From Maud Bodkin

Maud Bodkin writes,

When a great poet uses the stories that have taken shape in the fantasy of the community, it is not his individual sensibility alone that he objectifies. Responding with unusual sensitiveness to the words and images which already express the emotional experience of the community, the poet arranges these so as to utilize to the full their evocative power. Thus he attains for himself vision and possession of the experience engendered between his own soul and the life around him, and communicates that experience at once individual and collective, to others, so far as they can respond adequately to the words and images he uses.

We see, then, why, if we wish to contemplate the emotional patterns hidden in our individual lives, we may study them in the mirror of our spontaneous actions, so far as we can recall them, or in dreams and in the flow of waking fantasy; but if we would contemplate the archetypal patterns that we have in common with men of past generations, we do well to study them in the experience communicated by the great poetry that has continued to stir emotional response from age to age.
