Keefe, Rosanna. What Logical Pluralism Cannot Be
2014, Synthese 191 (7):1375-1390
Expand entry
Added by: Franci Mangraviti
Abstract:

Logical Pluralists maintain that there is more than one genuine/true logical consequence relation. This paper seeks to understand what the position could amount to and some of the challenges faced by its formulation and defence. I consider in detail Beall and Restall’s Logical Pluralism—which seeks to accommodate radically different logics by stressing the way that they each fit a general form, the Generalised Tarski Thesis (GTT)—arguing against the claim that different instances of GTT are admissible precisifications of logical consequence. I then consider what it is to endorse a logic within a pluralist framework and criticise the options Beall and Restall entertain. A case study involving many-valued logics is examined. I next turn to issues of the applications of different logics and questions of which logic a pluralist should use in particular contexts. A dilemma regarding the applicability of admissible logics is tackled and it is argued that application is a red herring in relation to both understanding and defending a plausible form of logical pluralism. In the final section, I consider other ways to be and not to be a logical pluralist by examining analogous positions in debates over religious pluralism: this, I maintain, illustrates further limitations and challenges for a very general logical pluralism. Certain less wide-ranging pluralist positions are more plausible in both cases, I suggest, but assessment of those positions needs to be undertaken on a case-by-case basis.

Comment: Makes for a nice counter in any course discussing Beall and Restall's pluralism. Given that the paper is a direct response, some previous familiarity with the topic is advised.

Kouri Kissel, Teresa. Logical Pluralism from a Pragmatic Perspective
2018, Australasian Journal of Philosophy 96 (3):578-591
Expand entry
Added by: Franci Mangraviti
Abstract:

This paper presents a new view of logical pluralism. This pluralism takes into account how the logical connectives shift, depending on the context in which they occur. Using the Question-Under-Discussion Framework as formulated by Craige Roberts, I identify the contextual factor that is responsible for this shift. I then provide an account of the meanings of the logical connectives which can accommodate this factor. Finally, I suggest that this new pluralism has a certain Carnapian flavour. Questions about the meanings of the connectives or the best logic outside of a specified context are not legitimate questions.

Comment: Can serve as an example of logical pluralism in any philosophy of logic course. Familiarity with the pluralisms of Shapiro and Carnap is helpful for comparison, but is not technically required.

Kouri Kissel, Teresa. Metalinguistic Negotiation and Logical Pluralism
2019, Synthese 198 (Suppl 20):4801-4812
Expand entry
Added by: Franci Mangraviti
Abstract:

Logical pluralism is the view that there is more than one right logic. A particular version of the view, what is sometimes called domain-specific logical pluralism, has it that the right logic and connectives depend somehow on the domain of use, or context of use, or the linguistic framework. This type of view has a problem with cross-framework communication, though: it seems that all such communication turns into merely verbal disputes. If two people approach the same domain with different logics as their guide, then they may be using different connectives, and hence talking past each other. In this situation, if we think we are having a conversation about “ ¬ A”, but are using different “ ¬ ”s, then we are not really talking about the same thing. The communication problem prevents legitimate disagreements about logic, which is a bad result. In this paper I articulate a possible solution to this problem, without giving up pluralism, which requires adopting a notion of metalinguistic negotiation, and allows people to communicate and disagree across domains/contexts/frameworks.

Comment: Fit for any philosophy of logic course touching on either logical disagreement or logical pluralism. Given the short length, it may be naturally paired with a paper attacking logical pluralism as a mere verbal dispute. There are no particular prerequisites, although familiarity with at least one kind of domain-specific pluralism is helpful for context.

Russell, Gillian. Logic isn’t Normative
2020, Inquiry: An Interdisciplinary Journal of Philosophy 63 (3-4):371-388
Expand entry
Added by: Franci Mangraviti
Abstract:

Some writers object to logical pluralism on the grounds that logic is normative. The rough idea is that the relation of logical consequence has consequences for what we ought to think and how we ought to reason, so that pluralism about the consequence relation would result in an incoherent or unattractive pluralism about those things. In this paper I argue that logic isn’t normative. I distinguish three different ways in which a theory – such as a logical theory – can be entangled with the normative and argue that logic is only entangled in the weakest of these ways, one which requires it to have no normativity of its own. I use this view to show what is wrong with three different arguments for the conclusion that logic is normative.

