Darwinian Evolution and Classical Liberalism brings together a collection of new essays that examine the multifaceted ferment between Darwinian biology and classical liberalism.
In his State of the Union address on January 31, 2006, President George W. Bush asserted: “for all Americans, we must confront the rising cost of care, strengthen the doctor-patient relationship, and help people afford the insurance coverage they need.” Soon thereafter, the White House National Economic Council released a summary of President Bush's plans for health care reform. The Bush plan argues that increased consumer control over health care purchasing decisions will go a long way to solving America's (...) health care woes. By making patients more value-conscious consumers, the Bush Administration hopes to reduce costs, improve quality and increase competition within the health care sector.The problem of rising health care costs is not new. In fact, President Bush's statement could have come from any American President in the last fifty years. (shrink)
I have taken an experimental approach to this question. Freely voluntary acts are preceded by a specific electrical change in the brain that begins 550 ms before the act. Human subjects became aware of intention to act 350-400 ms after RP starts, but 200 ms. before the motor act. The volitional process is therefore initiated unconsciously. But the conscious function could still control the outcome; it can veto the act. Free will is therefore not excluded. These findings put constraints on (...) views of how free will may operate; it would not initiate a voluntary act but it could control performance of the act. The findings also affect views of guilt and responsibility. But the deeper question still remains: Are freely voluntary acts subject to macro-deterministic laws or can they appear without such constraints, non-determined by natural laws and ‘truly free'? I shall present an experimentalist view about these fundamental philosophical opposites. (shrink)

This paper offers an analysis of the nature of epistemic trust. With increased philosophical attention to social epistemology in general and testimony in particular, the role for an epistemic or intellectual version of trust has loomed large in recent debates. But, too often, epistemologists talk about trust without really providing a sustained examination of the concept. After some introductory comments, I begin by addressing various components key to trust simpliciter. In particular, I examine what we might think of when we (...) consider what it means to place trust in someone. Once we have examined trust in general, we can modify this discussion to derive an epistemic version of trust—placing trust in someone for an epistemic reason. I argue that ET includes four components: belief, communication, reliance, and confidence. The first two sets are distinctively epistemic and the second set of conditions form the core of any kind of trust. Put together,.. (shrink)

The chief goal of Velmans' article is to find a way to solve the problem of how conscious experience could have bodily effects. I shall discuss his treatment of this below. First, I would like to deal with Velmans' treatment of my own studies of volition and free will in relation to brain processes. Unconscious Initiation and Conscious Veto of Freely Voluntary Acts Velmans appropriately refers to our experimental study that found that onset of an electrically observable cerebral process preceded (...) the appearance of the subject's awareness of the conscious wish to act, by at least 350 msec. That indicated that the volitional process is initiated unconsciously. Velmans uses the term preconscious instead of unconscious. But, in fact, subjects have no reportable awareness or intuitive feeling that the brain has started a process before their conscious wish/urge to act appears. Unconscious initiation of the voluntary process appeared to mean that conscious free will could not actually 'tell' the brain to begin its preparation to carry out a voluntary act. (shrink)

