- Michael Levinauthored
- Nicolas RouleauauthoredCo-author; neuroscientist studying embodied and bioengineered tissues to model neural diseases and minimal cognitive systems.
Concepts (16)
concept
- ConsciousnesscitesCore concept: capacity to experience as a subject; argued to be substrate-independent and achievable across diverse biological systems.
- TeleonomycitesGoal-directed behavior framework; referenced in plant cognition context.
- Idea that functions can be achieved without contingency of particular material or physical medium; used to argue sentience need not require neural tissue.
- Philosophical framework asserting same function can be implemented by very different systems; key to arguing sentience is substrate-independent.
- Plant SentiencecitesPossibility that plants experience subjective felt states; main topic of the commentary.
- Concept that structurally dissimilar brain regions achieve same functional outcomes; supports claim that different substrates can realize same cognition.
- Theory Of MindcitesCognitive capacity attributed to humans and animals; referenced as basis for mentalism intuitions.
- CognitioncitesMental actions including sentience; can be achieved by different biological and non-biological substrates.
- BlindsightcitesExample of biological degeneracy: visual responses mediated by subcortical and brainstem nuclei independent of cortex; supports multiple realizability of cognitive functions.
- Learning mechanism observed in plants; cited as evidence of cognitive function.
- embodied behaviourscitesObservable actions used to infer cognition, including verbal self-report.
- Load-bearing summary statement suggesting vastness of potential consciousness forms beyond current conception.
- Evaluation criteria for sentience based solely on observable response patterns, independent of substrate.
- Double StandardcitesThe inconsistent willingness to infer sentience in animals vs. plants based on similar behavioral evidence.
- Risk AssessmentcitesCognitive behavior of evaluating risk, exhibited by plants according to S&C.
- Action PotentialscitesElectrical signals that plants display, propagating along vascular networks, analogous to animal neural signals.
Claims (7)
claim
- Stronger version: all cognition attributions rely on observable behavior.
- Central multiple-realizability claim of the paper, from abstract and §2.
- Reinforcement of substrate independence: Earth-like neural circuits are unlikely to be the sole substrate.
- Prescriptive claim that ignoring substrate will unify diverse fields.
- Conditional claim urging consideration of non-neural tissues for cognition.
- Call to extend the inference of sentience to non-biological systems as well.
- First sentence of the paper, establishing the inferential nature of all sentience attributions.
Frameworks (2)
framework
- A conceptual framework for understanding cognition and intelligence across diverse substrates—including evolved biological systems, artificial systems, and bioengineered systems—using empirically-grounded, gradualist approaches. TTAME enables comparative analysis of mind-like phenomena regardless of the physical or biological substrate in which it emerges, facilitating cross-disciplinary study of unconventional intelligences.
- Variational EcologycitesFramework for physics of sentient systems; cited for understanding consciousness across substrates.
