Abstract

Epistemology has historically developed around human perceptual and cognitive capacities. This is not a problem insofar as epistemology is constructed for humans, nor is it a reason to reject the achievements accumulated within that tradition. However, if Observer Intelligences with perceptual and cognitive structures different from those of humans can exist, there is no need to treat the human observer as the absolute epistemic origin. This paper does not aim to replace existing epistemology with a new epistemology. It positions the minimal relations presented by the Structure–Observer Interpretation Hypothesis (SOIH) [1], the Observer-Relative Knowability Hypothesis (ORKH) [2], and the External Axiomatic Requirement Hypothesis (EARH) [3] as a single epistemic stage. On this stage, humans, AI, and other possible intelligences can all be placed as Observer Intelligence O. It is not necessary to determine in advance whether present-day AI constitutes an Observer Intelligence different from humans. The purpose is to provide common coordinates that remain usable if different Observer Intelligences exist, while preserving the epistemological achievements accumulated with respect to humans.
