This open access monograph offers a detailed study and a systematic defense of a key intuition we typically have, as human beings, with respect to the nature of time: the intuition that the future is open, whereas the past is fixed. For example, whereas it seems unsettled whether there will be a fourth world war, it is settled that there was a first world war. -/- The book contributes, in particular, three major and original insights. First, it provides a coherent, (...) non-metaphorical, and metaphysically illuminating elucidation of the intuition. Second, it determines which model of the temporal structure of the world is most appropriate to accommodate the intuition, and settles on a specific version of the Growing Block Theory of time (GBT). Third, it puts forward a naturalistic foundation for GBT, by exploiting recent results of our best physics (viz. General Relativity, Quantum Mechanics, and Quantum Gravity). Three main challenges are addressed: the dismissal of temporal asymmetries as non-fundamental phenomena only (e.g., thermodynamic or causal phenomena), the epistemic objection against GBT, and the apparent tension between GBT and relativistic physics. It is argued that the asymmetry between the open future and the fixed past must be grounded in the temporal structure of the world, and that this is neither precluded by our epistemic device, nor by the latest approaches to Quantum Gravity (​e.g., the Causal Set Theory). -/- Aiming at reconciling time as we find it in ordinary experience and time as physics describes it, this ​innovative book ​will raise the interest of both academic researchers and ​graduate students working on the philosophy of time. More generally, it ​presents contents of interest for all metaphysicians and non-dogmatic philosophers of physics. (shrink)

Two enzymes involved in the synthesis of pyrimidine and purine nucleotides, CTP synthase (CTPS) and IMP dehydrogenase (IMPDH), can assemble into a single or very few large filaments called rods and rings (RR) or cytoophidia. Most recently, asymmetric cytoplasmic distribution of organelles during cell division has been described as a decisive event in hematopoietic stem cell fate. We propose that cytoophidia, which could be considered as membrane‐less organelles, may also be distributed asymmetrically during mammalian cell division as previously described for (...) Schizosaccharomyces pombe. Furthermore, because each type of nucleotide intervenes in distinct processes (e.g., membrane synthesis, glycosylation, and G protein‐signaling), alterations in the rate of synthesis of specific nucleotide types could influence cell differentiation in multiple ways. Therefore, we hypothesize that whether a daughter cell inherits or not CTPS or IMPDH filaments determines its fate and that this asymmetric inheritance, together with the dynamic nature of these structures enables plasticity in a cell population.

Desire-satisfaction theories of welfare must answer the timing question: when do you benefit from the satisfaction of one of your desires? There are three existing views about this: the Time of Desire view, on which you benefit at just those times when you have the desire; the Time of Object view, on which you benefit just when the object of your desire obtains; and Concurrentism, on which you benefit just when you have the desire and its object obtains. This paper (...) introduces a new view, Asymmetrism, on which you sometimes benefit at the time of desire and sometimes benefit at the time of object. On this view, if the time at which you have a desire is later than the time at which its object obtains, then you benefit at the time of the desire. On the other hand, if the time of object is later than the time of desire, then you benefit at the time of object. Three arguments are given for the conclusion that Asymmetrism is superior to the Time of Desire and Time of Object views. It is argued that Asymmetrism and Concurrentism are the most credible answers to the timing question. (shrink)

Three‐ to 4‐month‐old infants show asymmetric exclusivity in the acquisition of cat and dog perceptual categories. The cat perceptual category excludes dog exemplars, but the dog perceptual category does not exclude cat exemplars. We describe a connectionist autoencoder model of perceptual categorization that shows the same asymmetries as infants. The model predicts the presence of asymmetric retroactive interference when infants acquire cat and dog categories sequentially. A subsequent experiment conducted with 3‐ to 4‐month‐olds verifies the predicted pattern of looking time (...) behaviors. We argue that bottom‐up, associative learning systems with distributed representations are appropriate for modeling the operation of short‐term visual memory in early perceptual category learning.

