Abstract: 

Living beings are the result of a cocktail made with unknown doses of chance and necessity. Consider a thought experiment, in which we could rewind the ‘tape of life’ starting from the same initial conditions, what biochemical traits and cellular features would finally be the same as those we observe today? It is clear that what is real in biology is a subset of what is possible, and this issue has been discussed at different scales. Thus, structural and dynamic developmental constraints limit the space of solutions for animal bodies (Alberch, 1989), whereas physicochemical restrictions and historical contingencies shape the possible at the molecular level (Jacob, 1981). Meteorite analysis and many organic syntheses performed under prebiotic conditions indicate that the primitive Earth was home of a moderately complicated chemodiversity, including the most common biological building blocks – sugars, fatty acids, amino acids, nucleobases, etc. (Lazcano, 2018). In this period of chemical evolution, physicochemical constraints (i.e. thermodynamics and kinetics in a given environment) determined the origin and maintenance of the abiotic chemical landscape. The chemically possible was the scenario for the organization of the most simple and primitive biochemical systems: autocatalytic cycles for self-maintenance of a set of building blocks, self-reproduction of lipid vesicles, and self-replication of genetic templates (Peretó, 2012). Presumably, all these cycles kicked off in the absence of catalysts or with the involvement of very simple and unspecific facilitators (e.g. mineral surfaces). The emergence of optimizable catalysts through natural selection (e.g. ribozymes) was a phase transition to a period of a more efficient and creative functional screening of the possible (de Duve, 2005). Diverse lines of evidence indicate that metabolic surveys of alternative sources of matter and energy were rapid and explosive, performed by the first microbial communities. Biogeochemical closing of the recycling of bioelements was a vital step for a sustainable and long-term continuity of terrestrial life (Falkowski et al., 2008). Thus, the boundaries of the metabolically possible were expanding in parallel to the coevolution of life and the planet. For instance, after the emergence in some cyanobacterial ancestors of the enzymatic machinery able to extract electrons from water to feed the photoelectronic chain, molecular oxygen accumulated in oceans and afterwards in the atmosphere. Those microorganisms able to cope with this new-to-life compound took advantage of its reactivity and dramatically expanded the world of the metabolically possible: many new metabolites, including steroids, and processes (e.g. oxygen respiration) became available to life. Thus, recurrent patterns in actual cell metabolisms are the result of a long evolutionary exploration within the chemically constrained space of the possible solutions under specific yet changing conditions (de Lorenzo et al., 2014).

IAS-Research Talk by Manuel Heras-Escribano (University of Granada) “Social normativity, fields of promoted action, and affordances: An integrative view”

On Nov 23rd, 2021, at 11:30.

To participate, please contact: alejandra.mtz.quintero@gmail.com

Abstract:

In this talk, I will show how social normativity, the field of promoted action, and canonical affordances are related. The field of promoted action is a concept proposed by Reed (1996), which is based on the idea that there are affordances emphasized by other people (Reed 1996: 130). Although proposed for the field of developmental psychology and experimentation, I think it is a rich concept to be applied to other fields (like philosophy of mind) to make sense of our everyday experience. But how could we articulate this idea? I propose that my ideas on social normativity (Heras-Escribano 2019) could serve as a framework for showing how the field of promoted action is constituted and present in everyone’s cognitive life. Also, I think the combination of the ideas of social normativity and the field of promoted action can help articulating the origins and nature of canonical affordances from a social perspective.

IAS-Research Talk Jo Bervoets (University of Antwerp), “Making sense of Tourettic sensibility (the joy of being let be?) “

On April 27, 2021, at 11:30.

To participate, please contact: guglielmo.militello@ehu.eus

Abstract: Tourettic tics are typically socially received as problematic and nonsensical. But there is a tension between this fact, and how individuals with Tourette’s make sense of their world. I resolve this tension by bridging phenomenological and post-phenomenological thinking via the concept of participatory sense-making. In doing so, I interpret Gilbert Simondon’s becoming of the individual being as participatory sense-making between the human and the non-human. I propose to view the Tourettic difference as an example of a particular way of being that becomes problematic only if it is not ‘let be,’ and as a prototype of playfulness when it is ‘let be’. In line with Simondon, the ethical primacy of our relational openness to such difference is seen as prerequisite of knowledge creation. In fact, I – provocatively – argue that ‘being human entails being mentally ill’ insofar as a deviation from social norms forms the precondition for the continued becoming of human knowledge. I tie dogmatic blocking of this becoming to ‘arrogant perception’ as elaborated by María Lugones. My talk is an outcome of a ‘virtual’ research visit with Hanne De Jaegher & Diana Beljaars, specialists in enaction/participatory sense-making and in post-phenomenolog/Tourette’s respectively.

