Deduction

Deduction, in Logic, the derivation of a proposition from some more general proposition. Induction leads to new truths, deduction to the application of truths already obtained to new cases. Those who maintain that all our knowledge is derived from experience hold that correct deduction is virtually the application of our past knowledge to a case that turns out to confirm it - in other words, deduction and induction are but varieties of the same process.