Personal identity is not always symmetric: even if I will not be a later person, the later person may have been me. What makes this possible is that the relations that are criterial of personal identity---such as memory and anticipation---are asymmetric and "count in favor of personal identity from one side only". Asymmetric personal identity can be accommodated by temporal counterpart theory but not by Lewisian overlapping aggregates of person stages. The question of uncertainty in cases of personal fission (and (...) in Everettian quantum mechanics) is also discussed. (shrink)

In this paper, I argue on empirical grounds that (VL-initial) Asymmetric Coordination in German cannot be reduced to a syntactic structure of the form [if S1, then S2], but rather needs to be analyzed as some kind of adjunction to the if-clause, i.e., along the lines of [[if S1] and S2]. This conclusion gives rise to an apparent mismatch between syntactic structure (narrow scope of if) and semantic interpretation (wide scope of if). To resolve this paradoxical situation, I propose a (...) compositional semantics for conditionals that is based on the idea that (indexed) if is to be construed as some kind of anaphor (variable) that ranges over objects of type modal base picking up a modal background in the actual context. Even though this analysis assigns a non-vacuous semantics to the complementizer if, it is still compatible with the syntax of Asymmetric Coordination in German, and, in contrast to alternative accounts, avoids the generation of non-existent distributive readings.

It is commonly observed that we live in an increasingly polarised world. Strikingly, we are polarised not only about political issues, but also about scientific issues that have political implications, such as climate change. This raises two questions. First, why are we so polarised over these issues? Second, does this mean our views about these issues are all equally ir/rational? In this chapter I explore both questions. Specifically, I draw on the literature on ideologically motivated reasoning to develop an answer (...) to the first question. Put briefly, we exhibit “directional biases” in our information processing: we try to assimilate new information into our existing webs of beliefs. This means that those who are predisposed to accept the case for climate change end up accepting it, whereas those who are predisposed to reject it end up rejecting it. Based on this answer, I then address the second question. I look at some reasons for thinking that, because we all exhibit such biases in our thinking, we are all equally rational (or, as the case may be, irrational). I also suggest some ways you might try reject these reasons. (shrink)

The segregation of damaged components at cell division determines the survival and aging of cells. In cells that divide asymmetrically, such as Saccharomyces cerevisiae, aggregated proteins are retained by the mother cell. Yet, where and how aggregation occurs is not known. Recent work by Zhou and collaborators shows that the birth of protein aggregates, under specific stress conditions, requires active translation, and occurs mainly at the endoplasmic reticulum. Later, aggregates move to the mitochondrial surface through fis1‐dependent association. During replicative aging, (...) aggregate association with the mother‐cell mitochondria contributes to the asymmetric segregation of aggregates, because mitochondria in the daughter cell do not carry aggregates. With increasing age of mother cells, aggregates lose their connection to the mitochondria, and segregation is less asymmetric. Relating these findings to other mechanisms of aggregate segregation in different organisms, we postulate that fusion between aggregates and their tethering to organelles such as the vacuole, nucleus, ER, or mitochondria are common principles that establish asymmetric segregation during stress resistance and aging.

One persistent puzzle in the life sciences is the asymmetric lipid composition of the cellular plasma membrane: while the exoplasmic leaflet is enriched in lipids carrying predominantly saturated fatty acids, the cytoplasmic leaflet hosts preferentially lipids with (poly‐)unsaturated fatty acids. Given the high energy requirements necessary for cells to maintain this asymmetry, the question naturally arises regarding its inherent benefits. In this paper, we propose asymmetry to represent a potential solution for harmonizing two conflicting requirements for the plasma membrane: first, (...) the need to build a barrier for the uncontrolled influx or efflux of substances; and second, the need to form a fluid and dynamic two‐dimensional substrate for signaling processes. We hence view here the plasma membrane as a composite material, where the exoplasmic leaflet is mainly responsible for the functional integrity of the barrier and the cytoplasmic leaflet for fluidity. We reinforce the validity of the proposed mechanism by presenting quantitative data from the literature, along with multiple examples that bolster our model. (shrink)

Frequently, historical comparisons are asymmetrical in the sense that they investigate one case carefully while limiting themselves to a mere sketch of the other case which serve as comparative reference point. The debate on the German Sonderweg and the rich historical literature originating from this debate can serve as examples. This article reconstructs the pros and cons within this controversial debate, reports its results and puts it into a broader historical context. It analyzes the comparative logic implied by the Sonderweg (...) thesis and argues that the interpretation of modern German history in the sense of a Sonderweg can only be maintained if related to the question why Germany turned fascist and totalitarian in the interwar period while other societies did not, and if Western countries are selected as units of comparison. The choice of comparative reference points turns out to be decisive and partly dependent on normative priorities and conventions. The article points to dangers and opportunities inherent in asymmetrical comparison. (shrink)

