Bolzano, Bernard. 1996. "Contributions to a Better-Grounded Presentation of Mathematics (1810)." In From Kant to Hilbert: A Source Book
in the Foundations of Mathematics. Vol. I, edited by Ewald, William, 174-224. Oxford: Clarendon Press.
Translation by Steve Russ, (abbreviated: BD) revised reprint in The Mathematical Works of Bernard Bolzano, pp. 87-137.
"The work BD must be one of the first books devoted to what we would now call foundations of mathematics, or philosophy of
mathematics. (Indeed, this latter phrase was the title given to it by Fels for the second edition.) After a short Preface the first main part is devoted to the
nature of mathematics and its proper classification. The second part deals with definitions, axioms, proofs, and theorems. It is here that the
ground-consequence relation is introduced:
in the realm of truth . . . a certain objective connection prevails . . . . some of these judgements are the grounds of others and the latter
are the consequences of the former. (BD II § 2)
He goes on to explain that the proper purpose to pursue in a scientific exposition is to arrange the judgements so as to reflect this
objective connection. (p. 21-22)
An important contribution Bolzano makes here is a solution to the problem of how to define, or come to agreement, on the basic or simple
concepts of a system. He says we should do so in the same way as we first learn terms in our mother tongue by considering several propositions containing the
term (see BD II § 8). This is akin to what we would call implicit definition and, of course, is closely related to axiomatic systems. However, this is
hindsight; there is no suggestion that Bolzano did, or could, consider axiom systems with the degree of formality familiar since the work of Hilbert.
Any such book as BD could hardly ignore Kant and his thinking aboutmathematics and accordingly there is an Appendix devoted to a criticism of
Kant's theory of the construction of mathematical concepts through pure intuition. The central point of Bolzano's criticism was that the very notion of pure
intuition was incoherent containing, he believed, internal contradictions. An excellent account of this, and indeed the whole methodology outlined in
BD, is contained in Rusnock Bolzano's Philosophy and the Emergence of Modern Mathematics (2000), Ch. 2. For a more extended and philosophical
discussion of Bolzano's views of proof and their relationship to Kant see Lapointe (forthcoming) [Bolzano's Semantics and his Criticism of the
Decompositional Conception of Analysis" in The Analytic Turn, Michael Beaney (Ed.), London, Routledge, 2007, pp. 219-234].

"During the earliest stages of my work on this translation, I enjoyed the co-operation and advice of my teacher, the late Henry S. Leonard. A
preliminary draft of the first volume was finished in 1958, but at that time I was still thinking of a complete translation of all four volumes. I was
eventually persuaded that early complaints about the unnecessary bulk of the work had their point. Kambartel's very successful attempt at shortening the first
two volumes (Bernard Bolzano's Grundlegung der Logik, Hamburg, 1963) finally convinced me that an abbreviated version was not only feasible, but
desirable." (p. VII).

"The present selection from the Wissenschaftslehre of Bernard Bolzano aims at giving a compact view of his main ideas in logic,
semantics, epistemology and the methodology of science. These ideas are analyzed from a modern point of view in the Introduction. Furthermore, excerpts from
Bolzano's correspondence are included which yield important remarks on his own work.
The translation of the sections from the Wissenschaftslehre are based on a German text, which I have located in the Manuscript
Department of the University Library in Prague (signature: 75 B 459). It was one of Bolzano's own copies of his printed work and contains a vast number of
corrections made by Bolzano himself, thus representing the final stage of his thought, which has gone unnoticed in previous editions." (from the Preface).

Translated from the German of the posthumous edition by Franz Prihonský and furnished with a historical introduction by Donald A. Steele.

