真实
The authentic is not knowable, but it is experiencable.
Authenticity is an ongoing process, not a static state.
We only live once, so we must live authentically and fully.
Our ideas of what we believe to be, are not of what they are, but only of what they seem to be.
It is indeed an opinion strangely prevailing amongst men, that houses, mountains, rivers, and in a word all sensible objects, have an existence, natural or real, distinct from their being perceived by the understanding.
