Developers are often the engine behind the creation and implementation of new technologies, including in the artificial intelligence surge that is currently underway. In many cases these new technologies introduce significant risk to affected stakeholders; risks that can be reduced and mitigated by such a dominant party. This is fully recognized by texts that analyze risks in the current AI transformation, which suggest voluntary adoption of ethical standards and imposing ethical standards via regulation and oversight as tools to compel developers (...) to reduce such risks. However, what these texts usually sidestep is the question of how aware developers are to the risks they are creating with these new AI technologies, and what their attitudes are towards such risks. This paper asks to rectify this gap in research, by analyzing an ongoing case study. Focusing on six Israeli AI startups in the field of radiology, I carry out a content analysis of their online material in order to examine these companies’ stances towards the potential threat their automated tools pose to patient safety and to the work-standing of healthcare professionals. Results show that these developers are aware of the risks their AI products pose, but tend to deny their own role in the technological transformation and dismiss or downplay the risks to stakeholders. I conclude by tying these findings back to current risk-reduction recommendations with regards to advanced AI technologies, and suggest which of them hold more promise in light of developers’ attitudes.

Following the lead of Duncan Pritchard’s “Wittgensteinian Pyrrhonism,” this paper takes a further, comparative and contrastive look at the problem of justification in Sextus Empiricus and in Wittgenstein’sOn Certainty. I argue both that Pritchard’s stimulating account is problematic in certain important respects and that his insights contain much interpretive potential still to be pursued. Diverging from Pritchard, I argue that it is a significant and self-conscious aspect of Sextus’ sceptical strategies to call into question large segments of our belief systemen (...) masseby exposing as apparently unjustifiable fundamental propositions which are closely related in their linchpin role to Wittgenstein’s hinge propositions. In the first instance, the result is a more complex account of both a deeper affinity between Wittgenstein’s approach to hinge propositions and Sextus’ approach to what I termarchaipropositions and a divergence between the two. In the second instance, I suggest how the comparison withOn Certaintycan be illuminating for the interpreter of Sextus. In particular, it can help us to see how the Pyrrhonist’s everyday conduct—common assumptions to the contrary notwithstanding—involves rational procedures of justification, in line with a naturalism reminiscent of Wittgenstein. Furthermore, it can help us to reflect on the Pyrrhonist’s attitude to what Wittgenstein would have called her ‘worldview’. Throughout, I suggest that the comparison with Wittgenstein is interesting, although it must be cashed out differently, not only on the interpretation—or, perhaps, strand—of ancient Pyrrhonism which has the sceptic exempt ordinary beliefs from her suspension of judgement, but also on the interpretation (or strand) which has her disavow all beliefs categorically.

This book provides the reader with a theoretical and practical understanding of two health care delivery models: the patient/child centred care and family-centred care. Both are fundamental to caring for children in healthcare organizations. The authors address their application in a variety of paediatric healthcare contexts, as well as the ethical and legal issues they raise. Each model is increasingly pursued as a vehicle for guiding the delivery of health care in the best interests of children. Such models of health (...) care delivery shape health care policies, programs, facility design, resource allocation decisions and day-to-day interactions among patients, families, physicians and other health care professionals. To maximize the health and ethical benefits these models offer, there must be shared understanding of what the models entail, as well as the ethical and legal synergies and tensions they can create. This book is a valuable resource for paediatricians, nurses, trainees, graduate students, practitioners of ethics and health policy. (shrink)

This book demonstrates that we need not choose between seeing so-called Presocratic thinkers as rational philosophers or as religious sages. In particular, it rethinks fundamentally the emergence of systematic epistemology and reflection on speculative inquiry in Hesiod, Xenophanes and Parmenides. Shaul Tor argues that different forms of reasoning, and different models of divine disclosure, play equally integral, harmonious and mutually illuminating roles in early Greek epistemology. Throughout, the book relates these thinkers to their religious, literary and historical surroundings. It (...) is thus also, and inseparably, a study of poetic inspiration, divination, mystery initiation, metempsychosis and other early Greek attitudes to the relations and interactions between mortal and divine. The engagements of early philosophers with such religious attitudes present us with complex combinations of criticisms and creative appropriations. Indeed, the early milestones of philosophical epistemology studied here themselves reflect an essentially theological enterprise and, as such, one aspect of Greek religion. (shrink)

