Single Idea 15571

[filed under theme 5. Theory of Logic / C. Ontology of Logic / 2. Platonism in Logic ]

Full Idea

The whole idea of an atemporal realm of validity is an invention that is no less doubtful than medieval speculation about angels.

Gist of Idea

The idea of an atemporal realm of validity is as implausible as medieval theology

Source

A Reaction

This seems to be flatly opposed to the view of Frege, and shows why continental philosophy has largely eschewed a study of logic. It is hard for a philosopher to pursue logic extensively without commitment to the Fregean Third Realm.


The 5 ideas with the same theme [that logical entities have independent existence]:

Frege thinks there is an independent logical order of the truths, which we must try to discover [Frege, by Hart,WD]
The idea of an atemporal realm of validity is as implausible as medieval theology [Heidegger]
Wittgenstein convinced Russell that logic is tautologies, not Platonic forms [Wittgenstein, by Monk]
Logic is not just about signs, because it relates to states of affairs, objects, properties and truth-values [Jacquette]
Logic formalizes how we should reason, but it shouldn't determine whether we are realists [Fisher]
