This essay examines the Brazilian deforestation debate to explicate the beginnings of a post-modern theory of argumentation. Modernist argumentation reflects two distinct approaches, found in the deforestation controversy. The first approach, ‘universal minimilization,’ presumes that the survival of humanity is sufficient grounds upon which to base argument. The alternative, ‘strategic manipulation,’ results in argument being employed as a technical device to advance one's interest. In place of the modernist approach, we offer an ecocentric theory of argumentation. This conception calls for (...) individuals to set aside differences in values to sustain humanity but at the same time to be sensitive to differences in costs and benefits that accrue from common efforts to persons differently situated. Additionally, this view operates with a tacit working assumption that environmental questions are not discrete entities to be evaluated separately. Rather, people must act collectively on a range of interconnected issues to ensure survival. (shrink)

This paper presents the results of computer simulations with a community of actors playing a large number of voluntarily iterated two-person-PD. The simulations are designed to enable uncooperative actors to exploit partners, leave them and find a new partner who knows nothing about their previous behavioral history. Hit-and-run exploitation should thrive under these conditions. However, as Schuessler (1989; 1990) has shown, the setting is highly unfavorable to uncooperative players. The present study extends this result to a wider set of strategies (...) which can alternatively stay with defectors {and try to improve them) or leave them quickly. In addition, a class of seemingly clever strategies is introduced which try to exploit the expected dynamics of looking for a partner. Still, a high amount of egoistical cooperation can persist in the present scenario. (shrink)

This paper is taken from a long section of the _Tattva-cintā-maṇi_ by Gaṅgeśa that is devoted to proving the existence of—to use an inadequate word—“God” in a somewhat minimalist sense. The _īśvara_, the “Lord,” is for Gaṅgeśa, following Nyāya predecessors, a divine agent, a self, responsible for much, not all, of the order in the world. Unseen Force, _adṛṣṭa_, which is in effect _karman_ made by human action, is also a powerful agent as well as things’ intrinsic natures. Moreover, ordinary (...) selves, atoms, ether, and universals are uncreated. But the _īśvara_ brings about just desert in reincarnation in actualizing Unseen Force, and is responsible for a broad swathe of what some see as accidental arrangements as well as the forming of the macro elements from eternal, naturally _dis_joined atoms. Thus the cosmos in its general existence and structure is viewed in Nyāya as the work of the Lord. Gaṅgeśa’s argument runs: Earth and the like [_a_ (_pakṣa_) = earth and the like (_kṣity-ādi_)] have a conscious agent as a cause [S (_sādhya_) = having an agential cause (_sakartṛkatva_) (S_a_)], _since_ they are effects [H (_sādhana_) = being an effect [(_kāryatva_) (H_a_)], like a pot [_b_ (_dṛṣṭānta_) = a pot (H_b_,S_b_)]. And so the _vyāpti_ rule is: [H → S (_vyāpti_)] Whatever is an effect has an agential cause. For earth and the like, it is reasoned that only an omniscient _īśvara_ could be that cause. The argument was a target of Buddhists who pointed to counterexamples such as growing grass. Growing grass exhibits the prover property, being-an-effect, but not the property to be proved, having-an-agential-cause. The long section is dominated by Gaṅgeśa’s rebutting this and other potential defeaters, in particular, the _upādhi_, having-a-living-body (God does not have a living body but all the agential causes with which we are familiar do), along with a counterinference (_sat-pratipakṣa_), I_a_ & (x)(Ix → ¬Sx), where I = not-produced-by-an-agent-with-a-body.

Keith Donnellan’s distinction between the attributive and referential uses of definite descriptions has spurred debates regarding the truth conditions of the utterance “the F is G” with definite descriptions used referentially. In this article, I present a semantic account of referential descriptions, grounded in the contextual factors of the utterance, including the speaker’s intention and presupposition as well as the interlocutor’s recognition of them. This account is called the IPR-semantic account, according to which the speaker’s intention (I), presupposition (P), and (...) the interlocutor's recognition (R) jointly determine whether “the F” in an utterance “the F is G” is used referentially or attributively, and the meaning of “the F” is determined by whether it is used referentially or attributively. Moreover, I argue that the meaning of the referential description “the F” is the intended object e, embodied with a property H that has prompted the speaker to presuppose that e is F and to intend to use “the F” to refer to e, as well as the interlocutor to recognize the presupposition and intention. According to the IPR-semantic account, the utterance “the F is G” with “the F” used referentially expresses a singular proposition, namely, that e is G, and it is true if and only if the intended object e is G. Additionally, I argue that the IPR-semantic account not only surpasses some alternative semantic accounts but also outperforms Kripke’s pragmatic account. (shrink)

