Final answer:
Foster asserts that symbols in literature can carry multiple meanings, enabling rich and varied interpretations that contribute depth to the narrative and theme.
Step-by-step explanation:
According to Foster, symbols in literature are not straightforward entities with fixed meanings; rather, they can have multiple meanings. This multivocal nature allows authors to express ideas in a condensed form and encourages readers to explore various interpretations. Moreover, symbols are deeply rooted in societal communication, carrying meanings that societies have come to recognize and understand. Good writers utilize symbols carefully, and attentive readers can discern a vast array of potential meanings from them. In the context of literature, symbols are used to convey themes, emotions, and concepts, thereby enriching the reading experience and lending depth to the text. For instance, a symbol might convey subtle nuances in theme or character relationships that are left to the audience's interpretation.
