The goal of the article is to show that a complete answer to the title question can be given only in the context of the natural sciences. We believe that the group of cognitive sciences are the most reliable source of information about cognitive mental processes is. Making use of their achievements, we present a series of criteria for possessing a mind. We distinguish between many kinds of minds. We attempt to outline the conditions that must be fulfilled by an adequate model of the mind. In our opinion, such a model must make use of all available empirical data and of scientific theories constructed on the basis of such data. From the point of view of philosophy, the requirements placed upon such theories by ontology are especially important. Their reconstruction can be a prolegomenon to a future integrated ontology of the mind. We emphasize that the mind is not an independent thing. In speaking about the mind we have in mind states, events, processes, functions, and dispositions that are derivative with respect to processes of a lower order. We assume that an adequate model of the mind is multi-dimensional, taking into account several mutually interacting levels of organization. We interpret the psychophysical problem as one of the relation between levels of organization, a relation that is constitutive for the actualization of mental states. Psychophysical relations turn out to be a particular case of the broader issue of relations between levels. In carrying out a preliminary conceptualization we make use of the notion of emergence; this is why our position, which is mainly in opposition to substantial dualism, may be termed emergent monism or naturalism

The paper defends the claim that the mechanistic explanation of information processing is the fundamental kind of explanation in cognitive science. These mechanisms are complex organized systems whose functioning depends on the orchestrated interaction of their component parts and processes. A constitutive explanation of every mechanism must include both appeal to its environment and to the role it plays in it. This role has been traditionally dubbed competence. To fully explain how this role is played it is necessary to explain the information processing inside the mechanism embedded in the environment. The most usual explanation on this level has a form of a computational model, for example a software program or a trained artificial neural network. However, this is not the end of the explanatory chain. What is left to be explained is how the program is realized (or what processes are responsible for information processing in the artificial neural network). By using two dramatically different examples from the history of cognitive science I show the multi-level structure of explanations in cognitive science. These examples are (1) the explanation of human process solving as proposed by A. Newell & H. Simon; (2) the explanation of cricket phonotaxis via robotic models by B. Webb.

The paper proposes an empirical method to investigate linguistic prescriptions as inherent corrective behaviors. The behaviors in question may but need not necessarily be supported by any explicit knowledge of rules. It is possible to gain insight into them, for example by extracting information about corrections from revision histories of texts (or by analyzing speech corpora where users correct themselves or one another). One easily available source of such information is the revision history of Wikipedia. As is shown, the most frequent and short corrections are limited to linguistic errors such as typos (and editorial conventions adopted in Wikipedia). By perusing an automatically generated revision corpus, one gains insight into the prescriptive nature of language empirically. At the same time, the prescriptions offered are not reducible to descriptions of the most frequent linguistic use.

Explanations in cognitive science and computational neuroscience rely predominantly on computational modeling. Although the scientific practice is systematic, and there is little doubt about the empirical value of numerous models, the methodological account of computational explanation is not up-to-date. The current chapter offers a systematic account of computational explanation in cognitive science and computational neuroscience within a mechanistic framework. The account is illustrated with a short case study of modeling of the mirror neuron system in terms of predictive coding.

In Darwin’s Dangerous Idea, Daniel Dennett claims that evolution is algorithmic. On Dennett’s analysis, evolutionary processes are trivially algorithmic because he assumes that all natural processes are algorithmic. I will argue that there are more robust ways to understand algorithmic processes that make the claim that evolution is algorithmic empirical and not conceptual. While laws of nature can be seen as compression algorithms of information about the world, it does not follow logically that they are implemented as algorithms by physical processes. For that to be true, the processes have to be part of computational systems. The basic difference between mere simulation and real computing is having proper causal structure. I will show what kind of requirements this poses for natural evolutionary processes if they are to be computational.

Artificial models of cognition serve different purposes, and their use determines the way they should be evaluated. There are also models that do not represent any particular biological agents, and there is controversy as to how they should be assessed. At the same time, modelers do evaluate such models as better or worse. There is also a widespread tendency to call for publicly available standards of replicability and benchmarking for such models. In this paper, I argue that proper evaluation ofmodels does not depend on whether they target real biological agents or not; instead, the standards of evaluation depend on the use of models rather than on the reality of their targets. I discuss how models are validated depending on their use and argue that all-encompassing benchmarks for models may be well beyond reach

The contributors to this volume engage with issues of normativity within naturalised philosophy. The issues are critical to naturalism as most traditional notions in philosophy, such as knowledge, justification or representation, are said to involve normativity. Some of the contributors pursue the question of the correct place of normativity within a naturalised ontology, with emergentist and eliminativist answers offered on neighbouring pages. Others seek to justify particular norms within a naturalised framework, the more surprising ones including naturalist takes on the a priori and intuitions. Finally, yet others examine concrete examples of the application of norms within particular epistemic endeavours, such as psychopathology and design. The overall picture is that of an intimate engagement with issues of normativity on the part of naturalist philosophers – questioning some of the fundamentals at the same time as they try to work out many of the details.

