On reality

[W]hen an unendurable frustration occurs and one can change neither one’s nature nor that of those around one, one can only change what one experiences of one’s experience by obliterating the knowledge of the experience, and the knowledge that one obliterated it, by substituting false knowledge in its place. Thus transformed and transfigured, fictive experience makes one oblivious that truth once lived where falseness reigns.

-Harold Boris, Bion Revisited

[S]uppose someone were to drag him away forcibly up the steep and rugged ascent and not let him go until he had hauled him out into the sunlight and, when he had come out into the light, [would he not] find his eyes so full of its radiance that he could not see a single one of the things he was now told were real?

-Plato, Republic