The paper begins by contrasting the unitary nature of conscious experience with the demonstrable localization of neural events. Philosophers and neuroscientists have developed models to account for this paradox, but they have yet to be tested empirically. The author proposes a `Conscious Mental Field', which is produced by, but is phenomenologically distinct from, brain activity. The hypothesis is, in principle, open to experimental verification. The paper suggests appropriate surgical procedures and some of the difficulties that would need to be overcome (...) in such an experiment. (shrink)
Ichikawa and Jarvis offer a new rationalist theory of mental content and defend a traditional epistemology of philosophy. They argue that philosophical inquiry is continuous with non-philosophical inquiry, and can be genuinely a priori, and that intuitions do not play an important role in mental content or the a priori.
Commentary on John Searle's Article John Searle presents a philosopher's view of how conscious experience and free action relate to brain function. That view demands an examination by a neuroscientist who has experimentally investigated this issue.
This paper begins with the oft-repeated claim that having faith involves trust in God. Taking this platitude seriously requires at least two philosophical tasks. First, one must address the relevant notion of “trust” guiding the platitude. I offer a sketch of epistemic trust: arguing that epistemic trust involves several components: acceptance, communication, dependence, and confidence. The first duo concerns the epistemic element of epistemic trust and the second part delimit the fiducial aspect to epistemic trust. Second, one must also examine (...) what differentiates faith qua trust. I argue that we should not distinguish faith from trust merely by believing religious propositions but by the attitudes they express. In particular, the attitude of faith is more deeply entrenched and central to one’s noetic structure than trust simpliciter. The paper ends by arguing that the account proposed insofar as it accommodates and explains certain “faith desiderata”. We can thus give content to the “faith is a kind of trust” platitude with a model of trust on hand while showing how that model confirms and explains important features of faith. (shrink)
Sensation elicited by a skin stimulus was subjectively reported to feel stronger when followed by a stimulus to somatosensory cerebral cortex , even when C was delayed by up to 400 ms or more. This expands the potentiality for retroactive effects beyond that previously known as backward masking. It also demonstrates that the content of a sensory experience can be altered by another cerebral input introduced after the sensory signal arrives at the cortex. The long effective S-C intervals support the (...) thesis that a duration of cortical activity of up to 0.5 s is required before awareness of a sensory stimulus is developed. (shrink)
One of the deepest ideological divides in contemporary epistemology concerns the relative importance of belief versus credence. A prominent consideration in favor of credence-based epistemology is the ease with which it appears to account for rational action. In contrast, cases with risky payoff structures threaten to break the link between rational belief and rational action. This threat poses a challenge to traditional epistemology, which maintains the theoretical prominence of belief. The core problem, we suggest, is that belief may not be (...) enough to register all aspects of a subject’s epistemic position with respect to any given proposition. We claim this problem can be solved by introducing other doxastic attitudes—genuine representations—that differ in strength from belief. The resulting alternative picture, a kind of doxastic states pluralism, retains the central features of traditional epistemology—most saliently, an emphasis on truth as a kind of objective accuracy—while adequately accounting for rational action.

According to robust virtue epistemology , knowledge is type-identical with a particular species of cognitive achievement. The identification itself is subject to some criticism on the grounds that it fails to account for the anti-luck features of knowledge. Although critics have largely focused on environmental luck, the fundamental philosophical problem facing RVE is that it is not clear why it should be a distinctive feature of cognitive abilities that they ordinarily produce beliefs in a way that is safe. We propose (...) a novel way to resolve this problem. Key to our proposal will be an appreciation of different representational states beholden to truth. We suggest these different representational states are distinguished by how, in the proper governance of these states, the twin goods of attaining truth and avoiding error are weighted. Moreover, we explain how varieties of representational states line up with varieties of cognitive achievement such that knowledge, cum cognitive achievement, must be safe because of the kind of attempt at success that belief is—namely, an attempt that places the premium it does on avoiding error.

The problem of free will lies at the heart of modern scientific studies of consciousness. An influential series of experiments by Libet has suggested that conscious intentions arise as a result of brain activity. This contrasts with traditional concepts of free will, in which the mind controls the body. A more recent study by Haggard and Eimer has further examined the relation between intention and brain processes, concluding that conscious awareness of intention is linked to the choice or selection of (...) a specific action, and not to the earliest initiation of action processes. The exchange of views in this paper further explores the relation between conscious intention and brain activity. (shrink)
Solutions to the ‘hard problem’ of consciousness must accept conscious experience as a fundamental non-reducible phenomenon in nature, as Chalmers suggests. Chalmers proposes candidates for an acceptable theory, but I find basic flaws in these. Our own experimental investigations of brain processes causally involved in the development of conscious experience appear to meet Chalmers’ requirement. Even more directly, I had previously proposed a hypothetical ‘conscious mental field’ as an emergent property of appropriate neural activities, with the attributes of integrated subjective (...) experience and a causal ability to modulate some neural processes. This theory meets all the requirements imposed by the ‘hard problem’ and, significantly, it is experimentally testable. (shrink)
Cowardice asks the question, is it safe? Expediency asks the question, is it politic? Vanity asks the question, is it popular? But conscience asks the question, is it right? And there comes a time when one must take a position that is neither safe, nor politic, nor popular, but he must take it because conscience tells him it is right.Your burden is not to clear your conscience but to learn how to bear the burdens on your conscience.Since the time of (...) hippocrates, Western medicine has assumed that the exercise of conscience is fundamental to its sound practice. Despite significant changes to medical training in the intervening millennia, this emphasis on conscience remains. "The Physician's Pledge" of the World... (shrink)
In several of our articles we have drawn analogies between inattentional blindness paradigms and misdirection. Memmert however, has criticized this analogy and urged for caution in assuming too much of a close relationship between these two phenomena. Here we consider the points raised by Memmert and highlight some misunderstandings and omissions in his interpretation of our work, which substantially undermine his argument. Debating the similarities and differences between aspects of misdirection and inattentional blindness is valuable and has the potential to (...) highlight the utility of these two phenomena. However, it is important not to be misdirected by subtle differences between particular instances of each phenomenon, at the expense of failing to detect the opportunities that these phenomena present for extending our understanding of attention and awareness.

