In the tradition of Milton Friedman's 1962 classic, Capitalism and Freedom, Lansing Pollock draws on moral, political, and economic theory to defend a libertarian vision of the good society. Pollock argues that mutual consent, derived from a fundamental Kantian moral equality, is the ideal standard for judging relations between persons. He contends that if the equal right of all persons to be free is taken seriously, most of the coercion by government that many take for granted is (...) immoral. Pollock situates libertarian moral theory in an American historical context, one compatible with the views of James Madison and Thomas Jefferson. Pollock argues that when the Constitution is interpreted according to the political philosophy of the framers, the modern welfare state is unconstitutional. Pollock goes on to demonstrate how free market economies promote human well-being, whereas government regulation is often counterproductive. In advocating a reduction in the size and scope of government, Pollock includes applied policy analyses of poverty and health care, among other topical issues. He also offers an innovative solution to the problem of funding a limited government without violating individual rights. The strength of The Free Society lies in its synthetic achievement. In a book that is accessibly written and sure to appeal to scholar and lay reader alike, Pollock provides a compelling conception of the good society--one in which the libertarian vision includes moral, social, political, and economic perspectives.

Corporate violations of the law are occurring with increasing frequency and with increasing public attention. Solutions to date have proved ineffectual because of the problem of determining whom is to be punished for the offense of the corporation. Instead of individual jail terms or corporate fines, we propose that the dissolution of the corporation be considered as a more effectual means of conforming corporate behavior to the norms of the legal system.

Pollock describes an exciting theory of rationality and its partial implementation in OSCAR, a computer system whose descendants will literally be persons.

In December 2010, the governor of Mississippi suspended the dual life sentences of two African American sisters who had been imprisoned for sixteen years on an extraordinary condition: that Gladys Scott donate a kidney to her ailing sister Jamie Scott. The Scott Sisters’ case is a highly unusual one, yet it is a revealing site for inquiry into US biopolitics more broadly. Close attention to the conditional release and its context demands a broader frame than traditional bioethics and helps to (...) push science and technology studies analysis of race past its conventional focus on genetics. This article draws on the Scott Sisters’ case as a site for interrogating the US context of racialized mass incarceration and kin-oriented and consumerist valorization of organ donation. Tensions between racialized exclusions, the promise of consumerist freedom, and the lack of expectations of the state are foundational to a distinctly American biological citizenship. By putting the Scott Sisters’ case into conversation with broader arguments about incarceration as a site of racialization and STS literatures of organ transplantation and of biological citizenship in diverse geographical sites, this article seeks to articulate some of the racialized contours of biopolitics in the United States.

David Hume: Moral Philosophy Although David Hume is commonly known for his philosophical skepticism, and empiricist theory of knowledge, he also made many important contributions to moral philosophy. Hume’s ethical thought grapples with questions about the relationship between morality and reason, the role of human emotion in thought and action, the nature of moral … Continue reading David Hume: Moral Philosophy →.

Pollock argues that theories of ideal rationality are largely irrelevant to the decision making of real agents. Thinking about Acting aims to provide a theory of "real rationality.".

Franz Rosenzweig's near-conversion to Christianity in the summer of 1913 and his subsequent decision three months later to recommit himself to Judaism is one of the foundational narratives of modern Jewish thought. In this new account of events, Benjamin Pollock suggests that what lay at the heart of Rosenzweig's religious crisis was not a struggle between faith and reason, but skepticism about the world and hope for personal salvation. A close examination of this important time in Rosenzweig's life, the (...) book also sheds light on the full trajectory of his philosophical development. (shrink)

In this major book, Griselda Pollock engages boldly in the culture wars over `what is the canon?` and `what difference can feminism make?` Do we simply reject the all-male line-up and satisfy our need for ideal egos with an all women litany of artistic heroines? Or is the question a chance to resist the phallocentric binary and allow the ambiguities and complexities of desire - subjectivity and sexuality - to shape the readings of art that constantly displace the present (...) gender demarcations?

The “grand problem” of AI has always been to build artificial agents with human-like intelligence. That is the stuff of science fiction, but it is also the ultimate aspiration of AI. In retrospect, we can understand what a difficult problem this is, so since its inception AI has focused more on small manageable problems, with the hope that progress there will have useful implications for the grand problem. Now there is a resurgence of interest in tackling the grand problem head-on. (...) Perhaps AI has made enough progress on the little problems that we can fruitfully address the big problem. The objective is to build agents of human-level intelligence capable of operating in environments of real-world complexity. I will refer to these as GIAs — “generally intelligent agents”. OSCAR is a cognitive architecture for GIAs, implemented in LISP.1 OSCAR draws heavily on my work in philosophy concerning both epistemology (Pollock 1974, 1986, 1990, 1995, 1998, 2008b, 2008; Pollock and Cruz 1999; Pollock and Oved, 2005) and rational decision making (2005, 2006, 2006a).

Epistemology is about how we can know the various things we claim to know. Epistemology is driven by attempts to answer the question, “How do you know?” This gives rise to investigations on several different levels. At the lowest level, philosophers investigate particular kinds of knowledge claims. Thus we find theories of perceptual knowledge (“How do you know the things you claim to know directly on the basis of perception?”), theories of induction and abduction (“How do you know the general (...) truths you infer from observation of particular cases?”), theories of our knowledge of other minds, theories of mathematical knowledge, and so forth. At an intermediate level, topics are investigated that pertain to all or most of the specific kinds of knowledge discussed at the lowest level. Theories of reasoning, both deductive and defeasible, occur at this level. At the highest level we find general epistemological theories that attempt to explain how knowledge in general is possible. At this level we encounter versions of foundationalism, coherentism, probabilism, reliabilism, and direct realism. One can be doing epistemology by working at any of these levels. The levels cannot be isolated from each other, however. Work at any level tends to presuppose something about the other levels. For example, work on inductive reasoning at least presupposes that reasoning plays a role in the acquisition or justification of beliefs and normally presupposes something about the structure of defeasible reasoning.

