Psychological analysis of these imaginative works shows that this explanation is untrue. That the bizarre and apparently novel products arise from the experiences of the author, revived in imagination and combined in new ways. The horrendous incidents depicted in Dante's "Divine Comedy" never occurred within the lifetime experience of the author as such. Their separate elements did, however, and furnished the basis for Dante's clever combinations. The oft-heard saying that there is nothing new under the sun is psychologically true. In the light of this brief analysis of products of the imagination we are ready to develop a program which we may follow in cultivating an active imagination. Recognizing that images have their source in sensory experience, we see that the first step to take is to seek a multitude of experiences. Make intimate acquaintance with the objects of your environment. Handle them, tear them apart, put them together, place them next to other objects, noting the likenesses and differences. Thus you will acquire the stuff out of which images are made and will stock your mind with a number of images. Then when you wish to convey your ideas you will have a number of terms in which to do it--one of the characteristics of a free-flowing imagination. The second characteristic we found to be variety. To secure this, seek a variety of sensational experiences. Perceive the objects of your experience through several senses--touch, smell, sight, hearing, taste. By means of this variety in sensations you will secure corresponding variety in your images. To revive them easily sometimes requires practice. For it has been discovered that all people do not naturally call up images related to the various senses with equal ease. Most people use visual and auditory images more freely than they do other kinds. In order to develop skill in evoking the others, practise recalling them. Sit down for an hour of practice, as you would sit down for an hour of piano practice. Try to recall the taste of raisins, English walnuts; the smell of hyacinths, of witch-hazel; the rough touch of an orange-skin. Though you may at first have difficulty you will develop, with practice, a gratifying facility in recalling all varieties of images. The third characteristic which we observed in works of the imagination is vividness. To achieve this, pay close attention to the details of your sensory experiences. Observe sharply the minute but characteristic items--the accent mark on _après_; the coarse stubby beard of the typical alley tough. Stock your mind with a wealth of such detailed impressions. Keep them alive by the kind of practice recommended in the preceding paragraph. Then describe the objects of your experience in terms of these significant details.
