A philosophy written in the mountains #407

In an era obsessed with immediate utility, Andreas Matthias presents a startling counter-narrative: one of history's most profound philosophical systems was born not in a grand university lecture hall, but during a stalled mining project in the Harz mountains. This piece, featuring the expertise of Dr. Lloyd Strickland, challenges the modern assumption that deep thought requires perfect conditions, arguing instead that the friction of a failed engineering venture sparked a revolution in how we understand reality itself.

The Paradox of the Perfect World

Matthias introduces the subject by highlighting a persistent confusion surrounding Gottfried Wilhelm Leibniz, a thinker often dismissed as obscure or contradictory. He leans heavily on the critique of Bertrand Russell to set the stage, writing, "[Leibniz] had a good philosophy which ... he kept to himself, and a bad philosophy which he published with a view to fame and money." This framing is crucial; it suggests that the Leibniz we know from textbooks is a carefully curated performance, while the true genius was hidden in private correspondence. Matthias notes that Leibniz "fell into Spinozism whenever he allowed himself to be logical," implying that the public version was a deliberate retreat from the terrifying implications of pure reason.

The article then pivots to the origin story of the Discourse on Metaphysics, a text written in a moment of forced idleness. Strickland, the guest author, explains that while Leibniz was trying to improve mine productivity with wind machines, he found himself with "nothing to do for a few days," leading him to write a "short discourse on metaphysics." Matthias emphasizes the irony here: a text that would define the relationship between God, substance, and the universe was drafted because a mining pump failed. This narrative choice effectively humanizes a figure often seen as coldly mathematical, grounding high abstraction in the mundane reality of a broken machine.

The core of Leibniz's argument, as presented, rests on the idea that God, defined as "an absolutely perfect being," must necessarily create the "best possible world." Matthias explains that this does not mean a world without suffering, but rather one that is "the simplest in terms of its underlying principles and the richest in terms of the variety of things it contains." This is a sophisticated defense of optimism that avoids naive denial of pain. However, critics might note that this definition of "best" can feel like a semantic sleight of hand to modern readers who struggle to reconcile systemic injustice with divine perfection. Yet, the argument holds weight when viewed through the lens of historical context; for Leibniz, the complexity of the world was a feature, not a bug, a necessary condition for a universe that maximizes existence.

A substance is not just a thing with properties, but something whose entire history is built into its very concept.

The Architecture of Reality

Moving beyond theology, the piece tackles the fundamental building blocks of reality. Matthias contrasts Leibniz with Descartes, noting that while Descartes saw bodies as defined merely by "extension, in other words by having size, shape, and motion," Leibniz demanded more. Strickland articulates Leibniz's radical claim that a true substance must possess a "complete concept," meaning that "everything that can ever be truly said about a thing is already contained within it." To illustrate this, the text uses the example of Alexander the Great, asserting that "all of Alexander's actions—his victories, his conversations, even the smallest details of his life—are contained in the concept of 'Alexander'."

This leads to the concept of pre-established harmony, where substances do not actually interact but merely appear to do so because God has synchronized their internal clocks. Matthias describes this as a divine coordination where "all substances mutually correspond with one another in such a way that their states agree." This is a profound shift from the mechanistic view of the universe as a collection of billiard balls colliding. Instead, the universe is a symphony where every instrument plays its part independently, yet perfectly in tune with the whole.

The article further explores Leibniz's reintroduction of "substantial form," a concept many of his contemporaries had discarded. Matthias argues that Leibniz found this necessary because purely extended matter lacks "unity and activity." He points out that Leibniz drew support from physics, showing that what is conserved in the universe is not just motion, but "force, which is closer to what we would now call energy." This is a brilliant synthesis of metaphysics and early physics, suggesting that the spiritual and the physical are not separate realms but different descriptions of the same underlying force. It is worth noting, however, that this reintroduction of scholastic concepts into a modern framework was highly controversial at the time and remains difficult for materialist philosophies to accept today.

Purpose in a Mechanical World

The final section of the commentary addresses the role of purpose, or "final causes," in nature. Matthias contrasts Leibniz with Descartes, who argued that we should ignore God's intentions and focus only on efficient causes. Leibniz, however, insisted that "when we see something that is good or orderly, we can reasonably say that it was intended." Matthias summarizes this by stating, "Nature, on this view, is not just a system of causes, but also a system of ends."