In this paper, I argue that even if the Hard Problem of Content, as identified by Hutto and Myin, is important, it was already solved in natu- ralized semantics, and satisfactory solutions to the problem do not rely merely on the notion of information as covariance. I point out that Hutto and Myin have double standards for linguistic and mental representation, which leads to a peculiar inconsistency. Were they to apply the same standards to basic and linguistic minds, they would either have to embrace representationalism or turn to semantic nihilism, which is, as I argue, an unstable and unattractive position. Hence, I conclude, their book does not offer an alternative to representation- alism. At the same time, it reminds us that representational talk in cognitive science cannot be taken for granted and that information is different from men- tal representation. Although this claim is not new, Hutto and Myin defend it forcefully and elegantly.

Autor artykułu broni tezy, że niektóre systemy obliczeniowe mogą mieć własności semantyczne. Wskazana została klasa systemów obliczeniowych, w których reprezentacje mogą mieć przynajmniej dwie własności: własność odnoszenia się do obiektów (desygnowanie) i własność wspomagania rozpoznawania obiektów oznaczanych przez daną reprezentację (konotowanie). Autor argumentuje także, że własności semantyczne reprezentacji nie zależą wyłącznie od architektury systemów obliczeniowych, w których te reprezentacje występują. Konkretna architektura obliczeniowa nie jest czynnikiem kluczowym, a bodaj najmniej istotne są same rodzaje struktur danych, które mają mieć własności desygnowania czy konotowania. Własność desygnowania czy konotowania nie musi być zlokalizowana w samych reprezentacjach, może być własnością wyższego rzędu, powstającą w mechanizmie wyższego poziomu. Własności semantyczne reprezentacji mogą być wielorako realizowane. Systemy klasyczne, koneksjonistyczne czy też hybrydowe mogą równie dobrze mieć własności semantyczne, jak ich nie mieć

In this chapter, I argue that some aspects of cognitive phenomena cannot be explained computationally. In the first part, I sketch a mechanistic account of computational explanation that spans multiple levels of organization of cognitive systems. In the second part, I turn my attention to what cannot be explained about cognitive systems in this way. I argue that information-processing mechanisms are indispensable in explanations of cognitive phenomena, and this vindicates the computational explanation of cognition. At the same time, it has to be supplemented with other explanations to make the mechanistic explanation complete, and that naturally leads to explanatory pluralism in cognitive science. The price to pay for pluralism, however, is the abandonment of the traditional autonomy thesis asserting that cognition is independent of implementation details.

Nietzsche's treatment of Epicurus is an interesting example of philosophical hermeneutics. Epicurus bas tren notoriously misinterpreted, claims Nietzsche, because bis mask bas been taken for bis true face. Traditionally Epicurus is presented as a utilitarian or hedonist avant la lettre. This is a simplification motivated by a desire to deprecate bis philosophy. To Nietzsche Epicurus was „an idyllic hero”, a teacher with anistocratic predilections aun his own concept of good, critical of the traditional form of religion, and of the „pre-existent form of Cbristianity”. As a hedonist he was much less convincing, as he was afraid of both pain and pleasure. He assumed the mask of an epicure in order to hide bis true self. Nietzsche warn us over and over again not to trust the traditional interpretation of Epicurus and urges us to penetrate beyond the veil of a stylish disguise.

In most accounts of realization of computational processes by physical mechanisms, it is presupposed that there is one-to-one correspondence between the causally active states of the physical process and the states of the computation. Yet such proposals either stipulate that only one model of computation is implemented, or they do not reflect upon the variety of models that could be implemented physically. In this paper, I claim that mechanistic accounts of computation should allow for a broad variation of models of computation. In particular, some non-standard models should not be excluded a priori. The relationship between mathematical models of computation and mechanistically adequate models is studied in more detail.

