Artists and designers working in the fields of generative and bio art frequently focus on designing speculative visions of how nature can be reimagined with the use of computational media and synthetic biology. Centered on the unique artistic strategies of reimagining life forms, this paper analyzes and compares a selection of generative software-based projects, in which artists are mimicking different natural phenomena and have the tendency to beautify nature and life, with bio art projects, where ethical considerations are prioritized over (...) other aspects of the work. Experimenting with software and producing code-based generative art can be a relatively accessible creative endeavor while working with synthetic biology requires more demanding and controlled workplace conditions and specialized equipment. Despite the differences in accessibility and usability, both fields of generative and bio art challenge the boundaries of contemporary artistic practice and research by mapping, provoking and contemplating the dramatic changes of life forms, in the era when living matter can be re-engineered into a new material capable of computing.

In this article, we trace the analogies, parallels and affinities between bio-inspired generative art and bio art practices with strong generative flavour. We look at the creative and expressive features in these two fields, compare their shared interests in the design and development of life, and discuss the strategies they apply to communicate and engage the audience. With respect to the existing literature, which relates bio and generative art primarily within a historical context, we compare these two fields focusing on (...) generativity as their common poetic driver. We indicate their shared impetus for rendering distinctive visions of nature in order to identify, contemplate or provoke dramatic changes in the era when biological processes become programmable and living matter can be instrumentalized for various forms of labour. We also examine the epistemological and practical effectiveness of the two fields within a broader socio-technical perspective, which leads us to their constructive critique. (shrink)

This article defends the view that liars need not intend to deceive. I present common objections to this view in detail and then propose a case of a liar who can lie but who cannot deceive in any relevant sense. I then modify this case to get a situation in which this person lies intending to tell his hearer the truth and he does this by way of getting the hearer to recognize his intention to tell the truth by lying. (...) This case, and further cases that I develop from it, demonstrate that lying without the intention to deceive is possible. (shrink)

We conducted two experiments to determine whether common folk think that so-called _tell-tale sign_ bald-faced lies are intended to deceive—since they have not been tested before. These lies involve tell-tale signs (e.g. blushing) that show that the speaker is lying. Our study was designed to avoid problems earlier studies raise (these studies focus on a kind of bald-faced lie in which supposedly everyone knows that what the speaker says is false). Our main hypothesis was that the participants will think that (...) the protagonists from our examples lied without intending to deceive, and the results of our surveys confirmed this hypothesis: most of our participants rated tell-tale sign lies as lies not intended to deceive. Therefore, our analysis suggests that common folk think that some lies are not intended to deceive. (shrink)

Arguably, the existence of bald-faced (i.e. knowingly undisguised) lies entails that not all lies are intended to deceive. Two kinds of bald-faced lies exist in the literature: those based on some common knowledge that implies that you are lying and those that involve tell-tale signs (e.g. blushing) that show that you are lying. I designed the tell-tale sign bald-faced lies to avoid objections raised against the common knowledge bald-faced lies but I now see that they are more problematic than what (...) I initially thought. Therefore, I will discuss these lies in more detail, refine the existing cases, and resolve some anticipated objections. I conclude that tell-tale sign bald-faced lies are genuine lies not intended to deceive. (shrink)

According to one influential argument put forward by, e.g. Chisholm and Feehan, Pfister, Meibauer, Dynel, Keiser, and Harris, asserting requires intending to give your hearer a reason to believe what you say (first premise) and, because liars must assert what they believe is false (second premise), liars necessarily intend to cause their hearer to believe as true what the liars believe is false (conclusion). According to this argument, that is, all genuine lies are intended to deceive. ‘Lies’ not intended to (...) deceive are not genuine lies because they do not involve assertions and you need to assert in order to lie. In this paper, I reject this argument by arguing that the first premise is false: intending to give your hearer a reason to believe what you say is not necessary for asserting. (shrink)

