- Abduction is half of induction, the other half being confirmation.
- One abduces hypotheses on the basis of observations (e.g., these
- seven emeralds are green; perhaps *all* emeralds are green). Then
- one goes on to attempt to confirm this hypothesis with additional
- observations.
-
- See C.S. Peirce's "Abduction and induction" in _Philosophical writings_,
- and then Nelson Goodman's "The new riddle of induction" in _Fact, fiction,
- and forecast_. Then stop thinking about or you'll go crazy. :-)
