The Return of Vitalism: Canguilhem and French Biophilosophy in the 1960S
The Return of Vitalism: Canguilhem and French Biophilosophy in the 1960s Charles T. Wolfe Unit for History and Philosophy of Science University of Sydney [email protected] Abstract The eminent French biologist and historian of biology, François Jacob, once notoriously declared ―On n‘interroge plus la vie dans les laboratoires‖1: laboratory research no longer inquires into the notion of ‗Life‘. Nowadays, as David Hull puts it, ―both scientists and philosophers take ontological reduction for granted… Organisms are ‗nothing but‘ atoms, and that is that.‖2 In the mid-twentieth century, from the immediate post-war period to the late 1960s, French philosophers of science such as Georges Canguilhem, Raymond Ruyer and Gilbert Simondon returned to Jacob‘s statement with an odd kind of pathos: they were determined to reverse course. Not by imposing a different kind of research program in laboratories, but by an unusual combination of historical and philosophical inquiry into the foundations of the life sciences (particularly medicine, physiology and the cluster of activities that were termed ‗biology‘ in the early 1800s). Even in as straightforwardly scholarly a work as La formation du concept de réflexe aux XVIIe et XVIIIe siècles (1955), Canguilhem speaks oddly of ―defending vitalist biology,‖ and declares that Life cannot be grasped by logic (or at least, ―la vie déconcerte la logique‖). Was all this historical and philosophical work merely a reassertion of ‗mysterian‘, magical vitalism? In order to answer this question we need to achieve some perspective on Canguilhem‘s ‗vitalism‘, notably with respect to its philosophical influences such as Kurt Goldstein. -

Opinion - Paper under review Deep Learning and the Global Workspace Theory Rufin VanRullen1, 2 and Ryota Kanai3 1CerCo, CNRS UMR5549, Toulouse, France 2ANITI, Universit´ede Toulouse, France 3Araya Inc, Tokyo. Japan Abstract Recent advances in deep learning have allowed Artificial Intelligence (AI) to reach near human-level performance in many sensory, perceptual, linguistic or cognitive tasks. There is a growing need, however, for novel, brain-inspired cognitive architectures. The Global Workspace theory refers to a large-scale system integrating and distributing infor- mation among networks of specialized modules to create higher-level forms of cognition and awareness. We argue that the time is ripe to consider explicit implementations of this theory using deep learning techniques. We propose a roadmap based on unsu- pervised neural translation between multiple latent spaces (neural networks trained for distinct tasks, on distinct sensory inputs and/or modalities) to create a unique, amodal global latent workspace (GLW). Potential functional advantages of GLW are reviewed, along with neuroscientific implications. 1 Cognitive neural architectures in brains and ma- chines Deep learning denotes a machine learning system using artificial neural networks with multiple \hidden" layers between the input and output layers. Although the underlying theory is more than 3 decades old [1, 2], it is only in the last decade that these systems have started to fully reveal their potential [3]. Many of the recent breakthroughs in AI (Artificial Intelligence) have been fueled by deep learning. Neuroscientists have been quick to point out the similarities (and differences) between the brain and these deep artificial neural networks [4{9]. The advent of deep learning has allowed the efficient computer implementation of perceptual and cognitive functions that had been so far arXiv:2012.10390v2 [cs.AI] 20 Feb 2021 inaccessible. -
Dennett's Theory of the Folk Theory of Consciousness
Dennett’s Theory of the Folk Theory of Consciousness1 Justin Sytsma Abstract: It is not uncommon to find assumptions being made about folk psychology in the discussions of phenomenal consciousness in philosophy of mind. In this article I consider one example, focusing on what Dan Dennett says about the “folk theory of consciousness.” I show that he holds that the folk believe that qualities like colors that we are acquainted with in ordinary perception are phenomenal qualities. Nonetheless, the shape of the folk theory is an empirical matter and in the absence of empirical investigation there is ample room for doubt. Fortunately, experimental evidence on the topic is now being produced by experimental philosophers and psychologists. This article contributes to this growing literature, presenting the results of six new studies on the folk view of colors and pains. I argue that the results indicate against Dennett’s theory of the folk theory of consciousness. The existence of phenomenal consciousness is often taken for granted in the philosophical and scientific literature on the topic. Sometimes, this attitude is supported by claims that phenomenal consciousness is in some way evident in our ordinary experience itself.2 The prevalence of this attitude can also be seen in the way that some skeptics about phenomenal consciousness discuss the supposed phenomenon. For example, the qualia eliminativist Dan Dennett seems to accept that belief in qualia is part of our “folk theory of consciousness” (2005, 31). In contrast, I have argued that phenomenal consciousness is not evident in ordinary experience alone—that it is not phenomenologically obvious—and that this can be drawn out by 1 To appear in the Journal of Consciousness Studies. -