The epistemic barriers to interdisciplinarity are understudied. To fill this gap, we ask whether a university initiative designed to reduce structural barriers to interdisciplinarity also facilitates the dissolution of epistemic ones. Through analytical autoethnography of graduate training in two disciplines, sociology and ecology, we develop the concept of asymmetric epistemology to better understand the unique epistemological position that emerges for interdisciplinarians. Building from feminist science and technology studies (STS) and scholarship on epistemic identities, our work illuminates how epistemologies are embodied (...) by individuals, leading to tensions around identity, materiality, and spatiality during the practice of interdisciplinarity. While some epistemic barriers recede and others remain, we reveal that the navigation of these boundaries deeply impacts individuals’ epistemic identities. (shrink)

In this essay, I defend an account of right action that I shall call “asymmetrical virtue particularism.” An action, on this account, is right just insofar as it is overall virtuous. But the virtuousness of an action in any particular respect, X, is deontically variant; it can fail to be right-making, either because it is deontically irrelevant or because it is wrong-making. Finally, the account is asymmetrical insofar as the viciousness of actions is not deontically variant; if any action is (...) vicious in some respect Y, then Y is always a wrong-making feature of any action whatever that has Y.

Ismael aims for an understanding of the nature of an embedded perspective of agents in a world. If successful, this would explain a cluster of ways in which from an embedded perspective, we experience the world in an array of temporally asymmetric ways. Moreover, these are ways that have led many philosophers to rather metaphysically inflationary views about the nature of time, according to which time itself really is dynamical, and is characterized by the movement of an objectively (i.e., non-perspectival) (...) present. Ismael aims to explain these features of our experience without positing any such metaphysical picture. She argues that there are constraints which prevent us from taking this Olympian conception of the world and our place in it, and that these, jointly, explain why we experience the world in these temporally asymmetric ways. We take up two related questions. First, what it would mean to say that these constraints are not merely epistemic, and second, how far these constraints get us in explaining why we experience the world in these ways. (shrink)

Three major ways in which temporal asymmetries enter into scientific induction are discussed as follows: 1. An account is given of the physical basis for the temporal asymmetry of recordability, which obtains in the following sense: except for humanly recorded predictions and one other class of advance indicators to be discussed, interacting systems can contain reliable indicators of only their past and not of their future interactions. To deal with the exceptional cases of non-spontaneous "pre-records," a clarification is offered of (...) the essential differences in the conditions requisite to the production of an indicator having retrodictive significance ("post-record"), on the one hand, and of one having predictive significance ("prerecord" or recorded prediction), on the other. Purported counter-examples to the asymmetry of spontaneous recordability are refuted. 2. It is shown how in cases of asymmetric recordability, the associated retrodiction-prediction asymmetry makes for an asymmetry of assertibility as between an explanandum (or an explanans) referring to a future event and one referring to a past one. But it is argued that this epistemological asymmetry in the assertibility per se must be clearly distinguished from a logical asymmetry between the past and the future in regard to the inferability (deductive or inductive) of the explanandum from the explanans. And it is then contended that the failure to distinguish between an epistemological and a logical asymmetry vitiates the critiques that recent writers have offered of the Popper-Hempel thesis, which affirms symmetry of inferability as between predictive and post-explanatory arguments. In reply to Scriven, it is maintained that predictions based on mere indicators (rather than causes) do not establish an asymmetry in scientific understanding as between predictive arguments and post-explanatory ones. 3. As a further philosophical ramification of the retrodiction-prediction asymmetry, a set of sufficient conditions are stated for the correctness of philosophical mechanism as opposed to teleology.

