Chapter One traces the 19th century development of a new way of thinking about language structure, and about systematicity more generally, in the work of German linguists like Jacob Grimm, Franz Bopp, and their successors. It argues that this new perspective grows out of a widespread backlash, prepared and supported by Friedrich Schelling’s “nature-philosophy,” against the Kantian understanding of system. The most significant German scientists of the period presuppose, as Kant does not, the extra-human reality of the orders they analyze, and thus also the extra-human reality of analyzable structure per se. In the realm of Idealist philosophy, the result is a new theory of History, writ cosmically large. In the realm of language science, the result is a newly rigorous etymological methodology, designed to render writeable the laws of empirical language change, and by doing so, to articulate the essence of a teleologically-unfolding “language spirit” or Sprachgeist.
