This article provides the foundation for a new predictive theory of animal learning that is based upon a simple logical model. The knowledge of experimental subjects at a given time is described using logical equations. These logical equations are then used to predict a subject’s response when presented with a known or a previously unknown situation. This new theory suc- cessfully anticipates phenomena that existing theories predict, as well as phenomena that they cannot. It provides a theoretical account for phenomena (...) that are beyond the domain of existing models, such as extinction and the detection of novelty, from which “external inhibition” can be explained. Examples of the methods applied to make predictions are given using previously published results. The present theory proposes a new way to envision the minimal functions of the nervous system, and provides possible new insights into the way that brains ultimately create and use knowledge about the world.

Beckers et al. (2006) published intriguing results, obtained in the rat fear condi- tioning paradigm, challenging classical associativist theories of learning. One of the main findings of Beckers et al. (2006) is that what they called subad- ditive pretraining abolished the expres- sion of blocking. Haselgrove (2010) proposed an expla- nation, based on the well known Rescorla- Wagner Model (Rescorla and Wagner, 1972). We will demonstrate here that the account offered by Haselgrove (2010) is contradictory to the basic assumptions of (...) the Rescorla-Wagner Model. (shrink)

The scientific understanding of cognition and consciousness is currently hampered by the lack of rigorous and universally accepted definitions that permit comparative studies. This paper proposes new functional and un- ambiguous definitions for cognition and consciousness in order to provide clearly defined boundaries within which general theories of cognition and consciousness may be developed. The proposed definitions are built upon the construction and manipulation of reality representation, decision making and learning and are scoped in terms of an underlying logical structure. (...) It is argued that the presentation of reality also necessitates the concept of ab- sence and the capacity to perform transitive inference. Explicit predictions relating to these new definitions, along with possible ways to test them, are also described and discussed. (shrink)

Despite numerous and increasing attempts to define what life is, there is no consensus on necessary and sufficient conditions for life. Accordingly, some scholars have questioned the value of definitions of life and encouraged scientists and philosophers alike to discard the project. As an alternative to this pessimistic conclusion, we argue that critically rethinking the nature and uses of definitions can provide new insights into the epistemic roles of definitions of life for different research practices. This paper examines the possible (...) contributions of definitions of life in scientific domains where such definitions are used most (e.g., Synthetic Biology, Origins of Life, Alife, and Astrobiology). Rather than as classificatory tools for demarcation of natural kinds, we highlight the pragmatic utility of what we call operational definitions that serve as theoretical and epistemic tools in scientific practice. In particular, we examine contexts where definitions integrate criteria for life into theoretical models that involve or enable observable operations. We show how these definitions of life play important roles in influencing research agendas and evaluating results, and we argue that to discard the project of defining life is neither sufficiently motivated, nor possible without dismissing important theoretical and practical research.

First published in 1965, this collection of three essays by influential German philosopher Karl Jaspers deals with the response of the philosophical mind to the world of reality, with the search for truth. In Leonardo, this search is shown in the thinking and the works of a supreme artist whose means of apperception are the senses. The essay on Max Weber commemorates a man Jaspers knew personally and ardently admired. The main essay in the collection is an exhaustive, three (...) part study of Descartes: analysing Descartes’ new philosophical operation, Descartes’ Method, and the position of his philosophy within the wider historical context of philosophical thought.

Living organisms act as integrated wholes to maintain themselves. Individual actions can each be explained by characterizing the mechanisms that perform the activity. But these alone do not explain how various activities are coordinated and performed versatilely. We argue that this depends on a specific type of mechanism, a control mechanism. We develop an account of control by examining several extensively studied control mechanisms operative in the bacterium E. coli. On our analysis, what distinguishes a control mechanism from other mechanisms (...) is that it relies on measuring one or more variables, which results in setting constraints in the control mechanism that determine its action on flexible constraints in other mechanisms. In the most basic arrangement, the measurement process directly determines the action of the control mechanism, but in more complex arrangements signals mediate between measurements and effectors. This opens the possibility of multiple responses to the same measurement and responses based on multiple measurements. It also allows crosstalk, resulting in networks of control mechanisms. Such networks integrate the behaviors of the organism but also present a challenge in tailoring responses to particular measurements. We discuss how integrated activity can still result in differential, versatile, responses. (shrink)

