Sociological propositions about the workings of cognition are rarely specified or tested, but are of central relevance to studies of culture, social judgment, and social movements. This paper draws out lessons of recent work from sociological theory, cognitive science, psychology, and neuroscience on the embodied nature of knowledge and thought, and develops implications of these lessons for cultural and cognitive sociology. Knowledge ought to be conceived of as fundamentally embodied, because sensory information is a fundamental component of experience as it (...) is stored in long-term memory, and because bodily responses and intuitions often precede reflexive or strategic thought. I argue that the challenge of embodied knowledge for cultural sociology is threefold: to develop cultural theories of motivation; to specify the ways in which the body structures discourses endogenously; and to specify how embodied motivations and embodied discourses interact.

Multiple studies show that periodic reanalysis of genomic test results held by clinical laboratories delivers significant increases in overall diagnostic yield. However, while there is a widespread consensus that implementing routine reanalysis procedures is highly desirable, there is an equally widespread understanding that routine reanalysis of individual patient results is not presently feasible to perform for all patients. Instead, researchers, geneticists and ethicists are beginning to turn their attention to one part of reanalysis—reinterpretation of previously classified variants—as a means of (...) achieving similar ends to large-scale individual reanalysis but in a more sustainable manner. This has led some to ask whether the responsible implementation of genomics in healthcare requires that diagnostic laboratories routinely reinterpret their genomic variant classifications and reissue patient reports in the case of materially relevant changes. In this paper, we set out the nature and scope of any such obligation, and analyse some of the main ethical considerations pertaining to a putative duty to reinterpret. We discern and assess three potential outcomes of reinterpretation—upgrades, downgrades and regrades—in light of ongoing duties of care, systemic error risks and diagnostic equity. We argue against the existence of any general duty to reinterpret genomic variant classifications, yet we contend that a suitably restricted duty to reinterpret ought to be recognised, and that the responsible implementation of genomics into healthcare must take this into account.

The objective of the text is to propose an interpretation of Hume's works that allows another way of refusing contractualism, different from the "official" refusal, and which is based (the new one) on the concept of artifice, which is extremely different from the artifice created by the contractualists, whose opposition the tradition of commentators of Humean political philosophy, generally, do not refer to, when it is the case of refusing contractualism.

Do mereological fusions have their parts necessarily? None of the axioms of non-modal formulations of classical mereology appear to speak directly to this question. And yet a great many philosophers who take the part-whole relation to be governed by classical mereology seem to assume that they do. In addition to this, many philosophers who make allowance for the part-whole relation to obtain merely contingently between a part and a mereological fusion tend to depart from non-modal formulations of classical mereology at (...) least when it comes to the axiom of Unique Fusion, which states that no two different mereological fusions ever fuse exactly the same objects. This is no coincidence. There are reasons of principle why one’s adherence to classical mereology should exert some pull towards the view that mereological fusions have their parts necessarily. There is, however, no direct route from the combination of classical mereology and propositional modal logic to the hypothesis that the part-whole relation obtains necessarily between a part and a mereological fusion. In order to bridge between a modal formulation of classical mereology and the hypothesis that fusions have their parts necessarily, one needs to strengthen the axiom of Unrestricted Fusion in a way that is agreeable to many philosophers on both sides of the debate.

Several philosophers have argued recently that semantic properties do play a causal role. 1 It is our view that none of these arguments are satisfactory. Our aim is to reveal some of the deficiencies of these arguments, and to reassess the question in our own way. In section 1, we shall explain in more detail what is involved in the pretheoretical idea of a causally efficacious property and so provide a fuller sense of the issue. In section 2 we shall (...) discuss Fodor's and Kim's arguments that the semantic properties of mental events are causally efficacious. Their tactic is to articulate sufficient conditions for the causal efficacy of a property, and then apply these conditions to the psychological properties under consideration. We shall show that both formulations are inadequate. However, each account can remedy some of the defects of the other. We shall argue that by putting the two together, and modifying this combined account in certain ways, we can arrive at something that might just pass as a general sufficient condition for causal efficacy. We believe that the question of causal efficacy of content is best approached as a question in the philosophy of science. If one wants to know whether a given species of property is efficacious, the most productive strategy is to find a science that investigates the properties and examine the role they are assigned. In keeping with this attitude we shall restrict our discussion to the notion of content deployed within cognitive science. In section 3 we examine the role of content in cognitive science and discuss whether this role suits content to the conditions on efficacy articulated in section two. Our conclusion will be conditional and hedged: on certain views of cognitive science, content will meet the sufficient condition for efficacy. If other views are correct, the question remains open.

