This paper presents Sen's theory of agency, focusing on the role of commitment in this theory as both problematic and potentially illuminating. His account of some commitments as goal-displacing gives rise to a dilemma given the standard philosophical theory of agency.Eithercommitment-motivated actions are externally motivated, in which case they are not expressions of agency,orsuch actions are internally motivated, in which case the commitment is not goal-displacing. I resolve this dilemma and accommodate his view of commitment as motivation by developing a (...) broader descriptive theory of agency, which recognizes both agent goal-directed and goal-displacing commitments. I propose a type of goal-displacing commitment, which I call ‘tacit commitment’, that can be seen to fit between the horns. Tacit commitments regulate behaviour without being made conscious and explicit. This resolution suggests a means of bridging the normative/descriptive gap in social-scientific explanation. (shrink)

This is a comprehensive anthology of works concerning the nature of economics as a science, including classic texts and essays exploring specific branches and schools of economics. Apart from the classics, most of the selections in the third edition are new, as are the introduction and bibliography. No other anthology spans the whole field and offers a comprehensive introduction to questions about economic methodology.

I develop an interdisciplinary framework for understanding the nature of agents and agency that is compatible with recent developments in the metaphysics of science and that also does justice to the mechanistic and normative characteristics of agents and agency as they are understood in moral philosophy, social psychology, neuroscience, robotics, and economics. The framework I develop is internal perspectivalist. That is to say, it counts agents as real in a perspective-dependent way, but not in a way that depends on an (...) external perspective. Whether or not something counts as an agent depends on whether it is able to have a certain kind of perspective. My approach differs from many others by treating possession of a perspective as more basic than the possession of agency, representational content/vehicles, cognition, intentions, goals, concepts, or mental or psychological states; these latter capabilities require the former, not the other way around. I explain what it means for a system to be able to have a perspective at all, beginning with simple cases in biology, and show how self-contained normative perspectives about proper function and control can emerge from mechanisms with relatively simple dynamics. I then describe how increasingly complex control architectures can become organized that allow for more complex perspectives that approach agency. Next, I provide my own account of the kind of perspective that is necessary for agency itself, the goal being to provide a reference against which other accounts can be compared. Finally, I introduce a crucial distinction that is necessary for understanding human agency: that between inclinational and committal agency, and venture a hypothesis about how the normative perspective underlying committal agency might be mechanistically realized.
