Burke proposed that when we attribute motives to others, we tend to rely on ratios between five elements: act, scene, agent, agency, and purpose. This has become known as the dramatistic pentad. The pentad is grounded in his dramatistic method, which considers human communication as a form of action. Dramatism "invites one to consider the matter of motives in a perspective that, being developed from the analysis of drama, treats language and thought primarily as modes of action" ("Grammar of Motives", xxii). Burke pursued literary criticism not as a formalistic enterprise but rather as an enterprise with significant sociological impact; he saw literature as "equipment for living," offering folk wisdom and common sense to people and thus guiding the way they lived their lives.
