As the end of the Millennium approaches, conspiracy theories are increasing in number and popularity. In this short essay, I offer an analysis of conspiracy theories inspired by Hume's discussion of miracles. My first conclusion is that whereas Hume can argue that miracles are, by definition, explanations we are not warranted in believing, there is nothing analytic that will allow us to distinguish good from bad conspiracy theories. There is no a priori method for distinguishing warranted conspiracy theories (say, those (...) explaining Watergate) from those which are unwarranted (say, theories about extraterrestrials abducting humans). Nonetheless, there is a cluster of characteristics often shared by unwarranted conspiracy theories. An analysis of the alleged explanatory virtues of unwarranted conspiracies suggests some reasons for their current popularity, while at the same time providing grounds for their rejection. Finally, I discuss how conspiracy theories embody an anachronistic world-view that places the contemporary zeitgeist in a clearer light. (shrink)

How ought we differentiate the senses? What, say, distinguishes vision from audition? The question comes in two versions. First, there is the traditional problem of individuating the senses in humans. Second, there is also an important question about what sensory modalities we ought to attribute to non-human animals, a version of the question that has been virtually ignored by philosophers. Modality ought to be construed as an “avenue into” an organism for information external to the central nervous system. Six proposed (...) criteria found in the philosophical literature concerning the senses are reviewed. Initially, four criteria—physics, neurobiology, behavior, and evolutionary or developmental dedication—are shown to be individually necessary and jointly sufficient. Next, two criteria—Aristotle's proper objects of sensation criterion and Grice's sensation or qualia criterion—are considered and rejected. One overarching goal here is to show that there is interesting contemporary work left to be done on this ancient philosophical question. (shrink)

One issue within conspiracy theory theory is whether, or to what extent, our central concept – – should map on to the common, lay sense of the term. Some conspiracy theory theorists insist that we use the term as everyday people use it. So, for example, if the term has a pejorative connotation in everyday parlance, then academic work on the concept should reflect that. Other conspiracy theory theorists take a more revisionist approach, arguing instead that while their use of (...) the theoretical concept should bear some relation to its use in natural language, it need not follow it subserviently. I argue that elements of this debate mirror related debates that were prominent in the philosophy of mind in the 1980s over folk psychology and eliminative materialism (debates that continue today, such as within the philosophy of perception and theories over how to individuate the senses). Then, there was a debate over whether the concepts of commonsense psychology, such as or, should be treated as theoretical posits, and hence open to significant revision or elimination, or whether they were instead the targets of explanation. I will argue that an eliminativist approach to has significant merit. (shrink)

After first noting that I seek to broaden the definition of science fiction to a little more loosely defined speculative fiction, this essay explores four different ways in which fiction can work together with both the sciences and the philosophy of perception. This cooperation is needed because there is much about the sensory worlds of humans and non-human animals of which we continue to be ignorant. First, speculative fiction can be a source of hypotheses about the nature of the senses. (...) Second, it can help us understand the inner worlds of beings different from us. Third, speculative fiction often pushes us to investigate the ethical and social dimensions of sensory difference. Finally, speculative fiction can play an important role in reconciling our scientific understanding of the senses with a more commonsense understanding of same. (shrink)

An overview of the current epistemic literature concerning conspiracy theories, as well as indications for future research avenues on the topic.

Traditional secular conspiracy theories and explanations of worldly events in terms of supernatural agency share interesting epistemic features. This paper explores what can be called “supernatural conspiracy theories”, by considering such supernatural explanations through the lens of recent work on the epistemology of secular conspiracy theories. After considering the similarities and the differences between the two types of theories, the prospects for agnosticism both with respect to secular conspiracy theories and the existence of God are then considered. Arguments regarding secular (...) conspiracy theories suggest ways to defend agnosticism with respect to God from arguments that agnosticism is not a logically stable position and that it ultimately collapses into atheism, as has been argued by N. Russell Hanson and others. I conclude that such attacks on religious agnosticism fail to appreciate the conspiratorial features of God's alleged role in the universe. (shrink)

The charge that anthropomorphizing nonhuman animals is a fallacy is itself largely misguided and mythic. Anthropomorphism in the study of animal behavior is placed in its original, theological context. Having set the historical stage, I then discuss its relationship to a number of other, related issues: the role of anecdotal evidence, the taxonomy of related anthropomorphic claims, its relationship to the attribution of psychological states in general, and the nature of the charge of anthropomorphism as a categorical claim. I then (...) argue that the categorical reading of anthropomorphism cannot work and that it misrepresents what is being claimed when one claims that traits are shared between humans and nonhumans. We should think of such claims not as anthropomorphic per se– because that implies the trait is intrinsically human and only derivatively nonhuman. Instead, traits shared with mammals are mammalomorphic, for example, or primatomorphic when shared by primates. (shrink)

