... ability to see possibilities in existing ideas. Making new insights is not merely about being able to synthesize difficult and large amounts of materials, it also involves knowing how to be creative and, perhaps, original. It cannot be overemphasized, however, that to make a new contribution to knowledge you do not have to be a genius. The size of the contribution is not what matters, it is the quality of work that produces the insight." - Chris Hart in "The Literature Review in Research", page 21 and 22.
