The purpose of this paper is to inquire into the relationship between persuasive definition and common knowledge (propositions generally accepted and not subject to dispute in a discussion). We interpret the gap between common knowledge and persuasive definition (PD) in terms of potential disagreements: PDs are conceived as implicit arguments to win a potential conflict. Persuasive definitions are analyzed as arguments instantiating two argumentation schemes, argument from classification and argument from values, and presupposing a potential disagreement. The argumentative structure of (...) PDs reveals different levels of disagreement, and different pos-sibilities of resolving the conflict or causing dialogical deadlock. (shrink)

Hume begins his Dialogues Concerning Natural Religion by providing a discussion on what an ideal dialogue ought to look like. Many considerations that Hume raises coincide with similar concerns in contemporary social epistemology. This paper examines three aspects of Hume’s social epistemology: epistemic peerhood, inquiry norms and the possibility of rational persuasion. Interestingly, however, I will argue that the conversation between Philo, Cleanthes and Demea falls short of meeting Hume’s articulated standard of what an ideal dialogue ought (...) to look like. From this analysis, I defend the less popular view that Demea’s decision to leave the conversation (in Part XI) was entirely reasonable and suggest an explanation for why Hume decided to make Cleanthes the ‘hero’ of the Dialogues.

In the literature, the pragmatic dimension of metaphors has been clearly acknowledged. Metaphors are regarded as having different possible uses, and in particular, they are commonly viewed as instruments for pursuing persuasion. However, an analysis of the specific conversational purposes that they can be aimed at achieving in a dialogue and their adequacy thereto is still missing. In this paper, we will address this issue focusing on the distinction between the explanatory and persuasive goal. The difference between explanation (...) and persuasion is often blurred and controversial from a theoretical point of view. Building on the analysis of explanation in different theories and fields of study, we show how it can be conceived as characterized by a cognitive and a pragmatic dimension, where the transference of understanding is used pragmatically for different dialogical goals. This theoretical proposal will be applied to examples drawn from the medical context, to show how a pragmatic approach to explanation can account for the complexity of the cases that can be found in actual dialogical contexts. -/- .

The process of cooperative problem solving can be divided into four stages. First, finding potential team members, then forming a team followed by constructing a plan for that team. Finally, the plan is executed by the team. Traditionally, very simple protocols like the Contract Net protocol are used for performing the first two stages of the process. In an open environment however, there can be discussion among the agents in order to form a team that can achieve the collective intention (...) of solving the problem. For these cases fixed protocols like contract net do not suffice. In this paper we present an alternative solution, using structured dialogues, with an emphasis on persuasion, that can be shown to lead to the required team formation. The dialogues are described formally using modal logics and speech acts. (shrink)

Remarks in Wittgenstein’s On Certainty present a view according to which all knowledge rests on commitments to things we do not know. In his usual manner, Wittgenstein does not present a clearly defined set of premises designed to support this view. Instead, the reasons emerge along with the view through a series of often cryptic remarks. But this does not prevent us from critically assessing the position (or positions) one finds in the work. This paper attempts to do that in (...) the form of a philosophical dialogue. The challenges to Wittgenstein’s view raised here center on: the extent to which hinge commitments can plausibly be regarded as rules of a language-game rather than rationally assessable propositions, mutual support versus bottom up notions of justification, the subject and context relativity of hinge commitments, the difference between justification and persuasion, whether propositions of the form p is hinge are themselves hinge, and the general viability of Wittgenstein’s view as an alternative to epistemological skepticism and Moorean anti-skepticism.

Deliberative politics should start from an adequate and differentiated image of our dialogical practices and their normative structures; the ideals that we eventually propose for deliberative politics should be tested against this background. In this article I will argue that equal respect, understood as respect a priori conferred on persons, is not and should not be counted as a constitutive normative ground of public discourse. Furthermore, requiring such respect, even if it might facilitate dialogue, could have negative effects and (...) lead to fallacious paths of thought –as seems to happen on matters of deep disagreement such as the Colorado Fundamentalist/Gay HIV issue I discuss in paragraph 6. I will put forward this argument from the standpoint of argumentation or discourse theory, drawing consequences for dialogical theories of politics. Basing my argument on a pluralistic notion of public discourse – understood as a mixed discourse of persuasion, information-seeking and negotiation – I will argue that respect is a dynamic, situational phenomenon, and that the norm of equal respect for persons is contextually contingent in political deliberation: equal respect should be considered as a potential outcome, a discursive achievement – which I understand as a second order consensus achieved dynamically on a provisional basis – rather than as an universal condition for dialogue.

This essay is my review of Randal Marlin’s fine book, Propaganda and the Ethics of Persuasion (2nd Ed.). Marlin’s book examines the concept of propaganda, rightly noting that the term has a neutral meaning of just promulgating a point of view and a pejorative meaning of using deceit to push a point of view. Marlin gives a concise history of propaganda techniques, and propaganda theory—from ancient Greece through WWII—and has a good discussion of the ethical issues involved in propaganda.

The purpose of the paper is to draw attention to a kind of rational persuasion which has received little attention in argument studies even though its existence is acknowledged in other fields. I start with a brief analysis of the debates conducted in the comments on a philosophical blog. The posts are addressed to a non-academic audience, always end with a problem, and the reader is invited to offer a solution. In the comments we hardly ever find arguments in (...) the usual sense, i.e. in the sense that an argument consists of a set of premises providing justification for a conclusion. It is not that the arguments are laid out carelessly and require a good deal of reconstruction: typically, there is no argument to reconstruct. The author simply states his view, then goes on to sketch a larger picture of which his view is a part. In the responses to the comments we find the same: identification of the point of disagreement, no argument, elaboration of the preferred view in some detail. One might say that this is just a failure of rational discussion; in pragmadialectical terms, the discussion gets stuck in the opening stage. But there is another way of looking at the matter. Since the participants do not have sufficiently rich common background knowledge to take premises from, they cannot offer arguments proper and must resort to a different sort of rational persuasion. They try to show that their view can be extended into a larger, coherent picture. This makes good sense from an epistemological point of view. If a view is false, in trying to work out its details we sooner or later run into problems, so allowing coherent elaboration provides some degree of justification. One might say that the participants argue in the broad sense of trying to persuade by rational means, but they do that without adducing arguments proper. The claim that there is a way of rational persuasion which does not proceed by arguments proper can be further substantiated by noting that there debates whose status as rational discussion, as opposed to the comments on the philosophical blog, is not controversial. In discussing the work of some outstanding contemporary philosophers Gary Gutting argues that even though they do offer arguments, it is not by their arguments that they have convinced others of the viability of their approach, but by what he calls „persuasive elaboration”. We may also think of Kuhn’s account of the debates surrounding changes in paradigms: the arguments fail to persuade because their premises are not shared, but showing that the new paradigm can be extended to a vast variety of phenomena eventually succeeds. I finish by listing some questions this kind of rational persuasion may raise for argument studies. (shrink)

This paper is aimed at combining the advances in argumentation theory with the models used in the field of education to address the issue of improving students’ argumentative behavior by interacting with an expert. The concept of deeper or more sophisticated argumentative strategy is theoretically defined and used to advance two new coding schemes, based on the advances in the argumentation studies and aimed at capturing the dialectical, or structural, behavior, and the argumentative content of each dialogue unit. These (...) coding schemes are then applied for a qualitative analysis of a study designed to investigate how students’ argumentative behavior can be influenced by the interaction with an expert, who used specific types of attacks to the interlocutors’ positions. The twofold coding shows at which dialogical level expert–peer interactions can directly and more stably affect students’ argumentative behavior, and what effects such more sophisticated strategies can have on the discussion and the analysis of disagreements. In particular, this paper shows how a specific type of deep-level attack, the underminer, can open dialogues of a different level, focused on unveiling and debating background beliefs underlying a specific position.

