And then it hit me.
Each of those sources is like each of the individual ingredients found in my favorite granola bars (Clif's new Mojo bar, mountain mix or peanut butter pretzel flavor to be exact), and like those ingredients, when melted into one unified form they serve a greater good.
You see, there are ingredients in those bars that, individually, I do not care for—just as with some of the journal excerpts on writing center pedagogy floating around in my brain. However, when those ingredients that I would not eat alone on a normal basis (e.g., raisins, chocolate chips) are added to others that I happen to love (e.g., sesame seeds, pretzels, peanut butter flavoring), the sum of them form a unified whole that happens to delight my taste buds.
Similarly, I presume that as I take in all of the opinions of authors and let them simmer in my mind until they form a conglomerate of goodness, eventually all of the arguments will somehow complement each other enough to form a delightful whole. At least, this is my hope.
Postscript: Please let me know if this doesn't make sense, and really sounds more like an addiction to the new Clif bar versus an insightful analogy. They really are quite good!
