Consciousness in experimental subjects is typically inferred from reports and other forms of voluntary behaviour. A wealth of everyday experience confirms that healthy subjects do not ordinarily behave in these ways unless they are conscious. Investigation of consciousness in vegetative state patients has been based on the search for neural evidence that such broad functional capacities are preserved in some vegetative state patients. We call this the standard approach. To date, the results of the standard approach have suggested (...) that some vegetative state patients might indeed be conscious, although they fall short of being demonstrative. The fact that some vegetative state patients show evidence of consciousness according to the standard approach is remarkable, for the standard approach to consciousness is rather conservative, and leaves open the pressing question of how to ascertain whether patients who fail such tests are conscious or not. We argue for a cluster-based ‘natural kind’ methodology that is adequate to that task, both as a replacement for the approach that currently informs research into the presence or absence of consciousness in vegetative state patients and as a methodology for the science of consciousness more generally. 1.

In “An introduction to phytosemiotics”, a masterwork of integration, Kalevi Kull defended Martin Krampen’s notion of phytosemiotics. In doing so, he developed the notion of vegetative semiosis. In a later work, he argued that vegetative semiosis is not a branch of semiotics, and so should not be identified with phytosemiotics. Rather, vegetative semiosis is a basic form of semiosis and the condition for animal semiosis, which in turn is the condition for cultural semiosis. All multi-celled organisms, including (...) plants, animals and humans, are characterized by vegetative semiosis. While clearly influenced by Aristotle (and Thomas Aquinas), this characterization of vegetative semiosis makes it easier to relate biosemiotics to current science, to integrate current science into biosemiotics, and thereby to greatly expand the research potential of biosemiotics.

The volume analyzes the natural philosophical accounts and debates concerning the vegetative powers, namely nutrition, growth, and reproduction. While principally focusing on the early modern approaches to the lower functions of the soul, readers will discover the roots of these approaches back to the Ancient times, as the volume highlights the role of three strands that help shape the study of life in the Medieval and early modern natural philosophies. From late antiquity to the early modern period, the (...) class='Hi'>vegetative soul and its cognate concepts have played a substantial role in specifying life, living functions, and living bodies, sometimes blurring the line between living and non-living nature, and, at other moments, resulting in a strong restriction of life to a mechanical system of operations and powers. Unearthing the history of the vegetative soul as a shrub of interconnected concepts, the 24 contributions of the volume fill a crucial gap in scholarship, ultimately outlining the importance of vegetal processes of incessant proliferation, generation, and organic growth as the roots of life in natural philosophical interpretations.

Coma, vegetative state, lock-in syndrome and akinetic mutism are defined. Vegetative state is a state with no evidence of awareness of self or environment and showing cycles of sleep and wakefulness. PVS is an operational definition including time as a variable. PVS is a vegetative state that has endured or continued for at least one month. PVS can be diagnosed with a reasonable amount of medical certainty; however, the diagnosis of PVS must be kept separate from the (...) outcome. The patient outcome can be predicted based on etiology and age. Using outcome probabilities and etiology as criteria, patients can be subdivided in 5 groups and reasonable management guidelines can be suggested. Three levels of care can be provided to PVS patients: high technology, supportive and compassionate care. Pragmatic options for the various subgroups of patients are suggested. Management decisions will remain difficult for both the family and the health-care team. The role of the physician in these difficult cases is to share the decision-making with the family. (shrink)

: This article begins with a discussion of persistent vegetative state (PVS), focusing on concerns related to both diagnosis and prognosis and paying special attention to the 1994 Multi-Society Task Force report on the medical aspects of PVS. The article explores the impact of diagnostic and prognostic uncertainties on prospective thinking regarding the possibility of PVS and considers the closely related question of how prospective thinkers might craft advance directives in order to deal most effectively with this possibility.

Challenges current claims that humans ought to be vegetarians because animals have moral standing.