On the one hand, the belief that nonhuman animals suffer and feel pain is what draws many people to want to study animal welfare in the first place. Animal welfare is seen as fundamentally different from plant “welfare” or the welfare of works of art precisely because of the widely held belief that animals have feelings and experience emotions in ways that plants or inanimate objectsdhowever valuableddo not (Midgley, 1983; Regan, 1984; Rollin, 1989; Singer, 1975). On the other hand, consciousness is also the most elusive and difficult to study of any biological phenomenon (Blackmore, 2012; Koch, 2004). Even with our own human consciousness, we are still baffled as to how Advances in the Study of Behavior, Volume 47 ISSN 0065-3454 © 2014 Elsevier Inc. -
Vitalism and the Scientific Image: an Introduction
Vitalism and the scientific image: an introduction Sebastian Normandin and Charles T. Wolfe Vitalism and the scientific image in post-Enlightenment life science, 1800-2010 Edited by Sebastian Normandin and Charles T. Wolfe Springer, forthcoming 2013 To undertake a history of vitalism at this stage in the development of the ‘biosciences’, theoretical and other, is a stimulating prospect. We have entered the age of ‘synthetic’ life, and our newfound capacities prompt us to consider new levels of analysis and understanding. At the same time, it is possible to detect a growing level of interest in vitalistic and organismic themes, understood in a broadly naturalistic context and approached, not so much from broader cultural concerns as in the early twentieth century, as from scientific interests – or interests lying at the boundaries or liminal spaces of what counts as ‘science’.1 The challenge of understanding or theorizing vitalism in the era of the synthetic is not unlike that posed by early nineteenth-century successes in chemistry allowing for the synthesis of organic compounds (Wöhler), except that now, whether the motivation is molecular-chemical, embryological or physiological,2 we find ourselves asking fundamental questions anew. What is life? How does it differ from non-living matter? What are the fundamental processes that characterize the living? What philosophical and epistemological considerations are raised by our new understandings?3 We are driven to consider, for example, what metaphors we use to describe living processes as our knowledge of them changes, not least since some of the opprobrium surrounding the term ‘vitalism’ is also a matter of language: of which terms one 1 Gilbert and Sarkar 2000, Laublichler 2000. -
Abstract: This Paper Argues Against Daniel Dennett's Conception of What
Abstract: This paper argues against Daniel Dennett’s conception of what is labeled as the Intentional Stance. Daniel Dennett thinks that conceiving of human beings, as Intentional Systems will reveal aspects about human action that a physical examination of the composition of their bodies will always fail to capture. I will argue against this claim by a reexamination of the Martian’s thought experiment. I will also analyze Dennett’s response to the famous Knowledge argument in order to point out a seeming contradiction in his view which will make my point stronger. Lastly, I will try to conclude with general remarks about my own view. Due to numerous advancements in the field of neurology, philosophers are now reconsidering their views on mental states. This in turn led to reconsideration of common views on action and intentionality in contemporary philosophy. In this paper I will try to defend a strict version of the Physicalist view of human nature, which states that everything about human action and intentionality can be explained by the study of physical matter, physical laws and physical history of humans. This will be attained by exploring the contrast between Daniel Dennett’s Intentional and Physical stances, and by showing how the former “fails” in face of the latter (contra Dennett), especially when considering the evolution of the human species. After that, I will try to point out an inconsistency in Dennett’s view especially in his dealing with Frank Jackson’s Knowledge Argument. I will end with a brief conclusion about the view I am advocating. A central claim of Dennett’s thesis is that if a system holds true beliefs and could be assigned beliefs and desires, then, given the proper amount of practical reasoning, that system’s actions should be relatively accurately predicted, and we can say, then, that the system is an intentional system to whom we can apply the intentional stance. -