"The Paradoxien are the work of Bolzano's old age. Indeed, the modern mathematical reader who takes the text as it stands will be
occasionally disappointed, and may misjudge Bolzano if he has not also read his earlier work. The qualification of taking the text 'as it stands' is not
otiose. Our received version, here translated from the 1851 Leipzig edition, is a posthumous one by a friend with whom Bolzano discussed the topics in question
for the last few years of his life. The competence of Prihosnky, as an editor of mathematical matter and the trustworthiness of the received version of the
Paradoxien have recently been placed in doubt by Martin Jasek, the discoverer of the counter-example.
The antecedents of the Paradoxien go back at least as far as 9 June 1842, when Bolzano read 'that part of his paper on the march of
ideas to be followed in a truly scientific exposition of mathematics which deals with the finite and infinite.' The next traces are three instalments of papers
read as follows: on 9 January 1845 about 'a solution of sundry paradoxes occurring in the mathematical sciences' ; on to December 1846 about 'calculations with
infinite numerical expressions'; and on 24 February 1848 about 'the paradoxes occasioned in mathematics by the idea of the infinite.' The gradual
crystallisation of the eventual title is manifest. Between the first and second paper, on 3 February 1845, Bolzano wrote to Prihonsky that he was busy with
sundry paradoxes in mathematics; between the second and third, he wrote twice to Fesl: on 26 February 1848 that he now realised more than ever the importance
of the topics of the Paradoxien for mathematics and its philosophy, and on 24 June 1848 that the matter for the Paradoxien is constantly
expanding under his pen. Finally, on 30 November 1848, only eighteen days before his death, Bolzano read a final instalment under the final title of
Paradoxien des Unendlichen.
Unlike the manuscript of the Funktionenlehre, that of the Paradoxien was never made ready for the press by the author
himself. That task fell to his devoted but none too mathematical friend Prihonsky. In fact, Bolzano himself had entertained doubts about the posthumous
treatment of his mathematical papers, for he wrote to Fesl as early as 12 June 1842 that he was convinced 'that his mathematical ideas, in their present form,
could not be really well edited by any of his friends.' This premonition on Bolzano's part comes to corroborate the suspicions of Jasek.
Those suspicions were aroused by a palpable contradiction between the Funktionenlehre and the Paradoxien.
The received text of §37, pages 65-66, as distinguished from the footnote, makes no actual assertion as to the universal existence of
derivates of continuous functions; Bolzano simply intends to choose such as are differentiable for a certain purpose: ' Ich begehre nichts anderes, als
dass.' But a footnote says it can be shown that 'all well defined functions' are bound to be differentiable 'save possibly for a set of arguments which
may indeed be infinite, but whose members must be individually isolated.' No proof is attempted. Jasek ('Aus dem handschriften Nachlass Bernhard Bolzanos',
Vestnik Kralovske Ceske Spolecnosti Nau, Trida matematicko-prirodovedeckd (1923), pp. 29-32) claims to possess evidence that the footnote is
interpolated. He suspects Slivka von Slivitz, another pupil and friend of Bolzano, of being Prihonsky necessary but not sufficient mathematical counsellor, and
of having timorously desired to shield Bolzano from the appearance of mathematical heresy which his counterexample may well have borne to contemporaries.
A fresh critical study of the manuscript is indicated, and external obstacles stand in the way for the present. The difficulty does not,
however, reside solely in the passage noticed by Jasek. It recurs in §45, page 88. Strictly speaking, again, there is even here no actual assertion that all
continuous functions are differentiable, and the question is further complicated by the admitted fact that the posthumous editor found the manuscript in places
rather illegible, in spite of his acquaintance with Bolzano's peculiar abbreviation practices. The presumption of guilt on the part of von Slivitz is slightly
enhanced, in Jasek's eyes, by a study of his marginal annotations to a copy of the Funktionenlehre. With baffling contrariety, it is also slightly
alleviated by the fact that the Zusammensetzung der Krafte, published in 1842 by Bolzano himself -- and embodying with acknowledgement some
suggestions by von Slivitz -- proceeds (§52, page 29) to differentiate a function of which only the continuity is known, together with its satisfaction of
conditions which are not quoted as if they established the otherwise uncertain differentiability. The hypothesis that Bolzano's mathematical discrimination had
become dulled between 1830 and 1848 on this point at least is simple and not to be rejected a priori; but neither is it to be accepted easily until
renewed and exact archivial research compels us to do so." (pp. 53-55).

"The main goal of this volume is to present a representative selection of the mathematical work and thought of Bolzano to those who read
English much better than they could read the original German sources. It is my hope that the publication of these translations may encourage potential research
students, and supervisors, to see that there are numerous significant and interesting research problems, issues, and themes in the work of Bolzano and his
contemporaries that would reward further study. Such research would be no small undertaking.
Bolzano's thoughtwas all of a piece and to understand his mathematical achievements properly it is necessary to study his work on logic and
philosophy, as well as, to some extent, on theology and ethics. Of course, it would also be necessary to acquire the linguistic, historical, and technical
skills fit for the purpose. But the period of Bolzano's work is one of the most exciting periods in the history of Europe, from intellectual, political, and
cultural points of view. And with over half of the projected 120 volumes of Bolzano's complete works (BGA) available, the resources for such research
have never been better. Thework on mathematics and logic has been particularly well-served through the volumes already published." (p. XII).

