Physicalism

According to one conception of strong emergence, strongly emergent properties are nomologically necessitated by their base properties and have novel causal powers relative to them. In this paper, I raise a difficulty for this conception of strong emergence, arguing that these two features are incompatible. Instead of presenting this as an objection to the friends of strong emergence, I argue that this indicates that there are distinct varieties of strong emergence: causal emergence and epiphenomenal emergence. I then explore the prospects (...) of emergentism with this distinction in the background. (shrink)

This article is a philosophical elucidation about the concept of nature in relation to man. The question is not idle: is there something such as nature, or is it only a way of stringing together everything that is not man-made? Given that the ethical, political and instrumental dimension that will be adopted depends on the way in which this concept is constructed. The concept of life is also analyzed. It is concluded that the solutions for biosphere sustainability must be radical (...) and that there is no need to depend on the ghost of our disappearance as a species to make definitive and long-term decisions.

I shall argue in this article that there are certain objectual and methodological boundaries imposed by the nature of physics that all formulations of physicalism based on physical theories should respect. Therefore, empirical physicalism – i.e., the sort of physicalism that is eager to accept all the entities included in some future, ideal and complete physical theory and all entities dependent on them (see Jeffrey Poland and Janice Dowell) – is already committed to the exclusion of certain sorts of entities (...) from its ontological inventory and it is far less tolerant than one might expect. After having presented my argument, I shall describe four plausible boundaries to what can be studied by physics. The boundaries will contribute to constructing a new version of physicalism, i.e., physics physicalism, whose acceptance is entailed by the acceptance of empirical physicalism. Finally, I shall briefly deal with three objections against my strategy and I shall evaluate the consequences of the acceptance of my conclusions for both physicalists and non-physicalists. (shrink)

Discusses and contrasts various accounts of physicalism, naturalism and materialism.

This paper discusses and evaluates a recent argument for the conclusion that an attractive variety of Russellian monism ought to be regarded as a form of physicalism. According to this line of thought, if the Russellian’s “inscrutable” properties are held to ground not only experience, but also the physical structure of the world—and in this sense are not “experience-specific”—they thereby have an unproblematic place in physicalist metaphysics. I argue, in contrast, that there can be a sense in which the Russellian’s (...) inscrutables are experience-specific in a way that a physicalist probably ought to find objectionable, even if they play some role other than grounding experience. This will be the case, I argue, if certain worlds are taken to be possible, as they sometimes have: worlds of “bare structure” and worlds with what might be called “swapped inscrutables”. In this way, I claim that accepting certain possibilities has consequences for how one should understand the nature of the Russellian’s inscrutables and the place they have in physicalist metaphysics.

Article on physicalism and evolutionary explanations.

Life as self-organization is philosophically understood by L. Polo in terms of co-causality between matter, formal configuration and intrinsic efficiency. This characterization provides a dynamic account of life and soul, capable to explain both its identity and its continuous renovation. In this article I especially highlight in this author the metaphysical notions of finality, unity and cosmos, which may be helpful to understand the sense of biological systems in the universe.

If there is a movement or school that epitomizes analytic philosophy in the middle of the twentieth century, it is logical empiricism. Logical empiricists created a scientifically and technically informed philosophy of science, established mathematical logic as a topic in and tool for philosophy, and initiated the project of formal semantics. Accounts of analytic philosophy written in the middle of the twentieth century gave logical empiricism a central place in the project. The second wave of interpretative accounts was constructed to (...) show how philosophy should progress, or had progressed, beyond logical empiricism. The essays survey the formative stages of logical empiricism in central Europe and its acculturation in North America, discussing its main topics, and achievements and failures, in different areas of philosophy of science, and assessing its influence on philosophy, past, present, and future.

Hempel’s Dilemma is a challenge that has to be met by any formulation of physicalism that specifies the physical by reference to a particular physical theory. It poses the problem that if one’s specification of the physical is ‘current’ physical theory, then the physicalism which depends on it is false because current physics is false; and if the specification of the physical is a future or an ideal physics, the physicalism based on it would be trivial as it would be (...) tautologously true, or because very little (if anything at all) can be inferred from or about a physics that does not yet exist. I review the reasons for thinking that the dilemma is a perpetual problem for currentist specifications of the physical, then introduce the argument that the standard positions on the specification question are wanting because they lack a generality which physicalism is generally accepted to have. I end with a suggestion for a way forward for physicalism. (shrink)

Metaphysics has been rejected as nonsense by some philosophers (notably Hume and Ayer) because metaphysical systems cannot be tested empirically. This paper argues that these systems can still usefully be compared by using such criteria as: 1) Scope; 2) Not denying basic data; 3) Plausibility; 4) The minimum number of brute facts needed; 5) Engagement with and consistency with current science; 6) Lack of ‘promissory notes’; 7) Elegance and simplicity; 8) Clarity versus fudge. Berkeley’s Idealism and Physicalism (in both qualia (...) realist and non-realist variants) are taken as examples and compared according to these criteria. Physicalism fares surprisingly poorly. It is all but inevitable that each person will possess a metaphysical system – and act upon it. If we fail to research alternatives then we are liable to assume a weak position implicitly (typically physicalism), and be reluctant to give it up. (shrink)

