Usage Deduction, induction are names of opposite processes of reasoning, the two ways in which we think. Deduction applies to the process by which one starts with a general principle that is accepted as true, applies it to a particular case, and arrives at a conclusion that is true if the starting principle was true, as in »All female mammals secrete milk; this is a female mammal; therefore, this will secrete milk.
Induction applies to the process by which one collects many particular cases, finds out by experiment what is common to all of them, and forms a general rule or principle which is probably true, as in »Every female mammal I have tested secreted milk; probably all female mammals secrete milk.
