Partial belief and flat-out belief

About the book: The idea that belief comes in degrees is based on the observation that we are more certain of some things than of others. Various theories try to give accounts of how measures of this confidence do or ought to behave, both as far as the internal mental consistency of the agent as well as his betting, or other, behaviour is concerned. This anthology is the first book to give a balanced overview of these theories. It also explicitly relates these debates to more traditional concerns of the philosophy of language and mind, and epistemic logic, namely how belief simpliciter does or ought to behave. The paradigmatic theory, probabilism (which holds that degrees of belief ought to satisfy the axioms of probability theory) is given most attention, but competing theories, such as Dempster-Shafer theory, possibility theory, and AGM belief revision theory are also considered. Each of these approaches is represented by one of its major proponents. The papers are specifically written to target advanced undergraduate students with a background in formal methods and beginning graduate students, but they will also serve as first point of reference for academics new to the area

A matter of opinion

This paper sets out the case for a two-level theory of human psychology. It takes its start from Daniel Dennett's distinction between belief and opinion, arguing that it has the power to account for a number of tensions within our commonsense concept of belief. It argues, however, that Dennett's account is seriously inadequate, particularly in its treatment of the role of opinion in practical reasoning. The paper goes on to sketch an alternative proposal which retains the virtues of Dennett's suggestion, while providing a richer and more satisfying account of the cognitive role of opinion

The anti-zombie argument

The zombie argument has come to occupy a central role in the case for a non-physicalist view of consciousness. This paper seeks to turn the tables on defenders of the argument ('zombists') by showing that a parallel argument can be run for physicalism. The argument invokes what I call anti-zombies – purely physical creatures that are nonetheless conscious. I show that, using the same resources as those employed by zombists, it is possible to construct an argument from the conceivability of anti-zombies to the truth of physicalism. l go on to defend the claim that anti-zombies are conceivable and to argue that the anti-zombie argument can be defeated only at the cost of rendering the zombie argument itself redundant. The moral of the paper is that dualists should not be zombists

Language, consciousness, and cross-modular thought

Carruthers suggests that natural language, in the form of inner speech, may be the vehicle of conscious propositional thought, but he argues that its fundamental cognitive role is as the medium of cross-modular thinking, both conscious and nonconscious. I argue that there is no evidence for nonconscious cross-modular thinking and that the most plausible view is that cross-modular thinking, like conscious propositional thinking, occurs only in inner speech

How we know our conscious minds: Introspective access to conscious thoughts

Carruthers considers and rejects a mixed position according to which we have interpretative access to unconscious thoughts, but introspective access to conscious ones. I argue that this is too hasty. Given a two-level view of the mind, we can, and should, accept the mixed position, and we can do so without positing additional introspective mechanisms beyond those Carruthers already recognizes

The rationale of rationalization

Fiery Cushman argues that “[r]ationalization is designed not to accurately infer unconscious mental states, but to construct new ones; it is not a discovery, but a fiction”. While we agree in broad strokes with the characterization of rationalization as a ‘useful fiction’, we think that Cushman’s claim remains ambiguous in two crucial respects: (i) the reality of beliefs and desires, i.e. the fictional status of folk psychological entities, and (ii) the degree to which they should be understood as useful and representative. Our aim here is to clarify both points and illuminate how rationalization could be understood as a useful fiction. In doing so, we aim to explicate the Rationale of Rationalization

Morally Respectful Listening and its Epistemic Consequences

What does it mean to listen to someone respectfully, that is, insofar as they are due recognition respect? This paper addresses that question and gives the following answer: it is to listen in such a way that you are open to being surprised. A specific interpretation of this openness to surprise is then defended

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
