INDUCTION.--Deduction is a valuable form of reasoning, but a moment"s
reflection will show that something must precede the syllogism in our
reasoning. The _major premise must be accounted for_. How are we able to
say that all men are mortal, and that lightning in the west is a sure
sign of rain? How was this general truth arrived at? There is only one
way, namely, through the observation of a large number of particular
instances, or through _induction_.
