Over the past few years, the tree model of time has been widely employed to deal with issues concerning the semantics of tensed discourse. The thought that has motivated its adoption is that the most plausible way to make sense of indeterminism is to conceive of future possibilities as branches that depart from a common trunk, constituted by the past and the present. However, the thought still needs to be further articulated and defended, and several important questions remain open, such (...) as the question of how actuality can be understood and formally represented in a branching framework. The present volume is intended to be a 360 degree reflection on the tree model. The contributions is gathers concern the model and its alternatives, both from a semantic and from a metaphysical point of view. ​. (shrink)

What difference do our decisions make to our reasons for action and the rationality of our actions? There are two questions here, and good grounds for answering them differently. However, it still makes sense to discuss them together. By thinking about the relationships that reasons and rationality bear to decisions, we may be able to cast light on the relationship that reasons and rationality bear to each other.

Just as bodily actions are things you do with your body, mental actions are things you do with your mind. Both are different from things that merely happen to you. Where does the idea of mental action come from? What are mental actions? And why do they matter in philosophy? These are the three main questions answered in this paper. Section 1 introduces mental action through a brief history of the topic in philosophy. Section 2 explains what it is to (...) be a mental action in terms of intentional action. Section 3 argues that the fact that we can perform mental actions has some striking consequences concerning mental content. Section 4 shows how mental action helps to explain some important facts about self-knowledge and the normativity of thought. The conclusion mentions two further fruitful avenues for philosophical research on mental action. (shrink)

I develop an interdisciplinary framework for understanding the nature of agents and agency that is compatible with recent developments in the metaphysics of science and that also does justice to the mechanistic and normative characteristics of agents and agency as they are understood in moral philosophy, social psychology, neuroscience, robotics, and economics. The framework I develop is internal perspectivalist. That is to say, it counts agents as real in a perspective-dependent way, but not in a way that depends on an (...) external perspective. Whether or not something counts as an agent depends on whether it is able to have a certain kind of perspective. My approach differs from many others by treating possession of a perspective as more basic than the possession of agency, representational content/vehicles, cognition, intentions, goals, concepts, or mental or psychological states; these latter capabilities require the former, not the other way around. I explain what it means for a system to be able to have a perspective at all, beginning with simple cases in biology, and show how self-contained normative perspectives about proper function and control can emerge from mechanisms with relatively simple dynamics. I then describe how increasingly complex control architectures can become organized that allow for more complex perspectives that approach agency. Next, I provide my own account of the kind of perspective that is necessary for agency itself, the goal being to provide a reference against which other accounts can be compared. Finally, I introduce a crucial distinction that is necessary for understanding human agency: that between inclinational and committal agency, and venture a hypothesis about how the normative perspective underlying committal agency might be mechanistically realized.

The volitional theory of human action has formed a basis for a prominent account of voluntary behavior since at least Aquinas. But in the twentieth century the notions of will and volition lost much of their popularity in both philosophy and psychology. Gilbert Ryle’s devastating attack on the concept of will, and especially the doctrine of volition, has had lingering effects evident in the widespread hostility and skepticism towards the will and volition. Since the 1970s, however, the volitional theory has (...) received some renewed interest in the philosophy of action. Some philosophers even consider that ‘in current philosophy of action it is perhaps the most widely held view, at least regarding the immediate antecedents of action.’. (shrink)

The first half of this paper is an attemptto conceptualize and understand the paradoxicalnotion of ``passive action''''. The strategy is toconstrue passive action in the context ofemotional behavior, with the purpose toestablish it as a conceivable and conceptuallycoherent category. In the second half of thispaper, the implications of passive action forcausal theories of action are examined. I arguethat Alfred Mele''s defense of causalism isunsuccessful and that causalism may lack theresource to account for passive action.Following Harry Frankfurt, I suggest analternative way (...) of understanding the nature ofaction that can accommodate passive action.

The concept of volition has a long history in Western thought, but is looked upon unfavorably in contemporary philosophy and psychology. This paper proposes and elaborates a unifying conception of volition, which views volition as a mediating executive mental process that bridges the gaps between an agent's deliberation, decision and voluntary bodily action. Then the paper critically examines three major skeptical arguments against volition: volition is a mystery, volition is an illusion, and volition is a fundamentally flawed conception that leads (...) to infinite regress. It is shown that all these charges are untenable and the arguments are far from decisive to dismiss the concept of volition. In addition, it is suggested that a naturalistic approach, which takes philosophical inquiry as continuous with the scientific study of volition, is a promising way to demystify volition. (shrink)

In this paper, it is examined how neuroscience can help to understand the nature of volition by addressing the question whether volitions can be localized in the brain. Volitions, as acts of the will, are special mental events or activities by which an agent consciously and actively exercises her agency to voluntarily direct her thoughts and actions. If we can pinpoint when and where volitional events or activities occur in the brain and find out their neural underpinnings, this can substantively (...) aid to demystify the concept of volition. After first discussing some methodological issues regarding whether it is possible to locate volition in the brain, various approaches by which neuroscientists and psychologists explore the neural correlates and substrates of volition are examined. Although different psychological conceptualizations of volition shape different perspectives toward understanding the functions of volition, the explorations of the neural basis of volition converge on certain common brain areas and structures. A unifying conception of volition that helps to make better sense of recent empirical findings is then suggested. (shrink)
