Aptness and means-end coherence: a dominance argument for causal decision theory

Why should we be means-end rational? Why care whether someone’s mental states exhibit certain formal patterns, like the ones formalized in causal decision theory? This paper establishes a dominance argument for these constraints in a finite setting. If you violate the norms of causal decision theory, then your desires will be aptness dominated. That is, there will be some alternative set of desires that you could have had, which would be more apt (closer to the actual values fixed by your sensibility/ what you intrinsically care about) no matter which world is actual. If we care about having apt desires, then, we should never let ourselves violate these norms of means-end rationality. This argument shares a form with now-standard accuracy arguments for probabilism, opening up a new terrain for that discussion. I show that the foundational assumptions about the shape of accuracy and of aptness required to run the arguments for means-end rationality and for probabilism run closely parallel. I show the argument is robust under different theories of subjective actual value, including nonclassical treatments of indeterminacy in actual value; I show the argument may (but need not!) be generalized to objective theories of value. The upshot is that aptness-domination arguments for decision theories should be added to the philosophical playbook.

Self-Knowledge Requirements and Moore's Paradox

Is self-knowledge a requirement of rationality, like consistency, or means-ends coherence? Many claim so, citing the evident impropriety of asserting, and the alleged irrationality of believing, Moore-paradoxical propositions of the form < p, but I don't believe that p>. If there were nothing irrational about failing to know one's own beliefs, they claim, then there would be nothing irrational about Moore-paradoxical assertions or beliefs. This article considers a few ways the data surrounding Moore's paradox might be marshaled to support rational requirements to know one's beliefs, and finds that none succeed.

An alternative norm of intention consistency.

In this paper, I formulate a norm of intention consistency that is immune to the kind of cases that have been put forth to argue either that rationality does not require consistency between an agent's intentions, or that, if it does, then rationality is not normative. The norm I formulate mimics refinements that have been made to the norm of means‐end coherence in response to cases where, intuitively, you need not be irrational when you intend an end e, despite not intending the means m you believe to be necessary for e, because you do not believe that intending m is necessary for e. Similarly, according to the norm I put forth, if you intend e, and believe that e is inconsistent with e*, you need not be irrational if you also intend e*, as long as you do not believe that intending e* is inconsistent with e.

Précis of planning, time, and self-governance

ABSTRACT Précis of Michael E. Bratman, Planning, Time, and Self-Governance: Essays in Practical Rationality. The planning theory highlights our capacity to settle on future courses of action in ways that Philosophy Department, shape on-going thought and action. Given our resource limits, our prior plans exhibit a characteristic partiality. Given this partiality, pressures for means-end coherence lead to problems of means. In solving these problems, one is constrained by pressures of consistency and intention stability, pressures that induce a filter of admissibility on solutions. Such plan-infused functioning involves guidance of practical thinking by norms of intention rationality, including norms of consistency, agglomerativity, means-end coherence, and stability over time. These essays focus on questions about the nature of and support for these norms. The essays aim to incorporate but go beyond a two-tier pragmatic rationale for these norms. They seek a view between a skeptical ‘myth theory’ and a cognitivist view that sees these norms as a matter of theoretical rationality. The essays argue that these norms track conditions of a planning agent’s self-governance, both at a time and over time; and the essays explain the reflective significance of this tracking in part by appeal to our entrenched, though contingent, end of our diachronic self-governance.

On self-governance over time

ABSTRACT In Planning, Time, and Self-Governanace, Bratman argues that the notion of self-governance plays an important role in grounding the rational principles such as means-ends coherence in the synchronic case, and principles of stability and coherence through time in the case of self-governance over time. In this paper, I grant Bratman’s claim for the synchronic case, however I argue that it is not clear that one can extend the reasoning to the diachronic case. More specifically, I raise a number of doubts about whether any notion of diachronic self-governance can play the role in the theory of practical rationality that Bratman assigns to it.

Requirements of intention in light of belief

Much work in the philosophy of action in the last few decades has focused on the elucidation and justification of a series of purported norms of practical rationality that concern the presence or absence of intention in light of belief, and that demand a kind of structural coherence in the psychology of an agent. Examples of such norms (all roughly formulated) include: Intention Detachment, which proscribes intending to do something in case some condition obtains, believing that such condition obtains, and not intending to do that thing; Intention-Belief Consistency, which proscribes intending to do what you believe you will not do; Intention Consistency, which proscribes intending each of two ends you believe to be inconsistent; and Means-End Coherence, which proscribes intending an end and not intending the means you believe to be implied by your end. In this paper, I present a series of examples that show that these requirements are not genuine requirements of rationality. The reason for this is simple: these requirements concern the presence or absence of intention in light of all-out belief. Rational agents like us, however, do not, and in fact should not, always form or revise their intentions in light of what they all-out believe. When such agents do not form or revise their intentions in light of what they all-out believe, they need not be irrational if they do not conform to these requirements.

Rational Planning Agency

AbstractOur planning agency contributes to our lives in fundamental ways. Prior partial plans settle practical questions about the future. They thereby pose problems of means, filter solutions to those problems, and guide action. This plan-infused background frames our practical thinking in ways that cohere with our resource limits and help organize our lives, both over time and socially. And these forms of practical thinking involve guidance by norms of plan rationality, including norms of plan consistency, means-end coherence, and stability over time.But why are these norms of rationality? Would these norms be stable under a planning agent's reflection? I try to answer these questions in a way that responds to a skeptical challenge. While I highlight pragmatic reasons for being a planning agent, these need to be supplemented fully to explain the force of these norms in the particular case. I argue that the needed further rationale appeals to the idea that these norms track certain conditions of a planning agent's self-governance, both at a time and over time. With respect to diachronic plan rationality, this approach leads to a modest plan conservatism.

Intention rationality

The practical thought of planning agents is subject to distinctive rationality norms. In particular, there are norms of intention consistency and of means–end coherence. I discuss the normative significance of these norms and their relation to practical reasons. I seek a path between views that see these norms as, at bottom, norms of theoretical rationality, and views that see the idea that these norms have distinctive normative significance as a ‘myth’. And I seek to distinguish these norms from principles about the transmission of practical reasons. In the end, my view draws on claims about what is involved in being a self-governing planning agent.

Means-end coherence, stringency, and subjective reasons

Intentions matter. They have some kind of normative impact on our agency. Something goes wrong when an agent intends some end and fails to carry out the means she believes to be necessary for it, and something goes right when, intending the end, she adopts the means she thinks are required. This has even been claimed to be one of the only uncontroversial truths in ethical theory. But not only is there widespread disagreement about why this is so, there is widespread disagreement about in what sense it is so. In this paper I explore an underdeveloped answer to the question of in what sense it is so, and argue that resolving an apparent difficulty with this view leads to an attractive picture about why it is so.
