A method originally conceived by Bohm for abstracting key features of the metric geometry from an underlying spinor ordering is generalized to the projective geometry. This allows the introduction of the spinor into a projective context and the definition of an associated geometric algebra. The projective spinor may then be regarded as defining a pregeometry for the projective space. |

In this paper I present the Discrete Space-Time Thesis, in a way which enables me to defend it against various well-known objections, and which extends to the discrete versions of Special and General Relativity with only minor difficulties. The point of this presentation is not to convince readers that space-time really is discrete but rather to convince them that we do not yet know whether or not it is. Having argued that it is an open question whether or not space-time (...) |

Spacetime substantivalism leads to a radical form of indeterminism within a very broad class of spacetime theories which include our best spacetime theory, general relativity. Extending an argument from Einstein, we show that spacetime substantivalists are committed to very many more distinct physical states than these theories' equations can determine, even with the most extensive boundary conditions. |

Two versions of the GRW “hitting” model for explicit wavefunction collapse, which are consistent with preserving the symmetry of the wavefunction, are considered. The predictions of the models for excitation of bound systems are calculated and compared with experiment and with the predictions of other similar models. It is shown that our preferred model strongly supports the idea that collapse, if it occurs, has gravitational origin. |

This book espouses a theory of scientific realism in which due weight is given to mathematics and logic. The authors argue that mathematics can be understood realistically if it is seen to be the study of universals, of properties and relations, of patterns and structures, the kinds of things which can be in several places at once. Taking this kind of scientific platonism as their point of departure, they show how the theory of universals can account for probability, laws of (...) |

In his classic work, _Wholeness and the Implicate Order_, David Bohm develops a theory of quantum physics which treats the totality of existence, including matter and consciousness, as an unbroken whole. David Bohm presents a rational and scientific theory which explains cosmology and the nature of reality; written clearly, and without the use of technical jargon, it is essential reading for those interested in physics, philosophy, psychology and the connection between consciousness and matter. David Bohm was one of the foremost (...) |

David Bohm was one of the foremost scientific thinkers and philosophers of our time. Although deeply influenced by Einstein, he was also, more unusually for a scientist, inspired by mysticism. Indeed, in the 1970s and 1980s he made contact with both J. Krishnamurti and the Dalai Lama whose teachings helped shape his work. In both science and philosophy, Bohm's main concern was with understanding the nature of reality in general and of consciousness in particular. In this classic work he develops (...) |

Since its publication in 1959, Individuals has become a modern philosophical classic. Bold in scope and ambition, it continues to influence debates in metaphysics, philosophy of logic and language, and epistemology. Peter Strawson's most famous work, it sets out to describe nothing less than the basic subject matter of our thought. It contains Strawson's now famous argument for descriptive metaphysics and his repudiation of revisionary metaphysics, in which reality is something beyond the world of appearances. Throughout, Individuals advances some highly (...) |

This report reviews what quantum physics and information theory have to tell us about the age-old question, How come existence? No escape is evident from four conclusions: (1) The world cannot be a giant machine, ruled by any preestablished continuum physical law. (2) There is no such thing at the microscopic level as space or time or spacetime continuum. (3) The familiar probability function or functional, and wave equation or functional wave equation, of standard quantum theory provide mere continuum idealizations (...) |

Quantum mechanics is a subject that has captured the imagination of a surprisingly broad range of thinkers, including many philosophers of science. Quantum field theory, however, is a subject that has been discussed mostly by physicists. This is the first book to present quantum field theory in a manner that makes it accessible to philosophers. Because it presents a lucid view of the theory and debates that surround the theory, An Interpretive Introduction to Quantum Field Theory will interest students of (...) |

Bertrand Russell remains one of the greatest philosophers and most complex and controversial figures of the twentieth century. Here, in this frank, humorous and decidedly charming autobiography, Russell offers readers the story of his life – introducing the people, events and influences that shaped the man he was to become. Originally published in three volumes in the late 1960s, _Autobiography_ by Bertrand Russell is a revealing recollection of a truly extraordinary life written with the vivid freshness and clarity that has (...) |

This paper is written from the perspective of a computer scientist and addressed to theoretical physicists. As a consequence it may seem somewhat unusual, but rest assured, everything is really quite simple! The point of this paper is that the study of certain phenomena from computer science suggests that there are computer systems (cellular automata) that may be appropriate as models for microscopic physical phenomena. Cellular automata are now being used to model varied physical phenomena normally modelled by wave equations, (...) |

If I were to drop an apple, then it would fall. It is not possible that it would fly upwards. It is necessary that it would fall. I think these statements are true, but at the same time I believe that it is not logically necessary that the apple would fall. I believe that there is in nature a kind of necessity weaker than logical necessity: natural necessity. |