In his 2018 AJP paper, Shlomo Cohen hints that deception could be a distinct subset of manipulation. We pursue this thought further, but by arguing that Cohen’s accounts of deception and manipulation are incorrect. Deception under uncertainty need not involve adding false premises to the victim’s reasoning but it must involve manipulating her response, and cases of manipulation that do not interfere with the victim’s reasoning, but rather utilize it, also exist. Therefore, deception under uncertainty must be constituted by covert (...) manipulation. (shrink)

Exegetical scepticism is a strand of scepticism about meaning running through the German Enlightenment. This paper provides the first modern account of its tenets, critics, and proponents, and argues that it shares essential features with modern varieties of meaning-scepticism that have been a preoccupation among philosophers of language since the middle of the twentieth century. I argue that exegetical scepticism is a type of epistemological scepticism first introduced as a philosophical position in a theological debate between August Pfeiffer (1640–1698) and (...) Philipp Jacob Spener (1635–1705). Under contention, so I argue, was the idea that interpretation is never certain because it is necessarily underdetermined by the evidence. Following the effects of this controversy, I show that exegetical scepticism caused a great deal of unrest in German letters in the eighteenth century and can be seen to contribute to the great proliferation of hermeneutical theories in the Aufklärung, indeed to the very birth of hermeneutics as a standalone discipline. Bringing this type of scepticism to contemporary attention supports a reassessment of issues at the heart of meaning-scepticism and hermeneutics itself, and a reconsideration of the histories of Enlightenment scepticism and hermeneutics.

Felix Klein and Abraham Fraenkel each formulated a criterion for a theory of infinitesimals to be successful, in terms of the feasibility of implementation of the Mean Value Theorem. We explore the evolution of the idea over the past century, and the role of Abraham Robinson's framework therein.

L'oeuvre de Vladimir Jankélévitch mêle intimement philosophie et musique, régime de correspondance auquel le philosophe-musicien a toujours aimé se tenir. " La musique, rappelle-t-il, est un art temporel non point secondairement, comme la poésie, le roman ou le théâtre, mais essentiellement. " Son domaine est la " temporalité enchantée ", le mystère de l'instant, le charme de la nostalgie, du nocturne et des parfums de la nuit, du lointain, du silence surtout, puisque la musique, née du silence, y retourne. (...) Ce livre réunit des textes peu connus, inédits ou depuis longtemps inaccessibles. Comptes rendus de concerts et de festivals, évocations poétiques des musiciens chers à son coeur : les musiciens français, particulièrement Debussy, Ravel, Fauré ; les musiciens de l'Europe centrale, Chopin et Liszt, le rhapsode et baladin du monde européen, image même de notre modernité ; les génies de la musique russe, notamment Moussorgski et Rimski-Korsakov. Pour Vladimir Jankélévitch " on ne pense pas la musique ", mais on peut penser en musique, ou musicalement. Le lecteur retrouvera dans ces textes le bonheur de la mystérieuse connivence d'une pensée sur la musique qui donne à entendre musicalement. (shrink)

This paper argues that extant signalling-based analyses cannot explain a range of cases of biological (and psychological) deception, such as those in which the deceiver does not send a signal at all, but that Artiga and Paternotte’s (Philos Stud 175:579–600, 2018) functional and my (Krstić in The analysis of self-deception: rehabilitating the traditionalist account. PhD Dissertation, University of Auckland, 2018: §3; Krstić and Saville in Australas J Philos 97:830–835, 2019) manipulativist analyses can. Therefore, the latter views should be given preference. (...) And because we still do not have a satisfactory definition of manipulation, the functional analysis, according to which a state is deceptive iff its function is to mislead and it misleads, is currently our best theory of deception. This is not to argue that the signalling-based analyses have no value but only that they should not be used in general analyses of biological deception. We need to move on to some other interesting issues. (shrink)

Several attempts have recently been made to point to ‘the proper place’ for hydrogen in the Periodic Table of the elements. There are altogether five different types of arguments that lead to the following conclusions: hydrogen should be placed in group 1, above lithium; hydrogen should be placed in group 17, above fluorine; hydrogen is to be placed in group 14, above carbon; hydrogen should be positioned above both lithium and fluorine and hydrogen should be treated as a stand-alone element, (...) in the center of the Periodic Table. Although all proposals are based on arguments, not all of them sound equally convincing. An attempt is made, after critical reexamination of the arguments offered, to hopefully point to the best possible choice for the position of hydrogen. A few words are also mentioned on the structure of the Periodic Table and the attempts to reorganize it. (shrink)

