Disputes about the causal structure of natural selection have implications for teleosemantics. Etiological, mainstream teleosemantics is based on a causalist view of natural selection. The core of its solution to Brentano’s Problem lies in the solution to Kant’s Puzzle provided by the Modern Synthesis concerning populational causation. In this paper, I suggest that if we adopt an alternative, statisticalist view on natural selection, the door is open for two reflections. First, it allows for setting different challenges to etiological teleosemantics that (...) arise if a statisticalist reading of natural selection is right. Second, by providing a different solution to Kant’s Puzzle based on individual causes of evolution, statisticalism promotes a different answer to Brentano’s Problem, what I label as Agential Teleosemantics.

Abstract: This paper argues that a central explanatory role for the concept of Umwelt in theoretical biology is to be found in developmental biology, in particular in the effort to understand development as a goal-directed and adaptive process that is controlled by the organism itself. I will reach this conclusion in two (interrelated) ways. The first is purely theoretical and relates to the current scenario in the philosophy of biology. Challenging neo-Darwinism requires a new understanding of the various components involved (...) in natural selection processes. An important prerequisite for the explanation is the ability to understand development in a teleological way. Here, the concept of Umwelt plays a crucial role: if organisms are responsible for generating adaptive variation in specific environments, we need a theory that explains the context-dependent nature of adaptively oriented processes. The Umwelt is thus a central element in determining the goal that an adaptive process pursues. The second path in my analysis also has a historical dimension. I will present Karl Ernst von Baer’s reflections on teleological development and his influence on von Uexküll's thinking. I will present various ideas developed by von Baer, such as the distinction between Ziel and Zweck and the use of musical metaphors, which can help to understand development teleologically and give von Uexküll’s theory a central place in this framework.

The field of the philosophy of biology is flourishing in its aim to evaluate and rethink the view inherited from the previous century ---the Modern Synthesis. Different research areas and theories have come to the fore in the last decades in order to account for different biological phenomena that, in the first instance, fall beyond the explanatory scope of the Modern Synthesis. This thesis is anchored and motivated by this revolt in the philosophy of biology. -/- The central target in (...) this context is the possibility of naturalizing teleology, a classical nightmare for the history of biology itself. This requires, principally, understanding the causes of teleological explanations without assuming an unfashioned backward causation of sorts. As the riddles of teleological explanations are about their temporal dimension, I analyze different temporal scales of biological processes: evolutionary, developmental, and physiological. -/- The first one is the one defended in the context of the Modern Synthesis. As expected, one of the aims of this thesis is to evaluate the adequacy of an evolutionary account of teleological explanation. The scrutiny is negative. Evolutionary explanations in the context of the Modern Synthesis lack the necessary causal roots to naturalize teleology. Concerning the physiological scale, a long tradition pushed up by Kant and the organicist movement in the 20th century allows us to better understand how teleological explanations can be naturalized in physiological process. The key notions in this temporal scale are self-organization and the recursive, looped character of physiological process. While the physiological scale may be suitably accounted by contemporaries views, such as Autonomous Systems Theory, different central teleological phenomena remain unexplained from a purely physiological perspective. In particular, different issues concerning the (adaptive) construction of organism ---such as plasticity, robustness, variation, novelty, inheritance--- deserve an ontogenetic analysis. -/- The principal aim of this thesis is to provide a theory of teleological development that falls beyond the Modern Synthesis' framework and is prompted by different insights from the history of biology. I call it Agential Teleosemantics. It rests on two central pillars. First, that developmental processes, beyond any gene-centered stance, can be understood in informational terms; i.e. developmental processes are about the interaction of developmental resources conveying biological information. The second ingredient is agentivity, namely the idea that development is regulated by an agentive system according to the adaptiveness of the phenotypic outcomes produced. The role of agency in Agential Teleosemantic is equivalent to the role of genes in the Modern Synthesis: it is responsible for explaining the order and the adaptive complexity in the living realm. -/- The second target of this thesis regards the possibility of naturalizing intentional explanations in cognitive science. The central project involved in such an aim is known as teleosemantics. Classical teleosemantics however is etiological: it explains the teleofunctions of representational systems in terms of evolutionary processes. The different disputes in the contemporary philosophy of biology provide two insights to analyze teleosemantics in cognitive science. First, the challenges against the Modern Synthesis must be extended to the evolutionary approach of etiological teleosemantics. Second, as Agential Teleosemantics suggests an alternative source for teleofunctions ---ontogeny, I offer an attempt to integrate Agential Teleosemantics into cognitive science in order to provide an alternative teleosemantic project to understand intentional explanations in cognitive science.

The foundations of biology have been a topic of debate for the past few decades. The traditional perspective of the Modern Synthesis, which portrays organisms as passive entities with limited role in evolutionary theory, is giving way to a new paradigm where organisms are recognized as active agents, actively shaping their own phenotypic traits for adaptive purposes. Within this context, this article raises the question of whether contemporary biological theory is undergoing a cognitive revolution. This inquiry can be approached in (...) two ways: from a theoretical standpoint, exploring the centrality of the cognitive sciences in current theoretical biology; and from a historical perspective, examining the resemblance between the current state of theoretical biology and the Cognitive Revolution of the mid-20th century. Both inquiries yield affirmative answers, though important nuances will be emphasized. The cognitive sciences' explanatory framework is employed to elucidate the agentic characteristics of organisms, establishing a clear parallelism between the Cognitive Revolution and the present state of theoretical biology.

