Identifying the missing or unstated premisses of arguments is important, because their logical quality depends on them. Textbook authors regard enthymematic syllogisms (e.g., "Elvis is a man, so Elvis is mortal") as having an unstated premiss - the major premiss (e.g., "All men are mortal"). They are said to be such because these syllogisms become formally valid when the major premiss is added (i.e., it is a gap-filler). I argue that unstated major premises are not gap-fillers: they support a part (...) of the argument that is already given implicitly - the inference claim ("If the premisses are true then the conclusion is true"). As such, their logical status is the same as that of an unstated proposition that supports the minor premiss, which is not part of the argument. Therefore, the so-called "major premiss" is not an unstated premiss of the enthymeme. (shrink)

This article describes some historical precursors that led to William James’s participation in the Hibbert Lectures and his subsequent publication of A Pluralistic Universe. William James viewed the monism–pluralism issue as the greatest issue the human mind can frame, and he returned to this issue again and again in his psychological and philosophical works. The Hibbert Lectures afforded an opportunity to explore the problem of monism and pluralism in a broadly religious or spiritual context. We describe James’s logical and experiential (...) attacks on monistic thinkers, his seemingly paradoxical introduction of Gustav Fechner’s panpsychism to English-speaking philosophers, and his spirited defense of pluralism. We conclude by discussing the relevance of James’s pluralism for current questions of unification in psychology. (shrink)

This book emphasizes the compatibility of Aristotelianism, Austrian economics, and Ayn Rand's Objectivism, arguing that particular ideas from these areas can be integrated as a potential paradigm of human flourishing and happiness in a free society. It constructs an understanding from various disciplines into a clear, consistent, and systematic whole.

Understanding the nature of errors in a simple, rule‐based task—programming a VCR—required analyzing the interactions among human cognition, the artifact, and the task. This analysis was guided by least‐effort principles and yielded a control structure that combined a rule hierarchy task‐to‐device with display‐based difference‐reduction. A model based on this analysis was used to trace action protocols collected from participants as they programmed a simulated VCR. Trials that ended without success (the show was not correctly programmed) were interrogated to yield insights (...) regarding problems in acquiring the control structure. For successful trials (the show was correctly programmed), steps that the model would make were categorized as matches to the model; steps that the model would not make were violations of the model. The model was able to trace the vast majority of correct keystrokes and yielded a business‐as‐usual account of the detection and correction of errors. Violations of the model fell into one of two fundamental categories. The model provided insights into certain subcategories of errors; whereas, regularities within other subcategories of error suggested limitations to the model. Although errors were rare when compared to the total number of correct actions, they were important. Errors were made on 4% of the keypresses that, if not detected, would have prevented two‐thirds of the shows from being successfully recorded. A misprogrammed show is a minor annoyance to the user. However, devices with the approximate complexity of a VCR are ubiquitous and have found their way into emergency rooms, airplane cockpits, power plants, and so on. Errors of ignorance may be reduced by training; however, errors in the routine performance of skilled users can only be reduced by design. (shrink)

Plato, and a wide variety of ancient, Arabic, and medieval Platonisms had a significant influence on Aquinas. The Corpus, with its quasi-Apostolic origin for Aquinas, was his most authoritative and influential source of Neoplatonism. His most influential early sources of Platonism came from Aristotle and Augustine, that is besides the Dionysian Corpus and the Liber. Aquinas greatly acknowledged the Neoplatonic, and the Peripatetic, commentaries and paraphrases he gradually acquired, because they enabled getting to the Hellenic sources. A great part of (...) Aquinas's last writing was devoted to explicating Aristotle's works including the Liber de causis, which was attributed to him. Aquinas wished to understand the philosophical schools such as their characters, the differences between and within them, their memberships, influences, histories, and the extent to which they are complementary. Aquinas gave an extended treatment of the history of philosophy, including lists of differences and agreements between Plato and Aristotle, beginning with ‘the opinions of the ancients and of Plato’ in his On Separate Substances. When Aquinas treated Aristotle in On Separate Substances, he did not leave his Neoplatonic framework behind. There is much more in On Separate Substances concerning the numbers, including an elaborate reasoning that saves the verbally opposed positions of both Proclus and Dionysius. (shrink)

