The Brain’s Reflection of the External World

This article explores the intriguing concept that the brain may reflect the causal relationships of the external world through consciousness. The authors propose a formal model of these causal relationships as probabilistic maximally specific rules, addressing the problem of statistical ambiguity. By making all possible inferences from these causal relationships, the brain forms a consistent and unambiguous model of the perceived world.

Formal Model and Unambiguous Inference

The suggested formal model presented in this paper provides a key feature of unambiguous inference. This means that given consistent premises, we can infer a consistent conclusion. This not only ensures logical consistency but also enables the formation of a comprehensive model of the perceived world based on all possible inferences.

Natural Classification and Causal Models

The authors delve into the concept of a “natural” classification proposed by John Stuart Mill, which describes how objects’ attributes can form fixed points. These fixed points represent cyclical inter-predictable properties and lay the foundation for a classification system of the external world.

In addition, the article references the notions of “natural” categories and causal models put forth by Eleanor Rosch and Bob Rehder. The fixed points of causal relationships between objects’ attributes, which we perceive, are shown to formalize these notions. This suggests that the brain organizes and categorizes information based on the causal relationships it detects in the external world.

The Role of Integrated Information

Integrated information theory, introduced by G. Tononi, is discussed as a framework for understanding how the brain processes information to form “natural” concepts that align with the “natural” classification of objects in the external world. The theory suggests that integrated information plays a crucial role in accurate object identification by the brain.

Coding Digits Experiment

To illustrate the formation of fixed points, the article presents a computer-based experiment using coded digits. This experiment highlights how fixed points can emerge when objects possess distinct attributes that can be correlated and categorized.

Overall, this insightful article presents a compelling argument for how the brain reflects and models the external world through causal relationships. The formal model, unambiguous inference, natural classification, and the role of integrated information provide a comprehensive framework for understanding the brain’s perceptual processes. Future research could explore the application of these concepts to other domains and expand our understanding of how consciousness emerges from the brain’s processing of causal relationships.
