The almost ugly, almost reptilian, and at the same time almost amphibian looking Yoda was a Jedi Master, a source of wisdom for bringing down the evil empire, and masterfully fought for good.
On a somewhat similar note, there is an astounding ability in a tiny, some would say ugly, creature that is worth noting:
The newt can reconstruct almost any body part, including the brain, spinal cord, heart and limbs. Planarians, a high-school laboratory favorite, can be sliced to bits and each piece will regenerate a new individual.(The Scientist). The biological ability to morph back into what one was before being severely damaged is notable to say the least, and adds a new dimension to "physician heal thyself".
It stands out as very hip or evolved, especially remembering all of the national hoopla and debate about stem cells and stem cell research.
It seems that every cell in some creatures is like a stem cell, because when damaged, legs, tails, eyes, and even the brain can be reconstructed by these "lowly creatures".
Try walking into your super-duper best in the world realm of the robe wearers at your local hospital and have them grow you back a leg, eye, brain, or arm. Not gonna happen.
Trillions upon trillions of dollars in fantastic equipment and millions of hours of university study, yet the medical robe wearers can't do what the lowly newt can do. The fictional Yoda was spot on when he said:
Size matters not. Look at me. Judge me by my size, do you? Hmm? Hmm. And well you should not. For my ally is the Force, and a powerful ally it is. Life creates it, makes it grow. Its energy surrounds us and binds us. Luminous beings are we, not this crude matter. You must feel the Force around you; here, between you, me, the tree, the rock, everywhere, yes. Even between the land and the ship.(Yoda Quotes). The Star Wars writers gave fictional life to what scientists who labor in the field of biomimicry know: the sum of wisdom and knowledge is not stored in the human species; so they artistically created the notion of The Force as the repository of that special something.
So, Tenet Four advocates learning from any and all of the creatures of the earth, including microbes, based upon the hypothesis that wisdom and knowledge is hidden down deep in these creatures.
Wisdom that may help pass The Test if we can only learn first to value our home: the earth's ecosystem.
