Paul M. Churchland on Commonsense and Cognition

Go

You came to this book assuming that the basic units of human cognition are states such as thoughts, beliefs, perceptions, desires, and preferences. That assumption is natural enough: it is built into the vocabulary of every natural language. And each state is typically identified by way of a specific sentence in one’s natural language: one has the belief that P, or the desire that Q, for example, where P and Q are sentences. Human cognition is thus commonsensically portrayed as a dance of sentential or propositional states, with the basic unit of computation being the inference from several such states to some further sentential state. ¶ These assumptions are central elements in our standard conception of human cognitive activity, a conception often called “folk psychology” to acknowledge it as the common property of folks generally. Their universality notwithstanding, these bedrock assumptions are probably mistaken.

Paul M. Churchland on Introspection

But who, in that case, can be watching this pixilated show? The answer is straightforward: no one. There is no distinct "self" in there, beyond the brain as a whole. On the other hand, almost every part of the brain is being "watched" by some other part of the brain, often by several other parts at once.

Matthew C. Bagger on Preferring Naturalistic Explanations

Go

We can never assert that, in principle, an event resists naturalistic explanation. A perfectly substantiated, anomalous event, rather than providing evidence for the supernatural, merely calls into question our understanding of particular natural laws. In the modern era, this position fairly accurately represents the educated response to novelty. Rather than invoke the supernatural, we can always adjust our knowledge of the natural in extreme cases. In the modern age in actual inquiry, we never reach the point where we throw up our hands and appeal to divine intervention to explain a localized event like an extraordinary experience.

The Darwinian Revolution

Go

Originally published in 1979, The Darwinian Revolution was the first comprehensive and readable synthesis of the history of evolutionary thought. Though the years since have seen an enormous flowering of research on Darwin and other nineteenth-century scientists concerned with evolution, as well as the larger social and cultural responses to their work, The Darwinian Revolution remains remarkably current and stimulating. For this edition Michael Ruse has written a new afterword that takes into account the research published since his book’s first appearance. "It is difficult to believe that yet another book on Darwin and the Darwinian Revolution could add anything new or contain any surprises. Ruse’s book is an exception on all counts. Darwin scholars and the general reader alike can learn from it." ~ David L. Hull, Nature

Rethinking Intuition

Go

Ancients and moderns alike have constructed arguments and assessed theories on the basis of common sense and intuitive judgments. Yet, despite the important role intuitions play in philosophy, there has been little reflection on fundamental questions concerning the sort of data intuitions provide, how they are supposed to lead us to the truth, and why we should treat them as important. In addition, recent psychological research seems to pose serious challenges to traditional intuition-driven philosophical inquiry. Rethinking Intuition brings together a distinguished group of philosophers and psychologists to discuss these important issues. Students and scholars in both fields will find this book to be of great value. ~ Book Description

Does the Many-Universes Hypothesis Really Explain the Fine-Tuning?

Go

The last thirty years have witnessed a major revival in the philosophical, theological, scientific, and popular literature of the traditional design argument for theism. Probably the most convincing and widely discussed of these arguments is based on the so-called “fine-tuning” of the cosmos, which refers the fact that the parameters of physics and the initial conditions of the universe are balanced on a razor’s edge for life to occur. For example, calculations by Brandon Carter indicate that if the force of gravity had been stronger or weaker by one part in 1040, then life-sustaining stars could not exist (Davies, 1984, p. 242); similarly, calculations indicate that if the strong nuclear force, the force that binds protons and neutrons together in an atom, had been stronger or weaker by as little as 5%, life would be impossible. ( Barrow and Tipler, p. 322.) As the eminent Princeton physicist Freeman Dyson notes, “There are many . . . lucky accidents in physics. Without such accidents, water could not exist as liquid, chains of carbon atoms could not form complex organic molecules, and hydrogen atoms could not form breakable bridges between molecules” (1979, p. 251) — in short, life as we know it would be impossible.

Academic Integration and the Christian Scholar

Go

Thoughtful Christians are agreed that an important component of Christian scholarship is the integration of faith and learning, as it is sometimes called. Because Christians are interested in the truth for its own sake and because they are called to proclaim and defend their views to an unbelieving world and to seek to live consistently with those views, it is important for members of the believing community to think carefully about how to integrate their carefully formed theological beliefs with prominent claims in other fields of study. As St. Augustine wisely asserted, "We must show our Scriptures not to be in conflict with whatever [our critics] can demonstrate about the nature of things from reliable sources."1 However, the task of integration is hard work and there is no widespread agreement about how it is to be done generally or about what its results should look like in specific cases. In what follows, I shall do three things to contribute to the integrative enterprise: 1) describe the relation between integration and spiritual formation; 2) discuss current integrative priorities for the Christian scholar; 3) analyze the epistemic tasks for and models employed in integration.

The Fine-Tuning Design Argument

Go

Suppose we went on a mission to Mars, and found a domed structure in which everything was set up just right for life to exist. The temperature, for example, was set around 70o F and the humidity was at 50%; moreover, there was an oxygen recycling system, an energy gathering system, and a whole system for the production of food. Put simply, the domed structure appeared to be a fully functioning biosphere. What conclusion would we draw from finding this structure? Would we draw the conclusion that it just happened to form by chance? Certainly not. Instead, we would unanimously conclude that it was designed by some intelligent being. Why would we draw this conclusion? Because an intelligent designer appears to be the only plausible explanation for the existence of the structure. That is, the only alternative explanation we can think of — that the structure was formed by some natural process — seems extremely unlikely. Of course, it is possible that, for example, through some volcanic eruption various metals and other compounds could have formed, and then separated out in just the right way to produce the “biosphere,” but such a scenario strikes us as extraordinarily unlikely, thus making this alternative explanation unbelievable.

The Incompatibility of Naturalism  and Scientific Realism

Go

Whenever philosophers bother to offer a defense for philosophical naturalism, they typically appeal to the authority of natural science. Science is supposed to provide us with a picture of the world so much more reliable and well-supported than that provided by any non-scientific source of information that we are entitled, perhaps even obliged, to withhold belief in anything that is not an intrinsic part of our our best scientific picture of the world. This scientism is taken to support philosophical naturalism, since, at present, our best scientific picture of the world is an essentially materialistic one, with no reference to causal agencies other than those that can be located within space and time. This defense of naturalism presupposes a version of scientific realism: unless science provides us with objective truth about reality, it has no authority to dictate to us the form which our philosophical ontology and metaphysics must take. Science construed as a mere instrument for manipulating experience, or merely as an autonomous construction of our society, without reference to our reality, tells us nothing about what kinds of things really exist and act. In this essay, I will argue, somewhat paradoxically, that scientific realism can provide no support to philosophical naturalism. In fact, the situation is precisely the reverse: naturalism and scientific realism are incompatible.

The Enemy Within
