I used to consider my knowledge of history better than at least 95% of the population, but while reading The Decline and Fall of the Roman Empire I realized how sketchy my view of history really was. So at the ripe old age of 35 I set off on a course of study centered on two series of books, The Story of Civilization, by Will and Ariel Durant, and Timeframe, a Time-Life series focusing on a timeframe in human history and what was going on in all parts of the world inhabited by man: lots of pictures and of course superficial, but it painted in a lot of gaps I othewise would have never covered. The Timeframe series starts much earlier than the Durant's, but once both series were in sync I would read the books in both series for an epoch, as well as at least two other books, either written in the era or about the era, drawing mostly from science, culture, and biography. For instance I read all the books of Euclid, Newton's Optiks and Principia (I slogged through the Motte transaltion before the first modern English translation became available), The Wealth of Nations, Shelby Foote's 3-volume history of the Civil War, and The Origen of Species. (It's real easy for me to spot folks who spoot-off about Wealth or Origen who have not actually read the books.) My program culminated with Tragedy and Hope, which being such an inflammatory work, I did not trust to read without the full background of history. The process was like watching Western Civilization unfolding.
Now for the unintended consequences: I became a bore at cocktail parties. I wanted to talk about the ideas in the fascinating book I was reading. I used to love arguing politics. Even with my prior knowledge it was hard enough finding opponents who would engage in rational discourse, now it is impossible. It's been so long my debating skills have totally gone down the tubes. The sad thing is I believe my problem is really society's. Political correctness (among other problems) in academia, has produced a generation of intellectually crippled intellectuals; and the entertainment industry, including the 24-hour news cycle as entertainment, has just stupefied people. I fear for democracy and republican government.
