VI Abstract In response to this study's guiding research question. Why are writers of scientific texts using metaphor?, botanists and language experts searched scientific journal articles to identify instances of metaphoric language. This examination of metaphor's nature and function focused on four areas; 1) factors that complicate metaphor identification; 2) perceptions about definitions of metaphor and its functions in scientific texts; 3) the social character of the scientific community as a disciplinary influence; and 4) the role of audience in the scientist-authors' perception and use of metaphor. Conclusions I drew represented each of those four areas. First, participants' identification of metaphors was complicated by factors such as connotations, synonyms, and references to human characteristics. Second, participants struggled to agree about what a metaphor is and does regardless of how well acquainted they were with definitions of metaphor and or how well trained to recognize metaphor. Participants' mental images or "senses" about metaphor worked as effectively in the task as exposure to examples and classifications of metaphor's characteristics. Third, participants' place in the discipline seemed to influence ability to identify metaphors because disciplinary conventions seemed to erase metaphoricity. Finally, scientist-authors said they use more metaphors when communicating with less technically aware audiences, although they also used metaphors when writing for professional colleagues. According to participants, metaphors appeared to function in the scientific journal articles in the following ways: clarifying or describing, ornamenting, emphasizing, and persuading. Chapter One iNTRODUCnON AND REVIEW OF LITERATURE The words of Samuel Johnson title this document because they reflect what I believe is an essential characteristic and benefit of metaphor: an unparalleled combination of concision, clarity, and inventiveness. Johnson said, "As to metaphorical expression, that is a great excellence in style, when it is used with propriety, for it gives you two ideas for one" ("Metaphor/' Princeton 491). Johnson broached several important caveats in that statement. First, metaphor is (or is perceived to be) a matter of style. Next, metaphor must be managed with care. And, finally, if care is given, understanding comes in the form of two ideas instead of just one. That temptation to mine metaphor for more, as posed by Johnson, is curbed by a complication raised by a contemporary researcher and technical editor. Joseph Harmon examined metaphor in scientific citations and discovered the difficulty of coimting metaphors in context. His words reflect different—^but equally compelling—considerations about metaphor: ". metaphor (as well as simile and analogy) is easy to define but not always easy to recognize when you see it" (181). Harmon's assertion that knowing a definition and being able to apply it in context embraces the two distinctive (and difficult) tasks that I revisit in the following pages. Those tasks, knowing what metaphor is and recognizing its presence, enrich what this document maintains as fundamental principles about metaphor. According to Johnson and Harmon, those principles offer that metaphor may benefit those who read it and write it and that those who use metaphor may not even be aware of its presence or realize the deeds it accomplishes in their work. The figure's attraction to scholars of not only rhetoric and professional communication but alsoof psychology, linguistics, and philosophy appears to be substantial. The sentiments of Samuel Johnson are echoed with only slight variation by Harmon and many others. Correspondingly, the histories of metaphor are shaped by perceptions of the natureand functions of the figure. This document reveals that those histories
