Cocchiarella’s Formal Ontology and the Paradoxes of Hyperintensionality

This is a critical discussion of Nino B. Cocchiarella’s book “Formal Ontology and Conceptual Realism.” It focuses on paradoxes of hyperintensionality that may arise in formal systems of intensional logic.

From the Middle Out

Agnosticism has been largely passed over in the literature on Theism. This paper lays out an affirmative case for the agnostic position. Tapping into the classical arguments about the paradoxical qualities of ‘omni’ principles it argues that the agnostic position is ultimately more tenable than either Theism or Atheism. In the first part it regards the paradoxes of omnipotence and their replies strictly logically, declaring them to be true antimonies. In the second part it argues that classic arguments for belief before proof run afoul of additional paradoxes and require the rejection of the most basic logical principles to accept.

Idealizations and Concretizations in Laws and Explanations in Physics

The paper tries to provide an alternative to Hempel’s approach to scientific laws and scientific explanation as given in his D-N model. It starts with a brief exposition of the main characteristics of Hempel’s approach to deductive explanations based on universal scientific laws and analyzes the problems and paradoxes inherent in this approach. By way of solution, it analyzes the scientific laws and explanations in classical mechanics and then reconstructs the corresponding models of explanation, as well as the types of scientific laws appearing in it. Finally, it compares this reconstruction with the approaches of J. Woodward and C. Hitchcock, C. Liu and with the views of M. Thalos on analytic mechanics.

Are There Stable Factors in Preadolescent Girls’ Externalizing Behaviors?

Relatively little is known about the factor structure of disruptive behavior among preadolescent girls. The present study reports on exploratory and confirmatory factor analyses of disruptive girl behavior over four successive data waves as rated by parents and teachers in a large, representative community sample of girls (N = 2,451). Five factors were identified from parent ratings (oppositional behavior/conduct problems, inattention, hyperactivity/impulsivity, relational aggression, and callous-unemotional behaviors), and four factors were identified derived from teacher ratings (oppositional behavior/conduct problems/callous-unemotional behaviors, inattention, hyperactivityimpulsivity, and relational aggression). There was a high degree of consistency of items loading on equivalent factors across parent and teacher ratings. Year-to-year stability of factors between ages five and 12 was high for parent ratings (ICC = 0.70 to 0.88), and slightly lower for teacher ratings (ICC = 0.56 to 0.83). These findings are discussed in terms of possible adjustment to the criteria for children's disruptive behavior disorders found in the Diagnostic and Statistical Manual for Mental Disorders.

Plural signification and the Liar paradox

In recent years, speech-act theory has mooted the possibility that one utterance can signify a number of different things. This pluralist conception of signification lies at the heart of Thomas Bradwardine’s solution to the insolubles, logical puzzles such as the semantic paradoxes, presented in Oxford in the early 1320s. His leading assumption was that signification is closed under consequence, that is, that a proposition signifies everything which follows from what it signifies. Then any proposition signifying its own falsity, he showed, also signifies its own truth and so, since it signifies things which cannot both obtain, it is simply false. Bradwardine himself, and his contemporaries, did not elaborate this pluralist theory, or say much in its defence. It can be shown to accord closely, however, with the prevailing conception of logical consequence in England in the fourteenth century. Recent pluralist theories of signification, such as Grice’s, also endorse Bradwardine’s closure postulate as a plausible constraint on signification, and so his analysis of the semantic paradoxes is seen to be both well-grounded and plausible.

Towards a New Epistemology of Mathematics

In this introduction we discuss the motivation behind the workshop “Towards a New Epistemology of Mathematics” of which this special issue constitutes the proceedings. We elaborate on historical and empirical aspects of the desired new epistemology, connect it to the public image of mathematics, and give a summary and an introduction to the contributions to this issue.

Single premise deduction and risk

It is tempting to think that multi premise closure creates a special class of paradoxes having to do with the accumulation of risks, and that these paradoxes could be escaped by rejecting the principle, while still retaining single premise closure. I argue that single premise deduction is also susceptible to risks. I show that what I take to be the strongest argument for rejecting multi premise closure is also an argument for rejecting single premise closure. Because of the symmetry between the principles, they come as a package: either both will have to be rejected or both will have to be revised.

