“Deixis”, formally, is a collegiate concept, but chances are, you’ve known its principles most of your life. “Deixis” is the idea that meaning changes with position. For instance, “you” in English changes as the person being spoken to changes. The same goes for “I”, “me”, “they” and other pronouns.
Deixis also exists for time; terms like “later” and “before” depend on where in time “now” is. Also dependent on time is the “dialectic”. The dialectic is the mechanism by which ideas and there meanings interact with the past and slither into the future.
Since deixis and dialectic and are position-dependent, it makes sense that compouding the terms, such as “deictic dialectic” (or “dialectical deixis”) creates a cogent idea, namely that ideas are positional exist in relation to other ideas, whether they remain static or change over time.
