Do Not Revise Ockham's Razor Without Necessity

Ockham's razor asks that we not multiply entities beyond necessity. The razor is a powerful methodological tool, enabling us to articulate reasons for preferring one theory to another. There are those, however, who would modify the razor. Schaffer (2010: 313—our italics), for one, tells us that, ‘I think the proper rendering of Ockham's razor should be ‘Do not multiply fundamental entities without necessity’’. Our aim, here, is to challenge such re‐workings of Ockham's razor.     

Why Ockham’s Razor should be preferred to the Laser

Philosophical Studies - Ockham’s Razor advises us to not multiply entities (or kinds of entities) without necessity. Recently, Jonathan Schaffer and Karen Bennett have argued that we ought to...     

A Jewish Modified Divine Command Theory

We claim that divine command metaethicists have not thought through the nature of the expression of divine love with sufficient rigor. We argue, against prior divine command theories, that the radical difference between God and the natural world means that grounding divine command in divine love can only ground a formal claim of the divine on the human; recipients of revelation must construct particular commands out of this formal claim. While some metaethicists might respond to us by claiming that this account leads to an inability to judge between better and worse constructions of the commanded life, we propose that an analysis of the human response to divine love—theological eros—can be the basis for an articulation of a philosophical theology (in our case, negative theology) that can guide the religious believer toward generating particular principles for ethical action that are grounded in an account of divine action. By linking divine command to imitatio Dei, the believer can have confidence that her imitative acts of God are not inaccurate constructions of the commanded life.     

Neural Synchrony and the Causal Efficacy of Consciousness

The purpose of this paper is to address a well-known dilemma for physicalism. If mental properties are type identical to physical properties, then their causal efficacy is secure, but at the cost of ruling out mentality in creatures very different to ourselves. On the other hand, if mental properties are multiply realizable, then all kinds of creatures can instantiate them, but then they seem to be causally redundant. The causal exclusion problem depends on the widely held principle that realized properties inherit their causal powers from their realizers. While this principle holds for functional realization, it fails on a broader notion of realization that permits the realization of complex qualitative properties such as spatial and temporal patterns. Such properties are best seen as dependent powerful qualities, which have their causal roles in virtue of being the qualities they are, and do not inherit powers from their realizers. Recent studies have identified one such property—neural synchrony—as a correlate of consciousness. If synchrony is also partially constitutive of consciousness, then phenomenal properties are both multiply realizable and causally novel. I outline a version of representationalism about consciousness on which this constitution claim holds.

     

Ontology and logic: remarks on hartry field's anti-platonist philosophy of mathematics

In Science without numbers Hartry Field attempted to formulate a nominalist version of Newtonian physics—one free of ontic commitment to numbers, functions or sets—sufficiently strong to have the standard platonist version as a conservative extension. However, when uses for abstract entities kept popping up like hydra heads, Field enriched his logic to avoid them. This paper reviews some of Field's attempts to deflate his ontology by inflating his logic.     

What Do Easy Inferences Get Us?

In Ontology Made Easy (2015), I defend the idea that there are ‘easy’ inferences that begin from uncontroversial premises and end with answers to disputed ontological questions. But what do easy inferences really get us? Bueno and Cumpa (this journal, 2020) argue that easy inferences don’t tell us about the natures of properties—they don’t tell us what properties are. Moreover, they argue, by accepting an ontologically neutral quantifier we can also resist the conclusion that properties or numbers exist. Here I address these two issues in turn—in ways that help clarify both the scope and results of easy ontology. First, it is important to see that easy inferences were never intended to address modal questions. Modal questions are addressed by a different part of the total deflationary view—modal normativism. So understood, metaphysical modal questions nonetheless do not provide a remaining area for serious metaphysical inquiry. Second, I argue that we have reason to resist adopting an ontologically neutral quantifier, if we aim to answer ontological questions (without begging the question). Addressing these issues helps to clarify both what does (and does not) follow from easy inferences, and how they form part of a larger deflationary metametaphysical view.     