This article argues that Empedocles’ trust in Strife (DK31 B115.14 = LM22 D10.14) is not, as the prevailing interpretation has it, only a past misjudgement and failure. Rather, trust in Strife still, and to his own lament, infects Empedocles’ mind and informs his life. This detail then offers a fresh perspective on Empedocles’ self-conception and on how, through the daimōn’s cosmic peregrinations, Empedocles raises and pursues questions of agency and responsibility. Furthermore, it sheds light on Empedocles’ understanding of his own (...) ethical standing: common assumptions to the contrary notwithstanding, he does not see himself as an unqualifiedly successful embodiment of his own ideals.

_ Source: _Volume 60, Issue 1, pp 3 - 39 This paper pursues a new approach to the problem of the relation between Alētheia and Doxa. It investigates as interrelated matters Parmenides’ impetus for developing and including Doxa, his conception of the mortal epistemic agent in relation both to Doxa’s investigations and to those in Alētheia, and the relation between mortal and divine in his poem. Parmenides, it is argued, maintained that Doxastic cognition is an ineluctable and even appropriate aspect (...) of mortal life. The mortal agent, however, is nonetheless capable of sustaining the cognition of Alētheia by momentarily coming to think with—or as—his divine soul. (shrink)

There have been recent disagreements in the philosophy of neuroscience regarding which sorts of scientific models provide mechanistic explanations, and which do not. These disagreements often hinge on two commonly adopted, but conflicting, ways of understanding mechanistic explanations: what I call the “representation-as” account, and the “representation-of” account. In this paper, I argue that neither account does justice to neuroscientific practice. In their place, I offer a new alternative that can defuse some of these disagreements. I argue that individual models (...) do not provide mechanistic explanations by themselves. Instead, individual models are always used to complement a huge body of background information and pre-existing models about the target system. With this in mind, I argue that mechanistic explanations are distributed across sets of different, and sometimes contradictory, scientific models. Each of these models contributes limited, but essential, information to the same mechanistic explanation, but none can be considered a mechanistic explanation in isolation of the others. (shrink)

A Prayer for the Government: Ukrainians and Jews in Revolutionary Times, 1917-1920. By Henry Abramson, xxi+255 pp. $36.95/£24.50/€36.95 cloth; $19.95/£13.50/€19.95 paper.

Traditionally, a scientific model is thought to provide a good scientific explanation to the extent that it satisfies certain scientific goals that are thought to be constitutive of explanation. Problems arise when we realize that individual scientific models cannot simultaneously satisfy all the scientific goals typically associated with explanation. A given model’s ability to satisfy some goals must always come at the expense of satisfying others. This has resulted in philosophical disputes regarding which of these goals are in fact necessary (...) for explanation, and as such which types of models can and cannot provide explanations. Explanatory monists argue that one goal will be explanatory in all contexts, while explanatory pluralists argue that the goal will vary based on pragmatic considerations. In this paper, I argue that such debates are misguided, and that both monists and pluralists are incorrect. Instead of any goal being given explanatory priority over others in a given context, the different goals are all deeply dependent on one another for their explanatory power. Any model that sacrifices some explanatory goals to attain others will always necessarily undermine its own explanatory power in the process. And so when forced to choose between individual scientific models, there can be no explanatory victors. Given that no model can satisfy all the goals typically associated with explanation, no one model in isolation can provide a good scientific explanation. Instead we must appeal to collections of models. Collections of models provide an explanation when they satisfy the web of interconnected goals that justify the explanatory power of one another.

