The stream of human consciousness appears to be interruptible, in that we can experience a sensation of ‘returning to ourselves after an absence of content’ (e.g. sleep, anaesthesia, full-absorption meditation). Prima facie, such evidence poses a challenge to simple applications of theories of consciousness based on electromagnetic or neural activity in the brain, because some of this activity persists during periods of interruption. This paper elaborates one of several possible responses to the challenge. We build on a previous theory in (...) which EM field topology delineates complex macrophenomenal experience. We first apply an analytic lens to identify different ways in which field topologies might generate sensations of ‘absence of content’. We then test the feasibility of a particular phenomenological approach for assessing those field topologies, powered by the unusual lucidity about cessation pathways induced via certain meditation practices and psychedelic dosages. We build computational simulations of these cessation pathways and test them on eight interviewees with various levels of experience in cessation states. We conclude that this approach can generate usable insight, but requires further formalisation to fulfil its potential. The findings tentatively support our claims but the theory remains speculative at this stage. We set out empirical tests with 11 specific predictions, both for further phenomenological research and for brain manipulation research. Although they align neatly, our ontological and cessation theories can also be separated. The paper describes how our theories can be consistent with other perspectives on consciousness, such as variants of predictive processing or global network theory. (shrink)

Although at first glance, “facts” are the paradigms of straightforwardness, something about facts seems to invite perpetual controversy and dichotomizing. Innumerable bifurcations on the topic have included "Facts vs. Theories”, “Facts vs. Appearance”, "Facts vs. Values", ... and, popular nowadays, "(Real)Facts vs. Fake Facts". This paper most aligns with the facts vs. theories model, so far as whatever facts are, theories seem to be constructed stories that are necessary for connecting and interpreting the facts. Yet the boundary between the two (...) is fluid and fuzzy: Fact in one context is theory in another, depending on what is being accepted or contested at the time. This paper’s views are compatible with—but neutral on the plausibility of having—an optimism like Peirce’s that scientific inquiry may nonetheless converge towards a consensus. To illustrate the challenges of finding “straightforward” facts, the paper includes a case example, related to research on possible health effects of exposure to electromagnetic-field radiation (EMF). _ The source paper for this 2018 update was originally presented at the University of Waterloo 30th Anniversary Philosophy Conference, 1993.

Individuals with idiopathic environmental illness with attribution to electromagnetic fields (IEI-EMF) claim they experience adverse symptoms when exposed to electromagnetic fields (EMFs) from mobile telecommunication devices. However, research has consistently reported no relationship between exposure to EMFs and symptoms in IEI-EMF individuals. The current study investigated whether presence of symptoms in IEI-EMF individuals were associated with a nocebo effect. Data from two previous double-blind provocation studies were re-analyzed based on participants’ judgments as to whether or not they believed a telecommunication (...) base station was “on” or “off.” Experiment 1 examined data in which participants were exposed to EMFs from Global System for Mobile Communication, Universal Mobile Telecommunications System, and sham base station signals. In Experiment 2, participants were exposed to EMFs from Terrestrial Trunked Radio Telecommunications System and sham base station signals. Our measures of subjective well-being indicated IEI-EMF participants consistently reported significantly lower levels of well-being, when they believed the base station was “on” compared to “off.” Interestingly, control participants also reported experiencing more symptoms and greater symptom severity when they too believed the base station was “on” compared to “off.” Thus, a nocebo effect provides a reasonable explanation for the presence of symptoms in IEI-EMF and control participants.

In a number of publications positive associations between the exposure to artificially generated nonionizing electromagnetic fields (EMF) and the reproductive risks in women were reported (abortion, birth defects, stillbirths). Yet, in another studies, claimed to be more careful, it has been shown that EMF should not be accounted for as a factor causing measurable increase in the above mentioned reproductive failures. In this context, of crucial importance is the determination whether the observed relationship between EMF and people is not of (...) casual but of causal character. In epidemiology a simple checklist is often used to establish this type of relationship. However, in the case of weak association the causal relationship may be claimed with a high degree of uncertainty. Taking into account the fact that in situations that are of interest to epidemiology, EMF are one (sometimes seemingly the most important) of a number of factors. Therefore, the above mentioned bioeffects may come into effect only if other factors are also present. It should be also stressed that the intricacy of these relationships increases when the role of such circumstances, as: distribution in time of the expositions, accumulation of dose, different spans of latency periods, as well as possible stimulatory effects of weak EMF is taken into account.

