Incommensurabilité, Orthodoxie et Physique des Hautes Etrangetés, Proposition d’un modèle à 6 niveaux pour les Phénomènes Paranormaux

This document, the second part of an article published in the July 2007 issue of 'Lumières dans la Nuit' (No. 386), is authored by Jacques Vallée and Eric W. Davis. It explores the application of semiotics—the study of signs and symbols—to the study of Unidentified Aerial Phenomena (UAP) and extraterrestrial intelligence. The authors argue that traditional SETI approaches, which rely on electromagnetic signals, may be insufficient. Instead, they propose a 6-level model to analyze paranormal phenomena, suggesting that the 'absurd' behavior often reported in abduction cases may not be random, but rather a sophisticated defensive or communicative strategy. The text draws heavily on the work of philosophers like Charles Sanders Peirce and linguists like Ferdinand de Saussure to explain how signs are interpreted. The authors suggest that UAP may be using 'icons' or signs that are designed to be interpreted in specific ways by human observers, potentially to manipulate human consciousness or to mask their true nature. The paper also references research by Kuiper, Freitas, and Stride regarding adaptive programs and mimicry. The document concludes by suggesting that modern science needs a multidisciplinary approach to understand these phenomena, moving beyond traditional scientific boundaries to account for the complex, often confusing nature of UAP encounters.
