This volume brings together a distinguished, international list of scholars to explore the role of the learner's intention in knowledge change. Traditional views of knowledge reconstruction placed the impetus for thought change outside the learner's control. The teacher, instructional methods, materials, and activities were identified as the seat of change. Recent perspectives on learning, however, suggest that the learner can play an active, indeed, intentional role in the process of knowledge restructuring. This volume explores this new, innovative view of conceptual (...) change learning using original contributions drawn from renowned scholars in a variety of disciplines. The volume is intended for scholars or advanced students studying knowledge acquisition and change, including educational psychology, developmental psychology, science education, cognitive science, learning science, instructional psychology, and instructional and curriculum studies.

The employment of mythological language and imagery by an Epicurean poet - an adherent of a system not only materialist, but overtly hostile to myth and poetry - is highly paradoxical. This apparent contradiction has often been ascribed to a conflict in the poet between reason and intellect, or to a desire to enliven his philosophical material with mythological digressions. This book attempts to provide a more positive assessment of Lucretius' aims and methodology by considering the poet's attitude to myth, (...) and the role which it plays in the De Rerum Natura, against the background of earlier and contemporary views. The author suggests that Lucretius was not only aware of the tension between his two roles as philosopher and poet, but attempted to resolve it by developing his own, Epicurean poetic, together with a bold and innovative theory of the origins and meaning of myth.

Our paper ‘A new cosmological argument’ gave an argument for the existence of God making use of the weak Principle of Sufficient Reason (W-PSR) which states that for every proposition p, if p is true, then it is possible that there is an explanation for p. Recently, Graham Oppy, as well as Kevin Davey and Rob Clifton, have criticized the argument. We reply to these criticisms. The most interesting kind of criticism in both papers alleges that the W-PSR can be (...) justifiably denied by the atheist, and constitutes no improvement on the strong Principle of Sufficient Reason (S-PSR) which claims that every true proposition in fact has an explanation. The criticism is predicated on the fact that it can be shown that the W-PSR entails the S-PSR. We argue that the W-PSR's plausibility remains despite the criticisms. From this it can be seen to follow that the entailment relation between the W-PSR and the S-PSR gives one reason to believe the S-PSR. (shrink)

John Conington was a towering figure in Victorian scholarship, not least because of his remarkably sensitive and literate commentaries on Virgil’s _Aeneid. _The three-volume cloth edition of _The Works of Virgil_, begun by Conington in 1852, has been unavailable for over a century, except in rare second-hand sets. Now, for the first time, the whole of Conington’s work is being reissued in a set of six paperback volumes. Each volume includes a new introduction by an established scholar, setting Conington's commentary (...) in context, as well as a general introduction to Conington’s work by Philip Hardie, who offers a fresh appreciation of the work.

The overwhelming importance of Lucretius' De Rerum Natura for the interpretation of the Georgics is recognized by almost all critics. As W. Y. Sellar expressed it over a hundred years ago, ‘the influence, direct and indirect, exercised by Lucretius on the thought, composition and even the diction of the Georgics was perhaps stronger than that ever exercised, before or since, by one poet on the work of another’. Richard Thomas' recent commentary attempts to play down the extent of this influence, (...) contending that ‘the debt of Virgil to Lucretius in the Georgics is predominantly formal’, and manifests itself chiefly on a verbal level, whereby the poet seeks ‘to create a didactic appearance for his poem’. The aim of this paper is to reassert the pervasive importance of Lucretian ideas, as well as Lucretian language, throughout the poem, and particularly in Virgil's presentation of the physical and metaphysical relationships between man and beast.

R. M. Adams’s essay, “Must God Create the Best?” can be interpreted as offering a theodicy for God’s creating morally less perfect beings than he could have created. By creating these morally less perfect beings, God is bestowing grace upon them, which is an unmerited or undeserved benefit. He does so, however, in advance of the free moral misdeeds that render them undeserving. This requires that God have middle knowledge, pace Adams’s version of the Free Will Theodicy, of what would (...) result from his actualization of possible free persons. It is argued that God’s possession of such middle knowledge negates the freedom of created beings, since God completely determines every action of every created person. And since they are not free, they cannot qualify as morally unmeritorious or undeserving. And, with that, Adams’s theodicy of grace-in-advance collapses. (shrink)

