Perhaps the most intractable problem of all is not physical or even biological. It is existential. It concerns the status of meaning and value in a scientific universe. In Mind and Cosmos, Thomas Nagel argued that the prevailing materialist paradigm of reductive physicalism fails to account for the very capacities that make scientific understanding possible in the first place: consciousness, cognition, and the perception of value.
According to standard science, the universe consists of law-governed particles and fields, impersonal and indifferent. But we, who are made of those particles, find ourselves asking:
Why is there something it is like to be us?
Why do we experience the world as meaningful?
Why does reason track truth, and why does truth matter?
For Nagel, these are not “soft” philosophical distractions from the real business of physics – they are central features of reality. The emergence of consciousness, intentionality, and normativity cannot be explained by a worldview that treats only physical facts as ontologically fundamental. If value and meaning are real – if they exist – then they must be part of the natural order, not afterthoughts or illusions. The current scientific picture offers no place for such things. Evolutionary biology attempts to explain moral judgment and aesthetic feeling as adaptive functions; neuroscience reduces rationality to neural computation; cosmology regards the entire history of life and mind as a byproduct of blind initial conditions. In this view, truth, goodness, and beauty are accidents. As Nagel puts it: “It is difficult to make sense of the idea that life is something that could be fully understood by chemistry and physics alone.” This leads to an even deeper dilemma. If reason and value are not part of the fundamental structure of reality, why should we trust them at all? If our beliefs are shaped solely by selection pressures or physical law, what warrants our confidence that they correspond to truth, or that truth itself matters? If our cognitive faculties evolved for survival rather than truth, then their reliability becomes a matter of luck, which undermines the very possibility of scientific knowledge.
The problem of meaning and value thus undermines the coherence of the materialist framework from within. If we are the kinds of beings who can perceive meaning, recognise value, and pursue truth, then any complete account of the universe must include these capacities not as anomalies, but as central explanatory data. Nagel calls for a radical rethinking: a new conception of nature that integrates mind, value, and reason into its core ontology, rather than attempting to explain them away. Meaning, value, and reason are not detachable from consciousness; they are aspects of what consciousness does.
2PC rejects the assumption that meaning and value must emerge from an already fully realised physical universe. Instead, it proposes that meaning, valuation, and rational perspective are involved in the transition from possibility to actuality itself. Phase 1 is a timeless domain of physically consistent possibilities described by unitary evolution, which contains structure but no experience, perspective, or value. It is quantitative rather but not qualitative. Phase 2 is embodied reality: the experienced universe that becomes actual through collapse associated with conscious perspective. In this framework, meaning and value are not late evolutionary byproducts. They become operative at the Embodiment Threshold, where a self-referential system assigns incompatible valuations across possible states. Because physical dynamics alone cannot resolve normative conflict, collapse occurs as the resolution of representational incoherence within a unified subject. Valuation therefore functions as an ontological selector, stabilising one realised history from among many physically permitted alternatives without altering physical law.
This reframes Nagel’s concern about the reliability of reason. Rational cognition is not an accidental product of blind processes but a condition for stable embodied experience. Subjects persist only insofar as their representations maintain coherence across ongoing micro-collapses; truth-tracking cognition thus becomes structurally linked to the maintenance of reality as experienced. Meaning, in 2PC, arises from coherence within the continuous process of local collapse that constitutes consciousness. Symbolic systems — scientific, moral, or religious — do not disclose external purposes but constrain how coherence is achieved within consciousness–reality coupling in Phase 2.