This paper explores Plato’s views on the purpose of rhetorical form by surveying the way in which Socrates engages in speechmaking at several points in the Gorgias. I argue that Socrates has nothing in principle against the use of a long speech as part of the practice of philosophical inquiry and argument, provided that the speech is geared toward understanding. This reflects a key and relatively unremarked distinction that Socrates makes in the Gorgias between persuasion that comes from being (...) convinced and persuasion that comes from being taught. The kind of long speeches that Socrates objects to are those that have a conviction-based purpose. However, this leaves open the use of a wide variety of rhetorical techniques—pieces of argument, speechifying, analogy, myth, and exhortation—that have a teaching-based purpose, which is precisely the sort of rhetoric that Socrates licenses in the dialogue.

This paper analyses a hitherto unknown technique of using logic diagrams to create argument maps in eristic dialectics. The method was invented in the 1810s and -20s by Arthur Schopenhauer, who is considered the originator of modern eristic. This technique of Schopenhauer could be interesting for several branches of research in the field of argumentation: Firstly, for the field of argument mapping, since here a hitherto unknown diagrammatic technique is shown in order to visualise possible situations of arguments in a (...) dialogical controversy. Secondly, the art of controversy or eristic, since the diagrams do not analyse the truth of judgements and the validity of inferences, but the persuasiveness of arguments in a dialogue. (shrink)

I have two main goals in this paper. The first is to argue for the thesis that Kant gave up on his highest good argument for the existence of God around 1800. The second is to revive a dialogue about this thesis that died out in the 1960s. The paper is divided into three sections. In the first, I reconstruct Kant’s highest good argument. In the second, I turn to the post-1800 convolutes of Kant’s Opus postumum to discuss his (...) repeated claim that there is only one way to argue for the existence of God, a way which resembles the highest good argument only in taking the moral law as its starting point. In the third, I explain why I do not find the counterarguments to my thesis introduced in the 1960s persuasive. (shrink)

In this paper, we analyze and discuss Schopenhauer’s n-term diagrams for eristic dialectics from a graph-theoretical perspective. Unlike logic, eristic dialectics does not examine the validity of an isolated argument, but the progression and persuasiveness of an argument in the context of a dialogue or even controversy. To represent these dialogue situations, Schopenhauer created large maps with concepts and Euler-type diagrams, which from today’s perspective are a specific form of graphs. We first present the original method with Euler-type (...) diagrams, then give the most important graph-theoretical definitions, then discuss Schopenhauer’s diagrams graph-theoretically and finally give an example of how the graphs or diagrams can be used to analyze dialogues.

Through the analysis of political speeches and legal arguments, the book offers a systematic study of emotive language in argumentation, (...) rhetoric, communication, political science and public speaking.

