There are one-story intellects, two-story intellects, and three-story intellects with skylights. All fact collectors with no aim beyond their facts are one-story men. Two-story men compare reason and generalize, using labors of the fact collectors as well as their own. Three-story men idealize, imagine, and predict. Their best illuminations come from above through the skylight.

Oliver Wendell Holmes (1809 - 1894)