The interconnection of scientific studies and art represented by Leonardo Da Vinci’s portraiture accentuates his role in documenting and archiving dermatologic conditions. His anatomical dissections, sketches, and paintings, including portraits, were all a means to observe, portray, and understand the nuances of the human body. In two of his most discussed portraits, Ginevra de’ Benci and Elisabetta del Giocondo, the Mona Lisa, Leonardo’s execution of the exterior anatomy is so precise that he may have illustrated manifestations of disease (...) that allow contemporary researchers to theorize diagnoses of dermatologic as well as neurologic, endocrine and vascular conditions. These include hypochromic anemia, muscular disorders, xanthelasma, thyroid disease, lipoma, and frontal fibrosing alopecia. Leonardo’s extraordinary talent in recording his observations of shades and textures of skin and his ability to capture the nuances of subtle variations in the human body have produced a historical record that allows modern dermatology practitioners to make further observations not possible in his time. Here, dermatology and art intersect serving to document and explain the human condition, permanently archived in Leonardo’s masterpieces. (shrink)

Organization figures centrally in the understanding of biological systems advanced by both new mechanists and proponents of the autonomy framework. The new mechanists focus on how components of mechanisms are organized to produce a phenomenon and emphasize productive continuity between these components. The autonomy framework focuses on how the components of a biological system are organized in such a way that they contribute to the maintenance of the organisms that produce them. In this paper we analyze and compare these two (...) accounts of organization and argue that understanding biological organisms as cohesively integrated systems benefits from insights from both. To bring together the two accounts, we focus on the notions of control and regulation as bridge concepts. We start from a characterization of biological mechanisms in terms of constraints and focus on a specific type of mechanism, control mechanisms, that operate on other mechanisms on the basis of measurements of variables in the system and its environment. Control mechanisms are characterized by their own set of constraints that enable them to sense conditions, convey signals, and effect changes on constraints in the controlled mechanism. They thereby allow living organisms to adapt to internal and external variations and to coordinate their parts in such a manner as to maintain viability. Because living organisms contain a vast number of control mechanisms, a central challenge is to understand how they are themselves organized. With the support of examples from both unicellular and multicellular systems we argue that control mechanisms are organized heterarchically, and we discuss how this type of control architecture can, without invoking top-down and centralized forms of organizations, succeed in coordinating internal activities of organisms.

Biological regulation is what allows an organism to handle the effects of a perturbation, modulating its own constitutive dynamics in response to particular changes in internal and external conditions. With the central focus of analysis on the case of minimal living systems, we argue that regulation consists in a specific form of second-order control, exerted over the core regime of production and maintenance of the components that actually put together the organism. The main argument is that regulation requires a distinctive (...) architecture of functional relationships, and specifically the action of a dedicated subsystem whose activity is dynamically decoupled from that of the constitutive regime. We distinguish between two major ways in which control mechanisms contribute to the maintenance of a biological organisation in response to internal and external perturbations: dynamic stability and regulation. Based on this distinction an explicit definition and a set of organisational requirements for regulation are provided, and thoroughly illustrated through the examples of bacterial chemotaxis and the lac-operon. The analysis enables us to mark out the differences between regulation and closely related concepts such as feedback, robustness and homeostasis. (shrink)

College cheating is prevalent, with rates ranging widely from 9 to 95% (Whitley, 1998). Research has been exclusively conducted with enrolled college students. This study examined the prevalence of cheating in a sample of college alumni, who risk less in disclosing academic dishonesty than current students. A total of 273 alumni reported on their prevalence and perceived severity of 19 cheating behaviors. The vast majority of participants (81.7%) report having engaged in some form of cheating during their undergraduate career. The (...) most common forms of cheating were “copying from another student's assignment” and “allowing others to copy from your assignment.” More students reported cheating in classes for their major than other classes. Males and females cheated at the same rates in classes for their major, and males reported higher rates of cheating than females in nonmajor classes. Respondents reported that their top reasons for cheating were “lack of time” and “to help a friend.”. (shrink)

Endocrinologists apply the idea of feedback loops to explain how hormones regulate certain bodily functions such as glucose metabolism. In particular, feedback loops focus on the maintenance of the plasma concentrations of glucose within a narrow range. Here, we put forward a different, organicist perspective on the endocrine regulation of glycaemia, by relying on the pivotal concept of closure of constraints. From this perspective, biological systems are understood as organized ones, which means that they are constituted of a set of (...) mutually dependent functional structures acting as constraints, whose maintenance depends on their reciprocal interactions. Closure refers specifically to the mutual dependence among functional constraints in an organism. We show that, when compared to feedback loops, organizational closure can generate much richer descriptions of the processes and constraints at play in the metabolism and regulation of glycaemia, by making explicit the different hierarchical orders involved. We expect that the proposed theoretical framework will open the way to the construction of original mathematical models, which would provide a better understanding of endocrine regulation from an organicist perspective.

