Frege’s Theory of Judgment.

Frege, Gottlob | Internet Encyclopedia of Philosophy

For Frege, the distinction applies also to other sorts of expressions and even whole sentences or propositions. Gottlob Frege was a German logician, mathematician and philosopher who played a crucial role in the emergence of modern logic and analytic philosophy.

Kripke points out that this would make a claim such as “Aristotle taught Alexander” seem to be a necessary and analytic truth, which it does not appear to be. Since all and only those things that have hearts have kidneys, strictly speaking, the concepts denoted by the expressions ” has a heart”, and ” has a kidney” are one and the same.

As Frege understands this, it means that if ggedanke expressions have the same reference, they should be able to replace each other within any proposition without changing the truth-value of gedane proposition.

Review of Philosophie der Arithmetikby Edmund Husserl. After laying out the basic laws of logic, and defining axioms governing the truth-functions and value-ranges, etc.

Here, care must be taken to avoid misunderstanding. Here they focus on ffrege fact that, for Frege, thinking is an act which serves as a general precondition for any act of knowing any truths, since grasping a thought is a general precondition to knowing its truth. This page was last edited on 21 Decemberat Logical truths would remain true even if no one believed them nor used them in their reasoning.

In the late s and early s Frege developed new and interesting theories regarding the nature of language, functions and concepts, and philosophical logic, including a novel theory of meaning based on the distinction between sense and reference. In giving examples, Frege implies that a person might attach to the name “Aristotle” the sense the pupil of Plato and teacher of Alexander the Great.

This idea was formulated in non-symbolic terms in his The Foundations of Arithmetic In such cases, the expressions are said to have their secondary references. Frege argues that Thoughts may be expressed without thereby being asserted: Essays in Honor of Henry M.

Olms, ; reprinted in Thiel []frefe Corrigenda six pages and some textual criticism. Marcus, ; reprinted Darmstadt: For example, if we consider the propositions: Moreover, he claims that many of us seem to be able to use a name to refer to an individual even if we are unaware of any grdanke uniquely held by that individual.

Frege also introduced an identity sign, standing for a function whose value is the True if the two arguments are the same object, and the False otherwise, and a sign, which he called “the horizontal,” namely “—”, that stands for a function that has the True freege value for the True as argument, and has the False as value for any other argument. Macmillan DudmanV. Gexanke citations to Frege’s letters are compiled. Unfortunately, Garavaso and Vassallo engage very little with either set of discussions.

He also argued against the Kantian view that arithmetic truths are based on the pure intuition of the succession of time. Frege Gottlob and Hilbert David. Thomae’s Theories of Irrational Numbers. Email required Address never made public. Philosophical Library SalmonN. Walter de Gruyter, Frege rejects this view for a number of reasons.

In this short book, Pieranna Garavaso and Nicla Vassallo aim to re-focus discussions of Frege toward two neglected aspects of his work: Let me turn now to Garavaso and Vassallo’s treatment of Frege’s conception of the epistemic significance of thinking Chapter 4. For example, many of us don’t know enough about the physicist Richard Feynman to be able to identify a property differentiating him from other prominent physicists such as Murray Gell-Mann, but we still seem to be able to refer to Feynman with gedahke name “Feynman”.

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.

It is from this that Frege came be to be a bit wider known, including to an Austrian student studying engineering in Manchester, England, named Ludwig Wittgenstein.

It involves the theory of complex mathematical functions, gedaanke contains seeds of Frege’s advances in logic and the philosophy of mathematics.

Translated as Posthumous Writings. In the case of concepts, their value-ranges were identified with their extensions. Frege could then use mathematical induction to prove some of the basic laws of the natural numbers.

Both were also principals of the school at various points: While Frege believed that logic might prescribe laws about how people should think, logic is not the science of how people do think. A logico-mathematical enquiry into the concept of number Complete translation by J.

One could then consider numbers as “second-level concepts”, or concepts of concepts, which can be defined in purely logical terms.