Hebrew and Arabic in Asymmetric Contact in Israel Israeli Hebrew and Palestinian Arabic 1 have existed side by side for well over a century in extremely close contact, accompanied by social and ideological tension, often conflict, between two communities: PA speakers, who turned from a majority to a minority following the establishment of the State of Israel in 1948, and IH speakers, the contemporary majority, representing the dominant culture. The Hebrew-speaking Jewish group is heterogeneous in terms of lands of origin (...) and includes a large community of Judeo-Arabic speakers. In this paper I discuss the ‘when,’ ‘where,’ how,' and especially ‘why’ of mutual borrowing2 between Hebrew and Arabic in Israel since the 1880s.I stress that the contact is asymmetric. The majority of Hebrew speakers today do not speak Arabic. They do, however, have access to borrowed lexicon in the domain of slang and vernacular speech that both enriches these registers and provides the speakers with a feeling of being ‘indigenous’ and ‘belonging’ to the social and cultural milieu of the larger environment. In contrast, most young adult PA-speakers are bilingual. For this minority, borrowing fulfills fundamental sociolinguistic and pragmatic needs. IH lexical items have permeated all areas of professional, educational, administrative, and social activities in everyday life discourse in all styles and registers of the spoken language and, to a lesser extent, written language. They fill lexical gaps and lacunae representing modern and western concepts that did not exist in PA. They also symbolize modernism, education, and social mobility. In other words, borrowing serves as a means of ‘stepping in’ for the Jewish majority and conversely as a means for ‘stepping out and up’ for the Arab minority. (shrink)

This article addresses the question whether companies benefit from their commitment to corporate social responsibility. The authors argue that firms which score high on CSR activities build investor confidence and find evidence that they benefit from lower information asymmetry. The authors measure information asymmetry by insider trading, which is defined as the trading of a company’s shares by corporate insiders who have an information advantage with the aim to reap gains or avoid losses. Using a sample of U.S. firms listed (...) in the MSCI World Index during the period 2004 to 2013 and the firm- and industry-level CSR rating from Global Engagement Service, the authors show that insider transactions in firms with a high score on CSR activities lead to lower abnormal returns. This investigation extends current literature on the business case for CSR by explaining the influence of CSR activities on asymmetric information. (shrink)

Asymmetric cell division generates cell diversity and contributes to cellular aging and rejuvenation. Here, we review the molecular mechanisms enabling budding yeast to recognize spindle pole bodies (SPB, centrosome equivalent) based on their age, and guide their non‐random mitotic segregation: SPB inheritance requires the distinction of old from new SPBs and is regulated by the SPB‐inheritance network (SPIN) and the mitotic exit network (MEN). The SPIN marks the pre‐existing SPB as old and the MEN recognizes these marks translating them into (...) spindle orientation. We next revisit other molecules and structures that partition depending on their age rather than their abundance at mitosis as, for example, DNA, centrosomes, mitochondria, and histones in yeast and other systems. The recurrence of this differential behavior suggests a functional significance for numerous cell types, which we then discuss. We conclude that non‐random segregation may facilitate asymmetric cell fate determination and thereby indirectly aging and rejuvenation. (shrink)

One vexing question for Desire Satisfactionism is this: At what time do you benefit from a satisfied desire? Recently Eden Lin has proposed an intriguing answer. On this proposal – Asymmetrism – when past-directed desires are satisfied, the time interval during which you benefit is the time of the desire; and, when future-directed desires are satisfied, the time interval during which you benefit is the time of the object. In this essay, I argue that Asymmetrism forces us to (...) give implausible answers to a different question: To what extent does a given satisfied desire benefit you? (shrink)

This thesis is guided by the following question: what, if anything, makes a life meaningful? My answer to this question is asymmetric welfarism about meaning in life. According to asymmetric welfarism, the meaning of a life depends upon two factors. First, a life is conferred meaning insofar as it promotes or protects the well-being of other welfare subjects. Second, a life is made meaningless insofar as it decreases or minimises the well-being of other welfare subjects. The meaning of a life (...) is determined by the net balance between these two factors; the more the good outweighs the bad, the more meaningful a life that is. I argue that asymmetric welfarism is the most plausible theory about meaning in life. To do this, I show how such a view captures a variety of intuitions about meaning in life while defending it from objections. This is the business of chapters 1, 2, and 3. Specifically, chapter 1 lays the groundwork, chapter 2 advances the case in favour of asymmetric welfarism, while chapter 3 defends asymmetric welfarism from objections. But some objections cannot be so easily overturned by a mere argument. Such objections do not just count against asymmetric welfarism, but also support competing theories. In order to overcome both, I show how such objections, and the theories they motivate, are best understood as tracking a different, but related, evaluative dimension a life can have. This is the business of chapters 4, 5, and 6. Specifically, chapter 4 argues that subjective theories are best understood as being about fulfilment, chapter 5 argues that purpose theories are best understood as being about purpose, and chapter 6 argues that differing views about the role of morality confuse morality and significance with meaning. These other evaluative dimensions which stand alongside meaning in life are fulfilment, purpose, significance, morality, and prudential value. (shrink)