A common view in the philosophy of mind and philosophy of psychology is that there is an ideally correct way of categorizing the structures and operations of the mind, and that the goal of neuroscience and psychology is to find this correct categorizational scheme. Categories which cannot find a place within this correct framework ought to be eliminated from scientific practice. In this paper, I argue that this general idea runs counter to productive scientific practices. Such a view ignores the (...) plurality of aims and goals that neuroscientists and psychologists have in studying mental phenomena, and the necessity of employing distinct classificatory frameworks to achieve them.

There is a long-standing debate in the philosophy of mind and philosophy of science regarding how best to interpret the relationship between neuroscience and psychology. It has traditionally been argued that either the two domains will evolve and change over time until they converge on a single unified account of human behaviour, or else that they will continue to work in isolation given that they identify properties and states that exist autonomously from one another (due to the multiple-realizability of psychological (...) states). In this paper, I argue that progress in psychology and neuroscience is contingent on the fact that both of these positions are false. Contra the convergence position, I argue that the theories of psychology and the theories of neuroscience are scientifically valuable as representational tools precisely because they cannot be integrated into a single account. However, contra the autonomy position, I propose that the theories of psychology and neuroscience are deeply dependent on one another for further refinement and improvement. In this respect, there is an irreconcilable codependence between psychology and neuroscience that is necessary for both domains to improve and progress. The two domains are forever linked while simultaneously being unable to integrate. (shrink)

This article explores the ethical challenges of providing Medical Assistance in Dying (MAID) in a paediatric setting. More specifically, we focus on the theoretical questions that came to light when we were asked to develop a policy for responding to MAID requests at our tertiary paediatric institution. We illuminate a central point of conceptual confusion about the nature of MAID that emerges at the level of practice, and explore the various entailments for clinicians and patients that would flow from different (...) understandings. Finally, we consider the ethical challenges of building policy on what is still an extremely controversial social practice. While MAID is currently available to capable patients in Canada who are 18 years or older—a small but important subsection of the population our hospital serves—we write our policy with an eye to the near future when capable young people may gain access to MAID. We propose that an opportunity exists for MAID-providing institutions to reduce social stigma surrounding this practice, but not without potentially serious consequences for practitioners and institutions themselves. Thus, this paper is intended as a road map through the still-emerging legal and ethical landscape of paediatric MAID. We offer a view of the roads taken and considered along the way, and our justifications for travelling the paths we chose. By providing a record of our in-progress thinking, we hope to stimulate wider discussion about the issues and questions encountered in this work. (shrink)

In this article, I argue that the use of scientific models that attribute intentional content to complex systems bears a striking similarity to the way in which statistical descriptions are used. To demonstrate this, I compare and contrast an intentional model with a statistical model, and argue that key similarities between the two give us compelling reasons to consider both as a type of phenomenological model. I then demonstrate how intentional descriptions play an important role in scientific methodology as a (...) type of phenomenal model, and argue that this makes them as essential as any other model of this type.

Sextus’ interpretation of Xenophanes’ scepticism in M 7.49–52 is often cited but has never been subject to detailed analysis. Such analysis reveals that Sextus’ interpretation raises far more complex problems than has been recognised. Scholars invariably assume one of two ways of construing his account of Xenophanes B34, without observing that the choice between these two alternatives poses an interpretive dilemma. Some scholars take it that Sextus ascribes to Xenophanes the view that one may have knowledge without knowing that one (...) has knowledge. Others take it that he ascribes to Xenophanes the view that one may have true belief without knowing that one has true belief. A close examination of Sextus’ paraphrase exposes a crucial but overlooked complication. Sextus elides Xenophanes’ pivotal distinction between knowing “the clear and certain” and believing “what has been fulfilled” . He eliminates altogether tetelesmenon from his analysis of B34, and expands the role of to saphes. I demonstrate that, as a result, Xenophanes B34, as interpreted by Sextus, does not consistently and straightforwardly express either view or view . Sextus, I argue, in fact develops a fundamentally incoherent interpretation of Xenophanes B34. On Sextus’ interpretation, Xenophanes justifies the proposition “No human knows” by arguing that, even if a human does, in fact, know, he does not know that he knows. Finally, I argue that Sextus’ incoherent account reflects not unthinking negligence, but a sophisticated if ultimately doomed attempt to interpret the logical structure of Xenophanes B34 in line with later models of second-order scepticism.

