Canonical propositions this source was matched as evidence for.
How Hirsch uses it
Every occurrence, grouped by book and chapter, with the claim it was linked to support and (where the extraction regenerated one) the underlying warrant.
1977 · The Philosophy of Composition
The failed prediction of Henry Sweet regarding the mutual unintelligibility of English, American, and Australian speakers after a century.
direct Henry Sweet's 1877 prediction that English dialects would become mutually unintelligible by 1977 proved false.
Warrant (implicit): The persistence of mutual intelligibility between geographically separated populations over a specified timeframe invalidates previous scientific theories predicting divergent linguistic evolution.
could fail ifThe rise of global mass media and telecommunications created a stabilizing feedback loop that Sweet could not have anticipated in 1877.
1987 · Cultural Literacy
Henry Sweet's 1870s prediction that British, Australian, and American English would become mutually incomprehensible within 100 years.
direct Linguist Henry Sweet predicted that the English language would eventually split into mutually unintelligible dialects.
Warrant (implicit): The consensus of the most prominent experts in a field at a given historical moment constitutes a reliable baseline for what would have occurred under natural conditions.
could fail ifExpert consensus can be biased by the prevailing theoretical paradigms of the time, such as 19th-century social Darwinism, which may have overestimated natural divergence.
Historical prediction by Henry Sweet that English would diverge into mutually unintelligible dialects within a century.
direct Linguist Henry Sweet predicted that the English language would eventually split into mutually unintelligible dialects.
Warrant (implicit): Long-term predictions made by recognized authorities reflect the expected trajectory of a system in the absence of a significant intervening variable.
could fail ifThe failure of a prediction might be due to the expert's initial misunderstanding of linguistic mechanics rather than the presence of an intervening social force like education.
2022 · American Ethnicity
Henry Sweet's 1877 prediction that English, Australian, and American speech would become mutually incomprehensible within 100 years.
direct Modern linguists like Sapir and Bloomfield incorrectly prioritized oral language and the 'law of constant change' while underestimating the stabilizing power of literacy.
Warrant (explicit): Predictions of linguistic divergence based on oral evolution are invalidated by the counter-force of mass literacy which preserves a common standard.
could fail ifThe expert predictions may have been based on insufficient data regarding the speed of dialect formation rather than an ignorance of literacy.