In a series of articles, the most extensive of which are [9] and [10], Carl R. Kordig has attacked the "new empiricism" of the late Norwood R. Hanson, P. K. Feyerabend, Thomas S. Kuhn, and Stephen E. Toulmin. While there are differ- ences among the views of these philosophers, they agree at least on the following claims: (1) scientific method does not proceed inductively from neutral observations because (a) observations are not free of interpretation; and (b) scientists, as a matter (...) of history, have not used induction as the means of arriving at scientific laws; and (2) the key to scientific progress is the discovery of theories, hypotheses, or paradigms which order phenomena and influence the ways in which data are experienced. While Kordig admits that the new empiricism has the valuable effect of underscoring the truth that scientific revolutions do not consist merely in finding new facts or in paying closer attention to already known facts, contrary to the new view, he maintains that observations must be and are neutral ([9], pp. 478-479). Kordig contends against the new empiricists that if observations are not neutral but theory-laden, then it is impossible to test, compare and verify theories. Conse- quently, Kordig concludes that the new empiricist view implies that scientific progress is impossible ([9], pp. 470-471; [10j, p. 470). In opposition to their view, Kordig maintains that observations are neutral and independent of theories (and this was the insight of the logical empiricists) ([10], p. 468); and moreover, observa- tions must be neutral to and independent of theory in order that (a) differing theories may be truly said to compete and (b) the observations may be the basis of testing and deciding between competing theories.

In simplified form, the argument that I am defending holds that the incompatibility of our freedom with determinism follows from the conjunction of (1) a plausible supervenience claim which says that whether a human agent is free depends only on what happens during the agent’s life and (2) a freedom-cancellation principle of Richard Gale which says that an agent is not free if all of her actions are intentionally brought about by another agent. Improved versions of (1) and (2) are (...) also considered. (shrink)

Idealogically motivated responses to the Bishops' Letter have heightened the divisiveness of subsequent dialogue at the expense of its rigor. Schumpeter's metaphor of creative destruction provides a vehicle for reconciliation between advocates of politics and markets. His most distinguishing characteristic of capitalism extols its productive and dynamic properties. It underscores its relentless and unmanageable side that transforms institutional structures as well. The capitalist engine is driven by a perennial gale that creates and destroys at the same time; thus there is (...) a necessary role for both entrepreneurs and planners in a mixed economy. The bishops' call for collaboration is also subject to the Schumpeterian metaphor. Major process changes without new institutional forms are inconsistent with the historical experience of U.S. pluralist society. (shrink)

Ronald Dworkin's theory of law forges a close connection between questions about the truth of propositions of law and the question of political obligation: law as integrity is a theory of legal practice that purports to explain, not only how the content of law is determined, but also why the law—in ordinary cases—imposes an obligation of obedience. The theory (as presented) is ultimately incoherent. If we accept Dworkin's theory of the grounds of law we are obliged to reject his claims (...) about its force; alternatively, if we accept his view of the force of law, we must reject his theory about its grounds: he cannot be correct about both force and grounds. Dworkin supposes that, in extraordinary cases, the force of law is cancelled or overridden; but the relevant considerations of justice are wholly internal to our identification of the content of law. Consistently elaborated, integrity denies the offending requirements legal status: lex injusta non est lex. (shrink)

The lively debate over the constitutional foundations of judicial review has been marred by a formalism which obscures its point and value.ed from genuine issues of substance, the rival positions offer inadequate accounts of the legitimacy of judicial review; constitutional theory must regain its connection with questions of political principle and moral value. Although the critics of ultra vires have rightly emphasized the foundational role of the common law, they have misconceived its nature and implications. On the one hand, they (...) have invited the charge of judicial supremacism by marginalizing the role of legislative intent; on the other, their affirmation of absolute parliamentary sovereignty (within the context of this debate) undermines the critique of ultra vires. In substance, therefore, the rival camps occupy essentially the same ground, equally trapped by a formalism that entrenches a stark confrontation between parliamentary sovereignty and the rule of law. A conception of shared sovereignty, or interdependent sovereignties, provides a better foundation for judicial review. (shrink)

