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 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 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.

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 <span class='Hi'>time</span> in Book Δ of The Physics by asking whether <span class='Hi'>time</span> 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 <span class='Hi'>time</span>. First, I argue that the metaphysical and meta-philosophical presuppositions underlying most philosophy of <span class='Hi'>time</span> are deeply flawed. Second, that Aristotle provides us with a much more plausible alternative set of (...) presuppositions about the nature of <span class='Hi'>time</span>. The Aristotelian conception of <span class='Hi'>time</span> 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 <span class='Hi'>time</span> often raised in the context of contemporary physics and show how the Aristotelian perspective can resolve those puzzles.

This paper is a response to the preceding papers. It is maintained that American business is failing to live up to its obligations to society. One reason for this is acceptance of what De George calls the Myth of Amoral Business. Businessmen believe that morality is either not applicable to business or that business has a special morality of its own. Several arguments are advanced to show why this is not true. A second reason business is failing to fulfill its (...) obligations is that egoism seems to be an essential feature of capitalism. Harrington believes that this should be changed, but that attempts to change it are bringing about a more collectivist society. Kirk sees no need for change because he believes capitalism the best possible economic system. It is argued in reply that they are both mistaken because their analyses are based on outmoded ideologies which impede rather than aid us in solving problems caused by the irresponsibility of business.

For T any completion of Peano Arithmetic and for n any positive integer, there is a model of T of size $\beth_n$ with no (n + 1)-length sequence of indiscernibles. Hence the Hanf number for omitting types over T, H(T), is at least $\beth_\omega$ . (Now, using an upper bound previously obtained by Julia Knight H (true arithmetic) is exactly $\beth_\omega$ ). If T ≠ true arithmetic, then $H(T) = \beth_{\omega1}$ . If $\delta \not\rightarrow (\rho)^{ , then any completion of (...) Peano Arithmetic has a model of size δ with no set of indiscernibles of size ρ. There are similar results for theories strongly resembling Peano Arithmetic, e.g., ZF + V = L. (shrink)

A set X of nonnegative integers is computably enumerable (c.e.), also called recursively enumerable (r.e.), if there is a computable method to list its elements. Let ε denote the structure of the computably enumerable sets under inclusion, $\varepsilon = (\{W_e\}_{e\in \omega}, \subseteq)$ . We previously exhibited a first order ε-definable property Q(X) such that Q(X) guarantees that X is not Turing complete (i.e., does not code complete information about c.e. sets). Here we show first that Q(X) implies that X has (...) a certain "slowness" property whereby the elements must enter X slowly (under a certain precise complexity measure of speed of computation) even though X may have high information content. Second we prove that every X with this slowness property is computable in some member of any nontrivial orbit, namely for any noncomputable A ∈ ε there exists B in the orbit of A such that X ≤ T B under relative Turing computability (≤ T ). We produce B using the Δ 0 3 -automorphism method we introduced earlier. (shrink)

The significance of Machiavelli's political thinking for the development of modern republicanism is a matter of great controversy. This reassessment examines the character of Machiavelli's own republicanism by charting his influence on Marchamont Nedham, James Harrington, John Locke, Algernon Sidney, John Trenchard, Thomas Gordon, David Hume, the baron de Montesquieu, Benjamin Franklin, George Washington, John Adams, Thomas Jefferson, James Madison, and Alexander Hamilton. Concluding that although Machiavelli himself was not liberal, Paul Rahe argues that he did, nonetheless, (...) set the stage for the emergence of liberal republicanism in England. (shrink)

Ambition is a curiously neglected topic in ethics. It isn’t that philosophers have not discussed it. Plato, Aristotle, Seneca, Aquinas, Machiavelli, Harrington, Locke, Rousseau, Smith, Santayana and a number of others have discussed ambition. But it has seldom received more than a few paragraphs worth of analysis, in spite of the fact that ambition plays a central role in Western politics (one cannot be elected without it), and in spite of the fact that Machiavelli, Harrington, Locke and Rousseau (...) each considered it to be among the greatest threats to political security. The aim of this paper is to provide a long overdue analysis of ambition. The first part of the paper explores what ambition is. The second seeks to answer the question, “Is ambition a virtue or a vice?”. (shrink)

Modern republicanism - distinguished from its classical counterpart by its commercial character and jealous distrust of those in power, by its use of representative institutions, and by its employment of a separation of powers and a system of checks and balances - owes an immense debt to the republican experiment conducted in England between 1649, when Charles I was executed, and 1660, when Charles II was crowned. Though abortive, this experiment left a legacy in the political science articulated both by (...) its champions, John Milton, Marchamont Nehdham, and James Harrington, and by its sometime opponent and ultimate supporter Thomas Hobbes. This volume examines these four thinkers, situates them with regard to the novel species of republicanism first championed more than a century before by Niccolo Machiavelli, and examines the debt that he and they owed the Epicurean tradition in philosophy and the political science crafted by the Arab philosophers Alfarabi, Avicenna, and Averroes.

The role of ethics in organizational crisis management has received limited but growing attention. However, the majority of research has focused on applications of ethical theories to managing crisis events after they have occurred, as opposed to the implications of ethical theories for the primary prevention of these situations. The relationship between concepts derived from a contemporary ethic of care (resistance, voice, silence, connection) (Gilligan, C.: 1988, ‘Exit–voice Dilemmas in Adolescent Development’, in C. Gilligan, J. V. Ward and J. (...) M. Taylor (eds.) (Harvard University Press, Cambridge, MA), pp. 141–158, Gilligan, C.: 1990, ‘Preface’, in C. Gilligan, N. P. Lyons and T. J. Hanmer (eds.) (Harvard University Press, Cambridge, MA), pp. 6–29, Gilligan, C.: 1991, ‘Women’s Psychological Development: Implications for Psychotherapy’, in C. Gilligan, A. G. Rogers and D. L. Tolman (eds.) (Harrington Park Press, New York), pp. 5–32), and, concepts derived from a classic theory of organizational decline and recovery (exit, voice, loyalty) (Hirschman, A. O.: 1970, Exit, Voice, and Loyalty: Responses to Decline in Firms,Organizations, and States (Harvard University Press, Cambridge, MA)) is described. The relevance of these notions for signal detection and uptake in organizational crisis prevention is discussed. Implications for prevention are highlighted through consideration of a case involving organizational crisis, the explosion of the space shuttle Challenger. Directions for both business practice and future research are identified. (shrink)

Certain English writers of the seventeenth and early eighteenth centuries, whom scholars often associate with classical republicanism, were not, in fact, hostile to liberalism. Indeed, these thinkers contributed to a synthesis of liberalism and modern republicanism. As this book argues, Marchamont Nedham, James Harrington, Henry Neville, Algernon Sidney, and John Trenchard and Thomas Gordon, the co-authors of a series of editorials entitled Cato's Letters, provide a synthesis that responds to the demands of both republicans and liberals by offering (...) a politically engaged citizenry as well as the protection of individual rights. The book also reinterprets the writings of Machiavelli and Hobbes to show that each contributed in a fundamental way to the formation of this liberal republicanism. (shrink)
