Göran Sundholm (Leiden University):
“Inference versus Consequence” revisited revisited: Steps towards The current account of the Validity of Inference.

Abstract

• The blindness of consequence (Prawitz 1974, 1985)
• The difference between inference and consequence (Sundholm 1997)
• Epistemic assumptions (Sundholm 1997)
• The vacuous validity of inferences with contradictory premises (Prawitz 2009)
• Validity as transmission of knowledge leads to circular definition of demonstration (Martin-Löf 2009)
• “When I say Therefore  I give others permission to assert the conclusion on my authority, given theirs for asserting the premises” (Sundholm 2009)
• Breaking the circularity by a dialogical distinction between two kinds of knowledge (Martin-Löf 2014), namely
• Assertoric versus apodictic knowledge (Klev 2022).