According to Mitchell Green, speech act theory traditionally idealizes away from crucial aspects of conversational contexts, including those in which the speaker’s social position affects the possibility of her performing certain speech acts. In recent times, asymmetries in communicative situations have become a lively object of study for linguists, philosophers of language and moral philosophers: several scholars view hate speech itself in terms of speech acts, namely acts of subordination. The aim of this paper is to address one of the (...) main objections to accounts of hate speech in terms of illocutionary speech acts, that is the Authority Problem. While the social role of the speaker is the focus of several approaches, the social role of the audience has too often been neglected. The author will show that not only must the speaker have a certain kind of standing or social position in order to perform speech acts of subordination, but also the audience must typically have a certain kind of standing or social position in order to either license or object to the speaker’s authority, and her acts of subordination.

Our target article modeled conflict within and between groups as an asymmetric game of strategy and developed a framework to explain the evolved neurobiological, psychological, and sociocultural mechanisms underlying attack and defense. Twenty-seven commentaries add insights from diverse disciplines, such as animal biology, evolutionary game theory, human neuroscience, psychology, anthropology, and political science, that collectively extend and supplement this model in three ways. Here we draw attention to the superordinate structure of attack and defense, and its subordinate means to meet (...) the end of status quo maintenance versus change, and we discuss how variations in conflict structure and power disparities between antagonists can impact strategy selection and behavior during attack and defense; how the positions of attack and defense emerge endogenously and are subject to rhetoric and propaganda; and how psychological and economic interventions can transform attacker-defender conflicts into coordination games that allow mutual gains and dispute resolution.

Asymmetric Choquet random walks are defined, in the form of dynamically consistent random walks allowing for asymmetric conditional capacities. By revisiting Kast and Lapied and Kast et al. we show that some findings regarding the effects of ambiguity aversion are preserved in the more general framework, which is of interest in several applications to policy making, risk management, corporate decisions, real option valuation of investment/ disinvestment projects, etc. The effect of ambiguity on the higher moments is investigated, as well, as (...) they have an interpretation in terms of the psychological attitude of a decision-maker towards ambiguity. Finally, some financial applications are provided as an illustration. (shrink)

This paper examines the relationship between individuals' gender and their ethical decision models. The study seeks to identify asymmetries in men's and women's approaches to ethical decision making and differences in their perceptions of how same-sex and other-sex managers would likely act in business and nonbusiness situations that present an ethical dilemma. Results indicate that the models employed by men and women differ in both business and nonbusiness settings, that both sexes report changing models when leaving business settings, and that (...) women were better predictors of both sex's likely ethical models.

Current treatments of practical rationality understand reasons as considerations counting in favor of or against some practical option, treating the positive and the negative case as symmetrical. Typically the focus is on examples of positive reasons. However, I want to shift the spotlight to negative reasons, as making a tighter or more direct link to rationality — and ultimately to morality, which is what much of the current interest in reasons is meant to clarify. Recognizing a positive/negative asymmetry in normative (...) force will let us reconcile the view of moral or other requirements as based on reasons with the denial that reasons as such, even all-thingsconsidered reasons, yield requirements — or as I like to put it, rationally compel.

We apply the method of asymmetric interpretation to the basic fragment of bounded arithmetic, endowed with a weak collection schema, and to a system of “feasible analysis”, introduced by Ferreira and based on weak König's lemma, recursive comprehension and NP-notation induction. As a byproduct, we obtain two conservation results.