IntroductionElements mark the reality of reading the female body in symbolic constructions and social symbols in the exercise of their reproductive health. The study aims to identify elements that characterize the female condition while analyzing the reproductive health of Brazilian and French women.Materials and MethodsA qualitative, multicenter, international study was conducted in Brazil and in France between 2016 and 2019. Data were produced through the use of semi-structured scripts. Focus group discussions and individual interviews were conducted with women who (...) gave birth, hetero-female couples who lived the experience of gestation and birth of a baby, and professionals of maternal and childcare services or members of the associations concerned with the health of mothers and babies. It was guided by the theoretical-methodological framework of institutional analysis in line with the French Institutional Socioclinics.ResultsSexual and reproductive health in the realities researched in Brazil and France are sometimes close and sometimes far apart. In what involves the Brazilian health system, abortion is criminalized and often performed illegally. Furthermore, pregnancy, childbirth, and the postpartum period are highly medicalized. In addition, childbirth is not assured as an experience for a woman and her family. This aspect is confirmed by high numbers of cesarean sections performed or by maternal and infant mortality indicators. The French health system prioritizes vaginal deliveries and seems to assure more autonomy to women, but at the same time, it is worn out by the logic of profit, the efficiency of actions, and the rationalization of practices. In association with these, there are other intrinsic elements in the functioning of the institution that delineates the format of each country: notion of women's rights, violence against women, and discussion regarding the oppression markers of race, gender, sexuality, and social class.ConclusionsBoth countries reveal aspects related to the social role of women's bodies. The established logic reflects in the decision to have children, motherhood, women's autonomy over their own bodies, and in the core values linked to the termination of pregnancy and the professional practices developed in prenatal care, childbirth, and postpartum.

I consider three challenges to the traditional view according to which moral responsibility involves an epistemic condition in addition to a freedom condition. The first challenge holds that if a person performs an action A freely, then she thereby knows that she is doing A. The epistemic condition is thus built into the freedom condition. The second challenge contends that no epistemic condition is required for moral responsibility, since a person may be blameworthy for (...) an action that she did not know was wrong. The third challenge invokes the quality of will view. On this view, a person is blameworthy for a wrong action just in case the action manifests a bad quality of will. The blameworthy person need not satisfy an additional epistemic condition. I will argue that contrary to appearances, none of these challenges succeeds. Hence, moral responsibility does require a non-superfluous epistemic condition. (shrink)

Oppression and the Human Condition is both a valuable teaching tool and an insightful addition to scholarship on the philosophy of Jean-Paul Sartre. Students and teachers will find it an excellent and accessible introduction to Sartre's existentialism, ideal for courses in existentialist and 20th century philosophy. Equally, Sartre scholars will find that the book, especially the sections on oppression and "bad faith," gives them much to think about. Author Thomas Martin applies Sartre's philosophy to contemporary issues and concerns, (...) and draws on two case studies to make his point. The cases examine modern-day oppressors--in one case an anti-semite, in the other a sexist who objectifies women--in the context of Sartre's "bad faith." The case studies also reinforce Martin's argument that Sartre's early philosophy, especially his concept of "bad faith," provides a framework for discussions of oppressions such as racism and sexism.

Clinical research with children generates special ethical concern, raising the need for additional protections beyond those for research with competent adults. Most guidelines permit research with children when it offers a prospect of direct benefit, or poses minimal risk. Unlike many other guidelines, the U.S. federal regulations also allow institutional review boards to approve pediatric research that does not offer a prospect of direct benefit when the risks are no greater than a minor increase over minimal risk. To approve research (...) in this category, IRBs must find that two additional conditions obtain:1). The intervention or procedure presents experiences to subjects that are reasonably commensurate with those inherent in their actual or expected medical, dental, psychological, social, or educational situations; and 2). The intervention or procedure is likely to yield generalizable knowledge about the subjects disorder or condition which is of vital importance for the understanding or amelioration of the subjects disorder or condition.