The study of psychological mechanisms is an interdisciplinary endeavour, requiring insights from many different domains. In this article, I argue that philosophy plays an essential role in this interdisciplinary project, and that effective scientific study of psychological mechanisms requires that working scientists be responsible metaphysicians. This means adopting deliberate metaphysical positions when studying mechanisms that go beyond what is empirically justified regarding the nature of the phenomenon being studied, the conditions of its occurrence, and its boundaries. Such metaphysical commitments are (...) necessary in order to set up experimental protocols, determine which variables to manipulate under experimental conditions, and which conclusions to draw from different scientific models and theories. It is important for scientists to be aware of the metaphysical commitments they adopt, since they can easily be led astray if invoked carelessly. (shrink)

In this article, I argue that intentional psychology (i.e. the interpretation of human behaviour in terms of intentional states and propositional attitudes) plays an essential role in the sciences of the mind. However, this role is not one of identifying scientifically respectable states of the world. Rather, I argue that intentional psychology acts as a type of phenomenological model, as opposed to a mechanistic one. I demonstrate that, like other phenomenological models in science, intentional psychology is a methodological tool with (...) its own benefits and insights that complements our mechanistic understanding of systems. As a result, intentional psychology's distinctive scientific benefit is its ability to model systems in unique, non-mechanistic, ways. This allows us to generate predictions that we cannot otherwise generate using the mechanistic models of neuroscience and cognitive psychology necessary for various scientific tasks. (shrink)

ABSTRACTThe quartz clock, the first to replace the pendulum as the time standard and later a ubiquitous and highly influential technology, originated in research on means for determining frequency for the needs of telecommunication and the interests of its users. This article shows that a few groups in the US, Britain, Italy and the Netherlands developed technologies that enabled the construction of the new clock in 1927–28. To coordinate complex and large communication networks, the monopolistic American Telephone and Telegraph Company, (...) and national laboratories needed to determine and maintain a common ‘standard’ frequency measurement unit. Exploiting novel piezoelectric quartz methods and valve electronics techniques, researchers in these organizations constructed a new crystal-based frequency standard. To ensure its accuracy they compared it to an accepted absolute standard - an astronomical clock, constructing thereby the first quartz clock. Other groups, however, had different, though connected, technological aims, which originated from the diverse interests of the industrial, governmental and academic institutes to which they belonged, and for which they needed to measure, control and manipulate with frequencies of electric oscillations. The present article suggests a comparative examination of the research and development paths of these groups on their incentives, the technological and scientific resources they utilized, and the kind of research carried out in the various institutional settings.

It has commonly been argued that certain types of mental descriptions, specifically those characterized in terms of propositional attitudes, are part of a folk psychological understanding of the mind. Recently, however, it has also been argued that this is the case even when such descriptions are employed as part of scientific theories in domains like social psychology and comparative psychology. In this paper, I argue that there is no plausible way to understand the distinction between folk and scientific psychology that (...) can support such claims. Moreover, these sorts of claims can have adverse consequences for the neuroscientific study of the brain by downplaying the value of many psychological theories that provide information neuroscientists need in order to build and test neurological models.

