If the mental is subject to indeterminacy, does this rule out the possibility of psychophysical laws? One might think so. However, Jaegwon Kim has argued for the existence of a kind of psychophysical law that is not obviously susceptible to problems posed by indeterminacy. I begin by introducing a weak and relatively uncontroversial indeterminacy thesis. Then, by appealing to constraints on theories of strong supervenience and to general considerations about the nature of indeterminacy, I argue that even (...) Kim’s laws cannot accommodate indeterminacy. The result is an argument against the possibility of Kim‐Style psychophysical laws. (shrink)

A new approach to the 'hard problem'of consciousness, the eons-old mind-body problem, is proposed, inspired by Whitehead, Schopenhauer, Griffin, and others. I define a 'simple subject' as the fundamental unit of matter and of consciousness. Simple subjects are inherently experiential, albeit in a highly rudimentary manner compared to human consciousness. With this re-framing, the 'physical' realm includes the 'mental' realm; they are two aspects of the same thing, the outside and inside of each real thing. This view is known as (...) panpsychism or panexperientialism and is in itself a partial solution to the hard problem. The secondary but more interesting question may be framed as: what is a 'complex subject'? How do simple subjects combine to form complex subjects like bats and human beings? This is more generally known as the 'combination problem'or the 'boundary problem', and is the key problem facing both materialist and panpsychist approaches to consciousness. I suggest a new approach for resolving this component of the hard problem, a 'general theory of complex subjects' that includes 'psychophysical laws' in the form of a simple mathematical framework. I present three steps for characterizing complex subjects, with the physical nature of time key to this new understanding. Viewing time as fundamentally quantized is important. I also suggest, as a second-order conceptualization, that 'information' and 'experience' may be considered identical concepts and that there is no double-aspect to information. Rather, there is a single aspect to information and it is inherently experiential. Tononi's, Chalmers', and Freeman's similar theories are compared and contrasted. (shrink)

Supervenience entails psychophysical principles, but this is compatible with anomalous monism. On what constitutes a strict psychophysical law.

Neil Sinhababu :89–98, 2017) has recently argued against the fine-tuning argument for God. They claim that the question of the universe’s fine-tuning ought not be ‘why is the universe so hospitable to life?’ but rather ‘why is the universe so hospitable to morally valuable minds?’ and that, moreover, the universe isn’t so hospitable. For it is metaphysically possible that psychophysical laws be substantially more permissive than they in fact are, allowing for the realisation of morally valuable consciousness by (...) exceptionally simple physical states and systems, rather than the complex states of brains. I reply that Sinhababu’s argument rests upon unsupported claims and that we have reason to doubt that an omnibenevolent God would make the psychophysical laws more permissive than they in fact are.

Nearly 30 years have passed since Donald Davidson first presented his ar- gument against the possibility of psychophysical laws in “Mental Events”. The argument applies to intentional rather than phenomenal properties, so whenever I refer to mental properties and to psychophysical laws it should be understood that I mean intentional properties and laws relating them to physical properties. No consensus has emerged over what the argument actually is, and the subsequent versions of it presented by (...) Davidson show significant differences. But many have been inclined to agree with the spirit of the argument and with its conclusion. (shrink)

Davidson argues that the connection between belief and the "constitutive ideal of rationality" precludes the possibility of their being any type-type identities between mental and physical events. However, there are radically different ways to understand both the nature and content of this "constitutive ideal," and the plausibility of Davidson’s argument depends on blurring the distinction between two of these ways. Indeed, it will be argued here that no consistent understanding of the constitutive ideal will allow it to play the dialectical (...) role Davidson intends for it. (shrink)

Donald Davidsons classic argument for the impossibility of reducing mental events to physicallistic ones is analyzed and formalized in relational logic. This makes evident the scope of Davidsons argument, and shows that he is essentially offering a negative transcendental argument, i.e., and argument to the impossibility of certain kinds of logical relations. Some final speculations are offered as to why such a move might, nevertheless, have a measure of plausibility.

This volume presents a series of studies that expand laws, invariants, and principles of psychophysics beyond its classical domain of sensation.

