I have two objectives in this article. The first is methodological: I elaborate a minimal phenomenological method and attempt to show its importance in studies of infant behavior. The second objective is substantive: Applying the minimal phenomenological approach, combined with Meltzoff’s “like-me” developmental framework, I propose the hypothesis that infants learn the pointing gesture at least in part through imitation. I explain how developments in sensorimotor ability (posture, arm and hand control and coordination, and locomotion) in the first year of (...) life prepare the infant for acquiring the pointing gesture. The former may directly enable the latter by allowing the infant to experience its own body as being “like those” of others, thus allowing it to imitatively appropriate a broader range of adult behavior. My proposal emphasizes the embodiment of mind in the development of cognition, contrary to latent dualistic tendencies in some developmental literature. (shrink)

Radical and autopoietic enactivists disagree concerning how to understand the concept of sense-making in enactivist discourse and the extent of its distribution within the organic domain. I situate this debate within a broader conflict of commitments to naturalism on the part of radical enactivists, and to phenomenology on the part of autopoietic enactivists. I argue that autopoietic enactivists are in part responsible for the obscurity of the notion of sense-making by attributing it univocally to sentient and non-sentient beings and following (...) Hans Jonas in maintaining a phenomenological dimension to life-mind continuity among all living beings, sentient or non-sentient. I propose following Merleau-Ponty instead, who offers a properly phenomenological notion of sense-making for which sentience is a necessary condition. Against radicalist efforts to replace sense-making with a deflationary, naturalist conception of intentionality, I discuss the role of the phenomenological notion of sense-making for understanding animal behavior and experience.

This paper clarifies Merleau-Ponty’s distinction between speaking and spoken speech, and the relation between the two, in his Phenomenology of Perception. Against a common interpretation, I argue on exegetical and philosophical grounds that the distinction should not be understood as one between two kinds of speech, but rather between two internally related dimensions present in all speech. This suggests an interdependence between speaking and spoken aspects of speech, and some commentators have critiqued Merleau-Ponty for claiming a priority of speaking over (...) spoken speech. However, there is a sense in which Merleau-Ponty is right to emphasize the priority, namely, in terms of the ontological priority of the speaking subject with respect to language understood as a constituted cultural ideality. The latter only maintains its ontological status insofar as it is taken up by a language community. I favorably contrast Merleau-Ponty’s views on this question to those of the late Heidegger and de Saussure, and suggest potential applications of this clarified position for contemporary discussions in philosophy of language.

Approaches to the naturalization of phenomenology usually understand naturalization as a matter of rendering continuous the methods, epistemologies, and ontologies of phenomenological and natural scientific inquiry. Presupposed in this statement of the problematic, however, is that there is an original discontinuity, a rupture between phenomenology and the natural sciences that must be remedied. I propose that this way of thinking about the issue is rooted in a simplistic understanding of the phenomenological reduction that entails certain assumptions about the subject matter (...) of phenomenology and its relationship to the natural sciences. By contrast, Merleau‐Ponty's first work, The Structure of Behavior, presents a radically different approach to the phenomenological reduction, one that traverses the natural sciences and integrates them into phenomenology from the outset. I outline the argument for this position in The Structure of Behavior and then discuss consequences for current methodological issues surrounding the naturalization of phenomenology, focusing on the relationship between empirical sciences of mind, phenomenological psychology, and transcendental phenomenology. This novel exegesis of Merleau‐Ponty's view on the reduction offers new insight into his oft‐quoted remark that the phenomenological reduction is impossible to complete. (shrink)

