Kripke’s argument against functionalism extended to physical computers poses a deep philosophical problem for understanding the standard view of what computers are. The problem puts into jeopardy the definition in the standard view that computers are physical machines for performing physical computations. Indeed, it is entirely possible that, unless this philosophical problem is resolved, we will never have a good understanding of computers and may never know just what they are.

This paper examines relationships between teaching critical thinking and teaching philosophy to adolescents (ages 12–17). The focus is on argumentation, especially on the method used to determine how well the premises of an argument support its conclusion. The method is the method of counterexamples. This article describes the results of teaching this method to adolescents (ages 12–17) who were participants in a summer enrichment program at Rutgers University-Newark, the Rutgers-Merck Summer Bioethics Institute. The participants were to learn about the philosophical (...) ideas underlying current biomedical technologies. The article discusses the basic ideas of argumentation and the method of counterexamples for determining the support that premises give to conclusion for a given argument, and it discusses teaching this method to adolescents. The article describes how to assess that they have properly learned it, and, finally, it closes with a discussion of the cognitive skills adolescents acquire in learning philosophy. Teaching a reliable method of determining argument support for a conclusion prior to teaching philosophy to adolescents results in their achieving a deeper understanding of philosophy. (shrink)

With mind-brain identity theories no longer dominant in philosophy of mind in the late 1950s, scientific materialists turned to functionalism, the view that the identity of any mental state depends on its function in the cognitive system of which it is a part. The philosopher Hilary Putnam was one of the primary architects of functionalism and was the first to propose computational functionalism, which views the human mind as a computer or an information processor. But, in the early 1970s, Putnam (...) began to have doubts about functionalism, and in his masterwork _Representation and Reality_, he advanced four powerful arguments against his own doctrine of computational functionalism. In Gödel, Putnam, and Functionalism, Jeff Buechner systematically examines Putnam's arguments against functionalism and contends that they are unsuccessful. Putnam's first argument uses Gödel's incompleteness theorem to refute the view that there is a computational description of human reasoning and rationality; his second, the "triviality argument," demonstrates that any computational description can be attributed to any physical system; his third, the multirealization argument, shows that there are infinitely many computational realizations of an arbitrary intentional state; his fourth argument buttresses this assertion by showing that there cannot be local computational reductions because there is no computable partitioning of the infinity of computational realizations of an arbitrary intentional state into a single package or small set of packages. Buechner analyzes these arguments and the important inferential connections among them -- for example, the use of both the Gödel and triviality arguments in the argument against local computational reductions -- and argues that none of Putnam's four arguments succeeds in refuting functionalism. _ Gödel, Putnam, and Functionalism_ will inspire renewed discussion of Putnam's influential book and will confirm Representation and Reality as a major work by a major philosopher. Jeff Buechner is Director of the Bioethics Institute and Lecturer in Philosophy at Rutgers University-Newark. (shrink)

In this paper, I examine a key issue affecting trust in the context of a computing environment, as it affects human agents and artificial agents. Specifically, the paper focuses on the role that "resource conservation" plays in an analysis of moral trust and epistemic trust involving agents. I will argue that resource conservation is a necessary condition in the definition of a moral trust relation, that there is a conceptual relationship between a moral trust relation and epistemic trust---that epistemic trust (...) is a necessary condition for moral trust---, and that a moral trust relation might provide a basic mechanism for the realization of ecological rationality in human agents.

Today’s fast-moving, media lifeworld embodies many of the metaphors of its analog predecessors – including those of warfare and conflict. The metaphor of warfare is used to describe everything from corporate marketing strategies to political campaigns, often with harmful consequences. In one way of exploring the front lines of the resulting war on truth, we describe some lessons learned from the experience of military veterans who have actually endured the liminality of combat, and who emerge with what is increasingly termed (...) moral injuries. We use their experience as an analogy for competing narratives in cyberspace, where objective standards of truth and facticity are apparent casualties, and where fake news is emerging as victorious. We then apply models of social construction, specifically the practical theory of the Coordinated Management of Meaning, and the metaphor of jazz improvisation in the context of Schutz’s lifeworld phenomenology as possibly useful, helpful, and hopeful ways of acting into the complexity of truth together.

