Anthropic reasoning is a form of statistical reasoning based upon finding oneself a member of a particular reference class of conscious beings. By considering empirical distribution functions defined over animal life on Earth, we can deduce that the vast bulk of animal life is unlikely to be conscious.

Many traditional attempts to show that nonhuman animals are deserving of moral consideration have taken the form of an argument by analogy. However, arguments of this kind have had notable weaknesses and, in particular, have not been able to convince two kinds of skeptics. One of the most important weaknesses of these arguments is that they fail to provide theoretical justifications for why particular physiological similarities should be considered relevant. This paper examines recent empirical research on pain and, in particular, (...) explores the implications of the dissociation between the sensory and the affective pain pathways. It is argued that these results show that the belief that nonhuman animals experience pain in a morally relevant way is reasonable, though not certain. It is further argued that the proposal to explore the relationship between consciousness and various forms of learning challenges the aforementioned skeptics to provide more physiological details for their claims that nonhuman mammals are probably not conscious.

Peter Carruthers argues that phenomenal consciousness might not matter very much either for the purpose of determining which nonhuman animals are appropriate objects of moral sympathy, or for the purpose of explaining for the similarities in behavior of humans and nonhumans. Carruthers bases these claims on his version of a dispositionalist higher-order thought (DHOT) theory of consciousness which allows that much of human behavior is the result of first-order beliefs that need not be conscious, and that prima facie judgments about (...) the importance of consciousness are due to confabulation. We argue briefly against his claim that 'the moral landscape can remain unchanged' even if all or nearly all nonhuman animals are taken to be incapable of conscious experience. We then show how a first-order representational (FOR) theory of consciousness might be defended against Carruthers' criticisms. Finally, we argue that Carruthers' appeal to confabulation undercuts his own arguments for an evolutionary explanation for consciousness, posing a greater epiphenomenalist threat to his DHOT theory than he concedes.

According to F. Adams [this journal, vol. 68, 2018] cognition cannot be realized in plants or bacteria. In his view, plants and bacteria respond to the here-and-now in a hardwired, inflexible manner, and are therefore incapable of cognitive activity. This article takes issue with the pursuit of plant cognition from the perspective of an empirically informed philosophy of plant neurobiology. As we argue, empirical evidence shows, contra Adams, that plant behavior is in many ways analogous to animal behavior. This renders (...) plants suitable to be described as cognitive agents in a non-metaphorical way. Sections two to four review the arguments offered by Adams in light of scientific evidence on plant adaptive behavior, decision-making, anticipation, as well as learning and memory. Section five introduces the ‘phyto-nervous’ system of plants. To conclude, section six resituates the quest for plant cognition into a broader approach in cognitive science, as represented by enactive and ecological schools of thought. Overall, we aim to motivate the idea that plants may be considered genuine cognitive agents. Our hope is to help propel public awareness and discussion of plant intelligence once appropriately stripped of anthropocentric preconceptions of the sort that Adams' position appears to exemplify.

This paper aims to uncover where the disagreement between illusionism and anti-illusionism about phenomenal consciousness lies fundamentally. While illusionists claim that phenomenal consciousness does not exist, many philosophers of mind regard illusionism as ridiculous, stating that the existence of phenomenal consciousness cannot be reasonably doubted. The question is, why does such a radical disagreement occur? To address this question, I list various characterisations of the term “phenomenal consciousness”: (1) the what-it-is-like locution, (2) inner ostension, (3) thought experiments such as philosophical (...) zombies, inverted qualia and Mary’s room, (4) scientific knowledge about secondary properties, (5) theoretical properties such as being ineffable and being intrinsic, and (6) appearance/reality collapse. Then I examine whether each characterization provides (i) a dubitable sense of phenomenal consciousness in which the existence of phenomenal consciousness can be reasonably doubted, (ii) an indubitable sense in which its existence cannot be reasonably doubted, or (iii) a gray sense in which it is controversial whether its existence can be reasonably doubted. By doing so, I show that there is no single sense of phenomenal consciousness in which illusionists and anti-illusionists disagree whether the existence of phenomenal consciousness can be reasonably doubted. I conclude that the disagreement between illusionists and anti-illusionists is fundamentally terminological: while illusionists adopt a dubitable sense of phenomenal consciousness, anti-illusionists adopt an indubitable sense of phenomenal consciousness. Because of the extreme vagueness and ambiguity of the term “phenomenal consciousness”, illusionists and anti-illusionists fail to see that they talk about different senses of phenomenal consciousness.

There is considerable debate in comparative psychology and philosophy over whether nonhuman animals can attribute beliefs. The empirical studies that suggest that they can are shown to be inconclusive, and the main philosophical and empirical arguments that purport to show they cannot are shown to be invalid or weak. What is needed to move the debate and the field forward, it is argued, is a fundamentally new experimental protocol for testing belief attribution in animals, one capable of distinguishing genuine belief-attributing (...) subjects from their perceptual-state attributing and behavior-reading counterparts. Such a protocol is outlined and defended. The rest, it is argued, is in the hands of experimentalists. (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.

