But if it’s emergent wouldn’t it also be fundamental? In the sense that its existence was inevitable. — invicta
Everything emergent is bound by fundamentality. All existants sit atop a universal "floor" - a singularity, or law or constant that dictates the potential to emerge into various things, behaviours and phenomenon. And this dicatation is reflected by the hierarchy of physical laws, principles and formulas, chemical bonding rules, types of bonds thus types of molecules, DNA etc - the instructions or dicatation is the relationships between the fundamental and its products - the emergents.
The laws and numerical values of physics are very specific and precise in a universe with complexity/ life. One doesnt require to "know" or "set up" physics beforehand, but merely needs run from potential through natural selection alone. As that in itself is an intelligent and logical process. Trial and error is a means of "perfecting" relationships in a cooperative/non contradicting or rational way, without self-violation, whilst always remaining dynamic, always changing/propagating further.
When an error occurs in the system, it is contradictory to what had previously become stable/set up, and thus is a "self violation" and leads to pause, cessation or decay of that particular pathway. But because change must continue, the system has no other option but to steer away from that error and towards another possibility, or begin another "trial" and hope this one is less erroneous/self violating.
That way logic can permeate through all processes. The system can be consistent and stable as it evolves.
You can imagine it like a tree that must grow outward without any if its branches blocking another or being blocked itself by a different branch. If a block occurs, the branch struggles, weakens or dies off or must alter course navigating elsewhere where it wont compete with ither factions.
In that way physics begins vague and with liberty in possible behaviours and relationships (the trunk of the tree) and emerges ever more specifically, complexly, restricted and defined as it branches upwards into chemistry, then biology and the kingdoms of life.
As for consciousnesses. There is human consciousness. There are other forms of consciousness also. What it is like to be complex and intelligent - aware of the external surrounding system, and a specific thing (agent) .
We usually associate consciousnesses with an "agent" - something small and objective with clear intent and behaviour, going about its business. So we associate consciousness as related to lifeforms. But how large and how complex must an agent be before we assign it consciousness? I think it is emergent from the get go. "God" or the universe, or whatever you want to call it, is a simple being, a singularity, whos intellect permits the logic, coherence, certainty, the stability necessary to establish memory, thus time perception, thus observation, thus knowledge of the system, thus control and behaviour, thus agency (self).
