Philosophy of the Art of the Path

El sendero del caminante (v5, 2025)

Adrián Martínez Estellés

The most complete book on the Philosophy of the Art of the Path. It explores the two fundamental dualities, the intrinsic core, and the practice of the path toward integral self-knowledge.

  • The two dualities: Ego/Consciousness and, as a structural correspondence, primordial Mass/Space
  • The intrinsic core: Your singular starting configuration
  • The subjective dual metric: How you interpret reality
  • The social layers: How society conditions you

El Arte del Camino

Philosophy and ontology of the tensorial dual unity

Adrián Martínez Estellés

Ontological treatise on the dual structure of reality. It explores how the irreducible tension between two poles (mass/space, ego/consciousness) generates all possible experience.

  • Dual unity: Reality is neither One nor Many
  • Irreducible tension: The poles cannot exist separately
  • Cosmos–mind correspondences: a shared grammar, not the same physics

La arquitectura del caminante

Book Six · v7, 15 September 2026

Adrián Martínez Estellés

The current version of the Philosophy of the Art of the Path. It sets the criterion by which its correspondences with the MCMC are read: a structural analogy between two independent works, never an experimental equivalence.

The current canonical record of the model, refounded on eight ontological axioms, with the errata FE-08-2026, which prevails where it reclassifies a status.

  • The eight axioms and the deductive chain
  • Collapse thresholds and the Law of the Decade
  • Classification of the results and seven open fronts

Adrián Martínez Estellés

Second technical treatise on the MCMC. It includes a review of the potential V(ΦAd;S), the S↔t↔z map, derivation of dark energy from the tensional potential, and a formulation of a CMB fit with CLASS/CAMB. Historical content: the fits that the program has run since then favor ΛCDM (see the comparison).

  • Comprehensive review of the potential V(ΦAd;S)
  • S ↔ t ↔ z map and tensorial chronology
  • Derivation of effective dark energy
  • Boltzmann implementation (CLASS/CAMB)
  • Formulation of a CMB fit (not run in this version)