In this paper, I suggest that the notion of module explicitly defined by Peter Carruthers in The Architecture of The Mind (Carruthers 2006) is not really In use in the book. Instead, a more robust notion seems to be actually in play. The more robust notion, albeit implicitly assumed, seems to be far more useful for making claims about the modularity of mind. Otherwise, the claims would become trivial. This robust notion will be reconstructed and improved upon by putting it into a more general framework of mental architecture. I defend the view that modules are the outcome of structural rather than functional decomposition and that they should be conceived as near decomposable systems.

In this paper, the role of the environment and physical embodiment of computational systems for explanatory purposes will be analyzed. In particular, the focus will be on cognitive computational systems, understood in terms of mechanisms that manipulate semantic information. It will be argued that the role of the environment has long been appreciated, in particular in the work of Herbert A. Simon, which has inspired the mechanistic view on explanation. From Simon’s perspective, the embodied view on cognition seems natural but it is nowhere near as critical as its proponents suggest. The only point of difference between Simon and embodied cognition is the significance of body-based off-line cognition; however, it will be argued that it is notoriously over-appreciated in the current debate. The new mechanistic view on explanation suggests that even if it is critical to situate a mechanism in its environment and study its physical composition, or realization, it is also stressed that not all detail counts, and that some bodily features of cognitive systems should be left out from explanations.

Multiple realizability (MR) is traditionally conceived of as the feature of computational systems, and has been used to argue for irreducibility of higher-level theories. I will show that there are several ways a computational system may be seen to display MR. These ways correspond to (at least) five ways one can conceive of the function of the physical computational system. However, they do not match common intuitions about MR. I show that MR is deeply interest-related, and for this reason, difficult to pin down exactly. I claim that MR is of little importance for defending computationalism, and argue that it should rather appeal to organizational invariance or substrate neutrality of computation, which are much more intuitive but cannot support strong antireductionist arguments.

The claim defended in the paper is that the mechanistic account of explanation can easily embrace idealization in big-scale brain simulations, and that only causally relevant detail should be present in explanatory models. The claim is illustrated with two methodologically different models: Blue Brain, used for particular simulations of the cortical column in hybrid models, and Eliasmith’s SPAUN model that is both biologically realistic and able to explain eight different tasks. By drawing on the mechanistic theory of computational explanation, I argue that large-scale simulations require that the explanandum phenomenon is identified; otherwise, the explanatory value of such explanations is difficult to establish, and testing the model empirically by comparing its behavior with the explanandum remains practically impossible. The completeness of the explanation, and hence of the explanatory value of the explanatory model, is to be assessed vis-à-vis the explanandum phenomenon, which is not to be conflated with raw observational data and may be idealized. I argue that idealizations, which include building models of a single phenomenon displayed by multi-functional mechanisms, lumping together multiple factors in a single causal variable, simplifying the causal structure of the mechanisms, and multi-model integration, are indispensable for complex systems such as brains; otherwise, the model may be as complex as the explanandum phenomenon, which would make it prone to so-called Bonini paradox. I conclude by enumerating dimensions of empirical validation of explanatory models according to new mechanism, which are given in a form of a “checklist” for a modeler

The purpose of this paper is to present a general mechanistic framework for analyzing causal representational claims, and offer a way to distinguish genuinely representational explanations from those that invoke representations for honorific purposes. It is usually agreed that rats are capable of navigation because they maintain a cognitive map of their environment. Exactly how and why their neural states give rise to mental representations is a matter of an ongoing debate. I will show that anticipatory mechanisms involved in rats’ evaluation of possible routes give rise to satisfaction conditions of contents, and this is why they are representationally relevant for explaining and predicting rats’ behavior. I argue that a naturalistic account of satisfaction conditions of contents answers the most important objections of antirepresentationalists

In this paper, I focus on a problem related to teleological theories of content namely, which notion of function makes content causally relevant? It has been claimed that some functional accounts of content make it causally irrelevant, or epiphenomenal; in which case, such notions of function could no longer act as the pillar of naturalized semantics. By looking closer at biological questions about behavior, I argue that past discussion has been oriented towards an ill-posed question. What I defend is a Very Boring Hypothesis: depending on the representational phenomenon and the explanatory question, different aspects might be important, and it is difficult to say a priori which ones these might be. There are multiple facets to biological functionality and causality relevant for explaining representational phenomena, and ignoring them will lead to unmotivated simplifications. In addition, accounting for different facets of functionality helps dispense with intuition-based specifications of cognitive phenomena.