The new mechanists and the autonomy approach both aim to account for how biological phenomena are explained. One identifies appeals to how components of a mechanism are organized so that their activities produce a phenomenon. The other directs attention towards the whole organism and focuses on how it achieves self-maintenance. This paper discusses challenges each confronts and how each could benefit from collaboration with the other: the new mechanistic framework can gain by taking into account what happens outside individual mechanisms, (...) while the autonomy approach can ground itself in biological research into how the actual components constituting an autonomous system interact and contribute in different ways to realize and maintain the system. To press the case that these two traditions should be constructively integrated we describe how three recent developments in the autonomy tradition together provide a bridge between the two traditions: (1) a framework of work and constraints, (2) a conception of function grounded in the organization of an autonomous system, and (3) a focus on control.

Resumo Este artigo procura apresentar e discutir tentativas recentes em filosofia social de analisar e interpretar o capitalismo, a partir de uma perspectiva praxeológica. O practice turn em teoria social procurou superar o dualismo entre agência e estrutura, ou entre ação e sistema, por meio da noção de prática social. Seria possível então interpretar o capitalismo como um tipo especifico de prática social? Para tentar encaminhar essa questão, explicita-se brevemente, em um primeiro momento, em que consiste o practice turn em (...) teoria social. Num segundo momento, analisa-se e se discute a proposta de Rahel Jaeggi de conceber a economia como uma rede de práticas sociais. Em seguida, expõe-se e se avalia a tentativa de Christian Lotz em ver, no dinheiro, a chave para compreender aquilo que ele chama de esquema capitalista. Por fim, conclui-se, chamando a atenção para os potenciais e desafios ligados ao empreendimento de interpretar o capitalismo em função de uma teoria da prática, sugerindo que um aprofundamento na análise da imaginação especificamente capitalista, vinculando-a com a típica plasticidade e diversidade do capitalismo, possa ajudar a avançar nesse campo.This paper aims to present and discuss recent attempts in social philosophy to analyze and interpret capitalism from a praxeological perspective. The practice turn in social theory sought to overcome the dualism between agency and structure, or between action and system, through the notion of social practice. Is it then possible to interpret capitalism as a specific type of social practice? To try to address this question, I briefly introduce, in a first moment, the practice turn in social theory. In a second moment, I analyze and discuss Rahel Jaeggi’s proposal to conceive the economy as a network of social practices. I then explain and evaluate Christian Lotz’s attempt to see money as the key to understanding what he names as “the capitalist schema”. Finally, I conclude by drawing attention to the potentials and challenges of interpreting capitalism as a social practice, suggesting that a deeper analysis of specifically capitalist imagination, linking it with the typical plasticity and diversity of capitalism, may help to move forward in this field.

In this paper we address the question of minimal cognition by investigating the origin of some crucial cognitive properties from the very basic organisation of biological systems. More specifically, we propose a theoretical model of how a system can distinguish between specific features of its interaction with the environment, which is a fundamental requirement for the emergence of minimal forms of cognition. We argue that the appearance of this capacity is grounded in the molecular domain, and originates from basic mechanisms (...) of biological regulation. In doing so, our aim is to provide a theoretical account that can also work as a possible conceptual bridge between Synthetic Biology and Artificial Intelligence. In fact, we argue, Synthetic Biology can contribute to the study of minimal cognition, by providing a privileged approach to the study of these mechanisms by means of artificial systems. (shrink)

In this article an epistemological framework is proposed in order to integrate the emergentist thought with systemic studies on biological autonomy, which are focused on the role of organization. Particular attention will be paid to the role of the observer’s activity, especially: (a) the different operations he performs in order to identify the pertinent elements at each descriptive level, and (b) the relationships between the different models he builds from them. According to the approach sustained here, organization will be considered (...) as the result of a specific operation of identification of the relational properties of the functional components of a system, which do not necessarily coincide with the intrinsic properties of its structural constituents. Also, an epistemological notion of emergence—that of “complex emergence”—will be introduced, which can be defined as the insufficiency, even in principle, of a single descriptive modality to provide a complete description of certain classes of systems. This integrative framework will allow us to deal with two issues in biological and emergentist studies: (1) distinguishing the autonomy proper of living systems from some physical processes like those of structural stability and pattern generation, and (2) reconsidering the notion of downward causation not as a direct or indirect influence of the whole on its parts, but instead as an epistemological problem of interaction between descriptive domains in which the concept of organization proposed and the observational operations related to it play a crucial role.
