Mark Johnson is one of the great thinkers of our time on how the body shapes the mind. This book brings together a selection of essays from the past two decades that build a powerful argument that any scientifically and philosophically satisfactory view of mind and thought must ultimately explain how bodily perception and action give rise to cognition, meaning, language, action, and values. A brief account of Johnson’s own intellectual journey, through which we track some of the most important discoveries in the field over the past forty years, sets the stage. Subsequent chapters set out Johnson’s important role in embodied cognition theory, including his cofounding of conceptual metaphor theory and, later, their theory of bodily structures and processes that underlie all meaning, conceptualization, and reasoning. A detailed account of how meaning arises from our physical engagement with our environments provides the basis for a nondualistic, nonreductive view of mind that he sees as most congruous with the latest cognitive science. A concluding section explores the implications of our embodiment for our understanding of knowledge, reason, and truth. The resulting book will be essential for all philosophers dealing with mind, thought, and language.

This chapter distinguishes the clusters of psychologically real heuristics that govern our use of terms—the “psi-concepts”—from the “phi-concepts” or meanings that are the semantic determinants of the extensions of the terms in question, and hence of the truth-conditions of the sentences that contain those terms. Concerning the psi-concepts the chapter proposes a new, empirically motivated, and philosophically consequential amendment to both the theory-theory and the prototype theory, namely the generic encoding hypothesis: the heuristics which typically guide our use of terms by exploiting prevalence, cue-validity, and causal explanatory structure are properly formulated in generic terms. The chapter then explores the philosophical consequences of the generic encoding hypothesis, exploring its destructive impact on the method of cases (with particular attention to its use in the philosophy of personal identity), philosophical analysis, the “normativity of meaning,” and the idea that we know how to use terms by grasping meanings.

Barry Stroud’s The Quest for Reality is a fine book that requires and repays several re-readings. Among the book’s many virtues is its appropriate skepticism towards the metaphysical ambition to treat some basic physical science as a fundamental ontology, an exhaustive account of what there is and how it hangs together. When Galileo concluded that mathematics was the key to the labyrinth of nature, he was prepared to treat all qualitative aspects of reality as sensational effects produced in us by a world that was essentially quantitative in character. This subjectivization of quality, its “introjection” into the mind, was perhaps initially driven by a reluctance to examine the abstractive preconditions of developing and deploying a quantitative vocabulary. Certain topics, among them sensed qualities, had to be set aside because they were not amenable to treatment in such terms. As Stroud emphasizes, to simply go on to suppose that such sensed qualities are not to be found in the world because they are not amenable to such treatment is unmotivated metaphysics, not a simple deliverance of any physical science.

The world-view to which the long arc of modern philosophy since Descartes bends is Materialism With A Bad Conscience, a Materialism continually bedeviled by the need to deal with apparently irreducible mental items. I believe this world-view to be the offspring of an introjective error; in effect, the mentalization of sensible form, finality and value. Hence the characteristic modernist accusation is that when we take sensible form, finality and value to be genuine features of the manifest we are thereby "projecting" aspects of our mental life onto an environment devoid of these features. David Hume went furthest in this Projectivist direction arguing that indeed even the very notion of an efficient cause was a projection of our habitual expectations that the regularly observed consequences of certain classes of events would continue. So far from these expectations constituting a practical knowledge of efficient causes, acquired over immense periods of time in the life of our species as it adapted to and with its complex causal environment, those expectations are merely appearances which we mistake for a mind-independent relation among the things themselves. Thus the manifest is traded in for the "manifest image of the world," an image interposed between a subject and deracinated environment.

Like dreaming, hallucination has been a formative trope for modern philosophy. The vivid, often tragic, breakdown in the mind’s apparent capacity to disclose reality has long served to support a paradoxical philosophical picture of sensory experience. This picture, which of late has shaped the paradigmatic empirical understanding the senses, displays sensory acts as already complete without the external world; complete in that the direct objects even of veridical sensory acts do not transcend what we could anyway hallucinate. Hallucination is thus the mother of Representationalism, which insists that it is mental intermediaries that make other..

The thesis is concerned with the outline of an ontology which admits only particulars and with the persistence of particulars through time. In Chapter 1 it is argued that a neglected class of particulars--the cases--have to be employed in order to solve the problem of universals, i.e., to give a satisfactory account of properties and kinds. In Chapter 2, two ways in which particulars could persist though time are distinguished. Difficulties are raised for the view that everything perdures through time, i.e., the view that each persisting thing is a sum of continuous and dependent temporal parts. Objections to the view that people perdure are presented in Chapter 3, objections to the effect that such a view cannot capture salient truths about the nature of experience and wrongly implies that our special concern for ourselves, our friends and our familiars is irrational. An alternative account of persisting particulars is provided in Chapter 4 by way of given a theory of substances. Finally, in Chapter 5, this alternative account is applied to the issue of personal identity and to the issue of the identity over time of living things in general. A Hylomorphic View of living things is sketched and briefly defended. ;Throughout, certain themes recur: essentialism is taken to be relatively unproblematic, various connections between time and modality are exploited, reductionism is regarded as bearing the onus of proof, characterless entities such as prime matter, substrata, bare particulars and haecceities are rejected and the differences between the animate and the inanimate are emphasized