Asymmetry theories about free will and moral responsibility are a recent development in the long history of the free will debate. Kant commentators have not yet explored the possibility of an asymmetrical reconstruction of Kant's theory of freedom, and that is my goal here. By "free will", I mean the sort of control we would need to be morally responsible for our actions. Kant's term for it is "transcendental freedom", and he refers to the attribution of moral responsibility as "imputation". (...) By "Kant's theory of freedom", I mean not only his theory of transcendental freedom and imputation, but also the various ways in which he draws on these ideas in his moral theory. (shrink)

When people combine concepts these are often characterised as “hybrid”, “impossible”, or “humorous”. However, when simply considering them in terms of extensional logic, the novel concepts understood as a conjunctive concept will often lack meaning having an empty extension (consider “a tooth that is a chair”, “a pet flower”, etc.). Still, people use different strategies to produce new non-empty concepts: additive or integrative combination of features, alignment of features, instantiation, etc. All these strategies involve the ability to deal with conflicting (...) attributes and the creation of new (combinations of) properties. We here consider in particular the case where a Head concept has superior ‘asymmetric’ control over steering the resulting concept combination (or hybridisation) with a Modifier concept. Specifically, we propose a dialogical approach to concept combination and discuss an implementation based on axiom weakening, which models the cognitive and logical mechanics of this asymmetric form of hybridisation.

In this article, I argue that Hegel’s concept of recognition and Levinas’ concept of responsibility complement each other and lead to the idea of an asymmetrical reciprocity in which the origin of our social relations is not mutual equality, but rather mutual inequality. I will unfold this argument in three steps. I will first work out a fundamental asymmetry of recognition in Hegel by means of the figure of the bondsman before elucidating in a second step the asymmetry of responsibility (...) in Levinas by means of the figure of the hostage. In the last and third step, I will correlate both asymmetries and show how far the asymmetry of recognition and the asymmetry of responsibility constantly develop from and transition into one another in our social relationships.

A model of a Markov process is presented in which observing the present state of a system is asymmetrically related to inferring the system's future and inferring its past. A likelihood inference about the system's past state, based on observing its present state, is justified no matter what the parameter values in the model happen to be. In contrast, a probability inference of the system's future state, based on observing its present state, requires further information about the parameter values.

Analogies must be symmetric. If a is like b, then b is like a. So if a has property R, and if R is within the scope of the analogy, then b (probably) has R. However, analogical arguments generally single out, or depend upon, only one of a or b to serve as the basis for the inference. In this respect, analogical arguments are directed by an asymmetry. I defend the importance of this neglected – even when explicitly mentioned – (...) feature in understanding analogical arguments. (shrink)

A series of experiments involving two and three-player repeated guessing games with unique equilibrium is conducted. We find that equilibrium behavior is observed less frequently and overall choices are farther from the equilibrium in two-player asymmetric games in contrast to symmetric games, but this is not the case in three-player games. Convergence towards equilibrium exists in all cases but asymmetry slows down the speed of convergence to the equilibrium in two, but not in three-player games. Furthermore, the strong players have a slight earning advantage over the weak players, and asymmetry increases the discrepancy in choices (defined as the squared distance of choices from the winning number) in both games.

Aristotle distinguishes friendships of pleasure or utility from more valuable ‘character friendships’ in which the friend cares for the other qua person for the other’s own sake. Aristotle and some neo-Aristotelians require such friends to be fairly strictly symmetrical in their separateness of identity from each other, in the degree to which they identify with each other, and in the degree to which they are virtuous. We argue that there is a neglected form of valuable friendship–neither of friendship nor utility–that (...) allows significant asymmetries. We know of no sustained discussion of such ‘asymmetrical’ friendships in the literature. (shrink)

ABSTRACT In this article I freely use the thought of Charles Hartshorne to defend the ethical permissibility of abortion in the early stages of pregnancy. In the later stages of pregnancy the fetus has an ethical status similar to that of a sentient yet non‐rational animal, a status which should generate in us considerable ethical respect. The distinctiveness of this Hartshornian approach lies in the effort to bring metaphysics to bear on a controversial issue in applied ethics. In particular, the (...) metaphysical issue of temporal relations is crucial to consider in the effort to ascertain the ethical status of the fetus. Two symmetrical (immoderate) theories of temporal relations are criticised, one of which provides the basis for opposition to abortion, a theory wherein one is internally related both to one's past and to one's future. An asymmetrical (moderate) theory of temporal relations is defended, a theory wherein one is internally related to one's past yet externally related to the future. This latter theory would permit abortion in the early stages of pregnancy. (shrink)