Bio: Jo Bervoets holds Masters in Philosophy, in Cognitive Sciences and in Sciences (Electronic Engineering). He worked for 25 years in the technology sector. After a burn-out, Jo was diagnosed with autism in 2017. To get back on track he pursued his lifelong obsession with philosophy graduating in ’18. Jo wrote his master’s thesis, published as “Going beyond the Catch-22 of autism diagnosis and research”, on the moral implications of asking “What is autism?”. He is currently a PhD researcher in the ERC project NeuroEpigenEthics with a specific focus on Tourette’s.

“Variational tendencies: development as an ultimate cause”

ABSTRACT

The separation between ultimate and proximate causes is one of the most classical topics in the philosophy of biology. The ongoing debate over the Extension of the Evolutionary Synthesis (EES) includes a wide variety of philosophical topics, among which is a revision of such separation in the light of new evolutionary research agendas. In particular, it has been argued that some proximate causes, such as the development of organisms or their ecological interactions, play an evolutionary role in the sense that they are a necessary step in evolutionary transformations. While this has partially blurred the distinction between proximate and ultimate causes for local evolutionary changes, it has left relatively untouched the philosophical ideas about general tendencies in evolution, natural selection and chance remaining to be considered the main general driving evolutionary forces. Contrary to this view, in this paper I argue that the variational tendencies studied in evolutionary-developmental biology, or evo-devo, (evolvability, variability, modularity, robustness and plasticity) are ultimate causes in a sense that overcomes the specificities of local evolutionary changes. These properties, studied through genotype-phenotype maps, refer to structural features of how variation is produced in reproduction, and are increasingly being introduced in predictive models of evolution. I defend that these properties are better understood as propensities, analogous to how fitness and drift are usually seen in the philosophy of biology. While they are realized in particular developing systems, they refer to general features shared across taxa and affecting the production of variation in systematic ways, falling into the traditional category of ‘ultimate’ causes. I conclude with some ideas about how this consideration of variational tendencies can affect the notions of chance and contingency in evolution.

“Integrating entropy, constraints closure, and historicity to understand anthropogenic disruptions”

ABSTRACT

The term “disruption” is commonly used in the literature to describe anthropogenic damages on ecosystems and life cycles. However, this notion has not been conceptualized and theorized as such. Here we will focus on the specific case of plant-pollinators networks and their disruption by climate change. We will show that the analysis of these situations requires integrating constraints closure and historical reasoning. Moreover, entropy enters the picture in a new way: its coarse-graining is defined by constraints closure. This framework leads to an initial account of disruption in biology: disruption as a loss of historical singularity impacting constraints closure.

“Autoorganización como propiedad de nivel. Una visión reduccionista no eliminativista de la perspectiva organizacional” [The presentation will be in Spanish]

ABSTRACT:

El comportamiento de los sistemas complejos se ha abordado en muy diferentes disciplinas desde enfoques que apelan a la autoorganización como una propiedad clave de ciertas entidades. Una de las propuestas actuales más influyentes se basa en la idea de cierre organizacional, esto es, un tipo de organización característico de entidades como los seres vivos en el que puede identificarse un cierre de constricciones que da lugar a propiedades con poderes causales que determinan el automantenimiento. Estas propiedades son consideradas usualmente como emergentes. En este trabajo se defiende que,
aunque esta idea de cierre organizacional tiene una valiosa capacidad explicativa, no conlleva necesariamente la asunción de un emergentismo ontológico. Desde una perspectiva que parte de la noción de cuasi-descomponibilidad de Herbert Simon, en este trabajo se desarrolla una caracterización de la idea de cierre organizacional como principio explicativo compatible con una interpretación ontológica reduccionista, en tanto en cuanto no precisa de la postulación de propiedades emergentes, pero también epistemológicamente no eliminativista, pues entiende que la noción de cierre de constricciones tiene un irrenunciable valor heurístico para el discurso biológico.