In this paper I develop a novel account of the phenomenality of language by focusing on characteristics of perceived speech. I explore the extent to which the spoken word can be said to have a horizonal structure similar to that of spatiotemporal objects: our perception of each is informed by habitual associations and expectations formed through past experiences of the object or word and other associated objects and experiences. Specifically, the horizonal structure of speech in use can fruitfully be compared (...) to that of a tool in use. The comparison suggests an account of our linguistic faculty as continuous with more foundational faculties of perception and action. I provide empirical corroboration of this account by drawing on recent neuroimaging studies of the multimodal, sensorimotor bases of speech comprehension. I then discuss how such an understanding of our linguistic ability helps advocates of embodied, non-representationalist accounts of cognition respond to a common objection. Critics grant that embodied approaches may be adequate to account for lower-level, online modes of cognition, such as perception and action, which directly engage their object. But they question whether such approaches can “scale up” to higher modes of cognition, such as imagination, memory, thought, and language, which can entertain absent, non-existent, or abstract objects. By providing a plausible account of the continuity of lower cognition and language-involving cognition, my approach responds to this objection, at least where language is concerned. (shrink)

This paper tracks the development of Merleau-Ponty's inquiries into language through the themes of institution, symbolism, and nature in his Collège de France lectures of 1953-1960. It seeks to show the continuity of Merleau-Ponty's inquiries over this period. The Problem of Speech course (1953-1954) constitutes his last extended treatment of speech, language, and expression, and it leaves many questions unanswered. Nonetheless, a careful study of the course reveals that the inquiries that follow into institution and symbolism, and later into nature, (...) do not mark a sharp rupture with his earlier thought. Rather, the later investigations are required by those into language and expression to clarify the underlying functions that support them. Ultimately, the themes of language and nature will be deeply interwoven in Merleau-Ponty's late thought, with institution and symbolism serving as important mediating concepts. (shrink)

Can it be rational to be risk-averse? It seems plausible that the answer is yes—that normative decision theory should accommodate risk aversion. But there is a seemingly compelling class of arguments against our most promising methods of doing so. These long-run arguments point out that, in practice, each decision an agent makes is just one in a very long sequence of such decisions. Given this form of dynamic choice situation, and the (Strong) Law of Large Numbers, they conclude that those (...) theories which accommodate risk aversion end up delivering the same verdicts as risk-neutral theories in nearly all practical cases. If so, why not just accept a simpler, risk-neutral theory? The resulting practical verdicts seem to be much the same. In this paper, I show that these arguments do not in fact condemn those risk-aversion-accommodating theories. Risk aversion can indeed survive the long run. (shrink)

Which is better: a guarantee of a modest amount of moral value, or a tiny probability of arbitrarily large value? To prefer the latter seems fanatical. But, as I argue, avoiding such fanaticism brings severe problems. To do so, we must decline intuitively attractive trade-offs; rank structurally identical pairs of lotteries inconsistently, or else admit absurd sensitivity to tiny probability differences; have rankings depend on remote, unaffected events ; and often neglect to rank lotteries as we already know we would (...) if we learned more. Compared to these implications, fanaticism is highly plausible. (shrink)

For aggregative theories of moral value, it is a challenge to rank worlds that each contain infinitely many valuable events. And, although there are several existing proposals for doing so, few provide a cardinal measure of each world's value. This raises the even greater challenge of ranking lotteries over such worlds—without a cardinal value for each world, we cannot apply expected value theory. How then can we compare such lotteries? To date, we have just one method for doing so (proposed (...) separately by Arntzenius, Bostrom, and Meacham), which is to compare the prospects for value at each individual location, and to then represent and compare lotteries by their expected values at each of those locations. But, as I show here, this approach violates several key principles of decision theory and generates some implausible verdicts. I propose an alternative—one which delivers plausible rankings of lotteries, which is implied by a plausible collection of axioms, and which can be applied alongside almost any ranking of infinite worlds. (shrink)

Aggregative moral theories face a series of devastating problems when we apply them in a physically realistic setting. According to current physics, our universe is likely _infinitely large_, and will contain infinitely many morally valuable events. But standard aggregative theories are ill-equipped to compare outcomes containing infinite total value so, applied in a realistic setting, they cannot compare any outcomes a real-world agent must ever choose between. This problem has been discussed extensively, and non-standard aggregative theories proposed to overcome it. (...) This paper addresses a further problem of similar severity. Physics tells us that, in our universe, how remotely in time an event occurs is _relative_. But our most promising aggregative theories, designed to compare outcomes containing infinitely many valuable events, are sensitive to how remote in time those events are. As I show, the evaluations of those theories are then relative too. But this is absurd; evaluations of outcomes must be absolute. So we must reject such theories. Is this objection fatal for all aggregative theories, at least in a relativistic universe like ours? I demonstrate here that, by further modifying these theories to fit with the physics, we can overcome it. (shrink)

