I tend to look at existence as being an unavoidable continuum, counter to the popular scientific view that it must be quantum. Whether we're always open to appreciating the nature and source of it all or not. Pattee, Elsasser, Slobodkin, Dyson and others too, inquired to resolve the question. There is no singular voice which can claim sole insight or expressiveness about it, but maybe this short piece by Buckminster Fuller says it in a deep and heart-known way, even as I've tried to describe the techniques. Open to other views.
Nobody is born a specialist.
Every child is born with comprehensive interest, asking the most comprehensively logical and relevant questions. The Earth revolves as the radiation from the Sun's flame reaches the revolving Earth. By photosynthesis the green buds and leaves of the tree convert the Sun radiation into hydrocarbon molecules, which form into the bio-cells of the green, outer, cambium layer of the tree. When the log pop-sparks, it is letting go a very sunny day long ago, and doing so in a hurry. Conventually educated grown-ups rarely know how to answer such questions.