Indeed, there are many definitions of consciousness and multiple approaches to study the neural correlates of consciousness (NCC). Therefore, the main aim of this article is to collect data on the various theories of consciousness published between 2007–2017 and to synthesize them to provide a general overview of this topic. To describe each theory, we developed a thematic grid called the dimensional model, which qualitatively and quantitatively analyzes how each article, related to one specific theory, debates/analyzes a specific issue. -
Consciousness, Philosophical Issues About Ned Block New York University I
To appear in The Encyclopedia of Cognitive Science Consciousness, Philosophical Issues about Ned Block New York University I. The Hard Problem There are a number of different matters that come under the heading of ‘consciousness’. One of them is phenomenality, the feeling of say a sensation of red or a pain, that is what it is like to have such a sensation or other experience. Another is reflection on phenomenality. Imagine two infants, both of which have pain, but only one of which has a thought about that pain. Both would have phenomenal states, but only the latter would have a state of reflexive consciousness. This entry will start with phenomenality, moving later to reflexivity and then to one other kind of consciousness. The Hard Problem of consciousness is how to explain a state of consciousness in terms of its neurological basis. If neural state N is the neural basis of the sensation of red, why is N the basis of that experience rather than some other experience or none at all? Chalmers (1996) distinguishes between the Hard Problem and “easy” problems that concern the function of consciousness. The Hard Problem (though not under that name) was identified by Nagel (1974) and further analyzed in Levine (1983). There are two reasons for thinking that the Hard Problem has no solution. 1. Actual Failure. In fact, no one has been able to think of even a highly speculative answer. 2. Principled Failure. The materials we have available seem ill suited to providing an answer. As Nagel says, an answer to this question would seem to require an objective account that necessarily leaves out the subjectivity of what it is trying to explain. -

A Dangerous Idea Dennett considers Darwin’s theory of evolution by natural selection the best single idea that anyone ever had.But it has also turned out to be a dangerous one. Science has accepted the theory as the most accurate explanation of the intricate design of living beings,but when it was first proposed,and again in recent times,the theory has met with a backlash from many people.What makes evolution so threatening,when theories in physics and chemistry seem so harmless? One problem with the introduction of Darwin’s great idea is that almost no one was prepared for such a revolutionary view of creation. Dennett gives an analogy between this inversion and Sweden’s change in driving direction: I’m going to imagine, would it be dangerous if tomorrow the people in Great Britain started driving on the right? It would be a really dangerous place to be because they’ve been driving on the left all these years…. -

Global Workspace Theory and Animal Consciousness
19 August 2020 Global Workspace Theory and Animal Consciousness Jonathan Birch Centre for Philosophy of Natural and Social Science, London School of Economics and Political Science, Houghton Street, London, WC2A 2AE, UK. Email: [email protected] Webpage: http://personal.lse.ac.uk/birchj1 This is a preprint of an article that will appear in Philosophical Topics. 7082 words 1 Abstract: Carruthers has recently argued for a surprising conditional: if a global workspace theory of phenomenal consciousness is both correct and fully reductive, then there are no substantive facts to discover about phenomenal consciousness in non-human animals. I present two problems for this conditional. First, it rests on an odd double-standard about the ordinary concept of phenomenal consciousness: its intuitive non-gradability is taken to be unchallengeable by future scientific developments, whereas its intuitive determinacy is predicted to fall by the wayside. Second, it relies on dismissing, prematurely, the live empirical possibility that phenomenal consciousness may be linked to a core global broadcast mechanism that is (determinately) shared by a wide range of animals. Future developments in the science of consciousness may lead us to reconsider the non-gradability of phenomenal consciousness, but they are unlikely to lead us to accept that there are no facts to discover outside the paradigm case of a healthy adult human. Key words: animal consciousness, phenomenal consciousness, consciousness science, global workspace theory, phenomenal concepts 2 1. Carruthers’ surprising conditional For more than thirty years, scepticism about attributions of phenomenal consciousness1 to (states of) non-human animals has been a major theme in Peter Carruthers’ work (Carruthers 1989, 1992, 1999, 2000, 2004, 2005, 2018a,b, 2019, 2020).
