Recent epistemology has focused almost exclusively on propositional knowledge. This paper considers an underexplored area of epistemology, namely knowledge of persons: if propositional knowledge is a state of mind, consisting in a subject's attitude to a (true) proposition, the account developed here thinks of interpersonal knowledge as a state of minds, involving a subject's attitude to another (existing) subject. This kind of knowledge is distinct from propositional knowledge, but it exhibits a gradability characteristic of context-sensitivity, and admits of shifty thresholds. (...) It is supported by a wide range of unexplored linguistic data and intuitive cases; and it promises to illuminate debates within epistemology, philosophy of religion, and ethics. (shrink)

Kant is often considered to have argued that perceptual awareness of objects in one's environment depends on the subject's possession of conceptual capacities. This conceptualist interpretation raises an immediate problem concerning the nature of perceptual awareness in non-rational, non-concept using animals. In this paper I argue that Kant’s claims concerning animal representation and consciousness do not foreclose the possibility of attributing to animals the capacity for objective perceptual consciousness, and that a non-conceptualist interpretation of Kant’s position concerning perceptual awareness can (...) actively endorse this attribution. Kant can consistently allow that animals have a point of view on the objective world which possesses a distinctive phenomenal character while denying what seems most important to him – viz. that animals have the capacity to take cognitive attitudes towards, and thus self-ascribe, their own representational states.

Empirical discussions of mental representation appeal to a wide variety of representational kinds. Some of these kinds, such as the sentential representations underlying language use and the pictorial representations of visual imagery, are thoroughly familiar to philosophers. Others have received almost no philosophical attention at all. Included in this latter category are analogue magnitude representations, which enable a wide range of organisms to primitively represent spatial, temporal, numerical, and related magnitudes. This article aims to introduce analogue magnitude representations to a (...) philosophical audience by rehearsing empirical evidence for their existence and analysing their format, their content, and the computations they support. 1 Background1.1 Evidence of analogue magnitude representations1.2 Weber’s law1.3 Scepticism about analogue magnitude representations2 Format2.1 Carey’s analogy2.2 Neural realization2.3 Analogue representation2.4 Analogue magnitude representation components3 Content3.1 Do analogue magnitude representations have representational content?3.2 What do analogue magnitude representations represent?3.3 What content types do analogue magnitude representations have?4 Computations4.1 Arithmetic computation4.2 Practical deliberation5 Conclusion.

I argue that we can reconcile two seemingly incompatible traditions for thinking about concepts. On the one hand, many cognitive scientists assume that the systematic redeployment of representational abilities suffices for having concepts. On the other hand, a long philosophical tradition maintains that language is necessary for genuinely conceptual thought. I argue that on a theoretically useful and empirically plausible concept of 'concept', it is necessary and sufficient for conceptual thought that a thinker be able to entertain many of the (...) potential thoughts produced by recombining her representational abilities apart from a direct confrontation with the states of affairs being represented. Such representational abilities support a cognitive engagement with the world that is flexible, abstract, and active. (shrink)

In this paper I will argue that the gender properties expressed by human voices are part of auditory phenomenology. I will support this claim by investigating auditory adaptational effects on such properties and contrasting auditory experiences, before and after the adaptational effects take place. In light of this investigation, I will conclude that auditory experience is not limited to low-level properties. Perception appears to be much more informative about the auditory landscape than is commonly thought.

This paper contrasts three different schemes of reference relevant to understanding systems of perceptual representation: a location-based system dubbed "feature-placing", a system of "visual indices" referring to things called "proto-objects", and the full sortal-based individuation allowed by a natural language. The first three sections summarize some of the key arguments (in Clark, 2000) to the effect that the early, parallel, and pre-attentive registration of sensory features itself constitutes a simple system of nonconceptual mental representation. In particular, feature integration--perceiving something as (...) being both F and G, where F and G are sensible properties registered in distinct parallel streams--requires a referential apparatus. Section V. reviews some grounds for thinking that at these earliest levels this apparatus is location-based: that it has a direct and nonconceptual means of picking out places. Feature-placing is contrasted with a somewhat more sophisticated system that can identify and track four or five "perceptual objects" or "proto-objects", independently of their location, for as long as they remain perceptible. Such a system is found in Zenon Pylyshyn's fascinating work on "visual indices", in Dana Ballard's notion of deictic codes, and in Kahneman, Treisman, and Wolfe's accounts of systems of evanescent representations they call "object files". Perceptual representation is a layered affair, and I argue that it probably includes both feature-placing and proto-objects. Finally, both nonconceptual systems are contrasted with the full-blooded individuation allowed in a natural language. (shrink)

