Per the author: An idiot, in my book, is the uncommon man who does not understand double talk, abstract paintings, mysticism, or politicians. He is someone who finds the gimmick of memorization inferior to the ability to reason. He is someone who solves problems with a rare and uncommon sense. He is the man who thinks. I would like to lift the fog, eliminate the mystery, and welcome all idiots like myself to a light-hearted, easy-to-read course in navigation. Forget about those $300 computers, slide rules, and four syllable words. Can you add and subtract? Do you have a good imagination? Well then, come along.