Groups are ubiquitous in our lives. But while some of them are highly structured and appear to support a shared intentionality and even a shared agency, others are much less cohesive and do not seem to demand much of their individual members. Queues, for example, seem to be, at a given time, nothing over and above some individuals as they exemplify a certain spatial arrangement. Indeed, the main aim of this paper is to develop the more general thought that at (...) a given time, a group is nothing over and above some individual members as they exemplify a certain complex condition. The general conception of groups that emerges is able to accommodate a variety of constraints on a reasonable answer to the question of what are groups. (shrink)

Philosophers often explain what could be the case in terms of what is, in fact, the case at one possible world or another. They may differ in what they take possible worlds to be or in their gloss of what is for something to be the case at a possible world. Still, they stand united by the threat of paradox. A family of paradoxes akin to the set-theoretic antinomies seem to allow one to derive a contradiction from apparently plausible principles. (...) Some of them concern the interaction between propositions and worlds, and they appear to afford the means to map classes of propositions into propositions – or, likewise, classes of worlds into worlds – in a one-to-one fashion that leads to contradiction. Yet another family of paradoxes threaten the view that whatever could exist does, in fact, exist, which is in line with modal realism, for example. This article aims to survey and identify the source of each family of paradoxes as well as to outline some responses to them. (shrink)

This paper explores several topics related to Woodin’s HOD conjecture. We improve the large cardinal hypothesis of Woodin’s HOD dichotomy theorem from an extendible cardinal to a strongly compact cardinal. We show that assuming there is a strongly compact cardinal and the HOD hypothesis holds, there is no elementary embedding from HOD to HOD, settling a question of Woodin. We show that the HOD hypothesis is equivalent to a uniqueness property of elementary embeddings of levels of the cumulative hierarchy. We (...) prove that the HOD hypothesis holds if and only if every regular cardinal above the first strongly compact cardinal carries an ordinal definable [Formula: see text]-Jónsson algebra. We show that if the HOD hypothesis holds and HOD satisfies the Ultrapower Axiom, then every supercompact cardinal is supercompact in HOD. (shrink)

Despite progress, discrimination in public health remains a problem. A significant aspect of this problem relates to how medical resources are allocated. The paradigm of quality-adjusted-life-year (QALY) dictates that medical resources should be allocated on the basis of units measured as length of life and quality of life that are expected after the implementation of a treatment. In this article, I discuss some of the ethical shortcomings of QALY, by focusing on some of its flawed moral aspects, as well as (...) the way it relates to discrimination on the basis of age, race, and disability status. I argue that while this approach seeks to maximize efficiency, it does not place sufficient value on the preservation of life itself. Even more concerning is the fact that the use of QALY disproportionately harms minorities. While QALY is a well-intentioned approach to the allocation of scarce healthcare resources, new alternatives must be sought. (shrink)

Perceptual learning is characterized by long-term changes in perception as a result of practice or experience. In this paper, I argue that through perceptual learning we can become newly sensitive to basic perceptual features. First, I provide a novel account of basic perceptual features. Then, I argue that evidence from experience-based plasticity suggests that basic perceptual features can be learned. Lastly, I discuss the common scientific and philosophical view that perceptual learning comes in at least four varieties: differentiation, unitization, attentional (...) weighting and stimulus imprinting (Goldstone 1998, Connolly 2019). Becoming newly sensitive to basic perceptual features, I argue, does not fit into any of these categories. This paper’s contribution to the literature is twofold. First, I present a novel view of basic perceptual features which can be used in subsequent theorizing. Second, I show that learning basic perceptual features, since it does not fit into this standardized taxonomy, constitutes an underappreciated form of perceptual learning. This result has important implications for recent discussions in the philosophy of perception and epistemology. (shrink)

El Estado de Hegel es el Estado de Derecho. Sin embargo en su Filosofía del Derecho se encuentran fundamentos decisivos para una teoría del Estado Social. Siguiendo el hilo de las Líneas fundamentales de la Filosofía del Derecho, se empieza por ver el derecho al bienestar, tal como se formula en la Moralidad (1). En la familia aparece el derecho de los hijos "de ser alimentados y educados" (2). El Derecho al bienestar se concreta en la sociedad civil (3), se (...) hace posible en el sistema de las necesidades (3.1.) y efectivo en la policía y la corporación (3.2 y 3.3), que ejercen funciones de suplencia de la familia.

Apologizing for Socrates places some of the Platonic and Xenophontic writings in the context of contemporary controversies over Socrates, providing a perspective in which many of the philosophic and literary features of the text can be explained. In addition, it sheds light on the apologetic techniques used by Plato and Xenophon.

Part I of Frege’s Grundgesetze is devoted to the “exposition [Darlegung]” of his formal system.

David Kaplan observed in Kaplan that the principle \\) cannot be verified at a world in a standard possible worlds model for a quantified bimodal propositional language. This raises a puzzle for certain interpretations of the operator Q: it seems that some proposition p is such that is not possible to query p, and p alone. On the other hand, Arthur Prior had observed in Prior that on pain of contradiction, ∀p is Q only if one true proposition is Q (...) and one false proposition is Q. The two observations are related: ∀p is elusive in that it is not possible for the proposition to be uniquely Q. Kaplan based his model-theoretic observation on Cantor’s theorem, but there is a less well-known link between this simple set-theoretic observation and Prior’s remark. We generalize the link to develop a heuristic designed to move from Cantor’s theorem to the observation that a variety of sentences of the bimodal language express propositions that cannot be Q uniquely. We highlight the analogy between some of these results and some set-theoretic antinomies and suggest that the phenomenon is richer than one may have anticipated. (shrink)

A finalidade explícita na arquitetura e ênfase na utilidade, no aspecto de uma aplicação prática, intrigou filósofos alemães como Immanuel Kant e August Schlegel. O entrelaçamento entre beleza e finalidade na arquitetura fora notado cedo por Marco Vitrúvio Polião, que aponta utilidade, solidez e beleza como características fundamentais da obra arquitetônica. Segundo Guyer, a partir de Kant, o pensamento filosófico sobre a arquitetura começa a apresentar um distanciamento em relação a Vitrúvio, de modo que, mesmo sem total renúncia à tríade (...) vitruviana no pensamento de Kant, este defende ser a característica principal da arquitetura representar ideias estéticas. A tese de Guyer aponta o desenvolvimento desse ponto de Kant em Schelling, Hegel e Schopenhauer, todavia com uma lacuna: August Schlegel, fundador do primeiro sistema de belas artes com sua Kunstlehre. Buscaremos aprofundar como a tese de Guyer não só é válida, mas ganha mais solidez no caso de August Schlegel e do papel que este confere à imaginação na arquitetura. Após a indicação de elementos vitruvianos e pós-vitruvianos em Kant e Schlegel, indicaremos as divergências entre ambos na apreciação da arquitetura, a partir de suas articulações entre arquitetura e finalidade.

In this paper I want to discuss Bernard Bosanquet’s idea of the nature and role of feeling and emotion in art.

Achille Mbembe’s latest book addresses some of the existential concerns of the modern age and the power structures that have shaped them. Modernity’s allure has created a false belief in the idea of progress while concealing a destructive streak in human activities. He warns that there is trouble ahead unless humans chart a different course. But is this the lamentation of a Jeremiad or a timely intervention in the current state of the world?

Abordaremos como a ‘fé racional pura’ de Kant surge no contexto da ligação necessária entre moralidade e felicidade (o conceito kantiano de sumo Bem). Em seguida, abordaremos a recepção deste filósofo por Feuerbach, que ora se serve de Kant, ora o critica, principalmente pela redução da religião à moralidade promovida pelo filósofo de Königsberg – haja vista que Feuerbach enfatiza o papel do sentimento na fé. Finalmente, confrontaremos Feuerbach com Kant, tentando observar qual é a sede da fé para cada (...) autor: a razão pura e sua demanda de integração necessária da moralidade com a felicidade (Kant) ou o temor diante das forças da natureza somado ao desejo de imortalidade (Feuerbach). O que buscamos demonstrar é como, a nosso ver, tanto a razão quanto a afetividade estão em jogo na fé. A questão é a compreensão acerca de qual nível de consciência e de qual faculdade do ânimo se considera o ser humano. Busca-se também, ao longo da exposição, refletir sobre como Kant, ainda que tenha buscado fundar uma moral a priorística, acabou inserindo nela vários elementos históricos e contingentes, como fica nítido pela a influência do Cristianismo.

This chapter develops a semantic theory for maps and situates it within the broader geography of meaning and semiotic significance. The discussion focuses on three central aspects of map semantics: the use of space, line marking, and linguistic tags. It is argued that the treatment of space in maps must be based on geometrical projection from a viewpoint rather than the traditional analysis in terms of spatial isomorphism. The chapter then shows how to integrate the projection-based semantics of maps and (...) the symbolic semantics of markers and tags, within the framework of possible-world semantics. The resulting account addresses issues of accuracy, viewpoint, orientation, and exhaustivity. (shrink)

In [12], Ernst Zermelo described a succession of models for the axioms of set theory as initial segments of a cumulative hierarchy of levelsUαVα. The recursive definition of theVα's is:Thus, a little reflection on the axioms of Zermelo-Fraenkel set theory shows thatVω, the first transfinite level of the hierarchy, is a model of all the axioms ofZFwith the exception of the axiom of infinity. And, in general, one finds that ifκis a strongly inaccessible ordinal, thenVκis a model of all of (...) the axioms ofZF. Doubtless, when cast as a first-order theory,ZFdoes not characterize the structures 〈Vκ,∈∩〉 forκa strongly inaccessible ordinal, by the Löwenheim-Skolem theorem. Still, one of the main achievements of [12] consisted in establishing that a characterization of these models can be attained when one ventures into second-order logic. For let second-orderZFbe, as usual, the theory that results fromZFwhen the axiom schema of replacement is replaced by its second-order universal closure. Then, it is a remarkable result due to Zermelo that second-orderZFcan only be satisfied in models of the form 〈Vκ,∈∩〉 forκa strongly inaccessible ordinal. (shrink)

Although recent trends in politics and media make it appear that conspiracy theories are on the rise, in fact they have always been present, probably because they are sustained by natural dispositions of the human brain. This is also the case with medical conspiracy theories. This article reviews some of the most notorious health-related conspiracy theories. It then approaches the reasons why people believe these theories, using concepts from cognitive science. On the basis of that knowledge, the article makes normative (...) proposals for public health officials and health workers as a whole, to deal with conspiracy theories, in order to preserve some of the fundamental principles of medical ethics.

In this paper we show that first-order languages extended with partially ordered connectives and partially ordered quantifiers define, under a certain interpretation, their own truth-predicate. The interpretation in question is in terms of games of imperfect information. This result is compared with those of Kripke and Feferman.

We show from an abstract comparison principle that the Mitchell order is linear on sufficiently strong ultrafilters: normal ultrafilters, Dodd solid ultrafilters, and assuming GCH, generalized normal ultrafilters. This gives a conditional answer to the well-known question of whether a [Formula: see text]-supercompact cardinal [Formula: see text] must carry more than one normal measure of order 0. Conditioned on a very plausible iteration hypothesis, the answer is no, since the Ultrapower Axiom holds in the canonical inner models at the finite (...) levels of supercompactness. (shrink)

Concepts of decision, choice, decision-maker, and decision-making are common practical tools in both social science and natural science, on which scientific knowledge, policy implications, and moral recommendations are based. In this article I address three questions. First, I look into how present-day social scientists and natural scientists use decision/choice concepts. What are they used for? Second, scientists may differ in the application of decision/choice to X, and they may explicitly disagree about the applicability of decision/choice to X. Where exactly do (...) these disagreements lie? Third, I ask how scientists should use decision/choice concepts. What are they correctly and incorrectly used for? I argue that scientists must responsibly attend to a methodological demand: you have to have a principled, non-ad hoc, well-argued-for way of telling where decision/choice applicability ends. Thus, I aim to minimize the risk of conceptual stretching and foster responsible conceptual practices in a large body of scientific work. (shrink)

To Serve With Honor should be required reading for all members of the officer corps of the United States military.

The death of George Floyd in May 2020 sparked an unprecedented global wave of protests that appeared to mark a turning point in the battle against racial injustice. But protests against racism are not new; each comes and soon passes into the archives of history, leaving few lasting changes in its wake. What was different about the death of Floyd was that the graphic manner of its unfolding was captured on film: the slow act of wilful suffocation, and how the (...) entire world was seemingly invited to witness the torment and the execution of this man, in broad daylight, even as he cried I can't breathe. However, this discussion attempts to move beyond that moment of death, the protests that followed and the distracting debate about statues and monuments to argue that the death of Floyd must be seen as the culmination of the process of systemic and structural racism. It aims to show how racism shifted from the black body as the visible and material target of racial oppression to air/breath, and how suffocation became the characteristic feature as well as the weapon of contemporary racial injustice.

In lieu of an abstract, here is a brief excerpt of the content:A NOTE ON THE RELATION OF PACIFISM AND JUST-WAR THEORY: IS THERE A THOMISTIC CONVERGENCE? 1 GABRIEL PALMER-FERNANDEZ Youngstown State University Youngstown, Ohio FOR CENTURIES, the moral analysis of war began with a consideration of a set of principles which together form the doctrine of the just-war and with a rejection of pacifism. However, several recent studies by Catholic moralists argue that pacifism and just-war theory have much (...) in common and converge in at least one morally important way-namely, they share a presumption against violence. In this note I want to consider whether or not classical just-war theory gives us reason to accept this claim. I will give evidence against it, and suggest that the "original just-war question," as James Turner Johnson calls it, does not begin with aprohibitive presumption or some equivalent constraint on action. If we are to speak of a presumption in classical just-war theory, it is that justice be done for the sake of the common good. Up to very recent times, those Christian denominations which Ernst Troeltsch called the "church-type" (Lutheran, Anglican, Calvinist, and Roman Catholic) upheld a " two-tiered " or "double" morality. A "vocational" pacifism was required of clerical ranks, and the individual Christian was obligated to take up arms for the sake of the common good. For example, prior to the Second Vatican Council, Roman Catholic teaching on war rejected conscientious objection to all war (i.e., pacifism) as an option for Catholics. Manuals of moral theology prior to Vatican 1 I wish to acknowledge the very helpful and detailed comments provided by Richard B. Miller to an earlier version of this paper. 247 248 GABRIEL PALMER-FERNANDEZ II did prohibit the soldier from fighting in an unjust war and made room for subjective doubt about the justice of a particular war. But the consensus among Catholic theologians was both wide and deep. Pacifism for individual Christians did not have any moral-theological justification. It was, in fact, a grave moral error. In spite of this, Vatican II called for a " completely fresh reappraisal of war." 2 The policy of obliterating whole cities enacted during World War II, coupled with the development of nuclear and other indiscriminate weapons of destruction (e.g., incapacitating gases, biological weapons, etc.) and the instability of superpower relations, created an unprecedented condition for which traditional teachings on war seemed woefully inadequate, if not morally dangerous. A new, more far-reaching perspective was needed. And this was to allow for individuals the pacifist option as a second and complementary moral doctrine alongside traditional teaching on war.3 As the American Catholic bishops said in their pastoral letter on war and peace : 2 Pastoral Constitution on the Church in the Modern World, in A. Flannery, 0.P., ed., Vatican Council II: The Conciliar and Post Conciliar Documents (Collegeville, Minn. : Liturgical Press, 1975), par. 80. 3 This development in contemporary Roman Catholic teaching on war and peace has been challenged with considerable force by George Weigel in what has become one of the most controversial studies on the subject. In Tranquillitas Ordinis: The Present Failure and Future Promise of American Catholic Thought on War and Peace (New York: Oxford University Press, 1987), Weigel advances several arguments which are meant to correct what he insists is a failure among Catholic ethicists in the U.S. to develop their tradition, and, indeed, an abandonment of their heritage. " At the level of moral theory," Weigel maintains, "the two classic positions [just-war theory and pacifism] are not reconcilable. The attempt to merge them... tends to corrupt both traditions. Pacifists end up making judgments on military strategy and tactics, and just-war theorists are held accountable to arguments they previously declined to accept.... The net result is to bifurcate morality and politics, and to abandon attempts to apply the tradition of reason to the limit case of the use of armed force in the defense of values-which is precisely the result Murray most feared in his strictures against moralism" (251). For David Hollenbach's rebuttal, see his review essay, "War and Peace in American Catholic Thought: A Heritage Abandoned? " Theological Studies 48 (1987) : 711-727... (shrink)

Moral repair is an important way for firms to heal moral relationships with stakeholders following a transgression. The concept is rooted in recognition theory, which is often used to develop normative perspectives and prescriptions, but the same theory has also propelled a view of moral repair as premised on negotiation between offender and victim(s), which involves the complex social construction of the transgression and the appropriate amends. The tension between normative principles and socioconstructivist implementation begs the question how offending firms (...) should approach moral repair. Addressing this question, we develop a two-level conceptualization of moral repair, distinguishing between procedural and substantive levels of practice, which accommodate normativity and socioconstructivism, respectively. In so doing, we enrich the literature by 1) promoting conceptual clarity, 2) refining understanding of the moral repair process, and 3) suggesting the use of a unified, configurational approach to studying (nonlinear) relations between amends and moral outcomes.

The Russell–Myhill theorem threatens a familiar structured conception of propositions according to which two sentences express the same proposition only if they share the same syntactic structure and their corresponding syntactic constituents share the same semantic value. Given the role of the principle of universal instantiation in the derivation of the theorem in simple type theory, one may hope to rehabilitate the core of the structured view of propositions in ramified type theory, where the principle is systematically restricted. We suggest (...) otherwise. The ramified core of the structured theory of propositions remains inconsistent in ramified type theory augmented with axioms of reducibility. This is significant because reducibility has been thought to be perfectly consistent with the ramified approach to the intensional antinomies. Nor is the addition of reducibility to ramified type theory sufficient to restore other intensional puzzles such as Prior’s paradox or Kripke’s puzzle about time and thought. (shrink)

In continuation with the New Thought movement that arose in the United States in the 19th Century, there is now a massive self-help industry that markets books and seminars. This industry has also extended to healthcare in the form of positive thinking, i.e., the idea that happy thoughts are essential for health. While some of these claims may seem reasonable and commonsensical, they are not free of problems. This article posits that positive thinking has some ethical underpinnings. Extreme positive thinking (...) may promote alternative forms of medicine that ultimately substitute effective treatment, and this is unethical. The emphasis on positive thinking for cancer patients may be too burdensome for them. Likewise, unrestricted positive thinking is not necessarily good for mental health. After considering the ethics of positive thinking, this article proposes a more realistic approach. (shrink)

This article is a libertarian critique of incest laws. On the basis of the libertarian “harm principle”, one must ask what exactly is the harm that incest brings forth. Traditionally, anthropologists have tried to rationalize the incest taboo in various theories, and lawmakers have used these principles as grounds for the criminalization of incest. These principles are the preservation of family structure, the enhancement of alliances and the avoidance of genetic risks. While I acknowledge that these rationalizations are plausible, I (...) argue that they are still not sufficient grounds for the preservation of incest laws, and consequently, there is an ethical need to reform them.

The paper argues that there are two main kinds of joint action, direct joint bringing about (or performing) something (expressed in terms of a DO-operator) and jointly seeing to it that something is the case (expressed in terms of a Stit-operator). The former kind of joint action contains conjunctive, disjunctive and sequential action and its central subkinds. While joint seeing to it that something is the case is argued to be necessarily intentional, direct joint performance can also be nonintentional. Actions (...) performed by social groups are analyzed in terms of the notions of joint action (basically DO and Stit).A precise semantical analysis of the aforementioned kinds of joint action is given in terms of time-trees. With each participant a tree is connected, and the trees are joined defining joint possible worlds in terms of state-expressing nodes from the trees. Sentences containing DO and Stit are semantically evaluated with respect to such joint possible worlds. Intentional joint actions are characterized in terms of the notion of we-intention (joint intention), characterized formally by means of a special operator. (shrink)

In his article The Foundations of Mathematics (1925) Ramsey was concerned with the nature of the statements of 'pure mathematics' and the way these statements differ from those in empirical sciences. He thought that the answer given to these questions by Hilbert and the formalist school according to which mathematical statements are meaningless formulas, is unsatisfactory for several reasons, which will not be discussed here. He also expressed serious doubts about the intuitionist program developed by Brouwer and Weyl. It is (...) the logicist school of Frege, Russell and Whitehead, which attempted to reduce mathematics to few logical concepts, that came closest to Ramsey’s views, although he was not completely satisfied with it, either.