Techne and Truth. The problem of techne in the dispute between Gorgias and Plato -/- The source of the problem matter of the book is the Plato’s dialogue „Gorgias”. One of the main subjects of the discussion carried out in this multi-aspect work is the issue of the art of rhetoric. In the dialogue the contemporary form of the art of rhetoric, represented by Gorgias, Polos and Callicles, is confronted with Plato’s proposal of rhetoric and concept of art (...) (techne). The ingenuous and dramatic structure of the dialogue composed of three acts, in each of which Socrates’ consecutive interlocutors emerge, is difficult to interpret. It seems, however, that even though the first conversation between Socrates and Gorgias constitutes a small part of the dialogue, it forms the foundations for the discussion. This part, dealing with such important issues as the subject of art, knowledge, power and relation between art and good, is the starting point for the conversations which follow. What do the differences between the Gorgias’ and Plato’s concepts of art consist in? Any attempt to answer the question requires presentation of the background for the discussion taking place in Plato’s work as well as the reconstruction of Gorgias’ vision of the art of rhetoric and art in general, defining the relation between art and knowledge. The latter may be undertaken on the basis of two paraphrases of the treatise “On Non-existence”, two epideictic speeches entitled “Helen” and “Palamedes” and some smaller fragments which have been preserved from Gorgias’ creative output. The treatise “On Non–existence”, very paradoxical in its philosophical meaning, testifies to new, sophistic thinking represented by Gorgias of Leontinoi. The treatise is the polemic and attack on Eleatism based on certain principles and methods elaborated by the Eleatics themselves. It also shows that Gorgias – using traditional Eleatic schemes – is opposed to this tradition. Even though the treatise does not discuss the problem of art directly, it anticipates the considerations from epideictic speeches. “Helen” and “Palamedes” constitute further stages in the development of Gorgias’ thought and concept of art combining typically epideictic elements with some philosophical convictions. Gorgias refers to the Eleatic theme considering the issues of truth, knowledge and belief, yet defining them in the empirical spirit. Solutions in the cognitive sphere determine the horizon of Gorgias’ rhetoric. The word is separated from the existence. Human cognition is limited and therefore the word and visual images affect the belief. This promotes the great importance of rhetoric, painting and sculpture, i.e. the areas which influence in a specific way – creating the “delusion” (ἀπάτη). Through idealization art provides pleasure, which is its objective. Therefore the task of art is to create delusion. The rhetor of Leontinoi discusses the issue of “how?” to use the word ‘rhetoric’. Gorgias is aware that rhetoric may be used to talk about what is unknown and that technical correctness of a rhetoric statement is not identical with the truthfulness of the proclaimed message. Mentioning it, Gorgias shows his respect to the truth as a value which should be respected in speech on the one hand, and on the other emphasizes that the truth in itself has no persuasive power. For this reason it is not enough to proclaim the truth, but, to convince the listeners, the orator should possess the skill of speaking. What is then the relation between truth and art emerging from epideictic speeches? Gorgias undoubtedly emphasizes the formal aspect of speech, as rhetoric is art, thus an ability based on certain principles. According to Gorgias, the truth is the value which should be respected in speeches. Rhetoric is able to create a fictive world, as a great range of reality remains outside direct human experience. Rhetoric does not oppose the truth but discussing not only what is directly given concerns the area outside the sphere of direct experience. This concept of rhetoric is the basis of the discussion about art carried out in the dialogue “Gorgias”. Even though the first of the discussions in the dialogue – the conversation between Socrates and Gorgias – is directly concerned with rhetoric itself, numerous remarks testify to its much wider character. This is best exemplified by the way of carrying out the conversation by Socrates, who, asking questions about rhetoric practised by Gorgias, throughout the whole conversation compares it with other skills. Additionally, the manner and the structure of the conversation prove that Plato considers the issue of rhetoric from a wider perspective determined by the issue of art. The specific feature of the conversation is ordering it around main issues – such notions as πρᾶγμα, ἐπιστήμη, δύναμις, each of which has its own meaning in Plato. In the first part of Gorgias Plato presents the principles previously occurring in other dialogues in a certain order, thus constructing the structure of the conversation with Gorgias. The notions are not novum in Plato but the fact that he clearly wants to systematise them and present a certain concept of art is a new and significant aspect. This tendency is of paramount importance for the discussion because Gorgias’ answers are evaluated by Plato from the perspective of this clearly set concept consisting of not only established notions but also certain principles. The discussion between Socrates and Gorgias introduces a theme which is crucial for the dialogue: the relation between art and good, i.e. the technical and ethical spheres. The issue is introduced by Gorgias, who mentions that rhetoric may be used for evil purposes. On this basis Socrates proves that if rhetoricians can use rhetoric for evil purposes, they have no knowledge concerning the subject of their art – justice, because one who knows what is just, always acts justly. Thus the relation between the technical and ethical spheres transpires to be the main point of contention. The question is whether a technician following the principles of the art he practices may act against good. This paradoxical statement based on the well-known Socrates’ principle "nemo sua sponte peccat" acquires philosophical foundations in the dialogue. In its remaining two parts Plato presents a justification, placing the principle within the framework of a certain concept of art, as a result of which not only rhetoric but also many other skills are criticised. The notions on which the conversation with Gorgias focuses are more precisely defined in the subsequent parts of the dialogue. Additionally, Plato presents twice the conditions which art should fulfill. They oblige the “technicians” to know the nature and purpose of the art and to know the causes of undertaken activities and to be able to justify them. These conditions determine the relation between the two spheres – technical and ethical. According to Plato, art may not act against good because it should be the objective of its activities. Certain concepts of good and knowledge outlined in the dialogue are the guarantees of “technicality”. Good, which should be respected by every art, is understood objectively and is contrasted with subjective pleasure. Knowledge, which should be the basis of art, opposes experience, which uses observation and recollection. Additionally, the definition of knowledge, significance of order in the world assuming the form of “geometrical equality”, significance of mathematics becoming the ideal of exactness indicate that Plato’s concept of knowledge is formed in Gorgias. These conclusions render it impossible that the results of any activity deserving the name of art should oppose good. And this is Plato’s main reproach of Gorgias’ concept, who wrote about false speeches possessing the power of conviction because they were written according to the principles proof of art or who defined tragedy as “a deceit, where he who cheats is more just than he who does not and the cheated is wiser than he who was not cheated”. Such determination of the relation between the technical and ethical sphere resulted from Gorgias’ concept of the world and fundamental philosophical principles. The whole concept of art described by Plato in the dialogue opposes the view presented by Gorgias. According to Plato, every technical activity has a defined object (ἔργον), is based on knowledge (ἐπιστήμη) and is always aimed at the good of human soul or body. The danger revealed and presented in the dialogue by Plato exists in the very concept of art presented by Gorgias, i.e. in its empirical foundations and the resulting understanding of the relation between art and good. Gorgias’ concept of art based on empirical cognition, which concerns the world of phenomena and rejects the possibility of perfect knowledge, leads, according to Plato, to a dangerous falsification of the relation between art and good. Plato proves that this weakness of Gorgias’ concept is revealed when confronted with these representatives of “the magnificent art” who are not protected against radicalism by the adherence to the moral tradition. The comparison of two, completely contrasting concepts of art based on different philosophical understanding of knowledge and good is decisive for the criticism of rhetoric in Gorgias. The concept presented by Plato criticises contemporary rhetoric and sophistry but determines the direction of research of the real art of rhetoric. (shrink)

This paper is the product of an interdisciplinary, interreligious dialogue aiming to outline some of the possibilities and rational limits of supernatural religious belief, in the light of a critique of David Hume’s familiar sceptical arguments -- including a rejection of his famous Maxim on miracles -- combined with a range of striking recent empirical research. The Humean nexus leads us to the formulation of a new ”Common-Core/Diversity Dilemma’, which suggests that the contradictions between different religious belief systems, in (...) conjunction with new understandings of the cognitive forces that shape their common features, persuasively challenge the rationality of most kinds of supernatural belief. In support of this conclusion, we survey empirical research concerning intercessory prayer, religious experience, near-death experience, and various cognitive biases. But we then go on to consider evidence that supernaturalism -- even when rationally unwarranted -- has significant beneficial individual and social effects, despite others that are far less desirable. This prompts the formulation of a ”Normal/Objective Dilemma’, identifying important trade-offs to be found in the choice between our humanly evolved ”normal’ outlook on the world, and one that is more rational and ”objective’. Can we retain the pragmatic benefits of supernatural belief while avoiding irrationality and intergroup conflict? It may well seem that rationality is incompatible with any wilful sacrifice of objectivity. But in a situation of uncertainty, an attractive compromise may be available by moving from the competing factions and mutual contradictions of ”first-order’ supernaturalism to a more abstract and tolerant ”second-order’ view, which itself can be given some distinctive intellectual support through the increasingly popular Fine Tuning Argument. We end by proposing a ”Maxim of the Moon’ to express the undogmatic spirit of this second-order religiosity, providing a cautionary metaphor to counter the pervasive bias endemic to the human condition, and offering a more cooperation- and humility-enhancing understanding of religious diversity in a tense and precarious globalised age.

Presumption is a complex concept in law, affecting the dialogue setting. However, it is not clear how presumptions work in everyday argumentation, in which the concept of “plausible argumentation” seems to encompass all kinds of inferences. By analyzing the legal notion of presumption, it appears that this type of reasoning combines argument schemes with reasoning from ignorance. Presumptive reasoning can be considered a particular form of reasoning, which needs positive or negative evidence to carry a probative weight on the (...) conclusion. For this reason, presumptions shift the burden of providing evidence or explanations onto the interlocutor. The latter can provide new information or fail to do so: whereas in the first case the new information rebuts the presumption, in the second case, the absence of information that the interlocutor could reasonably provide strengthen the conclusion of the presumptive reasoning. In both cases the result of the presumption is to strengthen the conclusion of the reasoning from lack of evidence. As shown in the legal cases, the effect of presumption is to shift the burden of proof to the interlocutor; however, the shift a presumption effects is only the shift of the evidential burden, or the burden of completing the incomplete knowledge from which the conclusion was drawn. The burden of persuasion remains on the proponent of the presumption. On the contrary, reasoning from definition in law is a conclusive proof, and shifts to the other party the burden to prove the contrary. This crucial difference can be applied to everyday argumentation: natural arguments can be divided into dialectical and presumptive arguments, leading to conclusions materially different in strength. -/- .

