I generally think you are referring to our “experience of ourselves and other things in the classical world”, right?
If so, I think you may be regarding some statements as solipsistic assertions that reality arises wholly from our imagination. But that’s not what I think it is. Our senses only assess a tiny fraction of the vibratory spectrum we might call ‘objective reality’. If we want to understand what we sense or discover more than we can directly sense, we employ the pattern-recognizing and pattern-making power of imagination. We settle into patterned ‘grooves’ of personal and social functionality and creativity. These become our realities, but I think they would better be called imaginal domains, or memetic vortexes.
I don’t concur with the suggestion that imagination is the antithesis of reality.
To me they are an integral fabric.
So, for me,
Truth is grokking the well-woven;
Responsibility is the ability to respond within our imaginal domain;
Validity or authenticity is recognizing other domains as co-real.
