Extension.

Caravaggio, St. John the Baptist in the Wilderness, 1605

An observant person sees things overlooked by others. A scientist sees things going on and then asks how these goings-on array themselves into patterns, patterns that are reliable and predictable. A really good scientist--or a really good artist for that matter, anyone whose mind and soul are capable of some extension--sees what is going on, sees the patterns, and asks, 'Why?' What underlying forces are at work? How are those forces exerting themselves? How may we understand? Once pried from the universe by a great mind or a discerning heart, the hard-won understanding may then be conveyed and conferred upon humanity at large.