In considering the possibility that the fundamental particles of matter might violate Leibniz's Principle, one is confronted with logical proofs that the Principle is a Theorem of Logic. This paper shows that the proof of that theorem is not universal enough to encompass entities that might not be unique, and also strongly suggests that photons, for example, do violate Leibniz's Principle. It also shows that the existence of non-individuals would imply the breakdown of Quine's criterion of ontological commitment.

Philosophers of mind have not in general been very attentive to metaphysics. This book is a salutary exception to this general observation. A philosopher of mind—at least the body of her very influential work would be classified by most philosophers as belonging to the philosophy of mind—attempts to ground a theory of the relation between human persons and their bodies in an extended essay on the metaphysics of the natural world. Baker is a materialist : in her book, you and (...) I and everyone we know is a material thing. But then how are we material persons related to our bodies, which are also material things? Unlike many materialists, she rejects the following answer to this question: We are identical with our bodies. The bulk of this review is no more than a summary of her answer to the “person-body question.” My summary will use language very different from hers, since it will rely heavily on the language of parthood, and she is extremely hostile to any attempt to use the concept “part” in connection with her theory. Nevertheless, the use I make of this concept is innocuous, and my representation of her answer to the person-body question is accurate. (shrink)

In what sense does empty space feature in visual experience? In the first part of this essay I sketch a view advanced by Soteriou and Richardson on which one's visual awareness of empty space is explained by appeal to ‘structural’ features of the phenomenology of visual experience, in particular the phenomenology of experiencing one's visual field as bounded. I suggest that although this ‘structuralist’ view is silent on whether empty space has a phenomenal appearance, the very appeal to structural features (...) seems a natural foil to some such thought. In the second part, I outline a view on which it can be granted that empty space does, after all, have a phenomenal appearance and, so, is not best cast as a species of absence perception as the structuralist avows, at least on a certain construal of ‘absence perception’. After O'Shaughnessy , I contend that although some privations have a phenomenal appearance, ‘absence perception’ should single out the putative perception of phenomena that lack phenomenal reality. I finally consider how the descriptive phenomenology that the structuralist points to, and which I urge should be embraced, can nonetheless be reconciled with the view I spell out. (shrink)

There is a fairly general consensus that names are Millian (or Russellian) genuine terms, that is, are singular terms whose sole semantic function is to introduce a referent into the propositions expressed by sentences containing the term. This answers the question as to what sort of proposition is expressed by use of sentences containing names. But there is a second serious semantic problem about proper names, that of how the referents of proper names are determined. This is the question that (...) I will discuss in this paper. Various views consistent with Millianism have been proposed as to how the semantic referents of proper names are determined. These views can be classified into (1) description theories and (2) causal theories, but they can also be classified into (3) social practice theories, on which a name’s referent is determined by a social practice involving the referent, and (4) individualistic theories, on which the referent of the use of a name is determined by the speaker’s state of mind. Here I argue against social practice theories of the sorts proposed by Kripke and Evans and in favor of an individualistic approach to name reference. I argue that social practice is irrelevant to determining name reference and that, as a consequence, names have no meanings in natural languages. In the second part of the paper I motivate and propose a new form of individualistic theory which incorporates features of both description theories and Evans’s social practice theory. (shrink)

In “Naming and Necessity” Saul Kripke describes some cases which, he claims, provide counterexamples both to cluster theories and, more generally, to description theories of proper names. My view of these cases is that while they do not provide counterexamples to cluster theories, they can be used to provide evidence against single-description theories. In this paper I shall defend both of the claims involved in my view.

Many have held that when a person visually attends to an object, her visual system deploys a representation that designates the object. Call the referential link between such representations and the objects they designate attentive visual reference. In this article I offer an account of attentive visual reference. I argue that the object representations deployed in visual attention—which I call attentive visual object representations —refer directly, and are akin to indexicals. Then I turn to the issue of how the reference (...) of an AVOR is determined relative to a context. After raising problems for existing accounts, I propose a mechanism of reference determination that is both causal and descriptive: For an AVOR to refer to a particular object, the object must appropriately cause the deployment of the AVOR, and the AVOR must be associated with descriptive information about some of the object's geometrical and mereological properties.

