In 1433, Nicholas proposed reform of the Holy Roman Empire and a method to elect Holy Roman Emperors. Although it was not adopted by the Church, his method was essentially the same one known today as the Borda count, which is used in many academic institutions, competitions, and even some political jurisdictions, in original form and a number of variations. His proposal preceded Borda's work by over three centuries.
Nicholas' opinions on the Empire, which he hoped to reform and strengthen, were cited against papal claims of temporal power in the sixteenth and seventeenth centuries. Protestants writers were happy to cite a cardinal against Rome's pretensions. Protestants, however, found his writings against the Hussites wrong. Nicholas seemed to give the church too much power to interpret Scripture, instead of treating it as self interpreting and self-sufficient for salvation, the principle of sola scriptura.
It's not often enough I come upon someone that did so much that I had never heard about. Scott Horton is expanding my education into so many fields with his blog I can't praise it enough.

When I learn of men like Casanus I get both joy and am empowered.
