Which part of the paragraph does the three elements of emphasis applied?

(Paragraph Writing)
Emphasis has three elements: proportion, varieties and repetition.

A friend says, 'Philosophy' in Doctor of Philosophy (PhD) refers to the amount of systematic examination of concepts or knowledge a degree holder possesses in his profession. Likewise, philosophy is termed to the principle common people are keeping. For instance, P.H.D., which stands for Prayer and Perseverance, Hardwork and Humility, and Dedication and Determination are principles in life that have been examined and proven by their experience. Thus, these common people can live like those professionals having a Ph.D. degree if they also keep their own PhD in life.
Can you help me to trace which part of the paragraph do the three elements applied?
