In two studies, we explored the frequency and phenomenology of musical imagery. Study 1 used retrospective reports of musical imagery to assess the contribution of individual differences to imagery characteristics. Study 2 used an experience sampling design to assess the phenomenology of musical imagery over the course of one week in a sample of musicians and non-musicians. Both studies found episodes of musical imagery to be common and positive: people rarely wanted such experiences to end and often heard music that (...) was personally meaningful. Several variables predicted musical imagery, including personality, musical preferences, and positive mood. Musicians tended to hear musical imagery more often, but they reported less frequent episodes of deliberately-generated imagery. Taken together, the present research provides new insights into individual differences in musical imagery, and it supports the emerging view that such experiences are common, positive, and more voluntary than previously recognized.

This paper pursues two tasks: first, to criticize a number of prominent contemporary interpretations of the Pyrrhonism of Sextus Empiricus, especially Jonathan Barnes’s; and second, to outline an alternative interpretation of Sextus that (a) reconciles the opposing sides of the long-standing dispute over the scope of Pyrrhonian suspension of judgment, and (b) suggests a sympathetic alternative to some of the most influential accounts of the Pyrrhonian way of life.

The author assures readers that Chris Matthew Sciabarra has met all Aristotelian requirements in full, providing not one but two definitions of “dialectics,” which, as the art of context-keeping, is indeed an essential part of Ayn Rand's philosophical method. He shows how Sciabarra's definitional process compares quite favorably in terms of timeliness, transparency, and benevolence to that of Rand and other Objectivists, and notes that Sciabarra's overriding concern, notwithstanding his obvious great respect for Rand's substantive philosophical achievements, has been to (...) identify and clarify the methods she and other thinkers have used to profound benefit.

This bibliography constitutes the most extensive compilation of references on Nathaniel Branden yet published.

Clear-eyed and foundational, Roger Olson's The Essentials of Christian Thought outlines the most basic, necessary principles of a Christian outlook on the world---principles without which no thinking can properly be viewed as Christian.

The author explains how Rand was absolutely correct in saying that Aristotle “stated the formula” of the Law of Identity. He corrects long-standing faulty Thomist criticisms on this issue and gives due credit to thinkers such as Antonius Andreas, Leibniz, and William Hamilton. The author further contends that the gradual shift in Objectivist usage of the Law of Identity tacitly ratifies these erroneous criticisms and has actually contributed to the failure of Objectivist thinkers to develop Rand's concept theory into a (...) valid model of propositions and syllogisms.

The author discusses how Rand’s largely underdeveloped concept of the “dual-aspect objective,” first introduced in the 1960s, is vital for understanding how knowledge is grounded in reality. He defines it, then applies it to perception and introspection, and to concepts, propositions, and syllogisms. The author also defines content of awareness, carefully distinguishing it from both object and form of awareness, and applies those distinctions throughout. In addition, he discusses how truth is both dual-aspect and contextual, and he extends his discussion (...) in Part 1 of Rand’s “unit-perspective,” showing how units, too, have a dual-aspect, even on the level of syllogisms. (shrink)

The author contends that the Objectivist epistemology has lacked a viable model of propositional knowledge for nearly fifty years, due to neglect of Rand's unit-perspective view of concepts. This pioneering insight, he says, not only is an essential building block of her concept theory, but also welds together the three levels of logical theory and provides the clearest X-ray picture of our multilayered conceptual knowledge. Using the unit-perspective to expand Rand's theory of concepts, the author then devises a theory of (...) the proposition, giving considerable attention to axioms and statements about nonexistent subjects.

The Inexact and Separate Science of Economics represents the most ambitious attempt to provide a systematic account of economic methodology since the first edition of Blaug's The Methodology of Economics. As such, it has been the subject of extensive critical commentary. For all the attention it has received, however, some important aspects of the book's thesis have not been developed properly. Two important ones are what might be called, following the terminology used in the experimental economics literature, the ‘framing effect’ (...) of Hausman's definition of economics, and the significance of Hausman's claim that economists are committed to developing economics as a ‘separate’ science. To understand these points it is important to make explicit the position from which Hausman approaches the philosophy of science. (shrink)

The author endeavors to show how dialectical methods can reveal and clarify Ayn Rand’s philosophy from the two vital perspectives of the lives of individual human beings in relation to the world and in relation to other people and the social institutions under which they live. In so doing, he applies Chris Matthew Sciabarra’s Tri-Level Analysis model of social relations (derived from Rand’s social commentaries) and relates Rand’s metaphysical value-judgments to the cardinal values and virtues of her ethics.