In this paper, I propose a logical-cognitive approach to argumentation and advocate an idea that argumentation presupposes that intelligent agents engaged in it are cognitively diverse. My approach to argumentation allows drawing distinctions between justification, conviction and persuasion as its different kinds. In justification agents seek to verify weak or strong coherency of an agent’s position in a dialogue. In conviction they argue to modify their partner’s position by means of demonstrating weak or strong cogency of their positions (...) before a ‘rational judge’. My approach to argumentation employs a ‘light’ version of Dung’s abstract argumentative frameworks. It is based on Stich’s idea of agents’ cognitive diversity the epistemic aspect of which is argued to be close to Pavilionis’s conception of meaning continuum. To illustrate my contributions I use an example based on the Kitchen Debate (1959) between Khrushchev and Nixon. (shrink)

A philosophical exchange broadly inspired by the characters of Berkeley’s Three Dialogues. Hylas is the realist philosopher: the view he stands up for reflects a robust metaphysic that is reassuringly close to common sense, grounded on the twofold persuasion that the world comes structured into entities of various kinds and at various levels and that it is the task of philosophy, if not of science generally, to “bring to light” that structure. Philonous, by contrast, is the anti-realist philosopher (though (...) not necessarily an idealist): his metaphysic is stark, arid, dishearteningly bone-dry, and stems from the conviction that a great deal of the structure that we are used to attribute to the world out there lies, on closer inspection, in our head, in our “organizing practices”, in the complex system of concepts and categories that unrerlie our representation of experience and our need to represent it that way.

Asking about the place of religion in a democratic society refers straightforwardly to the kind of pluralism we adopt. Given that intra-societal tensions mark out a democratic pluralistic society, then it seems that there is no doubt that there should be a place for religion and religious people in it. What is crucial for a democratic society is taking a suitable view on pluralism. There could be, at least, two versions of pluralism: Incommensurable or radical and commensurable or moderate. It (...) is argued that the incommensurable account of pluralism confronts with serious problems both theoretically (like the impossibility of outer critique) and practically (like replacing persuasion with force). Rorty advocates a commensurable pluralism based on pragmatic conventions or "know-how" skills without any meta-narrative or translation manual among the doctrines of rival views. However, along with Davidson, it is stated that some kind of translation among the rival views is inevitable. In addition, it is argued that commensurable pluralism could not be limited to merely know-how skills and it needs some know-that insights. This view of pluralism not only opens the door of dialogue, but also provides a basis for removing superficial differences or conflicts between the rivals. Real differences, however, could remain and should be tolerated. (shrink)

This book presents a new account of Thales based on the idea that Acheloios, a deity equated with water in the ancient Greek world and found in Miletos during Thales’ life, was the most important cultic deity influencing the thinker, profoundly shaping his philosophical worldview. In doing so, it also weighs in on the metaphysical and epistemological dichotomy that seemingly underlies all academia—the antithesis of the methodological postulate of Marxian dialectical materialism vis-à-vis the Platonic idea of fundamentally real transcendental forms. (...) Unbeknownst to many scholars, there are various Neo-Marxian thinkers that position the origin of coinage as the pivotal technological development giving rise to impersonal “metaphysical cosmology,” suggesting that the value of money was more-or-less projected back onto the cosmos in the form of “ideal substances.” While the arguments are incredibly sophisticated and persuasive, their conclusions (either stated or implied) are rather difficult to swallow: the self is merely an illusion, abstract ideas of an ultimate source of value, like God or the Good, are totally delusional (as is the soul, and presumably any notion of inherent human dignity), and essentially everything is reducible to mankind’s enslavement to commodities and the notion of our own objectified labor, which is the true source of all value according to Marx. Not only is this an alarming belief that many scholars (consciously or unconsciously) have adopted, since essentially any action could be “justified,” it is also demonstrably false, since it rests on a misunderstanding of Thales and misconception of philosophy as such. -/- My work rectifies that misunderstanding. In an important sense, it is an attempt at redefining philosophy as a “love of wisdom,” which I argue was accurate even in the Presocratic setting, and it uses the influence of Acheloios on Thales to do so. Throughout its pages I explore the etymology and historical uses of the word ὔδωρ, examine the archaeological context of 7th to 6th century Miletos, consider various aquatic myths Thales encountered, and highlight a hitherto overlooked tradition stemming from Thales and influencing such thinkers as Pythagoras, Empedokles, and Hippo, which culminates in a completely new reading of Plato’s Phaedrus, a dialogue in which Plato responds to the exact type of thinking employed by the Neo-Marxians. It is there that we find Socrates and Phaedrus surrounded by the iconography of Acheloios and the nymphs, all while they lie reclined like river gods (the sinews of Acheloios) on the banks of the Ilisos. And it is in that dialogue that Plato defines philosophy as a love of wisdom—the beholding of a multiplicity of hermeneutical frameworks—and alludes to the fact that it began with the sacrifice of Acheloios, the initial philosophical maneuver which he attributes to Thales. The book ends with a threefold rejoinder to the Neo-Marxian school, corresponding to the λόγος, μῦθος, and ἔργον of Acheloios. It turns out that, (1) the λόγος of Acheloios contained the ideal preconditions conducive to an abstraction to a more refined philosophical worldview in which divine water operated as the One among the Many; (2) the μῦθος of Acheloios actually encouraged the application of the notion of sacrifice to Acheloios himself (thus revealing his essence as divine water); and, (3), the ἔργον of Acheloios, in which he kneels in assent to sacrifice, is found on a coin that was probably designed by Thales. In the final analysis, I suggest that the tradition of Acheloios is reflective of a greater philosophical truth, and that by following Thales’ lead, we transcend the Marxian hermeneutic of doubt and reorient ourselves toward the οὐσια ὄντως οὖσα.

The relationship between teaching and argumentation is becoming a crucial issue in the field of education and, in particular, science education. Teaching has been analyzed as a dialogue aimed at persuading the interlocutors, introducing a conceptual change that needs to be grounded on the audience’s background knowledge. This paper addresses this issue from a perspective of argumentation studies. Our claim is that argumentation schemes, namely abstract patterns of argument, can be an instrument for reconstructing the tacit premises in students’ (...) argumentative reasoning and retrieving the background beliefs that are the basis of their arguments. On this perspective, the process of premise reconstruction is followed by a heuristic reasoning process aimed at discovering the students’ previous intuitions that can explain the premises and concepts that are left unexpressed in their arguments. The theoretical insights advanced in this paper are illustrated through selected examples taken from activities concerning predictive claims on scientific issues. (shrink)

Metaphors are considered as instruments crucial for persuasion. However, while their emotive, communicative and persuasive effects are the focus of different studies and discussions, the core of their persuasive function, namely their argumentative dimension, is almost neglected. This paper addresses the problem of explaining how metaphors can communicate arguments, and how it is possible to reconstruct and justify them. To this purpose, a distinction is drawn between the arguments that are communicated metaphorically and reconstructed “top down,” namely based on (...) relevance considerations, and the ones that are triggered implicitly by the use of a metaphorical expression. In both cases, metaphorical arguments are reconstructed through different patterns of argument, called argumentation schemes (Walton, Reed & Macagno 2008). However, while the purpose of a metaphorical sequence of discourse (called metaphorical move) can guide and justify the reconstruction of the argument that can sufficiently support the intended conclusion in a persuasive move, a more complex analysis is needed for analyzing the inferences that a metaphorical move can trigger. These inferences are claimed to represent part of the connotation of the metaphorical expression and can be captured through its most frequent collocations, determinable using some tools of the corpus linguistics.