In the ongoing ‘brain death’ controversy, there has been a constant push for the use of the ‘higher brain’ formulation as the criterion for the determination of death on the grounds that brain-dead individuals are no longer human beings because of their irreversible loss of consciousness and mental functions. This essay demonstrates that such a position flows from a Lockean view of human persons. Compared to the ‘consciousness-related definition of death,’ the substance view is superior, especially because it provides a (...) holistic vision of the human person, and coheres with the perennial axiom about the ‘whole and parts.’.

This article describes some of the main arguments for the existence of other minds, and intersubjectivity more generally, that depend upon a transcendental justification. This means that our focus will be largely on ‘continental’ philosophy, not only because of the abiding interest in this tradition in thematising intersubjectivity, but also because transcendental reasoning is close to ubiquitous in continental philosophy. Neither point holds for analytic philosophy. As such, this essay will introduce some of the important contributions of Edmund Husserl, Martin (...) Heidegger, Jean-Paul Sartre, Maurice Merleau-Ponty and Karl-Otto Apel, all of whom use transcendental reasoning as a key part of their analyses of intersubjectivity, and we also consider the work of Peter Strawson who does likewise in the analytic tradition.

There is an unresolved stand-off between ontological naturalism and phenomenological thought regarding the question whether normativity can be reduced to physical entities. While the ontological naturalist line of thought is well established in analytic philosophy, the phenomenological reasoning for the irreducibility of normativity has been largely left ignored by proponents of naturalism. Drawing on the work of Husserl, Heidegger, Schütz, Stein and others, I reconstruct a phenomenological argument according to which natural science (as the foundation of naturalization projects) is itself (...) a part of the essentially normative life-world to the effect that ontological naturalism faces a bootstrapping problem. I aim to demonstrate that this stand-off is grounded in a deep disagreement about the possibility of reduction. I close by arguing that this deep disagreement turns on the question which conception about the nature of (natural) science is true. This result pits a perfectionist model of science (implied by ontological naturalism) against a pragmatist conception of science (in favour of the phenomenological argument). The motivation is that transforming the disagreement about the controversial principle into a disagreement about conceptions of science may help to offer a foundation for different attempts at solving the stand-off.

Brentano’s metaphysical position in Psychology from an Empirical Standpoint is usually assumed to be metaphysical realism. I propose an alternative interpretation, according to which Brentano was at that time, as well as later, a full-fledged phenomenalist. However, his phenomenalism is markedly different from standard phenomenalism in that it does not deny that the physicist’s judgments are really about the objective world. The aim of the theory of intentionality, I argue, is to allow for extra-phenomenal aboutness within a phenomenalist framework.

According to the species-as-individuals thesis(hereafter S-A-I), species are cohesive entities. Barker and Wilson recently pointed out that the type of cohesion exhibited by species is fundamentally different from that of organisms (paradigmatic individuals), suggesting that species are homeostatic property cluster kinds. In this article, I propose a shift in how to approach cohesion in the context of S-A-I: instead of analyzing the different types of cohesion and questioning whether species have them, I focus on the role played by cohesion in (...) the identity of individuals. This shift allows us to recognize why cohesion matters to S-A-I, as well as to reconceive the analogy between species and organisms (paradigmatic individuals), and also allows us to highlight the context sensitivity of both ‘‘cohesion’’ and ‘‘individuals.’’ From this perspective, I identify two problems in Barker and Wilson’s argumentation. Firstly, the authors fail to recognize that species are individuals even if they do not have the same type of cohesion that organisms have. Secondly, their argument relies on a misinterpretation of S-A-I. I conclude that species cohesion is still best framed as a feature of species individuality rather than a feature of species as homeostatic property cluster kinds. The arguments presented here contribute to the re-articulation and reevaluation of S-A-I in the face of contemporary discussions. (shrink)

Three central theses of A Theory of Sentience are these.

