The first aim of science has been analysis. From Leucippus in the fifth century B.C. to Sir Arthur Eddington today, science has tried to reduce nature to simple structural units. For Leucippus the atoms are structurally alike, though they differ in external characteristics, such as size and shape. The aim of physics today is expressed by Sir Arthur Eddington: “The aim of the analysis employed in physics is to resolve the universe into structural units which are precisely alike one another ... so that all variety originates in the structure and not in the elements out of which the structure is built.” To be sure, that is an ideal. In practice we speak of electrons, protons, neutrons. But that does not alter the problem. The question is: Are there such structural units?

During the past decade or two the influence of theories of language and meaning has made itself felt in almost every field of study, either because, as in the case of psychology and the social sciences, meaning phenomena were part of the subject matter, or because, as in the case of physics and philosophy, the language used in the study demanded analysis and clarification. In recent years there has been (and is being) developed, especially by H. D. Lasswell and his associates, a technique known as content analysis, which attempts to characterize the meanings in a given body of discourse in a systematic and quantitative fashion.

Two essentially different approaches to “truth” should be recognized, although they are not in every respect and on all occasions mutually exclusive. If truth be taken to mean the “most adequate idea (statement, explanation, interpretation, expression) a mind (plural number of minds) is able to perceive at any given time,” the process may, first, be one of immediate intuition, insight or inspiration in which conclusions are arrived at without consciousness of the mediate, detailed steps between recognition of a problem and its solution and without considering all of the possible solutions to the problem; or, it may, second, be one of detailed examination and traversal of the various direct and simple steps to the “truth”, as well as the testing of all other methods of arriving at the same truth. The first method may bring about its result “in a flash”, instantaneously, unpredictably; but the second method is never so rapid, always more laborious, and always consumes more time and energy than the first. That is not to say that the first method always involves less elapsed time between inception and completion than the second; often the first method is marked by delays because the mind in question leaps to other trains of thought before obtaining a solution to the first problem. However, the amount of total time used exclusively to answer the question or solve the problem by the first method is much less than for the second.

Epistemology in modern times has been much influenced by the growth of the mathematical theory of probability. The reverse influence is less obvious, but perhaps equally important. This interrelation affords, moreover, an excellent example of the way philosophic ideas, while directing attention in one fruitful line of inquiry, at the same time may inhibit other discoveries until long overdue.

In my recent paper on Living Systems and Non-living Systems I considered briefly the question of the special rôle assignable to the psychic, as natural factor associated with yet different from the physical, in the activities of living organisms. The general conclusion was reached that this rôle is primarily integrative, in correspondence with the integrative character which is the essential distinguishing feature of the psychic in our experience. As integrative, the psychic factor has a special relation to the synthetic activity so highly developed in living organism, since synthesis is by its nature integration or whole-formation. Originative or novelty-producing activity is the special prerogative of the psychic, rather than simple repetition or routine; the latter, as exemplifying the stable or conservative side of nature, belongs in the field of the physical. According to this conception, the psychic is the source of initiative when action takes on a novel or creative form, as in conscious voluntary activity or (in a broader sense) in natural creative action in general. For example, in animals vegetative or routine processes may be purely physiological and unconscious, while actions requiring special initiative or innovation demand conscious effort and attention.

As individuals and as communities we have suddenly awakened to find ourselves enveloped in a welter of unprecedented changes—social, political, economic and scientific. If our minds are to keep pace with the restless current on which we are being carried along, if our senses are to become alert to the teeming dislocations that mark the present, it will be necessary to raise our sights to the farther reaches of a rapidly oncoming future. In this hurrying hour the outstanding domains of man's thought are found wanting. Accepted tenets in many fields of his activity are giving way to rapidly broadening concepts. In this moment of new assessments it is safe to predict that the field of psychopathology must also gird itself for very radical alterations. It is safe to predict that present-day preoccupations with interpersonal affects, domestic transferences, sexual irregularities, marital conflicts, psychotic episodes, and the vast array of neurotic symptoms that comprise our psychiatric systems will in the scientific reckoning of the future appear to us quite obsolete and inept. They will appear to us as humdrum and archaic, I feel sure, as old wives' tales when contrasted with the basic and encompassing constructs of an organismic phylobiology.
