    Precis of the Emperor's New Mind.Roger Penrose - 1990 - Behavioral and Brain Sciences 13 (4):643-705.
    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 (...)

  9. Conscious Events as Orchestrated Space-Time Selections.Stuart R. Hameroff & Roger Penrose - 1996 - Journal of Consciousness Studies 3 (1):36-53.
    What is consciousness? Some philosophers have contended that ‘qualia’, or an experiential medium from which consciousness is derived, exists as a fundamental component of reality. Whitehead, for example, described the universe as being comprised of ‘occasions of experience’. To examine this possibility scientifically, the very nature of physical reality must be re-examined. We must come to terms with the physics of space-time -- as is described by Einstein's general theory of relativity -- and its relation to the fundamental theory of (...)

    The Big Bang and its Dark-Matter Content: Whence, Whither, and Wherefore.Roger Penrose - 2018 - Foundations of Physics 48 (10):1177-1190.
    The singularity theorems of the 1960s showed that Lemaître’s initial symmetry assumptions were not essential for deriving a big-bang origin for a vast multitude of relativistic universe models. Yet the actual universe accords remarkably closely with models of Lemaître’s type. This is a mystery closely related to the form taken by the 2nd law of thermodynamics and is not explained by currently conventional inflationary cosmology. Conformal cyclic cosmology provides another perspective on these issues, one consequence being the necessary initial presence (...)

    What 'Gaps'? Reply to Grush and Churchland.Roger Penrose & Stuart R. Hameroff - 1995 - Journal of Consciousness Studies 2 (2):98-111.
    Grush and Churchland (1995) attempt to address aspects of the proposal that we have been making concerning a possible physical mechanism underlying the phenomenon of consciousness. Unfortunately, they employ arguments that are highly misleading and, in some important respects, factually incorrect. Their article ‘Gaps in Penrose’s Toilings’ is addressed specifically at the writings of one of us (Penrose), but since the particular model they attack is one put forward by both of us (Hameroff and Penrose, 1995; 1996), it is appropriate (...)

    Quantum Concepts in Space and Time.Roger Penrose & C. J. Isham (eds.) - 1986 - New York ;Oxford University Press.
    Recent developments in quantum theory have focused attention on fundamental questions, in particular on whether it might be necessary to modify quantum mechanics to reconcile quantum gravity and general relativity. This book is based on a conference held in Oxford in the spring of 1984 to discuss quantum gravity. It brings together contributors who examine different aspects of the problem, including the experimental support for quantum mechanics, its strange and apparently paradoxical features, its underlying philosophy, and possible modifications to the (...)

    On the Gravitization of Quantum Mechanics 1: Quantum State Reduction.Roger Penrose - 2014 - Foundations of Physics 44 (5):557-575.
    This paper argues that the case for “gravitizing” quantum theory is at least as strong as that for quantizing gravity. Accordingly, the principles of general relativity must influence, and actually change, the very formalism of quantum mechanics. Most particularly, an “Einsteinian”, rather than a “Newtonian” treatment of the gravitational field should be adopted, in a quantum system, in order that the principle of equivalence be fully respected. This leads to an expectation that quantum superpositions of states involving a significant mass (...)

    Features of consciousness difficult to understand in terms of conventional neuroscience have evoked application of quantum theory, which describes the fundamental behavior of matter and energy. In this paper we propose that aspects of quantum theory (e.g. quantum coherence) and of a newly proposed physical phenomenon of quantum wave function "self-collapse"(objective reduction: OR -Penrose, 1994) are essential for consciousness, and occur in cytoskeletal microtubules and other structures within each of the brain's neurons. The particular characteristics of microtubules suitable for quantum (...)

    It is argued, by use of specific examples, that mathematical understanding is something which cannot be modelled in terms of entirely computational procedures. Our conception of a natural number (a non-negative integer: 0, 1, 2, 3,…) is something which goes beyond any formulation in terms of computational rules. Our ability to perceive the properties of natural numbers depends upon our awareness, and represents just one of the many ways in which awareness provides an essential ingredient to our ability to understand.

    “The Right Thing to Do?” Transformation in South African Sport.Brian Penrose - 2017 - South African Journal of Philosophy 36 (3):377-392.
    In this paper I attempt to unpack the current public debate on racial transformation in South African sport, particularly with regard to the demographic make-up of its national cricket and rugby sides. I ask whether the alleged moral imperative to undertake such transformation is, in fact, a moral imperative at all. I discuss five possible such imperatives: the need to compensate non-white South Africans for the injustices in sport’s racist history, the imperative to return the make-up of our national sides (...)

    Spinors and Torsion in General Relativity.Roger Penrose - 1983 - Foundations of Physics 13 (3):325-339.
    Conformal rescalings of spinors are considered, in which the factor Ω, inε AB ↦Ωε AB, is allowed to be complex. It is argued that such rescalings naturally lead to the presence of torsion in the space-time derivative▽ a. It is further shown that, in standard general relativity, a circularly polarized gravitational wave produces a (nonlocal) rotation effect along rays intersecting it similar to, and apparently consistent with, the local torsion of the Einstein-Cartan-Sciama-Kibble theory. The results of these deliberations are suggestive (...)

    Fairness and Political Obligation.Brian Penrose - 2004 - South African Journal of Philosophy 23 (3):282-291.
    In this paper I offer a limited defence of “fairness” or “fair play” arguments for political obligation by focussing on one important critique of such arguments, that offered by A. John Simmons. I isolate Simmons's concentration on the idea of “accepting” benefits and argue that, among other difficulties, his criteria for when we can be said to accept a benefit from our political communities are too restrictive. While the scope of the discussion is narrow, I try to sketch ways in (...)

    The following is an edited version of Roger Penrose's lecture at the Fifth Mind and Brain Symposium at the Institute of Psychiatry, London, on 29 October 1994, introducing the themes of his recent book Shadows of the Mind. The talk begins by outlining some options for the modelling of the relationship between consciousness and computation, and provides evidence for a model in which it is not possible even in principle to simulate mathematical understanding computationally. It is argued that mathematical understanding (...)

    Must the Family Be Just?Brian Penrose - 2000 - Philosophical Papers 29 (3):189-221.
    Abstract Susan Moller Okin has criticized Michael Sandel's view that the family is an example of an institution that is sometimes ?above? or ?beyond? justice, and for which justice is not, under the best conditions, a virtue. She argues that he both misses the point of justice as a virtue of social institutions and that he idealizes the family, and after undertaking this ?ground-clearing?, goes on to argue that families should be just. This paper offers a qualified defense of Sandel. (...)

    Gödel appears to have believed strongly that the human mind cannot be explained in terms of any kind of computational physics, but he remained cautious in formulating this belief as a rigorous consequence of his incompleteness theorems. In this chapter, I discuss a modification of standard Gödel-type logical arguments, these appearing to strengthen Gödel’s conclusions, and attempt to provide a persuasive case in support of his standpoint that the actions of the mind must transcend computation. It appears that Gödel did (...)
