these beans are white;
Therefore, all the beans from this bag white.

15. Real Examples of Abduction
• You observed that a man’s ring finger has a
scar of ring.Then, he must get married to a
woman (Sherlock Holmes).
• You observed a fossil of shellfish at the foot of
the Andes.Then, you can imagine that the
Andes was under the ocean, long time ago (C.
S. Peirce).
16. A Framework of Abduction and
Induction in LP
• The surprising fact, C, is observed; But if A was true,
C would be a matter of course. Hence, there is a
reason to suspect thatA is true.
• All observed Fs are Gs;
therefore, all Fs are Gs.
All objects in the sample satisfy P(x);
therefore, all objects in the population satisfy P(x).
