Epistemic divergence occurs when different investigators give different answers to the same question using evidence-collecting methods that are not public. Without following the principle that scientific methods must be public, scientific communities risk epistemic divergence. I explicate the notion of public method and argue that, to avoid the risk of epistemic divergence, scientific communities should (and do) apply only methods that are public.

The emperor's new mind (hereafter Emperor) is an attempt to put forward a scientific alternative to the viewpoint of according to which mental activity is merely the acting out of some algorithmic procedure. John Searle and other thinkers have likewise argued that mere calculation does not, of itself, evoke conscious mental attributes, such as understanding or intentionality, but they are still prepared to accept the action the brain, like that of any other physical object, could in principle be simulated by (...) a computer. In Emperor I go further than this and suggest that the outward manifestations ofconscious mental activity cannot even be properly simulated by calculation. To support this view, I use various arguments to show that the results of mathematical insight, in particular, do not seem to be obtained algorithmically. The main thrust ofthis work, however, is to present an overview ofthe present state of physical understanding and to show that an important gap exists at the point where, quantum and classical physics meet, as well as to speculate on how the conscious brain might be taking advantage ofwhatever new physics is needed to fill this gap to achieve its nonalgorithmic effects.

The relation between first and higher order mental states is currently unknown. In particular, the relation between conscious experience and introspection is difficult as the same methods are used to investigate them. In order to make progress in the scientific understanding of consciousness, introspection or both, it is fundamental to understand whether their relation is serial or reciprocal. Although the amount of empirical evidence directly addressing this question is sparse, the little that exists suggests a more complex situation that must (...) be taken into account in order to characterise the relationship between first and higher order mental states. We propose a testable integrative model in an attempt to explain the existing data and to make new empirical predictions. (shrink)

The way people come to report private stimulation arising within their own bodies is not well understood. Although the Darwinian assumption of biological continuity has been the basis of extensive animal modeling for many human biological and behavioral phenomena, few have attempted to model human communication based on private stimulation. This target article discusses such an animal model using concepts and methods derived from the study of discriminative stimulus effects of drugs and recent research on interanimal communication. We discuss how (...) humans acquire the capacity to identify and report private stimulation and we analyze intra- and interspecies differences in neurochemical mechanisms for transducing interoceptive stimuli, enzymatic and other metabolic factors, learning ability, and discrimination learning histories and their relation to psychiatric and developmental disabilities.

The purposes of this paper are twofold: first, I wish to correct a systematic bias in Husserlian transcendental phenomenology. This bias is in favor of intuition of essences of meaning and against the intuition of essences of sensation. This bias is explained as a product of Husserl's mind-body dualism. Second, I suggest the possibility of a neurophenomenology from a biogenetic structural point of view. This neurophenomenology merges the knowledge of essences derived from mature contemplation with knowledge of the structures of (...) experience derived from neuroanthropology. After addressing these two issues I proceed to describe the sensorium from a neurophenomenological perspective, and the constituent element of perception, the dot. I hypothesize fat experience arises in the dialogue between prefrontal cortical processes and sensorial processes, that experience is constituted within a field of sensorial dots that arise and dissolve in temporal frames. I conclude that Husserl's view of the phenomenology of time is essentially correct and is both in keeping with findings from current neurophysiology, and amenable to a modem scientific view of consciousness and to many of the religious traditions encountered by ethnographers. The implications of a neurophenomenology for the anthropological study of consciousness are suggested. (shrink)