New discoveries are improving the odds of human cells surviving in host animals, prompting regulatory and funding agencies to issue calls for additional layers of ethical oversight for certain types of human–animal chimeras. Of interest are research proposals involving chimeric animals with humanized brains. But what is motivating the demand for additional oversight? I locate two, not obviously compatible, motivations, each of which provides the justificatory basis for paying special attention to different sets of human–animal chimeras. Surprisingly, the sets of (...) animals that actually get flagged for special scrutiny by research and funding guidelines do not correlate with either of the sets of animals that arise when we think about what is motivating additional oversight. What this shows is that existing research policies and funding guidelines are disconnected from their motivation: the rationale for flagging certain types of human–animal chimeras as requiring special oversight is ignored in execution.

This paper (based on joint work with M.J.Schervish and J.B.Kadane) discusses some differences between the received theory of regular conditional distributions, which is the countably additive theory of conditional probability, and a rival theory of conditional probability using the theory of finitely additive probability. The focus of the paper is maximally "improper" conditional probability distributions, where the received theory requires, in effect, that P{a: P(a|a) = 0} = 1. This work builds upon the results of Blackwell and Dubins (1975).

This paper dwells upon formal models of changes of beliefs, or theories, which are expressed in languages containing a binary conditional connective. After defining the basic concept of a (non-trivial) belief revision model. I present a simple proof of Gärdenfors''s (1986) triviality theorem. I claim that on a proper understanding of this theorem we must give up the thesis that consistent revisions (additions) are to be equated with logical expansions. If negated or might conditionals are interpreted on the basis of (...) autoepistemic omniscience, or if autoepistemic modalities (Moore) are admitted, even more severe triviality results ensue. It is argued that additions cannot be philosophically construed as parasitic (Levi) on expansions. In conclusion I outline somed logical consequences of the fact that we must not expect monotonic revisions in languages including conditionals. (shrink)

In recognition of the central place that the concept of tragedy holds in the historical understanding of culture and society, this paper features an analysis of its presence, current state, and value in the digital environments of the postmodern era, with special attention to videogames. Thus, the overcoming of a classic model of tragedy in the cybertextual condition is first determined, along with the discursive dimension underlying said overcoming. To this end a theoretical statement to the issue of tragedy (...) is proposed, from the perspective of the cybertext as procedural rhetoric. This will establish the formulation of a semiotic analytical model that problematizes Greimas’ actantial system under the light of the digital and interactive reality of videogames. To avoid this constraint, we propose to attach a new variable to the base of the generative trajectory: the “configurative synthesis,” product of the so-called “gaming/playing function.” This addition will integrate the figures of the game and the player in the dynamic distinction of the “quasi-Actant.” Finally, a sample of 79 cases will be observed in regards to the implications of the cybertextual notion of tragedy to the narrative and discourse of videogames.

We examine two competing effects of beliefs on conditional inferences. The suppression effect occurs for conditionals, for example, “if she watered the plants they bloomed,” when beliefs about additional background conditions, for example, “if the sun shone they bloomed” decrease the frequency of inferences such as modus tollens (from “the plants did not bloom” to “therefore she did not water them”). In contrast, the counterfactual elevation effect occurs for counterfactual conditionals, for example, “if she had watered the plants they would (...) have bloomed,” when beliefs about the known or presupposed facts, “she did not water the plants and they did not bloom” increase the frequency of inferences such as modus tollens. We report six experiments that show that beliefs about additional conditions take precedence over beliefs about presupposed facts for counterfactuals. The modus tollens inference is suppressed for counterfactuals that contain additional conditions (Experiments 1a and 1b). The denial of the antecedent inference (from “she did not water the plants” to “therefore they did not bloom”) is suppressed for counterfactuals that contain alternatives (Experiments 2a and 2b). We report a new “switched‐suppression” effect for conditionals with negated components, for example, “if she had not watered the plants they would not have bloomed”: modus tollens is suppressed by alternatives and denial of the antecedent by additional conditions, rather than vice versa (Experiments 3a and 3b). We discuss the implications of the results for alternative theories of conditional reasoning. (shrink)

In this article I discuss various possible ways of understanding the character of and relations between legal systems in the European Union. In particular, I consider whether there is an EU legal system distinct from and in addition to the national legal systems of EU Member States, or whether it is better to conceive of EU law merely as an aspect of Member States’ legal systems, or indeed whether we should think of there being but a single EU legal (...) system of which Member States’ “national legal systems” are in some sense sub-systems.Resumen:Este artículo discute varios modos posibles de comprender el carácter de los sistemas jurídicos de la Unión Europea y sus relaciones.

