What the literature leaves open

  • The need to reconcile the subjective, qualitative nature of experience with the objective, quantitative methods of scientific inquiry.

    Editorial: The end of qualia. Do we still need phenomenology in the science of consciousness? · 2026 · DOI

  • The study argues that the concept of qualia may have constrained the ways in which the problem of conscious experience can be investigated. The paper highlights the need for alternative approaches to understanding conscious experience, beyond the traditional framework of qualia and physicalism.

    Editorial: The end of qualia. Do we still need phenomenology in the science of consciousness? · 2026 · DOI

  • Applications to further domains are also sketched, and a number of open problems outlined.

    A Chancy Theory of Metaphysical Indeterminacy · 2026 · DOI

  • Yet it remains unclear how to account for the perceptual phenomenology of language experience.

    Language comprehension and the rhythm of perception · 2025 · DOI

  • The gap between the Theory of Objectivity and its critics, such as van Hamme, is the question of whether the theory fully demonstrates the transition to the effective articulation of reality. The gap between the theory's claim to provide a logical-ontological grounding of the universe and its actual ability to do so.

    THE MODAL DISCIPLINE OF ONTOLOGICAL FUNDAMENTALITY: a critical–propositional analysis of On Modal Discipline and Ontological Fundamentality: Admissibility, Articulation, and the Scope of the Theory of Objectivity (V 1.0), by Carlos van Hamme, in confrontation with the Theory of Objectivity · 2026 · DOI

  • The need for a theory of fundamentality in general and categorial fundamentality in particular. The lack of a clear understanding of what it means for natural kinds to be fundamental.

    Natural kind fundamentalism · 2026 · DOI

  • Future research could explore the ontological foundation of the description of reality in relativistic physics. Future research could examine the implications of the Theory of Objectivity for the description of reality in relativistic physics.

    THE MODAL DISCIPLINE OF THE INVERSE TRANSFORMATION OF RINDLER SPACETIME: A critical–propositional analysis of Inverse-transformation of 4-dimensional Rindler spacetime, by Sangwha-Yi, in confrontation with the Theory of Objectivity · 2026 · DOI

  • The manuscript's reduction of reality to its formal structure of recursive compression is a gap. The absence of a robust theory of reciprocal observability is a gap.

    SINGULAR DUALITY AND THE MODAL DISCIPLINE OF OBJECTIVITY A critical–propositional reading of the manuscript A Singular Duality: A Unified Framework Proving Our Mathematical Universe, by C. Mike "WildFacts" Rubendall, in confrontation with the Theory of Objectivity · 2026 · DOI

  • Future research should focus on developing a logical demonstration for RCC's foundational principles. The development of a modal ontology for RCC could address the problem of foundation. Further research is needed to fully explore the implications of RCC's propositions for cosmology.

    RUPTURE–CONTAINMENT COSMOLOGY: a critical–propositional reading in light of the Theory of Objectivity · 2026 · DOI

  • The gap is RCC's failure to provide a logical demonstration for its foundational principles. RCC displaces the problem of foundation without resolving it. The gap is the lack of a modal demonstration for the necessity of rupture in RCC.

    RUPTURE–CONTAINMENT COSMOLOGY: a critical–propositional reading in light of the Theory of Objectivity · 2026 · DOI

  • The paper argues that the extensional model of temporal awareness has faced mounting critique and needs to be defended.

    From the Agent’s Perspective: Action and the Temporality of Experience · 2026 · DOI

  • The gap in current approaches is the assumption that concepts are individuated by their semantic content.

    Conceptual Engineering: Discontinuity and Individuation · 2026 · DOI

  • Future research could explore the implications of idealization of memory for epistemic two-dimensionalism. Future research could also examine the relation between Frege's puzzle and other theories in the philosophy of language.

    Memory, idealization, and Frege’s puzzle · 2026 · DOI

  • The paper argues that idealization of memory is a key aspect of epistemic two-dimensionalism that has not been fully explored.

    Memory, idealization, and Frege’s puzzle · 2026 · DOI

  • The paper identifies a gap in understanding how truth, sense, and coherence remain valid under changing conditions. It highlights the need for a framework that preserves truth, coherence, and orientation under conditions of temporal change.

    Postrelativismus: Wahrheit, Kohärenz und die Temporalität der Adäquanz · 2026 · DOI

  • Future research should continue to explore the concept of personal identity in ontological materialism. Further studies could investigate the implications of the paper's findings for our understanding of personal responsibility and self-care.

    The Limits of the Self in Ontological Materialism: On the Indeterminacy of Exclusive Personal Identity · 2026 · DOI

  • The study highlights the need for further examination of the exclusivity claim.

    The Limits of the Self in Ontological Materialism: On the Indeterminacy of Exclusive Personal Identity · 2026 · DOI

  • The formal ontological analysis employs essential dependence relations (E-RIG and E-GEN) and hyperintensional machinery from Fine, Lowe, and Correia, but does not formally derive or test whether these dependence structures can be computationally or algorithmically instantiated to predict or classify natural kinds based on property clusters without prior ontological commitment.

    Natural kind fundamentalism · 2026 · DOI

  • The article remains entirely on the plane of coordinate geometry and does not rise to the problem of ontological foundation. The article does not contemplate primordial Nothingness, does not discipline infinity, and does not treat transcendence as information-radiation produced in atomic relations.

    THE MODAL DISCIPLINE OF THE INVERSE TRANSFORMATION OF RINDLER SPACETIME: A critical–propositional analysis of Inverse-transformation of 4-dimensional Rindler spacetime, by Sangwha-Yi, in confrontation with the Theory of Objectivity · 2026 · DOI

  • The authors note that efforts to define determinism precisely have exposed deep methodological disagreements.

    Deterministic Theories · 2026 · DOI

  • Inconsistencies in the original publication concerning dimensional notation and units. Notational and dimensional inconsistencies concerning the name of the effective-continuity-factor equation.

    Correction: Kurtz, A.G. The Frame Survival Model of Conscious Continuity: A Theoretical Framework for Subjective Experience in a Branching Universe. Philosophies 2026, 11, 14 · 2026 · DOI

  • Hicks articulates a distinctive and underexplored source of a line of criticism that later became central to attacks on the Given.

    The Mind Does Not Make Jumps · 2026 · DOI

  • Further study of the implications of the theorem for various fields, including mathematics, philosophy, and physics - Further development of the theorem…

    Zhu-Liang Theorem on Truth as Recursive Meta-Nested Function ——Based on Category-Theoretic Construction from Root Consensus of Causality and Self-Consistency (Complete Version) · 2026 · DOI

    Diving for pearls: conceptual abandonment, conceptual engineering, and the limits of thought and language · 2026 · DOI

  • The paper identifies a gap in the explanatory basis of normative neopragmatism. The paper argues that normative neopragmatism leaves its normative basis less satisfactorily explained.

    Naturalism, Normativity, and Neopragmatism · 2026 · DOI