Physicalist theories of science, theories of science that is which take physics to be the one basic science and which hold all other sciences to be reducible to physics, have thus far failed to provide a defensible account of cause, state, natural law and explanation. Physicalism has so far been confined to using traditional empiricist concepts of these features of theories. ;This dissertation formally constructs new concepts of scientific explanation by a theory, law of a theory and state description of (...) a theory along lines acceptable to physicalists and indeed modeled on actual physical practice. It differs most noticably from standard empiricist accounts by taking a state description of an individual of a theory to be an exhaustive description of the individual in terms of the predicates of the theory and then demanding that the laws of the theory, taken together, allow us to generate new state descriptions for systems of individuals for regions of space and time in which the system evolves independently of external influences. The status of laws as laws is here no longer regarded in the traditional empiricist way as a function solely of their grammatical form and their truth. Instead lawlikeness is granted to laws in virtue of their membership in a system of laws, the system having the property of generating appropriate sets of new state descriptions. ;Further developments show that more than one system of laws can accomplish the same end result. Three systems of laws are studied in detail. They correspond to the systems of mechanistic laws, of conservation laws, and of force laws in classical physics. Algorithms are given for generating the latter two from the set of mechanistic laws. ;Finally, the physicalist doctrine of the final reducibility of all sciences to physics is embodied in a second type of system of laws which correlates state descriptions of a lower level with ones of a higher level . This second type thus comprises the principles of redescription by which the ontology of a higher level science is reduced to that of a lower. (shrink)

This chapter demonstrates how natural theology is both encouraged and challenged by the findings of the physical sciences. The scientific method is committed to finding naturalistic explanations, yet the vision that it gives suggests there is more to it than meets this particular eye: the universe seems to be permeated with signs of ‘mind’. The mysterious quantum world has shown us that new ways of thinking are required to deal with material ‘reality’. Quantum theory has also revealed new forms of (...) matter with ‘miraculous’ properties. These properties are not evidence of supernatural intervention in the normal running of the universe but manifestations of a deeper rationality that lay undiscovered by classical physics. (shrink)

It is at this juncture that post-modernism in the science field lacks that remaining piece of discipline, accepting the existence of an absolute, inner fabric of creative intelligence that is responsible for the vibratory formation of all physical world phenomena. It is for this reason that science alone will not find a viable answer of how the universe was created. Thus far, the science hierarchy has supplied us with theories that are totally incompatible with the belief that the universe had (...) an origin connected to a creative force. Their contradictions come as a result of their atheistic/agnostic beliefs. It is the time in our evolution to make a changing of the guard. We need a new paradigm, a practical application that people can make sense of and find valuable in their daily lives. (shrink)

Thomas Hofweber argues that the thesis of direct reference is incompatible with physicalism, the claim that the nonphysical supervenes on the physical. According to Hofweber, direct reference implies that some physical objects have object-dependent properties, such as being Jones’s brother, which depend on particular objects for their existence and identity. Hofweber contends that if some physical objects have object-dependent properties, then Local-Local Supervenience (the physicalist doctrine on which he concentrates) fails. In this note, we argue that Hofweber has failed to (...) show that the possession by physical objects of object-dependent properties implies the falsity of Local-Local Supervenience. (shrink)

I have written extensively of the topic of this tutorial. But in order to reach a broad audience I have in many of my more recent works refrained from using equations. That approach makes those works accessible in principle both to readers who are repelled by equations, and also to quantum physicists who are sufficiently familiar with the details of the quantum theory of measurement to be able to fill in for themselves the omitted equations. However, that approach means also (...) that an important class of potential readers is not being optimally reached. This class consists of persons having an engineering or mathematical background, and possessing perhaps even some familiarity with classical physics, but who have little knowledge of quantum mechanics.

In this chapter I argue that there is such a barrier created by self-conscious intentional states—conscious intentional states that are about one’s own conscious intentional states. As we will see, however, this result is entirely compatible with a scientific theory of mind, and, in fact, there is an elegant non-reductive framework in which just such a theory may be pursued.

Edited by a leading exponent of the school, this book offers--in the words of the movement's founders--logical positivism's revolutionary theories on meaning and metaphysics, the nature of logic and mathematics, the foundations of knowledge ...

The standard paradigm for mental causation is a person’s acting for a reason. Something happens - she intentionally φ’s - the occurrence of which we explain by citing a relevant belief or desire. In the present context, I simply take for granted the following two conditions on the appropriateness of this explanation. First, the agent φ’s _because_ she believes/desires what we say she does, where this is expressive of a _causal_ dependence.1 Second, her believing/desiring this gives her a _reason_ for (...) φ-ing: recognizing that she has this belief/desire makes her φ-ing intelligible as rational in the light of her other attitudes and circumstances. A further condition must be met, though, if this is to be a genuine psychological explanation, a case of her acting _for_ the reason in question. Consider the following example of Davidson’s (1973, p. 79). An exhausted climber is desperate to rid herself of the weight and danger of holding her partner on a rope; and her sudden realization that simply letting go would achieve this so unnerves her that her grip loosens slightly and he falls. Her releasing him causally depends upon her having this belief and desire, which provide _a_ reason for doing what she does. But this is not _why_ she does it: it would be at best misleading to say that she dropped him, intentionally, because she was fed up with holding his weight, or because she thought that she might otherwise fall. Her letting go does not depend upon her having these reasons in the right way. The reason-giving relation is causally irrelevant. If we are to explain a person’s acting _for_ a reason, then her doing. (shrink)
