Abstract

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Movements of the Mind. A Theory of Attention, Intention and Action by Wayne WuDiego D’AngeloWU, Wayne. Movements of the Mind. A Theory of Attention, Intention and Action. Oxford: Oxford University Press, 2023. 257 pp. Cloth, $80.00Wayne Wu presented a theory of attention as selection-for-action in 2014. According to this theory, given a behavioral space in which the agent has multiple inputs and outputs to choose from, attention involves the selection of a particular course of action, that is, of certain outputs based on certain inputs. In the present work Wu puts to use the selection-for-action theory to shed light on the broader topic of the “movements of the mind”: intentionality and action. Action and movement are mostly not intended as bodily movement: By focusing on mental actions Wu aims to simplify philosophical explanations. His overall theoretical approach remains consistent with his work on attention, which involves a quest to develop rigorous philosophical concepts while incorporating insights from the empirical sciences. Interestingly, biology takes precedence over cognitive sciences and psychology for him; he says, “I aspire to a biology of agency” in which philosophical analysis must respond to “empirical friction.” In this framework, this book puts forth four main claims. The first concerns the general structure of action—action arises from solving a selection problem. Second, intentional actions can be differentiated from unintentional actions using the concepts of automaticity and control. Third, Wu argues that attention is a necessary aspect of every theory of action. Fourth, he claims that intention is practical memory for action. These four are woven throughout the different chapters of his book.The first part analyzes the structure of action along three axes: how the agent “takes things to be” as the basis for selection, the agent’s response to those things, and the biases that explain the link between perceptions and responses. In the second part, Wu presents a theory of intention as practical memory. The theory is surprising, as Wu himself acknowledges when he says, “The approach to intention will, I think, jar many readers.” And indeed, it does, but Wu provides strong arguments, and future work will determine if the theory is feasible. The third part of the book explores the implications of his theory of action for specific forms and aspects of action; the first chapter in this section deals with automaticity and biases, [End Page 734] the second deals with deductive reasoning, and the third deals with introspection.According to Wu’s theory, action involves a complex combination of elements. The agent is faced with many inputs and potential outputs within a behavioral space. She takes inputs in a certain way: The way she sees things is influenced by myriad aspects, such as intentions and biases of various forms. Action and intending to act are solutions to the problem of selecting appropriate inputs and outputs. Wu thematizes the role of attention in this process of selection. Attention comes in three different forms. It can be an action itself (“attending,” for example, in searching for something); it can mean “vigilance” as readiness to act; and most importantly, attention is “mental guidance.” Every action is guided by attention insofar as a selection problem must be solved: Attention is guiding when perceptual input “plays a functional role of guiding.” Attention also shapes the agent’s actions through remembering, and remembering in turn is nothing else then attending to remembered content. This attended content provides the agent with biases and reasons to select a particular course of action. Therefore, intending to act is nothing else than practical memory, that is, memory put to work in the choice of actions.One particular type of action that is crucially important for philosophical research is introspection. According to Wu, introspection, like every kind of mental action, is not entirely reliable—as some theories would have it—or entirely unreliable but, instead, depends on context. Like any other action, introspection follows the same guiding principle, attention, specifically, perceptual attention. Therefore, introspection is a particular type of perceptual experience where attention is focused on one’s own mental states. In this way, Wu establishes criteria for veridical introspective reports, such...