A natural language is an organic living thing; and meanings change as words take on new, and shed old, connotations. Recent philosophy of language has paid little attention to the growth of meaning; radical philosophers like Feyerabend and Rorty have suggested that meaning-change undermines the pretensions of science to be a rational enterprise. Thinkers in the classical pragmatist tradition, however -Peirce in philosophy of science and, more implicitly, Holmes in legal theory- both recognized the significance of growth of meaning, and (...) understood how it can contribute to the progress of science and to the adaptation of a legal system to changing circumstances. This paper develops these insights, and illustrates them by reference to the growth of meaning of "DNA" from the identification of "nuclein" to the discovery of mtDNA almost a century later, and the growth of meaning of "the establishment of religion" in the First Amendment to the U.S. Constitution from its ratification in 1791 to the present day. Arguing that the growth of meaning can indeed contribute to rationality, it also shows why narrowly formal models are inadequate both to science and to law. Un lenguaje natural es una cosa viviente orgánica, y los significados cambian a medida que las palabras adoptan nuevas connotaciones y abandonan viejas. La filosofía del lenguaje reciente ha prestado poca atención al desarrollo del significado; filósofos radicales, como Feyerabend y Rorty han sugerido que el cambio de significado socava las pretensiones de la ciencia de ser una empresa racional. Pensadores en la tradición pragmatista clásica, sin embargo -Peirce en la filosofía de la ciencia y, más implícitamente, Holmes en la teoría del Derecho- reconocieron la importancia del desarrollo del significado y comprendieron cómo éste puede contribuir al progreso de la ciencia y a la adaptabilidad de un sistema jurídico a las circunstancias cambiantes. Este trabajo desarrolla estas ideas, y las ilustra por medio de una referencia a el desarrollo del significado de "ADN" desde la identificación de la "nucleína" hasta el descubrimiento del ADN mitocondrial casi un siglo más tarde, y el desarrollo del significado de "el establecimiento de una religión" en la Primera Enmienda de la Constitución de los Estados Unidos desde su ratificación en 1791 hasta la actualidad. Argumentando que el desarrollo del significado puede contribuir mucho a la racionalidad, también muestra por qué los modelos estrechamente formales son inadecuados, tanto para la ciencia como para el Derecho.

In this essay I distinguish categories of animals by their mental capacities. I then discuss whether punishment can be appropriate for animals of each category, and if so what form punishment may appropriately take for animals of each category. The aim is to illuminate each type of punishment through comparison and contrast with the others. This both forestalls the overintellectualization of punishment which arises from viewing humans as the only paradigm case and forestalls the underintellectualization of human punishment which results (...) from making no essential reference, in an account of human punishment, to the human capacity for specifically critical reasoning.

The subject matter of this thesis is analytic ontology. Chapters II and III deal with two versions of trope theory, or moderate nominalism; these are defined as ontologies which recognise properties and relations but no (real) universals. The key notion of both theories, trope, is characterised as an abstract particular. What the abstractness amounts to differs between the two. Yet another difference is that simplicity is an essential trait of a trope according to one theory, but not according to the (...) other. Though exact similarity is said to play an important role in both theories, as it turns out, this does not seem to be the case. The ontology dealt with in chapter IV is a mixture of moderate nominalism concerning qualities and realism concerning relations. In it, quality instances (moments) and universal relations are the ultimate constituents of the universe. While relations and moments are considered to be constituents of states of affairs, which are characterised as objects of higher orders, complexes that are objects of the first order are made up of moments on their own. Among these complexes one finds the ordinary objects. Paradoxically, although relations are necessary for the existence of complex first order objects, relations are not thought to be among the contents of these objects. The main subject of chapter V is a particular version of moderate realism; it is an ontology which is realistic in its recognition of universals and moderate in its recognition of instances of these universals. Instances combine to form complex networks. A theoretically motivated claim is that although each instance has a predicational aspect as well as a universal one, it is simple in the sense of lacking internal predicative structure; though, this claim can be called into question. Keywords: analytic ontology, moderate nominalism, moderate realism, particular, universal, abstract, concrete, abstract particular, abstract universal, concrete particular, concrete universal, trope, moment, complex unity, collection, instance, unit attribute, intensional aspect, predicational aspect, continuous composite, articulated composite.

