This volume is a window on a period of rich and illuminating philosophical activity that has been rendered generally inaccessible by the supposed "revolution" attributed to "Analytic Philosophy" so-called. Careful exposition and critique is given to every serious alternative account of number and number relations available at the time.

In arithmetic, if only because many of its methods and concepts originated in India, it has been the tradition to reason less strictly than in geometry, ...

In tracing the formation of Husserl's concept of constitution, we hope to further the understanding of what he considers a philosophical explanation. ...

This book grew out of a graduate student paper [261] in which I set down some criticisms of J. R. Lucas' attempt to refute mechanism by means of G6del's theorem. I had made several such abortive attempts myself and had become familiar with their pitfalls, and especially with the double edged nature of incompleteness arguments. My original idea was to model the refutation of mechanism on the almost universally accepted G6delian refutation of Hilbert's formalism, but I kept getting stuck on (...) questions of mathematical philosophy which I found myself having to beg. A thorough study of the foundational works of Hilbert and Bernays finally convinced me that I had all too naively and uncritically bought this refutation of formalism. I did indeed discover points of surprisingly close contact between formalism and mechanism, but also that it was possible to under mine certain strong arguments against these positions precisely by invok ing G6del's and related work. I also began to realize that the Church Turing thesis itself is the principal bastion protecting mechanism, and that G6del's work was perhaps the best thing that ever happened to both mechanism and formalism. I pushed these lines of argument in my dis sertation with the patient help of my readers, Raymond Nelson and Howard Stein. I would especially like to thank the latter for many valuable criticisms of my dissertation as well as some helpful suggestions for reor ganizing it in the direction of the present book. (shrink)

Husserls »Logische Untersuchungen« sind eines der folgenreichsten Werke der neueren Philosophiegeschichte. Mit dem ersten Erscheinen in den Jahren 1900 und 1901 (Max Niemeyer Verlag, Halle/Saale) nimmt jene Schule ihren Anfang, deren Name im Untertitel des zweiten Bandes zum ersten Mal sinnfällig wird: die Phänomenologie. Husserl sah damals in diesem Werk »Versuche zur Neubegründung der reinen Logik und Erkenntnistheorie«, die den Grund zu einem größeren Gedankengebäude zu legen imstande waren. Sie wollten freilich kein bloßes Programm sein, sondern »Fundamentalarbeit an den unmittelbar (...) erschauten und ergriffenen Sachen« darstellen. Die weitere Arbeit an der Ausprägung der phänomenologischen Philosophie führte schon nach wenigen Jahren zu neuen Problemen, zu vertieften Erkenntnissen und zu schärferen Formulierungen. Ihnen trägt die zweite, zum Teil tiefgreifend umgearbeitete Auflage Rechnung, deren Text seither in unveränderter Form immer wieder nachgedruckt wurde. (shrink)

This massive two-volume reference presents a comprehensive selection of the most important works on the foundations of mathematics. While the volumes include important forerunners like Berkeley, MacLaurin, and D'Alembert, as well as such followers as Hilbert and Bourbaki, their emphasis is on the mathematical and philosophical developments of the nineteenth century. Besides reproducing reliable English translations of classics works by Bolzano, Riemann, Hamilton, Dedekind, and Poincare, William Ewald also includes selections from Gauss, Cantor, Kronecker, and Zermelo, all translated here for (...) the first time.

INTRODUCTION In the first part of this study I will deal with the publications of Husserl's first period, ie Ueber den Begriff der Zahl (his "Habilita- ...

Der Begriff der Zahl ist ein vielfacher. Darauf weist uns schon die Mehrheit verschiedener Zahlworter hin, die in der Sprache des gewohnlichen Lebens auftreten und von den Grammatikern unter 5 folgenden Titeln aufgefiihrt zu werden pflegen: die Anzahlen oder Grundzahlen (numeralia cardinalia), die Ordnungszahlen (n. ordinalia), die Gattungszahlen (n. specialia), die Wiederho­ lungszahlen (n. iterativa), die Vervielfaltigungszahlen (n. multi­ plicativa) und die Bruchzahlen (n. partitiva). DaB die Anzahlen 10 als die ersten in dieser Reihe genannt werden, beruht ebenso wie die (...) charakteristischen N amen, die sie sonst tragen - Grund- oder Kardinalzahlen -, nicht auf bloBer Konvention. Sie nehmen sprachlich eine bevorzugte SteHung dadurch ein, daB die samt­ lichen iibrigen Zahlworter nur durch geringe Modifikationen aus 15 den Anzahlwortern hervorgehen (z. B. zwei, zweiter, zweierlei, zweifach, zweimal, zweitel). Die letzteren sind also wahrhafte Grundzahlworter. Die Sprache leitet uns hiermit auf den Gedan­ ken hin, es mochten auch die korrespondierenden Beg r iff e samtlich in einem analogen Abhangigkeitsverhaltnisse stehen 20 zu denen der Anzahlen und gewisse inhaltsreichere Gedanken vor­ steHen, in welchen die Anzahlen bloBe Bestandteile bilden. Die einfachste Uberlegung scheint dies zu bestatigen. So handelt es sich bei den Gattungszahlen (einerlei, zweierlei usw. ) um eine Anzahl von Verschiedenheiten innerhalb einer Gattung; bei den Wieder- 25 holungszahlen (einmal, zweimal usw. ) um die Anzahl einer Wiederholung. Bei den Vervielfaltigungs- und Bruchzahlen dient die Anzahl dazu, das Verhaltnis eines in gleiche Teile geteilten Ganzen zu einem Teile bzw. (shrink)

While many books have been written about Bertrand Russell's philosophy and some on his logic, I. Grattan-Guinness has written the first comprehensive history of the mathematical background, content, and impact of the mathematical logic and philosophy of mathematics that Russell developed with A. N. Whitehead in their Principia mathematica (1910-1913).? This definitive history of a critical period in mathematics includes detailed accounts of the two principal influences upon Russell around 1900: the set theory of Cantor and the mathematical logic of (...) Peano and his followers. Substantial surveys are provided of many related topics and figures of the late nineteenth century: the foundations of mathematical analysis under Weierstrass; the creation of algebraic logic by De Morgan, Boole, Peirce, Schröder, and Jevons; the contributions of Dedekind and Frege; the phenomenology of Husserl; and the proof theory of Hilbert. The many-sided story of the reception is recorded up to 1940, including the rise of logic in Poland and the impact on Vienna Circle philosophers Carnap and Gödel. A strong American theme runs though the story, beginning with the mathematician E. H. Moore and the philosopher Josiah Royce, and stretching through the emergence of Church and Quine, and the 1930s immigration of Carnap and GödeI. Grattan-Guinness draws on around fifty manuscript collections, including the Russell Archives, as well as many original reviews. The bibliography comprises around 1,900 items, bringing to light a wealth of primary materials. Written for mathematicians, logicians, historians, and philosophers--especially those interested in the historical interaction between these disciplines--this authoritative account tells an important story from its most neglected point of view. Whitehead and Russell hoped to show that (much of) mathematics was expressible within their logic; they failed in various ways, but no definitive alternative position emerged then or since. (shrink)
