While there is therefore much of interest in the general orientation that Garavaso and Vassallo pursue, my focus will be on Chaptersand the respects in which their exposition leaves their two main themes thinking and its epistemic significance underdeveloped.

If gednke are simply asked to consider what “two” means independently of the context of a sentence, we are likely to simply imagine the numeral “2”, or perhaps some conglomeration of two things. Names such as “Romulus” or “Odysseus”, and phrases such as “the least rapidly converging series” or “the present King of France” express senses, insofar as they lay out criteria that things would have to satisfy if they were to be the references of these expressions.

Previous logic had dealt with the logical constants andorif Frege suggests also that this confusion would have the absurd result that numbers simply are the numerals, the signs on the page, and that we should be able to study their properties with a microscope.

The Foundations of Frege’s Logic. Olms, ; reprinted in Thiel [] The Foundations of Arithmetic: And in exploring the epistemic significance of thinking, Garavaso and Vassallo promise to further illuminate of the rationalistic epistemological foundations of Frege’s logicist programme. However, we must bear in mind that the propositions: Sign In Forgot password?

However, this work seems to have been virtually ignored tedanke most of Frege’s contemporaries. Another heavy blow came after Frege’s death.

This presents a serious problem frete Frege’s logicist approach. Some of Frege’s most brilliant work came in providing definitions of the natural numbers in his logical language, and in proving some of their properties therein. As we shall see, he also made advances in the logic of mathematics. Mathematical truths are objective, not subjective. While Frege believed that logic might prescribe laws about how people should think, logic is not the science of how people do think.


It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide. In other projects Wikimedia Commons Wikiquote Wikisource. Frege concludes this because, although senses are obviously not physical entities, their existence likewise does not depend on any one person’s psychology.

Because the sense of a whole proposition is determined by the senses of the parts, and the reference of a whole proposition is determined by the parts, Frege claims that propositions in which such expressions appear are able to express thoughts, but are neither true nor false, because no references are determined for them. Frege was described by his students as a highly introverted person, seldom entering into dialogue, mostly facing the blackboard while lecturing though being witty and sometimes bitterly sarcastic.

His main argument against this view, however, was simply his own work in which he showed that truths about the nature of succession and sequence can be proven purely from the axioms of logic.

Therefore, two can be defined as the value-range of all value-ranges equal in size to the value-range of def concept being identical to zero or identical to one. Southern Illinois University Press, Logical truths would remain true even if no one believed egdanke nor used them in their reasoning. Oxford University Press is a department of the University of Oxford. On the notion of a value-range, see above.


Therefore, these expressions are meaningful, but do not have references.

Carnap attended these lectures and took notes. However, if “the morning star” means the same thing as “the evening star”, then the two statements themselves would also seem to have the same meaning, both involving a thing’s relation of identity to itself. Abbe gave lectures on theory of gravity, galvanism and electrodynamics, complex analysis theory of functions of a complex variable, applications of physics, selected divisions of mechanics, and mechanics of solids.

It suffices here to note that just as the same object e. It is not clear how Frege himself could count as thinking any mental activity which not only does not successfully grasp a thought, but which fregr even aim at one. Retrieved from ” https: Blackwell BenacerrafP. The distinction between levels of functions involves what kind of arguments the functions take.

As we shall see belowFrege was also committed to other gedaanke entities such as senses and thoughts.

Gottlob Frege (1848—1925)

Frege’s logical works were revolutionary, and are often taken to represent the fundamental break between contemporary approaches and the older, Aristotelian tradition.

We have seen how the notion of successorship can be defined for Frege, i. Russell had included an appendix on Frege in his Principles of Mathematics. Kluge in Kluge [] pp. An Ddr in the Philosophy of Mind. This sense picks out Aristotle the person because he alone matches this gedanie.

frete Verlag von Louis Nebert, marked a turning point in the history of logic. Kluge in McGuinness [] pp. In order to find a definition of numbers as objectsFrege treats them instead as value-ranges of value-ranges.
