The article presents a full proof‐theoretic semantics for natural deduction based on an extended inversion principle: the elimination rule for an operator q may invert the introduction rule for q, but also vice versa, the introduction rule for a connective q may invert the elimination rule for q. Such an inversion—extending Prawitz' concept of inversion—gives the following theorem: Inversion for two...
This paper holds the view that although bullshit and obscurantism are obviously related phenomena, they should be kept distinct for conceptual reasons. It shows that whereas phenomena of bullshit tend to concentrate on speech acts and a violation of the expectations of relevance therein, obscurantism betrays an indirect move to confound while promising deep content. After an overview of studies on...
In this paper, I evaluate some recent attacks on Williamson's claim that knowledge is the most general factive stative propositional attitude. Two types of approaches are discussed: The first approach attempts to show that there are factive mental states denoted by factive mental state operators that are not cases of knowing. The second approach aims to show that there are factive mental states that...
In this paper, we bring into focus the level of thought or content in the elucidation of disagreement. We set out the view that disagreement at this level involves a specific form of noncotenability, namely, noncotenability as captured by sense or intension as opposed to reference. We present the challenge that nourishes the alternative referential view and suggest, through examples, that (i) only...
Political philosophy has traditionally been defined as a normative discipline with a distinctively ideal component, largely informed by moral philosophy. In this paper, I investigate a prominent critique of ideal theory specifically with the goal of resituating the debate within a larger framework in the philosophy of science. I then mount a novel case for how ideal theory should be viewed in terms...
In this paper, I reconstruct Immanuel Kant's theory of theoretical and practical error, and I situate it within the broader context of his transcendental philosophy. I thereby refer to his conception of dialectic as the logic of illusion (CpR, B 86) and to his concept of rationalizing. By referring to Donald Davidson's conception of irrationality, I argue that Kant's theory of error allows us to keep...
The aim of this paper is to relate the debate about the status of S4 and S5 as modal logics for metaphysical modality to the debate about the identity of propositions. The necessary truth of the characteristic axioms of S4 and S5 (when interpreted in terms of metaphysical modality) is derived from a view about the identity of propositions, the view that necessarily equivalent propositions are identical.
According to colocationism, two different material objects can be colocated during their entire careers. The typical example is that of a statue and the lump of clay out of which it is made, both of which start to exist and cease to exist at exactly the same time. One of the main problems for colocationism is the grounding problem. Recently, several attractive colocationist answers to the problem...
I explore some surprising results concerning positive individual contributions, focusing on those made in one's job or in the position one holds. The replaceability of most people on the job or in positions of influence threatens our common sense notion of contribution. Two concepts of contribution are distinguished, and help to limit the sense of paradox, but do not completely eliminate it. The ideal...
Many philosophers believe that true belief is of epistemic value, but that knowledge is of even more epistemic value. Some claim that this surplus value is instrumentally valuable to the value of true belief. I call the conjunction of these claims the instrumentalist's conjunction. The so‐called swamping problem is meant to show that instrumentalist's conjunction is inconsistent. Crudely put, the...
Quite a few scholars claim that many implicata are propositions about the speaker's epistemic or doxastic states. I argue, on the contrary, that implicata are generally non‐epistemic. Some alleged cases of epistemic implicature are not implicatures in the first place because they do not meet Grice's non‐triviality requirement, and epistemic implicata in general would infringe on the maxim of quantity...
This paper is an attempt to analyse the concept of literary autonomy, to explore its various manifestations in previous and current theories of literary studies and literary aesthetics, and to fit it into a broad outlook of literature's specificity and uniqueness. It defends the idea of literature's separate identity, however, not at the expense of breaking free of the concept of meaning in the strict...
Epistemic and practical interests are often in conflict. This also occurs in institutional settings such as the legal one. Rule 407 of the U.S. Federal Rules of Evidence is an example of that because it sacrifices some epistemic interests in favour of practical ones. It is the rule on subsequent remedial measures (SRM), which is mainly designed to answer a practical concern (reducing accidents) instead...
It is argued that certain quantum theories of gravity — string theory, loop quantum gravity, non‐commutative field theory — do not include spacetime as part of their fundamental ontology. There is a concern in the literature that theories of this kind are physically opaque and empirically incoherent. In this paper, I clarify and amend Huggett and Wüthrich's argument against these claims. Whereas the...
Gottlob Frege takes logic to be the science of truth throughout his career. However, the mature Frege makes remarks which seem to go against the idea that logic is the science of truth. This paper shows that we can explain away this tension in the mature Frege's conception of logic if we accept that truth is an object, that is, the truth‐vale True qua the reference of a sentence, for Frege. Even though...