Heuristics of evolutionary biology dictate that phylogenetically older processes are inherently more stable and resilient to disruption than younger processes. On the grounds that non-declarative behaviour emerged long before declarative behaviour, Reber argues that implicit learning is supported by neural processes that are evolutionarily older than those supporting explicit learning. Reber suggested that implicit learning thus leads to performance that is more robust than explicit learning. Applying this evolutionary framework to motor performance, we examined whether implicit motor learning, relative to (...) explicit motor learning, conferred motor output that was resilient to physiological fatigue and durable over time. In Part One of the study a fatigued state was induced by a double Wingate Anaerobic test protocol. Fatigue had no affect on performance of participants in the implicit condition; whereas, performance of participants in the explicit condition deteriorated significantly. In Part Two of the study a convenience sample of participants was recalled following a one-year hiatus. In both the implicit and the explicit condition retention of performance was seen and, contrary to the findings in Part One, so was resilience to fatigue. The resilient performance in the explicit condition after one year may have resulted from forgetting or from consolidation of declarative knowledge as implicit memories. In either case, implicit processes were left to more effectively support motor performance. (shrink)

R. S. Bluck’s engaging volume provides an accessible introduction to the thought of Plato. In the first part of the book the author provides an account of the life of the philosopher, from Plato’s early years, through to the Academy, the first visit to Dionysius and the third visit to Syracuse, and finishing with an account of his final years. In the second part contains a discussion of the main purpose and points of interest of each of Plato’s works. There (...) is a chapter on Plato’s central doctrine, the Theory of Ideas, and a translation of Plato’s _Seventh Letter_, which not only provides valuable additional material for the study of Plato’s thought but also contains a vivid account of many incidents in Plato’s life.

My analysis of the constitutional foundations of judicial review has been criticized by Paul Craig; but his objections confuse the ‘constructive’ account of legislative intent I defend with the ‘literal’ conception (reflecting the views of individual legislators) I expressly repudiate. He thinks we must choose between legislative intent, literally conceived, and common law principle. This mistake exemplifies the peculiar character of Craig's ‘common law model’ of judicial review, in which the requirements of the rule of law, on one hand, and (...) the relevant statute, on the other, exist in separate mental worlds. That model is conceptually confused, rejecting the doctrine of ultra vires that (unqualified) legislative supremacy entails, and ultimately grounded in a wholly implausible view of the relationship between common law and statute. It subordinates both statutory text and purpose to common law doctrine, treated as largely self-contained and impervious to context. It ignores the interdependence of legislative and judicial power, impeding a genuine integration of statutory command and common law principle. (shrink)

Adhering to the traditional concept of omniscience lands Gale in the incoherence Grim’s Cantorian arguments reveal in talk of “all propositions.” By constructing variants and extensions of Grim’s arguments, I explain why various ways out of the incoherence are unacceptable, why theists would do better to adopt a certain revisionary concept of omniscience, and why the Cantorian troubles are so deep as to be troubles as well for Gale’s Weak PSR. I conclude with some brief reflections on method, suggesting that (...) we pursue the full implications of Gale’s own revisionary remarks and replace his method of analytic argumentation with non-analytic revisionary theory-construction.

Plant protection problems are simulated by a system of ordinary differential equations with given initial conditions. The sensitivity and resistance of pathogen subpopulations to fungicide mixtures, fungicide weathering, plant growth, etc. are taken into consideration. The system of equations is solved numerically for each set of initial conditions and parameters of the disease and fungicide applications. Optimization algorithms were investigated and a computer program was developed for optimization of these solutions. 14 typical cases of the disease were simulated and optimized (...) in order to determine optimal fungicide treatments. The optimized strategy for fungicide application differs considerably from the commonly used method and seems to be an important new principle in plant protection. The approach developed in this study may be useful for a wide spectrum of purposes in the simulation of leaf diseases. It may also help the biologist to decrease or pinpoint experimental work and analyze its results and is perspective for plant disease control. (shrink)

"Williams's masterful translation satisfies (at last!) a long-standing need. There are lots of good translations of Augustine's great work, but until now we have been forced to choose between those that strive to replicate in English something of the majesty and beauty of Augustine's Latin style and those that opt instead to convey the careful precision of his philosophical terminology and argumentation. Finally, Williams has succeeded in capturing both sides of Augustine's mind in a richly evocative, impeccably reliable, elegantly readable (...) presentation of one of the most impressive achievements in Western thought--Augustine's Confessions." --Scott MacDonald, Professor of Philosophy and Norma K.
