This capacious course of lectures binds a philosophy of life to a philosophy of language, claiming that vitality is the formative principle of nature, history, and art, and that speech is life's luminescent organ. Ranging from myth to etymology and comparative grammar, Schlegel traces how languages grow, differentiate, and embody national spirit while mediating thought. The lectures move with Romantic breadth-at once aphoristic and systematic-synthesizing philology and cultural history. Set within late German Romanticism and conversing with Herder, Humboldt, and post-Kantian Naturphilosophie, the book proposes an organic alternative to mechanistic models of mind and society. Friedrich von Schlegel, cofounder of early Romanticism, was both critic and philologist; his study of Sanskrit and Indo-European roots, together with a turn to Catholic universality, oriented him toward historical development and unity in diversity. In his later Vienna lectures he sought to reconcile speculative philosophy with empirical scholarship, fusing the salon wit and fragmentary daring of Jena with mature systematic ambition. For readers of philosophy, literary theory, theology, and linguistics, this book offers a generative map of ideas. It rewards anyone seeking to grasp how words shape worlds and how cultures live through their languages, an indispensable entry to Romantic thought's living legacy.