El presente artículo es el resultado de un proceso de investigación originado en la Maestría en Publicidad de la UTL, en la línea de Semiótica Publicitaria, dirigida por el profesor Vladimir Sánchez, quien en su seminario, ha venido construyendo un equipo de trabajo con los maestrantes en torno a la aplicabilidad de algunos de los postulados de la pragmática de Charles Sanders Peirce al campo publicitario. Los maestrantes Jairo Sojo y Juan José Arango, adelantaron algunas hipótesis sobre el trabajo (...) del profesor Sánchez, y, gracias a ello, se propuso a la UJTL y a la Universidad Santo Tomás, un proyecto interinstitucional de investigación titulado “Semiótica, planeación y estrategia publicitaria y de diseño. Proyecciones del Pragmatismo a la comunicación contemporánea”. En el marco de la investigación anteriormente mencionada, surge el artículo que aquí se presenta, como un primer planteamiento de las hipótesis de investigación que dan origen a dicho proceso y que pueden esbozarse en tres grandes aspectos. El primero, unas consideraciones generales sobre el pragmatismo desde una perspectiva publicitaria con énfais en la regla de cualificación planteada por Peirce en 1903. El segundo, la propuesta de un modelo de análisis de piezas publicitarias desde la operacionilización de la regla de cualificación. El tercero una modelación para la planeación de estrategias publicitarias a través de la regla de cualificación aplicada al cruce de los interpretantes ontológicos y los interpretantes modales.

The small, the tiny, and the infinitesimal have been the object of both fascination and vilification for millenia. One of the most vitriolic reviews in mathematics was that written by Errett Bishop about Keisler’s book Elementary Calculus: an Infinitesimal Approach. In this skit we investigate both the argument itself, and some of its roots in Bishop George Berkeley’s criticism of Leibnizian and Newtonian Calculus. We also explore some of the consequences to students for whom the infinitesimal approach is congenial. The (...) casual mathematical reader may be satisfied to read the text of the five act play, whereas the others may wish to delve into the 130 footnotes, some of which contain elucidation of the mathematics or comments on the history.

In the current philosophical literature, determinism is rarely defined explicitly. This paper attempts to show that there are in fact many forms of determinism, most of which are familiar, and that these can be differentiated according to their particular components. Recognizing the composite character of determinism is thus central to demarcating its various forms.

As a social activity, the sciences are only possible through communication among scientists themselves and between scientists and society. The article analyses natural, biological, social and ideological prerequisites of scientific communication (SC) as an ensemble of interrelated acts of scientific information exchange. A taxonomy of professional networks as a medium for SC is proposed. The need for a permanent struggle for the preservation and development of the values of both a free society and science is emphasized.

This is an expository article about the solution to the frame problem proposed in 1980 by Raymond Reiter. For years, his “frame default” remained untested and suspect. But developments in some seemingly unrelated areas of computer science—logic programming and satisfiability solvers—eventually exonerated the frame default and turned it into a basis for important applications.

The parameter-free part \(\textbf{PA}_2^*\) of \(\textbf{PA}_2\), second order Peano arithmetic, is considered. We make use of a product/iterated Sacks forcing to define an \(\omega \) -model of \(\textbf{PA}_2^*+ \textbf{CA}(\Sigma ^1_2)\), in which an example of the full Comprehension schema \(\textbf{CA}\) fails. Using Cohen’s forcing, we also define an \(\omega \) -model of \(\textbf{PA}_2^*\), in which not every set has its complement, and hence the full \(\textbf{CA}\) fails in a rather elementary way.

