WebbStrong induction. Strong induction has the following form: A 1 is a B 1. A 2 is a B 2. A n is a B n. Therefore, all As are Bs. An example of strong induction is that all ravens are black because each raven that has ever been observed has been black. Weak induction. But notice that one need not make such a strong inference with induction because ...
