Of Latitudes Unknown is a multi-faceted study of James Baldwin's radical imagination. It is a selective and thoughtful survey that re-investigates the grounds of Baldwin studies and provides new critical approaches, subjects, and orientations for Baldwin criticism. This volume joins recent critical collections in “un-fragmenting” Baldwin and establishing further conjunctions in his work: the essay and the novel; the polemical and the aesthetic; his use of and participation in visual forms; and his American as well as international identities. But it goes beyond other recent studies by focusing on new entities of Baldwin's radical imagination: his English and French language selves; his late encounters with Africa; his appearances on French television and interviews with French journalists; and his unrecognized literary journalism. Of Latitudes Unknown also addresses Baldwin's relations with the Arab world, his anticipation of contemporary film and media studies, and his paradoxical public intellectualism. As it reassesses Baldwin's contributions to and influences on world literary history, Of Latitudes Unknown equally explores why the critical appreciation of Baldwin's writing continues to flourish, and why it remains a vast territory whose parts lie open to much deeper exploration and elaboration.

From Hipparchus and Ptolemy in the ancient world, through Copernicus and Brahe in the sixteenth century, astronomers had used geometrical models to give a kinematic account of the movements of the sun, moon, and planets. Johannes Kepler revolutionized this most ancient of sciences by being the first to understand astronomy as a part of physics. By closely and clearly analyzing the texts of Kepler's great astronomical works, in particular the Astronomia nova of 1609, Bruce Stephenson demonstrates the importance of Kepler's physical principles--principles now known to be "incorrect"--in the creation of his first two laws of planetary motion.
