Here's some work I drew from:

• Charles Taylor, What is Human Agency? (1977)
• Ruth Chang, All Things Considered (2004)
• James J Gibson, The Senses Considered as Perceptual Systems (1966)
• David Velleman, Practical Reflection (1989)
• Amartya Sen, Equality of What? (1979)
• Elizabeth Anderson, Value in Ethics and Economics (1993)

One difference in my approach: in modern philosophy, especially meta-ethics, values are often considered as evaluative criteria or attitudes. Here, I treat them as policies, but I think these definitions are interchangeable. An evaluative attitude or criterion can be viewed as something a person does when making an evaluation or choice.* can do the same work

So, DAPs are a mapping of work by other philosophers into the realm of action, including especially work by Charles Taylor (who calls them "strong evaluative terms"), and Ruth Chang (who calls them "values").*

My mapping of these attitudes or criteria into the realm of action is probably descended from James J Gibson's theory of affordances. But I doubt it would have occurred to me without the precedent of a similar theory, bridging criteria and action, by J David Velleman, wherein self-understandings (including values) become tools used for choice-making.

Other, closely-related strands of work are those of Amartya Sen, Martha Nussbaum, and Elizabeth Anderson.

• One difficulty in using the word "value" is that, in my sense, a value is quite distinct from a norm. If norms are notions of good behavior that are socially enforced, then this makes them strategic for agents to comply with. It means they are complied with for those strategic reasons, rather than because they are part of someone's concept of living well, and this puts them outside the definition of values used here. I believe many influential philosophers—including Nietzsche, Foucault, Kant, and Hume—used the term 'value' in a way that also covers norms.* And the relevant literatures in economics and sociology, one often sees the construction "values and norms" without an attempt to pry the two apart.
