ROBERT L. CAMPBELL explains how Ayn Rand 's epistemology drew on ideas and findings from the Cognitive Revolution, the change in American psychology during the 1950' s that re-established mental processes as an object of study and overthrew behaviorism. Particularly noticeable is Rand 's reliance on George Miller's conclusions regarding limited cognitive capacity, and her broad agreement with Noam Chomsky's devastating critique of B. F. Skinner 's behaviorism. Both Rand 's points of contact-and differences-with the Cognitive Revolution are discussed. Once (...) the impact of the Cognitive Revolution on Rand is recognized, her insistence that philosophy owes nothing to psychology becomes harder to defend. (shrink)

Children are not simply molded by the environment; through constant inference and interpretation, they actively shape their own social world. This book is about that process. Elliot Turiel's work focuses on the development of moral judgment in children and adolescents and, more generally, on their evolving understanding of the conventions of social systems. His research suggests that social judgements are ordered, systematic, subtly discriminative, and related to behavior. His theory of the ways in which children generate social knowledge through their (...) social experiences will be of interest to a wide range of researchers and students in child development and education.

Thomas S. Kuhn's classic book is now available with a new index.

There has been much discussion recently about the scope and limits of purely symbolic models of the mind and about the proper role of connectionism in cognitive modeling. This paper describes the symbol grounding problem : How can the semantic interpretation of a formal symbol system be made intrinsic to the system, rather than just parasitic on the meanings in our heads? How can the meanings of the meaningless symbol tokens, manipulated solely on the basis of their shapes, be grounded (...) in anything but other meaningless symbols? The problem is analogous to trying to learn Chinese from a Chinese/Chinese dictionary alone. A candidate solution is sketched: Symbolic representations must be grounded bottom-up in nonsymbolic representations of two kinds: iconic representations, which are analogs of the proximal sensory projections of distal objects and events, and categorical representations, which are learned and innate feature-detectors that pick out the invariant features of object and event categories from their sensory projections. Elementary symbols are the names of these object and event categories, assigned on the basis of their categorical representations. Higher-order symbolic representations, grounded in these elementary symbols, consist of symbol strings describing category membership relations. Connectionism is one natural candidate for the mechanism that learns the invariant features underlying categorical representations, thereby connecting names to the proximal projections of the distal objects they stand for. In this way connectionism can be seen as a complementary component in a hybrid nonsymbolic/symbolic model of the mind, rather than a rival to purely symbolic modeling. Such a hybrid model would not have an autonomous symbolic module, however; the symbolic functions would emerge as an intrinsically dedicated symbol system as a consequence of the bottom-up grounding of categories ' names in their sensory representations. Symbol manipulation would be governed not just by the arbitrary shapes of the symbol tokens, but by the nonarbitrary shapes of the icons and category invariants in which they are grounded. (shrink)

In this highly original of realism, David Kelley argues that perception is the discrimination of objects as entities, that the awareness of these objects is direct, and that perception is a reliable foundation for empirical knowledge. His argument relies on the basic principle of the 'primacy of existence, ' in opposition to Cartesian representationalism and Kantian idealism.

THE 25TH ANNIVERSARY EDITION—The definitive statement of Ayn Rand’s philosophy as interpreted by her best student and chosen heir. This brilliantly conceived and organized book is Dr. Leonard Peikoff’s classic text on the abstract principles and practical applications of Objectivism, based on his lecture series “The Philosophy of Objectivism.” Ayn Rand said of these lectures: “Until or unless I write a comprehensive treatise on my philosophy, Dr. Peikoff’s course is the only authorized presentation of the entire theoretical structure of Objectivism—that (...) is, the only one that I know of my knowledge to be fully accurate.” In Objectivism, Peikoff covers every philosophic topic that Rand regarded as important—from certainty to money, from logic to art, from measurement to sex. Drawn from Rand’s published works as well as in-depth conversations between her and Peikoff, these chapters illuminate Objectivism—and its creator—with startling clarity. With Objectivism, the millions of readers who have been transformed by Atlas Shrugged and The Fountainhead will discover the full philosophical system underlying Ayn Rand’s work. (shrink)

The relationship between Rand and Branden changed over eighteen yaears from student and teacher, to friends, to colleagues, to lovers and finally antagonists.

