Abstract: The paper challenges Williamson's safety based explanation for why we cannot know the cut-off point of vague expressions. We assume throughout (most of) the paper that Williamson is correct in saying that vague expressions have sharp cut-off points, but we argue that Williamson's explanation for why we do not and cannot know these cut-off points is unsatisfactory. In sect 2 we present Williamson's position in some detail. In particular, we note that Williamson's explanation relies on taking a particular safety principle ('Meta-linguistic belief safety' or 'MBS') as a necessary condition on knowledge. In section 3, we show that even if MBS were a necessary condition on knowledge, that would not be sufficient to show that we cannot know the cut-off points of vague expressions. In section 4, we present our main case against Williamson's explanation: we argue that MBS is not a necessary condition on knowledge, by presenting a series of cases where one's belief violates MBS but nevertheless constitutes knowledge. In section 5, we present and respond to an objection to our view. And in section 6, we briefly discuss the possible directions a theory of vagueness can take, if our objection to Williamson's theory is taken on board.Bobzien, Susanne.

Abstract: For the Stoics, a syllogism is a formally valid argument; the primary function of their syllogistic is to establish such formal validity. Stoic syllogistic is a system of formal logic that relies on two types of argumental rules: (i) 5 rules (the accounts of the indemonstrables) which determine whether any given argument is an indemonstrable argument, i.e. an elementary syllogism the validity of which is not in need of further demonstration; (ii) one unary and three binary argumental rules which establish the formal validity of non-indemonstrable arguments by analysing them in one or more steps into one or more indemonstrable arguments (cut type rules and antilogism). The function of these rules is to reduce given non-indemonstrable arguments to indemonstrable syllogisms. Moreover, the Stoic method of deduction differs from standard modern ones in that the direction is reversed (similar to tableau methods). The Stoic system may hence be called an argumental reductive system of deduction. In this paper, a reconstruction of this system of logic is presented, and similarities to relevance logic are pointed out.Comment: This paper can be used as specialised/further reading for an advanced undergrad or postgraduate course on ancient logic or as a primary reading in an advanced undergrad or postgraduate course on Stoic logic. Alternatively, given that the text argues that there are important parallels between Stoic logic and Relevance logic, it could be used in a course on Relevance logic as well. It requires prior knowledge of logic (in particular, proof theory).

Summary: A comprehensive introduction to ancient (western) logic from the 5th century BCE to the 6th century CE, with an emphasis on topics which may be of interest to contemporary logicians. Topics include pre-Aristotelian logic, Aristotelian logic, Peripatetic logic, Stoic Logic and a note on Epicureans and their views on logic.Comment: This paper would be ideal as an introductory overview for a course on ancient logic. Alternatively, it could serve as an overview for a module on ancient logic within a more general course on the history of logic. No prior knowledge of logic is required; formalisms are for the most part avoided in the paper. Note that this is a SEP entry, so it's completely accessible to students.

Abstract: In this article, I analyze Quine's conception of science, which is a radical defence of extensionalism on the grounds that first?order logic is the most adequate logic for science. I examine some criticisms addressed to it, which show the role of modalities and probabilities in science and argue that Quine's treatment of probability minimizes the intensional character of scientific language and methods by considering that probability is extensionalizable. But this extensionalizing leads to untenable results in some cases and is not consistent with the fact that Quine himself admits confirmation which includes probability. Quine's extensionalism does not account for this fact and then seems unrealistic, even if science ought to be extensional in so far as it is descriptive and mathematically expressible.Comment: This text provide an in-depth overview and critique on Quine's perspective on modality and it would be crucial in postgraduate courses of philosophy of science and logic. Previous knowledge on Quine, modality and quantum mechanics is needed.

Abstract: In this paper, I raise the following problem: How does Avicenna define modalities? What oppositional relations are there between modal propositions, whether quantified or not? After giving Avicenna's definitions of possibility, necessity and impossibility, I analyze the modal oppositions as they are stated by him. This leads to the following results: 1. The relations between the singular modal propositions may be represented by means of a hexagon. Those between the quantified propositions may be represented by means of two hexagons that one could relate to each other. 2. This is so because the exact negation of the bilateral possible, i.e. 'necessary or impossible' is given and applied to the quantified possible propositions. 3. Avicenna distinguishes between the scopes of modality which can be either external (de dicto) or internal (de re). His formulations are external unlike al-F̄ar̄ab̄
;’s ones.
However his treatment of modal oppositions remains incomplete because not all the relations between the modal propositions are stated explicitly. A complete analysis is provided in this paper that fills the gaps of the theory and represents the relations by means of a complex figure containing 12 vertices and several squares and hexagons.Comment: This article is useful for eastern philosophy courses and logic courses. Although the first part provides an accessible introduction to Avicenna's perspective, it would be better for students to have some prior background in logic. This article is useful for eastern philosophy courses and logic courses. Even if in the first part it provides an introductory section on Avicenna's perspective, it would be better to have some pre-esxisting background on this latter one.

