THE EXISTENTIAL QUANTIFIER AND THE PROBLEM OF THE PREDICATION OF EXISTENCE IN BOLZANO
Languages of publication
Instead of the existential quantifier Bernard Bolzano uses his notion of 'Gegenständlichkeit einer Vorstellung an sich' (objectivity of a representation in itself). This approach makes it possible for him to solve the traditional problem of the predication of existence (i.e. whether it is possible to consider existence as a standard property of individuals) in accordance with an approach common today, namely to take existence to be primarily a property ('occupation') of a corresponding representation in itself, and not a characteristic of individuals. However, Bolzano considers a property of real existence to be attributable also to particular individuals, which is essentially different from the usual practice.
