We naturally evaluate the beliefs of others, sometimes by deliberate calculation, and sometimes in a more immediate fashion. Epistemic intuitions are immediate assessments arising when someone’s condition appears to fall on one side or the other of some significant divide in epistemology. After giving a rough sketch of several major features of epistemic intuitions, this article reviews the history of the current philosophical debate about them and describes the major positions in that debate. Linguists and psychologists also study epistemic assessments; the last section of the paper discusses some of their research and its potential relevance to epistemology.

Contemporary analyses of biological function almost invariably advocate a naturalistic analysis, grounding biological functions in some feature of the mind-independent world. Many recent accounts suggest that no single analysis will be appropriate for all cases of use and that biological teleology should be split into several distinct categories. This paper argues that such accounts have paid too little attention to the way in which functional language is used, concentrating instead on the types of situation in which it is used. An example of the role of teleology in science is examined and, on the basis of conclusions drawn from this, an alternative unifying analysis is proposed. It is suggested that, contrary to naturalistic accounts, teleology in biology carries no ontological commitment whatsoever to any class of mind-independent entities or properties. Instead, it is best regarded as a methodological device which is used to focus interest, formulate research perspectives and facilitate the structuring of certain questions or types of question that are pertinent in a given context of interest.

In this paper I pursue a possibility that some versions of arguments addressed against the libertarian notion of self-ownership have some definitive implications regarding the equalisandum debate carried out by egalitarians. I have in mind specifically the kind of approach that challenges self-ownership as a morally fundamental value through some inventive counterexamples. So, while I shall argue that the negative arguments against self-ownership are conclusive, my primary attempt is to demonstrate that such arguments can be employed to say something interesting about the equalisandum debate itself; namely, that resources cannot function as the desirable equalisandum, and that there are some reasons for preferring capabilities over welfare as the desired currency for egalitarianism.

In this paper, I examine metaphysical aspects in the neuroeconomics debate. I propose that part of the debate can be better understood by supposing two metaphysical stances, mechanistic and functional. I characterize the two stances, and discuss their relations. I consider two models of framing, in order to illustrate how the features of mechanistic and functional stances figure in the practice of the sciences of individual decision making.

Recently something close to a consensus about the best way to naturalize the notion of biological function appears to be emerging. Nonetheless, teleological notions in biology remain controversial. In this paper we provide a naturalistic analysis for the notion of natural design. Many authors assume that natural design should be assimilated directly to function. Others find the notion problematic because it suggests that evolution is a directed process. We argue that both of these views are mistaken. Our naturalistic account does not simply equate design with function. We argue that the distinction between function and design is important for understanding the evolution of the physical and behavioral traits of organisms.

I argue that there are at least four different ways in which the term 'function' is used in connection with the study of living organisms, namely: (1) function as (mere) activity, (2) function as biological role, (3) function as biological advantage, and (4) function as selected effect. Notion (1) refers to what an item does by itself; (2) refers to the contribution of an item or activity to a complex activity or capacity of an organism; (3) refers to the value for the organism of an item having a certain character rather than another; (4) refers to the way in which a trait acquired and has maintained its current share in the population. The recognition of a separate notion of function as biological advantage solves the problem of the indeterminate reference situation that has been raised against a counterfactual analysis of function, and emphasizes the importance of counterfactual comparison in the explanatory practice of organismal biology. This reveals a neglected problem in the philosophy of biology, namely that of accounting for the insights provided by counterfactual comparison.

Much of the debate surrounding the concept of information in biology centers on the question of whether or not biological systems ‘really’ carry information. The criterion for determining if a system “really” carries information is whether or not there is a principled, theoretical account of information that captures the relevant biological usages. If biological systems do not carry information in this sense, information talk is termed merely heuristic and dismissed as philosophically uninteresting. To date, all three proposed theoretical accounts of information—mathematical, causal and teleosemantic—fail to capture the meaning of biologists. Details of other biological practices that utilize informational concepts are often lost because the debate is too focused on one instance of information talk—genetic information and because biological representations are thought to need a certain kind of theoretical foundation. The problem with this methodology is that it takes the failure of philosophical accounts of information to capture current biological practices as conclusive evidence that informational representations in biology are incoherent. This approach is backwards. A better strategy is to get a clear understanding of biological practice and then to use it to shape our understanding of the philosophical significance of biological information. In this paper, I shift attention from abstract reasoning about information in the philosophical literature to concrete reasoning about informational models in biology. The current debate pays too little attention to the biologically prominent concept of signal. I develop a contextualized understanding of signaling models in biological practice. I argue that biologists use the concept of signal to model distinct functional roles in biological systems and not in any of the theoretical senses of information found in the current philosophical literature. For cell biologists, a signal causally indicates the state of a system at a given point and is used in the context of a style of functional explanation generally known as ‘causal role function,’ in which a mechanism or entity has a function if its behavior explains a contribution to a capacity of interest. I support this analysis with an example drawn from cell biology and reframe the debate over the significance of informational terms in biology. The focus on signal recasts the debate by highlighting examples of information talk which are central to active research programs in biology. The advantage of looking at these models is that their centrality to biological practice forces us to reconsider the adequacy of a methodology that dismisses biological models because we lack a particular kind of philosophical understanding of them. Standard philosophical accounts of information rely on assumptions appropriate for the needs of philosophers but are ill-suited for capturing biological practice. A contextualized understanding of the role of signal in biological p

Many philosophers believe that 1) most uses of functional language in biology make implicit reference to natural selection and 2) the fundamental way in which biologists identify parts and processes in organisms is by their selected function(s). Both these claims are mistaken. Much functional language in biology refers to actual causal roles, and if this were not so, biology would be impossible. The extensive biological literature on the ‘character concept’ focuses on another principle of biological identity, namely homology. I outline some of this work and use it to refute philosophical arguments for the importance and ubiquity of classification by adaptive function.

According to historical theories of biological function, a trait's function is determined by natural selection in the past. I argue that, in addition to historical functions, ahistorical functions ought to be recognized. I propose a theory of biological function which accommodates both. The function of a trait is the way it contributes to fitness and fitness can only be determined relative to a selective regime. Therefore, the function of a trait can only be specified relative to a selective regime. Apart from its desirable pluralism, only this view of relational function can support the function/accident and function/malfunction distinctions commonly thought to be part of the concept of function. Furthermore, only relational function correctly characterizes the explanatory consequences of function attributions in evolutionary biology.
