Alexander von Humboldt: Perceiving the World provides an interdisciplinary exploration into Humboldt’s approach to seeing and describing the many subjects he pursued. Though remembered primarily as an environmental thinker, Humboldt’s interests were vast and documented not just in his published works, but also in his extensive correspondence with scientists, artists, poets, and philosophers internationally. Perceiving the World covers Humboldt’s perceptions during intercontinental travels and scientific discoveries, as well as how he visualized nature, geography, environments, and diverse cultures, including Indigenous Peoples.This collection draws heavily on the English translations of Humboldt’s work housed in the Purdue University Archives, which were collected by John Purdue. The book is divided into three parts: Humboldt’s contributions to science since the nineteenth century; his work on nature, climates, environments, and the cosmos; and his lasting cultural impact, including his imaging techniques, modes of visual presentation, and contributions to the arts. Humboldt’s intricate approach to perception still resonates today, as his nuanced and unique way of seeing the world was just as important as what he wrote.