The Powerlessness of Necessity

This paper concerns anti‐Humean intuitions about connections in nature. It argues for the existence of a de re link that is not necessity. Some anti‐Humeans tacitly assume that metaphysical necessity can be used for all sorts of anti‐Humean desires. Metaphysical necessity is thought to stick together whatever would be loose and separate in a Hume world, as if it were a kind of universal superglue. I argue that this is not feasible. Metaphysical necessity might connect synchronically co‐existent properties—kinds and their essential features, for example—but it is difficult to see how it could also serve as the binding force for successions of events. That is, metaphysical necessity seems not to be fit for diachronic, causal affairs in which causal laws, causation, or dispositions are involved. A different anti‐Humean connection in nature has to do that job. My arguments focus mainly on a debate which has been the battleground for Humean vs. anti‐Humean intuitions for many decades—namely, the analysis of dispositional predicates—yet I believe (but do not argue here) that the arguments generalise to causation and causal laws straightforwardly.     

The Pre-reflective Situational Self

It is often held that to have a conscious experience presupposes having some form of implicit self-awareness. The most dominant phenomenological view usually claims that we essentially perceive experiences as our own. This is the so called “mineness” character, or dimension of experience. According to  this view, mineness is not only essential to conscious experience, it also grounds the idea that pre-reflective self-awareness constitutes a minimal self. In this paper, we show that there are reasons to doubt this constituting role of mineness. We argue that there are alternative possibilities and that the necessity for an adequate theory of the self within psychopathology gives us good reasons to believe that we need a thicker notion of the pre-reflective self. To this end, we develop such a notion: the Pre-Reflective Situational Self. To do so, we will first show how alternative conceptions of pre-reflective self-awareness point to philosophical problems with the standard phenomenological view. We claim that this is mainly due to fact that within the phenomenological account the mineness aspect is implicitly playing several roles. Consequently, we argue that a thin interpretation of pre-reflective self-awareness—based on a thin notion of mineness—cannot do its needed job within, at least within psychopathology. This leads us to believe that a thicker conception of pre-reflective self is needed. We, therefore, develop the notion of the pre-reflective situational self by analyzing the dynamical nature of the relation between self-awareness and the world, specifically through our interactive inhabitation of the social world.

     

Heidegger the Metaphysician: Modes‐of‐Being and Grundbegriffe

Modes‐of‐being (Seinsarten) figure centrally in Heidegger's masterwork Being and Time. Testimony to this is Heidegger's characterisation of two of his most celebrated enquiries—the Existential analytic and the Zeug analysis—as investigations into the respective modes‐of‐being of the entities concerned. Yet despite the importance of this concept, commentators disagree widely about what a mode‐of‐being is. In this paper, I systematically outline and defend a novel and exegetically grounded interpretation of this concept. Strongly opposed to Kantian readings, such as those advocated by Taylor Carman and Cristina Lafont, I interpret a mode‐of‐being as a universal that defines a district (Bezirk)—that is, a natural class of entities that ought to be conceptualised in a special way. As such, every mode‐of‐being plays an important metaphysical and epistemic role: serving both to unify a natural class of a high degree of generality and as the interpretandum of an act yielding the basic‐concepts (Grundbegriffe) pertaining to the entities therein. In explicating and arguing for this interpretation, I attribute a characteristically Aristotelian philosophical position to the early Heidegger, encompassing both metaphysical and epistemological realism and a conceptualist theory of universals.     

Are Effect Sizes and Confidence Levels Problems For or Solutions To the Null Hypothesis Test?

Some have proposed that the null hypothesis significance test, as usually conducted using the t test of the difference between means, is an impediment to progress in psychology. To improve its prospects, using Neyman-Pearson confidence intervals and Cohen's standardized effect sizes, d, is recommended. The purpose of these approaches is to enable us to understand what can appropriately be said about the distances between the means and their reliability. Others have written extensively that these recommended strategies are highly interrelated and use identical information. This essay was written to remind us that the t test, based on the sample—not the true—standard deviation, does not apply solely to distance between means. The t test pertains to a much more ambiguous specification: the difference between samples, including sampling variations of the standard deviation.     

