Michael Dummett's three John Dewey Lectures--"The Concept of Truth," "Statements About the Past," and "The Metaphysics of Time"--were delivered at Columbia University in the spring of 2002. Revised and expanded, the lectures are presented here along with two new essays by Dummett, "Truth: Deniers and Defenders" and "The Indispensability of the Concept of Truth." In _Truth and the Past,_ Dummett clarifies his current positions on the metaphysical issue of realism and the philosophy of language. He is best known as a (...) proponent of antirealism, which loosely characterizes truth as what we are capable of knowing. The events of the past and statements about them are critical tests of an antirealist position. These essays continue and significantly contribute to Dummett's work. (shrink)

What do we see? We are visually conscious of colors and shapes, but are we also visually conscious of complex properties such as being John Malkovich? In this book, Susanna Siegel develops a framework for understanding the contents of visual experience, and argues that these contents involve all sorts of complex properties. Siegel starts by analyzing the notion of the contents of experience, and by arguing that theorists of all stripes should accept that experiences have contents. She then introduces a (...) method for discovering the contents of experience: the method of phenomenal contrast. This method relies only minimally on introspection, and allows rigorous support for claims about experience. She then applies the method to make the case that we are conscious of many kinds of properties, of all sorts of causal properties, and of many other complex properties. She goes on to use the method to help analyze difficult questions about our consciousness of objects and their role in the contents of experience, and to reconceptualize the distinction between perception and sensation. Siegel's results are important for many areas of philosophy, including the philosophy of mind, epistemology, and the philosophy of science. They are also important for the psychology and cognitive neuroscience of vision. (shrink)

I develop a nontheistic (quasi-)Berkeleyan idealism. The basic strategy is to peel away the attributes of God that aren't essential for role he plays in idealist metaphysics. God's omnibenevolence, his desires, intentions, beliefs, his very status as an agent ... aren't relevant to the work he does. When we peel all these things away, we're left with a view on which reality is a vast unity of consciousness, weaving together sensory experiences of colors, shapes, sounds, sizes, etc. into the trees, (...) electrons, black holes, and central nervous systems that fill the world around us. This phenomenal unity is governed by laws analogous to those posited by materialists, governing the unfolding of reality. I argue that if reality is fundamentally phenomenal in this way, we can give a unique account of perception that robustly captures direct realist intuitions of reality forming the "constituents" of our experiences: In perception, our finite unities of consciousness come to literally overlap with the unity of consciousness that is reality. I assess the unique virtues and challenges such a view faces, paying particular attention to the question of whether idealism entails a profligacy of physical laws. (shrink)

How does the modern scientific conception of time constrain the project of assigning the mind its proper place in nature? On the scientific conception, it makes no sense to speak of the duration of a pain, or the simultaneity of sensations occurring in different parts of the brain. Such considerations led Henri Poincaré, one of the founders of the modern conception, to conclude that consciousness does not exist in spacetime, but serves as the basic material out of which we must (...) create the physical world. The central claim of Sensorama is that Poincaré was substantially correct. The best way to reconcile the scientific conception of time with the evidence of introspection is through a phenomenalist metaphysic according to which consciousness exists in neither time nor space, but serves as a basis for the logical construction of spacetime and its contents.

The Matrix presents a version of an old philosophical fable: the brain in a vat. A disembodied brain is floating in a vat, inside a scientist’s laboratory. The scientist has arranged that the brain will be stimulated with the same sort of inputs that a normal embodied brain receives. To do this, the brain is connected to a giant computer simulation of a world. The simulation determines which inputs the brain receives. When the brain produces outputs, these are fed back (...) into the simulation. The internal state of the brain is just like that of a normal brain, despite the fact that it lacks a body. From the brain’s point of view, things seem very much as they seem to you and me. (shrink)

Hilary Putnam deals in this book with some of the most fundamental persistent problems in philosophy: the nature of truth, knowledge and rationality. His aim is to break down the fixed categories of thought which have always appeared to define and constrain the permissible solutions to these problems.

This book is the one to put into the hands of those who have been over-impressed by Austin 's critics....[Warnock's] brilliant editing puts everybody who is concerned with philosophical problems in his debt.

ABSTRACT According to edenic idealism, our ordinary object terms refer to items in the manifest world—the world of primitive objects and properties presented in experience. I motivate edenic idealism as a response to scenarios where it is difficult to match the objects in experience with corresponding items in the external world. I argue that edenic idealism has important semantic advantages over realism: it is the most intuitive view of what we are actually talking about when we use terms for objects.

According to phenomenalism, physical things are a certain kind of possibility for experience. This paper clarifies the phenomenalist position and addresses some main objections to it, with the aim of showing that phenomenalism is a live option that merits a place alongside dualism and materialism in contemporary metaphysical debate.

A World for Us aims to refute physical realism and establish in its place a form of idealism. Physical realism, in the sense in which John Foster understands it, takes the physical world to be something whose existence is both logically independent of the human mind and metaphysically fundamental. Foster identifies a number of problems for this realist view, but his main objection is that it does not accord the world the requisite empirical immanence. The form of idealism that he (...) tries to establish in its place rejects the realist view in both its aspects. It takes the world to be something whose existence is ultimately constituted by facts about human sensory experience, or by some richer complex of non-physical facts in which such experiential facts centrally feature. Foster calls this phenomenalistic idealism. He tries to establish a specific version of such phenomenalistic idealism, in which the experiential facts that centrally feature in the constitutive creation of the world are ones that concern the organization of human sensory experience. The basic idea of this version is that, in the context of certain other constitutively relevant factors, this sensory organization creates the physical world by disposing things to appear systematically world-wise at the human empirical viewpoint. Chief among these other relevant factors is the role of God as the one who is responsible for the sensory organization and ordains the system of appearance it yields. It is this that gives the idealistically created world its objectivity and allows it to qualify as a real world. (shrink)

According to Russell, the intrinsic nature of the physical is the same as or deeply analogous to phenomenal qualities, those properties known through acquaintance in one's subjective experience. I defend his position and argue that it implies a kind of idealism, specifically the view that any intrinsic physical property instance can only exist as an object of acquaintance. This follows because a necessary feature of physicality is spatial location, and hence the intrinsic nature of the physical must share with phenomenal (...) qualities whatever makes some of them suitable space occupants. That feature is their occupying phenomenal spaces. There are reasons for believing that it is conceptually impossible for there to be a phenomenal space without a subject acquainted with its contents. Therefore, intrinsic physical properties must be objects of acquaintance. This view is shown to be compatible with contemporary science, and a scientific idealist metaphysic is briefly sketched.

This chapter argues, using the method of phenomenal contrast, that causation is represented in visual experience. The conclusion is contrasted with the conclusions drawn by Michotte in his book The Perception of Causation.
