On a final note on emergence and/or self organisation, it is evident that there are many mysterious phenomena in nature that are not explained by conventional scientific understanding as we know it.
Examples would be how termites make and repair their mounds, how pigeons home, how birds change direction in a murmuration with no apparent lead bird, even how dogs find their way home.
Have a look at the video in the murmuration link. What, we wonder, is the purpose of the display? Is it for fun? Is it to practice avoiding predators? Whatever its purpose, it is certainly wonderful to behold! And why is it wonderful? Where does wonder come from?
Some scientists believe that there are forces, fields, phenomena as yet unexplained at work in such cases.
The scientist Rupert Sheldrake has called these forces morphic fields. His theories speculate that the fields that enable self-organisation evolve in sympathy with the influence of like upon like through space and time.
Nobody has the plan, really, for an oak tree, an anthill or a family. They simply grow, organise themselves and emerge!
