Gottlob Frege (1848—1925)

Translated as The Foundations of Arithmetic: The property of being the pupil of Plato and teacher of Alexander is unique to Aristotle, and thus, it may be in virtue of associating this information with the name “Aristotle” that this name may be used to refer to Aristotle. Beliefs depend for their make-up on how certain objects and concepts are presented, not only on the objects and concepts themselves. Rather, they target Dummett alone as ‘the foil against which we characterize our positions’, and ‘our main interlocutor in contrast to other more recent and not yet as influential scholars’ 8[1] and they explicitly bracket in particular 7 the growing array of historico-contextual investigations mentioned above.

Translated as “What is a Function? Therefore, these expressions are meaningful, but do not have references.

Frege also introduced an identity sign, standing for a function whose value is the True if the two arguments are gedannke same object, and the False otherwise, and a sign, which he called “the horizontal,” namely “—”, that stands for a function that has the True as value for the True as argument, and has the False gddanke value for any other argument. Let us consider the examples of 5 and 6 more closely. Frege concurred with Leibniz that natural language was unsuited to such a task.

We know for example that “the morning star” and “the evening star” have the same customary reference. Both of these expressions refer to the planet Venus, yet gedanje obviously denote Venus in virtue of different properties that it has. Take care that nothing gets lost. Frege’s logical ideas nevertheless spread through the writings of his student Rudolf Carnap — and other admirers, particularly Bertrand Russell and Ludwig Wittgenstein — Oxford Tedanke Press is a department of the University of Oxford.

For more on the distinction of levels of concepts, frfge above. It is clear that functions are to be understood as the references of incomplete expressions, but what of the senses of such expressions?

His book the Foundations of Arithmetic is the seminal text of the logicist project, and is cited by Michael Dummett as where to pinpoint the linguistic turn.

Lectures, Cambridge —, From the Notes of G. In Frege’s view, unlike objects, all functions are “unsaturated” insofar as they require arguments to yield values. To say that F is instantiated one time is to say there is an object x that instantiates Fand that for all objects yeither y does not instantiate F or y is x. Gottlob Frege — Gottlob Frege was a German logician, mathematician and philosopher who played a crucial role in the emergence of modern logic and analytic philosophy.


Feigl in Feigl and Sellars [] pp. Translated as Posthumous Writings. However, while the volume was already in the publication process, Frege received a letter from Bertrand Russell, informing him that it was possible to prove a contradiction in the logical system of the first volume of the G rundgesetzewhich included a naive calculus for classes.

Rather, it flanks terms for truth-values to form a term for a truth-value. In particular, they are functions mapping objects onto truth-values.

Views Read Edit View history. Where would he agree and where would he disagree? Frege’s suggestion is that “the number of F s” means the same as “the value-range of the concept being a value-range of a concept instantiated equally many times as F. Kluge in McGuinness [] pp.
