Reflections on Poetry: Alexander Gottlieb Baumgarten’s Meditationes philosophicae de nonnullis ad poema pertinentibus makes newly accessible the 1735 dissertation that inaugurated the modern discipline of aesthetics. Long remembered chiefly as the inventor of the term, Baumgarten here sets out the principles of a “science of sensate cognition,” laying philosophical foundations for poetry and the arts alongside logic and metaphysics. Through a rigorously deductive method, he defines poetry as “perfected sensate discourse,” analyzing its clarity, vividness, and order with the same systematic care his rationalist contemporaries brought to science. Drawing heavily on Horace’s Ars poetica, Baumgarten transforms scattered critical insights into an axiomatic poetics that gives the arts a rightful place within philosophy.

The volume presents both the Latin text and an English translation, supported by commentary that clarifies Baumgarten’s method, his departures from Cartesian rationalism, and his pioneering claim for aesthetics as an autonomous field. It highlights how Baumgarten’s rationalist framework led him to emphasize extensive clarity, the role of imagery and wonder, the importance of thematic unity, and the analogy between poetic creation and natural process. More than a historical curiosity, the Reflections reminds us that art can be understood as a mode of cognition, balancing the clarity of reason with the richness of perception. The enduring takeaway is that Baumgarten’s “charter of modern aesthetics” still speaks to contemporary debates, challenging us to think of poetry—and art more broadly—not merely as expression of emotion but as a disciplined pursuit of perceptual perfection and meaning.
