Ordinary people make moral judgments that are consistent with philosophical and legal principles. Do those judgments derive from the controlled application of principles, or do the principles derive from automatic judgments? As a case study, we explore the tendency to judge harmful actions morally worse than harmful omissions (the ‘omission effect’) using fMRI. Because ordinary people readily and spontaneously articulate this moral distinction it has been suggested that principled reasoning may drive subsequent judgments. If so, people who exhibit the largest omission effect should exhibit the greatest activation in regions associated with controlled cognition. Yet, we observed the opposite relationship: activation in the frontoparietal control network was associated with condemning harmful omissions—that is, with overriding the omission effect. These data suggest that the omission effect arises automatically, without the application of controlled cognition. However, controlled cognition is apparently used to overcome automatic judgment processes in order to condemn harmful omissions.

Traditional theories define truth via correspondence, pragmatics, or coherence. This preprint paper argues that coherence is not merely one rival theory but the structural precondition enabling correspondence and pragmatic success. Coherence is formalized across three interconnected levels: epistemic (mutual justification among beliefs), ontological (invariant relational structures constituting identity), and dynamical (stability under recursive transformation). Objectivity emerges as invariance across coherent systems, exemplified by the Cartesian cogito. Sustained coherence under indefinite iteration requires a scale-invariant self-consistency. This can be illustratively modeled by the golden ratio ϕ as an extremal fixed point that maximizes stability in recursive dynamics. This yields a fractal attractor space of maximally coherent trajectories (a formalized model of recursive stability), offering a unified lens for understanding truth, identity, and reality as dynamically stabilized invariants.

Intuitions play an important role in the debate on the causal status of high‐level properties. For instance, Kim has claimed that his “exclusion argument” relies on “a perfectly intuitive … understanding of the causal relation.” We report the results of three experiments examining whether laypeople really have the relevant intuitions. We find little support for Kim's view and the principles on which it relies. Instead, we find that laypeople are willing to count both a multiply realized property and its realizers as causes, and regard the systematic overdetermination implied by this view as unproblematic.

Thesis file is unavailable. Decisions are performatives - or at least, they share important features with performative utterances that can elucidate our theory of what type of thought they are, and what they do. Namely, decisions have an analogous force to that of performatives, where the force of a propositional attitude or utterance is constituted by (i) its point, or purpose, which is mainly a matter of its direction-of-fit, and (ii) its felicity conditions. The force of both decisions and performatives is to bring into being the states of affairs represented in their intentional contents, merely in virtue of the decision or performative’s occurrence and the satisfaction of the felicity conditions they presuppose. The first chapter of the thesis explicates this general framework, and the second and third attempt to show some of the work it can do for a theory of decisions.

On the one hand, judgments about taste and aesthetics seem somehow more subjective than other judgments—those about matters of descriptive fact, for instance. On the other hand, it seems we sometimes genuinely disagree in virtue of making different taste and aesthetic judgments. And many theorists think that in order to ground genuine disagreement, judgments must have contradictory contents—contents that cannot both be true. Most semantic theories of taste and aesthetic predicates, including contextualism and truth relativism, attempt to account for the comparative subjectivity of taste and aesthetic judgments while preserving this supposed contradiction datum. This chapter presents results from three studies suggesting that while most people think they can disagree about taste and aesthetics, this is not because they think their judgments in this domain preclude one another’s truth. Indeed, the results suggest that many people do not regard judgments of taste and aesthetics as truth-apt at all.

Within philosophy of action, there are three broad views about what, in addition to beliefs, answer the question of “what to do?” and so determine an agent’s motivation: desires, judgments about values/reasons, or states of the will, such as intentions. We argue that recent work in decision theory vindicates the volitionalist. “What to do?” isn’t settled by “what do I value” or “what reasons are there?” Rational motivation further requires determining how to trade off the possibility of a good outcome against the possibility of a bad one—i.e., determining how much of a risk to take. The risk attitudes that embody this tradeoff seem best understood as intentions: as self-governing policies to weight desires or reasons in certain ways. That we need to settle our risk attitudes before making most decisions corroborates Bratman’s claim that self-governing policies are required for resolving impasses of evaluative and normative underdetermination. Moreover, far from being rare or confined to tie-breakings, cases that are underdetermined but for one’s risk attitudes are typical of everyday decision-making. The will is required for most rational action.

