In this article, I argue that the French philosopher René Descartes was far more involved in the study of plants than has been generally recognized. We know that he did not include a botanical section in his natural philosophy, and sometimes he differentiated between plants and living bodies. His position was, moreover, characterized by a methodological rejection of the catalogues of plants. However, this paper reveals a significant trend in Descartes's naturalistic pursuits, starting from the end of 1637, whereby he (...) became increasingly interested in plants. I explore this shift by examining both Descartes's correspondence and several notes contained in theExcerpta anatomica. Grounded in direct observations, Descartes's work on vegetation provides a modest, though not unimportant, contribution to a natural-philosophical approach to the vegetal realm. This had a direct bearing on his lifelong ambition to explain the nature of living bodies and also fuelled the emergence of botany as a modern science. (shrink)

In the history of ideas, innumerable attempts to explain life and to define living activities have invoked the notion of the soul. Yet this theoretical entity seems to be an unfathomable thing. Difficulties beset the mere definition of it, and controversies span from whether the soul is a material body or an immaterial form, an immortal or a mortal thing, a subject of experiential or of theoretical knowledge, to the question of whether it is the subject of a specific discipline (...) or rather of a scientia de anima that, in the Aristotelian tradition, was also regarded as a part of natural philosophy—the field of philosophy that deals with natural particulars. Not only was the soul thought, from a theological angle, to define the unity and unicity of living beings, but it was also seen as the source of several bodily activities such as nutrition and growth in living beings. And since some of the beings that grow and nourish themselves also sense and think, the relation of the origin of vegetative powers to the origin of perceptual and intellectual powers has always been an object of debate. In this sense, the soul has not just been a topic of one specific field, but has rather drawn upon many disciplines, combining the work of philosophers, religious thinkers, physicians, naturalists, chymists, and so on, thereby blurring the boundaries between different fields of knowledge. Botanical treatises of the Renaissance, for example, begin with the definition of the soul of plants and its primary role in bringing forth vegetal activities. Indeed, the presence of the soul was thought to be involved also in the life of animals, human beings, and, in some cases, it was even ascribed to minerals and stones, not to speak of the world-soul, the latent idea that the entire cosmos is animated with a soul. Furthermore, the theory of the materiality of the soul was developed since Antiquity and found new momentum in early modern times, in the reappraisal of Epicurean ideas by thinkers such as Guillaume Lamy, Pierre Gassendi, and Julian Offray de La Mettrie. Yet, with the Cartesian Henricus Regius, the understanding of vegetative, sensitive, and rational souls as material importantly surfaces as a peculiar attempt to mechanize the living functions of bodies.

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 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.

In René Descartes' works there are four major references to living bodies as objects of his natural philosophy. The first is contained in the Fifth part of the Discours de la Méthode, published in June 1637, where Descartes provides a mechanical explanation of the heartbeat and other living functions of the body. The second is in a bio-medical note collected in the Excerpta anatomica dated November 1637, where he discusses nutrition and growth. The third is the famous claim on the (...) absence of a section on living bodies in the Principia philosophiae, published in 1644. The fourth is in La Description du corps humain, Descartes' late physiology likely dated 1647-1648. In this article, by exploring these passages and contextualizing his physiological observations of animals and plants, I reassemble Descartes' science of life: his dismissal of soul, his mechanical framework, his interpretation of bodily self-maintenance and growth, his understanding of living bodies as integrated and organic systems, and the role of a power such as the immutatio and forces such as the impetus.

This volume provides a more exhaustive interpretation of Rene Descartes' medical views and its reception in the seventeenth century. Filling the gap in the recent scholarship, the contributions in the volume follow four axes: exegetical, textual, philosophical, and contextual. Authors in this book deal with Descartes' physiology, anatomy, and therapy by reconstructing Cartesian texts, detailing possible medical and philosophical sources, discussing medical collaborations and oppositions, and exploring obscurities and failures in Descartes' medicine. In laying bare the more promising issues of (...) Cartesian programme and discussing the reception and opposition in the seventeenth century, the volume also uncovers the limitations within his interpretation, ultimately revealing a more nuanced application of his methodology to a field of natural philosophy. While medical studies play a not secondary role in Descartes' entire work, the volume aims to discuss in detail the importance of medicine as a suitable field to understand Cartesian philosophy from a significant perspective in seventeenth-century Europe.

