Final answer:
Pointing back to oneself or another person in the context of Soviet propaganda signifies completion of a thought and serves as a symbolic direction for the population to follow towards socialism and communism. It parallels the use of reflexive pronouns in the English language, where the pronoun reflects back on the subject.
Step-by-step explanation:
The question appears to be exploring the use of body language and symbolism in the context of historical propaganda, specifically Soviet propaganda. When an individual points back to themselves or to another person, it can signify the completion of a thought, and in the context of Soviet propaganda, it is used as a symbol of guidance and direction. Leaders in propaganda posters often were depicted as the helmsman or train driver, directing the populace along the metaphorical path to socialism and communism. This singular path is presented as the only correct one, with the leader's actions and gaze signifying the direction of movement that must be followed.
From a linguistic standpoint, this can be paralleled with the concept of reflexive pronouns in English, where pronouns 'reflect' back on the subject. For instance, 'John couldn't stop looking at himself in the mirror.' Here, 'himself' is a reflexive pronoun referring back to 'John.' In both the linguistic and propagandistic senses, the act of 'pointing back' demonstrates a closed loop or cyclical reference that reinforces the subject (whether a person in speech or an ideology in propaganda).
