The presumption of movement

The conceptualisation of movement has always been problematical for Western thought, ever since Parmenides declared our incapacity to conceptualise the plurality of change because our self-identical thought can only know an identical being. Exploiting this peculiar feature and constraint on our thought, Zeno of Elea devised his famous paradoxes of movement in which he shows that the passage from a position to movement cannot be conceptualised. In this paper, I argue that this same constraint is at the root of our incapacity to conceptualise the unseen movement at the micro-level and that the aporetic idea of super-position far from opening the gate on a deeper reality is a symptomatic word for this lack of understanding.

Against digital ontology

The paper argues that digital ontology (the ultimate nature of reality is digital, and the universe is a computational system equivalent to a Turing Machine) should be carefully distinguished from informational ontology (the ultimate nature of reality is structural), in order to abandon the former and retain only the latter as a promising line of research. Digital vs. analogue is a Boolean dichotomy typical of our computational paradigm, but digital and analogue are only “modes of presentation” of Being (to paraphrase Kant), that is, ways in which reality is experienced or conceptualised by an epistemic agent at a given level of abstraction. A preferable alternative is provided by an informational approach to structural realism, according to which knowledge of the world is knowledge of its structures. The most reasonable ontological commitment turns out to be in favour of an interpretation of reality as the totality of structures dynamically interacting with each other. The paper is the first part (the pars destruens) of a two-part piece of research. The pars construens, entitled “A Defence of Informational Structural Realism”, is developed in a separate article, also published in this journal.     

Tracing the Development of Thought Experiments in the Philosophy of Natural Sciences

Summary  An overview is provided of how the concept of the thought experiment has developed and changed for the natural sciences in the course of the 20th century. First, we discuss the existing definitions of the term ‘thought experiment’ and the origin of the thought experimentation method, identifying it in Greek Presocratics epoch. Second, only in the end of the 19th century showed up the first systematic enquiry on thought experiments by Ernst Mach’s work. After the Mach’s work, a negative attitude towards thought experiments came in the beginning of the 20th century, which went on until the Thomas Kuhn’s and Karl Popper’s work on thought experiments. Only from the mid-1980s did thought experiments begin to be considered relevant to scientific enterprise. Finally, we show the existing empirical and ‘functional’ theories which have developed about the nature and purpose of thought experiments.     

Psychic energy and synchronicity

Given Jung's interest in physics’ formulations of psychic energy and the concept of time, overlaps and convergences in the themes addressed in analytical psychology and in quantum physics are to be expected. These are informed by the active intersections between the matter of mind and mindfulness re matter. In 1911, Jung initiated dinners with Einstein. Jung's definition of libido in the pivotal 1912 Fordham Lectures reveals the influence of these conversations. Twenty years later, a significant period in physics, Wolfgang Pauli contacted Jung. Their collaboration led to the theory of synchronicity.     

Joseph Rotblat and the Moral Responsibilities of the Scientist

Professor Sir Joseph Rotblat was one of the most distinguished scientists and peace campaigners of the post second world war period. He made significant contributions to nuclear physics and worked on the development of the atomic bomb. He then became one of the world’s leading researchers into the biological effects of radiation. His life from the early 1950s until his death in August 2005 was devoted to the abolition of nuclear weapons and peace. For this he was awarded the Nobel Peace Prize, together with Pugwash Conferences on Science and World Affairs (that he helped found) in 1995. His work in this area ranked with that of Albert Einstein and Bertrand Russell and this article is an attempt to summarise his life, achievements, but in particular outline his views on the moral responsibilities of the scientist. He is a towering intellectual figure and his contributions to mankind should be better known and more widely understood.

Divine Activity and Motive Power in Descartes's Physics

This paper is the second of a two-part reexamination of causation in Descartes's physics. Some prominent contemporary scholars, including Gary Hatfield and Daniel Garber, have argued that Descartes is an Occasionalist about natural motion. On their reading, Descartes holds that God alone causes the motions that are not caused by the free actions of finite minds. Hatfield and Garber offer similar, but independent arguments that Descartes's views about physics – in particular, his arguments that the laws of nature are grounded in God's immutability – entail Occasionalism about natural motion. In this paper I argue contra Hatfield and Garber that Descartes's natural philosophy does not entail Occasionalism. Descartes holds that God is a direct efficient cause of every natural motion. Yet he does not take this to imply that bodies lack genuine causal powers. According to Descartes, God concurs with bodies to cause natural motion in such a way that both God and bodies are genuine, efficient causes of motion. I conclude by presenting an account of how Descartes's theory of body is compatible with the thesis that bodies have intrinsic active causal powers.     

Physicalism and Ontological Holism

The claim of this paper is that we should envisage physicalism as an ontological holism. Our current basic physics, quantum theory, suggests that, ontologically speaking, we have to assume one global quantum state of the world; many of the properties that are often taken to be intrinsic properties of physical systems are in fact relations, which are determined by that global quantum state. The paper elaborates on this conception of physicalism as an ontological holism and considers issues such as supervenience, realization of higher-order properties by basic physical properties, and reduction.     

The Need for a Revolution in the Philosophy of Science

There is a need to bring about a revolution in the philosophy of science, interpreted to be both the academic discipline, and the official view of the aims and methods of science upheld by the scientific community. At present both are dominated by the view that in science theories are chosen on the basis of empirical considerations alone, nothing being permanently accepted as a part of scientific knowledge independently of evidence. Biasing choice of theory in the direction of simplicity, unity or explanatory power does not permanently commit science to the thesis that nature is simple or unified. This current ‘paradigm’ is, I argue, untenable. We need a new paradigm, which acknowledges that science makes a hierarchy of metaphysical assumptions concerning the comprehensibility and knowability of the universe, theories being chosen partly on the basis of compatibility with these assumptions. Eleven arguments are given for favouring this new ‘paradigm’ over the current one. This revised version was published online in August 2006 with corrections to the Cover Date.
