Then allow me to give you some advice. Although I would like to see you summarizing the main ideas of each article, I would also like you to focus on and work through specific passages. For instance, I hope you would recognize Whitehead's thesis (the argumentive statement that much of his essay seeks to prove--look for it early in his second section).
You might want to work through difficult passage, or a "sound bite" kind of sentence. If you don't know what to write about, try to offer an explication of the following idea:
"It is a libel upon human nature to conceive that zest for life is the product of pedestrian purposes directed toward the narrow routine of material comforts."
What is Whitehead here saying about human nature? Work through word by word (and you probably want to go back and find this passage in the essay!)
