Learning Plants: Semiosis Between the Parts and the Whole

In this article, I explore plant semiosis with a focus on plant learning. I distinguish between the scales and levels of learning conceivable in phytosemiosis, and identify organism-scale learning as the distinguishing question for plant semiosis. Since organism-scale learning depends on organism-scale semiosis, I critically review the arguments regarding whole-plant functional cycles. I conclude that they have largely relied on Uexküllian biases that have prevented an adequate interpretation of modern plant neurobiology. Through an examination of trophic growth in plant roots, I expose some conceptual difficulties in attributing functional cycles to whole-plants. I conclude that the mapping of resource areas in the root system is a learning activity requiring higher-scale sign activity than is possible at the cellular scale, strongly suggesting the presence of organism-scale functional cycles. I do, however, question whether all perception-action cycles in organisms are accompanied with organism-scale semiosis.

Biological Pedagogy as Concern for Semiotic Growth

Deweyan pedagogy seeks to promotes growth, characterized as an increased sensitivity, responsiveness, and ability to participate in an environment. Growth, Dewey says, is fostered by the development of habits that enable further habit formation. Unfortunately, humans have their own habitual ways of encountering other species, which often do not support growth. In this article, I briefly review some common conceptions of learning and the process of habit-formation to scope out the landscape of a more responsible and responsive approach to taking growth seriously. What emerges is a reflexive biosemiotics that has humans explicitly concerned with the in situ emergence of new signification in themselves and in other organisms. This requires we take a pedagogical stance in our attitudes and practices towards other species, which we can enrich with insights derived from re-interpreting traditional empirical studies. By freeing the habit-forming process from confining stereotype, a biological pedagogy can enable a more fluid and creative biosphere, unencumbered to explore unfolding possibilities in semiotic space.

The Semiosis of “Side Effects” in Genetic Interventions

Genetic interventions, which include transgenic engineering, gene editing, and other forms of genome modification aimed at altering the information “in” the genetic code, are rapidly increasing in power and scale. Biosemiotics offers unique tools for understanding the nature, risks, scope, and prospects of such technologies, though few in the community have turned their attention specifically in this direction. Bruni (2003, 2008) is an important exception. In this paper, I examine how we frame the concept of “side effects” that result from genetic interventions and how the concept stands up to current perspectives of the role of organism activity in development. I propose that once the role of living systems in constructing and modifying the informational value of their various developmental resources is taken into account, the concept of a “side effect” will need to be significantly revised. Far from merely a disturbance brought about in a senseless albeit complex system, a biosemiotic view would take “side effects” as at least sometimes the organism’s active re-organization in order to accommodate or make use of novelty. This insight is nascent in the work of developmental plasticity and niche construction theory (West-Eberhard 2003; Odling-Smee et al. 2003), but it is brought into sharper focus by the explicitly interpretive perspective offered by biosemiotics. Understanding the “side effects” of genetic interventions depends in part on being able to articulate when and where unexpected consequences are a result of semiotic activity at various levels within the system. While a semiotic interpretation of “side effects” puts into question the naive attitude that would see all unintended side effects as indications of disturbance in system functionality, it certainly does not imply that such side effects are of no concern for the viability of the organisms in the system. As we shall see, the fact that such interventions do not respect the translation of information that occurs in multi-level biological systems ensures that disruption is still likely. But it does unprivilege the human agent as the sole generator of meaning and information in the products of biotechnology, with important consequences on how we understand our relationship with other species.

