Book excerpt: The first edition of A Contemporary Introduction to Sociology was the first truly new introductory sociology textbook in decades. Written by two leading sociologists at the cutting edge of theory and research, the text reflected the idioms and interests of contemporary American life and global social issues. The second edition continues to invite students to reflect upon their lives within the context of the combustible leap from modern to postmodern life. The authors show how culture is central to understanding many world problems as they challenge readers to confront the risks and potentialities of a postmodern era in which the futures of both the physical and social environment seem uncertain. As culture rapidly changes in the 21st century, the authors have broadened their analysis to cover developments in social media and new data on gender and transgender issues.
