TEIJEIRO, Paula. Strength and Stability. Anal. filos. [online]. 2021, vol.41, n.2, pp.337-349. ISSN 1851-9636.  http://dx.doi.org/10.36446/af.2021.459.

In this paper, I present two presumed alternative definitions of meta-validity for meta-inferences: Local and Global. I defend the latter, first, by arguing that it is not too weak with respect to meta-inference-cases, and that local meta-validity is in fact too strong with respect to types. Second, I show that although as regards meta-inference-schemas Local metavalidity is always stable, Global metavalidity is also stable when the language satisfies reasonable expressibility criteria (and that in fact, both concepts collapse in those cases).

Keywords : Meta-inferences; Local Metavalidity; Global Metavalidity; Substructural Logic.
