Large sets of elements interacting locally and producing specific architectures reliably form a category that transcends the usual dividing line between biological and engineered systems. We propose to call them morphogenetically architected complex systems (MACS). While taking the emergence of properties seriously, the notion of MACS enables at the same time the design (or “meta-design”) of operational means that allow controlling and even, paradoxically, programming this emergence. To demonstrate our claim, we first show that among all the self-organized systems studied (...) in the field of Artificial Life, the specificity of MACS essentially lies in the close relation between their emergent properties and functional properties. Second, we argue that to be a MACS a system does not need to display more than weak emergent properties. Third, since the notion of weak emergence is based on the possibility of simulation, whether computational or mechanistic via machines, we see MACS as good candidates to help design artificial self-architected systems (such as robotic swarms) but also harness and redesign living ones (such as synthetic bacterial films).

"Descartes is rightly considered the father of modern philosophy" - Schopenhauer "The effect of this man on his age and the new age cannot be imagined broadly enough... René Descartes is indeed the true beginner of modern philosophy, insofar as it makes thinking the principle. "- Hegel "Descartes was the first to bring to light the idea of a transcendental science, which is to contain a system of knowledge of the conditions of possibility of all knowledge." - Kant A (...) new 2023 translation directly from the original manuscripts into English of Descartes' famous work "Rules for the Direction of the Mind" (Règles pour la direction de l'esprit). This edition contains a new introduction and afterword from the translator, as well as a timeline of Descartes' life and summaries of each of his works. Here, Descartes lays out a method for approaching problems and seeking knowledge. The importance of this work lies in the fact that it established the scientific method as a way of investigating the world, and had a significant influence on the development of modern science. This work is one of the foundational texts of Western Philosophy. (shrink)

First published in 1923 as part of the Cambridge Plain Texts series, this volume contains Descartes' Discours de la méthode in the original French. A short editorial introduction in English is also included. This book will be of value to anyone with an interest in the works of Descartes and the development of rationalism.

Richard Wollheim famously argued that figurative pictures depict their scenes, in part, in virtue of their ability to elicit a unique type of visual experience in their viewers, which he called seeing-in. According to Wollheim, experiences of seeing-in are necessarily twofold, that is, they involve two aspects of visual awareness: when a viewer sees a scene in a picture, she is simultaneously aware of certain visible features of the picture surface, the picture’s design, and the scene depicted by the picture. (...) Even though Wollheim’s notion of twofoldness has been very influential, a number of philosophers have put forward powerful arguments against it. In this paper, I defend the claim that some pictorial experiences are twofold in Wollheim’s sense. My argument has two parts. In the first part, I provide a phenomenal contrast argument in favor of twofoldness. In the second part, I respond to what I take to be the most important objections against twofoldness. I believe that both parts together provide strong support for the claim that some pictorial experiences are twofold in Wollheim’s sense. (shrink)

Les contributions réunies dans le présent recueil ont, pour la plupart, fait l’objet de communications à l’occasion de deux Journées d’étude organisées l’une à l’Université de Rouen Haute-Normandie par l’ « Équipe de recherche sur les aires culturelles » (ERIAC), l’autre à l’Université de Rennes I par « Philosophie des normes », respectivement les 23 et 25 janvier 2008. Leur ensemble ne donne pas une cartographie complète, même dans les grandes lignes, de la conception aristotélicienne de la rationalité sous ses (...) divers visages : la pratique scientifique d’Aristote et sa conception de la physique, par exemple, ne sont pas considérées ici, pas plus que la contribution décisive du Stagirite à l’histoire de la philosophie première, ontologie ou théologie. La forme achevée du recueil reflète l’esprit dans lequel ont été envisagées les deux Journées dans le prolongement desquelles il s’inscrit et lors desquelles ont été privilégiés les aspects publics et éthiques de la rationalité telle qu’a pu la concevoir celui qui, comme auteur dudit Organon et héritier de la dialectique socratique et platonicienne, est tout d’abord le fondateur de ce que nous appelons « logique », dont il envisage aussi, dans les Seconds analytiques, les prolongements scientifiques (didactiques et démonstratifs). L’ouvrage, qui traite à plusieurs reprises de l’influence d’Aristote, comporte ainsi trois sections : « De la dialectique à la science », « Art oratoire et poésie », « La rationalité éthique ». Ont été réunies, dans la première section, des contributions de Jean-Baptiste Gourinat (« Dialogue et dialectique : la place de la dialectique dans l’organon d’Aristote »), Pierre Joray (« Principe de contradiction et ecthèse dans la syllogistique d’Aristote »), Franck Varenne (« Le rapport entre science et logique chez Aristote vu à travers la critique de Dewey ») ; d’Annie Hourcade (« Le conseil dans la Rhétorique d’Aristote »), Jean-Pierre Cléro (« La Rhétorique d’Aristote et les penseurs des passions du xviiie siècle »), Michele Corradi (« Aristote et la réflexion de Protagoras sur les noms »), Maddalena Vallozza (« Entre poésie et histoire.