This work provides proof-search algorithms and automated counter-model extraction for a class of STIT logics. With this, we answer an open problem concerning syntactic decision procedures and cut-free calculi for STIT logics. A new class of cut-free complete labelled sequent calculi G3LdmL^m_n, for multi-agent STIT with at most n-many choices, is introduced. We refine the calculi G3LdmL^m_n through the use of propagation rules and demonstrate the admissibility of their structural rules, resulting in auxiliary calculi Ldm^m_nL. In the single-agent case, we (...) show that the refined calculi Ldm^m_nL derive theorems within a restricted class of (forestlike) sequents, allowing us to provide proof-search algorithms that decide single-agent STIT logics. We prove that the proof-search algorithms are correct and terminate. (shrink)

Two key questions of normative decision theory are: 1) whether the probabilities relevant to decision theory are evidential or causal; and 2) whether agents should be risk-neutral, and so maximise the expected value of the outcome, or instead risk-averse (or otherwise sensitive to risk). These questions are typically thought to be independent---that our answer to one bears little on our answer to the other. But there is a surprising argument that they are not. In this paper, I show that evidential (...) decision theory implies risk neutrality, at least in moral decision-making and at least on plausible empirical assumptions. Take any risk-aversion-accommodating decision theory, apply it using the probabilities prescribed by evidential decision theory, and every verdict of moral betterness you reach will match those of expected value theory.

We present cut-free labelled sequent calculi for a central formalism in logics of agency: STIT logics with temporal operators. These include sequent systems for Ldm , Tstit and Xstit. All calculi presented possess essential structural properties such as contraction- and cut-admissibility. The labelled calculi G3Ldm and G3Tstit are shown sound and complete relative to irreflexive temporal frames. Additionally, we extend current results by showing that also Xstit can be characterized through relational frames, omitting the use of BT+AC frames.

STIT logic is a prominent framework for the analysis of multi-agent choice-making. In the available deontic extensions of STIT, the principle of Ought-implies-Can (OiC) fulfills a central role. However, in the philosophical literature a variety of alternative OiC interpretations have been proposed and discussed. This paper provides a modular framework for deontic STIT that accounts for a multitude of OiC readings. In particular, we discuss, compare, and formalize ten such readings. We provide sound and complete sequent-style calculi for all of (...) the various STIT logics accommodating these OiC principles. We formally analyze the resulting logics and discuss how the different OiC principles are logically related. In particular, we propose an endorsement principle describing which OiC readings logically commit one to other OiC readings. (shrink)

In this work we answer a long standing request for temporal embeddings of deontic STIT logics by introducing the multi-agent STIT logic TDS . The logic is based upon atemporal utilitarian STIT logic. Yet, the logic presented here will be neutral: instead of committing ourselves to utilitarian theories, we prove the logic TDS sound and complete with respect to relational frames not employing any utilitarian function. We demonstrate how these neutral frames can be transformed into utilitarian temporal frames, while preserving (...) validity. Last, we discuss problems that arise from employing binary utility functions in a temporal setting. (shrink)

We formally introduce a novel, yet ubiquitous, category of norms: norms of instrumentality. Norms of this category describe which actions are obligatory, or prohibited, as instruments for certain purposes. We propose the Logic of Agency and Norms (LAN) that enables reasoning about actions, instrumentality, and normative principles in a multi-agent setting. Leveraging LAN , we formalize norms of instrumentality and compare them to two prevalent norm categories: norms to be and norms to do. Last, we pose principles relating the three (...) categories and evaluate their validity vis-à-vis notions of deliberative acting. On a technical note, the logic will be shown decidable via the finite model property. (shrink)

