Decline of civic life

The Boston Public Library, 700 Boylston St., will welcome author Eric Klinenberg from 6 to 7:30 p.m. on Monday, Sept. 17.

Americans are sorting themselves along racial, religious and cultural lines, leading to a level of polarization that the country hasn’t seen since the Civil War.

In his new book “Palaces for the People: How Social Infrastructure Can Help Fight Inequality, Polarization and the Decline of Civic Life,” Klinenberg posits that the future of democratic societies rests not simply on shared values but on shared spaces: the libraries, childcare centers, bookstores, churches, synagogues and parks where crucial and sometimes life-saving connections are formed. These are places where people gather and linger, making friends across group lines and strengthening the entire community.

Admission to this talk is free.

Call 617-536-5400 for more information.

Celebrating Alcott

Dr. Elif Armbruster will be the guest speaker at a free program from 6 to 7:30 p.m. on Tuesday, Sept. 18 at the Boston Public Library, 700 Boylston St., celebrating the 150th anniversary of the publication of “Little Women.”

In her talk, Armbruster revisits “Little Women” from the perspective of 2018 and contemplates seeing at least one of the book’s heroines—Jo March—not as a “little woman,” but as a “nasty” one.

Armbruster is an associate professor of English at Suffolk University where she teaches courses in American Literature, American Studies, and Women and Gender Studies. In addition to her book, “Domestic Biographies: At Home with Stowe, Howells, James and Wharton,” she has forthcoming essays on Willa Cather, Laura Ingalls Wilder and Harriet Beecher Stowe.
