Often Reasonable

Dear Editor: Eugene Earnshaw in Issue 119 provides a lively discussion of induction. Precise definition is essential to both deduction and induction. Consider deduction: all who commit murder should be hanged; he committed murder; he should be hanged. Unless we define murder precisely, the conclusion might be that someone who unintentionally killed by misadventure should be hanged – perhaps not what even the most ardent supporter of capital punishment would want. Or take the inductive argument that all swans are white; therefore the swans on your lake will be white.