Après avoir lu les Méditations métaphysiques, la jeune Elisabeth de Bohême demande à s’entretenir avec Descartes pour obtenir des réponses. Ainsi naît, entre un philosophe déjà vieux et une princesse mélancolique, une conversation épistolaire qui durera sept ans, jusqu’à la mort de Descartes en 1650. Ils discuteront aussi bien de mathématiques et de géométrie que de l’union de l’âme et du corps, des passions, du bonheur et de Dieu. Sans jamais renier sa pensée – bien plutôt en la fortifiant –, (...) Descartes diagnostiquera à la jeune femme un excès de cartésianisme : pour la soigner, il valorisera les plaisirs de la vie courante, le repos de l’esprit et le manque de sérieux. Ce volume rassemble la correspondance intégrale entre Descartes et Elisabeth, ainsi que des lettres du philosophe à divers correspondants, dont le médecin Regius, Christine, reine de Suède, et Chanut, ambassadeur de France en Suède.

Dernier ouvrage publie par Descartes, le Traite des Passions de l'ame (1649) est le fruit de toute sa philosophie. Ce traite, qui s'appuie sur un resume de la biologie cartesienne, s'oriente vers une medecine concrete des affections psycho-physiologiques et s'epanouit en une apologie de la generosite. Aux observations scientifiques, Descartes ne dedaigne pas d'adjoindre des notations psychologiques dont la finesse evoque parfois ces maximes qui fleurissaient dans les salons au XVIIe siecle. Ainsi l'ampleur des conclusions scientifiques, morales et metaphysiques, sources (...) d'etudes toujours renaissantes pour les specialistes, se colore par surcroit d'une richesse vecue qui fait de ce Traite, ecrit pour une princesse et offert a une reine, le modele des ouvrages accessibles au plus grand public.

Which properties can we visually experience? Some authors hold that we can experience only low-level properties such as color, illumination, shape, spatial location, and motion. Others believe that we can also experience high-level properties, such as being a dog or being a pine tree. On the basis of her method of phenomenal contrast, Susanna Siegel has recently defended the latter view. One of her central claims is that we can best account for certain phenomenal contrasts if we assume that we (...) can visually experience natural kind properties. In this paper, I argue that certain kinds of low-level properties, namely shape-gestalt properties, can explain these phenomenal contrasts just as well as high-level properties. If successful, this is a modest, but nevertheless significant result. Even though it does not prove the falsity of Siegel’s proposal, it nevertheless secures the existence of a plausible alternative.

Attempts to interpret the manifold aspects of the ternary heaven, earth and man, drawing mainly on Far-Eastern sources. This study aims to demonstrate the metaphysical, cosmological and spiritual perspectives underlying the Triad symbol.

We investigate sequent calculi for the weak modal (propositional) system reduced to the equivalence rule and extensions of it up to the full Kripke system containing monotonicity, conjunction and necessitation rules. The calculi have cut elimination and we concentrate on the inversion of rules to give in each case an effective procedure which for every sequent either furnishes a proof or a finite countermodel of it. Applications to the cardinality of countermodels, the inversion of rules and the derivability of Löb (...) rules are given. (shrink)

