planetary system is
in any way connected to a millennia - old book of fairy tales.

in which it has its root, yet distinguished from it by an autonomous circulatory, nervous and, finally, cerebral
system.
And what can this mean except that, like those
planetary orbits which seem to traverse our solar
system without remaining within it, the curve of consciousness, pursuing its course of growing complexity, will break through the material framework of Time and Space to escape somewhere towards an ultra-center of unification and wholeness, where there will finally be assembled, and
in detail, everything that is irreplaceable and incommunicable
in the world.
At the very time we humans have been learning more about the ecology of all
planetary life, we have been discovering to our horror how much we are now upsetting the delicate balances
in the living
systems of the ecosphere.
Asserting that
in our time the whole
planetary system must be taken into account
in planning for a humanly desirable future, he argues that the prime end must be to redirect the use of human and technological resources to overcoming the gap between the affluent nations and that much larger portion of mankind which still exists
in hunger, poverty, disease, and misery.
Within the continuum of
planetary life there have evolved many interconnected
systems, each of them
in symbiotic relationship with its environment.
We need not anthropocentrically imagine the evolutionary process to culminate
in man, for it is quite conceivable that
in time it might bypass man and the entire class of mammals to favor some very different species capable of a greater complexity than man can achieve; if not here on earth, then
in some other
planetary system.
This process is called accretion, and you can see it at work over and over again
in real life as we currently can watch other new (
planetary systems) forming

In his infinite wisdom, he has created such intricately complex, and self sustaining living beings, and
planetary systems that could not (even by any strech of imagination or clever postulation) be honestly construed to be an accident.
The history of science provides many examples of this combination of analogy and innovation
in the creation of models which were useful
in generating theories.4 The «Bohr model» of the atom,
in which «
planetary» electrons revolve
in orbits around a central nucleus, resembles the solar
system in certain of its dynamical properties; but the key assumption of quantum jumps between orbits had no classical parallel at all.
