Restrictions on research on therapeutic cloning are questionable as they inhibit the development of a technique which holds promise for succesful application of pluripotent stem cells in clinical treatment of severe diseases. It is argued in this article that the ethical concerns are less problematic using therapeutic cloning compared with using fertilised eggs as the source for stem cells. The moral status of an enucleated egg cell transplanted with a somatic cell nucleus is found to be more clearly not equivalent (...) to that of a human being. Based on ethical considerations alone, research into therapeutic cloning should be encouraged in order to develop therapeutic applications of stem cells. (shrink)

An explanatory gap exists between physics and experience, raising the hard problem of consciousness: why are certain physical systems associated with an experience of an external world from an internal perspective? The living mirror theory holds that consciousness can be understood as arising from the computational interaction between a living system and its environment that is required for the organism's existence and survival. Maintaining a boundary that protects the system against destructive forces requires an interaction between the organism and its (...) outside world that can be cast in terms of Bayesian inference. The living mirror theory holds that this computational interaction results in statistical properties of the material world that are, in the absence of life, only implicit, becoming explicit in informational terms. This is held to give rise to the beliefs in qualities that constitute consciousness. Consciousness is therefore a necessary feature of all living systems as, in a world governed by the second law of thermodynamics, survival depends on the construction of beliefs regarding the potentially destructive forces in the outside world. From this perspective, consciousness is shown to be not a property of the brain in particular but instead to be a necessary feature of the life process itself. (shrink)

We study the relationship between various properties of the real numbers and weak choice principles.
