‘Learning From History’: A Goal? A Delusion? A Trap?

‘Learning From History’: A Goal? A Delusion? A Trap?

Last week, as part of The Atlantic’s discussion of the 15th anniversary of the disastrous invasion of Iraq, I wrote a post called “The Inevitability of Ignorance.” Its main point was about the necessity, and the impossibility, of trying to “learn” from successes and failures in the past.

Everyone has heard the Santayana chestnut/homily/warning about “those who cannot remember the past….” But even the most earnest efforts to apply yesterday’s lessons can cause missteps across tomorrow’s terrain, with its inevitable surprises and differences.

As a tool in managing this contradiction, I also mentioned the insightful book by Ernest May and Richard Neustadt, Thinking in Time, which is about the difficulty and utility of looking for historic patterns and clues.

Now, several readers weigh in—on the specific failures born of amnesia I mentioned, Lyndon Johnson’s escalation in Vietnam and George W. Bush’s decision to invade Iraq, and on the larger struggle to “learn” from the past only to the right degree.
