Frege’s Philosophy of Language While pursuing his investigations into mathematics and logic and quite possibly, in order to ground those investigationsFrege was led to develop a philosophy of begriff.

To ground his views about the relationship of logic and mathematics, Frege conceived a comprehensive philosophy of language that many philosophers still find insightful.

Creative definitions fail to be conservative, as this was explained above. Since the object of arithmetic funktiln not have an intuitive character, its fundamental propositions cannot stem from intuition… Fregetranslation in McGuinness ed.

This is quite unobjectionable, especially since its earlier intuitive character was at bottom mere appearance.

Now the problem becomes clear: Then Frege was the first to suggest that proper definitions have to be both eliminable a definendum must always be replaceable by its definiens in any formula in which the former occurs and conservative a definition should not make it possible to prove new relationships among formulas that were formerly unprovable.