This dissertation identifies and explains four major contributions of the Laws and related late dialogues to Plato's moral and political philosophy. -/- Chapter 1: I argue that Plato thinks the purpose of laws and other social institutions is the happiness of the city. A happy city is one in which the city's parts, i.e. the citizens, are unified under the rule of intelligence. Unlike the citizens of the Republic, the citizens of the Laws can all share the same true judgments (...) of value, and this unanimity explains the city's unity. Plato thinks that aiming at the city's happiness is justified, moreover, because a unified city contributes to the universe's order. -/- Chapter 2: In the Laws, Plato holds that the sick, poor, ugly, weak, but virtuous are happy, and that health, wealth, beauty, and strength benefit the virtuous but harm the vicious. Only in the Laws does Plato commit himself to all these claims simultaneously, and I explain how the moral psychology of the Laws permits Plato to maintain them coherently. -/- Chapter 3: I argue that, in the Laws, becoming virtuous is the same as becoming like God. Becoming like God does not require escape from the world of change as it does in the Theaetetus, however. Rather, becoming like God requires bringing "measure" or appropriate order to the world of change, especially to those entities over which we have the most control—our own souls. In the Laws, citizens achieve this order as they learn to be just and to understand the nature of reality. -/- Chapter 4: Unlike the Republic and Statesman, the Laws holds that obedience of the citizens to their laws should be effected, if possible, with rational persuasion. I argue that Plato wishes such persuasion to educate the citizens of the reasons for the laws. Understanding the laws' justification is the principal way in which citizens acquire the good judgment necessary for virtue. The city becomes more happy as the citizens progress in virtue, so rational persuasion is a necessary means to the lawgiver's overall aim. (shrink)

Pascal’s wager is the name of an argument in favor of belief in God presented by Blaise Pascal in §233 of Thoughts. Ian Hacking (1972) pointed out that Pascal’s text involves three different versions of the argument. This paper proceeds from this identification, but it concerns an examination of the rhetorical strategy realized by Pascal’s argumentation. The final form of Pascal’s argument is considered as a product that could be established only through a specific process of persuasion led with (...) respect to an intended reader with a particular set of initial beliefs. The text uses insights from the pragma‐dialectical approach to argumentation, especially the concept of rhetorical effectiveness of particular choices from the topical potential. The argumentation structure of Pascal’s wager is considered to be a reflection of the anticipated course of dialogue with the reader critically testing the sustainability of Pascal’s standpoint “You should believe in God”. Based on the argumentation reconstruction of three versions of the argument, Pascal’s idea of opponent/audience is identified. A rhetorical analysis of the effects of his argumentative strategy is proposed. The analysis is based on two perspectives on Pascal’s argument: it examines the strategy implemented consistently by all arguments and the strategy of a formulation of different versions of the wager.

