How can symbols have meaning for a subject? Foundations of Understanding argues that this is the key question to ask about intentionality, or meaningful thought. It thus offers an alternative to currently popular linguistic models of intentionality, whose inadequacies are examined: the goal should be to explain, not how symbols, mental or otherwise, can refer to or mean states of affairs in the external world, but how they can mean something to us, the users. The essence of intentionality is shown to be conscious understanding, the roots of which lie in experiences of embodiment and goal-directed action. A developmental path is traced from a foundation of conscious understanding in the ability to perform basic actions, through the understanding of the concept of an objective, external world, to the understanding of language and abstract symbols. The work is interdisciplinary: data from the neurosciences and cognitive psychology, and the perspectives of phenomenologists such as Merleau-Ponty, are combined with traditional philosophical analysis. The book includes a chapter on the nature of conscious qualitative experience and its neural correlates. (Series A)"

In this paper I sketch an account of (a) the origin of the terms and concepts of folk psychology, and (b) the true nature of mental states. I argue that folk psychology is built on metaphors for the functioning physical body, and that mental states are neurological traces which serve as schematic ‘mental images’ of those same functions. Special attention is paid to the folk psychology of self-consciousness. In particular, I argue that the notion of introspection is mistaken, and I criticize recent claims of Patricia and Paul Churchland on this subject. I conclude by discussingrecent empirical evidence in support of my approach

The sensorimotor theory of cognition holds that human cognition, along with that of other animals, is determined by sensorimotor structures rather than by uniquely human linguistic structures. The theory has been offered to explain the use of bodily terminology in nonphysical contexts, and to recognize the role of experienced embodiment in cognition. This paper defends a version of the theory which specifies that reasoning makes use of mental models constructed by means of action-planning mechanisms. Evidence is offered from cognitive psychology, the neurosciences, and work in primatology and evolutionary theory. Further scientific and philosophical advantages of the theory are discussed: the theory is more parsimonious than its rival, and it offers better accounts of intrinsic intentionality and consciousness. The paper concludes with observations concerning the role of language in thought.

[opening paragraph]: It is easy to conceptualize a problem in a way that prevents a solution. If the conceptualization is entrenched in one's culture or profession, it may appear unalterable. But there is so much precedent for the discovery of fruitful reconceptualizations that in the case of most philosophical and scientific puzzles it is probably irrational ever to give up trying. The notion of qualia, understood as phenomenal properties of sensations that can exist as objects of experience for a conscious subject, is too recent in origin and too specialized in usage to warrant concluding that qualia cannot be understood in terms of physical processes. Humphrey offers an analysis of qualitative mental states that purportedly renders them commensurate with brain states, allowing them to be described in terms of the same dimensions. If his attempt is successful the conceptual gap between mind and body could be closed. Is it successful?

There is a distinction between phenomenal properties and the "phenomenality" of those properties: e.g. between what red is like and what it is like to experience red. To date, reductive accounts explain the former, but not the latter: Nagel is right that they leave something out. This paper attempts a reductive account of what it is like to have a perceptual experience. Four features of such experience are distinguished: the externality, unity, and self-awareness belonging to the content of conscious experience, and the phenomenon of awareness itself. It is argued that these features are accounted for in the work of recent scientists, including F. Crick, G. Edelman, C. Koch and V. Mountcastle. This account reinforces a common way of treating the "knowledge problem."