Rom Harré's proposed Copernican Revolution in the philosophy of science is a very ambitious undertaking. It challenges established views, proposes a radically new model for scientific explanation, and forces a rethinking of the foundations of the field. In his treatment of the natural sciences, Harré rejects all deductivist accounts of scientific explanation basically on the grounds that such accounts seriously distort the methods of explanation actually operative in science. In the social sciences Harré, in collaboration with Secord, rejects mechanistic, positivistic, (...) and behavioristic accounts of human behavior [5]. In place of these discarded interpretations he substitutes a new realism which stresses the role that models play in supplying accounts of observed patterns of phenomena in terms of the things and processes whose interactions are responsible for the manifest phenomena. This revolution, if successfully carried out, would indeed be a valuable contribution to the philosophy of science. (shrink)

Some philosophers have argued that we do not hear sounds as located in the environment. Others have objected that this straightforwardly contradicts the phenomenology of auditory experience. And from this they draw metaphysical conclusions about the nature of sounds—that they are events or properties of vibrating surfaces rather than waves or sensations. I argue that there is a minimal, but recognizable, notion of audition to which this phenomenal objection does not apply. While this notion doesn’t correspond to our ordinary notion (...) of auditory experience, it does—in conjunction with our lack of an uncontroversial individuation of the senses and recent interest in distinctively multisensory features of perceptual experiences—raise the possibility of more expansive notions of audition, including some that do plausibly count as corresponding to our everyday notion of audition, that lack the spatial phenomenology cited in the objection. Until this possibility is ruled out, the phenomenal objection and metaphysical conclusions drawn from it remain inconclusive. (shrink)

The Linda paradox is a key topic in current debates on the rationality of human reasoning and its limitations. We present a novel analysis of this paradox, based on the notion of verisimilitude as studied in the philosophy of science. The comparison with an alternative analysis based on probabilistic confirmation suggests how to overcome some problems of our account by introducing an adequately defined notion of verisimilitudinarian confirmation.

Everyone agrees that musical works are individuated by essential elements such as tone, harmony, and rhythm. Some argue that timbre or instrumentation can individuate musical works, too. I argue here that there can be a further element of musical works: spatial location. Some works of music are partly constituted by the location and motion of their sound sources. I begin by describing works of spatial music and arguing that they exist. I then consider the implications for the ontology of music. (...) Hardcore formalists cannot allow for spatial music. I argue that two other views, which allow a close relationship between sounds and musical works, can allow for works of spatial music. However, their ability to do so turns on issues in the philosophy of sound. I appeal to work in philosophy of sound to show that music is an art not just of hearing, but of sounds. (shrink)

This discussion note aims to address the two points which Lizza raises regarding my critique of his paper “Defining Death: Beyond Biology,” namely that I mistakenly attribute a Lockean view to his ‘higher brain death’ position and that, with respect to the ‘brain death’ controversy, both the notions of the organism as a whole and somatic integration are unclear and vague. First, it is known from the writings of constitutionalist scholars that the constitution view of human persons, a theory which (...) Lizza also holds, has its roots in John Locke’s thought. Second, contrary to Lizza’s claims, the notions of the organism as a whole and somatic integration are both more than adequately described in the biomedical and biophilosophical literature. (shrink)

John Macmurray (1891-1976) was born in Scotland and began his philosophical education in a Scottish university. As an academic philosopher, following in the footsteps of Caird’s Scottish idealism - a reaction against the debate between Hume’s scepticism and Reid’s ‘commonsense’ – Macmurray holds that a university education in moral philosophy is essential for producing virtuous citizens. Consequently, Macmurray’s philosophy of human nature includes a ‘thick’ description of the person, which is more holistic that Cartesianism and emphasizes the relation of persons. (...) Hence, Macmurray focuses on community, but, as this chapter reveals, he is not a communitarian in the contemporary sense; rather, he shares Caird’s focus on philosophy as the means to living well. Thus, he opposes increasing specialization in university education and highlights the limits of science, which, Davie notes, is representative of the Scottish metaphysic of Macmurray’s era. Macmuray is the last in this line of the Scottish philosophical tradition. (shrink)

This paper takes the first steps in the construction of a theory of event identity as that theory applies to historical sentences. The theory is extensional throughout. Following statements of criteria of adequacy for the construction, Davidson's method of regimenting sentences is adopted in order to allow for variables ranging over events. Events in this theory are only partially construed, that is, to the extent of treating them as concrete individuals rather than as classes or repeatable universals. The paper concludes (...) with a statement of several theorems and definitions and an example of how the theory works. (shrink)

