'the armour of the I'

Compare the wild, free paintings of the child with the stiff, pinched "pictures" these become as the painter notices the painting and tries to portray "reality" as others see it; self-conscious now, he steps out of his own painting and, finding himself apart from things, notices the silence all around and becomes alarmed by the vast signification of Creation. The armour of the "I" begins to form, the construction and desperate assertion of separate identity, the loneliness: "Man has closed himself up, till he sees all things through the narrow chinks of his cavern." William Blake, The Marriage of Heaven and Hell.