In the last third of the twentieth century, humanists and social scientists argued that attention to genetics would heighten already‐existing genetic determinism, which in turn would intensify negative social outcomes, especially sexism, racism, ableism, and harshness to criminals. They assumed that laypeople are at risk of becoming genetic essentialists. I will call this the “laypeople are genetic essentialists model.” This model has not accurately predicted psychosocial impacts of findings from genetics research. I will be arguing that the failure of the (...) model can be traced to its inability to recognize the complexity of laypeople’s attitudes; its incorrect theory of how beliefs, attitudes, and discourse function; and its blindness to how academics’ own interests can override the available evidence. More specifically, I suggest that the substantial data about laypeople’s deployment of genetics supports what I will call the “laypeople are strategic essentialists model” better than the “laypeople are genetic essentialists model.” The strategic essentialists model holds that people tend to store multiple categories, including multiple causal forces, that they deploy “strategically” to serve context‐dependent goals. It will be difficult for academics to reorient ourselves to model laypeople as sophisticated strategic essentialists rather than as naïve genetic essentialists. Perhaps a little shift, however, will be of value. (shrink)

In the longstanding foundational debate whether to require that probability is countably additive, in addition to being finitely additive, those who resist the added condition raise two concerns that we take up in this paper. (1) _Existence_: Settings where no countably additive probability exists though finitely additive probabilities do. (2) _Complete Additivity_: Where reasons for countable additivity don’t stop there. Those reasons entail complete additivity—the (measurable) union of probability 0 sets has probability 0, regardless the cardinality of that (...) union. Then probability distributions are discrete, not continuous. We use Easwaran’s (Easwaran, Thought 2:53–61, 2013) advocacy of the _Comparative_ principle to illustrate these two concerns. Easwaran supports countable additivity, both for numerical probabilities and for finer, qualitative probabilities, by defending a condition he calls the _Comparative_ principle [ \({\mathcal{C}}\) ]. For numerical probabilities, principle \({\mathcal{C}}\) contrasts pairs, P 1 and P 2, defined over a common partition \(\prod\) = {a _i_ : _i_ ∈ I} of measurable events. \({\mathcal{C}}\) requires that no P 1 may be pointwise dominated, i.e., no (finitely additive) probability P 2 exists such that for each _i_ ∈ I, P 2 (a _i_ ) > P 1 (a _i_ ). By design, the cardinality of \(\prod\) is not limited in \({\mathcal{C}}\), which Easwaran asserts is important when arguing that the principle does not require more, or less, than that probability is countably additive. We agree that a numerical probability P satisfies principle \({\mathcal{C}}\) in all partitions just in case P is countably additive. However, we show that for numerical probabilities, by considering the size of the algebra of events to which probability is applied, principle \({\mathcal{C}}\) is subject to each of the above concerns, (1) and (2). Also, Easwaran considers principle \({\mathcal{C}}\) with non-numerical, qualitative probabilities, where a qualitative probability may be finer than an almost agreeing numerical probability P. A qualitative probability is regular if possible events are strictly more likely than impossible events. Easwaran motivates and illustrates regular qualitative probabilities using a continuous, almost agreeing quantitative probability that is uniform on the unit interval. We make explicit the conditions for applying principle \({\mathcal{C}}\) with qualitative probabilities and show that \({\mathcal{C}}\) restricts regular qualitative probabilities to those whose almost agreeing quantitative probabilities are completely additive. For instance, Easwaran’s motivating example of a regular qualitative probability is precluded by principle \({\mathcal{C}}\). (shrink)

In the face of documented difficulties in the public understanding of genetics, new metaphors have been suggested. The language of information coding and processing has become deeply entrenched in the public representation of genetics, and some critics have found fault in the blueprint metaphor, a variant of the dominant theme. They have offered the language of the recipe as a preferable metaphor. The metaphors of the blueprint and the recipe are compared in respect to their deterministic implications and other associations. (...) The likelihood of the recipe metaphor framing cognition in more useful ways is called into question. (shrink)

