Freidenker / Statuten des Freidenker / Enthüllungen aus der geistlichen Welt / Offener Brief an den katholischen Klerus... / Luzifer. Eine Bombe der Wahrheit...

This binding from Osijek presents an extremely interesting and almost complete collection of works by Michael Biron, the organizer of the first free-thinking (Freidenker) movement in Austria. The binding is not just a collection of unrelated publications, but a logically complex whole that shows the development of his movement from organizational beginnings through public propaganda to open conflict with the Catholic Church and his persecution from Austria.

• Freidenker. Blätter für Humanität, Aufklärung und Bildung (issues 1–30, 1869–1871) The first and largest part of the binding (480 pages) consists of all thirty issues of the journal Freidenker, the official newsletter of the Freidenker Society in Graz. The magazine was the movement's central means of communication and at the same time its intellectual platform. Biron started it in 1869 with the aim of promoting humanity, education, freedom of conscience and critical thinking

The last issues are particularly valuable because they document the growing pressures to which Biron was exposed. They increasingly mention legal proceedings, attacks by opponents and the need for solidarity among members. The closing letter in issue 30 shows that the author feels isolated, but still believes in the continuation of the movement's work.

• Statuten des Freidenker-Vereines in Graz (1869) The magazine is followed by the society's statutes, a kind of constitution of the organization. Today it is particularly interesting because it shows how moderate and legalistic the movement was in the beginning. The very first article states that the purpose of the society, "leaving politics aside", is to work for humanity, enlightenment and education.

The organization was democratically organized, and members could be both men and women, which was quite advanced for 1869. The last page states that the statutes were officially approved by the Regency in Graz on October 22, 1869, confirming that the society was not initially banned or illegal.

• Offener Brief an den katholischen Klerus und an alle Katholiken (Open Letter to the Catholic Clergy and All Catholics) - seventh edition, circa 1870. This pamphlet represents Biron's public reckoning with the institution to which he once belonged. The work is important because it shows the transition from organizational work to open public criticism of the Church.

• Enthüllungen aus der geistlichen Welt (Revelations from the Clergy World) - Graz 1870, third edition. This book is probably Biron's most personal work. The title does not refer to the "spiritual world" in the mystical sense, but to the world of the clergy and church institutions.

The work has the characteristics of a memoir, a confession, and a social critique. It was precisely this combination that appealed to readers because it did not come from an external opponent of the Church, but from a man who had long been part of the system he was now describing.

• Lucifer. Eine Bombe der Wahrheit in das römische Concil oder Vertheidigung der Religion des reinen Menschenthums (Lucifer. A Bomb of Truth in the Roman Council or the Defense of the Religion of Pure Humanity) - Graz, Leykam 1870, 46 pp.; in the copy up to p. 40, the last 6 pages are missing. The last work in the collection represents the culmination of Biron's ideological struggle. It was written at the time of the First Vatican Council (1869–1870), when the dogma of papal infallibility was proclaimed.

The title is deliberately provocative. Biron uses the name Lucifer in its original meaning of light-bearer and transforms it into a symbol of reason, knowledge, and free inquiry. He contrasts it with the blind acceptance of authority and dogma. The central idea of ​​the book is the defense of the religion of pure humanity, that is, the belief that moral life can exist without church institutions and supernatural revelations.

In contrast to the moderate tone of the society's statutes, Lucifer is a distinctly polemical and combative work. It is in it that we can most clearly see why Biron became one of the most controversial figures of the Austrian freethinking movement.

Viewed as a whole, this volume presents almost the entire intellectual biography of Michael Biron between 1869 and 1871:

• the journal depicts the daily life and development of the movement,

• the statutes show its organizational program,

• the open letter represents a public break with the Church,

• Revelations from the Priestly World bring the personal testimony of a former priest,

• Lucifer presents his most elaborate philosophical and worldview position.

This Osijek copy can therefore be seen as a small library of Austrian freethinking from the turn of the 1860s into the 1870s. It is unlikely that such a content was bound by chance; it is much more likely that it was compiled by some dedicated subscriber or sympathizer of the Freidenker movement who wanted to preserve the entirety of Biron's work in one volume.