Our lives are increasingly intertwined with the digital realm, and with new technology, new ethical problems emerge. The academic field that addresses these problems—which we tentatively call ‘digital ethics’—can be an important intellectual resource for policy making and regulation. This is why it is important to understand how the new ethical challenges of a digital society are being met by academic research. We have undertaken a scientometric analysis to arrive at a better understanding of the nature, scope and dynamics of (...) the field of digital ethics. Our approach in this paper shows how the field of digital ethics is distributed over various academic disciplines. By first having experts select a collection of keywords central to digital ethics, we have generated a dataset of articles discussing these issues. This approach allows us to generate a scientometric visualisation of the field of digital ethics, without being constrained by any preconceived definitions of academic disciplines. We have first of all found that the number of publications pertaining to digital ethics is exponentially increasing. We furthermore established that whereas one may expect digital ethics to be a species of ethics, we in fact found that the various questions pertaining to digital ethics are predominantly being discussed in computer science, law and biomedical science. It is in these fields, more than in the independent field of ethics, that ethical discourse is being developed around concrete and often technical issues. Moreover, it appears that some important ethical values are very prominent in one field (e.g., autonomy in medical science), while being almost absent in others. We conclude that to get a thorough understanding of, and grip on, all the hard ethical questions of a digital society, ethicists, policy makers and legal scholars will need to familiarize themselves with the concrete and practical work that is being done across a range of different scientific fields to deal with these questions.

Authentique zoologue, Aristote fait de l’homme un animal parmi d’autres au sein des êtres naturels. Les travaux scientifiques, cependant, malgré des rapprochements, mettent déjà en évidence sa singularité, tandis que l’animal non humain, considéré comme dépourvu de raison malgré des nuances, est exclu du champ de l’éthique dont la bestialité marque la limite. La vertu se conquiert en grande partie contre la part animale de l’homme mais l’animal en est incapable au sens strict. L’animal n’a guère valeur de modèle et (...) la lecture d’Aristote fournit peu d’arguments immédiatement exploitables en faveur de sa protection. (shrink)

In this reproduction of his original publication of 1649, Rene Descartes discusses how seekers of knowledge can best attain true insight of the world around them. Often referred to as simply the Discourse on the Method, this work is frequently cited as one of the most important to appear during the Enlightenment era. It discusses the ideal means through which those in search of knowledge can approach the world, and the practice of science, as a means of attaining true and (...) definitive insight. The Discourse on Method is influential chiefly for its role in establishing the scientific method; a technique which scientists have used to make valid discoveries over the centuries. Descartes instructs the reader to doubt everything, and to use this universal doubt as a starting point from which to approach a problem. In addition to matters of science, Descartes reflects upon his own personal, religious beliefs. In addition to his Method, Descartes also explains certain social and personal notions such as obeying the laws and statutes of his country and prioritizing self-advancement over the achievement of material wealth or fortune. Famous for including the much-quoted phrase "Je pense, donc je suis" - "I think, therefore I am" - the Discourse on Method today stands as a crucial cornerstone of countless educational courses on philosophy.

Rene Descartes has been described as the "father" of modern philosophy. This selection of Descartes' writings attempt to answer central questions surrounding self, God, free-will and knowledge, using the science of thought as opposed to received wisdom based on the tenets of faith.

Paintings can exert a strong effect on their viewers by creating atmospheres. But how is it possible for a painting to create an atmosphere? My goal in this paper is to provide a partial answer to this question by focusing on the depiction of light. I argue that paintings can elicit experiences of atmospheres in part because they can depict pictorial space as filled with ambient light that has a distinctive phenomenal character. It is in virtue of this distinctive phenomenal (...) character that the depicted ambient light can make a significant contribution to the overall phenomenal character of the experienced atmosphere.

In his paper “Double Vision, Phosphenes and Afterimages: Non-Endorsed Representations rather than Non-Representational Qualia,” Işık Sarıhan addresses the debate between strong representationalists and qualia theorists. He argues that qualia theorists like Ned Block and Amy Kind who cite double-vision, afterimages, etc., as evidence for the existence of qualia are mistaken about the actual nature of these states. According to Sarıhan, these authors confuse the fact that these states are non-endorsed representational states with the fact that they are at least partly (...) non-representational. I argue that Sarıhan’s argument contains gaps that suggest that he misidentifi es the mistake that leads these qualia theorists to their conclusion. In my view, these qualia theorists do not confuse the fact that the states in question are non-endorsed states with the fact that they are non-representational, but rather mistake certain representational contents, or certain aspects of these contents, for qualia.