The confessional work of the Church has been from the very beginning a foundation and basis for the Divine Truth. Starting from this real necessity, the Apologetic Theology claims some important research directions, grounded on the Holy Scripture and the Holy Tradition. Given this historical and doctrinal context, we can highlight the next support coordinates of the Christian Apologetics background: “the truth of God’s existence, the reality of the supernatural world and man’s immortality. All of this are, as we can (...) say, the Christian specific starting from the first ages. The truths about the divine origin of Christianism are to be found here, on the dignity of this revealed doctrine, on the divine-human character of his Founder, on the importance and necessity of Christian Church for the religious and morale life of human kind”. . Apologetics and (or) Fundamental Theology The reason why the Church must justify her teaching in the context of her missionary activity does not rise up from inner necessity. It does more from external misconceptions. In this context we can define the main concern of apologetics as a theological discipline. On the other hand, one can discover almost the same meaning in Fundamental Theology. However, as a difference between them, Fundamental Theology is interested in the direction and bears informative message, since “it aims at basic religious principles systematic presentation, both external and internal, as well as their justification before the scientific-theological conscience of believers. Thereafter, Christianity can be considered the only true religion”. On the other hand, one can claim that the name of “Apologetics” rises up from the necessity that the Christian arguments must be scientifically enforced and illustrated externally. Therefore, the mission of Christian Apologetics is to reject the anti-Christian objections through the power of the theological arguments in dialogue with philosophy, culture or science. In fact, even the object of Apologetics is "the scientific ground of Christian truths" with the purpose to "offer the Truth, reject error, and eradicate lies." In order to achieve its goal, Christian Apologetics offers us a positive method, which consists in "a logical and direct development of a certain thesis, in clarifying a certain truth, by revealing its content and the outcomes deriving from it". Therefore, we have a very dynamic field through which this discipline comes and supports the active life of the Church. Moreover, the method of the Apologetics as a theological subject is based on a conceptual struggle, very active starting with the very first centuries of the Early Church. Due to its energetic character, Fundamental Theology won its most important place among Christian doctrines. “Through struggle, Fundamental Theology imposed itself as a theological subject and became individualised. Through struggle and only through struggle, Fundamental Theology must exist and strengthen the positions of Christianity”. In its theologically mission, Christian Apologetics identifies and also prevents the alteration of the doctrinal truth. In this concern, it has the responsibility to enforce of believers’ moral conscience in their spiritual process of development. As a subject, one can say that the mission of Apologetics is “rational, objective and represents a very important basis for the Christian truths of faith”. Therefore, one can notice that the most important aspect of our subject is to enforce the Christian faith and experience through proper knowledge of the fundamental principles of the doctrine. This is the reason why we also mention Apologetics together with Fundamental Theology. However, we must highlight a few important details regarding the sensible difference between both of the denominations. Therefore, historically speaking, “they both arise from those who personally share Christian faith and act within the believing community and in its service. They both aim to respond to objections raised by critics and to offer a trustworthy account of main beliefs about matters as the existence of a personal God, the divine self-revelation in Jesus Christ, and the nature of faith”. On the other hand, we can identify almost three important differences between Apologetics and Fundamental Theology. “First, a Christian apologist can simply address a question: does the existence of horrendous evil in our world rule out the existence of almighty and all-loving God? or has science caused faith in God to be demoted in the past? … Second, good Apologetics has typically a sharply defined audience: Apologetics can seek, for example, to alert non-believers to the weakness of the case currently being against God and religion. But Fundamental Theology addresses to a wider range of readers … Third, polemics (in the good sense of this word and not as mindless ranting) belong to the exercise of Apologetics … The tone of fundamental theologians, even when rebutting objections to Christian faith, is or should be more expository and less polemically inclined to illustrate defects in opposing positions”. Moreover, we must mention that Apologetics can be considered as a particular subject. Although, it is similar in terms of content with Dogmatic and Philosophy through its method, our subject has its own research direction. Therefore, if Dogmatic is defined by an expositive and imperative character, Apologetics is demonstrative and constraining. In other words, dogmatic rationality, which has a subsidiary role, in Apologetics becomes primordial. In this case, “the faith truths become truths also for the rationality and moreover, the eternal truths of the Divine Reason become constraining for the human reason, too. Truths of natural religion, which are in fact the object of the Philosophy of Religion, are conditioned in Apologetics by the Absolute Truth completed in the Christian faith”. In all its theological and external interaction perspectives, Apologetics holds the main role to “expose, defend and justify with rational meanings the general truths of religion”. It is necessary to clear up one aspect: as subject, Apologetics is different from Apology. On the one hand, one can speak about the general research background and, on the other hand, one can describe a singular part of theological approach. Therefore, these two “theological sisters” are different depending on the type of approach. However, Apology is older than Apologetics. Among the first Christian apologists, we mention: Saint Justin the Martyr and Philosopher, Tatian, Athenagoras or Tertullien. In its current meaning, Apologetics is of a western theological origin, having its beginning in Middle Ages. Even so, its blooming age is the 18th century, when the Western Catholic Church replied to the materialist and atheistic philosophy. In the Eastern Church this type of confession had a more profound theological overview, in a theonomic perspective. “In the light of the Holy Scripture, the eastern theological thinking always shows priority to the divine Revelation in spite of the philosophical human systems and places the Creator - Logos at the basis of all creation, in the light of biblical thoughts”. -/- II. “Rational-spiritual Apologetics” Reverend Professor Dumitru Popescu, one of the most important Romanian theologians, develops the concept of “Rational-spiritual Apologetics”. In his theological approach, he illustrates the fact that one of the most essential part of the Church’s confessional work are the relations between rational arguments and spiritual purpose of the Christian life. In this case, we can identify two possibilities of argumentation: rational and spiritual, each of them in connection with the knowledge of God. This is in fact, the Orthodox specificity of the Apologetics, as theological subject, in contrast with the principles of western scholastic. Therefore, the most important argument, which Dumitru Popescu brings up in the support of his thesis, belongs to Saint Maximus the Confessor’s theology: “The Scripture provide a double knowledge of the divine things. One is relative and consists in its rationality and meanings, without the direct feeling of God. Through it we are guided in this life. The other one is in a true sense true and consists in leaving experience of divine grace, outside rationality and meanings, having the complete experience of God. Through it we will receive in the future life the deification”. On the other hand, we can understand that the purpose of human rationality is not to replace the spiritual perspective, since human mind does not own the divine mystery. In this case, rationality can be useful in discovering and demonstrating the existence of God from natural realities to a point where we must assume a spiritual understanding. Consequently, in the context of human deification, the orthodox theology cannot conceive the gnoseological process in rational terms. Therefore, Rev. Dumitru Popescu carries out a dual argumentation: 1. since God is not a solitary power, but descends and interacts with man providentially (through His divine grace and energies); 2. because the created world doesn’t have an independent rationality through which man can receive the possibility to reach God. Therefore, Father Professor Dumitru Popescu concludes that “the deification process is here, on the earth, a foretaste of immortality, which springs from the personal meeting of man with God”. One of the most recent Romanian Apologetics academically approach is the book of professor Adrian Lemeni: “Truth and Demonstration”. Except his very complex analysis on the interaction between theology and science, Professor Lemeni goes further and perfects Dumitru Popescu’s theological view, on the “Rational-spiritual” character of Orthodox Apologetics. Therefore, he offers a very important example, starting from Saint Gregory Palamas’ theological view. In his work “the authority of Patristic gnoseology” is illustrated, which is offered by the “Eternal Truth, God’s Word, incarnated in the Person of Jesus Christ”. “The authority of patristic gnoseology” – notes down Adrian Lemeni – “is expressed along the process for searching the truth of knowledge illustrated by deeds and life. In his debate with Varlaam from Calabria, Saint Gregory Palamas insists on the power of persuasion which arises from the Church’s Tradition, biblical and patristic fundamentally. In an ultra-confident argument, based on the autonomic logical power, we believe that one word has power over another. But Saint Gregory Palamas shows that the truth is based and validated through spiritual and ecclesiastical experience. Truth is validated by the words and deeds of the Holy Fathers, in direct connection with apostolic Tradition. Any argument can be fought against by another argument. Nevertheless, the apologetic concession based on the deeds of the saints is unbookable. This is the thesis which Saint Gregory Palamas develops in complete harmony with the patristic gnoseological Tradition”. Therefore, we can consider that the position of the subject of Apologetics (of Fundamental Theology) is one of interactions. It has connections with all domains external to Theology. In this case, we can consider it sets up a dialogue or debate with philosophy, culture or science. Starting from the historical argument, this interaction between theology and other sciences has existed from the very first Christian century. Therefore, we have an apologetic literary genre starting with the first patristic writings. Including the Early Church, we can identify three important stages in terms of historical apologetics development: 1. The Christian apologists struggle age with Judaism and paganism; 2. From the issue of Islam to the Middle Eve; 3. From the period of the Renaissance of Western sciences to the present day. (shrink)

Sokrates var inte bara en filosofisk nydanare. Genom sitt sätt att involvera sina samtalspartners i den filosofiska processen var han också i hög utsträckning en pedagogisk nydanare. Hans pedagogiska grundidé var den så kallade majeutiska metoden – det vill säga ”barnmorskemetoden”. Med det menade han att han inte överförde sina egna färdiga tankar till den han talade med utan han hjälpte sin samtalspartner att föda sina egna tankar. Inom pedagogiken är det vanligt att använda den så kallade ”Sokratiska metoden” vilket (...) i sin enklaste form bara innebär att man ställer frågor till studenterna. Den här artikeln kommer emellertid att handla om en mer sofistikerad metod som används för begreppsanalys/begreppsdefinition i grupp. Metoden är inspirerad av Sokrates men skiljer sig också en del från hur Sokrates själv grep sig an sina dialoger – åtminstone så som de beskrivs av Platon. Artikeln innehåller en kort historisk och pedagogisk bakgrund men syftar framför allt till att utgöra en praktisk vägledning för genomförande av sokratiska dialoger i filosofiundervisningen. Artikeln bygger framför allt på mina egna erfarenheter av att använda Sokratisk Dialog i undervisningen vid Filosofiska institutionen vid Lunds universitet, Lunds Tekniska Högskola, Sveriges Lantbruksuniversitet och i det privata näringslivet. Artikeln vänder sig till alla som undervisar i filosofi på universitetet eller gymnasiet eller i filosofiska metoder för studenter vid andra utbildningar, t.ex. värdeteori, vetenskapsteori eller tillämpad etik för ingenjörer eller medicinare – eller i vilket annat ämne som helst där det förekommer begrepp som saknar en enkel och knivskarp definition men som är viktiga för ämnet.

