4. The “dawn of man” introduction. This kind of introduction generally makes broad, sweeping statements about the relevance of this topic since the beginning of time, throughout the world, etc. It is usually very general (similar to the placeholder introduction) and fails to connect to the thesis. It may employ cliches–the phrases “the dawn of man” and “throughout human history” are examples, and it’s hard to imagine a time when starting with one of these would work. Instructors often find them extremely annoying.
You might be wondering what makes a good thesis statement. First it must be very precise. Words are carefully chosen (this is called diction ) to convey the essay's main point clearly. Because the thesis is the most important sentence in the entire essay, you want to spend some time on it, honing it, carving it out so that its diction is sharp, piercing. The one above is a generalized thesis because it does not map out the 4 forms of retarded technology (remember the class lecture about mapped versus generalized thesis statements). You can use either a mapped thesis or a generalized thesis in your exemplification essay.