Imagine yourself sitting on your front porch, sipping your morning coffee and admiring the scene before you. You see trees, houses, people, automobiles; you see a cat running across the road, and a bee buzzing among the flowers. You see that the flowers are yellow, and blowing in the wind. You see that the people are moving about, many of them on bicycles. You see that the houses are painted different colors, mostly earth tones, and most are one-story but a (...) few are two-story. It is a beautiful morning. Thus the world interfaces with your mind through your senses. There is a strong intuition that we are not disconnected from the world. We and the other things we see around us are part of a continuous whole, and we have direct access to them through vision, touch, etc. However, the philosophical tradition tries to drive a wedge between us and the world by insisting that the information we get from perception is the result of inference from indirect evidence that is about how things look and feel to us. The philosophical problem of perception is then to explain what justifies these inferences. We will focus on visual perception. Figure one presents a crude diagram of the cognitive system of an agent capable of forming beliefs on the basis of visual perception. Cognition begins with the stimulation of the rods and cones on the retina. From that physical input, some kind of visual processing produces an introspectible visual image. In response to the production of the visual image, the cognizer forms beliefs about his or her surroundings. Some beliefs the perceptual beliefs are formed as direct responses to the visual input, and other beliefs are inferred from the perceptual beliefs. The perceptual beliefs are, at the very least, caused or causally influenced by having the image. This is signified by the dashed arrow marked with a large question mark. We will refer to this as the mystery link. Figure one makes it apparent that in order to fully understand how knowledge is based on perception, we need three different theories.. (shrink)

An argument is self-defeating when it contains defeaters for some of its own defeasible lines. It is shown that the obvious rules for defeat among arguments do not handle self-defeating arguments correctly. It turns out that they constitute a pervasive phenomenon that threatens to cripple defeasible reasoning, leading to almost all defeasible reasoning being defeated by unexpected interactions with self-defeating arguments. This leads to some important changes in the general theory of defeasible reasoning.

This paper recognizes the complexity of the debate on informed consent and discusses the importance of the ongoing process of consent for people affected by Huntington's disease (HD). Although written information may not be the most appropriate form of obtaining informed consent in qualitative research, it remains an important part of the ethical approval process for health research in the UK. This paper draws on a study in which the information sheet and consent form were specifically designed to help obtain (...) consent from people who may be impaired by the cognitive and physical effects of HD. The forms were developed by drawing on expert opinion and relevant literature and fall in line with recommendations from the Mental Capacity Act 2005 to encourage people to make their own decisions. The paper describes the feasibility of a method for obtaining consent as an ongoing process with patients affected by HD using information sheets and consent forms specifically designed for people with potential cognitive and/or physical impairments. In conclusion, this paper adds a pragmatic approach to the debate on informed consent by describing the development of a written information sheet and consent form being used in a current social research study. Particular emphasis is placed on the importance of written information being adapted according to the needs of potential participants. (shrink)

A theory of rational choice is a theory of how an agent should, rationally, go about deciding what actions to perform at any given time. For example, I may want to decide whether to go to a movie this evening or stay home and read a book. The actions between which we want to choose are perfectly ordinary actions, and the presumption is that to make such a decision we should attend to the likely consequences of our decision. It is (...) assumed that these decisions must be made in the face of uncertainty regarding both the agent’s initial situation and the consequences of his actions. (shrink)

This new edition of the classic Contemporary Theories of Knowledge has been significantly updated to include analyses of the recent literature in epistemology.

The paper argues that Donnellan’s distinction between the referential and attributive uses of definite descriptions, whilst a genuine feature of language, does not count against Russell’s Theory of Descriptions where Russell’s theory is regarded as a theory of the semantics of descriptions and not the pragmatics of individual uses on a particular occasion. The argument I shall present is simple but decisive and ought to resolve once and for all the debate about the significance of Donnellan’s distinction for Russell’s theory, (...) provided of course that Russell’s theory really does concern the semantics of definite descriptions rather than their use on particular occasions.

One of the most striking characteristics of human beings is their ability to function successfully in complex environments about which they know very little. In light of our pervasive ignorance, we cannot get around in the world just reasoning deductively from our prior beliefs together with new perceptual input. As our conclusions are not guaranteed to be true, we must countenance the possibility that new information will lead us to change our minds, withdrawing previously adopted beliefs. In this sense, our (...) reasoning is “defeasible”. The question arises how defeasible reasoning works, or ought to work. In particular we need rules governing what a cognizer ought to believe given a set of interacting arguments some of which defeat others. That is what is called a “semantics” for defeasible reasoning, and this chapter will propose a new semantics that avoids certain clear counter-examples to all existing semantics. (shrink)

A large U.S. government investigation into arms procurement procedures with corporate contractors has recently led to guilty pleas to fraud and illegal use of classified documents. Operation Ill Wind has brought public attention to the criminal and unethical conduct of large defense contractors in their dealings with the government. This article will review how the defense contract bidding process operates and why illegal activity has been able to compromise the process. We will offer proposals to improve the process in light (...) of the present inquiry. (shrink)
