Authors William Strauss and Neil Howe introduced a popular theory in their book, The Fourth Turning, outlining the recurring generational cycles that have occurred throughout American history.

What are your thoughts?

Doug Casey: I read Strauss and Howe's first book, Generations, when it came out back in 1992. I thought it was brilliant.

Let me start off by recommending both Generations and The Fourth Turning to everybody. Both books offer quite a scholarly, readable, and prescient view of the cyclicality of history. And offer a very plausible forecast for the 2020s.
