Explains the logic of the book, how it is thematic, rather than
chronological, and attempts to explore the concept and practice of thrift
via influential characters and specific eras in which it has proved a
particularly potent concept. Sets up the difference between the early
meaning of thrift as thriving, and its later meaning of frugality. Briefly
explores the implications of this shift from ethical concerns about the
human condition, to more pragmatic concerns about human habits.
