That enterprise seems an attempt to force nature into the preformed and relatively inflexible box that a paradigm supplies. This forces science to investigate some aspect of nature in minute detail. Kuhn asserted that normal science relaxes its restrictions whenever the paradigm ceases to function effectively, however commitment to the paradigm still prevails. Regarding origins, evolution appears to be the most recent paradigm and in many ways Kuhn exhibits great insight. Kuhn relates several reasons for any new scientific paradigm shift, including a crisis in the original paradigm, the emergence of new and overwhelming empirical evidence, and changes in world view.
History also suggests, however, some reasons for the difficulties encountered on that road.
In the absence of a paradigm or some candidate for a paradigm, all of the facts that could possibly pertain to the development of a given science are likely to seem equally relevant. Thus the wealth of seemingly conflicting data leads to a morass.
