Transition from the reproductive to the creative imagination.--Do all representations contain motor elements?--Unusual effects produced by images: vesication, stigmata; their conditions; their meaning for our subject.--The imagination is, on the intellectual side, equivalent to will. Proof: Identity of development; subjective, personal character of both; teleologic character; analogy between the abortive forms of the imagination and abulias. 3 FIRST PART. ANALYSIS OF THE IMAGINATION. CHAPTER I. THE INTELLECTUAL FACTOR. Dissociation, preparatory work.--Dissociation in complete, incomplete and schematic images.--Dissociation in series. Its principal causes: internal or subjective, external or objective.--Association: its role reduced to a single question, the formation of new combinations.--The principal intellectual factor is thinking by analogy. Why it is an almost inexhaustible source of creation. Its mechanism. Its processes reducible to two, viz.: personification, transformation. 15 CHAPTER II. THE EMOTIONAL FACTOR. The great importance of this element.--All forms of the creative imagination imply affective elements. Proofs: All affective conditions may influence the imagination. Proofs: Association of ideas on an emotional basis; new combinations under ordinary and extraordinary forms.--Association by contrast.--The motor element in tendencies.--There is no creative instinct; invention has not _a_ source, but _sources_, and always arises from a need.--The work of the imagination reduced to two great classes, themselves reducible to special needs.--Reasons for the prejudice in favor of a creative instinct. 31 CHAPTER III. THE UNCONSCIOUS FACTOR. Various views of the "inspired state." Its essential characteristics; suddenness, impersonality.--Its relations to unconscious activity.--Resemblances to hypermnesia, the initial state of alcoholic intoxication and somnambulism on waking.--Disagreements concerning the ultimate nature of unconsciousness: two hypotheses.--The "inspired state" is not a cause, but an index.--Associations in unconscious form.--Mediate or latent association: recent experiments and discussions on this subject.--"Constellation" the result of a summation of predominant tendencies. Its mechanism. 50 CHAPTER IV. THE ORGANIC CONDITIONS OF THE IMAGINATION.
