John F. Sowa on Analogy

Many observers have said that analogy plays an important role in legal reasoning.
John F. Sowa makes the following interesting comment:
Formal reasoning is based on a disciplined use of analogy:

• Induction:  Generalize multiple cases to create rules or axioms.
•  Deduction:  Match (unify) a new case with part of some rule or axiom.
• Abduction:  Form a hypothesis based on aspects of similar cases.
