الاستقراء هو الحكم على كلي بتتبع أكثر الجزئيات
Induction is judging a universal by investigating most of its particular instances.
A judgment about a universal concerns a whole class, such as all animals. Investigating particulars means examining members of that class separately.
The word “most” is significant: moving from what has been examined to a claim about the entire class adds something not yet directly observed.