Political persuasion can express moral respect. In this article, however, I rely on two psychological assumptions to argue that political persuasion is generally prima facie disrespectful: (1) that we maintain our political beliefs largely for non-epistemic, personal reasons and (2) that our political beliefs are connected to our epistemic esteem. Given those assumptions, a persuader can either ignore the relevant personal reasons, explicitly address them, or implicitly address them. Ignoring those reasons, I argue, constitutes prima facie insensitivity. Explicitly (...) addressing them constitutes a form of prima facie incivility. Finally, implicitly addressing them covertly treats those personal reasons as psychological puppet strings, constituting prima facie objectionable manipulation. This prima facie insensitivity, incivility, and manipulation are each prima facie failures of respect, either for the persuadee’s rationality or for their agency. Political persuasion can sometimes be all-things-considered justified, but these moral hazards can produce reasonable guilt, resentment, and blowback. (shrink)

Many of us hold false beliefs about matters that are relevant to public policy such as climate change and the safety of vaccines. What can be done to rectify this situation? This question can be read in two ways. According to the descriptive reading, it concerns which methods will be effective in persuading people that their beliefs are false. According to the normative reading, it concerns which methods we are permitted to use in the service of persuading people. Some effective (...) methods—a programme of brainwashing, say—would not be permissible. In this paper I compare “methods of rational persuasion” with what you might call “marketing methods” such as how one frames the problem of climate change. My aim is to show that “marketing methods” are preferable to “methods of rational persuasion”. My argument has two parts. First, I argue that the evidence suggests that “marketing methods” are more effective in persuading people to change their minds. Second, I argue that “marketing methods” are an acceptable response to the normative question. (shrink)

In Plato’s Laws, the Athenian Stranger maintains that law should consist of both persuasion (πειθώ) and compulsion (βία) (IV.711c, IV.718b-d, and IV.722b). Persuasion can be achieved by prefacing the laws with preludes (προοίμια), which make the citizens more eager to obey the laws. Although scholars disagree on how to interpret the preludes’ persuasion, they agree that the preludes instill true beliefs and give citizens good reasons for obeying the laws. In this paper I refine this account of (...) the preludes by arguing that the primary purpose of the preludes is to motivate correct action, and that for citizens who lack rational-governance this is achieved via useful false beliefs. That is to say, in many cases, the prelude functions as a “noble lie” (γενναῖον ψεῦδος). (shrink)

Grenon and Smith (2004) propose a framework for the ontology of things in space and time involving and invoking the distinction between continuants and occurrents, which has become a key element of Basic Formal Ontology (BFO). The terminology of SNAP (from “snapshot:” state of a continuant at a time) and SPAN (how an occurrent develops over an interval or timespan) occurs in that paper’s title. While any commonsense ontology will have a place for both continuants and occurrents, there is much (...) room for philosophical debate on whether one of them is more basic than the other, or can be reduced to the other, or whether they are equally fundamental, or whether they are two different perspectives on the same reality. Grenon and Smith opt for the last of these. They call the accounts of continuants (SNAP) and occurrents (SPAN) both “ontologies.” They do not have a single ontology of all that is in space and time. This dialog throws a few of the common arguments around a bit and comes to no sure conclusion. But one of the characters bears a faint resemblance to a certain Buffalonian philosopher. (shrink)

The present paper has two, interrelated objectives. The first is to analyze the different senses in which arguments are characterized as persuasive in the extant writings of Sextus Empiricus. The second is to examine the Pyrrhonist’s therapeutic use of arguments in the discussion with his Dogmatic rivals – more precisely, to determine the sense and basis of Sextus’ distinction between therapeutic arguments that appear weighty and therapeutic arguments that appear weak in their persuasiveness.

This paper aims at resolving a puzzle about the persuasiveness of bootstrapping. On the one hand, bootstrapping is not a persuasive method of settling questions about the reliability of a source. On the other hand, our beliefs that our sense apparatus is reliable is based on other empirically formed beliefs, that is, they are acquired via a presumably complex bootstrapping process. I will argue that when we doubt the reliability of a source, bootstrapping is not a persuasive method for coming (...) to believe that the source is reliable. However, when being initially unaware of a source and its reliability, as in the case of forming beliefs about our sense apparatus, bootstrapping can be eventually persuasive. (shrink)

Psychological studies on fictional persuasion demonstrate that being engaged with fiction systematically affects our beliefs about the real world, in ways that seem insensitive to the truth. This threatens to undermine the widely accepted view that beliefs are essentially regulated in ways that tend to ensure their truth, and may tempt various non-doxastic interpretations of the belief-seeming attitudes we form as a result of engaging with fiction. I evaluate this threat, and argue that it is benign. Even if the (...) relevant attitudes are best seen as genuine beliefs, as I think they often are, their lack of appropriate sensitivity to the truth does not undermine the essential tie between belief and truth. To this end, I shall consider what I take to be the three most plausible models of the cognitive mechanisms underlying fictional persuasion, and argue that on none of these models does fictional persuasion undermine the essential truth-tie.

Narrative representations can change our moral actions and thoughts, for better or for worse. In this article, I develop a theory of fictions' capacity for moral education and moral corruption that is fully sensitive to the diversity of fictions. Specifically, I argue that the way a fiction influences our moral actions and thoughts importantly depends on its genre. This theory promises new insights into practical ethical debates over pornography and media violence.

Faith is the highest truth that ensures the happiness and salvation of man in the world and in the Hereafter. But the essence of superstitious is invalid and wrong. The realization of this happiness and salvation is possible by having a true faith. Another consequence of the true faith is the ability to recognize that this belief is right. Believing in true faith, ensures rightness and makes possible to prove and disclose this truth. It is important to have true faith (...) and accurate affirmation. This certainty requires certain criteria for accuracy and precision. In addition, this situation involves advocating the faith and delivering it to other people. This is closely related to the recognition and proof of these truths. It also makes it necessary to explore the distinction between presumption and believing as well as knowledge and ignorance. It requires examination of the concepts of certainty, doubt, evidence, persuasion and proof and what they have implied in terms of faith. The examination of the proofs of faith in terms of persuasion and proof also increases the understanding of the certainty of a belief. (shrink)

Every day, millions of people use mobile phones, play video games and surf the Internet. It is thus important to determine how technologies like these change what people think and how they behave. This is a central issue in the study of persuasive technologies. ‘Persuasive technologies’—henceforth ‘PTs’—are digital technologies, such as mobile apps, video games and virtual reality systems, that are deployed for the explicit purpose of changing attitudes and/or behaviours, without using coercion, deception or extreme forms of psychological manipulation (...)

‘Philosophical dialogue’ indicates both a form of philosophical inquiry and its corresponding literary genre. In its written form, it typically features two or more characters who engage in a discussion concerning morals, knowledge, as well as a variety of topics that can be widely labelled as ‘philosophical’. Our philosophical dialogue takes place in Krakow, Poland. It is a rainy morning and two strangers are waiting at a tram stop. One of them is dressed neatly, and cannot stop fidgeting (...) with his closed umbrella. The other was caught unprepared by the morning downpour and water is dripping from his worn, soaked jacket.