The work tends to point out the deficiency of some opinions claiming simplified presentation of the promise as the act that directly rise obligation for the promisor. Promises, either in the moral or legal sphere, are based on communication and so form an order of dependent steps that indicates their procedural nature. These characteristics may differ to a lesser extent, depending on the legal systems, moral norms of the society and its technical level and its needs. In all these cases, (...) however, the procedural characteristics of promises, especially in conditional promises, as well as the promises in contractual relations, persists. In our analysis we wish to show that the consistent conception of promise has to take into account a step of acceptance. The outcome of this approach relativizes a strong distinction between promise and offer. (shrink)

An application of diagrams for separating modes of theory development.

The sum of all objects of a science, the objects’ features and their mutual relations compose the reality described by that sense. The reality described by mathematics consists of objects such as sets, functions, algebraic structures, etc. Generally speaking, the use of terms reality and existence, in relation to describing various objects’ characteristics, usually implies an employment of physical and perceptible attributes. This is not the case in mathematics. Its reality and the existence of its objects, leaving aside its application, (...) are completely virtual and yet clearly organized. This organization can be recognized in the creation of axioms or in the arrival at new theorems and definitions. It results either from a formalization of an intuitive idea or from a combinatorics that has not been guided by intuition. In all four possible cases—therefore, also in the two in which there is no intuitive “lead”, we can plausibly talk about a discovery of mathematical facts and thus support the Platonist view.

In the target article, Sagvolden and collaborators propose that attentional-deficit/hyperactivity disorder (ADHD) is the result of a general behavioral deficit which is mainly caused by a hypofunctioning mesolimbic dopaminergic system. Although we partly agree with this view, we think that it tends to overlook the dysfunction of prefrontal and frontostriatal executive functions by considering them to be a consequence of alterations in reward and extinction mechanisms. Rather, we believe that ADHD is the result of an overall cognitive and behavioral condition, (...) associated to a generalized dopaminergic network dysfunction, and may not be easily attributable to a single basic behavioral function.

The keynote idea of the theses is contained in the author’s assumption that modern philosophy doesn’t meet its claiming pretensions: to be universal form of knowledge. First of all philosophy is connected not with knowledge but with ideas and secondly being authentic it “exists only in everyday life”.1 In orderthat philosophy could realize its innate essence corresponding conditions of social being should exist but they are still absent and therefore philosophy is absent as well. Its place is occupied by metaphysics (...) which is free movement of thinking that has no definiteness as the condition of being of any form of thought. That iswhy we watch crisis state of “philosophy” which becomes apparent in vagueness of its subject: “philosophy is not only one, there are many of them”. The author supposes that philosophy as the highest relation of mankind to objective reality is the only one. Philosophy lowered down from the heaven (Platon, Ciceron) in the field of human being must raise people not only to purity of thought, but mainly to purity of their activity both with each other and with nature. Then real interaction of men and nature will take place. This will be the beginning of spiritualization of the Universe. It may exist only under the conditions of social uniformity as historical form of Weltanschauung (world outlook) that removes religious form. Realization of its being supposes fundamental change of social life. It is necessary that private property should be replaced with social property in the sphere of social production. Only under these conditions philosophy may appear and exist as historical form of Weltanschauung. (shrink)