Aristote fait parfois état d’une pensée animale. Dans le De motu animalium, il paraît même considérer que les animaux ont recours à des syllogismes pratiques : il vaut cependant mieux résister à toute tentation de croire qu’il explique en ces termes le comportement animal, dans la mesure où il refuse d’attribuer aux animaux non humains le raisonnement, et tout d’abord l’universalité de la pensée ; or, qui dit absence de concepts ou de jugements universels dit incapacité d’établir les prémisses d’un (...) syllogisme.

El presente artículo se enfrenta al problema clásico sobre cómo interpretar lo que Aristóteles, en de An. III, 5, denomina “el intelecto que produce todas las cosas”, llamado comúnmente intelecto agente. Históricamente, se han presentado dos lecturas: una, que se remonta a Alejandro de Afrodisia, que lo asocia con el motor inmóvil y con la divinidad y otra, asociada a Teofrasto pero que tiene en Filópono y St. Tomás de Aquino a sus principales representantes, que lo considera una facultad puramente (...) humana. Esta última interpretación ha sido históricamente la más sostenida; sin embargo, en tiempos recientes ha habido un resurgimiento de interpretaciones del intelecto agente como “divino”. Lo que queremos mostrar en este texto es que este resurgimiento se debe, más que a una reinterpretación del intelecto agente, a una comprensión diferente de la divinidad en la filosofía aristotélica, con características inmanentes y más próximas al intelecto humano.

The hexagonal structure for ‘the geometry of logical opposition’, as coming from Aristoteles–Apuleius square and Sesmat–Blanché hexagon, is presented here in connection with, on the one hand, geometrical ideas on duality on triangles (construction of ‘companion’), and on the other hand, constructions of tripartitions, emphasizing that these are exactly cases of borromean objects. Then a new case of a logical interest introduced here is the double magic tripartition determining the semi-ring ${\mathcal{B}_3}$ and this is a borromean object again, in the (...) heart of the semi-ring ${{\rm Mat}_{3}(\mathbb{B}_{\rm Alg})}$ . With this example we understand better in which sense the borromean object is a deepening of the hexagon, in a logical vein. Then, and this is our main objective here, the Post-Mal’cev full iterative algebra ${\mathbb{P}_4 = \mathbb{P}(\mathbb{F}_4)}$ of functions of all arities on ${\mathbb{F}_4}$ , is proved to be a borromean object, generated by three copies of ${\mathbb{P}_2}$ in it. This fact is induced by a hexagonal structure of the field ${\mathbb{F}_4}$ . This hexagonal structure is seen as precisely a geometrical addition to standard boolean logic, exhibiting ${\mathbb{F}_4}$ as a ‘boolean manifold’. This structure allows to analyze also ${\mathbb{P}_4}$ as generated by adding to a boolean set of logical functions a very special modality, namely the Frobenius squaring map in ${\mathbb{F}_4}$ . It is related to the splitting of paradoxes, to modified logic, to specular logic. It is a setting for a theory of paradoxical sentences, seen as computations of movements on the bi-hexagonal link among the 12 classical logics on a set of 4 values. (shrink)

A common view in the philosophy of perception holds that states of seeing objects face to face have particular contents. When you see, say, a dog face to face, your visual state represents the particular dog that is in front of you. In this paper, I argue for a related claim about states of seeing objects in conventional photographs. When you see a dog in a photograph, for example, your visual state represents the particular dog that was in front of (...) the camera when the photograph was taken, that is, the photograph's depictum. The argument in this paper proceeds in two steps. In the first step, I discuss states of seeing objects face to face. I argue that such a state represents the particular object whose surface is responsible for the optical information that the visual system uses to construct the state's attributive representational content. In the second step, I apply the result of this discussion to states of seeing objects in photographs. I argue that a state of seeing an object in a photograph has a particular content that represents the object that was in front of the camera when the photograph was taken. (shrink)

The genetic analysis of development has revealed the importance of small sets of interacting genes in most morphogenetic processes. The results of gene interactions have so far been examined intuitively. This approach is largely sufficient when one deals with simple interactions, a feedback circuit for example. As more components become involved, however, it is difficult to make sure that the intuitive approach gives a comprehensive view of the behaviour of the system. In this paper, we illustrate the use of a (...) logical approach to describe the genetic circuit that underlies the singling out of sense organ precursor cells in Drosophila. We show how to apply logical modelling to a realistic problem, and how this approach allows an easy assessment of the dynamic properties of the system, i.e., of its possible evolutions and of its reactions to fluctuations and perturbations.