Viable Values examines the most basic foundations of value and morality, demonstrating the shortcomings of major traditional views and proposing that morality is grounded in the objective requirements of human life. Smith argues that morality depends on a proper understanding of the concept of values, and that values depend on the alternative of life or death. She proposes that human beings need to be moral in order to live, explaining how life is the standard of morality, how flourishing is the (...) proper end and reward of living morally, and how an intelligent egoism is the path to flourishing.

This article focuses on the problem of representational content. Accounting for representational content is the central issue in contemporary naturalism: it is the major remaining task facing a naturalistic conception of the world. Representational content is also the central barrier to contemporary cognitive science and artificial intelligence: it is not possible to understand representation in animals nor to construct machines with genuine representation given current (lack of) understanding of what representation is. An elaborated critique is offered to current approaches to (...) representation, arguing that the basic underlying approach is, at root, logically incoherent, and, thus, that standard approaches are doomed to failure. An alternative model of representation - interactivism - is presented that avoids or solves the problems facing standard approaches. Interactivism is framed by a version of functionalism, and a naturalization of that functionalism completes an outline of a naturalization of representation and representational content. (shrink)

This is not your psychoanalyst's unconscious.

Ayn Rand is well known for advocating egoism, but the substance of that instruction is rarely understood. Far from representing the rejection of morality, selfishness, in Rand's view, actually demands the practice of a systematic code of ethics. This book explains the fundamental virtues that Rand considers vital for a person to achieve his objective well-being: rationality, honesty, independence, justice, integrity, productiveness, and pride. Tracing Rand's account of the harmony of human beings' rational interests, Smith examines what each of these (...) virtues consists of, why it is a virtue, and what it demands of a person in practice. Along the way she addresses the status of several conventional virtues within Rand's theory, considering traits such as kindness, charity, generosity, temperance, courage, forgiveness, and humility. Ayn Rand's Normative Ethics thus offers an in-depth exploration of several specific virtues and an illuminating integration of these with the broader theory of egoism. (shrink)

Many of our questions about religion, says renowned anthropologist Pascal Boyer, are no longer mysteries. We are beginning to know how to answer questions such as "Why do people have religion?" Using findings from anthropology, cognitive science, linguistics, and evolutionary biology, Religion Explained shows how this aspect of human consciousness is increasingly admissible to coherent, naturalistic explanation. This brilliant and controversial book gives readers the first scientific explanation for what religious feeling is really about, what it consists of, and where (...) it comes from. (shrink)

The bestselling biography of one of the 20th century's most remarkable and controversial writers. Author Barbara Branden, who knew Rand for nineteen years, provides a matchless portrait of this fiercely private and complex woman.

Objectivists insist on the primacy of existence—the axiom that existence exists. This axiom is taken to entail that the universe exists independent of any consciousness, human or divine. Objectivists hold that a straightforward consequence of this axiom is that God does not exist. The central argument of this paper is that the Objectivist atheological argument based on the primacy of existence fails. Atheological arguments based on the alleged incoherence of the Divine attributes are at best inconclusive. Theism has not been (...) shown to be incompatible with Objectivism. (shrink)

Admirers of Isabel Paterson's political and historical theory have often been critical of her use of imagery drawn from various branches of engineering. An examination of Ayn Rand's comments on this issue introduces important questions about the use of imagistic language in theory and description, the role of imagery in Paterson's theories, and the difficulties that Rand encountered in assessing those theories.

Identifies the roots of Nazism in the philosophical ideas of the worship of unreason, demand for self-sacrifice, and elevation of society over the individual, and argues that these ideas are present in America today.

Objectivism is committed to atheism. However, Objectivists have done little work in Philosophy of Religion. This article argues that much of the work that they have done is fallacious. In particular, the critique of God that Peikoff gives in Objectivism: The Philosophy of Ayn Rand is deeply flawed. If they want to justify their atheism, Objectivists need to rework and revise their arguments; in the final analysis, however, it is doubtful that their efforts will succeed.
