In this paper, I defend a theory of local temporality, sometimes referred to as a point-present theory. This theory has the great advantage that it allows for the possibility of an open future without requiring any alterations to our standard understanding of special relativity. Such theories, however, have regularly been rejected out of hand as metaphysically incoherent. After surveying the debate, I argue that such a transformation of temporal concepts (i) is suggested by the indexical semantics of tense in a (...) relativistic universe, (ii) when properly understood easily withstands the usual accusations of metaphysical incoherence and (iii) leads naturally to a meta-philosophical position from which we can understand and escape the increasing sterility of debates between radical Parmenideans and radical Heracliteans in the philosophy of time.

Aristotle begins his famous discussion of time in Book Δ of The Physics by asking whether time belongs to “the things that exist.” In this paper I argue that Aristotle’s apparently ambiguous answer to this question holds one of the keys to clarifying contemporary philosophy of time . First, I argue that the metaphysical and meta-philosophical presuppositions underlying most philosophy of time are deeply flawed. Second, that Aristotle provides us with a much more plausible alternative set of presuppositions about the (...) nature of time . The Aristotelian conception of time as part of the subject matter of physics or “the philosophy of nature” is particularly illuminating. Finally, I examine several issues about the nature and reality of time often raised in the context of contemporary physics and show how the Aristotelian perspective can resolve those puzzles.

James Harrington (1611-77) was a pioneer in applying the methods of Machiavelli and other civic humanists to English political society and its landed structure. In the century after his death, his ideas were adapted to become an important ingredient in the vocabulary of both English and American political opposition to the methods of Hanoverian parliamentary monarchy. There has been no complete edition of Harrington's writings since 1771, or of Oceana, his best-known work, since 1924. This is a modernised edition, and (...) includes all of his prose works on political subjects. The critical introduction attempts to revalue the evidence concerning Harrington's life and writings, to locate them in the context of Civil War, Commonwealth and Puritan thinking and to trace the development of Harringtonian and neo-Harringtonian ideology during subsequent generations.

This paper will argue that the puzzles about instantaneous velocity, and rates of change more generally, are the result of a failure to recognize an ambiguity in the concept of an instant, and therefore of an instantaneous state. We will conclude that there are two distinct conceptions of a temporal instant: (i) instants conceived as fundamentally distinct zero-duration temporal atoms and (ii) instants conceived as the boundary of, or between,temporally extended durations. Since the concept of classical instantaneous velocity is well- (...) defined only on the second conception of instants, we will conclude that this distinction allows us to avoid the above dilemma. If instantaneous velocity is well-defined then the states of a system at various instants are not logically distinct and thus we cannot generate Zeno’s paradox. However, if we assume that the instants are metaphysically distinct, then instantaneous velocity is not well-defined and thus the second horn of the dilemma about the causal-explanatory role of instantaneous velocity cannot be generated.

This paper argues that the Einstein-Minkowski space-time of special relativity provides an adequate model for classical tense logic, including rigorous definitions of tensed becoming and of the logical priority of proper time. In addition, the extension of classical tense logic with an operator for predicate-term negation provides us with a framework for interpreting and defending the significance of future contingency in special relativity. The framework for future contingents developed here involves the dual falsehood of non-logical contraries, only one of which (...) becomes true. This has several methodological, metaphysical and physical advantages over the alternative traditional frameworks for handling future contingents. (shrink)

This essay introduces a formal structure to model the indeterminacy of the future in Einstein-Minkowski space-time. We consider a first-order language, supplemented with an operator for predicate-term negation, and defend the claim that such an operation provides an appropriate model for the indeterminacy of future contingents. In the final section, it is proved that given a language otherwise adequate to represent a physical theory, at least some of the predicates of that language are indeterminate when the future is not causally (...) determined by the present and the past.

Time: A Philosophical Introduction presents the philosophy of time as the central debate between being and the becoming.This core theme brings together the key topics, debates and thinkers, making ideas such as Zeno's paradoxes, the experience of change and temporal flow and the direction and shape of time and time travel, clear and understandable. Alongside a glossary and detailed timeline to further enhance study and understanding, each chapter features: • Extensive lists of further reading in both primary and secondary sources (...) • A chronological listing of key figures, brief biographical data and references • True/false questions, matching, multiple choice, and short answer questions Time is a central philosophical subject, impacting on all many different aspects of philosophy. More technical discussions of issues from mathematics, logic and physics are separated into Technical Interludes,allowing readers to choose their level of difficultly. As a result this comprehensive introduction is essential reading for upper-level undergraduates studying the philosophy of time,metaphysics or the philosophy of science. (shrink)

In Three Mystics Walk into a Tavern, Jalal ad-Din Rumi, Moses de León, and Meister Eckhart— three of the greatest mystics of all time—meet for an imaginary conversation that will inspire individuals of the twenty-first century to find their own spirituality and realize that everyone can be a mystic.

Excerpt from The Political Writings of James Harrington: Representative Selections Finally, I should like to express my deep gratitude to three scholars who have generously helped me in the preparation of this volume: Carl J. Friedrich, of Harvard University, under whose kind and expert guidance I first undertook the study of James Harrington's political thought; Cecil Driver, of Yale University, who tried (with scant success, I fear) to give my prose style something of the grace and elegance that distinguish his (...) own; and Harry Hubbell, of Yale, whose erudi tion made the identification of even the most obscure classical passages seem easy.
