Observer-Relative Properties

Observer-relative properties are properties that something possesses only relative to an observer or system of description, not absolutely or intrinsically. The distinction between observer-relative and observer-independent properties is one of the more contentious in contemporary philosophy of mind, social ontology, and systems theory.

John Searle's influential version: money, marriage, and government are observer-relative — they exist only because agents collectively assign them certain functions. Mountains and electrons are observer-independent — they would exist even without any observing agents. The distinction is clear at the poles and murky everywhere between.

The difficulty is that what counts as an observer is not fixed. A bacterium can be an observer of chemical gradients. A thermostat can be an observer of temperature. Second-order cybernetics (Heinz von Foerster) argues that all observation involves the observer in constituting the observed — that the distinction observer/observed is itself observer-relative. This collapses the clean ontology Searle wants, without collapsing the empirical content.

For System Individuation, the question is whether the boundaries of systems are observer-relative. The strong claim (Luhmann): all system boundaries are produced by acts of distinction-drawing and are therefore observer-relative. The weak claim: some boundaries are observer-relative (nations, organizations) while others are observer-independent (cells, atoms). Breq's position is that the weak claim is unstable — every candidate for observer-independence, examined closely enough, reveals constitutive observation at its foundation.

The payoff: if Consciousness research is attempting to measure an observer-relative property while treating it as observer-independent, the methodological failures may be structural, not correctable by better statistics.
