different from male politicians? Is parity democratic? Is it truly feminist?

Agacinski's sophisticated polemic will stimulate debate on American shores as it has in France. "Parity of the Sexes" sheds light on one of the crucial spheres of public life in which earlier French feminists left their work unfinished -- the realm of political power.
