Our thesis is that our faith in logic is misplaced. Exclusive emphasis upon logic (even where logic is adroitly used) incapacitates rather than fits the mind to function as a fit instrument of reality adjustment. The supposition that emotional aberrations are to be conquered by heroic doses of logical thinking is a mistake. The absence of effective logic is a symptom of a disease which logic cannot itself cure. We have been misled by supposing that the mind can rely upon a single technique of operation when this isolated technique has serious limitations. A totally different technique of thinking is needed to get on with the task of ridding the mind of the distorting results of unseen compulsions. Since our schools have found no place for the cultivation of this additional technique of thinking, our judges and administrators and policy-makers are turned loose on the world armed with faith in logic and incapable of making their minds safe for logic. Logical thinking is but one of the special methods of using the mind, and cannot itself achieve an adequate inspection of reality because it is unable to achieve self-knowledge without the aid of other forms of thinking. The technique of free-fantasy offers many points of contrast with logical thinking. It is unguided rather than guided association. From a given starting-point, no effort is bent toward the exclusion of the trivial, the trite, the embarrassing, the filthy, the nonsensical. The mind is permitted to run hither and yon. It is hospitable to everything which germinates in the mind, and is subject only to the effort to steer clear of the molds of logical thinking. There is no specific definition of an objective, and no intermittent intervention in the flow of material to register its pertinence or impertinence to this rather specific objective. Free-fantasy is not to be confused with free word associations which begin with simple stimulus words and end when the first few words which pop into the mind are put down. Free-fantasy is not a momentary relaxation of selective criticism, but prolonged emancipation from logical fetters. Free-fantasy differs from the ordinary daydream, the night dream, and the visions which arise in sleeping or waking by the circumstance that it is embarked upon with the vague, generalized purpose of rendering available new subject matter for logical thought. The frequent interventions which characterize logical procedures are suspended, the better to serve the ultimate purposes of reality adjustment. Daydreaming which is not used for this general purpose does not represent a technique for using the mind.
