2.3 How to write definitive statement paragraphs- Contrasts, Contraries, Examples- Lesson 3 of 3
Not all contrasts involve the negative form of statement; but every contrast, whether negative or positive in form, has the effect of a closer definition of the main idea.
We see a thing more clearly and we define an idea more accurately, when it is contrasted with something else and when its negative or its contrary is stated.
