In her Dartmouth commencement speech, Shonda Rhimes employs the definition strategy of exemplification to illuminate the characteristics of "dreamers." Rhimes begins by establishing that "dreamers" are those who "have a vision of something that doesn't exist yet" and "see a world that could be." She then proceeds to provide concrete examples of dreamers, highlighting their tendency to "fantasize about the future" and "imagine a world in which you've achieved your goals." This exemplification strategy allows Rhimes to paint a vivid picture of the dreamer's mindset, emphasizing their focus on the ideal rather than the practical. She further reinforces this definition by contrasting dreamers with "doers," who are those who "take action" and "make things happen." By juxtaposing these two groups, Rhimes underscores the distinction between those who merely envision a better future and those who actively strive to create it. This strategic use of exemplification allows Rhimes to effectively define "dreamers" and encourage her audience to move beyond mere dreaming and embrace the transformative power of action.
