The human quest for perfection & truth.
In Greek times it is said that people still lived in touch with the (heavens) above, here on this its imperfect mirror image on earth.
Plato said:"Look to the perfection of the heavens for truth", while Aristotle said: "look around you at what is, if you would know the truth"
Aristotle thus separates heaven & earth, making only what you see, the visible, real or truth.
Aristotle sets out the nature of man through the ages, to the present day. Now one could argue the above or heaven does not EXIST, therefore only the earth & matter is reality. For even when we look at the skies at night we are looking at matter for truth, not at Plato's above.
Increasingly it seems the hindu concept of "Maya" or the illusion of reality, matter and our lower self has imposed itself as the only probable (proveable?) fact or truth, over and 'above' the underlying reality or that which really moves us, Spirit and our higher selves.
Motion is the interaction between Spirit & Matter. Human emotion and the living experience, its "animate" manifestation.