The view (held, e.g., by Davidson) that the having of beliefs and desires presupposes the having of reflective capacities is sometimes supported by appealing to the idea that the concept of belief is a concept of a mental state which involves a normative aspect: beliefs can be “successful” or “unsuccessful” from the perspective of their possessors, and sometimes discarded in light of their “failure.” This naturally invites the idea that believers must be capable of reflecting on their beliefs. Desires presuppose (...) reflectivity if only in virtue of their essential linkage with beliefs. This paper suggests a sense in which mental states—including those of non-reflective creatures—can have such a normative aspect. On this suggestion, the intelligible relations that obtain between cognitive states and conative states open the door for the possibility of normativity without reflectivity. Due to these relations, a creature's beliefs can be successful or unsuccessful from its own perspective even without its conceiving of them. (shrink)

Ambitious higher-order theories of consciousness aim to account for conscious states when these are understood in terms of what-it-is-like-ness. This paper considers two arguments concerning this aim, and concludes that ambitious theories fail. The misrepresentation argument against HO theories aims to show that the possibility of radical misrepresentation—there being a HO state about a state the subject is not in—leads to a contradiction. In contrast, the awareness argument aims to bolster HO theories by showing that subjects are aware of all (...) their conscious states. Both arguments hinge on how we understand two related notions which are ubiquitous in discussions of consciousness: those of what-it-is-like-ness and there being something it is like for a subject to be in a mental state. This paper examines how HO theorists must understand the two crucial notions if they are to reject the misrepresentation argument but assert the awareness argument. It shows that HO theorists can and do adopt an understanding—the HO reading—which seems to give them what they want. But adopting the HO reading changes the two arguments. On this reading, the awareness argument tells us nothing about those states there is something it is like to be in, and so offers no support to ambitious HO theories. And to respond to the misrepresentation understood according to the HO reading is to simply ignore the argument presented, and so to give no response at all. As things stand, we should deny that HO theories can account for what-it-is-like-ness. (shrink)

In general, epistemic emotions can be characterized as emotions that concern the subject's own states and mental processes and are associated with cognition and knowledge acquisition. They are the result of a cognitive inconsistency that may appear as a consequence of unexpected information that contradicts previous knowledge. They have a significant impact on the exploration and generation of knowledge about oneself and the world, as well as on conceptual changes and cognitive efficiency. There is no interspecies comparative perspective in experimental (...) studies on epistemic emotions. At first glance, this situation is not controversial, because the category of epistemic emotions has been defined in such a way that it seems to belong only to people. Inconsistencies arise when comparative research in the field of cognitive ethology, primatology or comparative psychology is analyzed. Researchers point to a number of behaviors of nonhuman animals that prove that they have a wide range of emotions - including those that stand out in the catalog of epistemic emotions, i.e. surprise, curiosity or uncertainty. The presented article is an attempt to answer the questions posed in the title and an introduction to research on an adequate model of epistemic emotions, taking into account the results of research in the above-mentioned areas.

In a couple of short papers, Donald Davidson holds that a creature cannot think unless it is the interpreter of the speech of another. At first blush, speaking a language is, therefore, a necessary condition for thought. His controversial claims has led many to regard him as a follower of the Cartesian tradition wherein languageless creatures are nothing but mindless machines. Against this widely shared interpretation, in this paper we put forward a more charitable interpretation of Davidson’s claims. According to (...) our reading, Davidson never meant to argue that languageless creatures do not think. Instead, the only thing his arguments purport to show is that one will never be in a position to confirm that they do. This paper consists of a defense of the idea that Davidson is better seen as endorsing radical skepticism as to whether languageless creatures think. (shrink)

According to higher-order thought accounts of phenomenal consciousness it is unlikely that many non-human animals undergo phenomenally conscious experiences. Many people believe that this result would have deep and far-reaching consequences. More specifically, they believe that the absence of phenomenal consciousness from the rest of the animal kingdom must mark a radical and theoretically significant divide between ourselves and other animals, with important implications for comparative psychology. I shall argue that this belief is mistaken. Since phenomenal consciousness might be almost (...) epiphenomenal in its functioning within human cognition, its absence in animals may signify only relatively trivial differences in cognitive architecture. Our temptation to think otherwise arises partly as a side-effect of imaginative identification with animal experiences, and partly from mistaken beliefs concerning the aspects of common-sense psychology that carry the main explanatory burden, whether applied to humans or to non-human animals.

This paper argues that it is possible for suffering to occur in the absence of phenomenal consciousness – in the absence of a certain sort of experiential subjectivity, that is. (Phenomenal consciousness is the property that some mental states possess, when it is like something to undergo them, or when they have subjective feels, or possess qualia.) So even if theories of phenomenal consciousness that would withhold such consciousness from most species of non-human animal are correct, this neednt mean that (...) those animals dont suffer, and arent appropriate objects of sympathy and concern.

