This book is about spacetime, and how, in General Relativity, it performs its widely accepted role of explaining all the phenomena of gravity. Space and time have long been contentious presences in theories of mechanics because of their metaphysical peculiarities. Philosophical worries continue to fog a clear understanding of just how spacetime performs this role. In early sections of his revolutionary paper of 1916, Einstein claimed that his use of a new style of formulation removes "the last remnant of physical objectivity from space and time". His satisfaction in banishing these metaphysical anxieties was evident. However in 1917 it was shown his claim was ungrounded. He readily accepted the criticism: it left intact all the maths and physics of the theory. These amply justify the widespread, orthodox view of spacetime's fundamental role in the theory. Einstein banished no demon but rather released a genie - spacetime. However, his hostility continued, resulting in attempts to rewrite the role of spacetime. These had some later influence but never caught on. Einstein set supreme importance on the role of imagination in scientific theory and valued it as his most significant gift. In science, perhaps in culture generally, relativity is unsurpassed in its imaginative conceptual daring. Yet he and others paused at its metaphysical novelty and radicalism: hostility to spacetime persists. This book presents an unqualified philosophical defence of the conceptual coherence and uniqueness of spatiotemporality. It offers an alternative to the relationist/substantivalist dilemma; it explains Minkowski's derivation of spacetime without the light postulate; it defends, clarifies and stresses the deep role of spacetime in the standard novelties of both relativity theories. A study of spacetime in relativity shows how an insubstantial entity can nevertheless be concrete. That solves the metaphysical worry over its intelligibility and reveals it as fundamental to ontology.

In 1919 the Prussian Ministry of Science, Arts and Culture opened a dossier on "Einstein's Theory of Relativity." It was rediscovered by the author in 1961 and is used in conjunction with numerous other subsequently identified 'Einstein' files as the basis of this fascinating book. In particular, the author carefully scrutinizes Einstein's FBI file from 1950-55 against mostly unpublished material from European including Soviet sources and presents hitherto unknown documentation on Einstein's alleged contacts with the German Communist Party and the Comintern. Siegfried Grundmann's thorough study of Einstein's participation on a committee of the League of Nations, based on archival research in Geneva, is also new. This book outlines Einstein's image in politics and German science policy. It covers the period from his appointment as a researcher in Berlin to his fight abroad against the "boycott of German science" after World War I and his struggle at home against attacks on "Jewish physics" of which he was made a prime target. An important gap in the literature on Einstein is thus filled, contributing much new material toward a better understanding of Einstein's so rigorous break with Germany.

At this threshold of our species' evolution there is an increasing recognition that new approaches are needed to create the radical changes necessary for humanity to survive on this planet. Business is not exempt-it's at the center of this radical change. Business can even be the lynchpin around which the rest of social transformation takes place, and can lead the way as we relinquish our addiction to control and to the extreme competitiveness that has paralyzed us and prevented us from uniting to address the urgency of the crisis at hand. In this anthology, some of the best-selling business authors of today infuse their visions, experiences, and insights into the ongoing conversation about how to find solutions to seemingly impossible challenges. The guiding principles for the book are derived from the inspiring, timeless wisdom of Albert Einstein, a man who modeled the ability to be a channel for intuitive, imaginative, and collective intelligence. From that realm we can draw on collective intelligence to re-invent ourselves and transform business.

In 1908, three years after Einstein first published his special theory of relativity, the mathematician Hermann Minkowski introduced his four-dimensional “spacetime” interpretation of the theory. Einstein initially dismissed Minkowski’s theory, remarking that “since the mathematicians have invaded the theory of relativity I do not understand it myself anymore.” Yet Minkowski’s theory soon found wide acceptance among physicists, including eventually Einstein himself, whose conversion to Minkowski’s way of thinking was engendered by the realization that he could profitably employ it for the formulation of his new theory of gravity. The validity of Minkowski’s mathematical “merging” of space and time has rarely been questioned by either physicists or philosophers since Einstein incorporated it into his theory of gravity. Physicists often employ Minkowski spacetime with little regard to the whether it provides a true account of the physical world as opposed to a useful mathematical tool in the theory of relativity. Philosophers sometimes treat the philosophy of space and time as if it were a mere appendix to Minkowski’s theory. In this critical study, Joseph Cosgrove subjects the concept of spacetime to a comprehensive examination and concludes that Einstein’s initial assessment of Minkowksi was essentially correct.

Anselm of Canterbury gave the first modal "ontological" argument for God's existence. Yet, despite its distinct originality, philosophers have mostly avoided the question of what modal concepts the argument uses, and whether Anselm's metaphysics entitles him to use them. Here, Brian Leftow sets out Anselm's modal metaphysics. He argues that Anselm has an "absolute", "broadly logical", or "metaphysical" modal concept, and that his metaphysics provides acceptable truth makers for claims in this modality. He shows that his modal argument is committed (in effect) to the Brouwer system of modal logic, and defends the claim that Brouwer is part of the logic of "absolute" or "metaphysical" modality. He also defends Anselm's premise that God would exist with absolute necessity against all extant objections, providing new arguments in support of it and ultimately defending all but one premise of Anselm's best argument for God's existence.