Every price is set by someone; this is where economics begins. Building on that fundamental idea and on Ayn Rand's philosophy of Objectivism, Objective Economics transforms economics. The thesis of this book is that Ayn Rand's concept of "objective" is the indispensible base of valid economic thought. Consistently applying this idea across the board, the author reaches a general theory of price for the first time in the history of economic thought. This theory of price then provides a valid base (...) for explaining how a free economy functions. Based on facts everyone knows, presented without graphs or higher mathematics, Objective Economics makes accessible to the intelligent layman a clear understanding of how the economy works. For everyone who found college economics impenetrable--and that is just about everyone--this is the book.The thesis of Objective Economics changes everything about economics, including economics' method, the conception of the economy, the meaning of competition, the idea of price, the nature of business costs, the concept of supply, the concept of demand, the law of supply and demand, the theory of price, and the theory of total national output. Overall, as the result of all the preceding, Objective Economics demonstrates that capitalism is the practical economic system. (shrink)

We argue that the notion of trust, as it figures in an ethical context, can be illuminated by examining research in artificial intelligence on multi-agent systems in which commitment and trust are modeled. We begin with an analysis of a philosophical model of trust based on Richard Holton’s interpretation of P. F. Strawson’s writings on freedom and resentment, and we show why this account of trust is difficult to extend to artificial agents (AAs) as well as to other non-human entities. (...) We then examine Margaret Urban Walker’s notions of “default trust” and “default, diffuse trust” to see how these concepts can inform our analysis of trust in the context of AAs. In the final section, we show how ethicists can improve their understanding of important features in the trust relationship by examining data resulting from a classic experiment involving AAs.

Are trust relationships involving humans and artificial agents possible? This controversial question has become a hotly debated topic in the emerging field of machine ethics. Employing a model of trust advanced by Buechner and Tavani :39–51, 2011), I argue that the “short answer” to this question is yes. However, I also argue that a more complete and nuanced answer will require us to articulate the various levels of trust that are also possible in environments comprising both human agents and (...) AAs. In defending this view, I show how James Moor’s model for distinguishing four levels of ethical agents in the context of machine ethics :18–21, 2006) can help us to develop a framework that differentiates four levels of trust. Via a series of hypothetical scenarios, I illustrate each level of trust involved in HA–AA relationships. Finally, I argue that these levels of trust reflect three key factors or variables: the level of autonomy of the individual AAs involved, the degree of risk/vulnerability on the part of the HAs who place their trust in the AAs, and the kind of interactions that occur between the HAs and AAs in the trust environments.

In his poems, Paul Celan does not use words such as territory, border, border crossing, and only very rarely the word space. I would like to reconstruct the traces of?Heimat? in Celan, and perhaps try to describe what Heimat might have meant for the young Paul Antschel. That is to say, I would like to understand whether?Heimat? is synonymous with what Celan speaks about, many years after his name change, in the address given on the occasion of the Georg-Buechner-Preis:?Ich (...) suche auch, denn ich bin ja wieder da, wo ich begonnen habe, den Ort meiner eigenen Herkunft.? In the poems written at the time when Antschel is learning Hebrew as well as reading Martin Buber for the first time, I look for some basic figures Celan ties to his life in Bukovina at the time, in the environment of Czernowitzer Judentums. Aside from the works by Israel Chalfen, Else Keren and Elke Guenzel, I would like to make use of a book published some ten years ago, a detailed listing of Celan?s Paris library. I would like to consult this archive in the coming period, since Celan punctuated the margins of many of those books with evocations of his early creative period. (shrink)

We will all have sometimes cried out, while running between the bedroom and the bathroom, in the morning, as did King Peter of Georg Buechner’s Leonce und Lena: “But where is my shirt? and my trousers? Halt, few! Free will is here all open in front of me. Where are morals? Where are my cuffs? The categories are in the most scandalous confusion : two more buttons are sewn on, the snuff-box is stuck in the right pocket; my whole (...) system is in disarray.”. (shrink)
