Reasons-responsiveness, action and control: an event-causal account of agency

In this thesis, I aim to contribute to the reconciliation of two ways of looking at human agency—from the perspective of agents themselves, and from a detached, scientific perspective—by combining resources from the free will literature and the action theory literature. I will show that we can preserve most of our ordinary conception and intuitions about human agency rooted in common sense even if we suppose the truth of determinism and a universal event-causal framework. Below are the two key claims defended in the thesis.
(i.) Free Agency (which is required by moral responsibility) is the ability to respond to reasons.
(ii.) To exercise free agency is to act for reasons; while acting for reasons can be captured within an event-causal framework.
Accordingly, I will defend two theories concerning human agency: one is the reasons-responsiveness theory of free will and moral responsibility; the other is the causal theory of action. The first theory helps to show that free will and moral responsibility can exist in a deterministic world; while the second theory helps to resolve the tension between action and the event-causal framework. Moreover, I will integrate these two theories. This integration aims to provide a more complete picture of human agency. According to this picture, the exercising of human agency can be taken as a continuum—ranging from basic voluntary control to high-level actions which merit moral evaluation; this continuum can be captured within a unified theoretical framework, namely, the event-causal framework. That is, the important features of human agency, from basic purposive actions to free and responsible actions can be explained in terms of event-causations.
In doing so, I advance a new account of reasons-responsiveness theory, deflate the problem of causal deviance by developing a novel account of control, and solve the problem of disappearing agency by developing an account of agent’s participation in her action. I will also investigate several kinds of phenomenology of agency which purportedly speak against the event-causal account of action. The integrated theory developed shows us how our agency, in all its complexity, fits into a naturalistic picture of the world.
