38 Lucretius De Rerum Natura Book VI (Diels 1923 Edition)

Titus Lucretius Carus’s De Rerum Natura remains the definitive intersection of Classical Philology, ancient physical theory, and the enduring human struggle against irrationality. As a foundational text for the Open Educational Resource (OER) community, it offers a window into how information transcends biological limits and historical epochs.

The “Meme” of Human Experience

The renowned naturalist David Attenborough, in discussing the 1515 Aldine edition of Lucretius, classifies such books as a vital category of “memes.” In his view, the book is a survival mechanism for the collective intellect, ensuring that wisdom is preserved outside the fallibility of the human body. Attenborough observes that:

“Human experience is embedded and handed down from generation to generation, outside the body… there’s 600 years of experience that’s hanging out there.”

For the OER architect, Lucretius is the ultimate “meme”—a curated packet of information that has survived the transition from 9th-century parchment to 16th-century print, and now to the digital commons, preserving ancient observations for the modern age.

Causal Connectedness and the Liberation of Mind

Albert Einstein, writing the foreword for the second volume of the Diels edition in 1924, noted the “magic” the poem works upon those not entirely submerged in the intellectual prejudices of their own time. Einstein was deeply moved by Lucretius’s commitment to an atomistic-mechanical worldview, seeing in it a precursor to modern scientific inquiry. Einstein writes:

“The firm confidence that Lucretius… places in the intelligibility, in other words, in the causal connectedness of everything that happens in the world, must make a profound impression.”

Einstein argues that Lucretius was guided by a psychological necessity: to persuade his readers of a mechanical reality in order to liberate them from a “slavish fear” of the supernatural. He further observes that Lucretius, out of an “altogether moving” reverence for the Greek culture of Epicurus, had to “dare not say this openly” to his “practically oriented Roman readers,” instead masking his radical physics in the “spirit of our age”—the high art of Latin hexameter.

2. Scholarly Context: The Hermann Diels 1923 Edition

The 1923 edition represents the pinnacle of early 20th-century philology. Hermann Diels, a dedicated “friend of Epicurean Philosophy,” died in 1922 before the work reached its final form. It was subsequently edited and published by Johannes Mewaldt.

Quick Reference

• Primary Editor: Hermann Diels (1848–1922).
• Posthumous Editor: Johannes Mewaldt (1880–1964).
• Publication History: Volume 1 (Latin Text & Praefatio), 1923; Volume 2 (German Translation & Einstein Foreword), 1924.
• Manuscript Foundation: Diels relies heavily on the Schedae Vindobonenses (U), essential 9th-century (nono saeculo) fragments that offer critical corrections to the primary manuscript tradition for the latter half of Book VI.

The Diels edition is prized by philologists for maintaining the “colorful and powerful art of writing” characteristic of Lucretius, while the Praefatio provides an architect’s view of how the indices capitum (table of contents) were intended to guide Epicurean disciples through complex natural phenomena.

This roadmap organizes the text of Book VI according to the line ranges found in the 9th-century Schedae Vindobonenses (U) as described in the 1923 Diels preface.

4. Synthesis: From Atomism to the Plague of Athens

The progression of Book VI represents the ultimate trial of the “atomistic-mechanical worldview.” By moving from the vast, celestial scale of meteorological phenomena down to the microscopic, terrestrial arrival of the Plague, Lucretius demonstrates what Einstein termed “causal connectedness.”

• Rhetorical Strategy: Lucretius acknowledges that his “practically oriented Roman readers” might find pure physics abstract. He therefore concludes with the visceral reality of the Plague of Athens to prove that science has a “liberating effect.”
• The Ethical End of Physics: The transition from the physics of magnetism to the clinical description of disease is intended to strip away “slavish fear.” Even in the midst of the most horrific human tragedy, Lucretius asserts that the universe remains a single, intelligible system governed by the regular motion of immutable atoms.

Final Takeaways for OER Learners

• Atomism as Framework: Scientific inquiry serves a moral purpose: the psychological liberation of the individual.
• Reverence for the Source: Lucretius’s “altogether moving” dedication to Greek wisdom (Epicurus) demonstrates how OER principles of sharing and building upon previous knowledge are ancient traditions.
• The Survival of the Meme: As Attenborough suggests, the text is a 600-year-old (and counting) mechanism for the survival of human wisdom across the “electronic age.”