The standard view in epistemology is that propositional knowledge entails belief. Positive arguments are seldom given for this entailment thesis, however; instead, its truth is typically assumed. Against the entailment thesis, Myers-Schulz and Schwitzgebel (Noûs, forthcoming) report that a non-trivial percentage of people think that there can be propositional knowledge without belief. In this paper, we add further fuel to the fire, presenting the results of four new studies. Based on our results, we argue that the entailment thesis does not deserve the default status that it is typically granted. We conclude by considering the alternative account of knowledge that Myers-Schulz and Schwitzgebel propose to explain their results, arguing that it does not explain ours. In its place we offer a different explanation of both sets of findings—the conviction account, according to which belief, but not knowledge, requires mental assent

Virtue ethics prescribes cultivating global and behaviorally efficacious character traits, but John Doris and others argue that situationist social psychology shows this to be infeasible. Here, I show how certain versions of virtue ethics that ‘go mental’ can withstand this challenge as well as Doris’ further objections. The defense turns on an account of which psychological materials constitute character traits and which the situationist research shows to be problematically variable. Many situationist results may be driven by impulsive akrasia produced by low-level , emotionally induced ignorance about one’s situation, and some may be driven by a further subtype: modal akrasia. Many subjects in the infamous Milgram experiments, e.g., seem to have recognized what the virtuous thing to do was and that they should do it, and only failed to do it because their emotions prevented them from seeing that they could. If the primary constituents of character traits are higher-level mental dispositions involved in deliberation, though, then the results don’t show that these psychological materials are problematically variable

The debate between compatibilists and incompatibilists depends in large part on what ordinary people mean by ‘free will’, a matter on which previous experimental philosophy studies have yielded conflicting results. In Nahmias, Morris, Nadelhoffer, and Turner (2005, 2006), most participants judged that agents in deterministic scenarios could have free will and be morally responsible. Nichols and Knobe (2007), though, suggest that these apparent compatibilist responses are performance errors produced by using concrete scenarios, and that their abstract scenarios reveal the folk theory of free will for what it actually is—incompatibilist. Here, we argue that the results of two new studies suggest just the opposite. Most participants only give apparent incompatibilist judgments when they mistakenly interpret determinism to imply that agents’ mental states are bypassed in the causal chains that lead to their behavior. Determinism does not entail bypassing, so these responses do not reflect genuine incompatibilist intuitions. When participants understand what determinism does mean, the vast majority take it to be compatible with free will. Further results indicate that most people’s concepts of choice and the ability to do otherwise do not commit them to incompatibilism, either, putting pressure on incompatibilist arguments that rely on transfer principles, such as the Consequence Argument. We discuss the implications of these findings for philosophical debates about free will, and suggest that incompatibilism appears to be either false, or else a thesis about something other than what most people mean by ‘free will’.

We discuss recent work in experimental philosophy on free will and moral responsibility and then present a new study. Our results suggest an error theory for incompatibilist intuitions. Most laypersons who take determinism to preclude free will and moral responsibility apparently do so because they mistakenly interpret determinism to involve fatalism or “bypassing” of agents’ relevant mental states. People who do not misunderstand determinism in this way tend to see it as compatible with free will and responsibility. We discuss why these results pose a challenge to incompatibilists.

If someone brings about an outcome without intending to, is she causally and morally responsible for it? What if she acts intentionally, but as the result of manipulation by another agent? Previous research has shown that an agent's mental states can affect attributions of causal and moral responsibility to that agent, but little is known about what effect one agent's mental states can have on attributions to another agent. In Experiment 1, we replicate findings that manipulation lowers attributions of responsibility to manipulated agents. Experiments 2–7 isolate which features of manipulation drive this effect, a crucial issue for both philosophical debates about free will and attributions of responsibility in situations involving social influence more generally. Our results suggest that “bypassing” a manipulated agent's mental states generates the greatest reduction in responsibility, and we explain our results in terms of the effects that one agent's mental states can have on the counterfactual relations between another agent and an outcome.
