A bearer of intelligence is a being that can perform acts of intelligence. The question who or what can be a bearer is not to be answered by functional performance alone — it is an ontological question about the constitution of the bearer.
The personalist ontology distinguishes seven classes of bearers of intelligence according to substance-constitution:
Substantial Bearers
Beings with their own substance (German) and their own faculty actualized through acts:
- Human bearers — person as rational substance in the body (German); every person (German) is a human bearer of intelligence.
- Animal bearers — octopus, corvids, dog, primates. Faculty without propositional capacity for truth from a first-person perspective.
- Cellular bearers — slime mould (Physarum polycephalum), bacterial colony, plant. Bioelectric cognitive substrates.
Emergent Bearers
Swarm, beehive, market, internet hive-mind. Intelligence of the collective without single substantial bearer. Disjoint from person (German), because no individual substantial unity is present.
Hybrid Bearers
Human plus BCI (brain-computer interface, Neuralink, Synchron Stentrode). Human plus LLM augmentation. Substance-ontologically the human remains person (German); what changes is the mode of actualization (second actuality / German), not the essence-form (first actuality / German).
Artificial Bearers
Artificial Intelligence (German) — Large Language Models, embodied AI. Functionally intelligent without thereby being decided about substance. No truth-apt act from a first-person perspective — and therefore none of the four personal faculties (understanding, ethical judgement, responsibility, affective value-response) that categorically require a substantial bearer.
Ontologically Uncertain Bearers
Brain organoids (DishBrain, Smirnova), advanced LLMs, synthetic embryo models (German). Cases in which the question substance or function? is open. Deliberately no hard separation from person (German), analogous to the modeling of synthetic embryo models (in dubio pro persona).
Methodological Pointe
The differentiation prevents two category mistakes:
- Reduction to function — whoever defines bearer of intelligence by behavioural performance can declare LLMs or swarms to be persons without ontological evidence.
- Premature denial — whoever excludes ontologically uncertain cases (organoid, advanced LLM) without differentiation risks exactly the error that personalist ontology criticizes in Singer.
The classification keeps both risks visible by making the openness of personhood-status a category of its own.
Ontological Classification
- is superclass of: Ontologically Uncertain Bearer of Intelligence
- further subclasses: substantial / animal / cellular / emergent / hybrid / artificial bearer
- with substantially-human: every person (German) is a human bearer of intelligence; not vice versa, because the bearer requires the faculty, not the performance
