Abstract. Fred. L. Polak explored the mechanisms of social change in terms of “future—visions” held by a community. The future, says Polak, participates actively in the present, providing part of the context within which today's decisions are made. Barbara McClintock acquired her insights in maize genetics by developing “a feeling for the organism.” New insights, she maintains, emerge through a mutual relationship between researcher and subject. Though scholars in different fields, both acknowledge the power of images in the creative process. There is a difference in the extent to which each scientist perceives this power to be available to create new ideas.