Early modern study of plants blossomed in a network of observation, exchanges, collaborations, and epistolary discussions. Following Baconian methodology, Dutch scholars combined the labor of listing and describing plants with botanical experimentation. This empirical approach was a suitable context for Descartes, who exchanged information and performed observations on plants in collaboration with Dutch experimenters. In this article, I focus on (1) the reception of a few botanical experiments of Bacon’s Sylva Sylvarum in Huygens and Reneri, with whom Descartes was in (...) contact, and (2) Descartes’ collaboration with Reneri. While performing observations on plants together, Reneri acquired Descartes’ theoretical framework (as it arises in his disputations) and influenced the latter with a Baconian approach to the study of living nature. This combination of experimental knowledge and a theoretical framework shaped a Cartesian study of plants, as it later surfaced in Regius and ultimately paved the way to a modern science of plants.

In a recent poem, Vom Schnee, oder Descartes in Deutschland, German writer Durs Grünbein suggests that a snowy, white landscape inspired the young René Descartes to theoretically define nature. Indeed, Descartes's reduction of nature to extended matter composed of particles in movement and abiding by the laws of nature entails a reduction of all bodies' diversity to a mechanistic system in which all secondary qualities are mathematically framed. The description of colors in the Regulae ad directionem ingenii exemplifies this reduction (...) of nature to a geometrical grid with no differences—Jean-Luc Marion (Sur... (shrink)

René Descartes’ mechanization of living activities lays bare a glaring lacuna that concerns vegetative functions, such as nutrition, generation, and growth: his cardiovascular framework affects any exhaustive explanation of these activities. When he mentions a mechanical vegetative power in his 1641 correspondence with Henricus Regius, this definition is unspecified, although it may be correlated to a few posthumous bio-medical notes. Descartes’ mechanization of the vegetative soul remains puzzling. Early Cartesian scholars were thus obliged to fill this lacuna to produce a (...) more exhaustive physiology. In this chapter, after reconstructing Descartes’ own position in L’Homme and in his manuscripts, I explore the positions of Regius, Louis de La Forge, and Florent Schuyl, who dealt with Descartes’ medical texts and physiological doctrine through various perspectives. Yet, while building a mechanization of vegetation upon Descartes’ philosophy, their interpretations of a mechanical vegetative power uncover shortcomings, weaknesses, and failures. (shrink)

This book explores René Descartes’s attempts to describe particular bodies, such as rocks, minerals, metals, plants, and animals, within the mechanistic interpretation of nature of his philosophical program. Despite his early rationalistic epistemology, Descartes’s increasing attention to collections, histories, lists of qualities, and particular bodies results in a puzzling ‘short history of all natural phenomena’ contained in the Principles of philosophy (1644). The present book outlines the role of Descartes's observations and experimentation as he aimed to construct a universal science (...) of nature, ultimately revealing the mechanization of nature in detail, and for curious bodies such as the Bologna Stone or the sensitive herb. What results is a theoretical natural history consistent with the mechanical principles of his philosophy, ultimately shedding new light on his attempt to produce a complete philosophy of nature.

In this paper, we use concepts, structure and tools from argumentation theory to show how conversational implicatures are triggered by conflicts of presumptions. Presumptive implicatures are shown to be based on defeasible forms of inference used in conditions of lack of knowledge, including analogical reasoning, inference to the best explanation, practical reasoning, appeal to pity, and argument from cause. Such inferences are modelled as communicative strategies to knowledge gaps that shift the burden of providing the missing contrary evidence to the (...) other party in a dialogue. Through a series of illustrative examples, we show how such principles of inference are based on common knowledge about the ordinary course of events shared by participants in a structured dialogue setting in which they take turns putting forward and responding to speech acts.

The purpose of this paper is to provide a basis for a systematic development of signaling theory on CSR initiatives. The paper proposes signaling theory as a framework supportive of a strategic CSR approach; maps extant research on signaling through CSR initiatives; offers a comprehensive assessment of the most diffused CSR initiatives and discusses their eligibility as signaling devices; and outlines a research agenda to further develop and test signaling theory in business ethics. Specifically, the study reconsiders some key assumptions, (...) identifies key gaps in empirical validation, and proposes directions to extend multiple signal, signaling pattern, and target cases.