Many real-world agents recognise that they impose harms by choosing to emit carbon, e.g., by flying. Yet many do so anyway, and then attempt to make things right by offsetting those harms. Such offsetters typically believe that, by offsetting, they change the deontic status of their behaviour, making an otherwise impermissible action permissible. Do they succeed in practice? Some philosophers have argued that they do, since their offsets appear to reverse the adverse effects of their emissions. But we show that (...) they do not. In practice, standard carbon offsetting does not reverse the harms of the original action, nor does it even benefit the same group as was harmed. Standard moral theories hence deny that such offsetting succeeds. Indeed, we show that any moral theory that allows offsetting in this setting faces a dilemma between allowing any wrong to be offset, no matter how grievous, and recognising an implausibly sharp discontinuity between offsettable actions and non-offsettable actions. The most plausible response is to accept that carbon offsetting fails to right our climate wrongs. (shrink)

Automated reasoning about uncertain knowledge has many applications. One difficulty when developing such systems is the lack of a completely satisfactory integration of logic and probability. We address this problem directly. Expressive languages like higher-order logic are ideally suited for representing and reasoning about structured knowledge. Uncertain knowledge can be modeled by using graded probabilities rather than binary truth-values. The main technical problem studied in this paper is the following: Given a set of sentences, each having some probability of being (...) true, what probability should be ascribed to other (query) sentences? A natural wish-list, among others, is that the probability distribution (i) is consistent with the knowledge base, (ii) allows for a consistent inference procedure and in particular (iii) reduces to deductive logic in the limit of probabilities being 0 and 1, (iv) allows (Bayesian) inductive reasoning and (v) learning in the limit and in particular (vi) allows confirmation of universally quantified hypotheses/sentences. We translate this wish-list into technical requirements for a prior probability and show that probabilities satisfying all our criteria exist. We also give explicit constructions and several general characterizations of probabilities that satisfy some or all of the criteria and various (counter) examples. We also derive necessary and sufficient conditions for extending beliefs about finitely many sentences to suitable probabilities over all sentences, and in particular least dogmatic or least biased ones. We conclude with a brief outlook on how the developed theory might be used and approximated in autonomous reasoning agents. Our theory is a step towards a globally consistent and empirically satisfactory unification of probability and logic. (shrink)

For almost half a century, the person most responsible for fomenting brouhahas regarding degrees of plasticity in the writing of histories has been Hayden White. Yet, despite the voluminous responses provoked by White’s work, almost no effort has been made to treat White’s writings in a systematic yet sympathetic way as a philosophy of history. Herman Paul’s book begins to remedy that lack and does so in a carefully considered and extremely scholarly fashion. In his relatively brief six chapters (...) (plus an introduction), Paul packs a wealth of information. He convincingly demonstrates that a guiding theme of White’s work from earliest times has been that historians have no choice but to impose a structure on historical data and thus bear responsibility for structures so imposed. As such, a key philosophical question concerns on what bases White contends that a freedom of choice exists regarding forms given to recorded histories. This essay focuses on how Paul argues for a unified vision that answers this question, as well as how he offers an original and comprehensive conception of White’s writings. (shrink)

