"Some great writers produce a profound effect by their work as a whole, but are not readily quotable; others have the gift of condensing their meaning into a striking phrase. The conscious and deliberate literary artist will generally be found to belong to the latter class. Pope, for example, is the most quotable writer in English after Shakespeare. Stevenson stands intermediate. On the whole, he rather diffuses his meaning, and makes it an atmosphere enfolding everything; but at times his skill in words concentrates itself in a sentence or phrase, or even in a word."
