Extinction is the rule. Survival is the exception.
One of the questions asked by al-Balkhi, and often repeated to this day, is this: Why do the children of Israel continue to suffer? My grandmother Dodo thought it was because the were jealous. The seder for Passover (which is a shame-faced simulacrum of a Hellenic question-and-answer session, even including the wine) tells the children that it's one of those things that happens to every Jewish generation. After the or or Holocaust, many rabbis tried to tell the survivors that the immolation had been a punishment for 'exile,' or for insufficient attention to the Covenant. This explanation was something of a flop with those whose parents or children had been the raw material for the 'proof,' so for a time the professional interpreters of god's will went decently quiet. This interval of ambivalence lasted until the war of 1967, when it was announced that the divine purpose could be discerned after all. How wrong, how foolish, to have announced its discovery prematurely! The exile and the Shoah could now both be understood, as part of a heavenly if somewhat roundabout scheme to recover the Western Wall in Jerusalem and other pieces of biblically mandated real estate.I regard it as a matter of self-respect to spit in public on rationalizations of this kind. (They are almost as repellent, in their combination of arrogance, masochism, and affected false modesty, as Edith Stein's 'offer' of her life to expiate the regrettable unbelief in Jesus of her former fellow Jews.) The sage Jews are those who have put religion behind them and become in so many societies the leaven of the secular and the atheist.
If you were designing the sort of information-processing system a brain is, it would be extremely impractical to store memories permanently in their original form. You need mechanisms for transforming and recording them; for chunking information into categories . Is your memory a phonograph record on which the information is stored in localized grooves to be replayed on demand? Is so, it's a very bizarre record, for the songs are different every time they're played. Human memory is more like the village storyteller; it doesn't passively store facts but weaves them into a good (coherent, plausible) story, which is recreated with each telling.
