Word, fact and object are all internal data construct and subject to the same production process.
Therefore, irrespective of possible validity, all such data output is an abstract internal process.
An object, (including appreciable narrative) although subject to the same internal process for validity, nonetheless also involves sensory mechanisms, which allows for a level of certainty.
Nonetheless an appreciable narrative that represents an internal data construct, is only representative of an abstract process.
In short, objective is subjective unless subject to a level of sensory certainty (perhaps)....Though an appreciable narrative does not in itself validate an internal data construct as a representation of an external reality.
In fact, considering the nature of human function and process....I think that it is fair to say that we can never be 100% certain of anything.....Though our ability to be uncertain does offer us a high degree of confidence in our existence......I think therefore I am as it where.
