ABSTRACT
Harrison, Edward R. Consider the unlearned, unaware of their ignorance, who think they know everything! As knowledge increases, ignorance decreases, but this kind of ignorance-unlearned ignorance-is no more than the lack of knowledge. With knowledge comes awareness of ignorance-learned ignorance-and the more we know, the more aware we become of what we do not know.
Holmes, Oliver Wendell Our task is only that of sending out a few pickets under the starry flag of science to the edge of that dark domain where the ensigns of the obstinate rebel, Ignorance, are flying undisputed.