On Promising to Supererogate: A Response to Heyd

In my “Promising and Supererogation” I argue that one cannot fulfill promises to perform supererogatory actions (such as “I hereby promise to perform one supererogatory action every month”). In a response to my paper, David Heyd argues that there is an alternative solution to the problem I raise. While I agree with much that Heyd says about the examples he discusses, his proposed solution involves a crucial alteration of the problem; his proposed solution does not solve the problem I present.

Remarks on Grandi’s Comments

This note is a reply to some of Giovanni Grandi’s comments on my paper “Berkeley’s Contingent Necessities.”

A Conundrum Concerning Creation

In this paper, I expose a conundrum regarding divine creation as Leibniz conceives of such creation. What energizes the conundrum is that the concept of omnibenevolence—“consequential omnibenevolence”—that the Leibnizian argument for the view that the actual world is the best of all possible worlds presupposes, appears to sanction the conclusion that God has no practical reasons to create the actual world.

On what will be: reply to Westphal

Jonathan Westphal’s recent paper attempts to reconcile the view that propositions about the future can be true or false now with the idea that the future cannot now be real. I attempt to show that Westphal’s proposal is either unoriginal or unsatisfying. It is unoriginal if it is just the well-known eternalist solution. It is unsatisfying if it is instead making use of a peculiar, tensed truthmaking principle.

A Further Reply to Beyer on Omniscience

I provide a further response to Jason A. Beyer’s objections to the alleged inconsistency between God’s omniscience and His other attributes.

Public and Private Meaning in Hume: Comments on Ted Morris’ “Meaningfulness without Metaphysics: Another Look at Hume’s Meaning-Empiricism”

This paper raises questions concerning Ted Morris’ interpretation of Hume’s notion of meaning and investigates the private and public aspects of Hume’s notion of meaning.

The Ethics of Academic Journal Editing

This paper amounts to a reply to Professor Donald G. Brown’s thoughtful comment on my “Ethical Issues in Journal Peer-Review”, which appeared in this journal.

The Causal Theory of Perception Revisited

It is generally agreed upon that Grice’s causal theory of perception describes a necessary condition for perception. It does not describe sufficient conditions, however, since there are entities in causal chains that we do not perceive and not all causal chains yield perceptions. One strategy for overcoming these problems is that of strengthening the notion of causality (as done by David Lewis). Another is that of specifying the criteria according to which perceptual experiences should match the way the world is (Frank Jackson and Michael Tye). Finally, one can also try to provide sufficient conditions by elaborating on the content of perceptual experiences (Alva N?e). These different strategies are considered in this paper, with the conclusion that none of them is successful. However, a careful examination of their problems points towards the general solution that we outline at the end.

Top-down influences on attentional capture by color changes

Previous studies have shown that a change in an existing object is not as effective in capturing attention as the appearance of a new object. This view was recently challenged by Lu and Zhou (Psychonomic Bulletin and Review 12:567–572, 2005), who found strong capture effects for an object changing its color. We suspected that this finding critically depends on a procedural particularity in Lu and Zhou’s study, namely that the color of the unique item and the color of the no-unique items randomly switched between trials. In the current study we replicate Lu and Zhou’s capture effect (Experiment 1) and show that no capture occurs when the color-to-stimuli assignment is fixed (Experiment 2). Two further experiments suggest that the capture effect in Experiment 1 is not because the unique item switched color (Experiment 3), but because all the no-unique items switched color (Experiment 4). The results are discussed considering top-down modulation and inter-trial priming effects.

Knowledge as aptness

I raise several objections to Sosa’s account of knowledge as aptness. I argue that aptness is neither necessary nor sufficient for knowledge. I also raise some objection to Sosa’s treatment of dreaming skepticism.

Ontology,matter and emergence

“Ontological emergence” of inherent high-level properties with causal powers is witnessed nowhere. A non-substantialist conception of emergence works much better. It allows downward causation, provided our concept of causality is transformed accordingly.

Seeing Through Technology

In examining representations of cities, disease, and human biology, this paper reflects on what technologies reveal of the conditions to which they’re turned.