WHY WE CANNOT RELY ON OURSELVES FOR EPISTEMIC IMPROVEMENT

There is something very appealing about the idea that we are epistemic agents. One reason—if not the main reason—is that, while we are undoubtedly fallible creatures, us being epistemic agents that do things means that it might just be within our power to improve and thereby do better. One important way in which we would want to improve is in relation to our well‐established tendency for cognitive bias. Still, the proper role of epistemic agency in us avoiding or correcting for cognitive bias is highly limited. In fact, what we know from empirical psychology—particularly with respect to our tendencies for overconfidence—suggests that we cannot rely on ourselves for epistemic improvement, and have good reason to impose significant constraints on our ability to exercise such agency in ameliorative contexts.     

Subjective Situations and Logical Omniscience

The beliefs of the agents in a multi-agent system have been formally modelled in the last decades using doxastic logics. The possible worlds model and its associated Kripke semantics provide an intuitive semantics for these logics, but they commit us to model agents that are logically omniscient. We propose a way of avoiding this problem, using a new kind of entities called subjective situations. We define a new doxastic logic based on these entities and we show how the belief operators have some desirable properties, while avoiding logical omniscience. A comparison with two well-known proposals (Levesque's logic of explicit and implicit beliefs and Thijsse's hybrid sieve systems) is also provided.     

John Stuart Mill,Determinism, and the Problem of Induction

Auguste Comte's doctrine of the three phases through which sciences pass (the theological, the metaphysical, and the positive) allows us to explain what John Stuart Mill was attempting in his magnum opus, the System of Logic: namely, to move the science of logic to its terminal and ‘positive’ stage. Both Mill's startling account of deduction and his unremarked solution to the Humean problem of induction eliminate the notions of necessity or force—in this case, the ‘logical must’—characteristic of a science's metaphysical stage. Mill's treatment had a further surprising payoff: his solution to the Problem of Necessity (what today we call the problem of determinism and freedom of the will).     

Logical Foundations for Belief Representation

This essay presents a philosophical and computational theory of the representation of de re, de dicto, nested, and quasi-indexical belief reports expressed in natural language. The propositional Semantic Network Processing System (SNePS) is used for representing and reasoning about these reports. In particular, quasi-indicators (indexical expressions occurring in intentional contexts and representing uses of indicators by another speaker) pose problems far natural-language representation and reasoning systems, because—unlike pure indicators—they cannot be replaced by coreferential NPs without changing the meaning of the embedding sentence. Therefore, the referent of the quasi-indicator must be represented in such a way that no invalid coreferential claims are entailed. The importance of quasi-indicators is discussed, and it is shown that all four of the above categories of belief reports can be handled by a single representational technique using belief spaces containing intensional entities. Inference rules and belief-revision techniques for the system ore also examined.     

关于克里普克模态性的一个自然主义解释

The Kripkean metaphysical modality (i.e. possibility and necessity) is one of the most important concepts in contemporary analytic philosophy and is the basis of many metaphysical speculations. These metaphysical speculations frequently commit to entities that do not belong to this physical universe, such as merely possible entities, abstract entities, mental entities or qualities not realizable by the physical, which seems to contradict naturalism or physicalism. This paper proposes a naturalistic interpretation of the Kripkean modality, as a naturalist’s response to these metaphysical speculations. It will show that naturalism can accommodate the Kripkean metaphysical modality. In particular, it will show that naturalism can help to resolve the puzzles surrounding Kripke’s a posteriori necessary propositions and a priori contingent propositions. __________ Translated from Zhexue yanjiu 哲学研究 (Philosophical Researches), 2008, (1): 18–26     

