This article examines Leibniz's philosophy of causation with the aim of clarifying how causes are related to their effects. I argue that, much like J. L. Mackie's INUS conditions, Leibnizian causes are members of complex causal conditions. More precisely, Leibniz identifies causes with elements of complex causal conditions, where the complex condition as a whole is sufficient for the effect, and the cause is a necessary part of that condition. This conception of causation is able to incorporate Leibniz's many other (...) definitions of ‘cause’, thereby resolving what appear to be internal inconsistencies in his philosophy of science.

Leibniz's philosophy of time, often seen as a precursor to current forms of relationalism and causal theories of time, has rightly earned the admiration of his more recent counterparts in the philosophy of science. In this article, I examine Leibniz's philosophy of time from a new perspective: the role that tense and non-tensed temporal properties/relations play in it. Specifically, I argue that Leibniz's philosophy of time is best (and non-anachronistically) construed as a non-tensed theory of time, one that dispenses with (...) tensed temporal properties such as past, present, and future. In arguing for this thesis, I focus on the three facets of Leibniz's philosophy most relevant for evaluating his commitment to a B-theory of time: (1) the nature of change, (2) the reality of the future, and (3) the truth-conditions for tensed temporal statements. Despite prima facie evidence to the contrary, I show that a close examination of Leibniz's views on these topics provides compelling evidence for interpreting his philosophy of time as a B-theory of time.

As regards the question of the nature of time, Leibniz's account of monads raises the question of whether they have a temporal order and what this temporal order derives from. His account is generally taken to be an attempt to ground the asymmetric direction of time in a non-temporal sequence, such a chain of causes or reasons. The problem is whether such chains can ground temporal sequences without presupposing what it is that they are supposed to ground. Is his attempt (...) circular, as many commentators have argued? A case can be made that monadic states can be individuated without presupposing time, which would enable him to account for temporal sequences in terms of a non-temporal one. (shrink)

It has recently been suggested that, for Leibniz, temporal facts globally supervene on causal facts, with the result that worlds differing with respect to their causal facts can be indiscernible with respect to their temporal facts. Such an interpretation is at variance with more traditional readings of Leibniz’s causal theory of time, which hold that Leibniz reduces temporal facts to causal facts. In this article, I argue against the global supervenience construal of Leibniz’s philosophy of time. On the view of (...) Leibniz defended here, he adopts a non-modal reduction of time to events, a form of reductionism that entails a strong covariation between a world’s temporal facts and its causal facts. Consequently, worlds discernible with respect to their temporal facts must be discernible with respect to their causal facts, and worlds discernible with respect to their causal facts must be discernible with respect to their temporal facts. This position strongly favors the standard identificatory reduction of time to causation often imputed to Leibniz. (shrink)

Leibniz’s philosophy of time stands at the center not only of his metaphysics but also of his overall philosophy. For this reason, it has attracted the interest of Leibniz scholars and of philosophers of science alike. This concern notwithstanding, scant attention has been paid to what Leibniz himself takes to be a principal philosophical and theological issue in his philosophy of time: the world’s eternity. This article aims to redress this imbalance by ascertaining Leibniz’s views on the beginning, or beginninglessness, (...) of the world. Situating Leibniz’s views against the backdrop of ancient and medieval philosophy, I argue that he rejects traditional arguments seeking to prove the impossibility of an infinite temporal regress. At the same time, Leibniz equally eschews efforts to show that the world cannot have a beginning. Thus, Leibniz denies that the extent of the world’s duration can be decided on purely philosophical grounds. (shrink)
