A familiar story suggests that Leibniz effectively develops two sep-arate systems, bridged by divine benevolence.3 On this account, physics is a science of appearances, metaphysics a science of reality, and God’s goodness assures us that our investigations of the former will somehow provide insight into the latter.

Leibniz was born on 1 July 1646, during the waning years of the Thirty Years’ War, in the Lutheran town of Leipzig. His father, Friedrich, was professor of moral philosophy at the University in Leipzig. His mother, Catherina Schmuck, was the daughter of a law professor. Leibniz grew up in an educated, and by all accounts, orthodox Lutheran environm...
Several key principles form the core of Leibniz’s philosophy. Though Leibniz never lists these serially in the manner of, for instance, the axioms of Spinoza’s Ethics, the principles nonetheless shape Leibniz’s thinking and ground his major claims. He refers to them throughout his writings and we shall refer to them throughout our discussion. Thoug...
a. Substantial Forms
One of the earliest intellectual projects Leibniz set for himself was to determine the proper relationship between the Aristotelian philosophy taught at his university in Leipzig and the new, mechanical philosophy espoused by thinkers like Galileo, Descartes, and Hobbes. Leibniz embraces modern, mechanical physics as the proper method for investigating nature, yet he is distinctive among 17thcentury thinkers for the depths of his efforts to retain several key metaphysical concepts of ancient...
b. Substance as Complete Concept
Though his defense of incorporeal substances allows Leibniz to partially reconcile pre-modern and modern thought, Leibniz still needs to articulate his own account of the nature of these substances. In §8 of the Discourse on Metaphysics, Leibniz takes up the task of defining individual substance. He begins with Aristotle’s definition, which states that when many things are said of a subject, yet it is said of nothing else, this subject is rightly called an individual substance. So, for instan...
c. Causality and Pre-Established Harmony
If each substance is complete in itself and requires no other substance to be understood, it follows that every finite substance is causally independent of all save God. Each created substance is, as Leibniz says, “like a world apart” (DM 14). But how can this be? How can Alexander defeat Darius without being related to, and thus in a sense dependent on, Darius? More broadly, how can Leibniz square his “world apart” language with our experience of living in a world with a plethora of cause an...
a. Leibniz’s Project
Leibniz ranks peace of mind as “the greatest cause of [his] philosophizing” (L 148). Central to Leibniz’s efforts to secure peace of mind is the thesis that we live in the best of all possible worlds, a position now commonly called Leibnizian optimism. Leibniz reasons that if we can assure ourselves that God acts in the best of all possible ways, then we can trust God’s justice and have true peace of mind. Of course, it is by no means self-evident that our world, which includes suffering and...
b. God
The thesis that God acts in the best of all possible ways follows from the notion of God as “an absolutely perfect being” (DM 1). Leibniz accepts Descartes’ ontological proof for the existence of God, which proves the existence of God by way of our idea of perfection, with one caveat. To Leibniz, Descartes leaves his proof open to the objection that God does not exist because God cannotexist. “An absolutely perfect being,” this objection posits, is a logical impossibility. So, Leibniz sets ou...
c. Possible Worlds and Optimism
As an absolutely perfect being, God acts in the most perfect fashion. To understand what this means for an account of creation and a defense of God’s justice, Leibniz turns to the idea of possible worlds. A possible world is any set of possible substances whose attributes are mutually consistent, or compatible, with one another. Monads whose mutual existence would not entail contradictions are said to be compossible and thus potential members of a common world. God, in his omniscience, survey...
a. Ideas and Knowledge
Leibniz’s epistemology begins with the distinction between clear and obscure ideas. An idea is clear when it allows one to recognize the thing represented, obscure when it does not. For example, one may have seen a gerbil and thus have an idea of what a gerbil is. However, if the next time she encounters a small rodent she cannot tell whether it is a gerbil or a hamster, then she possesses only an obscure idea of “gerbil.” By contrast, when one’s idea suffices to reliably distinguish one kind...
b. Innate Ideas
In the New Essays on Human Understanding, Leibniz takes aim at Locke’s depiction of the mind as a tabula rasa, or blank tablet, needing external impressions to furnish it with the contents of its reasoning. In opposition to this conception of the mind and cognition, Leibniz affirms the existence of innate ideas. In one sense, Leibniz’s theory of substance obviously commits him to some conception of innate ideas. If monads have no “windows” through which they interact with other substances, th...
c. Petites Perceptions
One of the more original elements of Leibniz’s epistemology is his theory of petites perceptions. There are hundreds of indications leading us to conclude that at every moment there is in us an infinity of perceptions, unaccompanied by awareness or reflection; that is, of alterations in the soul itself, of which we are unaware because these impressions are either too minute and too numerous, or else too unvarying, so that they are not sufficiently distinctive on their own. But when they are c...
Of the traditional major content areas of philosophy, ethics is perhaps the only one to which Leibniz is generally not considered to have made significant contribution. Certainly he does not share the reputation as an ethicist enjoyed by early modern thinkers Spinoza, Hume, and Kant, nor does he share the influence in political philosophy had by Lo...
a. Primary Sources: Leibniz Texts and Translations
The standard critical edition of Leibniz’s writings is G.W. Leibniz: Sämtliche Schriften und Briefe, edited by the Deutsche Akademie der Wissenschaften (Berlin: Academy Verlag, 1923- ). The Akademie edition is still in production. Other useful editions of Leibniz’s writings in their original languages are those of C. I. Gerhardt (Die Philosophischen Schriften von Leibniz. 7 vols. 1875-1890) and Ludovici Dutens (Gottfried Wilhelm Leibniz: Opera Omnia. Hildesheim: Georg Olms Verlag, 1989). Refe...

Leibniz's best known contribution to metaphysics is his theory of monads, as exposited in Monadologie. He proposes his theory that the universe is made of an infinite number of simple substances known as monads. [74]

6. Recalling the theory of the TMA later in life, Leibniz writes: … I showed that it ought to follow that the conatus of a body entering into a collision, however small it might be, would be impressed on the whole receiving body, however larger it might be, and thus, that the largest body at rest would be carried off by a colliding body however small it might be, without regarding it at all ...
28 de ene. de 2013 · This chapter discusses Leibniz’s earliest work on physical questions. It begins with how his discovery of contemporary publications on the laws of motion prompted him to investigate the topic for himself, leading him to make a fundamental distinction between pure theory and natural phenomena.
5 de ago. de 2021 · The first principles are, according to Leibniz, anchored in the mind of God himself and govern both reality and thought. However, it should be noted that the apparent formal nature of these principles should not be understood from the vantage point of modern logic.
