Abstract
Responding to Sorgner’s assertion that “affirm[ing] a concept of truth which claims universal validity […] is totalitarian”, Jorion recalls that the notion of “truth” allows setting up a reference framework whose principles and operation were first described by Aristotle: truth from the evidence of the senses, definitions, and conclusions of well-formed syllogisms.
Persuasion progresses through the extension of shared knowledge between speakers, each showing a disposition to revise his or her existing knowledge.
Such a negotiation mechanism allows, however, local truths to emerge between willing speakers, local truths which might become pervasive in a contentious and polarised world.
That local truths might develop does not make the need for a universal truth reference framework such as scientific knowledge less necessary but even more so.
