inferring something present from something absent

[Reciprocality]

Hello people

 

Inferring what must be true about something from the absence of another thing about it, why can this succeed?

To say or write is to appear with an intent, this intent is ineffective without a prediction of the recipient for whom we are appearing, these predictions require some coherence among one another to not themselves becoming the problem, that coherence is a model of reality, is it always this model we tap into when we infer positives from negatives, when we infer that something particular causes something to lack a given expected property? 

What is going on with the narrative in our rhetorical intents, is there some universal law to these that can be identified, how invariant are the fibres or quality in these intents among us? At which level of analysis are they identical and could we say that most below that level are inessential to the real meaning of the intent that allows us to converse with anyone?

It appears that to say anything at all to anyone without triviality we must in our own head construe their absence of that knowledge, what is different between this tendency of construal and ego separation if there really is only one experience, thus one knowledge, and we all tap into it?