Abstract: A common explanatory error concerns conflating epistemological roles between two domains. Here I deal with a special case: when explanations of development replace evolutionary explanations or vice versa. Ernst Mayr famously distinguished between proximate and ultimate causal explanations in biology. His view was central to keeping development outside the theory of evolution. Nevertheless, the explanatory role of developmental processes in evolution is a central theme in current theoretical biology, which has led to several revisions of Mayr’s distinction. In the (...) following, I will review these reviewers to determine whether the integration of development and evolution is based on an appropriate reinterpretation of Mayr’s distinction. The revisionists often propose an interactionist alternative in which proximate and ultimate causes interact to produce evolved traits. The most common interactionist account relies on the idea of reciprocal causation. I will argue that this perspective is still problematic and that the boundaries between explanatory domains are crossed. Instead, we should rethink Mayr’s distinction by adopting an alternative view of evolutionary causation, the so-called Statisticalist view on natural selection, which claims that the only level of causation is the proximate level. By excluding two different levels of causation, this framework is able to avoid fallacious explanations and fully consider reciprocal causation as a proximate phenomenon. I introduce the concept of “statistical reciprocity” to explain the statistical effects of (proximate) reciprocal causation in ultimate explanations and outline some ideas of “population ontogenetics” as a prominent framework for unifying development and evolution beyond interactionist positions.

The use of evolutionary explanations to explain phenomena at the individual level has been described by various authors as an explanatory error, the so-called Phylogeny Fallacy. In this paper, this fallacy will be analyzed in the context of teleosemantics, a central project of the philosophy of mind whose main aim is to naturalize intentional systems by appealing to their biological teleofunctions. I will argue that those teleosemantics projects that invoke evolutionary functions generally commit the fallacy. First, I will point to (...) various arguments in the literature that point to this fallacy. However, a more general argument will also be made. To illustrate this puzzling scenario, I will present two desiderata that any teleosemantic project must fulfill. I will argue that naturalizing intentionality based on natural selection creates an explanatory gap between types and tokens. This gap prohibits an adequate explanation of the desiderata. To close the gap, teleosemantics invokes replicator biology, a view of inheritance that has already been identified to commit the fallacy. This leads teleosemantics into a complex situation: to close the gap, it must commit the fallacy. (shrink)

Explanatory Externalism states that the only adaptive force in evolution is natural selection. Explanatory Externalism is a central thesis of the Modern Evolutionary Synthesis. The etiological theory of natural selected-effect functions also advocates Explanatory Externalism. According to this theory, natural selection is the process responsible for determining the proper natural functions of traits. However, I will point out several challenges to Explanatory Externalism that are proposed primarily by developmental biology and its various subfields. Based on these challenges, this paper will (...) argue why biological functions cannot be fully explained by the selected-effect theory, i.e., that a theory of biological functions must adopt some kind of Explanatory Internalism. At the end of this paper, I will discuss whether or not Explanatory Internalism entails a pluralistic view of biological functions, and how this discussion is related to the different explanations of fit and diversity found in evolutionary biology.

Abstract: The use of evolutionary explanations to account for proximate phenomena has been labeled by various authors as an explanatory error, the so-called phylogeny fallacy. In this paper, this fallacy will be analyzed in the context of teleosemantics. I will discuss whether teleosemantics projects that rely on the Selected-Effect Theory of Functions (i.e., mainstream teleosemantics) generally commit the fallacy. To frame the discussion, I will present two desiderata that, as argued here, every teleosemantic project must fulfill. The actuality desideratum, motivated (...) by Brentano’s problem, demands for a proximate analysis of the properties that make a system intentional. The historical desideratum, on the other hand, says that a teleological view of intentionality requires a historical dimension in order to understand the causal basis of teleological explanations. While I give some reasons why mainstream teleosemantics might be implicated in the phylogeny fallacy, my main argument aims to highlight an explanatory gap in mainstream teleosemantics: the population perspective on teleofunctions is inadequate to explain the proximate properties of intentional systems. In other words, the account of the historical desideratum in population-evolutionary terms prevents an adequate solution to the actuality desideratum. This is related to two central goals of teleosemantics: The goal of explaining content determination by recourse to natural selection processes makes it impossible to solve another goal of teleosemantics, the so-called problem of representational status. I analyze this situation and argue that inherited information (sometimes interpreted in a teleosemantic sense) plays the role of closing the gap. This leads teleosemantics into a complex situation: in order to close the gap, it must commit the fallacy. At the end of the article, I propose an alternative to fulfill both desiderata, motivated by an evo-devo perspective. I state that lineage explanations have the property of providing historical explanations based on proximate causes. (shrink)

El objetivo de este ensayo es analizar cómo confluyen en una misma base teórica tres discursos de diferentes áreas. Uno de ellos es la ciencia, mediante el genocentrismo defendido en la síntesis moderna en Biología. Otro es el de la religión, mediante la perspectiva finalista del alma y del diseño divino, que comparten las religiones abrahámicas. Y finalmente, en la esfera político-social, donde diferentes movimientos conservadores se oponen a replantear la agenda de derechos. La confluencia teórica que nuclea a las (...) tres áreas mencionadas es un preformismo sobre los organismos. Por lo tanto, primero, veremos cómo el preformismo se encuentra presente en biología. Segundo, señalaremos dos ideas relacionadas al preformismo que subyacen tanto en la biología como en la religión. Finalmente, analizaremos cómo ambos discursos, el científico y el religioso, se encuentran presentes y empleando un rol argumentativo en debates actuales sobre derechos humanos, específicamente, relacionados al aborto ya los derechos de la población lgtbiq+. La principal conclusión es que la síntesis moderna promueve erróneamente una defensa de un preformismo genético, con connotaciones religiosas, que es usado por movimientos conservadores en el ámbito político-social.
