 Claims of objectuality are not to be confused with claims of actuality (§142). Though, for example, Bolzano maintained that there are (es gibt) propositions and ideas in themselves, as well as geometrical points and other mathematical objects, he denied at the same time that they had actual existence (i.e., they do not act, or enter into causal relations, no spatial or temporal determinations attach to them, etc.). The ideas [proposition in itself], [geometrical point], etc., that is, have objectuality but propositions, points, etc., lack the property of actuality.
