Compiles the essays of Descartes, the seventeenth-century philosopher who rejected Greek and medieval scholasticism.

Robert Kane provides a critical overview of debates about free will of the past half century, relating this recent inquiry to the broader history of the free will issue and to vital currents of twentieth century thought. Kane also defends a traditional libertarian or incompatibilist view of free will, employing arguments that are both new to philosophy and that respond to contemporary developments in physics and biology, neuro science, and the cognitive and behavioral sciences.

The relation between subjective consciousness and the physical brain is widely regarded as the last mystery facing science. David Papineau argues that there is no real puzzle here. Consciousness seems mysterious, not because of any hidden essence, but only because we think about it in a special way. Papineau exposes the confusion, and dispels the mystery: we see consciousness in its place in the material world, and we are on the way to a proper understanding of the mind.

This text presents three recently discovered public lectures from the 60s in which Feynman addresses a non-scientific audience. Feynman attempts to engage an audience with the questions that most inspired and troubled him. Beginning by asking what is the value of science, Feynman goes on to address various related questions: can scientific views be reconciled with religious beliefs? Why in this supposedly scientific age is there such widespread fascination with flying saucers, astrology and martian invasions? How does the media betray (...) the public? What is the value of doubt? (shrink)

My dissertation consists of two main parts. In the first part, I begin by assuming the plausibility of the libertarian thesis that agents sometimes could have done otherwise than they did given the very same history of the world. In light of this assumption, I undertake to develop a model of agency which does not employ the concept of agent-causation. My agency theory is developed in three main stages: I suggest that any agency theory must satisfy four desiderata: It must (...) adequately account for the freedom and responsibility of human agents. It must provide an adequate answer to the question of what distinguishes human actions from mere happenings. It must adequately account for the epistemological fact that human agents have an immediate and nonobservational awareness of their actions. It should have the support of a respectable philosophical tradition. I argue that agent-causation provides a theory of agency which fails adequately to satisfy these four desiderata. I claim both that human actions are uncaused exercisings by agents of their powers and that human agents typically act for reasons. I maintain that the central issue dividing agency theorists and nonagency theorists is whether reasons for performing actions cause the latter. I maintain that the sense of 'because' in 'I did x because...' is not causal in nature, but teleological. ;Having developed my model of agency, in the second part of my dissertation I investigate what are some of the paradigmatic actions human agents perform. I claim that bodily actions, such as moving an arm, are psychological in nature. Essential to my argument is the concept of a body-image. A normal agent 'feels' as if she is present in her physical arm. The way a normal agent feels is revealed in the case of a phantom limb. The subject of a phantom arm feels as if her amputated physical arm is still there and she can move while feeling armishly. I maintain that the bodily action of moving an arm is the agent's movement as a psychological arm-image of her physical arm, whether the physical arm is present or not. (shrink)

First, The doctrine of naturalism, That reality is spatio-Temporal, Is defended. Second, The doctrine of materialism or physicalism, That this spatio-Temporal reality involves nothing but the entities of physics working according to the principles of physics, Is defended. Third, It is argued that these doctrines do not constitute a "first philosophy." a satisfactory first philosophy should recognize universals, In the form of instantiated properties and relations. Laws of nature are constituted by relations between universals. What universals there are, And what (...) relations hold between them, Must be discovered "a posteriori" by scientific investigation.

The present article examines how people’s belief in an afterlife, as well as closely related supernatural beliefs, may open an empirical backdoor to our understanding of the evolution of human social cognition. Recent findings and logic from the cognitive sciences contribute to a novel theory of existential psychology, one that is grounded in the tenets of Darwinian natural selection. Many of the predominant questions of existential psychology strike at the heart of cognitive science. They involve: causal attribution (why is mortal (...) behavior represented as being causally related to one’s afterlife? how are dead agents envisaged as communicating messages to the living?), moral judgment (why are certain social behaviors, i.e., transgressions, believed to have ultimate repercussions after death or to reap the punishment of disgruntled ancestors?), theory of mind (how can we know what it is “like” to be dead? what social-cognitive strategies do people use to reason about the minds of the dead?), concept acquisition (how does a common-sense dualism interact with a formalized socio-religious indoctrination in childhood? how are supernatural properties of the dead conceptualized by young minds?), and teleological reasoning (why do people so often see their lives as being designed for a purpose that must be accomplished before they perish? how do various life events affect people’s interpretation of this purpose?), among others. The central thesis of the present article is that an organized cognitive “system” dedicated to forming illusory representations of (1) psychological immortality, (2) the intelligent design of the self, and (3) the symbolic meaning of natural events evolved in response to the unique selective pressures of the human social environment.

How is consciousness possible? What biological purpose does it serve? And why do we value it so highly? In Soul Dust, the psychologist Nicholas Humphrey, a leading figure in consciousness research, proposes a startling new theory. Consciousness, he argues, is nothing less than a magical-mystery show that we stage for ourselves inside our own heads. This self-made show lights up the world for us and makes us feel special and transcendent. Thus consciousness paves the way for spirituality, and allows us, (...) as human beings, to reap the rewards, and anxieties, of living in what Humphrey calls the "soul niche." Tightly argued, intellectually gripping, and a joy to read, Soul Dust provides answers to the deepest questions. It shows how the problem of consciousness merges with questions that obsess us all--how life should be lived and the fear of death. Resting firmly on neuroscience and evolutionary theory, and drawing a wealth of insights from philosophy and literature, Soul Dust is an uncompromising yet life-affirming work--one that never loses sight of the majesty and wonder of consciousness.