Jerry Fodor has proposed a causal theory of meaning based on the notion of a certain asymmetric dependency between the causes of a symbol's tokens. This theory is held to be an improvement on Dennis Stampe's causal theory of meaning and Fred Dretske's information theoretic account, because it allegedly solves what Fodor calls the “disjunction problem”, and does so without recourse to the kind of optimal (ideal) conditions to which Stampe and Dretske appeal. A series of counterexamples is proposed to (...) Fodor's account, which, it is argued, can only be met by reintroducing that same appeal to optimal conditions that he had sought to eliminate. It is then argued that Fodor's notion of asymmetric dependence is not fundamental to the explanation of why a symbol means what it does: on the contrary, the symbol's meaning what it does is explanatorily prior to the obtaining of the asymmetry, so the asymmetry cannot be used to explain the symbol's meaning. Finally, it is argued that the “disjunction problem “ as it is defined by Fodor is not a genuine problem for causal theories of meaning. (shrink)

Progress in understanding the mind-body problem can be made without attempting to solve it as one unified problem, which it is not. Pepper's "Identity Theory" solution to the problem is now seen as not necessarily clarifying for the question of dualism. Residual asymmetrical dualism is proposed as a theory offering one very good way to think about this set of problems in a variety of modes of inquiry. These include neurophysiological research on the amygdala by LeDoux, research in the phenonenon (...) of hearing and learning while under general anesthetic, Gendlin's methods of focusing upon the body during therapeutic procedures and during creative composition of poetry, and Dewey's position concerning "primary experience" versus a "secondary pseudo-environment" inhabited by the civilized human. Residual asymmetrical dualism is not a value-neutral theory: it is based on a determination that bodily intelligence must ultimately guide mental functioning if survival and well-being are to be secured. It leads to take actions within society to carry out whatever steps are needed to alleviate the mind-body split whenever such a split is harmful to human interaction. (shrink)

There are many controversial theses about intrinsicness and duplication. The first aim of this paper is to introduce a puzzle that shows that two of the uncontroversial sounding ones can’t both be true. The second aim is to suggest that the best way out of the puzzle requires sharpening some distinctions that are too frequently blurred, and adopting a fairly radical reconception of the ways things are.

Fodor’s asymmetric-dependence theory of content is probably the best known and most developed causal or informational theory of mental content. Many writers have attempted to provide counterexamples to Fodor’s theory. In this paper, I offer a more fundamental critique. I begin by attacking Fodor’s view of the dialectical situation. Fodor’s theory is cast in terms of laws covering the occurrence of an individual thinker’s mental symbols. I show that, contrary to Fodor’s view, we cannot restrict consideration to hypothetical cases in (...) which his conditions for content are satisfied, but must consider whether the relevant laws exhibit the specified asymmetric-dependence relations in actual cases. My central argument is that the laws that the theory requires do not in fact exhibit the appropriate asymmetric-dependence relations. I show that, in general, part of the mechanism for the crucial, supposedly content-determining law for a mental symbol is not shared by the mechanisms for the other laws covering the occurrence of the same mental symbol. As a result, the former law can be eliminated (by eliminating the non-overlapping part of the mechanism) without eliminating the latter laws. The latter laws do not asymmetrically depend on the former law. (shrink)

Two related asymmetries have been discussed in relation to the ethics of creating new lives: First, we seem to have strong moral reason to avoid creating lives that are not worth living, but no moral reason to create lives that are worth living. Second, we seem to have strong moral reason to improve the wellbeing of existing lives, but, again, no moral reason to create lives that are worth living. Both asymmetries have proven very difficult to account for in any (...) coherent moral framework. I propose an impersonal population axiology to underpin the asymmetries, which sidesteps the problematic issue of whether or not people can be harmed or benefited by creation or non-creation. This axiology yields perfect asymmetry from a deliberative perspective, in terms of expected value. The axiology also yields substantial asymmetry for large and realistic populations in terms of their actual value, beyond deliberative relevance. (shrink)
