The Four Axioms
I am, and I observe.
I cannot define consciousness, but my genome seems to encode the instructions to generate it.
The four presented axioms are based on observations, and as such cannot be proven. However, the observational evidence suggesting they hold is strong.
Given DNA
The human organism
The physical processes underlying DNA and the human organism fall within the computable. A sufficiently powerful computing system can, in principle, simulate them to arbitrary precision:
This is a weaker claim than the full Church-Turing thesis: we require only that the specific class of processes DNA relies on is computable, not that all physical processes are. Rejecting this axiom requires identifying a property in DNA that requires infinite precision, for which no evidence exists. Also, we require only precision sufficient to make biological processes to run duplicate the structure of human.
Subjective experience is not epiphenomenal. A human with subjective
experience
Under the framework of Axioms 1–4, we formulate two thought experiments to prove that physical reality is inherently timeless and substrate-independent. Furthermore, we establish that the internal observer
Consider a digitized human DNA, and a simulation of it running on a computer.
If consciousness is produced by human DNA, it must also be produced by an
identical digital simulation. Both entities share the same axiomatic structure;
just as the equation
The simulation consists of code (the laws of physics as implemented) and data (the state of the
simulated universe at each timestep). Denote the running simulation
Now optimise the simulation code progressively by introducing lookup tables: replace
computed transitions with precomputed results. At each step, the external
runtime decreases while the internal state sequence --- the ordered record of
Alice's experiences, perceptions, and actions --- remains identical. Carry
this optimisation to completion, replacing all computation with a static,
precomputed dataset
Let
In the limit
Suppose it does not. Then there exists a minimum code-to-data ratio below
which consciousness ceases. This minimum ratio is a new physical constant:
a threshold property of information processing not derivable from
Conclusion 1. Consciousness is an emergent property of the information structure of the execution trace, not of the process that generates it. A static bitstring encoding a conscious observer's state sequence contains that observer's conscious experience. Subjective experience and time emerge solely from the internal structure of information.
Conclusion 2. The optimization argument yields a family of distinct execution
traces
Consider a computer running DNA simulation of Alice. If the software program consisting
of vast number of CPU instructions producing the execution trace that describe Alice,
then what does a one minimal CPU instruction causing one bit to flip define?
Consider one such discrete change in the state of the computer.
That should map to corresponding change in the virtual Alice.
Call the first
Causation, on any account, requires an orderable relationship between cause
and effect:
No such ordering is available even in principle. Each domain has its own internal ordering — the sequence of physical ticks, the sequence of Alice's experienced states — but internal ordering within a domain is not an ordering between domains. There is no clock common to both domains, and positing one would be positing exactly the new physical (or meta-physical) fact Axiom 2 excludes.
Conclusion 3. A relationship that admits no before, after, or simultaneous-with cannot be a causal relationship, regardless of how consistently its two sides co-occur. The computer and Alice's experience therefore stand in a representational relationship — two arrangements of the same information — not a causal one.
Consider a multi-threaded computer running two DNA simulations concurrently:
Does Alice's consciousness depend on the contiguity of her bits in this
external trace? Suppose it does. Then there exists a minimum bit-contiguity
or thread-density threshold required for consciousness. This threshold is
again a new physical constant not derivable from
Conclusion 4. Conscious experience cannot depend on the contiguity, order
or density of its encoding in any external execution trace. A bitstring of length
Conclusions 1 -4 together establish the central result of this paper.
Substrate Independence. Consciousness is a property described by certain finite information structures. The physical substrate in which such a structure is instantiated --- silicon, neurons, magnetic domains, or static bitstring --- does not determine whether the structure describes consciousness. A computer running a simulation of a conscious observer and the simulation itself are two arrangements of the same information. Neither is causally prior to the other. Neither is more fundamental.

Therefore
This result, combined with the substrate independence established entails the full Internal Emergence Principle: consciousness is a property of certain finite information structures, and any configuration space large enough to contain such structures contains consciousness, with no running process or external reader required.
Let
This corollary makes precise what "sufficient fidelity" means for a
conscious simulation. It does not require perfect simulation of all physical
processes, only those that DNA-based processes depends on. The
threshold
The foundational falsifiability criterion of this paper is long-term: if a
sufficiently accurate DNA simulation --- one satisfying
A nearer-term criterion follows from Axiom~3: if a physical process essential to DNA function is shown to be provably non-computable, the framework fails. This is in principle testable through precision studies of quantum coherence in biological systems.
From the optimization thought experiment it follows that different implementations (execution traces) implement identical simulation (Alice). Individual bit-patterns are not significant - Alice is an equivalence class in that many different bit patterns describe the same Alice.
Because there is no causal relationship but representational, running a DNA simulation multiple times does not create multiple instances of Alice; rather, it traces out (discovers) different representations of the same "Alice" equivalence class. Computers do not create new information.
Axiom~3 does not restrict to classical computation. The computability claim covers any physically realisable process, including quantum processes. Quantum computation is an alternative physical realisation of the same formal state-transition structure and is therefore covered by the axiom without requiring a separate argument. Substrate independence follows for quantum computers by the same derivation as for classical ones.
The substrate independence established in this paper has an immediate and non-trivial consequence for the study of physical phenomena.
Because a physical system and its computational simulation represent equivalent configurations of information, the execution trace of the simulation necessarily preserves the properties of the physical system. Consequently, despite our internal vantage point within the universe, analyzing physical phenomena through a computational framework allows us to study reality as an information processing system.
We have established four axioms and derived from them the following results.
-
Time as Internal Ordinal. Time is not a fundamental external parameter but an internal ordering relation emergent from the observer's information structure. The universe, at the level of the totality, is static and timeless. What observers experience as the flow of time is the traversal of an internally ordered sequence of states encoded in a static information structure.
-
Finiteness. The simulation computer is a discrete, finite system, so the execution trace is a finite bitstring. The universe it represents is therefore characterised by a finite bit count
$n$ . -
Substrate Independence. Consciousness is a property described by certain finite information structures. The physical substrate in which such a structure is instantiated does not determine whether it is conscious. A computer running a simulation of a conscious observer and the simulation itself are two arrangements of the same information, with neither causally prior to the other.
Representational Relationship. A physical computer running a DNA simulation and the simulated conscious agent itself stand in a relation of informational equivalence rather than causation. The physical computer does not generate the simulated agent; rather, its execution trace merely traces a representation of a pre-existing informational structure for external observers. The simulated entity exists independently of execution.
-
Simulated Conscious Observer. A simulation physically and behaviourally indistinguishable from a conscious observer must itself instantiate subjective experience. Two identical axiomatic systems must behave identically.
-
Causal Efficacy of Qualia. Subjective experience is not epiphenomenal. It is a causally distinguishable component of the observer system.
-
Representational Equivalence as a Physical Tool. The equivalence of geometric and computational descriptions licenses the use of the execution trace as a faithful proxy for physical processes that are geometrically inaccessible.
By treating subjective experience as a causally efficacious property of a computable information structure, the framework moves from metaphysical speculation to a derivation with testable consequences. The foundational falsifiability criterion is the construction of a behaviourally indistinguishable DNA simulation that lacks subjective experience.
