Better than its first volume, "The Science of Freedom" is part of the late historian Peter Gay's quest to provide a foundation for late twentieth century secular progressivism. Now profoundly challenged by contemporary historians, Gay's book retains some value for its wide-ranging interpretation of eighteenth century art, philosophy, and society, as well as its extensive bibliography (fairly authoritative on early twentieth century works on the philosophes). Yet, Gay's triumphalist narrative is no longer in vogue; indeed, now very much doubt has been cast upon his and Ira Wade's approach, 'updated' to become Jonathan Israel's "modernization thesis," where the West slowly marches toward greater freedom, enlightenment, and peace as it gradually sloughs off the superstitions of Judaism and Christianity. What we see in the eighteenth century can actually be interpreted as a "religious enlightenment" (Sorkin), or, as a series of several "enlightenments" taking place all across Europe and the "new world" in a variety of ways. When the idea is dispersed this broadly, though, one might interrogate the very notion of "enlightenment" in the first place.
The very word, enlightenment, involves a metaphor, and every metaphor involves the imagination - an imagination nourished by culture, tradition, and religion. In short, it makes a metaphysical claim. What was once dark, ignorant, obscured is now brightened, known, and clarified. This process or procedure is "Enlightenment." According to the philosophes, this happens through education coupled with the freedom of expression and publication, along with a popularization of the new discoveries of natural philosophy (science). What Hamann saw, and few others did, is that with a secular "Enlightenment," new priests are called for with new rituals, new authoritative books, and new creeds. What was once explained quite clearly by philosophers like Aquinas and Cusanus, as, for example, the meaning and scope of human reason, is now explained (or failed to be explained) in a thousand contradictory ways by different self-proclaimed philosophes - the "free-thinkers." From this plethora of interpretations, there is a mass fragmentation of ideas about everything from God to nature. The so-called Romantics try to pick up the pieces and re-weave the rainbow (Keats), but without success. Blake saw this, as did thinkers such as Von Baader, but with God increasingly vague and nebulous and 'pantheized,' art unravels from life and becomes a religion unto itself: "art for art's sake" (Pater). With a brief gasp for mysticism and tradition (Symbolism), our philosophies then degenerate into surreal fantasies and nihilistic modernism. From these mid-twentieth century nightmares, the surrender to simulation (where art and language and art and life form a puzzling, never-ending circle, like a snake eating its own tail) that is postmodernism dies an ignominious death and no one is sad.
Now the time is ripe for a continuation and intensification - across confessional lines - of the ressourcement of the twentieth century, where the "Enlightenment" is seen through the lens of the Orthodox Philokalia (published in 1782), for example, or the blank verse poem "Night Thoughts" (1742-45) by Edward Young. We also have the grievously overlooked dialogues of James Hervey (d. 1758), the profound writings of J. G. Hamann (d. 1788), and the theological-philosophical poems of Chris. Smart and Wm. Blake. Rather than there being a 'counter-enlightenment' (Isaiah Berlin) which is opposed to the rationalism and free-thinking of the "Enlightenment," we will realize that in every era there is barbarism and cruelty, irrationalism and hatred - in every epoch man is repeating the sin of the original garden; the only true enlightenment is from the light that is above (φῶς ἄνωθεν), the light that is given, not by Kantian gatekeepers, but by the Spirit.