By denying to vegetal life the core values of autonomy, individualization, self-identity, originality, and essentiality, traditional philosophy not only marginalizes plants but, inadvertently, confers on them a crucial role in the current transvaluation of metaphysical value systems. From the position of absolute exteriority and heteronomy, vegetation accomplishes a living reversal of metaphysical values and points toward the collapse of hierarchical dualisms.

Blossoming from a correspondence between Luce Irigaray and Michael Marder, Through Vegetal Being is an intense personal, philosophical, and political meditation on the significance of the vegetal for our lives, our ways of thinking, and our relations with human and nonhuman beings. Irigaray and Marder consider how the vegetal world contributes to human development by sustaining our breathing, nourishing our senses, and keeping our bodies alive. This generative discussion points toward a more universal way of becoming human that is embedded (...) in the vegetal world. (shrink)

A survey of the medical, ethical and legal issues that surround this controversial topic.

Airedale NHS Trust v Bland establishes three principles among which is the controversial idea that people in a PVS, though not dying, have no best interests and no meaningful life. Accordingly, it is argued, they may have their food and fluids, whether delivered by tube or manually, removed, with the result that they die. Laing challenges this view arguing that not only is this bad medical science, it is unjustly discriminatory and at odds with our duties to the severely disabled. (...) Laing highlights research by Keith Andrews et al and points out that Andrew Devine, in the same Hillsborough disaster, woke up some years after Tony Bland was decided.(Post script) Laing argues elsewhere that after the Mental Capacity Act 2005 the case has become a dangerous springboard for new third parties' to require the removal of food and fluids from the vulnerable incapacitated.

How should we treat patients diagnosed as being in a persistent vegetative state (PVS) or minimally conscious state (MCS)? More specifically, should we treat them as having the full moral status of persons? Yes, or so we argue. First, we introduce the medical conditions of PVS, MCS, and the related conditions of Locked-in Syndrome and covert awareness. Second, we characterize the main argument for thinking diagnosed PVS patients are not persons. Third, we contend that this argument is defeated by (...) mounting empirical evidence for the considerable uncertainty of PVS diagnoses. Fourth, we characterize a new argument for PVS non-personhood suggested by Neil Levy and Julian Savulescu, one intended to accommodate the diagnostic uncertainty. According to this argument, even if diagnosed PVS patients are in fact MCS, it makes no difference because MCS patients are probably not persons either. Fifth, we challenge the new argument by assembling reasons for doubting the claim that MCS patients are not persons. The outcome is that it is fairly uncertain whether diagnosed PVS and MCS patients are persons or not. What should we do in light of this uncertainty? Sixth, we develop and support a guiding precautionary principle, which we call Precautionary Personhood. Finally, we apply the principle to the case of diagnosed PVS and MCS patients: we argue that given substantial uncertainty about their personhood we should go ahead and treat these patients as if they are persons.

The aim of this paper is to examine Francis Glisson’s theory of perception insofar as it concerns the lowest class of living beings: plants. Plants have a special status, they are located between inanimate objects and animals in the hierarchy of being. Unlike the former, they are organic, but unlike the latter they are unconscious. Peculiar to Glisson is the claim that vegetative organization requires self-referential perception. In light of traditional epistemology, this claim may sound puzzling, because we tend (...) to associate self-representation with conscious thought. In order to make sense of Glisson’s self-referential, but unconscious perceptions, the first part of the paper investigates the role of perception in the vegetative process of organization. The second part is a comparative study on two ways of drawing the distinction between unconscious perceptions and conscious sensations. The first one is the Cartesian approach as outlined by Antoine Arnauld in the early 1680s, the second one is Glisson’s theory. In light of the comparison it is argued that Glisson’s is a higher order theory of sensation in which the phenomenon of consciousness requires the delimitation of the all-inclusive, self-referential nature of perception.

