Oxford University Press, 25— Frege is generally credited with identifying the following puzzle about propositional attitude reports, even though he didn’t quite describe the puzzle in the terms used below.

By contrast, in the modern predicate calculus, this last step of analyzing predication in terms of functions is not assumed; predication is seen as more fundamental than functional application.

Philosophers only recently appreciated the importance of this work C. Olms contains the English version of Frege [] AustinJ. Frege’s Life and Influences 2. See May b for a nice discussion of the question of whether Frege believed that the sense of a name varies from person to person.

Each of these expressions has both a sense and a denotation. Sources were checked, errors were eliminated, and page numbers were added whenever possible. Wissenschaftliche Buchgesellschaft and Hildesheim: He suggested that existence is not a concept under which objects fall but rather a second-level concept under which first-level concepts fall.

But E maps e to The True if and only if e is an extension which is not an element of itself, i. Creative definitions fail to be conservative, as this was explained above. Begriffsschrift, eine der arithmetischen nachgebildete Formelsprache des reinen DenkensHalle a.

This means it allows quantification over functions as well as quantification over objects; i. In traditional Aristotelian logic, the subject of a sentence and the direct object of a verb are not on bgeriffsschrift logical par.

But Frege noticed that this account of truth can’t be all there is to the meaning of identity statements. To see this more clearly, here are the formal representations of the above informal arguments:. The extension of the concept spoon is not an element of itself, because that concept would map its own extension to The False since extensions aren’t spoons.

But both Bolzano and Frege saw such appeals to intuition as potentially introducing logical gaps into proofs. His logic is based on functional application rather than predication; so, a binary relation is analyzed as a binary function that maps a pair of arguments to a truth-value.

His philosophy of language has had just as much, if not more, impact than his contributions to logic and mathematics. Frege declared nine of his propositions to be axiomsand justified them by arguing informally that, given their intended meanings, they express self-evident truths. To explain these puzzles, Frege suggested a that in addition to having a denotation, names and descriptions also express a sense. Interestingly, one section of the thesis begriffsscbrift the representation of complex numbers by magnitudes of angles in the plane.

Despite the fact that a contradiction invalidated a part of his system, the intricate theoretical web of definitions and proofs developed in the Grundgesetze nevertheless offered philosophical logicians an intriguing conceptual framework.

Though the discussion will involve the notion of an extension, we shall not require Basic Law V; thus, we can use our informal understanding of the notion. While pursuing his investigations into mathematics and logic and quite possibly, in order to ground those investigationsFrege was led to develop a philosophy of language.

begriffsschrict As MacFarlane points out, one of Kant’s most central views about logic is that its axioms and theorems are purely formal in nature, i. Mirror Sites View this site from another server: There is a reply in defense of Hilbert by A. Since the object of arithmetic does not have an intuitive character, its fundamental propositions cannot stem from intuition… Fregetranslation in McGuinness ed.

Nevertheless, his definitions e. Why aren’t we still saying something true about the man in question if all we have done is changed the name by which we refer to him?

White in Hermes et al. This course of Frege’s reading and lectures during the period of — dovetailed quite naturally with the interests he displayed in his Habilitationsschrift. One final important difference between Frege’s conception of logic and Kant’s concerns the question of whether logic has any content unique to itself. From Wikipedia, the free encyclopedia.
