Nonfallacious Arguments from Ignorance

چکیده

THE argument from ignorance has traditionally been classified as a fallacy, but there is growing recognition that this kind of argument can be nonfallacious in some cases.

It is argued that they are best judged as fallacious or not in a particular case, in relation to a context of use in dialogue.

Also, I criticize the viability and the importance of Le Morvan’s distinction between propositional and ...

The critical discussion is clearly a major context of dialogue to use as a normative model in evaluating arguments as fallacious or not.1 However, this paper will study other types of dialogue that cluster around the edges of the critical discussion.