"It is clear that Bolzano was not satisfied with the logic set out in the Contributions . Already in 1812 he had resolved to
write another treatise on logic,(4) a project he worked on for close to a decade following his dismissal. The result was one of the great works of
nineteenth-century philosophy, the Theory of Science.(5) The Theory of Science was ready for the press by 1830, at which time Bolzano started
writing the Theory of Magnitudes [Grossenlehre], a treatise intended to supply a unified foundation for all of contemporary mathematics.(6)
Although he wrote several hundred pages, many of them all but ready for the press, but died before finishing his work. Some elements of his mathematical system
were published after his death in the Paradoxes of the Infinite,(7) edited by his friend and student F. Prihonsky, but the bulk remained all but
unknown until well into the twentieth century. The essay "On the Mathematical Method", translated here, formed part of the introductory matter of the
Theory of Magnitudes, and was intended to present the essentials of Bolzano's logic to a mathematical audience.
Due in large part to his troubles with the Austrian authorities, the Theory of Science remained unpublished for almost a decade (it
was finally published outside Austria, in Bavaria, in 1837). This did not mean, however, that Bolzano's logic remained unknown. Long accustomed to an invasive
and often arbitrary censorship, Bohemian intellectuals had developed unofficial channels for communicating their ideas, a precursor of the Samizdat
system which was later to flourish in that land. Bolzano's mature logic received its first airing in this way, when, in 1833, he had a copy made of the essay
on mathematical method and sent it to Franz Exner, the newly appointed professor of philosophy in Prague.(8)
Exner (1802-1853) was born and educated in Vienna, where he studied philosophy with Rembold, who like Bolzano (and for similar political
reasons) had been removed from his university chair in 1825. In 1830, Exner was put in the uncomfortable position of taking his teacher's place, being called
upon to fill the vacant chair on a temporary basis. In 1832 he moved to Prague, where he was named to the chair of philosophy. Outside of his official duties,
in good Austrian fashion, he organized a "circle" of intellectuals which met regularly at his house. Although a born and bred Viennese, he was sensitive to the
special circumstances of Bohemia, particularly to the disadvantaged situation of the Czech majority. Politically, though not always philosophically, he was
very much on Bolzano's side: with the Bohemian enlightenment and opposed to the conservative reaction in both church and state. Exner was a follower of
Herbart, who had a substantial following in Austria at the time, and whose doctrines were to become in effect the official philosophy of the Empire, in part
due to Exner's influence when he worked for the Ministry of Education from 1845 until his death.(9)
Exner responded to Bolzano in June of 1833, beginning a correspondence that would continue for the rest of Bolzano's life. The most intense
philosophical exchanges occurred during 1833 and 1834, when the letters translated here were written. The two continued their discussion in person in 1834,
when Bolzano returned to Prague from June to November. There would also be a later exchange of views in a pair of papers read at the Royal Bohemian Academy of
Sciences in the early 1840s. We have translated Bolzano's contribution, which contains the relevant passages from Exner's, in this volume." (pp. 6-8)

139-168), was actually published somewhat earlier (1831).

"In his own day, few appreciated Bolzano's contributions to theoretical philosophy and mathematics: only a small number were even
aware that he had done this work. He was renowned. rather, for his work as "catechist". professor of religious science (Religionswissenschaft) at the
Charles University in Prague from 1805 to 1819. In this highly visible position, Bolzano had become one of the most prominent advocates of social justice and
reform in his homeland, a national philosopher who was the "social and political conscience of Bohemia" (4)

"A unique philosophical dialogue
The present volume contains an altogether remarkable document in the history of nineteenth-century philosophy: a critical commentary on he
most influential systematic work (the Critique of Pure Reason) of one major philosopher (Kant), written from the point of view of another major
systematic philosopher (Bolzano), just decades after the former's publication. Bolzano, at the height of his powers, and with his mature philosophical views
having fully taken shape with the publication of his Theory of Science (1837), undertakes the project of engaging, key point by key point, with Kant's
masterwork. In collaboration with Bolzano, Frantisek Prihonsky (who would ultimately publish the final record of this work in 1850, shortly after Bolzano's
death) both compiles a comprehensive and thorough summary of the main definitions, theses, and arguments in Kant's book, and then proceeds to bring to light
the most important unclarities, confusions, and fallacies that he finds each step along the way. The result, New Anti-Kant, is not only an extremely
useful and even-handed overview of the entire first Critique itself - including parts often neglected by even Kant's most sympathetic readers - but
also a catalogue of philosophically insightful and textually well-grounded challenges to signature Kantian doctrines. This work helps us to see anew the
overarching contours of Kant’s philosophy, and brings a fresh focus onto deep points of tension within Kant's system - all the while serving to introduce us,
through instructive contrast, to the powerful alternative perspective that Bolzano develops in his own systematic philosophy." (pp. 3-4).