IAS-Research Talk, Cristian Saborido’s (UNED) presentation of his book “Filosofía de la Medicina” (in Spanish)

On Tuesday 26 January 2021 at 11:30.

To participate, please contact guglielmo.militello@ehu.eus

ABSTRACT:

¿Qué es la salud? ¿Qué criterios se utilizan para identificar y clasificar las enfermedades? ¿De qué forma se debe conjugar la perspectiva de los médicos con la de los pacientes? ¿Existen realmente las enfermedades mentales? A la consciencia de que tenemos una naturaleza frágil le acompaña la esperanza de que podemos tomar medidas para combatir el sufrimiento y postergar la amenaza de la muerte. A lo largo de los siglos y en todas las culturas nos hemos esforzado por identificar, prevenir y tratar de revertir aquellos estados corporales que consideramos molestos o peligrosos, lo que ha dado lugar a esa particular síntesis de ciencia y arte a la que llamamos medicina. Con un lenguaje accesible y cercano, esta obra demuestra que la medicina es un objeto de estudio ineludible para la filosofía. A través de la descripción de casos médicos concretos, del recurso a ejemplos históricos, e incluso de la alusión a diferentes productos de la cultura popular como el arte, el cine o la televisión, se analizan críticamente las cuestiones que conforman la emergente filosofía de la medicina, al tiempo que se ofrecen herramientas conceptuales para comprender qué asunciones presupone y qué consecuencias implica la práctica médica.

IAS-Research talk (online), Matteo Mossio (CNRS & Université Paris 1 Panthéon-Sorbonne), “On why biological autonomy cannot live without closure”

Tuesday, the 15th of December 2020, 11:30 (Central European Time)

To participate, please contact: guglielmo.militello@ehu.eus

ABSTRACT:

In this talk, I examine the role of organizational closure within the theory of biological autonomy. Many authors, as Piaget, Maturana, Varela, Rosen and Kauffman in the 20th century, have elaborated on closure as a distinctive feature of biological systems, notably in connection with thermodynamic openness. In essence, my claim is that there is no biological autonomy without closure, for fundamental theoretical and philosophical reasons. Autonomy cannot live without closure. Yet, substantial work is still to be done to show how organizational closure can contribute to explain crucial  biological phenomena, many of which are addressed by the Outonomy project. I discuss in a preliminary way how closure can take up the challenge.

IAS-Research Talk (Online), Andrea Gambarotto (UC Louvain), “The Varieties of Kantian Teleology: A Contemporary Assessment”, 01/12/2020, 11:30

To participate, please contact: guglielmo.militello@ehu.eus

Abstract:

This paper addresses the ways in which Kant’s transcendental views concerning the intrinsic purposiveness of living organisms have been translated into naturalist territory by contemporary philosophy of biology. We critically evaluate the interpretive challenges posed by such endeavours and provide a tentative classification of the various approaches which have been proposed for applying Kant’s ideas today. We first delve into exegetical questions concerning the notions of mechanism and teleology, along with those of constitutive and regulative principles. We then distinguish three approaches to making Kant relevant today, each of which is characterized by a specific idea regarding what is useful about his perspective on teleology. We define those as heuristic, synthetic, and revisionist approaches respectively.

IAS-Research Talk (Online) by Laura Nuño de la Rosa’s (Complutense University of Madrid): “Interviews on evolvability: reconstructing and explaining the recent history of evolutionary biology”

Tuesday, 23/06/2020, at 11:30.

To participate, please contact: guglielmo.militello@ehu.eus

ABSTRACT:

In my presentation, I will present the results of a series of interviews to evolutionary biologists I have conducted throughout this academic year, in the frame of the project “Evolvability: a new and unifying concept in evolutionary biology”, which has taken place at the Center for Advanced Studies, Norwegian Academy of Arts and Letters. These interviews cover many different topics on theoretical debates and interdisciplinary relationships in evolutionary biology, but in this talk, I will focus on some insights I believe can be gained on the recent history of evolutionary theory. In particular, I will reflect on different causal hypotheses that might explain the explosion of the interest, in the mid-1990s, in the internal capacities of biological systems to evolve. In order to do so, I will use several conceptual tools from evolutionary theory itself that, as I hope to show, can be fruitfully applied to the history of science.
