This complicated experience is necessary since our scale of values is less the outcome of our dialectical than of our other experiences in life. Values change more by the unconscious redefinition of meaning than by rational analysis. Every contact and every procedure which discloses new facts has its repercussions upon the matrix of partially verbalized experience, which is the seeding ground of conscious ideas. One peculiarity of the problem of the social scientist is that he must establish personal contact with his material. The physical scientist who works in a laboratory spends more time adjusting his machinery than in making his observations, and the social scientist who works in the field must spend more time establishing contacts than in noting and reporting observations. What the instrumentation technique is to the physicist, the cultivation of favorable human points of vantage is for most social scientists. This means that the student of society, as well as the manager of social relations, must acquire the technique of social intercourse in unusual degree, unless he is to suffer from serious handicaps, and his training must be directed with this in mind. The experience of the administrator-investigator must include some definite familiarity with all the elements which bear importantly upon the traits and interests of the individual. This means that he must have the most relevant material brought to his attention from the fields of psychology, psychopathology, physiology, medicine, and social science. Since our institutions of higher learning are poorly organized at the present time to handle this program, thorough curricular reconstructions will be indispensable.[59] * * * * * What has been said in this chapter may be passed in brief review. Political movements derive their vitality from the displacement of private affects upon public objects. Political crises are complicated by the concurrent reactivation of specific primitive motives which were organized in the early experience of the individuals concerned. Political symbols are particularly adapted to serve as targets for displaced affect because of their ambiguity of reference, in relation to individual experience, and because of their general circulation. Although the dynamic of politics is the tension level of individuals, all tension does not produce political acts. Nor do all emotional bonds lead to political action. Political acts depend upon the symbolization of the discontent of the individual in terms of a more inclusive self which champions a set of demands for social action.
