Social Theory is more than a reader. Feminists, race theorists, decolonizing leaders, and others are thoughtfully introduced by Charles Lemert's substantial commentaries. Social Theory has always sought to keep up with the new while respecting the old-from Durkheim and Weber to Latinx and LGBTQ pioneers. When the book first appeared it was, as it remains, a collection of selections from those who have changed how we think about social things. Today, as the world is threatened by a global wave of anti-democratic movements, Social Theory adds a new early section to remind us of the origins of democratic values in the 1700s. A new concluding section focuses the theoretical mind on how, in the 2020s, social theorists are rethinking the world in order to better understand and resist the menace of anti-democratic movements.