The historical development of a field of human knowledge progresses like the solution of a jig-saw puzzle, the full extent of which is completely unknown. What begins as an ocean may become only a lake; what starts as a grove of trees may develop into a forest. As study advances through the decades, the situation is repeatedly surveyed and the interpretation of the whole is modified to accord with the added information. For these reasons, conceptions and generalizations periodically undergo alteration, (...) as effectively stated and discussed by Cooper. Universal conformity in such conceptions is of course hardly to be expected in matters that deal largely with speculation rather than with simple experimental data. (shrink)

According to Descartes, vegetative and sensitive activities, which in the Aristotelian tradition were considered dependent on the soul, are pure effects of corporeal dispositions. What is, however, the relationship between this doctrine and Descartes’s metaphysical claim in the Meditations, namely, that the mind is the only cause of thought? In the Meditations, Descartes does not provide a doctrine of vegetative and sensitive functions, and he does not even establish the canonic Cartesian thesis that they are not dependent on (...) the soul. In claiming that the lowest functions cannot be attributed to the soul, the Second Meditation is not making an ontological point. Nevertheless, in spite of this, the Meditations teach us something very important about the lowest functions: that both vegetative and sensitive functions depend on the soul is not, and never will be, a necessarily true proposition.

Bible myths, fairy tales, and science fictions all offer narratives that imply and sometimes question boundaries for human behavior. By subscription to certain narratives, individuals can enter and leave social groups; by evolving narratives, groups can adjust the realm of the allowable and the realm of the forbidden; and by selective transgression, individuals can gain power beyond that initially granted by the group. All these functions of narrative contribute to the sociobiological vigor of the individuals and groups that subscribe to (...) them, suggesting that the creation and use of narratives has proadaptive functions.

The article briefly analyzes the concept of a person, arguing that personhood does not coincide with the actual enjoyment of certain intellectual capacities, but is coextensive with the embodiment of a human individual. Since in PVS patients we can observe a human individual functioning as a whole, we must conclude that these patients are still human persons, even if in a condition of extreme impairment. It is then argued that some forms of minimal treatment may not be futile for these (...) patients; they may constitute a form of respect for their human dignity and benefit these patients, even if they are not aware of that. Moreover, it is important to consider the symbolic significance of care: while many believe that PVS is a kind of imprisonment, for others providing food and fluids is the only way to testify our proximity to these persons. The best policy would be to provide, as a general rule, artificial nutrition and hydration to PVS patients: this treatment could be withdrawn, after a period of observation and reflection by the family and proxies, on the basis of the proxies' objection to the continuation or of the patient's advance directives specifically referring to this situation.

In ancient Greek ecological thought, vegetality is the most basic ground of life. It is followed by animality and rationality as increasingly active, self-aware forms of life. An ontology of forms of life need not justify a hierarchy among actual living beings, but in practice it often does. This paper shows how the poetic representation of plants resists this slippage. Poetry offers human beings an ecstasis from their own animality so that they can apprehend their participation in the vegetality of (...) living beings as a whole. (shrink)

Assess to quality diets is a basic human right. Geographical challenges and cultural traditions have contributed to the widespread malnutrition present among ethnic minorities of mountainous areas in Northwest Vietnam. Home gardens can play a role in increased diet diversity and micronutrient intakes. However, low production yields and plant diversity in ethnic home gardens have limited their contributions to household food security and nutrition. The pilot study tested a home garden intervention in weekly vegetable harvests and increasing household production and (...) consumption of diverse vegetables year-round. Food ethics issues encountered included limited access to quality food by resource-poor groups, conflicts arising from low preference and value given to some nutritious foods, limited access to information and technology for food production and consumption, each of which were addressed in the study design. The intervention includes: (1) nutrition-focused home garden training and (2) locally-adapted home garden packages consisting of garden planning, technical assistance, and high-yielding seed varieties. Twenty households from two ethnic villages in Son La province participated in the study and were randomly assigned into two groups (intervention and non-intervention). The total vegetable supply from weekly harvests of home garden produce was significantly higher in the intervention households (226 kg) compared to the non-intervention households (39 kg). The intervention group yielded 5.8 and 1.7 times more vegetables by weight and weight per area than those without the intervention. The vegetables were mainly consumed at home for both groups, but the intervention households gave more vegetables as gifts to neighbors. The intervention group cultivated a higher diversity of vegetables with a total of 42 different vegetables compared to 24 in the non-intervention group, which is reflected in an overall higher nutritional yield of vitamin A, iron, other micronutrients and phytochemicals. The home garden training significantly improved the amount, diversity and continuity of household food and nutrient supply. The home garden model is effective and could be scaled up to improve household vegetable supply and consumption, particularly in Northwest Vietnam. (shrink)

Rethinks the soul in plant-like terms rather than animal, drawing from nineteenth-century philosophy of nature.

