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)

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)

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 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.

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.

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.

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.

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)

This paper is a guide to the main ideas and innovations in Robert Stalnaker's "Indicative Conditionals". The paper is for a volume of essays on twenty-one classics of formal semantics edited by Louise McNally and Zoltàn Gendler Szabò.

This paper motivates and develops a novel semantic framework for deontic modals. The framework is designed to shed light on two things: the relationship between deontic modals and substantive theories of practical rationality and the interaction of deontic modals with conditionals, epistemic modals and probability operators. I argue that, in order to model inferential connections between deontic modals and probability operators, we need more structure than is provided by classical intensional theories. In particular, we need probabilistic structure that interacts directly (...) with the compositional semantics of deontic modals. However, I reject theories that provide this probabilistic structure by claiming that the semantics of deontic modals is linked to the Bayesian notion of expectation. I offer a probabilistic premise semantics that explains all the data that create trouble for the rival theories. (shrink)

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.

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.

Possibility semantics offers an elegant framework for a semantic analysis of modal logic that does not recruit fully determinate entities such as possible worlds. The present papers considers the application of possibility semantics to the modeling of the indeterminacy of the future. Interesting theoretical problems arise in connection to the addition of object-language determinacy operator. We argue that adding a two-dimensional layer to possibility semantics can help solve these problems. The resulting system assigns to the two-dimensional determinacy operator a well-known (...) logic (coinciding with the logic of universal modalities under global consequence). The paper concludes with some preliminary inroads into the question of how to distinguish two-dimensional possibility semantics from the more established branching framework. (shrink)

I motivate and characterize an intensional semantics for ‘ought’ on which it does not behave as a universal quantifier over possibilities. My motivational argument centers on taking at face value some standard challenges to the quantificational semantics, especially to the idea that ‘ought’-sentences satisfy the principle of Inheritance. I argue that standard pragmatic approaches to these puzzles are either not sufficiently detailed or unconvincing.

Modus ponens is the argument from premises of the form If A, then B and A to the conclusion B. Nearly all participants agree that the modus ponens conclusion logically follows when the argument appears in this Basic form. However, adding a further premise can lower participants’ rate of agreement—an effect called suppression. We propose a theory of suppression that draws on contemporary ideas about conditional sentences in linguistics and philosophy. Semantically, the theory assumes that people interpret an indicative conditional (...) as a context-sensitive strict conditional: true if and only if its consequent is true in each of a contextually determined set of situations in which its antecedent is true. Pragmatically, the theory claims that context changes in response to new assertions, including new conditional premises. Thus, the conclusion of a modus ponens argument may no longer be accepted in the changed context. Psychologically, the theory describes people as capable of reasoning about broad classes of possible situations, ordered by typicality, without having to reason about individual possible worlds. The theory accounts for the main suppression phenomena, and it generates some novel predictions that new experiments confirm. (shrink)

We discuss the semantic significance of a puzzle concerning ‘ought’ and conditionals recently discussed by Kolodny and MacFarlane. We argue that the puzzle is problematic for the standard Kratzer-style analysis of modality. In Kratzer’s semantics, modals are evaluated relative to a pair of conversational backgrounds. We show that there is no sensible way of assigning values to these conversational backgrounds so as to derive all of the intuitions in Kolodny and MacFarlane’s case. We show that the appropriate verdicts can be (...) derived by extending Kratzer’s framework to feature a third conversational background and claiming that the relevant reading of ‘ought’ is sensitive to this parameter.

Provisional draft, pre-production copy of my book “The Modal Future” (forthcoming with Cambridge University Press).

A long-standing tension in semantic theory concerns the reconciliation of positive gradable adjective (GA) ascriptions and comparative GA ascriptions. Vagueness-based ap- proaches derive the comparative from the positive, and face non-trivial challenges with incommensurability and non-GA comparatives. Classic degree-based approaches effectively derive the positive from the comparative, out of sync with the direction of evidence from morphology, and create some difficulties in accounting for GA scale-mates with differing thresholds (e.g., cold ∼ warm ∼ hot). We propose a new reconciliation that (...) capitalizes on recent proposals analyzing GAs as predicates of states. On our account, GAs lexically involve both a threshold property and a background state structure. Positive occurrences of GAs make use of the threshold property, while comparative occurrences make use of degrees representing elements of the background structure. Our approach preserves the virtues of classic degree-based approaches while offering a natural account of scale-mates, and without appeal to covert morphemes like POS or related devices. As we show, it is possible to inject our solution back into the classic degree-based approach, but we find reasons to prefer our states-based account. (shrink)

