INDUCTION.
Synonyms:
| deduction, | inference. |
Deduction is reasoning from the general to the particular; induction is reasoning from the particular to the general. Deduction proceeds from a general principle through an admitted instance to a conclusion. Induction, on the other hand, proceeds from a number of collated instances, through some attribute common to them all, to a general principle. The proof of an induction is by using its conclusion as the premise of a new deduction. Thus what is ordinarily known as scientific induction is a constant interchange of induction and deduction. In deduction, if the general rule is true, and the special case falls under the rule, the conclusion is certain; induction can ordinarily give no more than a probable conclusion, because we can never be sure that we have collated all instances. An induction is of the nature of an inference, but while an inference may be partial and hasty, an induction is careful, and aims to be complete. Compare [DEMONSTRATION]; [HYPOTHESIS].
