다음 글을 읽고, 밑줄 친 *“the ephemeral mirror”*가 의미하는 바로 가장 적절한 것을 고르시오. [5점]

In the context of contemporary metaphysical discourse, the nature of self-awareness has often been likened to a reflective surface, one that captures and distorts reality simultaneously. This paradoxical reflection is not a permanent fixture, but rather a fleeting and malleable entity. As Sartre proposed, the 'for-itself' exists only in its awareness of the 'in-itself', creating a subject that is constantly in flux, forever dependent on the momentary interplay of perception and self-reflection. The mind, then, acts as the ephemeral mirror, a transient interface between existence and perception, distorting both while also capturing the essence of neither. In this sense, the self is perpetually reframed and redefined, never truly grasping its own being, but only its reflection at any given moment.
