The Point of Perspective & the Search for Truth

What is the reality of the point of perception from which one observes oneself within disciplines such as philosophy and psychology?
Is the fullness of the reality of a sphere comprehensible to a point within that sphere, or is this an absurd proposition, and the only way a sphere can know itself fully is existentially as a sphere?
One might argue that the point of perspective expands with knowledge, though one might as easily argue that the point contracts with 'knowledge', since knowledge amounting to the notion of the point within the sphere actually knowing itself as that sphere is an absurdity.
Thus the immeasurably more satisfying indirect, analogous, artistic forms of talking about truth that actually shake the foundations of the point of perspective, rather than the rational abstract means which serve to solidify the illusion of the point, convinced it is growing in knowledge, heading for truth, just around the corner.
The more falsely sure the point within the sphere of its intellectual knowledge, the more abominable the intellectual and ensuing practical results. Thus materialistic communism, fascism/neo-conservatism, etc and a myriad of less obviously insane insanities.
Another variation is the neurotic, where the point's self certainty is undermined, but it has no faith in the sphere within which it has its existence.
