A committed Lutheran excommunicated from his own church, a friend to Catholics and Calvinists alike, a layman who called himself a “priest of God,” a Copernican in a world where Ptolemy still reigned, a man who argued at the same time for the superiority of one truth and the need for many truths to coexist—German astronomer Johannes Kepler was, to say the least, a complicated figure. With The Pursuit of Harmony, Aviva Rothman offers a new view of him and his achievements, one that presents them as a story of Kepler’s attempts to bring different, even opposing ideas and circumstances into harmony.
Harmony, Rothman shows, was both the intellectual bedrock for and the primary goal of Kepler’s disparate endeavors. But it was also an elusive goal amid the deteriorating conditions of his world, as the political order crumbled and religious war raged. In the face of that devastation, Kepler’s hopes for his theories changed: whereas he had originally looked for a unifying approach to truth, he began instead to emphasize harmony as the peaceful coexistence of different views, one that could be fueled by the fundamentally nonpartisan discipline of mathematics.

This paper evaluates Kepler's 1618–1621 Epitome of Copernican Astronomy in light of two contextual events: the 1616 Decree of the Index banning Copernican books (including Volume 1 of Kepler's Epitome in 1619) and the start of the Thirty Years' War in 1618. Kepler's Epitome seems to defy traditional genre expectations: it takes the form of a text-book, and yet (especially in later volumes) it is more complicated than a traditional university primer, and seems targeted toward more expert readers. I argue that Kepler deliberately reframed the Epitome and modified its focus and approach in the years between the publication of its first volume in 1618 and its later volumes in 1620 and1621. These changes were related to Kepler's attempt to circumvent the ban on the first volume and help the book reach readers in Italy. To Kepler, a lifelong advocate for the Copernican cause, it was imperative that his book reach as many readers as possible. The spread of his work would both help educate potential future Copernicans and aid in overturning the ban on Copernican publication itself. Further, Kepler believed that princely readers might use the book's arguments as a model for peace in a time of war.