Statements about the future are central in everyday conversation and reasoning. How should we understand their meaning? The received view among philosophers treats will as a tense: in ‘Cynthia will pass her exam’, will shifts the reference time forward. Linguists, however, have produced substantial evidence for the view that will is a modal, on a par with must and would. The different accounts are designed to satisfy different theoretical constraints, apparently pulling in opposite directions. We show that these constraints are (...) jointly satisfied by a novel modal account of will. On this account, will is a modal but doesn't work as a quantifier over worlds. Rather, the meaning of will involves a selection function similar to the one used by Stalnaker in his semantics for conditionals. The resulting theory yields a plausible semantics and logic for will and vindicates our intuitive views about the attitudes that rational agents should have towards future-directed contents.

I propose an account of the speech act of prediction that denies that the contents of prediction must be about the future and illuminates the relation between prediction and assertion. My account is a synthesis of two ideas: (i) that what is in the future in prediction is the time of discovery and (ii) that, as Benton and Turri recently argued, prediction is best characterized in terms of its constitutive norms.

This paper explores two non-standard supermajority rules in the context of judgment aggregation over multiple logically connected issues. These rules set the supermajority threshold in a local, context sensitive way—partly as a function of the input profile of opinions. To motivate the interest of these rules, I prove two results. First, I characterize each rule in terms of a condition I call ‘Block Preservation’. Block preservation says that if a majority of group members accept a judgment set, then so should (...) the group. Second, I show that one of these rules is, in a precise sense, a judgment aggregation analogue of a rule for connecting qualitative and quantitative belief that has been recently defended by Hannes Leitgeb. The structural analogy is due to the fact that Leitgeb sets thresholds for qualitative beliefs in a local, context sensitive way—partly as a function of the given credence function. (shrink)

Conditional perfection is the phenomenon in which conditionals are strengthened to biconditionals. In some contexts, “If A, B” is understood as if it meant “A if and only if B.” We present and discuss a series of experiments designed to test one of the most promising pragmatic accounts of conditional perfection. This is the idea that conditional perfection is a form of exhaustification—that is a strengthening to an exhaustive reading, triggered by a question that the conditional answers. If a speaker (...) is asked how B comes about, then the answer “If A, B” is interpreted exhaustively to meaning that A is the only way to bring about B. Hence, “A if and only if B.” We uncover evidence that conditional perfection is a form of exhaustification, but not that it is triggered by a relationship to a salient question. (shrink)

We advocate and develop a states-based semantics for both nominal and adjectival confidence reports, as in "Ann is confident/has confidence that it's raining", and their comparatives "Ann is more confident/has more confidence that it's raining than that it's snowing". Other examples of adjectives that can report confidence include "sure" and "certain". Our account adapts Wellwood's account of adjectival comparatives in which the adjectives denote properties of states, and measure functions are introduced compositionally. We further explore the prospects of applying these (...) tools to the semantics of probability operators. We emphasize three desirable and novel features of our semantics: (i) probability claims only exploit qualitative resources unless there is explicit compositional pressure for quantitative resources; (ii) the semantics applies to both probabilistic adjectives (e.g., "likely") and probabilistic nouns (e.g., "probability"); (iii) the semantics can be combined with an account of belief reports that allows thinkers to have incoherent probabilistic beliefs (e.g. thinking that A & B is more likely than A) even while validating the relevant purely probabilistic claims (e.g. validating the claim that A & B is never more likely than A). Finally, we explore the interaction between confidence-reporting discourse (e.g., "I am confident that...") and belief-reports about probabilistic discourse (e.g.,"I think it's likely that..").

Semantic perceptualism is the thesis that meaning experiences are forms of perceptual experiences. According to its defenders, this view is motivated not only by philosophical considerations, but also by empirical evidence. In the present article, I shall provide the first comprehensive and critical review of the empirical evidence in support of semantic perceptualism, including a detailed analysis of the relevant neuroanatomical data. The conclusions of my analysis are largely pessimistic. I believe that the relevant behavioral, cognitive, and patient data are (...) suggestive but hardly conclusive. Moreover, neuroanatomical data speak strongly against semantic perceptualism. (shrink)