The Swamping Problem is one of the standard objections to reliabilism. If one assumes, as reliabilism does, that truth is the only non-instrumental epistemic value, then the worry is that the additional value of knowledge over true belief cannot be adequately explained, for reliability only has instrumental value relative to the non-instrumental value of truth. Goldman and Olsson reply to this objection that reliabilist knowledge raises the objective probability of future true beliefs and is thus more valuable than mere true (...) belief. I argue against their proposed solution to the Swamping Problem that the conditional probability of future true beliefs given knowledge is not clearly higher than given mere true belief. (shrink)

ABSTRACT “Lockdown!” has articulated our collective and individual fear response to the novel coronavirus. Two regnant specialized discourses fostered by the academy—science and ideology critique—could not redirect this inadequate response nor generate their own adequately broad and focused social responses. This suggests the desirability of the academy adding phronesis as a goal for its pedagogical practices.

Anorexia nervosa remains an enigma among Western cultures. Various causal explanations have been offered, encompassing biological, psychological, and sociocultural models. These explanations, however, focus on the immediate or proximal mechanisms of causation. A more thorough understanding of anorexia nervosa can be achieved by understanding the relationship between these factors and ultimate causation, the level of explanation which deals with individual reproductive fitness. This paper reviews the biological, psychological, sociocultural, and evolutionary models and indicates a necessary synthesis between proximate and ultimate (...) levels of causation in examining the anorexia nervosa puzzle.

We study relationships between different aspects of risk preferences. We show that, under the assumptions of non-satiation and bounded marginal utility, some additional conditions on the asymptotic behaviour of the indices of relative prudence and relative temperance ensure that risk aversion, prudence and temperance are equivalent. Similar conclusions are derived for higher-degree risk aversion. Moreover, some links between indices of relative risk aversion of different degrees are derived. The implications of these results for several economic problems which involve risk changes (...) are discussed. (shrink)

The human propensity for casting our social worlds as "us against them" is perhaps the primary impediment to deep and broadly inclusive understandings of the workings of rhetoric. Many decades ago, Kenneth Burke assailed that barrier with regard to Adolf Hitler. Surrounded by the satisfactions of vituperation against the leader of one of the world's most heinous social movements, Burke begged his readers to make space for understanding how Hitler's rhetoric brought about what it did. Philippe-Joseph Salazar's Words Are Weapons (...) makes a similar contribution for our era. He asks us to resist the gratifications generated by dismissing as "Islamaphobic" any critical analysis of what he calls "caliphal"... (shrink)

SummaryIn the first part of the paper necessary conditions for the rationality of the notions of belief, knowledge, and assumption are given: Among the different conditions it is stressed that one needs two different concepts of belief, one such that if someone knows something he also believes it, the other exclusive such that if someone knows something he need not to believe it and if he believes it he does not yet know it. Another important point is that deductive infallibility (...) has to be rejected as not being a property of human rationality. Similarly it is not a property of human rationality to know all logical true statements.The second chapter offers a deductive system which meets these and additional conditions of human rationality. The third chapter contains the semantics of the deductive system.RésuméDans le premier chapitre ľauteur énumére des conditions nécessaires à la rationalité des concepts croire, savoir et admettre.

People respond to metaphors as much with regard to the emotions that they generate as to their referential, comparative contents. Interviews with non-geneticists about preferred metaphors for gene-environment interaction that illustrate this tendency are reported. These interviews also reveal the dynamic tendency of such emotional responses. A second set of interviews shows that lay people may preferentially use a metaphor of "virus" or "disease" for talking about genes, as opposed to the coding metaphors transmitted through the mass media and reportedly (...) preferred by geneticists. An explanation based on the differently situated emotions of these groups is proposed. It is proposed that the prominence of emotions in responding to genetics indicates the importance of incorporating analyses of emotions instead of simple principles into policy formulation about genetics.

In this paper we examine the thesis that the probability of the conditional is the conditional probability. Previous work by a number of authors has shown that in standard numerical probability theories, the addition of the thesis leads to triviality. We introduce very weak, comparative conditional probability structures and discuss some extremely simple constraints. We show that even in such a minimal context, if one adds the thesis that the probability of a conditional is the conditional probability, then one (...) trivializes the theory. Another way of stating the result is that the conditional of conditional probability cannot be represented in the object language on pain of trivializing the theory. (shrink)