In their summary and critique, Gamble, Gamble, and Pruski mischaracterise both the central arguments and the primary objectives of our original paper. Our paper does not provide an ethical justification for paediatric Medical Assistance in Dying by comparing it with other end of life care options. In fact, it does not offer arguments about the permissibility of MAID for capable young people at all. Instead, our paper focuses on the ethical questions that emerged as we worked to develop a policy (...) for responding to MAID requests at our tertiary paediatric institution. Following the Supreme Court of Canada’s recent decriminalisation of MAID, our hospital needed to answer immediate on-the-ground questions such as: ‘What are we going to do if an 18-year-old patient in our care requested MAID today, as is now their legal right? How should we protect their privacy? What is the best way to ensure patients are informed when making these decisions?’ On these important questions, Gamble, Gamble, and Pruskiare silent. (shrink)

This essay is a close examination of one of Nahman of Bratslav's early and largely unexamined texts, Sefer ha‐Middot. The question it addresses is whether one can call this a study of “ethics” or, in Jewish nomenclature, musar, a work that seeks to cultivate human behaviors and describe ethical formation. In addition, it asks whether Sefer ha‐Middot can be called a text of “virtue ethics” given its focus on virtues and their enactment. The essay argues that Nahman's peculiar metaphysical notion (...) that all mitzvot are inextricably intertwined prevents any analysis of behavioral causality severing his “ethics” from any Aristotelian or Kantian tradition and brings him closer to Alasdair MacIntyre's notion of ethics as tied to traditional norms. And even with MacIntyre, the comparison is quite limited. Discussing “faith,” the “zaddik,” and “money,” the essay explores Nahman's view of how these and other virtues are cultivated and achieved.

Postliberal theology has been a topic of considerable theological debate over the past few decades. In his 2011 book Another Reformation, Peter Ochs deploys a postliberal theological model for the purpose of developing a sophisticated understanding of the future of interreligious relations. Ochs argues that postliberal theology is a reparative theology focusing on alleviating human suffering. He argues that the Christian idea of supersessionism may be the most challenging for Christians to confront as they explore avenues for making interreligious dialogue (...) more effective. Ochs critiques the Mennonite theologian John Howard Yoder's understanding of Zionism as Jewish Constantianism for being an instance of an ostensibly postliberal theology losing its way. In this essay, I offer a critique of Ochs's reading of Yoder, claiming that Yoder's view actually mirrors an important intra-Jewish debate about the relationship between political power and piety, and retrieves an ingenious contribution of both early Judaism and early Christianity that is effaced in today's growing Constantinian approach to Christian imperialism and Jewish nationalism.

This contribution to the Common Knowledge symposium on xenophilia examines the life choices of two Jews who loved Christianity. Elijah Zvi Soloveitchik, born into an ultra-Orthodox, nineteenth-century rabbinic dynasty in Lithuania, spent much of his life writing a Hebrew commentary on the Gospels in order to document and argue for the symmetry or symbiosis that he perceived between Judaism and Christianity. Oswald Rufeisen, from a twentieth-century secular Zionist background in Poland, converted to Catholicism during World War II, became a monk, (...) and attempted to immigrate to Israel as a Jew in 1958. Rufeisen, while permitted to move to Israel to join a Carmelite monastery in Haifa, was denied the right to immediate citizenship of Israel which the Law of Return guarantees to all bona fide Jews. And this particular Soloveitchik has largely been forgotten, given the limits of Jewish interest in the New Testament and of Christian attention to rabbinic literature. This article explores the complex and vexing questions that the careers of these two men raise about the elusive distinctions between Judaism and Christianity, on the one hand, and, on the other, between the Jewish religion and Jewish national identity.

In this response to the essays in the symposium on my book Meir Kahane: The Public Life and Political Thought of an American Jewish Radical I tried to clarify and expand some of the thoughtful and astute themes in the remarks of my interlocutors, especially about how the book was not intended to be about one figure but rather an intervention into postwar American and Israeli Judaism through the lens of a maligned figure who is ignored by most American Jews (...) and demonized by most Israeli Jews. Meir Kahane remains present because he never went away. And he never went away because he offered solutions that, while unpopular and egregious, continue to resonate when Jews begin to feel unstable about their place in America or Israel. He is the dark underside of the modern Jewish project that will not go away. (shrink)