Reconsidering the Role of Bridge Laws In Inter-Theoretical Reductions

The present paper surveys the three most prominent accounts in contemporary debates over how sound reduction should be executed. The classical Nagelian model of reduction derives the laws of the target-theory from the laws of the base theory plus some auxiliary premises (so-called bridge laws) connecting the entities of the target and the base theory. The functional model of reduction emphasizes the causal definitions of the target entities referring to their causal relations to base entities. The new-wave model of reduction deduces not the original target theory but an analogous image of it, which remains inside the vocabulary of the base theory. One of the fundamental motivations of both the functional and the new-wave model is to show that bridge laws can be evaded. The present paper argues that bridge laws—in the original Nagelian sense—are inevitable, i.e. that none of these models can evade them. On the one hand, the functional model of reduction needs bridge laws, since its fundamental concept, functionalization, is an inter-theoretical process dealing with entities of two different theories. Theoretical entities of different theories (in a general heterogeneous case) do not have common causal relations, so the functionalization of an entity—without bridge laws—can only be executed in the framework of its own theory. On the other hand, the so-called images of the new-wave account cannot be constructed without the use of bridge laws. These connecting principles are needed to guide the process of deduction within the base theory; without them one would not be able to recognize if the deduced structure was an image of the target theory.     

Proper Names,Contingency A Priori and Necessity A Posteriori

After a brief review of the notions of necessity and a priority, this paper scrutinizes Kripke's arguments for supposedly contingent a priori propositions and necessary a posteriori propositions involving proper names, and reaches a negative conclusion, i.e. there are no such propositions, or at least the propositions Kripke gives as examples are not such propositions. All of us, including Kripke himself, still have to face the old question raised by Hume, i.e. how can we justify the necessity and universality of general statements on the basis of sensory or empirical evidence?     

NONEMPIRICAL REALITY: TRANSCENDING THE PHYSICAL AND SPIRITUAL IN THE ORDER OF THE ONE

I describe characteristic phenomena of quantum physics that suggest that reality appears to us in two domains: the open and well‐known domain of empirical, material things—the realm of actuality—and a hidden and invisible domain of nonempirical, non‐material forms—the realm of potentiality. The nonempirical forms are part of physical reality because they contain the empirical possibilities of the universe and can manifest themselves in the empirical world. Two classes of nonempirical states are discussed: the superposition states of microphysical entities, which are nonempirical because observation destroys them, and the virtual states of material systems, which are nonempirical because they are empty. The non‐empirical part to physical reality represents a predetermined and hidden order that exists before it is empirical, and the visible world is an emanation out of it. I discuss consequences for our understanding of human nature, the origin of life, and human values. Reality is an indivisible wholeness that is aware of its processes, like a Cosmic Spirit, and it reveals its awareness in the mindlike properties of elementary processes as well as in the human consciousness. Thus, one is led to G. W. F. Hegel's thesis that the Cosmic Spirit is thinking in us.     

Conceptual Analysis and Philosophical Naturalism

Entitlement is conceived as a kind of positive epistemic status, attaching to certain propositions, that involves no cognitive or intellectual accomplishment on the part of the beneficiary—a status that is in place by default. In this paper I will argue that the notion of entitlement—or something very like it—falls out of an idea that may at first blush seem rather disparate: that the evidential support relation can be understood as a kind of variably strict conditional (in the sense of Lewis 1973). Lewis provided a general recipe for deriving what he termed inner modalities from any variably strict conditional governed by a logic meeting certain constraints. On my proposal, entitlement need be nothing more exotic than the inner necessity associated with evidential support. Understanding entitlement in this way helps to answer some common concerns—in particular, the concern that entitlement could only be a pragmatic, and not genuinely epistemic, status.     

Command use and compliance in staff communication with elderly residents of long-term care facilities

Verbal communication between nursing assistants and individuals with dementia can be challenging, particularly during hands-on caregiving tasks. Although there are many aspects of verbal communication that can affect the quality of an interaction, one potentially important communication variable is the types of commands issued by nursing assistants when they need a resident to complete a task. The purpose of this study was to examine the kinds of commands used by nursing care staff when they interact with patients with dementia during activities of daily living. Commands were categorized according to their feasibility/specificity as well as form. An additional goal of this study was to measure compliance and noncompliance rates associated with the various categories of commands. Results indicate that alpha commands (clear, concise, and feasible) account for higher compliance and less noncompliance compared with beta commands (ambiguous, interrupted, and not feasible). In addition, commands that are stated directly, that clarify a previous command, and that are repeated exactly produce better compliance. It is concluded that training nursing staff to change the types of commands they provide during caregiving tasks may reduce distress experienced by both staff and residents.
