Willumsen began by tracing the historical evolution of European copyright architecture.
In the medieval Christian world, knowledge was treated as a divine gift rather than private real estate. Creators did not "own" their texts, nor could they commodify knowledge itself. The cultural priority was preservation and lineage, not individual novelty. Consequently, copying, quoting, and direct imitation were standard, legitimate methodologies of knowledge production.
It was not until the eighteenth century, fueled by the printing press and the emergence of a commercial literary market, that the "author" solidified as a legal subject. Willumsen noted that modern copyright law was originally engineered to incentivize cultural production and regulate market circulation. "Originality" was commodified as an asset requiring state protection, while imitation was relegated to mechanical, uncreative repetition.
This shift relied heavily on John Locke’s property theory: ownership over an object is established solely through the application of an individual's "labor." This philosophical framework became the foundational bedrock of modern intellectual property regimes.
Yet Brecht always kept his distance from this "myth of originality."
To him, writing was never creation from thin air. Quoting, rewriting, collage, translation, and reuse were simply the norm in creative work. He even invented the fictional character "Herr Keuner," weaving Chinese philosophy, Zhuangzi's thought, and a wealth of quotations directly into the text.
Willumsen noted that Brecht thought theater bears resemblance to science, in the sense that not every line needed to be patented. In one manuscript, he even wrote: "Theater doesn't need patented details."
