EPL 三大元素，在英語寫作的 Rhetoric (修辭學) 裡是必學經典，甚至融入於美國中小學的寫作課程當中。
EPL 由希臘哲學家開始，也僅僅只有希臘哲學探討……，本片陳述「classic rhetoric」，相當深入且精彩！！以下為筆記：
Ethos (intrinsic/extrinsic): Intelligence => appear to be credible; Integrity => good/honest with fairness and consistency--always doing the right thing; Goodwill => have the listeners' best interests at heart.
Pathos: To get the audience emotional involved via Rhetorical questions; Audience-related example; Create a scene in the audience's mind
Logos: make sense. Exposition => clarify/analyze evidence; Argumentation => inductive/deductive reasoning.
除了EPL之外，Rhetoric 還有五大準則 (canons)
Invention => audience/topic/purpose/thesis/main points/supports/research
Arrangement => clear/memorable
Style => figurative language (trope/figure of speech), and diction ( clear/memorable/unbias as not to offend)
Memory => preparation and notes.
Delivery => verbal/nonverbal
Aristotle 的得意門生，精通 Rhetoric 的亞歷山大帝演說，此句的 style 相當精彩："This is what my father Philip did for you, great enough on it's own, but small compared to what you've gained from me"
