Bradbury also presents this self-knowledge in his stories through the use of water imagery. Bradbury uses water imagery in the traditional sense — that is, to suggest the life source itself and the transition of the life cycle from one phase to another. Water imagery also depicts the theme of rebirth, regeneration, and purification, which Bradbury also uses throughout his writings. He incorporates the rebirth image into his "celebrate life" theme. Bradbury urges us to enjoy being alive in spite of life's difficulties, rather than finding life drudgery because of its difficulties.
Bradbury has high hopes for the future of man and man's acquisition of the most fulfilling life possible (a utopia). He shows his readers a utopian world that can result if they heed his advice, and he describes the horrors that can ensue if certain contemporary tendencies (for example, greed, dependence upon technology, governmental control) aren't stopped. Bradbury always suggests that Earth can be the best possible of all worlds, and he also suggests that humankind, when it has come to grips with itself, can make the world a place in which we can all be as free and as happy as we have ever dreamed.