Most theorists treat the ‘relation’ of identity as being more fundamental (or basic) than the ‘relation’ of (numerical) difference. Herbert Hochberg suggests, instead, that difference is to be treated as basic. My goal in this paper is to answer two related questions. First, what is it for a theorist to treat difference or identity as basic? Second, which of these two ‘relations’ is to be treated as basic? I begin by outlining four reasons that one might be motivated to endorse (...) the view that difference is to be treated as basic. Based on these reasons, I distinguish three ways of conceiving of what is involved in treating difference as basic: one conception involves the reification of the relation of difference, whereas the other two do not. Finally, I consider the theoretical consequences, particularly as concerns ontological parsimony, of treating difference as basic in these ways. My ultimate position is that there is a sense in which the second question from above is wrongheaded: difference and identity are, so to speak, features of the same ‘ideological apparatus’ (namely, that of quantification), so there is no real decision to be made about which to treat as basic. If this is correct, then the consequences for a theory's ontological parsimony that result from treating difference, identity, or both as basic are just the same as those that issue from the employment of quantification within a theory – namely, one's theory thereby incurs an ontological commitment to things.

Immanuel Kant states that indirect arguments are not suitable for the purposes of transcendental philosophy. If he is correct, this affects contemporary versions of transcendental arguments which are often used as an indirect refutation of scepticism. I discuss two reasons for Kant’s rejection of indirect arguments. Firstly, Kant argues that we are prone to misapply the law of excluded middle in philosophical contexts. Secondly, Kant points out that indirect arguments lack some explanatory power. They can show that something is true (...) but they do not provide insight into why something is true. Using mathematical proofs as examples, I show that this is because indirect arguments are non-constructive. From a Kantian point of view, transcendental arguments need to be constructive in some way. In the last part of the paper, I briefly examine a comment made by P. F. Strawson. In my view, this comment also points toward a connection between transcendental and constructive reasoning.

Philosophical Investigations, EarlyView.

This paper begins with a discussion of the logical apparatus of Frege, where his use of Sinn suggests a modification of Leibniz's Principle of the Identity of Indiscernibles. Then, it turns to Strawson's basic particulars with its essentially Kantian orientation. This brings forward the logical ground upon which the Identity Thesis rests. Finally, following Frege with some modifications, the paper suggests that an ontological list where concepts can be treated as objective (materially dependent) subsistent entities would be necessary in order (...) to avoid errors of J. J. C. Smart and other analytic philosophers who hold the Identity Thesis. (shrink)

Resumen: Derek Parfit en Personas, racionalidad y tiempo sostiene que si bien es posible concebir experiencias sin referir a personas, las experiencias dependen para su existencia de las personas, y a su vez, las experiencias dependerían para su identidad de cierta otra entidad no idéntica con la entidad persona. Tal tesis, que deviene de determinado experimentos mentales de Parfit, específicamente del argumento Mi División y el Argumento del Hospital, se revisará desde ciertas nociones metafísicas de E. J. Lowe, en específico, (...) desde la tesis que supone que dependencia de identidad implica dependencia existencial, de forma que si x depende para su identidad de y, x dependería, de igual forma, para su existencia de y. Tal supuesto permitirá desarrollar ciertas problemáticas para lo que Parfit sostiene en su esquema sobre la dependencia de las experiencias.: Derek Parfit in People, rationality and time argues that although it is possible to conceive experiences without referring to people, experiences depend on people for their existence, and in turn, experiences would depend on certain other entity not identical to the person entity for their identity. This thesis, which comes from certain mental experiments of Parfit, specifically from My Division argument and the Hospital Argument, will be reviewed from certain metaphysical notions of E. J. Lowe, specifically, from the thesis that assumes that identity dependence implies existential dependence, so that if x depends on the identity of y, x would depend, in the same way, on the existence of y. This assumption will bring to developing certain problems concerning what Parfit holds in his scheme on the dependence of experiences. (shrink)

In “Practical Knowledge of Language”, C.-h. Tsai criticizes the arguments in “Swimming and Speaking Spanish” (this issue, pp. 331–341), on the grounds that its account of knowledge of language as knowledge-how is mistaken. In its place, he proposes an alternative account in terms of Russell’s concept “knowledge-by-acquaintance”. In this paper, I show that this account succeeds neither in displacing the account in Swimming and Speaking Spanish nor in addressing Tsai’s main concern: solving the “delivery problem”.
