Kepler was one of the most important sources of inspiration for Leibniz. The influence of Kepler can be detected in numerous features of Leibniz’s planetary theory as well as in other aspects of his thought:

Kepler’s Influence on Leibniz’s Planetary Theory

In Chapter I of The History of Scepticism from Erasmus to Spinoza, Richard Popkin offers a succinct and accurate account of the dispute over the basis of religious knowledge that was a central quarrel of the Reformation. The idea is this: In Luther’s initial criticism of Catholic practices he accepted the Catholic position that religious propositions are to be tested for truth by their agreement with Church tradition, councils, and Papal pronouncement. But in subsequent writings Luther took the decisive step of recommending replacement of the Catholic criterion by a test phrased in terms of consistency with Scripture, as interpreted by the conscience of the faithful. Popkin went on to note that Calvin transformed this simple test into an elaborate epistemology of religious knowledge without thereby denying Luther’s basic claims. Popkin then traced the history of the alliance between Catholic Counter Reformation thinkers and sixteenth and seventeenth century Pyrrhonian sceptics, in their efforts to undermine Calvin’s epistemology of religious knowledge. In Chapter VI Popkin noted the Jansenists uses of Catholic Pyrrhonism in defense of their antiphilosophical views and their opposition to rational theology. And in his seminal paper “Scepticism, Theology, and the Scientific Revolution in the Seventeenth Century,”1 Popkin clarified the ways in which the new sciences and traditional theology interfaced in the seventeenth century.
