Since this interview was recorded in 1967, and they are talking about his latest book, I suspect they are referring to ‘The temper of our time’. But, this excerpt comes from “Eric Hoffer: The Passionate State of Mind” with Eric Sevareid, CBS, September 19, 1967 (rebroadcast on November 14, due to popular demand). So, that could be the book they are referring to, though it was written much earlier.
Here is the list of his books:
1951 The True Believer: Thoughts On The Nature of Mass Movements ISBN 0-06-050591-5
1955 The Passionate State of Mind, and Other Aphorisms ISBN 1-933435-09-7
