Creativity, pursuit and epistemic tradition.

This paper revisits the standard definition of scientific creativity in the contemporary philosophical literature. The standard definition of creativity says that there are two necessary, and jointly sufficient, conditions for creativity, novelty and value. This paper proposes to characterize the value condition of creativity in terms of "pursuitworthiness". The notion of pursuitworthiness, adopted from the recent debate on scientific pursuit in philosophy of science, refers to a form of prospective epistemic worth. It indicates that a certain object (such as a scientific hypothesis) is promising or has the potential to be epistemically fertile in the future, if further investigated. To support the claim that creative scientific instances are, qua creative, valuable in the sense of pursuitworthy, three examples of creative hypotheses taken from the history of the geosciences are introduced: MacCulloch's continuity hypothesis in mid-19th-century geology, Baron et al.'s phylogenetic hypothesis in contemporary paleontology, and the widely discussed Anthropocene hypothesis.
