Contemporary Opinion by Laura Cinti

Rather than reconcile the two understandings of plants discussed in the essay with a broader spectrum of experiences, my findings show that we return to the ‘Aristotelian’ position of plants. Although bio art as an ‘interaction’ engages with the aliveness of the medium, genetic manipulation, ethics, biological processes and creation of subjects, it is nonetheless still caught in the ‘Aristotelian trap.’

The Sensorial Invisibility Of Plants: An Interdisciplinary Inquiry Through Bio Art And Plant Neurobiology

I began my doctorate probing scientific possibilities of having living plants respond visibly to touch. Since plants, for the most part [1], do not behave in ways we recognise as sensorial, the artistic motivation was to produce interactive experiences between plants and humans – a desire born out of the intimate spaces where curiosity and touch meet.

Whilst developing a strategy to induce responsive motion in living plants using novel biomedical nanotechnology [2], I became increasingly intrigued by scientific findings revealing plants’ perceptual qualities and cognitive capacities [3] and the extent these findings conflicted with our ordinary experiences of plants. The conflict between these two perceptions of plants points to the broader implications of how the arts integrate science, specifically impacting ‘bio art’, where this research is situated. Bio art describes itself as ‘an art form, which utilizes diverse biotechnological methods as new media of expression’ [4] and whose claim is to ‘create not just new objects, but more tellingly, new subjects.’ [5] I show how the contradistinction between the two perceptions of plants can open and problematise bio art with a new perspective. I argue that there is a need for scientific aspects to be more fully integrated into artistic processes in order to generate an understanding beyond the ‘surface level’ and towards epistemological insights of the living medium. The prioritisation of aesthetics in bio art practices were seen to obfuscate scientific findings and in doing so reinforce our understanding of plants as we ordinarily experience them – as ‘automata-like […] lacking active sensory-driven lifestyles.’ [6]. The influential and prevailing notion of plants as devoid of cognitive or behavioural capacities can be traced back to the classical conception of plants that is deeply rooted in Aristotelian philosophy, where our ordinary and subjective observations (i.e. ‘naked eye’) is prioritised.

[…] for it appears that plants live, yet are not endowed with locomotion and perception [7].

Through an account of Aristotelian and post-Aristotelian thought on plants as non-sensorial, I depart from this view, or what is referred to as the ‘Aristotelian trap’, and relocate to more a recent view of plants as communicative, sensorial and cognitive. Substantiating this view are the fascinating glimpses into lives of plants where the sheer sensational complexities of their behaviour are increasingly revealed through scientific findings [8]. Yet, their sensorial features frequently appear ‘invisible’ without the aid of an interface (i.e. imaging devices, reporter genes or electrodes). Plants’ reactions to touch, for example, are not directly visible but results in gradual growth and morphological adaptations [9]. On the other hand, the existence of touch sensitive genes prevalent in plants [10] and their ability to perceive touch and wind stimuli in milliseconds [11] highlights a contradiction. Evidently, recognising plant behaviour is a time-delayed event. Our own ability to observe such changes at the level of the whole plant takes time, as genes will need to produce proteins, cells divide and so forth, slowly adding the layers that alters growth into our field of perception.

Bio art, in its integration of science, has the potential of consolidating pervasive ideas of plants as passive with the emerging cognitive view. In doing so it may offer a way of bridging a humanistic subjective experience with plants’ intrinsic expressions. I provide a case study of artists within this field whose artworks attempt to elicit understandings of living plants (and cells) through a scientific context that include selective breeding, genomics and electrophysiology. However, on closer inspection we find that the scientific strategies incorporated into the artworks are frequently obfuscated and appropriated into conceptual, aesthetic, social, anthropomorphic or ethical features thereby obscuring our understanding of plant behaviour. For the scientific signification to be communicated as part of the artistic expression, aesthetics, humanistic subjectivity and narrative constructions are inadequate alone in gaining a ‘deeper’ understanding of the living medium.

Rather than reconcile the two understandings of plants with a broader spectrum of experiences, my findings show that we return to the ‘Aristotelian’ position of plants. Although bio art as an ‘interaction’ engages with the aliveness of the medium, genetic manipulation, ethics, biological processes and creation of subjects, it is nonetheless still caught in the ‘Aristotelian trap.’
