Since almost all uses of language are ambiguous and since this ambiguity can only be resolved sometimes, it follows that whatever is not resolved is interpreted subjectively.
Since such subjective interpretations happen many time per day, it follows that individuals will tend to deal with unresolved ambiguity in idiosyncratic ways that tend toward becoming patterns in time.
This results in what we call “personality.” Extroverts seek to define the moment by asserting meaning while introverts tend to wonder about that or just accept the meaning asserted by the extrovert.
A paranoid person sees danger in unresolved ambiguity while a neurotic person worries and reacts to it.
Having experienced early trauma associated with unresolved ambiguity, borderline personalities are acutely aware that something is wrong and often mad about it.
Besides these rough categorizations, all people are molded by their habitual responses to unresolved ambiguity. Personality is little more than a name for our groping attempts to find or manufacture assurance and consistency in a world where little is certain.
Instead of talking about our feelings or pasts, we would all do much better if we talked about how we talk and how we deal with the ambiguity inherent in virtually all significant communication.
Language itself is neutral as a thing in itself, but the way we use it is not neutral. We assume too much and clarify too little.
