Abstract: I propose a framework that explicates and distinguishes the epistemic roles of data and models within empirical inquiry through consideration of their use in scientific practice. After arguing that Suppes’ characterization of data models falls short in this respect, I discuss a case of data processing within exploratory research in plant phenotyping and use it to highlight the difference between practices aimed to make data usable as evidence and practices aimed to use data to represent a specific phenomenon. I then argue that whether a set of objects functions as data or models does not depend on intrinsic differences in their physical properties, level of abstraction or the degree of human intervention involved in generating them, but rather on their distinctive roles towards identifying and characterizing the targets of investigation. The paper thus proposes a characterization of data models that builds on Suppes’ attention to data practices, without however needing to posit a fixed hierarchy of data and models or a highly exclusionary definition of data models as statistical constructs.
Logical Self Reference, Set Theoretical Paradoxes and the Measurement Problem in Quantum Mechanics
Introduction: From a logical point of view the measurement problem of quantum mechanics, can be described as a characteristic question of ‘semantical closure’ of a theory: to what extent can a consistent theory (in this case 2R) be closed with respect to the objects and the concepfs which are described and expressed in its metatheory?
Primitive Ontology in a Nutshell
Abstract: The aim of this paper is to summarize a particular approach of doing metaphysics through physics – the primitive ontology approach. The idea is that any fundamental physical theory has a well-defined architecture, to the foundation of which there is the primitive ontology, which represents matter. According to the framework provided by this approach when applied to quantum mechanics, the wave function is not suitable to represent matter. Rather, the wave function has a nomological character, given that its role in the theory is to implement the law of evolution for the primitive ontology.
Platonism and Anti-Platonism: Why Worry?
Abstract: This paper argues that it is scientific realists who should be most concerned about the issue of Platonism and anti-Platonism in mathematics. If one is merely interested in accounting for the practice of pure mathematics, it is unlikely that a story about the ontology of mathematical theories will be essential to such an account. The question of mathematical ontology comes to the fore, however, once one considers our scientific theories. Given that those theories include amongst their laws assertions that imply the existence of mathematical objects, scientific realism, when construed as a claim about the truth or approximate truth of our scientific theories, implies mathematical Platonism. However, a standard argument for scientific realism, the ‘no miracles’ argument, falls short of establishing mathematical Platonism. As a result, this argument cannot establish scientific realism as it is usually defined, but only some weaker position. Scientific ‘realists’ should therefore either redefine their position as a claim about the existence of unobservable physical objects, or alternatively look for an argument for their position that does establish mathematical Platonism.
Epistemicism about vagueness and meta-linguistic safety
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.
Stoic Syllogistic
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.
The Art and Philosophy of George Eliot
Abstract: Much remains to be said about Eliot as a philosopher. I argue that her novels should be understood as attempts to practice philosophy in an alternative key. Her decision to write novels rather than conventional philosophy reflects her desire to actively engage the imaginative and affective, as well as the cognitive, powers of her readers. On her view the imagination grounds our disposition to feel sympathy for our fellow human beings. It is this disposition and its potential for refinement as moral knowledge that she sought to realize in her novels. An appreciation of her philosophical commitments is necessary in order to understand her efforts to construct an immanent ground for moral life. The parts played by the imagination, reason and emotion in the attainment of moral knowledge were of prime concern to both Spinoza and Feuerbach. Each philosopher offered an account of the relations between these capacities and argued for their reformation. This reformative task is one that Eliot attempted in her novels. The radical holism of Spinoza and Feuerbach resonates throughout her work. She had a deep suspicion of dualistic philosophies that separate reason and imagination. Like Spinoza and Feuerbach, she understood these ruptures within our capacities, indeed within our very being, to derive in large part from religion, especially Christianity. The reform of our habitual ways of understanding the world must therefore begin with critical reflection on religion.
Extensionalism and Scientific Theory in Quine’s Philosophy
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.
Avicenna on Possibility and Necessity
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.
Testimonial Smothering and Pornography
Abstract: This paper defends the claim that there are two previously underexplored ways in which pornography silences women. These ways that pornography silences are (1) the smothering of refusal and (2) the smothering of sexual assault reports, and they can be explained in part through Kristie Dotson’s account of “testimonial smothering.” Unlike the work of other writers in the pornography as silencing literature, my discussion of silenced refusal of sex deals with the cases where women have said yes to sex but would have said no if they had felt that they could have. I show that this, and cases where women do not report sexual assault, count as testimonial smothering through identifying rape myths as a species of “pernicious ignorance.” I make the connection to pornography in presenting evidence that pornography contributes to acceptance of rape myths. This takes us to my general conclusion: Dotson’s account of testimonial smothering gives us a way in which pornography contributes to the silencing of women, by silencing their refusal of sex and their reports of sexual assault.