What do our reactive attitudes towards perceived moral infractions truly represent? According to Gary Watson, Peter Strawson argues that agents can become exempted from negative or positive reactive attitudes under type 2 pleas. These are conditions wherein we might not consider the agent to qualify for moral judgement based on certain biological, cognitive or psychological traits that they might exhibit. Gary Watson feels that this account is not conclusive, that it does not fully represent the inhibition of a moral demand (...) that we might place on an agent. He feels that a better account considers whether or not the agent is a proper object for the moral demands that we might place on him. In this paper I question whether or not Watson's reading of Strawson based on his paper entitled "Freedom and Resentment" is a full account of his argument. I respond by arguing that a critical feature of Strawson's paper that is missing is that of a concern we might have of our own wellbeing whenever we consider another's actions. I argue that more than any perceived rightness or wrongness of another's actions, we worry about the what effects their actions will have in our lives. I believe that this is a sentiment that is missing in Watson's response to Strawson. (shrink)

Douglas Walton’s multitudinous contributions to the study of argumentation seldom, if ever, directly engage with argumentation in mathematics. Nonetheless, several of the innovations with which he is most closely associated lend themselves to improving our understanding of mathematical arguments. I concentrate on two such innovations: dialogue types (§1) and argumentation schemes (§2). I argue that both devices are much more applicable to mathematical reasoning than may be commonly supposed.

Interpretations of Kant’s account of the forms of “taking-to-be-true” (Fürwahrhalten) have generally focused on three such forms: opinion (Meinung), belief (Glaube), and knowledge (Wissen). A second distinction that has received comparatively less attention is that between conviction (Überzeugung) and persuasion (Überredung). Kant appears to use the distinction between the subjective and the objective sufficiency of a taking-to-be-true to characterize all of these forms. However, it is impossible to account for the differences between them by relying on this latter distinction (...) alone. In turn, this makes it difficult to fit all of these forms into a single classification of taking-to-be-true. In this chapter, I propose a new approach to conviction and persuasion that dissolves these problems. Conviction and persuasion are not single forms of taking-to-be-true with distinctive characteristics, yet it is not useful to treat them as “classes” of taking-to-be-true either. Rather, they are “operators” that determine whether a taking-to-be-true is apt or inapt, depending on whether it rests on a correct evaluation of the grounds we have. (shrink)

That bootstrapping and Moorean reasoning fail to instantiate persuasive argumentation is an often informally presented but not systematically developed view. In this paper, I will argue that this unpersuasiveness is not determined by principles of justification transmission but by two straightforward principles of rationality, understood as a concept of internal coherence. First, it is rational for S to believe the conclusion of an argument because of the argument, only if S believes sufficiently many premises of the argument. Second, if S (...) doubts that a source _O_ is reliable and believes that information _i_ is delivered by _O_, then S rationally suspends judgment about the truth of _i_. This paper aims to accomplish two tasks. First, it provides a thorough analysis of why bootstrapping argumentation is not an instance of rational persuasion. Second, it contains a more general theory about preconditions and limits of persuasive argumentation. (shrink)

This paper aims to reconstruct the politico-philosophical content of the Ancient Wenzi, according to three interrelated questions: How does the text communicate its views to the reader? What are its main ideas? When and where were these ideas first put to writing? Accordingly, after a discussion of preliminaria in section 1, section 2 focuses on the rhetorical devices in the text, section 3 on its key terms, and section 4 on its possible historical context. The goal of this paper is (...) not only to describe the content of the Ancient Wenzi, but also to contextualize it. That is, to explore the debate to which the Ancient Wenzi may have responded.

I end the paper by asking what our attitude to (...) the theory should be if there is no existing argument for it. (shrink)

In her paper “Democracy, Public Policy, and Lay Assessments of Scientific Testimony” Elizabeth Anderson (2011) identifies a tension between the requirements of responsible public policy making and democratic legitimacy. The tension, put briefly, is that responsible public policy making should be based on the best available scientific research, but for it to be democratically legitimate there must also be broad public acceptance of whatever policies are put in place. In this chapter I discuss this tension, with a strong focus on (...) the issue of climate change. My aims are twofold. First, I argue that the tension is harder to resolve than Anderson supposes because some ways of securing acceptance for science-based policies will themselves be democratically illegitimate. Second, I take a closer look at the role intellectual autonomy plays in the tension. Many think that what I call “science marketing” methods for securing broad(er) acceptance of scientific claims are illegitimate because they infringe on our intellectual autonomy. I argue that it is less clear that this is true than many suppose. This is because, put roughly, judicious use of targeted science marketing methods need not stop us from developing the ability to think about scientific issues for ourselves. In fact, they may even aide us in developing this ability. While this doesn’t quite resolve the tension identified by Anderson, it does some of the necessary groundwork for resolving it. (shrink)

Dmitri Nikulin is one of the few contemporary philosophers to have devoted books to the topic of dialogue and the dialogical self, especially in the last fifteen years. Yet his work on dialogue and the dialogical has received scant attention by philosophers, and this neglect has hurt the ongoing development of contemporary philosophical work on dialogicality. I want to address this lacuna in contemporary philosophical scholarship on dialogicality and suggest that, although Nikulin’s account is no doubt insightful and (...) thought-provoking, it is problematic for two main reasons: first, his account fails to recognize the proper relationship between dialogue and agency; and second, his enumeration of the necessary and sufficient conditions for dialogue contains conceptual inconsistencies.

The development of personal technologies has recently shifted from devices that seek to capture user attention to those that aim to improve user well-being. Digital wellness technologies use the same attractive qualities of other persuasive apps to motivate users towards behaviors that are personally and socially valuable, such as exercise, wealth-management, and meaningful communication. While these aims are certainly an improvement over the market-driven motivations of earlier technologies, they retain their predecessors’ focus on influencing user behavior as a primary metric (...) of success. Digital wellness technologies are still persuasive technologies, and they do not evade concerns over whether their influence on users is ethically justified. In this paper, we describe several ethical frameworks with which to assess the justification of digital wellness technologies’ influence on users. We propose that while some technologies help users to complete tasks and satisfy immediate preferences, other technologies encourage users to reflect on the values underlying their habits and teach them to evaluate their lives’ competing demands. While the former approach to digital wellness technology is not unethical, we propose that the latter approach is more likely to lead to skillful user engagement with technology. (shrink)

Political polarization is on the rise, undermining the shared space of public reason necessary for a thriving democracy and making voters more willing than ever to dismiss the perspectives of their political opponents. This destructive tendency is especially problematic when it comes to issues of race and gender, as informed views on these topics necessarily require engaging with those whose experiences may differ from our own. In order to help our students combat further polarization, we created a course on "The (...) Philosophy of Race, Class, and Gender" that incorporated intergroup dialogues - small, diverse, semester-long discussion groups-that focused on building the civic virtues of toleration, egalitarianism, and solidarity. In this article, we describe our approach, including the evidence that intergroup dialogue can act as a catalyst for democratic dialogue. We hope that the practice of intergroup dialogue can help other instructors cultivate the civic virtues in their philosophy classrooms as well. (shrink)
