God and the Argument from Consciousness: A Response to Lim

Recently, Daniel Lim has published a thoughtful critique of one form of my argument for the existence of God from consciousness (hereafter, AC).1 After stating his presentation of the relevant contours of my argument, I shall present the main components of his critique, followed by my response. Since one purpose of my publications of AC has been to foster discussion about a neglected argument for God’s existence, I am thankful to lim for his interesting article and the chance to further the discussion

Oppy on the Argument from Consciousness: A Rejoinder

Graham Oppy had criticized my argument for God from consciousness (AC) in my recent book ’Consciousness and the Existence of God’ (N.Y.: Routledge, 2008). In this article I offer a rejoinder to Oppy. Specifically, I respond to his criticisms of my presentation of three forms of AC, and interact with his claims about theism, consciousness and emergent chemical properties

A Bayesian approach to the aperture problem of 3D motion perception

We suggest a geometric-statistical approach that can be ap- plied to the 3D aperture problem of motion perception. In simulations and psychophysical experiments we study per- ceived 3D motion direction in a binocular viewing geometry by systematically varying 3D orientation of a line stimulus moving behind a circular aperture. Although motion direc- tion is inherently ambiguous perceived directions show sys- tematic trends and a Bayesian model with a prior for small depth followed by slow motion in 3D gives reasonable fits to individual data. We conclude that the visual system tries to minimize velocity in 3D but that earlier disparity processing strongly influences perceived 3D motion direction. We discuss implications for the integration of disparity and motion cues in the human visual system

Viscosity from elliptic flow: the path to precision

Using viscous relativistic hydrodynamics we show that systematic studies of the impact parameter dependence of the eccentricity scaled elliptic flow can distinguish between different models for the calculation of the initial source eccentricity. This removes the largest present uncertainty in the extraction of the specific viscosity of the matter created in relativistic heavy-ion collisions from precise elliptic flow measurements.Comment: 4 pages, incl. 4 figure