In Fechner's psychophysics, the 'mental' and the 'physical' were conceived as two phenomenal domains, connected by functional relations, not as two ontologically different realms. We follow the path from Fechner's foundational ideas and Mach's radical programme of a unitary science to later approaches to primary, psychophysically neutral experience (phenomenology, protophysics). We propose an 'integral psychophysics' as a mathematical study of law-like, invariant structures of primary experience. This approach is illustrated by a reinterpretation of psychophysical experiments in terms of perceptual (...) situations involving a constructed apparatus and an instructed subject. The problematic notion of 'measurement of sensation' is thus eliminated: 'sensations' are merely indices for classes of perceptually equivalent configurations (states of the apparatus) specified by the instruction. The locus of the measured is in the inter-subjectively shared, communicable world—not inside the subject's mind. Finally we discuss the role of integral psychophysics as a scientia prima , logically and methodically preceding physics and psychology. (shrink)

The thesis, typical among dualists, that there are no necessitation relations between events of consciousness and physical events implies that it is prima facie lucky that in our world the apparently existing psychophysical laws usually match events of consciousness and physical events in a “harmonious” way. The lucky psychophysical laws argument concludes that typical dualism amounts to a psychophysical parallelism that is prima facie too improbable to be true. I argue that an anthropic reasoning in (...) the space of possible worlds makes the appearance of a harmonious match situation unsurprising, and that this is all that is needed for the argument to be harmless to a typical dualist.

In past and modern psychophysics there are several unresolved methodological and philosophical problems of human and animal perception, including the outstanding question of the relational basis of whole psychophysics. Here the main issue is discussed: if, and to what extent, there are viable bridges between the traditional “gestalt” oriented approaches and the modern perceptual-cognitive perspectives in psychophysics. Thereby the key concept of psychological “frame of reference” is presented by pointing to Hermann Ebbinghaus' geometric-optical illusions, on the one hand, and Max (...) Wertheimer's treatment of the traditional transposition phenomenon, on the other hand. A much-needed theoretical reorientation of future research may help to overcome the philosophical narrowness of present-day human and comparative psychophysics. (shrink)

Since the founding of psychophysics in the latter half of the nineteenth century, controversy has raged over the subject matter of psychophysical laws. Originally, Fechner characterized psycho physics as the science describing the relation between physical magnitudes and the sensations these magnitudes produce in us. Today many psycho-physicists would deny that sensation is or could be a topic of psycho-physical investigation. I consider Savage's (1970) influential objections to the possibility of such an investigation and argue that they depend (...) upon (i) holding psychophysics to higher standards than those to which we hold other sciences; and (ii) misrepresenting Fechner's stated goals for psychophysics. (shrink)

Fechner's conception of psychophysics included both “outer psychophysics” the relation between stimulus intensity and the response reflecting sensation strength, and “inner psychophysics” the relation between neurelectric responses and sensation strength. In his own time outer psychophysics focussed on the form of the psychophysical law, with Fechner espousing a logarithmic law, Delboeuf a variant of the logarithmic law incorporating a resting level of neural activity, and Plateau a power law. One of the issues on which the dispute was focussed concerned (...) the appearance of contrasts if the overall illumination was increased or decreased; another issue was the question of whether a sensation of a “just noticeable difference” established for one value of a sensory dimension appeared the same for a value elsewhere on the dimension. The development of “inner psychophysics” led through the works of Delboeuf, Solomons, Jastrow, and Thurstone to modern signal detection theory. A third line of research, devoted to the question of what was meant by the “measurement” of sensation strength, stemmed from the criticism of Fechner's work by von Kries (1882) and others. Although a valid body of science could be built up without the intervening variable called “sensation strength,” such a science might be a cumbersome representation of reality. When an optical contrast is set up, and its overall illumination is increased or decreased, subjective contrasts involving medium levels of lightness vary little as illumination varies (as a power law based on sensation ratios or a logarithmic law based on sensation differences predict), but subjective contrasts involving extreme levels of lightness might be subject to the effects of other variables.

