through final causes leads to the distinction between what. That principle, as understood in the Grundlagen, ought therefore not to be invoked as underpinning realism, but as dismissing the issue as spurious. As we have seen, a sign such as " H ( is a sign for a function in the strictest sense, as are the conditional and negation connectives. Frege introduces the distinction between sense and reference by the example of proper names. Frege's logical works were revolutionary, and are often taken to represent the fundamental break between contemporary approaches and the older, Aristotelian tradition. Sometime after the publication of the. After his military service, he studied at Christ Church College, Oxford, graduating with First Class Honours in Philosophy, Politics and Economics in 1950 and then attained a fellowship at All Souls College. And it is for this reason that Leibniz will claim that all of nature is full of life ( Principles of Nature and Grace 1: G VI 598/AG 207) and that there are infinite degrees of life in the monads.

In mathematics, an equation such as " f ( x ) x 2 1" states that f is a function that takes x as argument and yields as value the result of multiplying x by itself and adding one. Thus, while " H ( b ) H ( a is simply a term for a truth-value, " H ( b ) H ( a asserts that this truth-value is the True, or in this case, that if Boston is human, then Aristotle is human. Indeed, Frege's "firsts" in logic are almost too numerous to list. This has lead to a very important debate in the philosophy of language, which, unfortunately, we cannot fully discuss here. Perhaps his most important contributions to the philosophy of mathematics were his arguments for this view.

But, ultimately, the picture is even more complex than this, for each of the subordinate monads can be considered as having an organic machine attached to it, and this relation continues on to the infinitely small. Let us consider the examples of (5) and (6) more closely. Therefore, Frege introduces a sign he called the "judgment stroke, used to assert that what follows it stands for the True. The former is a product, the latter a difference, etc. Dummett holds that there are two guiding principles that we need in order to understand Frege's work on sense and reference. These expressions are incomplete in the sense that they contain an "empty space which, when filled, yields either a complex name referring to an object, or a complete proposition. According to Dummett, Frege's unsuccessful project had two important by-products. The connection between a semantic theory and a meaning-theory should now be apparent. Leibniz will use this seemingly innocuous principle to draw profoundly strong metaphysical conclusions about the nature of substance and modality.