Our aim is to discover whether the notion of algorithmic orbit-complexity can serve to define “chaos” in a dynamical system. We begin with a mostly expository discussion of algorithmic complexity and certain results of Brudno, Pesin, and Ruelle (BRP theorems) which relate the degree of exponential instability of a dynamical system to the average algorithmic complexity of its orbits. When one speaks of predicting the behavior of a dynamical system, one usually has in mind one or more variables in the (...) phase space that are of particular interest. To say that the system is unpredictable is, roughly, to say that one cannot feasibly determine future values of these variables from an approximation of the initial conditions of the system. We introduce the notions of restrictedexponential instability and conditionalorbit-complexity, and announce a new and rather general result, similar in spirit to the BRP theorems, establishing average conditional orbit-complexity as a lower bound for the degree of restricted exponential instability in a dynamical system. The BRP theorems require the phase space to be compact and metrizable. We construct a noncompact kicked rotor dynamical system of physical interest, and show that the relationship between orbit-complexity and exponential instability fails to hold for this system. We conclude that orbit-complexity cannot serve as a general definition of “chaos.”. (shrink)
The Problem of Evil: New Philosophical Directions brings together a diversity of philosophical views, methods, and approaches to the much-discussed topic of evil and its bearing on religious belief. Through both general and specific examinations of the problem of evil, this book proposes new directions for philosophical thought.
O'Regan & Noë (O&N) present the most radical departure yet from traditional approaches to visual perception. However, internal representation cannot yet be abandoned. I will discuss: (1) recent evidence for very short-term pictorial representation of each fixation; (2) the possibility of abstract representation, largely unconsidered by the authors; and (3) that sensorimotor contingency theory requires internal visual retention and comparison.
Let me begin with what I take to be the two most significant features of this collection. First, it addresses an area that is woefully under-discussed: the intersection of virtue epistemology and philosophy of religion. Each is a massively influential and important field in its own right, so bringing the two into dialogue makes tremendous sense. This collection accomplishes much in this regard but also underscores the amount of work that needs to be developed. Bringing together virtue epistemology, philosophy of (...) religion, testimony, analyses of trust/faith, disagreement, etc. makes the volume of interest to philosophers working in a wide variety of fields. Second, each contributor is an extremely capable philosopher on the cutting edge of his/her field. The list is a murderer’s row of epistemologists and philosophers of religion, and their contributions will accordingly provide fodder for continued work regarding all of the topics discussed.W. Jay Wood begins with the necessity of fait .. (shrink)
This collection brings together new papers addressing the philosophical challenges that the concept of a Devil presents, bringing philosophical rigor to treatments of the Devil. Contributors approach the idea of the Devil from a variety of philosophical traditions, methodologies, and styles, providing a comprehensive philosophical overview that contemplates the existence, nature, and purpose of the Devil. While some papers take a classical approach to the Devil, drawing on biblical exegesis, other contributors approach the topic of the Devil from epistemological, metaphysical, (...) phenomenological, and ethical perspectives. This volume will be relevant to researchers and scholars interested in philosophical conceptions of the Devil and related areas, such as philosophers of religion, theologians, and scholars working in philosophical theology and demonology.
