    Emergence of Time.George F. R. Ellis & Barbara Drossel - 2020 - Foundations of Physics 50 (3):161-190.
    Microphysical laws are time reversible, but macrophysics, chemistry and biology are not. This paper explores how this asymmetry arises due to the cosmological context, where a non-local Direction of Time is imposed by the expansion of the universe. This situation is best represented by an Evolving Block Universe, where local arrows of time emerge in concordance with the Direction of Time because a global Past Condition results in the Second Law of Thermodynamics pointing to the future. At the quantum level, (...)

    Contextual Emergence of Physical Properties.Robert C. Bishop & George F. R. Ellis - 2020 - Foundations of Physics 50 (5):481-510.
    Contextual emergence was originally proposed as an inter-level relation between different levels of description to describe an epistemic notion of emergence in physics. Here, we discuss the ontic extension of this relation to different domains or levels of physical reality using the properties of temperature and molecular shape as detailed case studies. We emphasize the concepts of stability conditions and multiple realizability as key features of contextual emergence. Some broader implications contextual emergence has for the foundations of physics and cognitive (...)

    How Downwards Causation Occurs in Digital Computers.George Ellis & Barbara Drossel - 2019 - Foundations of Physics 49 (11):1253-1277.
    Digital computers carry out algorithms coded in high level programs. These abstract entities determine what happens at the physical level: they control whether electrons flow through specific transistors at specific times or not, entailing downward causation in both the logical and implementation hierarchies. This paper explores how this is possible in the light of the alleged causal completeness of physics at the bottom level, and highlights the mechanism that enables strong emergence to occur. Although synchronic emergence of higher levels from (...)

    The Causal Closure of Physics in Real World Contexts.George F. R. Ellis - 2020 - Foundations of Physics 50 (10):1057-1097.
    The causal closure of physics is usually discussed in a context free way. Here I discuss it in the context of engineering systems and biology, where strong emergence takes place due to a combination of upwards emergence and downwards causation. Firstly, I show that causal closure is strictly limited in terms of spatial interactions because these are cases that are of necessity strongly interacting with the environment. Effective Spatial Closure holds ceteris parabus, and can be violated by Black Swan Events. (...)

  8. Physics and the Real World.George F. R. Ellis - 2006 - Foundations of Physics 36 (2):227-262.
    Physics and chemistry underlie the nature of all the world around us, including human brains. Consequently some suggest that in causal terms, physics is all there is. However, we live in an environment dominated by objects embodying the outcomes of intentional design (buildings, computers, teaspoons). The present day subject of physics has nothing to say about the intentionality resulting in existence of such objects, even though this intentionality is clearly causally effective. This paper examines the claim that the underlying physics (...)

    Emergence in Solid State Physics and Biology.George F. R. Ellis - 2020 - Foundations of Physics 50 (10):1098-1139.
    There has been much controversy over weak and strong emergence in physics and biology. As pointed out by Phil Anderson in many papers, the existence of broken symmetries is the key to emergence of properties in much of solid state physics. By carefully distinguishing between different types of symmetry breaking and tracing the relation between broken symmetries at micro and macro scales, I demonstrate that the emergence of the properties of semiconductors is a case of strong emergence. This is due (...)

    Spekulative Theorien bedürfen laut einigen Forschern keiner experimentellen Überprüfung, um als wissenschaftlich zu gelten. Dieser Ansatz untergräbt die Wissenschaft.Im vergangenen Jahr nahm eine Debatte in der Physik eine beunruhigende Wende: Nicht alle fundamentalen Theorien lassen sich anhand von Beobachtungen überprüfen und so fordern einige Wissenschaftler, das Vorgehen in der theoretischen Physik anzupassen. Sei eine Theorie nur ausreichend elegant und aussagekräftig, so ihr Appell, müsse diese nicht experimentell überprüft werden – das bricht mit jahrhundertealter philosophischer Tradition, nach der wissenschaftliche Erkenntnis sich (...)

    Plato's Cave Revisited: Science at the Interface.Guenter Mahler & George Ellis - 2008 - Mind and Matter 7 (1):9-36.
    Scientific exploration and thus our knowledge about the outside world is subject to the conditions of our experience.These conditions are condensed here into an interface model which,besides being physical,has an additional interface structure not reducible to physics. We suggest that this structure can dynamically be characterized by separate modes.Their selection and operation presupposes free will and a rudimentary concept of time and space. Based on some analogies with quantum networks it is argued that the 'observed' gets 'dressed'as a consequence of (...)

    Revenge and Forgiveness in the New South Africa.Dan Joseph Stein, Jack van Honk & George Ellis - 2013 - Behavioral and Brain Sciences 36 (1):37-38.
    Insofar as South Africa underwent a rapid transformation from apartheid to democracy, it may provide a unique laboratory for investigating aspects of revenge and forgiveness. Here we suggest that observations and data from South Africa are partially consistent with the hypotheses generated by MCullough and colleagues. At the same time, the rich range of revenge and forgiveness phenomena in real-life settings is likely to require explanatory concepts other than specialized modules and their computational outputs.