This paper explores the current obstacles that a cognitive theory of humor faces. More specifically, I argue that the nebulous and ill-defined nature of humor makes it difficult to tell what counts as clear instances of, and deficits in, the phenomenon.Without getting clear on this, we cannot identify the underlying cognitive mechanisms responsible for humor. Moreover, being too quick to draw generalizations regarding the ubiquity of humor, or its uniqueness to humans, without substantially clarifying the phenomenon and its occurrences is (...) not only unwise but can actually be a detriment to our study of humor. As such, these sorts of claims must be resisted. I conclude the paper by pointing the way forward to addressing these obstacles. -/- . (shrink)

Some argue that the term “explanation” in science is ambiguous, referring to at least three distinct concepts: a communicative concept, a representational concept, and an ontic concept. Each is defined in a different way with its own sets of norms and goals, and each of which can apply in contexts where the others do not. In this paper, I argue that such a view is false. Instead, I propose that a scientific explanation is a complex entity that can always be (...) analyzed along a communicative dimension, a representational dimension, and an ontic dimension. But all three are always present within scientific explanations. I highlight what such an account looks like, and the potential problems it faces (namely that a single explanation can appear to have incompatible sets of norms and goals that govern it). I propose a solution to this problem and demonstrate how this account can help to dissolve current disputes in philosophy of science regarding debates between epistemic and ontic accounts of mechanistic explanations in the life sciences.

It is traditionally thought that integration in cognitive science requires combining different perspectives, elements, and insights into an integrated model or theory of the target phenomenon. In this paper I argue that this type of integration is frequently not possible in cognitive science due to our reliance on using different idealizing and simplifying assumptions in our models and theories. Despite this, I argue that we can still have integration in cognitive science and attain all the benefits that integrated models would (...) provide, without the need for their construction. Models which make incompatible idealizing assumptions about the target phenomenon can still be integrated by understanding how to draw coherent and compatible inferences across them. I discuss how this is possible, and demonstrate how this supports a different kind of integration. This sense of integration allows us to use collections of contradictory models to develop a consistent, comprehensive and non-contradictory understanding of a single unified phenomenon without the need for a single integrated model or theory.

This article tracks Derrida's readings of Kant and Husserl as they explore the relation between, on the one hand, faith and knowledge, and on the other, theory and practice. Kant had to limit the scope of theoretical knowledge in order to make room for a practical faith in the rational ideas of the unconditioned, generated through the unconditionality of the moral law. Husserl deployed the figure of ‘the Idea in the Kantian sense’ at those crucial moments in the exposition of (...) his transcendental phenomenology where the unconditioned comes into play, a problematic strategy that Derrida judges to have revealed the limits of the phenomenological project. While Husserl's call for an unconditional theoretical and practical renewal of faith in reason appears to offer him an out, Husserlian faith is ultimately dependent on an untenable circularity, to which the Kantian variety also succumbs. Only Derrida's unconditional gift of faith can save the honour of reason from its mortal crisis, but in a manner that is itself not wholly a matter of reason. (shrink)

Summary Between 1911 and 1914, Owen Richardson formulated a theory of photoelectricity based on thermodynamics and statistical reasoning. Although this theory succeeded in accounting for most of the relevant phenomena and despite the lack of competing causal or descriptive accounts of the phenomena, it failed to attract other physicists. This paper seeks the reasons for the neglect of this theory in contemporary cultures of photoelectric research. Four main causes of neglect are identified: the relatively high number and the nature of (...) the theory's assumptions, the contradiction of one of these assumptions with contemporary views, the failure to suggest new predictions or to account for hitherto unexplained regularities, and the view shared by many scientists that the problem of electromagnetic radiation required a radical solution that a descriptive theory could not provide. The expectation for a radical solution defines the revolutionary character of a research field. In the case of photoelectricity, it originated in a web of evidence to which other fields contributed. The very possibility of Richardson's theory shows that, taken separately, this phenomenon could receive an account which, unlike Einstein's light quantum, did not require deep changes in the conception of nature.

