"Discovery consists of looking at the same thing as everybody else and thinking something different."
—Albert Szent-Györgyi, Hungarian-born biochemist and Nobel Prize winner
"You never know what you will learn 'til you start writing. Then you discover truths you never knew existed."
—Anita Brookner, British novelist
"Good writing is clear thinking made visible."
—Bill Wheeler, American writer
Whenever you notice something different, or whenever you are reminded of one thing by another thing, you have caught yourself in the act of comparing or contrasting. When you are faced with two choices, you use your comparison-and-contrast skills to consider similarities and differences between them and make a decision. When you write a comparison-and-contrast essay, you do the same kind of thinking. You use factual details to analyze the similarities and differences between two or more people, places, things, or events.