Possible-worlds semantics proved itself as a strong tool in analysing the statements of actuality, possibility, contingency and necessity. But impossible phenomena go beyond the expressive power of the apparatus. The proponents of possible-worlds apparatus thus owe us at least three stories. The first one is the story about ontological nature of possible worlds, the second one is the story about the theoretical role such entities play and the third one is the story about the impossible. Modal Realism (MR) provides us (...) with a positive story regarding the first and the second, but denies impossible worlds. Extended Modal Realism (EMR) adds a positive story about the third point too. This book is an attempt to paraphrase extended modal realism in different metaphysical frameworks. In Chapter I, I outline the theory of modal realism, its systematic account of modality and its ontological commitments. I also motivate an impossible-worlds discourse as well as a systematic appeal of extending the picture beyond the possible. I then propose several definitions of the concept of ‘impossible world’ (or impossible possible world). Finally, I discuss a particular metaphysics behind the concept - extended modal realism. Chapter II considers the epistemological worry associated with (MR) and (EMR) and concludes that although the worry is justified, there can be epistemological justification of the theory. Next, I outline the so-called indispensability argument for the legitimacy of mathematical Platonism. Finally, I argue that the argument, if accepted, can be applied to metaphysics in general, to the existence of concrete possibilia (and impossibilia) in particular. Chapter III focuses on the analysis of (EMR). To be more precise, I present a so-called advanced modalizing problem which seems to be infecting every genuinely realistic theory of modality. In this chapter, I propose a way of treating extraordinary modal claims by means of plurality of logical spaces. The next three chapters provide different ways of understanding (EMR). Namely, Chapter IV develops and defends Extended Modal Dimensionalism (EMD). (EMD) is realism about spaces, times and worlds—metaphysical indices that make objects spatial, temporal and modal, respectively. Metaphysical indices play the role of alethic relativisers, i.e. items to which matters of truth are relativized. The chapter examines several arguments against modal dimensionalism and shows that it offers a feasible way to understand (EMR). Chapter V offers a structural approach to possible and impossible worlds: Extended Modal Structuralism (EMS). In particular, I consider whether it makes sense to think of logical models in isolation from the concrete world but without their being divorced from all spatiotemporal totalities. The metaphysics of structure developed in this chapter assumes that structural properties of possible and impossible worlds are primitive and objective. However, I provide some characterisations of their logical and metaphysical behaviour, as well as guidelines for talking about them. Finally, Chapter VI proposes yet another metaphysical framework of hybrid modal realism. I present theories of (MR), (EMR) and modal fictionalism respectively, their advantages and drawbacks. Finally, I propose a so-called hybrid view. Roughly, the view is that one might be a modal realist when it comes to possibilia, but turn into fictionalism regarding impossibilia. The approach is dubbed Extended Modal Fictionalism (EMF) a version of fictionalism according to which claims made within a certain discourse are better to be understood as a sort of ‘fiction’, rather than as a literal truth.