Traditionalists affirm that in self-deception I intend to deceive myself; but, on the standard account of interpersonal deception, according to which deceiver intend to make their target believe a falsehood, traditionalism generates paradoxes, arising from the fact that I will surely know that I want to make myself believe a falsehood. In this thesis, I argue that these well-known paradoxes need not arise under my manipulativist account of deception. In particular, I defend traditionalism about self-deception by showing that what causes (...) paradoxes is not the idea that self-deception is an intrapersonal analogue of interpersonal deception but rather our incorrect conceptions of deception, interpersonal deception, and lying. I show, by way of counterexamples, that the essence of deception is not ending up epistemically worse off but rather being intentionally manipulated into forming or retaining a certain truth-evaluable mental state. Vitally, contra the standard view, the deceiver need not hold that the mental state he intends to produce in the deceived involves a falsehood; in fact, the targeted effect may involve a proposition believed by the deceiver to be true or about whose truth the deceiver suspends belief. Any phenomenon rightly called self-deception, I argue, involves an action in which the person intentionally manipulates (by way of a trick) her own way of forming or retaining some truth-evaluable mental state of her own (belief or a belief-like thought). Thus, on the manipulativist view, a self-deceiver may non-paradoxically intend to deceive himself: the relevant intention is to affect a particular truth-evaluable thought by way of non-deviantly manipulating his agential use of his own cognitive capacities. While all cases of self-deception involve intentional manipulation of the self by the self, how this manipulative trick works out varies in different kinds of cases. In some cases, the self-deceptive manipulative trick is not intentional under that description, a description that captures the so-called deflationary view. Although the manipulativist account allows for numerous different strategies of self-deception, and is consistent with both traditionalism and deflationism, it cannot, by itself, vindicate the idea of lying to oneself. On the standard conception, lying to myself is practically impossible (if the mind is not partitioned) and this is because the very forming the intention to lie to myself – as including the intention to make myself believe my own lie – seems very unlikely. Arguably, people will not φ if they think that φ-ing is impossible. I argue that some kinds of behaviour typically understood as self-deception are actually cases in which the person is lying to herself without the intention to deceive herself; rather, she avoids legitimising an unfavourable state of affairs by openly affirming its contrary. It may also be the case, however, that some lies to oneself are aimed at deceiving – this is because, as I argue, liars need not assert what they believe is false; hence, by lying to myself, I may intend to increase my confidence in the belief I already hold. Finally, the motive for self-deception is always a matter of preserving the person’s endorsed idealised picture of reality. This account allows me to explain all possible cases of self-deception. In the last chapter, I apply my theory to some paradigmatic cases first outlined in my introduction. (shrink)

This article aims to show that it is impossible to put Cicero’s testimonies regarding The Fabius Argument in a consistent inferential order. Either we must suppose that additional premises are tacitly assumed in the text or we must com-pare it with other sources, which leads to inconsistencies in the proof’s reconstruction. Cicero’s reconstruction of the progression of the argument has formal shortcomings, and the paper draws attention to some of these deficiencies. He interpreted sources in a revised and intentionally simplified (...) way, with the aim of undermining the views of his opponents, casting them as inconsistent and similar to views held by Diodorus. Rather than being a consistently interpreted argument faithfully transcribed from the Stoic sources, Cicero’s Fabius Argument is ultimately anti-Stoic. (shrink)

This paper examines Gadamer's and Davidson's dialogical models of interpretation. It shows them to be comparable, but importantly dissimilar with respect to the kind of agreement they require for communication to be possible. It is argued that this difference entails different concepts of alterity: they model not only how we talk, but implicitly who we can intelligibly talk to. Another important contribution of this paper is to uncover a distinction in Gadamer between two kinds of agreement missed so far by (...) all commentators. The final section of this paper defends a second thesis, namely that the degree of agreement required by the models is proportional to the conceptual difference it can make intelligible. Hence, the extent of graspable cultural difference is not only an empirical matter, but is entailed by our choice of model. (shrink)

David Miller v pracích Critical Rationalism a Out of Error se jako jeden z mála Popperových žáků snaží nejen o vysvětlení a obhájení Popperova kritického racionalismu, ale zároveň i o jeho další rozvinutí.

Uvedená stať se zaměřuje právě na tuto otázku existence tzv. „dobrých důvodů“ ve spojení s racionalitou a racionálním rozhodováním a ukazuje, že Millerův požadavek neexistence „dobrých důvodů“ je nejen příliš (...) radikální, ale i nepřijatelný z hlediska Popperova nebo Musgravova pojetí kritického racionalismu.

Physicalism as a metaphysical or ontological concept has maintained a dominant position since the second half of the last century to the present day. The claim that everything is physically constituted often accompanies microphysical reductionism, which assumes the existence of fundamental laws to which everything is reducible. In this context, a question regarding the status and possible autonomy of the laws of special sciences arises. The article focuses on the basic philosophical discussions between the strong, weak, and non-reductive physicalism that (...) treat the laws of special sciences in different ways, but none of which can be considered sufficiently convincing and successful. The article seeks to prove the existence of a universal mechanism that leads to the emergence of new and complex entities and regulations of their behaviour, thus justifying the autonomous status of special sciences and laws.

