As the overview article noted, debate over the “homeland” of Proto-Indo-European carries a history of dangerous political misuse. In his closing chapter, Anthony speaks candidly about why he believes his own method avoids repeating that mistake.

Imagination alone can’t tell history

A convincing narrative about the speakers of Proto-Indo-European must today be pegged to a vast array of archaeological facts, and it must remain un-contradicted by the facts that stand outside the chosen narrative path.

The metaphor of being “pegged” is striking. A narrative, on its own, is something like a piece of cloth — free to drift wherever the wind takes it. But peg that cloth down at many points — each peg being an individual archaeological fact — and it can no longer drift freely. The more pegs there are, and the more varied the kinds of pegs (dating methods, animal bones, artifacts, the distribution of vocabulary), the less likely the narrative is to be wrong.

Why this self-discipline was necessary

Just before this sentence, Anthony discusses the early-twentieth-century Aryan fantasy — a racist image of “the speakers of the mother tongue” constructed almost entirely out of linguistic speculation, with hardly any physical evidence behind it. At the time, there were almost no “pegs” available to restrain the imagination. Fragmentary linguistic evidence, romantic longing for classical antiquity, and the prejudices of social Darwinism piled on top of each other, and a convenient story could be built out of almost anything.

Anthony’s own position is a direct response to that failure. He presents the sheer mass of archaeological detail packed into his book — radiocarbon dates, statistics on animal bones, grave goods, settlement sizes — not as an apology for its density, but as evidence of methodological integrity.

A narrative with no pegs Built from imagination and guesswork No way to disprove it (e.g. the 20th-century Aryan fantasy) A narrative pegged to facts Dates, bones, artifacts, vocabulary Falsifiable by varied evidence If wrong, a peg eventually gives way The number and variety of pegs determines how trustworthy the narrative is

Falsifiability as a basic scientific stance

This passage is, in effect, a restatement, in archaeological language, of a basic idea from the philosophy of science: a claim only counts as scientific once it’s presented in a form that could, in principle, be shown wrong. What Anthony is conveying with the “pegged” metaphor isn’t a guarantee that his narrative is “correct” — it’s a guarantee that if it is wrong, someone will eventually be able to show it. That humility is exactly what separates Anthony’s own reconstruction from the Aryan fantasy built on imagination alone.

Summary

The quoteA convincing narrative must be pegged to a vast array of archaeological facts
The failure it answersThe early-twentieth-century Aryan fantasy — a narrative built on guesswork, with almost no pegs of physical evidence
The core stanceNot a guarantee of being “right,” but a guarantee of being falsifiable if wrong

In a nutshell — for Anthony, a good narrative wasn’t one told with a rich imagination, but one pegged down, with no room to drift, by the facts themselves.