Deweyan Education and Democratic Ecologies

From a Deweyan perspective, the capacity to learn is enabled or restricted by the clutch of ones habits, which are established and maintained by the mutual eliciting of action and reaction between an organism and its environment. Relationships that constrict the capacity for organisms to interact and learn from each other are undemocratic so far as they curb the direction and suppleness by which mutual growth can occur. Dewey saw that education and democracy were therefore inseparable pursuits. However, he developed a conceptual orientation that prevented entry for other species. This article seeks to open a Deweyan approach to considering ecological communities politically and pedagogically. Ecosystems, like human societies, form and develop through complex learning interactions. This has been recognized for centuries by local and indigenous groups, and more recently by modern science in differently operating biological processes, from the Baldwin effect, to niche constructionism, and epigenetic inheritance. As Dewey continuously noted, the immediate encounter is a necessary but not a sufficient condition to ensure growthful, democratic environments, because patterns of behavior, thinking, and affect are channeled by the structural contexts within which encounters occur. It is therefore necessary that educators focus on the experimental reconstruction of infrastructure, buildings, institutions, technologies, and other material structures that habituate us to normalize miseducative and undemocratic relationships with our own and with other species.

Deweyan Psychology in Plant Intelligence Research: Transforming Stimulus and Response

This chapter argues that plant intelligence needs to be considered as a teleological activity, whereby the plant organizes and coordinates itself and its environment in a goal-based way. If plant biologists follow behaviourist (and cognitivist) psychology in reducing intelligence to mechanisms of the mind, they risk repeating the dementalization of the organism that was inherent in behaviouristic animal theory. I employ Deweyan transactionalism to explore why a new empirical approach to plant intelligence is necessary and what such an approach might look like.

Facing loss: pedagogy of death

Abstract Loss, impermanence, and death are facts of life difficult to face squarely. Our own mortality and that of loved ones feels painful and threatening, the mortality of the biosphere unthinkable. Consequently, we do our best to dodge these thoughts, and the current globalizing culture supports and colludes in our evasiveness. Even environmental educators tend to foreground ‘sustainability’ whilst sidelining the reality of decline, decay, and loss. And yet, human life and ecological health require experiencing ‘unsustainability’ too, and a pedagogy for life requires a pedagogy of death. In this paper we explore experiences of loss and dying in both human relationships and the natural world through four different types of death affording situations, the cemetery, caring-unto-death, sudden death, and personal mortality. We trace the confluence of death in nature and human life, and consider some pedagogical affordance within and between these experiences as an invitation to foster an honest relationship with the mortality of self, others, and nature. We end by suggesting art as an ally in this reconnaissance, which can scaffold teaching and learning and support us to courageously accept both the beauty and the ugliness that death delivers to life.

Genetic Engineering and Human Mental Ecology: Interlocking Effects and Educational Considerations

This paper describes some likely semiotic consequences of genetic engineering on what Gregory Bateson has called “the mental ecology” (1979) of future humans, consequences that are less often raised in discussions surrounding the safety of GMOs (genetically modified organisms). The effects are as follows: an increased 1) habituation to the presence of GMOs in the environment, 2) normalization of empirically false assumptions grounding genetic reductionism, 3) acceptance that humans are capable and entitled to decide what constitutes an evolutionary improvement for a species, 4) perception that the main source of creativity and problem solving in the biosphere is anthropogenic. Though there are some tensions between them, these effects tend to produce self-validating webs of ideas, actions, and environments, which may reinforce destructive habits of thought. Humans are unlikely to safely develop genetic technologies without confronting these escalating processes directly. Intervening in this mental ecology presents distinct challenges for educators, as will be discussed.

The interspecies educator's cybernetic world

– The purpose of this paper is to interconnect pedagogy and biology via second-order cybernetics. , – The approach taken is that of a synthesis. , – Biology can better deal with intersubjectivity within and between species by incorporating approaches and theory from education inquiry. Conversely, educators can de-anthropocentrize their discipline by entering into learning relationships with other species. By rallying around the concept of “eduction”, second-order cybernetics plays a role in both syntheses. , – De-anthropocentrizing education could have practical value in creating ecologically relevant education for children and in developing more integrated environmental impact assessments. , – Finding convergence between the study of life and forms of practitioner inquiry in education research, and connecting these to the environmental movement.
