Science aims to transform the subjectivity of individual observations and ideas into more objective and universal knowledge. Yet if there is any area in which first-person experience holds a particularly special and delicate role, it is the sciences of the mind. According to a widespread view, first-person methods were largely discarded from psychology after the fall of introspectionism a century ago and replaced by more objective behavioral measures, a step that some authors have begun to criticize. To examine whether these (...) views are sufficiently informed by actual scientific practice, we conducted a review of methodological approaches in the cognitive science literature. We found that reports of subjective experience are in fact still widely used in a broad variety of different experimental paradigms, both in studies that focus on subjective experience, and in those that make no explicit reference to it. Across these studies, we documented a diverse collection of approaches that leveraged first-person reports, ranging from button presses to unstructured interviews, while continuing to maximise experimental reproducibility. Common to these studies were subjects acting as sensors, intentionally communicating their experience to the experimenter, which we termed “second-person” methods. We conclude that, despite views to the contrary, first-person experience has always been and is still central to investigations of the mind even if it is not recognized as such. We suggest that the conversation ought to be reframed: instead of debating whether to accept subjects’ first-person knowledge we should discuss how best to do so. (shrink)

Agent-causal theories of free will, which rely on a non-reductionist account of the agent, have traditionally been associated with libertarianism. However, some authors have recently argued in favor of compatibilist agent-causal accounts. In this essay, I will show that such accounts cannot avoid serious problems of implausibility or incoherence. A careful analysis of the implications of non-reductionist views of the agent (event-causal or agent-causal as they may be) reveals that such views necessarily imply either the denial of the principle of (...) supervenience or the assumption of bottom-level indeterminism. I will contend that the former alternative comes at a high cost, while the latter is quite plausible. Therefore, providing that they accept the condition of the truth of indeterminism, non-reductionist accounts of the agent do not have to contradict our scientific worldview. Interestingly, while they should be taken seriously by anyone who is concerned with the passivity of the agent’s role under a reductionist scenario, non-reductivist accounts end up contributing an extra incompatibilist argument to the free will debate.

Spontaneous actions are preceded by brain signals that may sometimes be detected hundreds of milliseconds in advance of a subject's conscious intention to act. These signals have been claimed to reflect prior unconscious decisions, raising doubts about the causal role of conscious will. Murakami et al. (2014. Nat Neurosci 17: 1574–1582) have recently argued for a different interpretation. During a task in which rats spontaneously decided when to abort waiting, the authors recorded neurons in the secondary motor cortex. The neural (...) activity and relationship to action timing was parsimoniously explained using an integration-to-bound model, similar to those widely used to account for evidence-based decisions. In this model, the brain accumulates spontaneously occurring inputs voting for or against an action, but only commits to act once a certain threshold is crossed. The model explains how spontaneous decisions can be forecast (partially predicted) by neurons that reflect either the input or output of the integrator. It therefore presents an explicit hypothesis capable of rejecting the claim that such predictive signals imply unconscious decisions. We suggest that these results can inform the current debate on free will but must be considered with caution. (shrink)

Despite its recent popularity, Emergence is still a field where philosophers and physicists often talk past each other. In fact, while philosophical discussions focus mostly on ontological emergence, physical theory is inherently limited to the epistemological level and the impossibility of its conclusions to provide direct evidence for ontological claims is often underestimated. Nevertheless, the emergentist philosopher’s case against reductionist theories of how the different levels of reality are related to each other can still gain from the assessment of paradigmatic (...) examples of discontinuity between models in physics, even though their implications must be handled with care.

In the context of the free will debate, both compatibilists and event-causal libertarians consider that the agent’s mental states and events are what directly causes her decision to act. However, according to the ‘disappearing agent’ objection, if the agent is nothing over and above her physical and mental components, which ultimately bring about her decision, and that decision remains undetermined up to the moment when it is made, then it is a chancy and uncontrolled event. According to agent-causalism, this sort (...) of problem can be overcome if one realizes that the agent herself, as an irreducible substance, is the true originator of her actions. I’ll present arguments that favor this view. Event-causalists have countered that if the agent identifies with some of the inner states that play the self-determining causal role in bringing about the action, then it is as though the action was directly caused by herself. I’ll object that this is not a distinctive aspect of free agency. Agent-causalism has been criticized from most naturalistically inclined fronts, and it must address risks of implausibility, contradiction and unintelligibility. Even though I’ll acknowledge these challenges, I’ll still argue that libertarian free will cannot be defended by any reductionist alternative, and that agent-causalism does not conflict with contemporary science but only with some of its unproven assumptions.

Human behavior can range from automatic and even unconscious bodily movements to very elaborate and rational decisions. In this paper I develop a taxonomy based on the empirical analysis of the phenomenology associated with selected instances of different forms of behavior. The transition from sub-actional behavior to proper actions is shown to take place when the agent intervenes actively in the causal process leading from her mental states to the bodily movement by exercising her power to form intentions to act. (...) It is argued that this type of analysis could be helpful to agent-causal accounts of action and free will. (shrink)
