Knowledge is a central concept within both Bayesian inference and the mathematical and philosophical program of logic and semiotics initiated by Charles Sanders Peirce and further developed by George Spencer-Brown and Louis Kauffman. The latter school is more philosophical than is usual with the practitioners of Bayesian inference and claims the existence of a world mind. When these two...

A strategy to replace the ethylamine side chain of 2,5-dimethoxy-4-iodoamphetamine (DOI, 1a), and 2,5-dimethoxy-4-bromoamphetamine (DOB, 1b) with a cyclopropylamine moiety was successful in leading to compounds with high affinity at the 5-HT(2) family of receptors; and the more potent stereoisomer of the cyclopropane analogues had the expected (-)-(1R,2S)-configuration. Screening for affinity...

Psilocybin is a classic psychedelic and a candidate drug model of psychosis. This study measured the effects of psilocybin on resting-state network and thalamocortical functional connectivity (FC) using functional magnetic resonance imaging (fMRI). Fifteen healthy volunteers received intravenous infusions of psilocybin and placebo in 2 task-free resting-state scans. Primary analyses focused on...
Metaphilosophy October 1, 2012 J. M. Fritzman, Kristin Parvizian
Abstract: The nonmetaphysical interpretation ofHegel's philosophy asserts that the metaphysical reading is not credible and so his philosophy must be rationally reconstructed so as to elide its metaphysical aspects. This article shows that the thesis of the extended mind approaches the metaphysical reading, thereby undermining denials of its credibility and providing the resources to articulate...
Topics in Cognitive Science October 1, 2012 Julian Kiverstein 72 citations
There is substantial disagreement among philosophers of embodied cognitive science about the meaning of embodiment. In what follows, I describe three different views that can be found in the current literature. I show how this debate centers around the question of whether the science of embodied cognition can retain the computer theory of mind. One view, which I will label body functionalism,...

Abstract Recent years have seen a growing interest in Buddhist thought as a potential source of alternative conceptions of the nature of the mind and the relation between the mental and the physical. This article considers and assesses three different models of what contemporary philosophy of mind can learn from Buddhist thought. One model, advocated by Alan Wallace, holds that we can learn...

Cognitive scientists typically classify cognitive processes as either controlled or automatic. Whereas controlled processes are slow and effortful, automatic processes are fast and involuntary. Over the past decade, we have propelled a research trajectory investigating how top-down influence in the form of suggestion can allow individuals to modulate the automaticity of cognitive processes....
Entropy September 7, 2012 A. Ehresmann
MENS is a bio-inspired model for higher level cognitive systems; it is an application of the Memory Evolutive Systems developed with Vanbremeersch to model complex multi-scale, multi-agent self-organized systems, such as biological or social systems. Its development resorts to an info-computationalism: first we characterize the properties of the human brain/mind at the origin of higher order...

Realism about cognitive or semantic phenomenology, the view that certain conscious states are intrinsically such as to ground thought or understanding, is increasingly being taken seriously in analytic philosophy. The principle aim of this paper is to argue that it is extremely difficult to be a physicalist about cognitive phenomenology. The general trend in later 20th century/early 21st...