This perspective elevates the human mind to a special status within the "city of God," a community where minds are "active participants" striving toward the good. The text suggests that our ability to understand the world is not an accident but a reflection of our participation in the rational order of the universe. This is a powerful counter-argument to the modern tendency to view the universe as a meaningless machine. As Matthias puts it, Leibniz sets out a "vision of the world as ordered, intelligible, and purposeful, that he would spend the rest of his life refining."

The article concludes by reflecting on the nature of this discovery. Matthias writes, "It was not the product of a grand project or a systematic plan, but was written in a moment of pause." This framing serves as a gentle reminder to the busy reader that breakthroughs often come when we stop trying to force productivity and allow the mind to wander. The connection to the concept of the Monad, which Leibniz later developed as the ultimate simple substance, is implicit here; just as the Monad reflects the whole universe from its own perspective, this moment of idleness in the mountains reflected the whole of Leibniz's system.

Bottom Line

The strongest element of this piece is its ability to strip away the mystique of Leibniz's reputation and reveal the practical, almost accidental origins of his most enduring ideas. The argument that a failed mining project yielded a theory of pre-established harmony is a compelling narrative hook that makes dense metaphysics accessible. The biggest vulnerability lies in the sheer density of the concepts; without a prior grounding in 17th-century debates between rationalists and empiricists, the distinction between "extension" and "force" may feel abstract. However, for the reader willing to engage, the payoff is a renewed sense of the universe as a place of inherent order and purpose, a perspective that feels increasingly rare in our current age of fragmentation.

  • Monad (philosophy)

    The article hints at Leibniz's 'good philosophy' being hidden from the public; this concept is the core metaphysical unit of that private system, explaining how he reconciled individual freedom with a pre-ordained universe without resorting to the 'illogical' compromises of his published works.

  • Optimism

    While the excerpt lists 'the origin of evil' as a topic, this specific philosophical doctrine is the controversial conclusion Leibniz reached in the Discourse, arguing that our world is the 'best of all possible worlds'—a claim that directly stems from his attempt to logically solve the problem of sin mentioned in the text.

  • Principle of sufficient reason

    This specific logical axiom is the engine behind Leibniz's 'good philosophy' that Russell claims he suppressed, explaining why the author argues Leibniz had to be 'illogical' in his published works to avoid falling into Spinozism.

Dear friends of Daily Philosophy,

Welcome back to another fascinating article on the history of philosophy — and in this case about a thinker whom I personally always found impossible to understand: Leibniz. I don’t seem to be alone in my difficulties with the great man’s theories. Bertrand Russell writes:

“[Leibniz] had a good philosophy which... he kept to himself, and a bad philosophy which he published with a view to fame and money.... His bad philosophy was admired for its bad qualities, and his good philosophy, which was known only to the editors of his manuscripts, was regarded by them as worthless.... I think it is probable that as he grew older, he forgot the good philosophy, which he had kept to himself, and remembered only the vulgarized version by which he won the admiration of Princes and (even more) of Princesses.... Here, as elsewhere, Leibniz fell into Spinozism whenever he allowed himself to be logical; in his published works, accordingly, he took care to be illogical.” (Bertrand Russell, The Philosophy of Leibniz).

Thankfully, today’s guest author, Dr Lloyd Strickland, is one of those who understand Leibniz’s good philosophy better than almost anyone else, and he is going to give us an overview of its main themes.

Dr Strickland is particularly suited to be our guide to Leibniz’s works, because he is the author of a 3-volume edition of Leibniz’s Philosophical Papers, which will be published next week. You can get more information on the three volumes right here:

Vol.1: Universal Language, Characteristic, Logic, Encyclopaedia, and General Science.

Vol.2: Metaphysics, Natural Philosophy, Ethics, and Jurisprudence.

Vol.3: Religion and Theology.

Have fun reading and a great weekend! — Andy

A Philosophy Written in the Mountains.

Guest article by Lloyd Strickland

Not many seminal works of philosophy are the product of an unoccupied mind in the midst of a failed mining project, but that, it seems, was the story behind Leibniz’s Discourse on Metaphysics. At the beginning of January 1686, he travelled to the Harz mountains to continue his (ultimately ill-fated) project to improve the productivity of the mines there via wind machines and water pumps of his own invention. When the work stalled for a few days, Leibniz did what he did best: he thought. At the beginning of February 1686, he remarked to a friend that as he had nothing to do for a few days, he had “written ...