Článek reflektuje Hayekovy výklady o povaze pravidel. Ukazuje, že jeho pojetí pravidel je extrémně široké a vazba mezi pravidly a pravidelnostmi je nepřijatelně úzká. Následně je nastíněno alternativní - užší - vymezení pojmu pravidla. Nakonec je podrobeno kritice Hayekovo příliš úzké chápání pojmu normativních pravidel a je navrženo jeho širší vymezení.

Essays on Aristotle's Sea-Battle, Lazy Argument, Argument Reaper, Diodorus' Master Argument -/- The book is devoted to the ancient logical theories, reconstruction of their semantic proprieties and possibilities of their interpretation by modern logical tools. The Ancient arguments are frequently misunderstood in modern interpretations since authors usually have tendency to ignore their historical proprieties and theoretical background what usually leads to a quite inappropriate picture of the argument’s original form and mission. Author’s primary intention was to draw attention to the (...) complexity of some historical arguments and to the theoretical context in which arguments were created, circulated, developed, and finally tuned. Four well-known ancient arguments – with a common central subject related to the future contingencies problem – are reconstructed from available historical sources: “The Sea Battle”, which is drawn from Aristotle’s treatise De Interpretatione; two arguments, usually ascribed to the Stoics, “The Lazy Argument” and “The Reaper”; “The Master Argument” of the Megarian philosopher Diodorus. Arguments are linguistically and semantically detaily analyzed, formally presented by reflecting some relevant corresponding hypotheses based on physical or logical theories of their ancient authors, and finally covered by appropriate logical tools familiar to a modern reader. Two appendices are added at the closing part of the book. One covering some assumptions relevant for understanding of rival streams in ancient theories of meaning related to the nature of names and naming; the other is devoted to the ancient understanding of logical proposition and attempts to find an adequate Latin translation of the Greek delicate philosophical term “ἀξίωμα”.

Leo Tolstoy’s Moralism is a call for the purification of moral universals as the foundations of culture, in which there is no contradiction between the values of an individual life and the values of the social “world.” A “moralist preacher” must fulfill two main requirements. First, he must personally fulfill the principles of his teaching. Second, he must be absolutely sure that he speaks on behalf of the truth he knows. Otherwise, his preaching will be deceptive and will serve the (...) destruction rather than creation of a moral culture. Lev Shestov rejects this pathos of preaching as incompatible with existential perception of the world. Shestov replaces “absolute morality” with the absolute of human individuality, but this absolute is incompatible with the universalism of cultural values. (shrink)

This article analyzes Nikolai Berdyaev’s ideas concerning the spiritual origins of the 1917 Russian revolution. The philosopher believed that its sources were “demons” living in the Russian national spirit, discovered and awakened in the works of the Russian classics, such as Nikolai Gogol, Fyodor Dostoyevsky, and Leo Tolstoy. The main reason these demons were able to take hold of the Russian national consciousness was the collapse of everyday life, and the false orientation of this consciousness toward a violent establishment of (...) a new social order. This order attempted to create a moral of equality and fair distribution of property, while lacking a religious-metaphysical foundation. Berdyaev’s views are compared with the contemporary realities in Russia at the time and the search for a resolution to the deep sociopolitical and moral contradictions inherent in these realities.

This paper argues that there is only one proof for God’s existence in Avicenna, and only one way for establishing the proof within his metaphysical system. This metaphysical proof is essentially derived from a priori notions, among which the notion of existence has the central role. Avicenna’s proof is structured in such a way that all its concepts are either derived from the meaning of ‘existence’ or are connected with this meaning. In this sense Avicenna’s proof sets out a scenario (...) of discursive a priori knowledge established purely on considerations of fundamental ontological meanings such as ‘existence’, ‘existent’, ‘thing’, ‘necessary’, ‘possible’, ‘impossible’, ‘one’ and ‘cause’.