In this chapter, I investigate the metaphysical assumptions that medieval thinkers considered necessary in order to integrate the vegetative powers and processes into their conception of human beings as composed of a material body and an immaterial soul. My aim is to show that vegetative powers and processes are central to the late medieval debate on faculty psychology and on the unity or plurality of substantial forms. The chapter has two parts. First, I present three different accounts of (...) the ontological status of the vegetative powers in relation to the body and the soul, as found in Thomas Aquinas, William of Ockham, and John Buridan. All three maintain that the vegetative powers belong to the soul but disagree as to whether they are identical with it or somehow distinct from it, especially when the soul in question is immaterial. Second, I investigate how medieval thinkers accounted for the metaphysics behind the operations of the vegetative powers in human beings, who are endowed with immaterial souls, in particular when it comes to procreation and digestion. A pressing problem for the vegetative powers of human beings is how they can produce a new substance when this composite is supposed to include an immaterial soul which is not naturally generated. Regarding procreation, one can distinguish two different approaches: dispositional generation of material conditions and substantial generation of the body. A similar problem for human beings arises in nutrition and growth once this process is taken to be some kind of substantial change, namely, the corruption of food and the production of new parts of the living being. Two accounts can be distinguished: “transmateriation” of the matter of food into the nourished body and generation of parts of the body. (shrink)

Galen of Pergamum developed a new notion of the vegetative soul as seated in the liver, in a synthetic appropriation of Platonic tripartition, Aristotelian hylomorphism, Hippocratic elemental theory and Hellenistic science. The traditional analogy between plant and human being receives a firmer grounding in Galen, making the model of the plant more prominent than ever in the discussion of the vegetative soul. While most of the particular functions of the vegetative soul in human beings are well-defined by (...) Galen, its generative and formative powers remain unexplained, since the stuff to which we attribute these powers seems to lack intelligence. (shrink)

Access to fruits and vegetables by low-income residents living in selected urban and rural Minnesotan communities was investigated. Communities were selected based on higher than state average poverty rates, limited access to grocery stores, and urban influence codes (USDA ERS codes). Four communities, two urban and two rural, were selected. Data were gathered from focus group discussions (n = 41), responses to a consumer survey (n = 396 in urban neighborhoods and n = 400 in rural communities), and an inventory (...) of foodstuffs available at stores located in all the communities and at large grocery stores in neighborhoods adjacent to the urban communities. In the two urban neighborhoods, a significant number of foods (26% and 52%) were significantly more expensive than the Thrifty Food Plan’s (TFP) market basket price (MBP). Additionally, a significant number of foods in the two rural communities were more expensive (11% and 26%). In focus groups, participants identified major barriers to shopping in their community to be cost, quality of food, and food choice limitations. Results of the food inventory show that foods within the communities were costly, of fair or poor quality, and limited in number and type available, supporting complaints verbalized by focus group participants. Through focus groups and surveys, participants expressed concern that healthy food choices were not affordable within their communities and believed that people in their community suffered from food insecurity. The absence of quality, affordable food for low-income residents in these four Minnesota communities prevents or diminishes their ability to choose foods that help maintain a healthy lifestyle.

The present investigation studies buying and selling encounters in a Mexican fruit and vegetable shop. It is a conversation-analytic study that shows aspects of the institutional character of these interactions, their overall organisation and sequential structure. It suggests that the core sequential structure of these encounters consists of two base adjacency pairs, buying and selling. In particular, the analysis describes the preparatory characteristics of the pre-expansions that precede the product request formulations, the linguistic composition and sequential positioning of request formulations, (...) the insertions of the buying adjacency pair and the sequencing of the commercial exchange which is described as the climax of the institutional event. The designs of the first pair part of the selling adjacency pair and the product request formulations are presented as clear instances of the referential framework or common ground shared by seller and customer.

