Brugmann’s thinking doesn’t stop at the single textbook this feature has read. Two threads run through it: what he inherited from Bopp and Schleicher, and what was directly challenged in his own time.

What he inherited from Bopp and Schleicher

As another article showed, Brugmann positioned his own method as “roughly a middle course” between Bopp’s flowing whole and Schleicher’s orderly individual grammars. But style of presentation wasn’t the only thing he set out to move past. As the Schleicher feature on this site showed, Schleicher treated language as a natural organism in the literal sense, explaining its change as a natural process cut off from human will. Brugmann’s generation kept its distance from that idea itself. Sound law and analogy, in their view, were phenomena arising strictly from the process of human speakers using language and passing it on to the next generation — not a biological process, cut off from humans, like an oak tree growing naturally.

Just a year before publication — Schuchardt’s challenge

Just a year before Volume I of Brugmann’s Grundriss appeared in 1886 — in 1885 — the Austrian linguist Hugo Schuchardt published a provocative pamphlet titled Über die Lautgesetze: Gegen die Junggrammatiker (On Sound Laws: Against the Neogrammarians). Schuchardt directly questioned the Neogrammarian principle that “sound laws operate without exception,” arguing that language change is far messier than that, shot through with social factors — contact between speakers, the mixing of dialects, individual variation.

In other words, at exactly the moment Brugmann was quietly setting down his conviction, in this book’s preface, that “every exception has a reason,” the very foundation of that conviction was already under open attack from a contemporary scholar.

Distance from Müller, proximity to Jespersen

Worth placing alongside the figures already covered in this feature set. The Max Müller feature on this site covered lectures aimed largely at bringing linguistics to a general audience — a rather different orientation from the Neogrammarians’ strict focus on sound law. Closer in time is Otto Jespersen, covered elsewhere on this site. Jespersen belonged to a generation slightly younger than Brugmann’s, and while he built on the Neogrammarian framework of sound law and analogy, he extended it further — into the psychology of speakers and the analysis of actual speech acts. The attitude Brugmann opened up — that every exception has a reason — was carried forward into the next generation, reshaped along the way.

Summary

ConnectionDetail
From Bopp and SchleicherInherited the merits of their presentation styles, while distancing himself from “language as a natural process”
Conflict with SchuchardtJust a year before publication, an open rebuttal had already challenged exceptionless sound law itself
To JespersenThe framework of sound law and analogy was carried forward, and extended toward the psychology of speakers

In a nutshell — Brugmann’s conviction that “every exception has a reason” was never universally shared, even in his own time. This textbook entered the world standing right next to an open rebuttal from a contemporary scholar.