Hermann von Helmholtz has been widely acknowledged as one of the forerunners of contemporary theories of measurement. However, his conception of measurement differs from later, representational conceptions in two main respects. Firstly, Helmholtz advocated an empiricist philosophy of arithmetic as grounded in some psychological facts concerning quantification. Secondly, his theory implies that mathematical structures are common to both subjective experiences and objective ones. My suggestion is that both of these differences depend on a classical approach to measurement, according to which (...) the arithmetic laws of addition define what is measurable as a particular domain for their application, and, at the same time, the extensibility of these laws to all known physical processes works as a heuristic principle for empirical research. Such an approach is worth reconsidering, not only because it lends plausibility to some of the controversial aspects of Helmholtz’s theory, but also because it offers a philosophical perspective on quantification problems that originated in the nineteenth-century.This paper draws insights on Helmholtz’s philosophical views from his engagement with the measurability of sensations via Fechner’s psychophysical law. This seems to be in contrast with the fact that the reception of Helmholtz’s theory culminated with the formulation of the theory of extensive measurement. I will contend that Helmholtz reached a no less important standpoint in the nineteenth-century debate on whether sensations are different (i.e., intensive) kinds of magnitudes and on how, if at all, they can be measured.

Argues that there can be interaction without breaking physical laws: e.g. by basic psychic forces, or by varying physical constants, or especially by arranging fractal trees of physical causation leading to behavior.

The traditional view of science holds that science is essentially nomothetic—that is, the defining characteristic of science is that it seeks to discover and formulate laws for the phenomena in its domain, and that laws are required for explanation and prediction. This paper advances the thesis that there are no laws in the special sciences, sciences other than fundamental physics, and that this does not impugn their status as sciences. Toward this end, two arguments are presented. The (...) first begins with Donald Davidson’s argument against psychophysical laws and develops a more perspicacious general argument against special science laws. The second is a generalized and more explicitly motivated argument based on J. J. C. Smart’s claim that biology, unlike physics, has no laws. (shrink)

A key working hypothesis in neuroscience is ‘materialistic reductionism’, i.e., the assumption whereby all physiological, behavioral or cognitive phenomena is produced by localized neurochemical brain activation (but not vice versa). However, analysis of sub-threshold Weber’s psychophysical stimulation indicates its computational irreducibility to the direct interaction between psychophysical stimulation and any neuron/s. This is because the materialistic-reductionistic working hypothesis assumes that the determination of the existence or non-existence of any psychophysical stimulation [s] may only be determined through its (...) direct interaction [di1] with a given neuron/s [N] that together forms the ‘neural registry’ computational level [NR/di1]. But, this implies that in cases of (initial) sub-threshold (sensory-specific) psychophysical stimulation which is increased above the sensory-specific threshold but below Weber’s psychophysical ‘dv’—the psychophysical computational processing [PCP] produces an apparently ‘computationally indeterminate’ output. This is because materialistic reductionism asserts the contingency of PCP upon the existence of a direct interaction between ‘s’ and ‘N’ within the NR/di1 level, but in the special case of Weber’s sub-threshold psychophysical stimulation the same PCP/di1 also asserts the non-existence of ‘s’ (as demanded by Weber’s psychophysical law). However, given robust empirical evidence indicating the capability of PCP to determine whether (or not) ‘s’ exists, we must conclude that PCP may not be carried out from within NR’s direct interaction between a particular psychophysical stimulation and any set of neuron/s in the brain. Hence, the Duality Principle asserts the conceptual irreducibility of sub-threshold psychophysical stimulation to any direct NR/di1: s-N interaction, thereby challenging the current materialistic-reductionistic assumption.

The defining characteristics anticipated for any prospective psychophysically neutral language are explored in this essay through the analysis and comparison of two previous approaches. The idea of a psychophysically neutral language was first articulated byWolfgang Pauli in the context of the dual-aspect theory of mind and matter that he developed with C.G. Jung. The first approach discussed is George Spencer Brown's Laws of Form. An overview is given, followed by a review of the critical responses and extensions of the (...) work, particularly Francisco Varela's attempt to use it to formalize biological autopoiesis and Louis Kaufman's development of Brownian algebra. The mathematical basis of Spencer Brown's calculus and its philosophical assumptions and implications are then investigated. The second approach discussed is Marie-Louise von Franz's Number and Time, an investigation of number archetypes through which she continued the inquiry begun by Jung and Pauli. The central tenets of her work are summarized and critically evaluated, and a comparison with Spencer Brown's work is carried out. Finally, implications are drawn for any future attempt to formulate a psychophysically neutral language. (shrink)
