Synopsis

Plant Cognition is a research domain concerned with experimentally testing plants’ capabilities to perceive, respond to, and learn from interactions and other experiences/stimuli. Some sub-interests include root interactions, plant spatial awareness, plant social systems, plants learning to anticipate through Classical Conditioning, plant decision-making triggered by environmental stresses, and possible similarities between plant structures and animal nervous systems. Associated discourses and constructs include:
  • Extended Cognition in Plants (André Geremia Parise, Monica Gagliano, Gustavo Maia Souza, 2020s) – an adaptation of Extended Cognition to the more-than-human world, concerned with the role of mediation of root systems and Mycorrhizal Networks in enabling cognitive abilities of communities of plants
  • Mycorrhizal Network (Common Mycorrhizal Network) – an underground network of mycorrhizal fungi found among roots of plant communities

Commentary

As might be anticipated, most commentary on and criticism of Plant Cognition have two main foci: (1) entrenched conceptual boundaries between animals and plants, and (2) entrenched brain-based definitions of cognition. Regarding the former, in a tone that is eerily reminiscent of debates on animal cognition a few decades ago and debates on human cognition a century ago, many are uncomfortable with the suggestion that plant activity might be better framed in terms of Darwinian dynamics than Newtonian mechanics. That is, talking about how plants react (i.e., drawing on physics) is fine, but assertions of choice, communication, and decision-making are bridges too far. Regarding the latter, some regard the observation that plants don’t have brains as clear and sufficient evidence that principles of cognition cannot be applied. Subdiscourses include:
  • Brain Chauvinism (Kevin Warwick; 2010s) – the tendency to reject notions of plant intelligence and consciousness on the basis of a conviction that such phenomena rely on a human-like central nervous system
At the other extreme, some regard the emergence of theories of Plant Cognition as overdue and underdeveloped recognitions of ubiquitous cognition:
  • Absolute Idealism (Georg Wilhelm Friedrich Hegel, 1810s) – the perspective that all of reality is a manifestation of an absolute spirit or mind
  • Animism (ancient) – the belief that nonliving aspects of the more-than-human world, such as inanimate objects and natural phenomena, have qualities of living forms, such as emotions and goals
  • Hylozoism (ancient) – the perspective that all physical forms are alive or, on some level, animate
  • Mind Stuff (William Clifford, 1870s) – the suggestion that all matter has consciousness. More descriptively, Mind Stuff is asserted to be the substance that constitutes reality, externally manifested as matter and internally manifestated as mind.
  • Panpsychism (Psychism) (ancient) – the conviction, whether informal belief or formal philosophy, that all of reality is minded – that is either part of or infused with mind-like qualities, which some commentators argue include sentience, subjective experience, intelligence, and/or intention
  • Pancognitivism (David Ray Griffin, 1990s)– the assertion that, at a fundamental level, thought is present everywhere
  • Spirituality – a variously interpreted notion that is most often understood in terms of belief in or attendance to layers or aspects of reality that influence or direct events in the world. Such aspects or forces are deemed either immanent in all material forms or incorporeal. Subdiscourses include:
    • Ecospirituality (Ecological Spirituality) – an umbrella term used to refer to movements that share one key tenet: Humans, who are constitutionally entangled with all living forms, must be mindful of and act with respect toward all aspects of the cosmos
  • Vegetative Soul (Aristotle, 300s BCE) – a soul able to growth and reproduce, but unable to perceive or think (compare: Sensitive Soul, under Animal Cognition; Rational Soul under Primate Cognition)

Authors and/or Prominent Influences

Diffuse

Status as a Theory of Learning

Plant Cognition is a theory of learning – and one that is proving a useful device for compelling commentators to reveal their deep-seated (usually dualism-based) assumptions and beliefs about learning.

Status as a Theory of Teaching

Plant Cognition is not a theory of teaching.

Status as a Scientific Theory

In spite of the reservations of its many detractors, Plant Cognition is a scientific theory – in part because proponents (unlike many detractors) are explicit about assumptions, metaphors, and definitions surrounding learning and cognition. As well, Plant Cognition has a substantial and rapidly growing evidence base.

Subdiscourses:
