Logics of public communications

Multi-modal versions of propositional logics S5 or S4—commonly accepted as logics of knowledge—are capable of describing static states of knowledge but they do not reflect how the knowledge changes after communications among agents. In the present paper (part of broader research on logics of knowledge and communications) we define extensions of the logic S5 which can deal with public communications. The logics have natural semantics. We prove some completeness, decidability and interpretability results and formulate a general method that solves certain kind of problems involving public communications—among them well known puzzles of Muddy Children and Mr. Sum & Mr. Product. As the paper gives a formal logical treatment of the operation of restriction of the universe of a Kripke model, it contributes also to investigations of semantics for modal logics.

Analyticity and Justification in Frege

That there are analytic truths may challenge a principle of the homogeneity of truth. Unlike standard conceptions, in which analyticity is couched in terms of “truth in virtue of meanings”, Frege’s notions of analytic and a priori concern justification, respecting a principle of the homogeneity of truth. Where there is no justification these notions do not apply, Frege insists. Basic truths and axioms may be analytic (or a priori), though unprovable, which means there is a form of justification which is not (deductive) proof. This is also required for regarding singular factual propositions as a posteriori. A Fregean direction for explicating this wider notion of justification is suggested in terms of his notion of sense (Sinn)—modes in which what the axioms are about are given—and its general epistemological significance is sketched.     

The (near) necessity of alternate possibilities for moral responsibility

Harry Frankfurt has famously criticized the principle of alternate possibilities—the principle that an agent is morally responsible for performing some action only if able to have done otherwise than to perform it—on the grounds that it is possible for an agent to be morally responsible for performing an action that is inevitable for the agent when the reasons for which the agent lacks alternate possibilities are not the reasons for which the agent has acted. I argue that an incompatibilist about determinism and moral responsibility can safely ignore so-called “Frakfurt-style cases” and continue to argue for incompatibilism on the grounds that determinism rules out the ability to do otherwise. My argument relies on a simple—indeed, simplistic—weakening of the principle of alternate possibilities that is explicitly designed to be immune to Frankfurt-style criticism. This alternative to the principle of alternate possibilities is so simplistic that it will no doubt strike many readers as philosophically fallow. I argue that it is not. I argue that the addition of one highly plausible premise allows for the modified principle to be employed in an argument for incompatibilism that begins with the observation that determinism rules out the ability to do otherwise. On the merits of this argument I conclude that deterministic moral responsibility is impossible and that Frankfurt’s criticism of the principle of alternate possibilities—even if successful to that end—may be safely ignored.

Lab Work Goes Social,and Vice Versa: Strategising Public Engagement Processes

Midstream modulation is a form of public engagement with science which benefits from strategic application of science and technology studies (STS) insights accumulated over nearly 20 years. These have been developed from STS researchers’ involvement in practical engagement processes and research with scientists, science funders, policy and other public stakeholders. The strategic aim of this specific method, to develop what is termed second-order reflexivity amongst scientist-technologists, builds upon and advances earlier more general STS work. However this method is focused and structured so as to help generate such reflexivity—over the ‘upstream’ questions which have been identified in other STS research as important public issues for scientific research, development and innovation—amongst practising scientists-technologists in their specialist contexts (public or private, in principle). This is a different focus from virtually all such previous work, and offers novel opportunities for those key broader issues to be opened up. The further development of these promising results depends on some important conditions such as identifying and engaging research funders and other stakeholders like affected publics in similar exercises. Implementing these conditions could connect the productive impacts of midstream modulation with wider public engagement work, including with ‘uninvited’ public engagement with science. It would also generate broader institutional and political changes in the larger networks of institutional actors which constitute contemporary technoscientific innovation and governance processes. All of these various broader dimensions, far beyond the laboratory alone, need to be appropriately open, committed to democratic needs, and reflexive, for the aims of midstream modulation to be achieved, whilst allowing specialists to work as specialists.     

Conceptual representations in goal-directed decision making

Emerging evidence suggests that the long-established distinction between habit-based and goal-directed decision-making mechanisms can also be sustained in humans. Although the habit-based system has been extensively studied in humans, the goal-directed system is less well characterized. This review brings to that task the distinction between conceptual and nonconceptual representational mechanisms. Conceptual representations are structured out of semantic constituents (concepts)—the use of which requires an ability to perform some language-like syntactic processing. Decision making—as investigated by neuroscience and psychology—is normally studied in isolation from questions about concepts as studied in philosophy and cognitive psychology. We ask what role concepts play in the “goal-directed” decision-making system. We argue that one fruitful way of studying this system in humans is to investigate the extent to which it deploys conceptual representations.     

Blame and Avoidability: A Reply to Otsuka

In a fascinating recent article, Michael Otsuka seeks to bypass the debates about the Principle of Alternative Possibilities by presenting and defending a different, but related, principle, which he calls the “Principle of Avoidable Blame.” According to this principle, one is blameworthy for performing an act only if one could instead have behaved in an entirely blameless manner. Otsuka claims that although Frankfurt-cases do undermine the Principle of Alternative Possibilities, they do not undermine the Principle of Avoidable Blame. In this brief paper, we offer a critical discussion of the core of Otsuka’s argument, especially the claim that his favored principle cannot be refuted by Frankfurt-cases. We do not believe that Otsuka has offered good reason to suppose that the Principle of Avoidable Blame—and the related incompatibilism—fares any better than the original Principle of Alternative Possibilities.     

Spurious Causal Kinds: A Problem for the Causal-Power Conception of Kinds

There is an assumption common in the philosophy of mind literature that kinds in our sciences—or causal kinds, at least—are individuated by the causal powers that objects have in virtue of the properties they instantiate. While this assumption might not be problematic by itself, some authors take the assumption to mean that falling under a kind and instantiating a property amount to the same thing. I call this assumption the “Property-Kind Individuation Principle”. A problem with this principle arises because there are cases where we can sort objects by their possession of common causal powers, and yet those objects do not intuitively form a causal kind. In this short note, I discuss why the Property-Kind Individuation Principle is thus not a warranted metaphysical assumption.     

The diversified neighbourhood in western europe and the united states

Many politicians in Western societies assume that strong concentrations of public housing have a debilitating effect on the residents and produce high social costs. The general expectation is that mixed housing projects can help overcome integration problems. In the United States, Belgium, France, Sweden, and the Netherlands, opportunities to mix neighbourhoods vary due to different traditions in housing, as well as specific institutional and socioeconomic conditions. In this comparative article we show that yet another parameter—the predominant view on integration and multiculturalism in each country—is relevant when explaining differences in antisegregation strategies.     

A Dilemma for Higher-Order Theories of Consciousness

Higher Order theories of consciousness have their fair share of sympathisers, but the arguments mustered in their support are—to my mind—unduly persuasive. My aim in this paper is to show that Higher Order theories cannot accommodate the possibility of misrepresentation without either falling into contradiction, or collapsing into a First-Order theory. If this diagnosis is on the right track, then Higher Order theories—at least in the specific versions here considered—fail to give an account of what they set out to explain: what is distinctive of ‘conscious’ phenomena.     

Charged experiences of natural environments

Natural environments often generate experiences that combine great emotional and moral power—“charged” experiences. Their characteristics are explored through writings that capture them convincingly. They appear to have a perceptual character. Perception of the scene is invested with a sense of something beyond it, and much bigger. It may be God, or immensity in time or space, or the essence of a nation. This encounter is often connected with moral authority. A recurring theme is the sense that environment and the things in it—including the observer—are a self-similar pattern. People are not passive recipients of these experiences. They seek them out. Evoking the environment in words can often evoke the charged experience too—at least in part. The material suggests tasks for psychologists—most simply, finding systematic ways to describe these experiences. That may help other environmental disciplines, which face difficulty characterising the dimension of response. Theoretically, the material raises questions about the representations generated by perceptual processes. The observation that powerful moral imperatives seem to be given in the act of perceiving is also suggestive for the psychology of morality. Culture certainly plays a part in charged responses, but landscapes have the power to be invested with an emotional and moral charge where other stimuli may not. I am indebted to Helen Ross for provoking this article; to Bert Hodges, Eamonn Hughes, David Hale and most particularly to Edna Longley for ideas and examples; and to Noel Sheehy for encouragement. They cannot be blamed for my misunderstandings.

