Abstract

The most important and extensive of Bernard Bolzano’s (1781–1848) correspondences is the one with his student and friend Michael Josef Fesl (1788–1864) which comprises altogether some 730 letters. Due to the great number of letters, starting with 1831, only Bolzano’s contributions are contained in his Collected Writings. Therefore, Fesl’s letters to Bolzano are published in the series "Beitraege zur Bolzano-Forschung". The present volume contains 88 letters that Fesl wrote in the years 1839 to 1841 to his “most-beloved teacher and friend”. They focus on the works published by Bolzano during those years as well as on several projects that could not be realized. Moreover, they deal with philosophical trends, theological questions and political problems as well as with the epidemics of that time and their various treatments (including their success). Finally, Fesl also discusses the qualities of three portraits of Bolzano’s created by Áron Pulzer, Heinrich Hollpein und Karl Hoffmann during those years.
