In 1817, in the preface to his Rein analytischer Beweis, Bernard Bolzano revealed that he had decided to postpone the publication of any subsequent instalment of his Beyträge zu einer begründeteren Darstellung der Mathematik because of the few and ‘superficial’ reviews of its first instalment, published in 1810. Bolzano’s transcriptions of the only two known reviews of this book are conserved at the Literární archiv Památníku národního písemnictví / Muzea literatury, in Prague, together with another manuscript on his Beyträge, the (...) provenance of which was unknown to Bolzano’s scholars until recently. In this paper it is shown that this latter manuscript is a draft of an announcement that was published at the time and that was indeed written at least to some extent by Bolzano himself. This hitherto unknown announcement of Bolzano’s Beyträge not only solves the mystery surrounding that manuscript, but also helps to date the publication of this book more precisely and provides an unusual insight into what we must take Bolzano himself to have considered most noteworthy about his work, namely his study on logic. The paper includes a transcription of the manuscript and an English translation of the announcement. (shrink)

The dissemination and reception of Bernard Bolzano's ideas were not only mediated by his personal circumstances and context but also by the vicissitudes of his work. This paper traces the fate of his works from his death in 1848 to the publication of the first volume of his Gesamtausgabe in 1969, and it does so with the help of one of the last published volumes of this edition, namely the Bolzano‐Gesamtbibliographie 1804–1999. As the paper shows, this book is more than (...) a mere list of publications and constitutes a highly valuable resource for anyone interested in Bolzano studies, the use of which is explained in detail.

Resumen: La concepción del ser humano como animal tecnológico, junto con la idea del progreso como sustento de la civilización, plantea varias cuestiones que precisan ser consideradas con detenimiento, entre ellas qué se entiende por progreso y qué sentido y valor tiene la tecnología. El caso de la realidad virtual patentiza de hecho la habitual asunción de la tecnología como algo ajeno a la producción cultural, humana. Sin embargo, la tecnología comparte nuestros límites y está sometida a nuestro designio, por (...) más que se le quiera asumir independiente de nosotros y por más que se intente reemplazar nuestra interacción con el espacio natural por una relación enteramente controlada en un medio virtual.: The idea of the human being as a technological animal, coupled with the idea of progress as the very foundation of civilization, raises several issues that need to be carefully considered, including the meaning of progress and the meaning and value of technology. The case of virtual reality indeed makes explicit the common assumption of technology as something alien to cultural, human production. However, technology shares our limits and it is subject to our plans, regardless of whether someone insists on assuming it independent of ourselves or insists on replacing our interaction with natural space by an interaction in an entirely controlled virtual environment.
