Hi Joe,
I still have not gotten to your essay, but your comments on my page prompt me to say more here. I acknowledge and agree with your uniqueness principle, insofar as we are talking about life in the world made of protons, neutrons, and electrons - the same basic stuff we are made of. While we may call other kinds exotic matter, to some extent 'normal' fermionic matter is more 'exotic' when considering the whole of the universe, as Physics now understands it.
But uniqueness and oneness are not the only archetypes that matter. I would say that uniqueness is absolutely necessary, and it is of course uniquely powerful among all the archetypes of form, but it does not tell the whole story - maybe something important that is often overlooked, but not everything. If we allow that in addition to uniqueness, completeness, nothingness, and enoughness or sufficiency are preserved, we can build a conceptual hierarchy to hold the fundamental forces of Physics. See my essay, from an earlier contest
In relation to this contest; it is especially important to see the role of a fifth quality or archetype which we can call agreement or equality, because this property is what maps information to form, or vice versa. I'm just observing that your main point is sort of like saying we can learn everything about Physics by studying Gravitation. Now if we really deeply understood Gravity, a lot of Physics we don't understand might fall into place, but studying the other forces is hardly a waste of time.
That's all for now, but I will comment once I get to read your essay.
All the Best,
Jonathan