Officially inaugurated in 1925, the Hebrew University of Jerusalem was designed to serve the academic needs of the Jewish people and the Zionist enterprise in British Mandatory Palestine, as well as to help fulfill the economic and social requirements of the Middle East. It is intriguing that a university with such practical goals should have as one of its central pillars an institute for pure mathematics that purposely dismissed any of the varied fields of applied mathematics. This paper tells of (...) the preparations for the inauguration of the Hebrew University during the years 1920–1925 and analyzes the founding phase of the Einstein Institute of Mathematics that was established there during the years 1924–1928. Special emphasis is given to the first terms in which this Institute operated, starting from the winter of 1927 with the activities of the director and one of the founders, the German mathematician Edmund Landau, and onward from 1928 when his successors, particularly Adolf Abraham Halevi Fraenkel and Mihály-Michael Fekete, continued Landau's heritage of pure mathematics. The paper shows why and how the Institute succeeded in rejecting applied mathematics from its court and also explores the controversial issue of center and periphery in the development of science, a topic that is briefly analyzed in the concluding section.

Talk of “levels” can be found throughout the sciences, from “levels of abstraction”, to “levels of organization”, to “levels of analysis”. This has led to substantial disagreement regarding the ontology of levels, and whether the various senses of levels each have genuine value and utility to scientific practice. In this paper, I propose a unified framework for thinking about levels in science which ties together the various ways in which levels are invoked in science, and which can overcome the problems (...) that different senses of levels have faced. I argue that levels can best be understood as choices scientists make regarding what sort of information to foreground in their models and theories, and what sort of information to push into the background. To change levels is to change the foregrounding and backgrounding of information for different representational and pragmatic purposes. (shrink)

In his recent authoritative Helmholtz and the Conservation of Energy, Kenneth Caneva has claimed that earlier authors had invoked the principle of conservation of living force only in cases of a system returning to an earlier state, or of one without Newtonian forces. Relaying on texts in the tradition of the French Analytical Mechanics form Lagrange to Coriolis, I argue that this was not the case, and that the principle had been formulated and used for cases where living force proper (...) (mv2) was not conserved but its sum with an integral function (refers today as potential) was constant. In addition. I show that contrary to Caneva’s claim, the principle had been connected to the impossibility of creating power out of nothing. The two points indicate a stronger link between the analytical tradition and Helmholtz and his readers than usually portrayed, and the significant contribution of mechanics to the emergence of energy conservation. On a methodological level the use of living force shows that a common term and even a concept, like energy, is not always needed for its successful employment. (shrink)

In this dissertation, I examine the role that intentional descriptions play in our scientific study of the mind. Behavioural scientists often use intentional language in their characterization of cognitive systems, making reference to “beliefs”, “representations”, or “states of information”. What is the scientific value gained from employing such intentional terminology? I begin the dissertation by contrasting intentional descriptions with mechanistic descriptions, as these are the descriptions most commonly used to provide explanations in the behavioural sciences. I then examine the way (...) that intentional descriptions are employed in various scientific contexts. I conclude that while mechanistic descriptions characterize the underlying structure of systems, intentional descriptions allow us to generate predictions of systems while remaining agnostic as to their mechanistic underpinnings. Having established this, I then argue that intentional descriptions share much in common with statistical models in the way they characterize systems. Given these similarities, I theorize that intentional descriptions are employed within scientific practice as a particular type of phenomenological model. Phenomenological models are used to study, characterize, and predict the phenomena produced by mechanistic systems without describing their underlying structure. I demonstrate why such models are integral to our scientific discovery, and understanding, of the mechanisms that make up the brain. With my account on the table, I then look back at previous accounts of intentional language that philosophers have offered in the past. I highlight insights that each brought to our understanding of intentional language, and point out where each ultimately goes astray. I conclude the dissertation by examining the ontological implications of my theory. I demonstrate that my account is compatible with versions of both realism, and anti-realism, regarding the existence of intentional states. (shrink)