This paper builds a nine-step method for determining whether a straw man fallacy has been committed in a given case or not, by starting with some relatively easy textbook cases and moving to more realistic and harder cases. The paper shows how the type of argument associated with the fallacy can be proved to be a fallacy in a normative argumentation model, and then moves on to the practical task of building a hands-on method for applying the model to real (...) examples of argumentation. Insights from linguistic pragmatics are used to distinguish the different pragmatic processes involved in reconstructing what is said and what is meant by an utterance, and to differentiate strong and weak commitments. In particular, the process of interpretation is analyzed in terms of an abductive pattern of reasoning, based on co-textual and contextual information, and assessable through the instruments of argumentation theory.

Pragmatic presuppositions are analyzed considering their relation with the notion of commitment, namely the dialogical acceptance of a proposition by an interlocutor. The attribution of commitments carried out by means of pragmatic presupposition is shown to depend on the reasonableness of the underlying presumptive reasoning, ultimately grounded on hierarchies of presumptions. On this perspective, the ordinary interpretation of pragmatic presuppositions as the “taking for granted” of propositions signaled by semantic or syntactic triggers becomes only the presumptive, prototypical interpretation of a (...) complex linguistic and pragmatic phenomenon. It will be shown how the prototypical interpretation is subject to default in cases of conflicts of presumptions, which lead to reconstructing the speaker’s meaning non-presumptively at a pragmatic, semantic, or syntactic level. The phenomena of presupposition cancellation and neutralization can be explained in terms of presumptive and non-presumptive articulation and interpretation of an utterance, through which the speaker can impose, correct, or refuse implicit commitments.

The analysis of multimodal argumentation in advertising is a crucial and problematic area of research. While its importance is growing in a time characterized by images and pictorial messages, the methods used for interpreting and reconstructing the structure of arguments expressed through verbal and visual means capture only isolated dimensions of this complex phenomenon. This paper intends to propose and illustrate a methodology for the reconstruction and analysis of “double-mode” arguments in advertisements, combining the instruments developed in social semiotics, pragmatics, (...) and argumentation theory. An advertisement is processed through a five-step path. The analysis of its context, text genre, and images leads to a first representation of the messages that it encodes both pictorially and verbally (step 1). These first semantic representations are further enriched by including their polyphonic articulations and presuppositions (step 2), their explicatures (step 3), and their dialogical functions and illocutionary forces (step 4). These pragmatic steps retrieve the commitment structure of the ad, which allows a further argument analysis conducted through argumentation schemes (step 5). (shrink)

Argument from analogy is a common and formidable form of reasoning in law and in everyday conversation. Although there is substantial literature on the subject, according to a recent survey ( Juthe 2005) there is little fundamental agreement on what form the argument should take, or on how it should be evaluated. Th e lack of conformity, no doubt, stems from the complexity and multiplicity of forms taken by arguments that fall under the umbrella of analogical reasoning in argumentation, dialectical (...) studies, and law. Modeling arguments with argumentation schemes has proven useful in attempts to refine the analyst’s understanding of not only the logical structures that shape the backbone of the argument itself, but also the logical underpinning of strategies for evaluating it, strategies based on the semantic categories of genus and relevance. By clarifying the distinction between argument from example and argument from analogy, it is possible to advance a useful proposal for the treatment of argument from analogy in law. (shrink)

Subjekt, Objekt und Intersubjektivitat bilden drei der wohl zentralsten Elemente im menschlichen Erkenntnisprozess. Anhand einer kritischen Rekonstruktion der Erkenntnistheorien Hegels und Adornos beleuchtet die vorliegende Arbeit die Dialektik zwischen Subjekt und Objekt der Erkenntnis aus zwei verschiedenen Perspektiven. Durch den grundsatzlichen Paradigmenwechsel Habermas' von der Bewusstseinsphilosophie zu einem kommunikationstheoretischen Paradigma wird es moglich, <I>kommunikative Intersubjektivitat als unverzichtbares Element der Erkenntnis angemessen zu thematisieren.<BR> Der Gang von Hegel uber Adorno zu Habermas wird in der vorliegenden Monographie nicht als ein stetiger Fortschritt (...) verstanden, an dessen Zielpunkt die Habermas'sche Theorie als der Weisheit letzter Schluss stehen wurde. Vielmehr erweist sich der Dreischritt selbst als ein dialektischer, der am Ende, angereichert durch Erfahrungen, wieder in seinen Ausgangspunkt mundet. So endet die Untersuchung letztlich mit dem kommunikationstheoretisch angereicherten Desiderat einer modernen Subjekttheorie.". (shrink)
