Frequently Asked Questions¶

Short answers to common questions about the Creative Determinant (CD) framework.

Is this supposed to be a full theory of mind?¶

No. CD is a framework for certain aspects of coherence, viability, and meaning-making in cognitive and computational systems. It has stated limitations (Section 6 of the paper, Open Problems) and is not a complete theory of consciousness, phenomenology or intelligence.

Does the PDE "explain" semiotics or enactivism?¶

Not directly. The PDE is a mathematically tractable proxy motivated by semiotic and enactivist ideas (care, coherence, contradiction, autopoiesis). The relationship between the PDE model (weak coherence) and the pointwise CD constraint (strong coherence) is an open problem. See Open Problems #1.

Can I use this framework without accepting the philosophical interpretation?¶

Yes. The PDE structure, existence/nontriviality theorems, and spectral results stand on their own as nonlinear analysis. You can treat the interpretive layer (Section 4) as motivation only and work purely within the mathematical framework.

Is the CD condition testable on real systems?¶

Yes, in principle. Definition 5.1 specifies measurable quantities: a coherence observable and Jacobian determinants. The challenge is operationalizing these on high-dimensional systems (e.g., neural networks). See the Research Roadmap for proposed tests.

What is the "semiotic manifold" M in a real neural network?¶

Open question. \(M\) is an abstract space of meanings or interpretations. Extracting it from a trained network requires manifold learning, dimensionality reduction, or other techniques. See Open Problems #7 and Research Roadmap #1.

How do I extract the fields κ, γ, μ from data?¶

No general method yet. The canonical closure \(b = \kappa\gamma - \lambda\mu\) provides a structure, but inferring \(\kappa\) (care), \(\gamma\) (coherence), and \(\mu\) (contradiction) from observables is system-dependent and currently requires hand-crafted proxies. Principled extraction is open (Open Problems #7).

Is there existing code I can run?¶

Yes. The Jupyter notebook cd_pde_demo.ipynb covers eigenvalue checks, residual-validated nonlinear solves in 1D and 2D, threshold crossings, canonical closure sweeps, the verified finite-graph example and a 3D eigenvalue illustration. The Quickstart shows how to run it.

Can I propose changes to the core framework?¶

Yes. Open an issue tagged proposal or critical describing your proposed change or challenge. Constructive critiques and falsification attempts are first-class contributions. See Contributing.

What license is this under?¶

Apache 2.0. See LICENSE for full terms.

All contributions are licensed under the same terms. If you contribute substantial original work, you may also publish it separately under your own name without asking permission.

Who is this for?¶

CD is intended for: - Researchers in PDE theory, dynamical systems, AI interpretability, cognitive science, or philosophy of mind looking for cross-disciplinary synthesis. - Practitioners wanting to operationalize "coherence" or "viability" in computational systems. - Students seeking a worked example that connects mathematics and conceptual interpretation.