It is argued that in terms of Thomas Kuhn's analysis of how different fields of science develop and progress, consciousness research is still in the pre-paradigm or pre-science phase that precedes the advent of any universally accepted paradigm. A means by which this long-standing situation may be escaped is here suggested. This is to treat each of the three distinct theoretical positions that presently drive experimental research on the nature of consciousness as mini-paradigms and then apply the same logic that (...) Kuhn sees as underpinning paradigm shifts in mature sciences to decide which of these three mini-paradigms becomes the first universally accepted paradigm of a mature science of consciousness. At present, the three mini-paradigms that drive experimental research on the nature of consciousness are: the cognitive-science process theory mini-paradigm, the neurophysiologists' preferred psychoneural identity theory mini-paradigm and the EMF field theory mini-paradigm. In established science, paradigms shift when enough 'anomalies' – falsified predictions or largely unrecognised but once-recognised-unacceptable consequences – build up to make the existing paradigm uncomfortable for those who operate within it. At this point, a sudden paradigm shift occurs, ushering in another long period of 'normal science' during which the new paradigm drives experimentation. With regard to the three existing mini-paradigms on the nature of consciousness, it is argued that recognition that _processes_ are abstract entities –and that this renders the "consciousness is a process, not a thing" mini-paradigm dualist – makes this mini-paradigm unacceptable to practitioners who regard dualism as unscientific and who prefer to see themselves as staunchly scientific, and therefore as monists.. The strong prediction of the "consciousness is brain activity" mini-paradigm – that conscious experiences should invariably correlate with the firing of either particular single neurons or groups of single neurons in the brain – has now been falsified often enough to make this mini-paradigm unacceptable to its practitioners. And this leaves intact only the "consciousness is a 3-D electromagnetic field" mini-paradigm – the idea that conscious experiences_ are_ particular 3-dimensional patterns in the electromagnetic field generated by brain activity. And as a result, it is suggested that this third mini-paradigm might usefully become the first universally accepted full paradigm, which would finally allow announcement of the birth of a Kuhnian science of consciousness.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 497 interaction and interdependence. Our practice can be governed by that ontological hypothesis. Much of Timpanaro's ranting and raving and name calling rests upon his unhelpful conflation of the epistemological and the ontological and upon a false dichotomy between materialism and idealism that no longer is or ought to be the basic and important issue in Marxism. DONALDC. LEE University of New Mexico Causing, Perceiving and Believing: (...) An Examination of the Philosophy of C. J. Ducasse. By Peter H. Hare and Edward H. Madden. (Dordrecht and Boston: Reidel, 1975. Pp. vii + 211. $26.00) Hare and Madden have performed a service to the philosophical community in summarizing and evaluating the contributions to philosophy of C. J. Ducasse. They have distilled from ten books, scores of articles, and some unpublished manuscripts of Ducasse, analyses of causality, sensation, perception, substance, agency, belief, knowledge, mind, beauty, education, and religion that can fairly be regarded as the philosophy of Ducasse. They point out some inconsistencies in Ducasse's views, but they suggest emendations to overcome the difficulties-emendations that Hare and Madden have developed in their own writings, so that the reader is offered, in effect, a composite Ducasse-Hare-Madden system of philosophy. I agree with most of the authors' judgments regarding the defects of Ducasse's views, but I doubt that their proposed improvements succeed in making the overall vision coherent. In the first three chapters the authors explain Ducasse's theories of causality and agency and claim that his account of causality as a necessary but nonlogical connection was a significant advance over Hume. They consider Ducasse to have been wrong in limiting causality to events and in maintaining that it is directly observable. They argue that an effect is deducible from the "nature" of its cause, although not from the nontheoretical description of its cause. This proposed improvement on Ducasse and Hume seems to me either a mere gloss on Hume or a muddle. If Hare and Madden mean that scientific theories establish entailments between concepts such as pressure and volume or mass and acceleration, and that the explanatory and predictive success of such entailments serves as a criterion of causal processes, they are right. But what they have identified is not a relation of nonlogical necessity but rather two relations: a logical relation between two theoretical concepts, and a contingent relation between two classes of events that correspond to the theoretical concepts. If, on the other hand, they mean to agree with Aristotle and the scholastics that the nature of a thing is an entity or process inside it that compels it to behave as it does, then, like their ancient predecessors, they make causal explanation into a "dormative virtue" fallacy; for the nature of a thing is then identical with its causal powers, and the latter follow vacuously from the concept of its nature. They seem to ignore the fact that any conceptual relation between theoretical concepts is only a rough approximation to actual events. It is a logically necessary truth that EMF is proportional to current times resistance, but it is neither logically nor nonlogically necessary that a booster battery will start a recalcitrant car. In brief, theoretical relations are idealizations of real processes in nature. Hare and Madden claim that their conceptual connection analysis of causality blunts the edge of the "logical connection argument" that motives cannot be causes of actions. They fail to realize that the "logical connection argument" applies to the nontheoretical descriptions of motives and actions (there are no theories worth considering), while their own conceptual relation analysis applies only to theoretical descriptions of natural processes. The Hare-Madden emendation produces special difficulties when applied to Ducasse's account of human agency and mind-body interaction. Ducasse defended the dualist conception of voluntary action as bodily movement caused by mental volitions. The possibility of 498 HISTORY OF PHILOSOPHY such causal intereaction makes some sense on Ducasse's basically Humean view that causality can hold between any two kinds of event but not on the Hare-Madden view that cause and effect must be conceptually related. For we have no well-confirmed theories, nor is it likely that we ever will... (shrink)
