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.

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 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.

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.”.

The author examines the canonical Objectivist model of free will and finds it wanting, amounting to a form of Agency—Indeterminism. Employing an Aristotelian Four Cause analysis, he explores the complementary roles of determinism and free will, as well as the conditional nature of necessity and contingency, in understanding how causality operates in the human realm. He proposes an integration of what he calls “value-determinism” and “conditional free will,” arguing that it amounts to a basic axiom of human choice and action, (...) and urges its acceptance in place of the Orthodox Objectivist view of free will.

William Dwyer reviews Initiative: Human Agency and Society, in which Tibor Machan argues that free will is a prerequisite for knowledge, ethics, and political liberty. Machan criticizes Hayek, Stigler, and "public choice" economics for their economic determinism and for discounting the importance of abstract ideas. Despite making a good case against environmental and economic determinism, Machan fails adequately to defend his central thesis that free will exists and that it is required for normative values.

In this sequel to his essay "Ayn Rand and The Objective'" (JARS, Fall 2007), the author warns against "the seduction of 'the basic"' and uses ideas by Efron, Peikoff, and Aristotle to argue that introspection and mental data (including mind) are objective and that causal efficacy of mind and mind-body interaction only make sense if mind is conceived of not as an attribute, but as an entity (viz., the conscious human brain). None of this, however, implies Epiphenomenalism or that consciousness (...) is irrelevant to human history. (shrink)