This paper explores the relationship between psychology and neurobiology in the context of cognitive science. Are the sciences that constitute cognitive science independent and theoretically autonomous, or is there a necessary interaction between them? I explore Fodor's Multiple Realization Thesis (MRT) which starts with the fact of multiple realization and purports to derive the theoretical autonomy of special sciences (such as psychology) from structural sciences (such as neurobiology). After laying out the MRT, it is shown that, on closer inspection, the (...) argument is either circular or self-undermining--the argument either assumes the very autonomy it seeks to demonstrate or the concluded autonomy is contradicted by the theoretical interdependence invoked by the premises of the argument. Next, I explore a concrete example of multiple realization in the explanation of animal behavior: the convergent evolution of jamming avoidance behaviors in three genera of weakly electric fish. Contrary to the image painted by the MRT, the work on these animals involves a high degree of interaction between the various levels of investigation. The fact that our understanding of electric fish behavior involves functional theories and multiple realization without the kind of disunified science that is supposed to follow from such a situation indicates that the mere fact of multiple realization cannot be the basis for an autonomous psychology.

Largely a response to Lee Basham’s essay “Malevolent Global Conspiracy.” After presenting an update on the status of conspiracy theories surrounding the 1995 Oklahoma City bombing, I agree with Basham that falsification and paranoia are not effective ways to criticize conspiratorial thinking. However, I am not convinced with the case Basham presents against worries that conspiracy theories often falter by overestimating the ability of large, public institutions to be secretly and effectively controlled. His appeal to the historical record can be (...) read as suggesting that malevolent global action can be effectively carried out in full public view, obviating recourse to conspiracy. (shrink)

Naturalism concerning the mental is the belief that the tools and concepts of natural science are necessary to achieve an understanding of the mind. After briefly setting the stage of naturalism and the mind, I pose the question of naturalism about the mind in its historical context, comparing the development of naturalist approaches to philosophy of mind to Russell's “hiving off” model of the history of Western philosophy, in which parts of philosophy have split away from the field as we (...) have developed new ways to answer questions once central to philosophy. Next, after distinguishing ontological from methodological senses of naturalism, I explore a number of different 20th‐century naturalist approaches to studying the mind, ending with a discussion of eliminative materialism and its stress on the continuity of scientific (naturalist) and commonsense understandings of the mind.

Neuroethology is a branch of biology that studies the neural basis of naturally occurring animal behavior. This science, particularly a recent program called computational neuroethology, has a similar structure to the interdisciplinary endeavor of cognitive science. I argue that it would be fruitful to conceive of cognitive science as the computational neuroethology of humans. However, there are important differences between the two sciences, including the fact that neuroethology is much more comparative in its perspective. Neuroethology is a biological science and (...) as such, evolution is a central notion. Its target organisms are studied in the context of their evolutionary history. The central goal of this paper is to argue that cognitive science can and ought to be more comparative in its approach to cognitive phenomena in humans. I show how the domain of cognitive phenomena can be divided up into four different classes, individuated by the relative phylogenetic uniqueness of the behavior. I then describe how comparative evidence can enrich our understanding in each of these different arenas. (shrink)

This collection offers an introduction to Churchland's work, as well as a critique of some of his most famous philosophical positions.

Artificial life (ALife) is the attempt to create artificial instances of life in a variety of media, but primarily within the digital computer. As such, the field brings together computationally-minded biologists and biologically-minded computer scientists. I argue that this new field is filled with interesting philosophical issues. However, there is a dearth of philosophers actively conducting research in this area. I discuss two books on the new field: Margaret A. Boden's The philosophy of artificial life and Christopher G. Langton's Artificial (...) life: an overview. They cover three areas of philosophical interest: the definition of life, the relationship between life and mind, and the possibility of creating life within a computational environment. This discussion allows me to critique past work in the philosophy of ALife that tends to see the field as a proving ground for traditional arguments from the philosophy of artificial intelligence. Instead, I suggest, what is interesting about ALife is how it differs from artificial intelligence and that the most interesting philosophical issues in the area are those derived from biology, not psychology. I recommend that these two books taken together constitute an interesting introduction to ALife and the wealth of philosophical issues found therein. (shrink)

