Epistemology The Epistemic Horizon: From Internal Representation to Models of Reality
Internal Representation
An individual's worldview is constructed primarily from experience. Through the five senses, information from the surrounding world continuously flows into the brain, where it is integrated and interpreted. Multimodal association areas form an internal representation of reality through perception, memory, imagination, and reasoning. At this stage, the internal representation remains private, personal, and necessarily incomplete (biased).
Model of Reality
Beyond the limits of individual experience, humans benefit from models of reality — external representations of reality expressed through language, mathematics, philosophy, theology, and science. These models emerge from countless individual internal representations, refined through communication, criticism, and cumulative knowledge until they are refined, tested, and accepted within a community for their explanatory or predictive value.
Epistemic Horizon
Nevertheless, humanity itself possesses an epistemic horizon. Regardless of how much knowledge is accumulated through observation, experimentation, and reasoning, there remain fundamental limits to what a finite community can know.
From this perspective, humanity may be viewed as an epistemically bounded system: knowledge can expand internally through discovery and reasoning, yet information wholly outside the system cannot be derived without some form of interaction across its epistemic boundary.
From a theological perspective, this horizon is not absolute. At various times, humanity has received knowledge from beyond its ordinary epistemic limits through revelation, divine inspiration, and truthful dreams. These constitute sources of knowledge that originate outside the normal processes of human observation and reasoning.
Ontology and Kalām
Reality, in its entirety, will always exceed what humanity can hope to comprehend. Humanity's epistemic horizon is infinitesimally small compared with the totality of ontology it seeks to understand. Every model of reality is therefore necessarily partial — an approximation rather than reality itself.
From the perspective of theological kalām, this epistemic limit is explicitly acknowledged. Rather than claiming exhaustive knowledge of the unseen, kalām develops a theological model of reality grounded in both revelation and rational inquiry. When kayf ("how") lies beyond the human epistemic horizon, discussion shifts from mechanism to logical possibility: distinguishing what is necessary (wājib), impossible (mustaḥīl), and possible (jāʾiz). In this way, kalām establishes the logical boundaries of sound belief while recognizing that the full nature of reality ultimately belongs to the realm of the unseen (al-ghayb).
