Johannes Kepler on whether his wife Susanna Reuttinger was destined as "The One":

Though all Christians … declar[e] solemnly that they enter into married life owing to a special divine management, ….

Was it divine Providence or moral guilt on my part which has torn my mind … in so many different directions and which led me listen to so many people … so divergent from each other?

Was it divine management that brought in all these persons and their actions?

As I believe, nothing extraordinary has happened to me. I believe that everyone of us has an experience similar to mine, not only once but very often. The difference is only that the others do not worry about it, as I do, they forget more easily and get over it more quickly than I do, or that they have more self-control and settle their unhappiness by themselves.

There is something wrong with my feelings; I stirred them up anew every day ….

As far as [Susanna] is concerned there is still the question of why, though she was destined for me, G-d permitted that she had six rivals in the course of one year?

Check out this portrayal of the computer from 1978.

  • Same concerns about privacy.
  • Same awe at its power (although the reel decks aren’t probably so familiar to most people anymore).
  • And computers, although they run a lot of stuff, like air control and banks, don’t show up much in your & my day-to-day lives, at least not obviously.
