Single Idea 22276

[filed under theme 19. Language / D. Propositions / 1. Propositions ]

Full Idea

Bolzano took the entities of which truth is predicated to be not propositions in the subjective sense but 'propositions-in-themselves' - objective entities existing independent of our apprehension.

Gist of Idea

Bolzano saw propositions as objective entities, existing independently of us

A Reaction

A serious mistake. Presumably the objective propositions are all true (or there would be endless infinities of them). So what is assessed in the case of error? Something other than the objective propositions! We assess these other things!
