Reviewer Comments:

There are problems with this lesson. For starters, it’s sloppily prepared, with paragraphs repeating themselves. The notion of an inductive proof is suspect; there’s really no such thing. We can make conjectures based on induction and the conjectures may be powerful, but they prove nothing. The author would have been on firmer ground noting what can be learned by induction and what by deduction.