The Hope,Promise, and Possibility of Psychotherapy

In this paper, five values—diversity, science, education, practice, and spirit—(a) are examined within the professional context of psychotherapy, (b) are presented as forming the foundation of much if not all that is psychotherapy, and (c) are considered as binding values that join us as a community of practicing, theorizing, and researching psychotherapists. Some of the positives of each value are reviewed. Diversity has heightened our sensitivity to and respect for individual and cultural differences. Science has kept us focused on empirically challenging and empirically informing our practice. Education has maintained emphasis on providing solid training/supervision in psychotherapy and transmitting its culture. Practice has provided us with opportunities to increasingly implement and expand on our role as helpers and healers. Spirit has been the guiding light—the heart and soul—that supports, infuses and informs all of our therapeutic endeavors and gives them meaning. What follows is a celebration of sorts—(a) capturing some of what we have done and are doing right in psychotherapy, (b) reflecting some of the weight of those “right” efforts, and (c) conveying some of the inherent hope, promise, and possibility that forever guide us in our work.     

Taking Law Seriously: Starting Points of the Hart/Devlin Debate*

The famous mid-20th century debate between Patrick Devlin and Herbert Hart about the relationship between law and morality addressed the limits of the criminal law in the context of a proposal by the Wolfenden Committee to decriminalize male homosexual activity in private. The original exchanges and subsequent contributions to the debate have been significantly constrained by the terms in which the debate was framed: a focus on criminal law in general and sexual offences in particular; a preoccupation with the so-called “harm principle,” a sharp delineation of the realms of law and morality, and a static conception of the relationship between them. This article explores the limitations imposed by these various starting-points and argues for a holistic and symbiotic understanding of the relationship between law and morality. * Thanks to Tony Connolly, Leighton McDonald and Niki Lacey for penetrating and suggestive comments on previous versions.     

The theory of the organism-environment system: III. Role of efferent influences on receptors in the formation of knowledge

The present article is an attempt to give—in the frame of the theory of the organism-environment system (jarvilehto, 1998a)—a new interpretation to the role of efferent influences on receptor activity and to the functions of senses in the formation of knowledge. It is argued, on the basis of experimental evidence and theoretical considerations, that the senses are not transmitters of environmental information, but create a direct connection between the organism and the environment, which makes the development of a dynamic living system, the organism-environment system, possible. In this connection process, the efferent influences on receptor activity are of particular significance because, with their help, the receptors may be adjusted in relation to the parts of the environment that are most important in achieving behavioral results. Perception is the process of joining of new parts of the environment to the organism-environment system; thus, the formation of knowledge by perception is based on reorganization (widening and differentiation) of the organism-environment system, and not on transmission of information from the environment. With the help of the efferent influences of receptors, each organism creates its own peculiar world that is simultaneously subjective and objective. The present considerations have far-reaching influences as well on experimental work in neurophysiology and psychology of perception as on philosophical consideration of knowledge formation.     

An ethics of expertise based on informed consent

Ethicists widely accept the notion that scientists have moral responsibilities to benefit society at large. The dissemination of scientific information to the public and its political representatives is central to many of the ways in which scientists serve society. Unfortunately, the task of providing information can often give rise to moral quandaries when scientific experts participate in politically charged debates over issues that are fraught with uncertainty. This paper develops a theoretical framework for an “ethics of expertise” (EOE) based on the notion that scientists have responsibilities to provide information in a way that promotes autonomous decision-making on the part of the public and its representatives. Moreover, insofar as the principle of informed consent has developed in biomedical ethics as a way for physicians to promote autonomous decision-making on the part of their patients, this paper suggests that the informed-consent concept may suggest a set of criteria and guidelines that can help scientists to fulfill their similar ethical responsibilities to the public. In order to illustrate how the resulting EOE could provide practical guidance for scientific experts, the paper examines a case study involving the dissemination of information about the low-dose biological effects of toxic chemicals and carcinogens.     

A baldrige process for ethics?

