Final answer:
Public speaking is seen as an art or craft because it involves subjective expression and creativity, aiming to connect with and move an audience through cultural and personal nuances.
Step-by-step explanation:
Public speaking is considered to be an art or craft because it involves creativity, expression, and the ability to connect with an audience. Unlike sciences, which are based on objective measurement and empirical evidence, public speaking is more subjective and varies depending on cultural context, personal style, and the nature of the audience. The purpose of arts such as literature, performing arts, and visual arts, is to communicate and evoke emotions. Public speaking shares this purpose as it is meant to persuade, inform, or entertain an audience. This requires careful consideration of culture, character, thought, and literary skill - much like crafting a character in a play or a narrative in literature. These elements come together to make public speaking a deeply human and creative endeavor, rather than a precise science.
