Recommended to those who are eager to witness the pre-existing philosophical development that paves the way for the Chomskyan enterprise. Reading the selected excerpts from Von Humboldt, who posited that not only word formation or sentence formation is combinatorial but also the lexicon, or Herbert of Cherbury who advocated a highly naturalistic view of the mind, reveals how far backward mainstream 20th-century analytic philosophy has strayed.
Chomsky encompasses the significant romantic insight that emerged from Descartes, via James Harris, Schlegel, and Herder, namely that freedom lies in an untethering from stimulus and instinct. Thus, while beasts exist in states of affairs, men dwell among mental objects. (Referentialist/extensionalist semantics versus internal generativist semantics).
There is a crucial insight to be gained that human freedom is deeply intertwined with human knowledge.
There is also an important discussion regarding how PRG (presumably some philosophical or theoretical framework) motivated the distinction between the material of language and its impact on the soul. In modern terms, this is the difference between deep and surface structure.
Another significant insight unearthed from relative obscurity is the difference between organic and mechanical form (Schlegel, Coleridge). Mechanical form is externally imposed on an object, while organic form arises from the thing's own natural morphological development. Two important developments stem from this: In Developmental Biology, the ideas of Urform of Goethe and Gt. Geoffrey, where form determines function and which was cast aside during the Darwinian revolution, have been profoundly vindicated in the past half-century. The second is Marx's theory of alienated labor, which can now be simply summarized as the imposition of mechanical form on the worker instead of allowing the development of his own organic form in the production process.
Of course, none of this was worked out in detail. For instance, PRGians had no concrete hypothesis regarding the nature of deep structure. Goethe also could not explain how the urleaf could contain all possible variations of the leaf or how this was materially realized. Although one should not draw connections between Chomsky the linguist and Chomsky the political activist, he did not hesitate to quote the following line from Von Humboldt: "der Mensch überall Eins mit dem Menschen ist" (Man is everywhere one with man).
