Ignorance.

Curtis, Mandan with Skull, 1909

One of the deepest and strangest of all human moods is the mood which will suddenly strike us perhaps in a garden at night, or deep in sloping meadows, the feeling that every flower and leaf has just uttered something stupendously direct and important, and that we have by a prodigy of imbecility not heard or understood it. There is a certain poetic value in this sense of having missed the full meaning of things. There is beauty, not only in wisdom, but in this dazed and dramatic ignorance.

- G.K. Chesterton
