There is nothing within the sphere of mind — so argues Mezger (36) — that is devoid ot meaning. But to reach this meaning it is often necessary to substitute the latent content for the mani- fest and conscious content. Thus the psychology of testimony has to discover those biological structures which are called complexes and which by their affective tone turn the will to their own pur- poses. Complexes of this kind which aftect the evidence of the accused are: (1) the complex connected with the deed, (2) the 'will complex' (misrepresentation, lying), (3) Ego complexes con- nected with the whole previous life of the accused, (4) material complexes (Sachkomplexe) based on connections and associations between the relevant things and events, poUtical, social, economic, religious, philosophic and elhical complexes and also sexuality. Frequent reference is made to Freud, but the reader is warned against exaggerations and further proof of Freud's conclusions is demanded.
