In addition to being amusing, this little book is a great introduction to argumentation and more specifically the various common errors in logic. From hasty generalizations (see cartoon) to appeals to irrelevant authorities to straw man arguments, each is described with examples and a clever cartoon as illustration. Scholarship always involves making arguments and budding scholars might find this useful in honing their skills.
