A groundbreaking exploration of the ancient rules women unwittingly follow in order to be considered "good," revealing how the Seven Deadly Sins still control and distort their lives and illuminating a path toward a more balanced, spiritually complete way to live Women congratulate themselves when they resist the doughnut in the office break-room. They celebrate their restraint when they hold back from sending an e-mail in anger. They feel virtuous when they wake up at dawn to get a jump on the day. They put others' needs ahead of their own and believe this makes them exemplary. In On Our Best Behavior, journalist Elise Loehnen explains that these impulses--often lauded as unselfish, distinctly feminine instincts--are actually ingrained in women by a culture that reaps the benefits, via an extraordinarily effective collection of mores known as the Seven Deadly Sins. Since being codified by the Christian church in the fourth century, the Seven Deadly Sins--pride, greed, lust, envy, gluttony, wrath, and sloth--have exerted insidious power. Even today, in our largely secular, patriarchal society, they continue to circumscribe women's behavior. For example, seeing sloth as sinful leads women to deny themselves rest; a fear of gluttony drives them to ignore their appetites; and an aversion to greed prevents them from negotiating for themselves and contributes to the 55 percent gender wealth gap. Loehnen reveals how women have been programmed to obey the rules represented by these sins and how doing so qualifies them as "good." This probing analysis of contemporary culture and thoroughly researched history explains how women have internalized the patriarchy, and how they unwittingly reinforce it. By sharing her own story and the spiritual wisdom of other traditions, Loehnen shows how women can break free and discover the integrity and wholeness they seek.