In this paper we describe and explore a management tool called the Caux Round Table Self-Assessment and Improvement Process (SAIP). Based upon the Caux Round Table Principles for Business — a stakeholder-based, transcultural statement of business values — the SAIP assists executives with the task of shaping their firm’s conscience through an organizational self-appraisal process. This process is modeled after the self-assessment methodology pioneered by the Malcolm Baldrige National Quality Award Program. After briefly describing the SAIP, we address three topics. First, we examine similarities and differences between the Baldrige approach to corporate self-assessment and the self-assessment process utilized within the SAIP. Second, we report initial findings from two beta tests of the tool. These illustrate both the SAIP’s ability to help organizations strengthen their commitment to ethically responsible conduct, and some of the tool’s limitations. Third, we briefly analyze various dimensions of the business scandals of 2001–2002 (Enron, WorldCom, Tyco, etc.) in light of the ethical requirements articulated with the SAIP. This analysis suggests that the SAIP can help link the current concerns of stakeholders — for example, investors and the general public — to organizational practice, by providing companies with a practical way to incorporate critical lessons from these unfortunate events. An earlier version of this paper was presented at the “Ethics and Social Responsibility in Engineering and Technology” meeting, New Orleans, 2003.     

Nanotechnology — A new field of ethical inquiry?

Parallel to the public discussion on the benefits and risks of nanotechnology, a debate on the ethics of nanotechnology has begun. It has been postulated that a new “nano-ethics” is necessary. In this debate, the — positive as well as negative — visionary and speculative innovations which are brought into connection with nanotechnology stand in the foreground. In this contribution, an attempt is made to discover new ethical aspects of nanotechnology in a more systematic manner than has been the case. It turns out that there are hardly any completely new ethical aspects raised by nanotechnology. It is much rather primarily a case of gradual shifts of emphasis and of relevance in questions which, in principle, are already known and which give reason for ethical discussions on nanotechnology. In a certain manner, structurally novel ethical aspects arise through the important role played by visions in the public discourse. New questions are also posed by the fact that previously separate lines of ethical reflection converge in the field of nanotechnology. The proposal of an independent “nano-ethics”, however, seems exaggerated.     

Reconsidering the Role of Bridge Laws In Inter-Theoretical Reductions

The present paper surveys the three most prominent accounts in contemporary debates over how sound reduction should be executed. The classical Nagelian model of reduction derives the laws of the target-theory from the laws of the base theory plus some auxiliary premises (so-called bridge laws) connecting the entities of the target and the base theory. The functional model of reduction emphasizes the causal definitions of the target entities referring to their causal relations to base entities. The new-wave model of reduction deduces not the original target theory but an analogous image of it, which remains inside the vocabulary of the base theory. One of the fundamental motivations of both the functional and the new-wave model is to show that bridge laws can be evaded. The present paper argues that bridge laws—in the original Nagelian sense—are inevitable, i.e. that none of these models can evade them. On the one hand, the functional model of reduction needs bridge laws, since its fundamental concept, functionalization, is an inter-theoretical process dealing with entities of two different theories. Theoretical entities of different theories (in a general heterogeneous case) do not have common causal relations, so the functionalization of an entity—without bridge laws—can only be executed in the framework of its own theory. On the other hand, the so-called images of the new-wave account cannot be constructed without the use of bridge laws. These connecting principles are needed to guide the process of deduction within the base theory; without them one would not be able to recognize if the deduced structure was an image of the target theory.     

The Burden of Proof and Its Role in Argumentation

The notion of “the burden of proof” plays an important role in real-world argumentation contexts, in particular in law. It has also been given a central role in normative accounts of argumentation, and has been used to explain a range of classic argumentation fallacies. We argue that in law the goal is to make practical decisions whereas in critical discussion the goal is frequently simply to increase or decrease degree of belief in a proposition. In the latter case, it is not necessarily important whether that degree of belief exceeds a particular threshold (e.g., ‘reasonable doubt’). We explore the consequences of this distinction for the role that the “burden of proof” has played in argumentation and in theories of fallacy.     

Justification and awareness

In Justification Without Awareness, Michael Bergmann attacks Internalism and Mentalism. His attack on Internalism refutes some versions of an awareness requirement for justification but leaves another standing and well-motivated. His attack on Mentalism, while successful, leaves us with a difficult question—what non-mental features play a role in determining justification?—that his own externalist theory fails to answer correctly.
