Observer, Energy & Information
Cognition, attention, and the metabolic cost of knowing
Overview
The observer processes information using energy: every thought, every perception, every act of attention has a metabolic cost measurable in calories and ATP. The brain, which constitutes roughly two percent of body mass, consumes twenty percent of metabolic energy precisely because it is an information-processing organ. In quantum mechanics, the act of observation — extracting information from a system — is an irreversible energetic event. This triad captures the biophysics of cognition and the thermodynamics of knowing.
Central Tension
The tension is between the observer's informational ambitions and their energetic constraints. Acquiring, processing, and storing information all cost energy, and the observer's energy budget is finite. Attention is selective because the brain cannot afford to process all available information simultaneously. Sleep is necessary because neural information processing generates metabolic waste that must be cleared. The observer is an energy-limited information processor, and the limits of energy shape the limits of knowledge.
Key Philosophical Questions
- Is consciousness an energy-efficient way of processing information, or is it energetically wasteful compared to unconscious processing?
- Does the observer's finite energy budget fundamentally limit the amount of information they can know?
- Is attention the observer's mechanism for allocating scarce energy to the most important information?
- Could an observer with unlimited energy process unlimited information — or are there informational limits independent of energy?
Schools of Thought
The observer is a thermodynamic system that processes information within energetic constraints; consciousness is the subjective aspect of energy-intensive neural computation.
Observation is an energetic extraction of information from a quantum system; the observer's role is constitutive, and the energy cost of measurement is fundamental, not incidental.
Every energetic-informational process has an experiential aspect; the observer is simply a highly integrated instance of the universal energy-information-experience triad.
The observer is an energy-consuming node in a universal information network; consciousness is what locally complex information processing feels like when fueled by sufficient energy.
Human observers are finite energy-information processors sustained by God's providence. God's own knowing requires no energy expenditure — divine omniscience is not constrained by thermodynamics.
Synthesis
Observer, energy, and information describe the biophysics of mind: a knowing subject fueled by energy, processing information within thermodynamic constraints. Every thought has a caloric cost, every measurement an energetic price, and every act of attention a metabolic budget. The observer is not a disembodied intellect but an energetically sustained information processor — and the limits of energy are the limits of knowledge.
