A quote from this review of Peter Murphy and David Roberts Dialectic of Romanticism by Robert Savage in Colloquy:

The dialectics of enlightenment and romanticism were both triggered by the historicist self-understanding of modernity, with its chronic awareness of man's pre- or deformation through cultural factors over which he has no immediate control. Together,Together, enlightenment and romanticism makeup the divided unity of [European] modernism ... Whereas enlightenment rationalism has as its goal the liberation of man from the contingencies of birth and custom, romanticism responds by calling for a return to nature. Regardless of how such a return may be construed in individual cases as the descent to the chthonian realm of the Earth Mother (Bachofen, Baeumler), as the remembrance of nature in the subject (Horkheimer/Adorno), as the repetitive recuperation of the original event of Being(Heidegger) the split between nature and spirit is in each case to be overcome through their reunion in a new mythology founded upon the free interplay of the rational and creative faculties.

Savage says that Murphy and Roberts maintain that this project:

...leads to consequences as invidious as those it was intended to counteract: Enlightenment autonomy is always threatened by the immanent contradiction of denaturalization: the reversal of freedom into unfreedom (the perpetuation of the blindnessof nature); romantic incarnation is always threatened by the immanent contradiction of renaturalization: the reversal of the spiritualization of natureinto the naturalization of spirit, of creative into destructive nature. Each bears witness to the failed internal dialogue of modernity.
