Sohrab Ahmari's The Unbroken Thread: Discovering the Wisdom of Tradition in an Age of Chaos is the most recent entry into a genre that seeks to resolve contemporary problems by unearthing eternal truths from the Western canon. Notable prior efforts include David Brooks' The Road to Character and William J. Bennett's The Book of Virtues. I am not sure if this genre has a name, but I'll give it one: "McGuffey." I use this title because the genre is something of a reinvention of McGuffey Readers but for adults rather than 19th century American Protestant schoolchildren.