In order to resolve the controversial discussion regarding content effects in deductive reasoning, we propose distinguishing between two inferential sources—an argument's form , and additional relations people associate with the argument's content —and analysing their interplay. Both sources are equally necessary in order to understand the role content plays in deductive reasoning. People make valid deductions from the content relations ( content competence ), but in thematic reasoning tasks, these deductions lead to the intriguing phenomenon known as content effects . (...) Focusing on the interplay of both sources of inferences, the dual source distinction enables a novel class of predictions to be made, namely the correct mastery of the logical connectors ( form competence ) in tasks that require the individual to think about an argument's form in relation to its content. To illustrate the dual source approach and its implications, the selection task paradigm of conditional reasoning with a point of view is used in combination with two content domains: conditional promises with cheating and non-cheating perspectives and technical systems with causal perspectives. Experimental findings corroborate all three phenomena: content competence, content effects, and form competence. The dual source distinction is discussed with regard to current theories of reasoning.

Depending on the modality of the argument, memory can be a source of influence from an indeterminate past or a means of reference to the historical conditions of human life. The historic perspective is strongly related to the Enlightenment. Based on recent contributions to the philosophy of technology, which describe thinking in terms of tools and machines as a general human activity, historic memory can be interpreted as a technical approach to the past. Similar to the determinate operations in technology, (...) the references to the past though the exhibits of museums, the contents of archives, and similar means dominate reflection about the past. The mind has to move around them. Nevertheless, they require additional effort to become usable in their function for memory. Technicians illustrate this effort in their role as enablers of tools and machines. Similarly, curators and archivists can be understood as enablers of relation to the past, in museums, archives, etc. The efforts of technicians can be categorized according to different concepts of rationality. In the discussion about memory, the impact of museums, archives, and other enabling circumstances for memory is yet rather unclear. The comparison with technology can serve as an inspiration for further research in this direction. (shrink)

We report two studies on the effect of implicitly versus explicitly conveying affirmation and denial problems about conditionals. Recently Evans and Handley (1999) and Schroyens et al. (1999b, 2000b) showed that implicit referencing elicits matching bias: Fewer determinate inferences are made, when the categorical premise (e.g., B) mismatches the conditional's referred clause (e.g., A). Also, the effect of implicit affirmation (B affirms not-A) is larger than the effect of implicit denial (B denies A). Schroyens et al. hypothesised that this interaction (...) is due to uncertainty in the case-wise affirmation of the contrast class of negated elements involved in implicit affirmations. In Experiment 1 we tested this hypothesis by manipulating the set size of the conditional clauses. The results confirm that binary sets, where the contrast class is a singleton, eliminate the differential effect of implicit affirmation and denial. With non-binary sets the interaction is not modulated by the scope of the contrast class (3, 5, 9 elements). Experiment 2 further investigated the role of contrast classes by using class inclusion to construct implicit affirmations (Mammal vs Mammal or Monkey) and implicit denial (No-Mammal vs Mammal or Monkey), in addition to the standard implicit problems mediated by contrast-class inclusion [(No-)Mammal/No-Mammal; Reptile; Snake). Findings indicate that class inclusion (Mammal/Monkey; Reptile/ Snake) only marginally affects performance, and is independent of the type of problem. This would suggest that the implicitness problem-type interaction is dependent on constructing contrast classes. However, the experiment failed to replicate the interaction, even on the subset of problems repeating the abstract letter/number format of Experiment 1. Moreover, with the natural binary set-sizes (vowels/consonants) the implicitness effect was eliminated entirely. (shrink)

This paper proves that certain supertasks constitute counterexamples to countable additivity even in the frame of an objective (not subjective, à la de Finetti) conception of probability. The argument requires taking conditional probability as a primitive notion.

Inferential or epistemic conditional sentences represent a blueprint of someone’s reasoning process from premise to conclusion. Declerck and Reed (2001) make a distinction between a direct and an indirect type. In the latter type the direction of reasoning goes backwards, from the blatant falsehood of the consequent to the falsehood of the antecedent. We first present a modal reinterpretation in terms of Argumentation Schemes of indirect inferential conditionals (IIC’s) in Declerck and Reed (2001). We furthermore argue for a distinction between (...) epistemic-modal strong and deontic-modal weak IIC’s. In addition, we extend the category of the indirect inferential conditionals in order to include several other deontic-modal subtypes. On the basis of the undesirability of the consequent the hearer in these cases infers that the antecedent is also undesirable. In this way the rhetoric-argumentative strategy of Reductio ad Absurdum is extended from the realm of deductive reasoning to that of practical reasoning. (shrink)
