Leibniz maintains that even though God’s intellect contains all possibles, some of these possibles are not compossible. This incompossibility of some possibles is supposed to explain which collections of possibles are possible worlds and why God does not actualize the collection of all possibles. In order to fully understand how this works, we need to establish what precisely Leibniz takes to be the source of incompossibility, that is, which divine attribute or faculty gives rise to the incompossibility of certain possibles. Different interpretations answer this question in different ways. This chapter explores the role that God’s faculties play on some of the standard interpretations of Leibniz’s notion of incompossibility and argues that we are faced with a dilemma: even though incompossibility must somehow arise from God’s faculties, none of the faculties usually distinguished seems up to the task. To escape this dilemma, we need to revise the traditional understanding of the divine faculties. More specifically, we need to recognize wisdom as an attribute that is distinct from intellect, power, and will and that is the source of incompossibility.

Leibniz is almost unique among early modern philosophers in giving final causation a central place in his metaphysical system. All changes in created substances, according to Leibniz, have final causes, that is, occur for the sake of some end. There is, however, no consensus among commentators about the details of Leibniz's views on final causation. The least perfect types of changes that created substances undergo are especially puzzling because those changes seem radically different from paradigmatic instances of final causation. Building on my more general discussion of efficient and final causation in ‘Leibniz on Causation – Part 1,’ I will examine and assess some of the rival interpretations of Leibniz's account of final causation

Leibniz was obsessed with freedom. He turns to this topic again and again throughout his long career. And what he has to say about freedom is much more resourceful and inventive than typically acknowledged. While building on medieval theories—for instance by describing freedom in terms of the relation between the agent’s will and intellect—he also adds radically new elements and even anticipates some views that are popular today. The combination of theses about free will that Leibniz endorses in his mature writings is unusual and may at first appear inconsistent: (a) he claims that some of our actions are free, (b) he links free agency closely to agent causation and in fact appears to deny that there is event causation; (c) he accepts a form of determinism. In other words, Leibniz endorses what we can describe as an agent-causal compatibilist theory of freedom. The three theses may seem to be in tension not only because proponents of agent causation views are typically incompatibilists, but also because determinism is often defined in a way that presupposes event causation. As we will see soon, however, the tension is merely apparent. Leibniz’s version of agent-causal compatibilism is perfectly coherent and has some unique advantages over rival accounts.

This book presents a comprehensive examination of Gottfried Leibniz's views on the nature of agents and their actions. Julia Jorati offers a fresh look at controversial topics including Leibniz's doctrines of teleology, the causation of spontaneous changes within substances, divine concurrence, freedom, and contingency, and also discusses widely neglected issues such as his theories of moral responsibility, control, attributability, and compulsion. Rather than focusing exclusively on human agency, she explores the activities of non-rational substances and the differences between distinctive types of actions, showing how the will, appetitions, and teleology are key to Leibniz's discussions of agency. Her book reveals that Leibniz has a nuanced and compelling philosophy of action which has relevance for present-day discussions of agency. It will be of interest to scholars and students of early modern philosophy as well as to metaphysicians and philosophers of action.

Leibniz holds that creatures require divine concurrence for all their actions, and that this concurrence is 'special,' that is, directed at the particular qualities of each action. This gives rise to two potential problems. The first is the problem of explaining why special concurrence does not make God a co-author of creaturely actions. Second, divine concurrence may seem incompatible with the central Leibnizian doctrine that substances must act spontaneously, or independently of other substances. Concurrence, in other words, may appear to jeopardize creaturely substancehood. I argue that Leibniz can solve both of these problems by invoking final and formal causation. The creature is the sole author of its actions because it alone contributes the formal and final cause to these actions. Similarly, because it contributes the formal and final cause, the creature possesses what I call explanatory spontaneity. Leibniz, I contend, considers this type of spontaneity sufficient for substancehood
