ABSTRACT
In his proposed monograph, Sylvan intended to include material on non-deductive reasoning. E xtant fragments of draft material on this topic are reproduced below as individual chapter sections. They all appear to have been drafted between June and October 1995. [Editors]
13.1 Induction as the converse of deduction: induction and connexive confirmation
The theme that induction is the converse relation of deduction, once widely espoused, has fallen into disrepute. Indeed more, it has been abandoned, though closely related successors have sprung up in its place: nétably the hypothetico-deductive method, and latterly that sceptical usurper that would replace it in turn, with some such variant as corroboration, namely deductivism of Popperian and other forms.
