It is a cliche that not knowing history makes one repeat it. As many people have also pointed out, the only thing we learn from history is that we rarely learn anything from history. People engage in land wars in Asia over and over. They repeat the same dating mistakes, again and again. But why does this happen? And will technology put an end to it?
One issue is forgetfulness and “myopia”: we do not see how past events are relevant to current ones, overlooking the unfolding pattern. Napoleon ought to have noticed the similarities between his march on Moscow and the Swedish king Charles XII’s failed attempt to do likewise roughly a century before him.