This article investigates the emotional undercurrents of Tove Jansson’s Moominvalley in November. I argue that one of the main characters of Jansson’s book is the autumn forest that surrounds the abandoned Moomin house. The decomposing forest is not just an emblem of the inner lives of the guests that gather in the house but is an active character itself: an ambiguous life form that creeps in the house and must be expelled from its living core. I further demonstrate that the (...) emotion of disgust has a crucial role in Jansson’s narrative, and that an adequate analysis of the intentional content of disgust allows us to see what is at issue in the relations between the characters. In my reading, the main insight of Tove Jansson’s last Moomin book is not about loss or sorrow but is about the human capacity to begin anew by composing novel wholes from scraps. (shrink)

The spatial aggregation/dispersion of the vegetation in a landscape affects landscape texture, with potentially important implications for its perception. The aim of the study was to investigate how plant dispersion and interspersion in small-scale landscapes could affect garden preference. Dispersion referred to the proximity and distance between plants, and interspersion referred to the degree of intermixing between plants of different species. Fifty-six participants evaluated 40 pairs of landscapes that differed in terms of plant dispersion or plant interspersion. Participants were asked (...) to rate their preference for each pair of landscapes. Furthermore, eye movements were recorded during the viewing time, and the number of fixations and fixation time were computed for each landscape image. Overall, plants arranged in a more dispersed and a more interspersed design resulted in a higher landscape preference. Dispersion was more effective than interspersion in affecting landscape preference. The number of fixations and fixation time were higher when viewing landscapes with plants arranged in a high-dispersion and high-interspersion layout. (shrink)

In recent years, a great deal of evidence has accumulated on the health risks and environmental impacts of some herbicides. Both conventional agriculture and agroecology are searching for alternatives to address the challenges posed by the consequences of herbicide use. In this search, peasant and indigenous agroecosystems have much to contribute since their crops evolved thousands of years ago together with diverse communities of weeds, and farmers have carried out sophisticated strategies to manage them. Through participant observation, semi-structured interviews, free (...) lists, and botanical collection, we document a milpa design that integrates and manages spontaneous vegetation to take advantage of its presence and minimize risks of crop loss. The objective of this article is to critically contrast agroecological mechanisms in this milpa design which matches the prevention principle with a set of recommendations recognized as preventive in conventional weed science.

Technologies and services provided to resource-poor farmers need to be relevant and compatible with the context in which they operate. This paper examines the contribution of extension services to the food security of resource-poor farmers in a rural village in South Africa. It considers these in terms of the local context and the production of African vegetables in household food plots. A mixture of participatory, qualitative and quantitative research tools, including a household survey, is used to argue that local production (...) practices contribute more to food security requirements than the extension services. This is because of the ability of African vegetables to grow relatively well in semi-arid areas where other exotic plants do not, their ability to provide at least two foodstuffs during their life cycle, and the ability of either the fruit or the leaves, or both, to be dried and stored for consumption in the winter months. These crops can make a significant contribution in terms of household food security, but a number of social and agroecological factors are constraining their production and placing their availability under threat. Despite this, the extension services remain focused on certain activities within vegetable garden projects, even when these are not meeting their proposed purpose—food security by means of cash-crop production. The paper concludes that social and agroecological constraints could be improved if the extension services were changed. This could include the use of context specific and low-cost technologies to ensure that these crops are able to increase their contribution to household food security for resource-poor farmers in semi-arid areas.

This essay pursues the question of vegetal respiration in Presocratics’ doctrines in contrast to Aristotle’s categorical circumscription of this vital process to the blooded animals.

It also discusses plants’ respiration in relation to their body temperature in Menestor, then, concludes by analyzing Democritus’ psychological doctrine, arguing that the intake of fiery atoms pertained to all living (...) beings, plants included.