Comment: Appropriate for any course touching on the normativity of logic question. Familiarity with the question and with logical pluralism is helpful, but not required. Could be paired with a defense of normativity for discussion.

Russell, Gillian. Logical Nihilism: Could there be no Logic?
2018, Philosophical Issues, 28: 308-324
Expand entry
Added by: Franci Mangraviti
Abstract:

Logical nihilism can be understood as the view that there are no laws of logic. This paper presents both a counterexample-based argument in favor of logical nihilism, and a way to resist it by using Lakatos' method of lemma incorporation. The price to pay is the loss of absolute generality.

Comment: The paper is appropriate for any course discussing the monism vs pluralism vs nihilism debate in logic (or maybe even focusing on varieties of logical nihilism). On a technical level it requires no more than an introduction to formal logic; some familiarity with monist and pluralist positions is helpful for context.

Added by: Giada Fratantonio and Berta Grimau
Abstract: Description: Survey article on logical pluralism. The article is divided into three main parts: i) in the first one the author presents the main arguments for logical pluralism with respect to logical consequence; ii) in the second part, the author considers the relation between logical pluralism and Carnap's linguistic pluralism; iii) in the last section, the author considers further kinds of logical pluralism.

Comment: This article could be used as background or overview reading on logical pluralism. Suitable for a specialised, perhaps master's level course on logical pluralism or for a more general course on philosophy of logic touching on the topic.

Sereni, Andrea, Sforza Fogliani, Maria Paola. How to Water a Thousand Flowers. On the Logic of Logical Pluralism
2017, Inquiry: An Interdisciplinary Journal of Philosophy:1-24
Expand entry
Added by: Franci Mangraviti
Abstract:

How many logics do logical pluralists adopt, or are allowed to adopt, or ought to adopt, in arguing for their view? These metatheoretical questions lurk behind much of the discussion on logical pluralism, and have a direct bearing on normative issues concerning the choice of a correct logic and the characterization of valid reasoning. Still, they commonly receive just swift answers – if any. Our
aim is to tackle these questions head on, by clarifying the range of possibilities that logical pluralists have at their disposal when it comes to the metatheory of their position, and by spelling out which routes are advisable. We explore ramifications of all relevant responses to our question: no logic, a single logic, more than one logic. In the end, we express skepticism that any proposed answer is viable. This threatens the coherence of current and future versions of logical pluralism.

Comment: Could be used for a lesson on meta-theoretical issues in a course on logical pluralism, or as further reading when discussing logical pluralism in a general course on the philosophy of logic. Some familiarity with the monism/pluralism debate is assumed.

Yap, Audrey. Feminism and Carnap’s Principle of Tolerance
2010, Hypatia 25 (2):437-454

Added by: Franci Mangraviti
Abstract:

The logical empiricists often appear as a foil for feminist theories. Their emphasis on the individualistic nature of knowledge and on the value neutrality of science seems directly opposed to most feminist concerns. However, several recent works have highlighted aspects of Carnap’s views that make him seem like much less of a straight-forwardly positivist thinker. Certain of these aspects lend themselves to feminist concerns much more than the stereotypical picture would imply.

Added by: Franci Mangraviti and Viviane Fairbank
Abstract: I argue that a thoroughgoing naturalized epistemology can easily underestimate the extent to which certain background assumptions will infl uence arguments. Instead, then, I suggest that we can borrow a conceptual tool from neo-Kantian philosophy of science, namely the constitutive a priori. This idea originates in neo-Kantian philosophers who understood, in light of Einsteinian physics, that Kantian views about the a priority of space were untenable. Frameworks that adopt some version of a constitutive a priori take certain propositions to play the role of a priori principles, without granting them the universality or necessity that such principles traditionally hold. I will argue that thinking of certain views or values as having the status of constitutive a priori principles can help us understand what would be required for an epistemic agent to change them, and thus illustrate the extent to which they are resistant to being dislodged by evidence.
