There is no master plan. We do it ourselves. Conversely, evolution does not happen by random chance, by stupid mutations. God is not playing dice with the Universe, but we do make a good deal of it up as we go along. It does not happen to us.
Self organization develops without predetermination.
There is free will. Still, there are constraints. The self organization is structured and shaped by basic laws. As shown in the prior chapters it is shaped by the four dimensions and other numerical building blocks of nature. As we have seen the key to this process is spontaneous improvisation in the moment.