The author provides another metaphysical argument to bolster his thesis of the logical harmony of determinism and volition. He shows how the typical mainstream and Objectivist doctrine of “libertarian” free will commits the same logical error as the Sophist attacks on the Law of Non-Contradiction—namely, an out-of-context interpretation of, respectively, the Law of Causality and the Law of Identity as being unconditional absolutes, which they are not and cannot be.

In these two volumes, a group of distinguished economists debate the way in which evidence, in particular econometric evidence, can and should be used to relate macroeconomic theories to the real world. Topics covered include the business cycle, monetary policy, economic growth, the impact of new econometric techniques, the IS-LM model, the labour market, new Keynesian macroeconomics, and the use of macroeconomics in official documents.

The author argues that Rand’s ethical theory is much closer in essence to the eudaimonist, self-perfectionist perspectives of Aristotle and the neo-Aristotelians, Douglas Den Uyl and Douglas Rasmussen, than to the “selfish,” egoistic ethics many assume to be her basic position. He discusses Rand’s anti-hedonist and pro-rational selfishness positions as corollaries of man’s life as the standard of moral value, as well as Rand’s point that treating either happiness or personal benefit as the standard of moral value is a reversal (...) of cause and effect. He also identifies the oppressive negativism in Rand’s discussion of the seven canonical Objectivist virtues. (shrink)

I argue in this paper that, like the Pyrrhonism of Sextus Empiricus, Wittgenstein’s response to negative–dogmatic skepticism in On Certainty turns on the attempt to free us from the demands of traditional philosophy and is therefore not a philosophical position, strictly speaking. Rather, it is a therapeutic metaphilosophy designed to bring into view (i.e., to illumine) the relationship between our everyday epistemic practices and those of philosophy such that we simultaneously come to recognize (a) what I call the pragmatic–transcendental self–standingness (...) of the everyday and (b) its philosophical–rational groundlessness. The Pyrrhonian illumination of the everyday is therapeutic in that it aims to purify our metadoxastic attitudes of dogmatism. (shrink)

The author explains that his previous philosophical arguments for compatibilism provide a robust basis for ethical and legal responsibility. He defends entity causation, arguing that no coherent model of the universe, including human action, can be formulated that rejects entities as the nexus of identity and causality. Finally, he contends, ontological compatibilism and ethical compatibilism are both best supported by a more fundamental methodological compatibilism of philosophical and scientific approaches to seeking truth.

ABSTRACT The author continues his challenge to the “official” Objectivist view of free will by addressing the implications of his value-determinism/conditional-volition model for various Objectivist moral concepts including value, sacrifice, virtue, obligation, and moral and legal responsibility and accountability. He argues that based on Rand’s definitions, the conventional understandings of sacrifice or betrayal of values, lapses in virtue, and breaches in morality need considerable reconceptualizing. The author gives special attention to Rand and Kant with regard to lying, use of force, (...) and acts of generosity, finding not nearly as much difference between them as is commonly believed.

This is an expanded, annotated bibliography of the work of the late Barbara Branden, who was Ayn Rand's first biographer, and who made many contributions to the early Objectivist literature.

The author reprises his review of The DIM Hypothesis by arguing for an expansion and revision of Leonard Peikoff's model to include not three, but four primary positions regarding integration : Integration, Disintegration, Abstract Misintegration, and Concrete Misintegration—and to include not just two mixtures of those primary positions, but twelve. He offers it as a work in progress and a remedy to the over-restrictiveness and resulting misrepresentations of various philosophers by Peikoff's version of the model.

In this third installment of his series on key, underappreciated ideas in Ayn Rand's epistemology, the author discusses the nature of differentiation and integration as the functional essence of consciousness and applies that insight to various cognitive and noncognitive processes of awareness, with a special emphasis on logic and illogic. He offers an extended analysis of the fallacies of “Frozen Abstraction” and “False Alternative,” as well as critiques of a long-standing Objectivist conflation of falsity and contradiction and a relatively more (...) recent Objectivist error, the fallacy of “genuine awareness.”.
