This is called a belief. If we believe that we have perspective on an external event and that our perspective is an authentic perspective, we assign authentic value to those thoughts which we associate as validating our perspective.
In other words:
In this respect: Everyone's truth is a version of a truth, and thus an aspect of truth. If we were in 480 BCE Athens, Caulfield explains, "Alatheia (Truth), the daughter of Zeus, with her right hand upraised, would be simultaneously shielding us from the reproach of a pledge broken and a friend's dues dishonored (Pindar, Olympian Ode 11.6).
Every truth carrier is loaded with libels and keys, reflections and memoirs, accusations and answers. We are those careless carriers who confound the times, mistake the dates, and confuse the stories so that the authors of such stories, including themselves in later years, are wholly a stranger to their words.
Such are the stories we Yahoos tell themselves, and accordingly have great reason to complain. The languages that others use are not proper in their parts. They learned to speak differently. These other Yahoos, their dialect so altered, could hardly understand us if they tried. Yahoos are not able to perceive our conceptions in a manner intelligible to our truth.
Truths are but personal complaints and compliments. Caulfieldian Philosophy instructs one to consider that each individual's rationale, even their own, is a component of truth - and upon that allowance for possible truth, one should follow each subsequent proposition according to the initial principle to determine whether the effects are a truth claim stemming from the belief in the previous proposition. Thus truth lies in a prior correlation to a perception of truth.
Caulfieldian Philosophy is the theory that one's natural perspective of truth cannot be validated or disproved externally. As such, all thoughts are both true and simultaneously untrue. But that is a paradox. If paradoxes cannot exist in nature, neither can truth.
Thus all is perception.