It is highly consensual that we can perceive so-called low-level properties such as shape, color, motion, spatial location, and illumination through vision. But it’s more controversial whether the contents of visual perception can reach beyond the limits of weakness and involve high-level properties as well. By high-level property, it’s meant properties such as natural/artificial/functional kind, causality, dispositional properties, gender, roughness, aesthetic properties, bodily sensations, states of mind, agency features, action features, and moral properties. In this dissertation, setting Susanna Siegel's rich (...) content thesis as a framework and relying on her method of phenomenal contrast as a way of discovering the contents, I am intending to assess an account of perceiving moral properties. I will impose two objections against this model: The first one invokes the ignored role of imagination and recollection in the method and generally targets the method of contrast. The second one invokes the thesis of phenomenal holism and targets specifically the machinery of drawing contrast in the proposed moral pair. Finally, I’ll conclude that this account of moral perception, as well as other phenomenal-contrast-based accounts, is not tenable. -/- . (shrink)

In this paper, we defend three claims about what it will take for an AI system to be a basic moral patient to whom we can owe duties of non-maleficence not to harm her and duties of beneficence to benefit her: (1) Moral patients are mental patients; (2) Mental patients are true intentional systems; and (3) True intentional systems are systematically flexible. We suggest that we should be particularly alert to the possibility of such systematically flexible true intentional systems developing (...) in the areas of exploratory robots and artificial personal assistants. Finally, we argue that in light of our failure to respect the well-being of existing biological moral patients and worries about our limited resources, there are compelling moral reasons to treat artificial moral patiency as something to be avoided at least for now.

This is a bibliography of books and articles on consciousness in philosophy, cognitive science, and neuroscience over the last 30 years. There are three main sections, devoted to monographs, edited collections of papers, and articles. The first two of these sections are each divided into three subsections containing books in each of the main areas of research. The third section is divided into 12 subsections, with 10 subject headings for philosophical articles along with two additional subsections for articles in cognitive (...) science and neuroscience. Of course the division is somewhat arbitrary, but I hope that it makes the bibliography easier to use. This bibliography has first been compiled by Thomas Metzinger and David Chalmers to appear in print in two philosophical anthologies on conscious experience . From 1995 onwards it has been continuously updated by Thomas Metzinger, and now is freely available as a PDF-, RTF-, or HTML-file. This bibliography mainly attempts to cover the Anglo-Saxon and German debates, in a non-annotated, fully formatted way that makes it easy to "cut and paste" from the original file. To a certain degree this bibliography also contains items in other languages than English and German - all submissions in other languages are welcome. Last update of current version: July 13th, 2001.

‘What it is like’ talk (‘WIL-talk’) — the use of phrases such as ‘what it is like’ — is ubiquitous in discussions of phenomenal consciousness. It is used to define, make claims about, and to offer arguments concerning consciousness. But what this talk means is unclear, as is how it means what it does: how, by putting these words in this order, we communicate something about consciousness. Without a good account of WIL-talk, we cannot be sure this talk sheds light, (...) rather than casts shadows, on our investigations of consciousness. The popular technical account of WIL-talk (see e.g. Lewis, 1995, and Kim, 1998) holds that WIL-talk involves technical terms — terms which look like everyday words but have a distinct meaning — introduced by philosophers. I argue that this account is incorrect by showing that the alleged technical terms were not introduced by philosophers, and that these terms do not have a technical meaning. (shrink)

According to Carruthers ants and bees have minds. This claim is to be understood realistically. We do not interpret the overt behaviour of ants and bees by ascribing to them beliefs and desires in an instrumental manner. They rather possess minds in the relevant cognitive sense. In this paper, I propose to pave the way for a reductio against such a polemic view. In particular, I shall argue that if ants and bees have minds, by the same token, plants do (...) have minds too. In my view, the problem has to do with Carruthers' underlying technical concept of cognitive architecture; a concept which, as I shall argue, can be called into question both on empirical and conceptual grounds. Según Carruthers, las hormigas y las abejas tienen mente. Esta afirmación debe entenderse de modo realista. No es que interpretemos la conducta abierta de hormigas y abejas en términos de creencias y deseos atribuidos instrumentalmente. Se trata más bien de que tienen tales estados mentales en el sentido cognitivo relevante. En este trabajo, me propongo llevar esta polémica concepción a una reductio. En particular, argumentaré que si las hormigas y las abejas tienen mente, por la misma razón las plantas también la tendrían. A mi modo de ver, el problema tiene que ver con el concepto técnico de arquitectura cognitiva de Carruthers ; un concepto que puede ser cuestionado sobre bases empíricas y conceptuales, según argüiré.
