چکیده
“By properties which are asserted of a concept I naturally do not mean the characteristics which make up the concept. These latter are properties of the things which fall under the concept, not of the concept. Thus “rectangular” is not a property of the concept “rectangular triangle”; but the proposition that there exists no rectangular equilateral rectilinear triangle does state a property of the concept “rectangular equilateral rectilinear triangle”, it assigns to it the number naught. In this respect existence is analogous to number [in being a second-level concept]. Affirmation of existence is in fact nothing but denial of the number naught. Because existence is a property of concepts the ontological argument for the existence of God breaks down.” (“Foundations of Arithmetic”)

In such cases, it, we say that x is good because x is so and so – where x is so and so is not itself an explicitly evaluative claim, requiring still further defense. If T1 is correct, this natural id...

متن کاملSeminar 7: the Logic of Principia Mathematica
Volume 1 of Principia Mathematica, in which Russell and Whitehead set out their reduction of arithmetic to logic was published in 1910. Although the reduction adopts a conception of number very much like Frege’s, it is developed in a system of logic designed to avoid the paradox that defeated Frege. Avoiding it required giving up the idea that for every formula in the logical language, there is...
