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)

Kant's views on logic and logical theory play an important role in his critical writings, especially the Critique of Pure Reason. However, since he published only one short essay on the subject, we must turn to the texts derived from his logic lectures to understand his views. The present volume includes three previously untranslated transcripts of Kant's logic lectures: the Blumberg Logic from the 1770s; the Vienna Logic (supplemented by the recently discovered Hechsel Logic) from the early 1780s; and the (...) Dohna-Wundlacken Logic from the early 1790s. Also included is a new translation of the Jasche Logic, compiled at Kant's request and published in 1800 but which also appears to stem in part from a transcript of his lectures. Together these texts provide a rich source of evidence for Kant's evolving views on logic, on the relations between logic and other disciplines, and on a variety of topics (e.g. analysis and synthesis) central to Kant's mature philosophy. They also provide a portrait of Kant as lecturer, a role in which he was both popular and influential. This volume contains substantial editorial apparatus: a general introduction, linguistic and factual notes, glossaries of key terms (both German/English and English/German) and concordances relating Kant's lectures to Georg Frederich Meier's Excerpts from the Doctrine of Reason, the book on which Kant lectured throughout his life and in which he left extensive notes.

Let me start with a well-known story. Kant held that logic and conceptual analysis alone cannot account for our knowledge of arithmetic: “however we might turn and twist our concepts, we could never, by the mere analysis of them, and without the aid of intuition, discover what is the sum [7+5]” (KrV, B16). Frege took himself to have shown that Kant was wrong about this. According to Frege’s logicist thesis, every arithmetical concept can be defined in purely logical terms, and (...) every theorem of arithmetic can be proved using only the basic laws of logic. Hence, Kant was wrong to think that our grasp of arithmetical concepts and our knowledge of arithmetical truth depend on an extralogical source—the pure intuition of time (Frege 1884, §89, §109). Arithmetic, properly understood, is just a part of logic. (shrink)

ABSTRACT This paper seeks to clarify Husserl’s critical remarks about Kant’s view of logic by comparing their respective views of logic. In his Formal and Transcendental Logic Husserl criticizes Kant for not asking transcendental questions about formal logic, but rather ascribing an ‘extraordinary apriority’ to it. He thinks the reason for Kant’s uncritical attitude to logic lies in Kant’s view of logic as directed toward the subjective, instead of being concerned with a ‘“world” of ideal Objects’. Whereas for Kant, general (...) logic is about laws of reasoning. Husserl thinks that formal logic should describe formal structures. Husserl claims that if Kant had had a more comprehensive concept of logic, he would have thought of raising critical questions about how logic is possible. This kind of criticism cannot itself use forms of judgments or syllogisms of logic, nor even the ‘inferential’ [schliessende] method more generally, but should be descriptive in nature. Husserl's transcendental phenomenology is the method for such criticism. The paper argues that this results in reflection, and possibly revision, of the logical principles with respect to the normative goals governing the investigation in question. (shrink)

This is an intelligent and useful collection of works by Husserl. The editors have assembled twenty-one short works; some appeared first as essays, some are manuscripts, some are letters, some are extracts from larger works. Most important, they cover a wide range of topics and thus make up a rather colorful collection. Five are brief "introductions" to phenomenology: Husserl's inaugural lecture at Freiburg ; his introduction to the English edition of Ideas ; his Encyclopedia Britannica article ; his summary of (...) his London lectures ; and his summary of the Paris lectures. Another group is made up of papers concerning logic and mathematics: an early essay on the concept of number ; the very important essay "Psychological Studies for Elementary Logic" which contains some of the central ideas later found in Logical Investigations; a critique of psychologism entitled "On the Psychological Grounding of Logic" ; and a book review in which Husserl responds to a critic of the Logical Investigations. The issue of phenomenology as a science is developed in two works, the essay "Philosophy as Rigorous Science", in which Husserl criticized Dilthey; and an ensuing exchange of three letters between Dilthey and Husserl. Perhaps the most interesting part of the volume is made up of a series of studies of space and time. Two are manuscript essays ; one is "The Origin of Geometry" ; one is a selection from the lectures on internal time consciousness ; and one is a selection from Experience and Judgment which deals with inner time, perception, imagination, and association. The last section contains three general "humanistic" papers by Husserl, "Phenomenology and Anthropology" ; a paper on cultural and moral renewal ; and one on universal teleology which deals with sexuality. There is also a recollection Husserl wrote of Franz Brentano, letters to Munsterberg and Metzger, and short pieces on Eucken, Reinach, and George Bernard Shaw. (shrink)

The objective of the present work is to develop a theory of meaning based on the method of transcendental phenomenology. The key idea of the project is to explain the constitution of the meaning by means of the analyses of the intentionality. We have investigated different intentional acts which are functioning in the expression and in constructing the meanings. In this regard we have studied, first, the act of the primordial expression, in which a content of an intuition is raised (...) to the realm of the ideal, and then the acts of the categorial synthesis, in which further meanings are constituted in the absence of their proper intuition. -/- We have investigated the effects of the phenomenological theory of meaning to the conception of pure logic. Dialogical semantics is shown to be an adequate framework, from the phenomenological point of view, to interpret logical reasoning and to explain the meaning of the logical constants as well. -/- We have also discussed the meanings of some logical connectives, and their formalizations, using our phenomenologico-dialogical method. In particular, the meaning explanations of negation(s), strict implication and necessity are given in a way which is not model theoretic nor proof theoretic, but based on the transcendental intentionality as manifested in the course of the dialogue.

This entirely new English translation of Buridan's classic treatment of logical consequence aims to make accessible to the modern reader the foremost treatment of the subject in the middle ages. The translation is accompanied by an introduction in which Buridan's ideas are set in their historical context and clearly explained.

This volume tackles Gödel's two-stage project of first using Husserl's transcendental phenomenology to reconstruct and develop Leibniz' monadology, and then founding classical mathematics on the metaphysics thus obtained. The author analyses the historical and systematic aspects of that project, and then evaluates it, with an emphasis on the second stage.

This volume includes three previously untranslated transcripts of Kant's logic lectures.

Burt C. Hopkins presents the first in-depth study of the work of Edmund Husserl and Jacob Klein on the philosophical foundations of the logic of modern symbolic mathematics. Accounts of the philosophical origins of formalized concepts—especially mathematical concepts and the process of mathematical abstraction that generates them—have been paramount to the development of phenomenology. Both Husserl and Klein independently concluded that it is impossible to separate the historical origin of the thought that generates the basic concepts of mathematics from their (...) philosophical meanings. Hopkins explores how Husserl and Klein arrived at their conclusion and its philosophical implications for the modern project of formalizing all knowledge. (shrink)

Husserl repeatedly has claimed that (1) mathematics without a philosophical foundation is not a science but a mere technique; (2) philosophical considerations may lead to the rejection of parts of mathematical practice; but (3) they cannot lead to mathematical innovations. My thesis is that Husserl's third claim is wrong, by his own standards.
