|Inference||Brandom II 76
Material inference/Sellars/Brandom: from a east of b" to "b west of a" - also from lightening to thunder - needs no logic.
Formally valid can be derived from good material inferences, but not vice versa - Proof: given is a subset of somehow privileged vocabulary, so an inference is correct if the material is well and it cannot turn into a poor inference, if non-privileged vocabulary is replaced by non-privileged vocabulary - if one is only interested in logical form, one must be able to distinguish previously a part of the vocabulary as specifically logical - E.g. if you want to examine theological inferences, one must examine which substitution preserves the material quality of the inference when replacing non-theological vocabulary by non-theological.