This paper is a complement to the recent wealth of literature suggesting a strong philosophical relationship between artificial life (A-Life) and artificial intelligence (AI). I seek to point out where this analogy seems to break down, or where it would lead us to draw incorrect conclusions about the philosophical situation of A-Life. First, I sketch a thought experiment (based on the work of Tom Ray) that suggests how a certain subset of A-Life experiments should be evaluated. In doing so, I (...) suggest that treating A-Life experiments as if they were just AI experiments applied to a new domain may lead us to see problems (like Searle’s “Chinese room”) which do not exist. In the second half of the paper, I examine the reasons for suggesting that there is a philosophical relationship between the two fields. I characterize the strong thesis for a translation of AI concepts, metaphors, and arguments into A-Life as the “global replacement strategy.” Such a strategy is only fruitful inasmuch as there is a strong analogy between AI and A-Life. I conclude the paper with a discussion of two areas where such a strong analogy seems to break down. These areas relate to eliminative materialism and the lack of a “subjective” element in biology. I conclude that the burden of proof lies with the person who wishes to import a concept from another discipline into A-Life, even if that other discipline is AI. (shrink)

In Western common sense, one speaks of there being five human senses, a claim apparently challenged by the biological and psychological sciences. Part of this challenge comes in the form of claiming the existence of additional senses. Part of the challenge comes from positing multiple senses where common sense only speaks of one, such as with the fractionation of “touch” into pressure and temperature senses. One conceptual difficulty in thinking about the number and division of senses is that it's not (...) clear whether the different senses constitute natural kinds and, if not, what kind of kind they are. Should we favor antirealism with respect to the senses, akin to the arguments of some concerning the nature of species or race? I will argue that this first problem is compounded by another: that we ought to be pluralists with respect to the senses—what is meant by the term “sense” varies from context to context, varying even between scientific contexts.

There are two ways to do the unexpected. The banal way—let's call it the expectedly unexpected—is simply to chart the waters of what is and is not done, and then set out to do something different. For a philosopher, this can be done by embracing a method of non sequitor or by perhaps inverting some strongly held assumption of the field. The more interesting way— the unexpectedly unexpected—is to transform the expectations themselves; to do something new and contextualize it in (...) such a way that it not only makes perfect sense, but has the audience scratching their heads and saying, “Of course!” To do the unexpectedly unexpected on a regular basis is the true mark of genius. It recalls Kant's characterization of the genius as the one who not merely follows or breaks the rules of art but that, “Genius is the natural endowment that gives the rule to art.” We would not like to make the bold claim that Paul M. Churchland (PMC) is a philosophical genius of Kantian standards, but he sometimes achieves the unexpectedly unexpected and his position on the issue of scientific realism is a fine example of this. Given other views he holds and the philosophical forebears he holds dear, one might expect him to embrace an antirealism with respect to the posits of scientific theories. But, quite to the contrary, Churchland is one of the strongest contemporary philosophical voices on behalf of scientific realism. And, as we will discuss in this chapter, a closer look at this reasoning reveals that his realism is not perverse, it is exactly the sort of position he should be expected to hold, if only we understand the philosophical issues correctly.

Compiled by an archaeologist and philosopher of science, Science at the Frontiers: Perspectives on the History and Philosophy of Science supplements current literature in the history and philosophy of science with essays approaching the traditional problems of the field from new perspectives and highlighting disciplines usually overlooked by the canon. William H. Krieger brings together scientists from a number of disciplines to answer these questions and more in a volume appropriate for both students and academics in the field.

Are attributions of content and function determinate, or is there no fact of the matter to be fixed? Daniel Dennett has argued in favor of indeterminacy and concludes that, in practice, content and function cannot be fixed. The discovery of an electrical modality in vertebrates offers one concrete instance where attributions of function and content are supported by a strong scientific consensus. A century ago, electroreception was unimagined, whereas today it is widely believed that many species of bony fish, amphibians, (...) sharks, skates, and rays possess this non-human sensory modality. A look at the history of science related to this discovery reveals a highly interdisciplinary endeavor, encompassing ethology, behavioral analysis, neuroscience, and evolutionary biology. While each area provides important evidence, none is sufficient on its own to fix content and function. Instead, I argue that an interdisciplinary, neuroethological approach is required to carry out such determinations. Further, a detailed consideration of biological research suggests that while content and function claims are empirically underdetermined and uncertain, there is insufficient reason to believe in an additional problem of indeterminism. In particular, Dennett's indeterminism arises from a research methodology -- logical adaptationism -- that generates evidence from only one of the areas of neuroethology. However, logical adaptationism does not reflect adaptationism as it is practiced in contemporary biology. I conclude that Dennett is faced with a dilemma: On the one hand, he can hold to logical adaptationism and the indeterminism that results from it, while giving up the relevance of his arguments to biological practice. On the other, he can embrace a more accurate version of adaptationism -- one which plays a role in a larger neuroethological framework -- but from which no strong indeterminacy claims follow. (shrink)