Temporal Changes in Ovarian Gonadotropin-Releasing Hormone mRNA Levels by Gonadotropins in the Rat Sung Ho Lee, Eun-Seob Song, Sun Kyeong Yu, Changmee Kim, Dae Kee Lee, Wan Sung Choi l and Kyungjin Kim* Department of Molecular Biofogy and SRC for Cell Differentiation, Seoul National University, Seoul 150-742, Korea; IDepartment of Anatomy, College of Medicine, Gyeongsanf; National University, Chinju 660-280, Korea (Recei·. cd on December 29, 1993) The present study examines whether gonadotropins are involved in the regulation of ovarian GnRH gene (...) expression and how ovarian GnRH gene expression temporalJy correlates with alterations in hypothalamic GnRH, pituitary LH~ gene expression in respons to gonadotropins. Hypothalamic and ovarian GnRH mRNA and pituitary LH~ mRNA levels were determined by respective RNA-blot hybridizations, and ovarian GnRH and estradiol contents and serum LH levels were measured by respective radioimmunoassays. Three animal models such as 1) PMSG-treated, 2) PMSG and heG-treated immature rats and 3) proestrous stage of adult rats were used. Immature rats (25-days old) were administered with PMSG (10 iu) at 10:00 hand 48 h later with heG (10 iu) to induce ovulation. In the PMSG-injected model, hypothalamic GnRH mRNA levels were markedly augmented about 9-fold at 50 h, and pituitary LH mRNA 3-fold at 52 h after PMSG administration. Serum LH levels were increased to the preovulatory surge levels at 56 h, and ovarian GnRH mRNA levels were augmented 4-fold at 60 h after PMSG injection. Administration of heG also induced a marked enhancement in ovarian GnRH mRNA levels in comparison to the values shown in both intact and PMSGtreated rats at 52 hand 54 h, respectively. In the proestrous stage of normal adult rats, pituitary LH~ mRNA levels were peaked at 16:00 h. The preovulatory LH surge was evident at 4 h before increment in ovarian GnRH mRNA levels as shown in PMSG-treated rats. The present study clearly showed the sequential increase in hypothalamic GnRH mRNA, pituitary LH~ mRNA and ovarian GnRH mRNA levels, indicating that ovarian GnRH may play a possible role in the control of follicular maturation and the ovulation process.

Using a ‘reformulation of Bell’s theorem’, Waegell and McQueen (2020) argue that any empirically adequate theory that is local and does not involve retro-causation or fine-tuning must be a many-worlds theory. They go on to analyze several prominent many-worlds interpretations and conclude that non-separable many-worlds theories whose ontology is given by the wavefunction involve superluminal causation, while separable many-worlds theories (e.g. Waegell, 2021; Deutsch and Hayden 2000) do not. I put forward three claims. (A) I challenge their argument for (...) relying on a non-trivial, unquestioned assumption about elements of reality which allows Healey’s approach (Healey, 2017b) to evade their claim. In an attempt to respond to (A), Waegell and McQueen may restrict their claim to theories which satisfy such an assumption, however, I also argue that (B) their argument fails to prove even the so weakened claim, as exemplified by theories that are both non-separable and local. Finally, (C) by arguing for the locality of the decoherence-based Everettian approach (Wallace, 2012) I refute Waegell and McQueen’s claim that wavefunction-based ontologies, and more generally non-separable ontologies, involve superluminal causation. I close with some doubtful remarks about separable Everettian interpretations as compared to non-separable ones. (shrink)

This paper explores the relation between victims’ stories and normativity. As a contribution to understanding how the stories of those who have been abused or oppressed can advance moral understanding, catalyze moral innovation, and guide social change, this paper focuses on narrative as a variegated form of representation and asks whether personal narratives of victimization play any distinctive role in human rights discourse. In view of the fact that a number of prominent students of narrative build normativity into their accounts, (...) it might seem obvious that there is a connection between victims’ stories and moral insight. However, the category of victims’ stories spans an enormous variety of texts – private diaries, memoirs written for publication, interviews with journalists or social scientists, depositions prepared by human rights workers, stories shared with like-minded activists or with support groups, stories told to medical professionals, and testimony in courts, truth commissions and asylum hearings, to mention just some of the possibilities. The different contexts of elicitation and the different rules governing expression in these sites should make us wary of ready generalizations about the nature of victims’ narratives. Moreover, I doubt that existing explications of the way in which norms figure in narratives yield satisfactory theories of the contribution victims’ stories can make to discovering and defending just policies and practices. I consider two of the most prominent accounts of the relation between narrative and normativity. For different reasons, the account Anthony Amsterdam and Jerome Bruner present in their work on narrative and law and the account Hayden White presents in his work on narrative and history fail to appreciate the capacity of victims’ stories of abuse to advance understanding of and increase respect for human rights. In defense of the value of victims’ stories, I propose an account of the relation between normativity and a salient type of victim’s narrative that seems especially resistant to integration into human rights discourse. -/- .
