I’m guessing that it’s a sort of "theory of “attribute evolution” and/or “attribute natural selection” that is necessarily necessary to athism?
No, your guess is wrong. Let me show you through a few examples (this will be long, please bear with me):
The different atoms all contain protons, electrons and neutrons. (Let’s forget about quarks and the rest). Different atoms have different numbers of these particles. Therefore different atoms have different attributes. In this case a quantitative difference results in a qualitative difference. In this case, the
whole is
not simply a mathematical sum of its
parts. Yet, no one attempts to invoke some “supernatural” reason for explanation - because it is not necessary. No one argues - at least to my knowledge - that the hydrogen atom is
both a physical entity (one proton and one electron)
and an immaterial “soul” - which is its “essence”.
When atoms form molecules, a whole lot of new
attributes “pop” up. Two hydrogen atoms, and one oxygen atom forms a water molecule. The attributes of water
cannot be reduced to the attributes of the constituent atoms. The whole again
is more than a simple mathematical sum of its parts. Yet, again, no one argues that the “wetness” of water needs a “supernatural” explanation. No one argues that the water molecule has an immaterial “soul”.
When water molecules are added up to form a greater mass, nothing special happens, we just get a large body of water. In this case the whole
is just the sum of its parts. On the other hand, if we pile up uranium atoms, and reach a critical mass, an explosion will happen. Up until that point, the whole is sum of its parts, but when adding the last atom the quantitative change will result in a qualitative difference. Yet, no one argues that some “supernatural” explanation is necessary.
Summary: These are just a few examples to show that the whole is sometimes just the sum of its parts, while other times it is not, it is more than just the sum of its parts. Hopefully, this is pretty obvious to all.
The critical point is that we do not need “supernatural” explanation for the water, even though the attributes of the water cannot be reduced to the atoms forming the water molecule. Yes, the water is just a bunch of atoms - in a very specific pattern, or arrangement, but the attributes of the water molecule cannot be explained by pure physics. We need chemistry to do that.
When considering carbon atoms, they can combine into different patterns. When the 6 carbon atoms form a planar structure, we get graphite. When the same 6 atoms reside at the vertices of an octahedron, we get diamond. The attributes of graphite are radically different from the attributes of diamond, even though they are both formed of the same carbon atoms - but their arrangement, their
pattern is different. (Yes, they both burn identically.) Yet, no one speaks of the different “souls” for graphite and for diamond.
STEM does not attempt to overlook the patterns of the physical objects. The arrangement itself is not a physical ontological object, it is the result (in the case of graphite - diamond) of the physical properties (the chemical bonds). The patterns or arrangements are all part of STEM.
Now, finally “life”. What is “life”? Biologists only have a working definition: “life is when the complex entity maintains its homeostasis in a changing environment”. Usually life is considered moving, growing, propagating its structure (multiplying). Yet, biologists cannot agree where to draw the line between “living” and “inanimate” matter. Some consider viruses as living entities, others do not. The point is that “life” is not a clear-cut matter.
The properties of life cannot be fully reduced to chemistry - just like chemistry cannot be fully reduced to physics. We need biology over chemistry. With complexity we get yet another level of emergent attributes. Yes, living material is fully composed of inanimate atoms (in a certain arrangement) but the attributes are life are more than just the sum of its parts.
When we accept that sometimes the whole is more than just the sum of its parts (atoms, molecules, etc.) - without invoking “supernatural” explanation for it, then there is no need to do this in the case of “life”. Sure “life” is highly complex, and we are far from understanding all its intricacies, but to invoke some “supernatural” stuff is to invoke the “God of the gaps”.
Intelligence, mind, concepts, emotions are all the results of the highest level of complexity in STEM - the human brain. (Yes, there can be more complex forms, we just don’t know about them.) It is much more than just the hodgepodge of atoms thrown together into a pile. How the brain works, we have only a very vague idea. But there is absolutely no indication that the mind is the product of an immaterial “soul”. When the parts of the brain get electrochemically excited, it will produce thoughts, emotions. When a part of the brain gets damaged, the mind gets “damaged”, too.
Conclusion: STEM is sufficient to explain everything there is. There is no need for the assumption of “souls”. The “whole” is sometimes more than just the sum of its parts. It does not mean that we must “reduce” everything to the dancing of the electrons. It cannot be done, but that is not a problem nor it is a surprise.
Well, that is it, folks. I hope some will take pains and read it.