Comment: This text is essential for anyone interested in how we define 'sex', 'sexual', or 'sex acts'. It lays out the key difficulties faced in philosophy of sex in a thorough yet accessible and engaging way. Initially a blog post, but since reprinted in philosophy of sex anthologies, it is very easy to read and I recommend setting it as the first reading for a philosophy of sex course.

Publisher's Note: Human genomes are 99.9 percent identical—with one prominent exception. Instead of a matching pair of X chromosomes, men carry a single X, coupled with a tiny chromosome called the Y. Tracking the emergence of a new and distinctive way of thinking about sex represented by the unalterable, simple, and visually compelling binary of the X and Y chromosomes, Sex Itself examines the interaction between cultural gender norms and genetic theories of sex from the beginning of the twentieth century to the present, postgenomic age. Using methods from history, philosophy, and gender studies of science, Sarah S. Richardson uncovers how gender has helped to shape the research practices, questions asked, theories and models, and descriptive language used in sex chromosome research. From the earliest theories of chromosomal sex determination, to the mid-century hypothesis of the aggressive XYY supermale, to the debate about Y chromosome degeneration, to the recent claim that male and female genomes are more different than those of humans and chimpanzees, Richardson shows how cultural gender conceptions influence the genetic science of sex. Richardson shows how sexual science of the past continues to resonate, in ways both subtle and explicit, in contemporary research on the genetics of sex and gender. With the completion of the Human Genome Project, genes and chromosomes are moving to the center of the biology of sex. Sex Itself offers a compelling argument for the importance of ongoing critical dialogue on how cultural conceptions of gender operate within the science of sex.Comment:

Introduction: In increasing numbers, philosophers are coming to read Sellars' "Empiricism and the Philosophy of Mind" (1997, hereafter EPM) as having dealt the definitive death blow to the idea that inner states with epistemic authority could have this authority immediately. EPM purportedly proves that instead, such states necessarily show up already embedded within a web of inferentially articulated conceptual knowledge, and that in order for this to be possible, the epistemic subject must be a negotiator of a normative space in which standards of justification and correctness are already recognized. [...] In this paper I will attempt to show that Sellars' mythical explanations in EPM employ a very specific and rhetorically complex methodology, and likewise that we will not be in a position to critically assess the paper's arguments unless we give careful attention to its overall textual structure and to the nature of the mythical explanations it employs.Comment: A companion to Sellars' ‘Empiricism and the Philosophy of Mind’ for students more inclined to social philosophy.

Summary: Examines the theory of conditionals and whether it's possible to have a unified theory of them.Comment: Great core text as there are many important discussion points here, and Edginton uses lots of helpful examples. Could set students the task of coming up with their own conditionals, and analysing these in the would/will sense. This definitely requires a background in beginner's logic.

Publisher's note: Arguing that traditional feminism is wrong to look to a natural, 'essential' notion of the female, or indeed of sex or gender, Butler starts by questioning the category 'woman' and continues in this vein with examinations of 'the masculine' and 'the feminine'. Best known however, but also most often misinterpreted, is Butler's concept of gender as a reiterated social performance rather than the expression of a prior reality.Comment: All of this book would be very useful for a feminist philosophy course, but chapter 1 in particular would be great to use for a unit on the metaphysics of gender, by considering Butler's account of gender being performative, and how this links in with the social constructivist account of gender.

Magidor, Ofra, Stephen Kearns. Epistemicism about vagueness and meta-linguistic safety
2008, Philosophical Perspectives 22 (1): 277-304.
Comment: This paper would work well as a secondary reading in a course on vagueness with a section on epistemicism. For instance, the course could present Williamson's as the main proposal within that tradition and then turn to this paper for criticism and an alternative proposal within the same tradition.