This chapter considers the different forms of natural theology in the Patristic Period, first examining the Stoic Middle Platonism of Philo Judaeus and Josephus. In Philo – uniting Plato's and Moses' genesis, and thus connecting God, the cosmos, and the human in the opposite way to the one taken by Lucretius in his De Rerum Natura – we encounter most of the forms natural theology took in the period. We find not only that there is no operation of pure nature (...) abstracted from the divine activity but also that physics leads to theology, and that nature, the human, and community depend on gifts given beyond them from above. The philosophies of Boethius, John Scottus Eriugena, and Augustine are also discussed. (shrink)

The Augustinian text is being radically rewritten by contemporary theologians to render it compatible with various proposals for a postmodern Christianity. The proximate stimulus is Derrida's deconstruction of the argument of the Confessions. What is positive and what is wanting in his appropriation of the Augustinian dialectic is reviewed, as also what can and cannot be seen of the historical Augustine from within the purview of a postmodern theology.

For Radical Orthodoxy participatory poiēsis is the only form of authentic postmodern theology and determines its dependence upon, as well as the character of, its narrative of the history of philosophy. Th is article endeavors to display how the polemical anti-modernism of the movement results in a disregard for the disciplines of scholarship, so that ideological fables about our cultural history pass for theology. Because of the Radical Orthodox antipathy to philosophy, its assertions cannot be proven rationally either in principle (...) or in fact, and its followers are reduced to accepting its stories on the authority of their tellers. The moral and rational disciplines are replaced with a postmodern incarnational neo-Neoplatonism in which the First Principle and sensual life are immediately united, without themediation of soul or mind. With this disappearance of theoria, surrender to the genuinely other, or even attentive listening, become impossible. (shrink)

Recent philosophical and theological writing on Augustine in France, England and North America is sharply divided between readings which serve either a historicist, anti-metaphysical, postmodern retrieval or an ahistorical, metaphysical, modern reassertion. The postmodern retrieval begins from a Heideggerian «end of metaphysics» and goes at least some distance with Jacques Derrida's development of its consequences. This essay starts from engagements with Augustine by Derrida and Jean-Luc Marion, moving then to Rowan Williams on the De trinitate, read to prevent comparison with (...) Descartes' Meditations, and considers how Williams relates Augustine to Plotinus. The opposed modernist interpretation appears in Stephen Menn's Descartes and Augustine, which sees a continuity between Plotinus, Augustine and Descartes. Finally, the essay treats Plotinus and Augustine on God and self-knowledge, maintaining that Augustine's De trinitate is better understood from within a modern ahistorical stance which, within metaphysics, places Augustine together with Plotinus and Descartes. This view better captures his difference from Plotinus than the alternative postmodern perspective tending to assimilate Augustine to Plotinus. (shrink)

The array seen when saccading across a point light source blinking in the dark is displaced in the direction of the saccade. This displacement reflects an abrupt shift of spatiotopic coordinates that precedes the actual eye movement. The extraretinal signal mediating this discrete shift appears to be an oculomotor reference signal, specifying intended eye orientation, that changes discretely before saccades.

This paper is both an essay and a critique. It questions whether the ancient Greeks responded to heroic or devotional sculpture in any significantly different way than people in later ages, including our own, do. Questioned, too, is whether ancient sculpture or sculpture at any time as to its coming into being can be explained by linguistics, such as, in this case, by Roman Jakobson's notion that all linguistic models are based on one of two models: either on similarity (metaphoric) (...) or on contiguity (metonymic: the name of one thing used in place of another associated with or suggested by it).

Like earthquakes and volcanic eruptions, the current international monetary crisis—bank failures and a collapse of markets worldwide—was not sufficiently predictable to preempt with defensive action. One would think that history's experiences with sudden breakdowns in global economics would have taught the modern world enough lessons to assure that economic intelligence would have tightened the reins of investors and speculators over the last decade of runaway optimism. But history has never been a good teacher—better said, people have rarely been good students (...) of history's lessons in cause and effect. Still, it makes sense, as with this essay, that we look back on such financial follies of the past, as epitomized by Holland's tulipmania, and take comfort in finding that our follies are just enough different from historical ones to at least claim them as our very own.
