to claim we are living in a post-truth era is to - by definition - also claim that there was previously a truth era and before that, a pre-truth era.
are there truths or is there Truth.
what is truth. is truth fact. is faith truth. is faith fact. if fact is quantifiable, measurable, visible, objective... and faith is conviction of things not seen, then faith cannot be fact. can a non-fact be truth.
whence context. i look like doris day... compared to a pine tree. there are people that will tell you that yoga is a religious experience and people that will tell you that yoga is a sin. we claim different truths because we have access to a wide variety of inputs, yet we lack shared basis for discernment. does that make one of us wrong or are we all merely differently right.
what is the value proposition. when is it worth lying. when is lying wrong. is it a lie to say "we are all winners" - to tell children "we are all winners". is it a lie to say you're beautiful, if it's only true in my eyes.
whence tolerance. is it intolerant to express a singular Truth in the face of someone with a different view. does equating the merit of a view with that of Truth mean that Truth doesn't actually exist (because it's merely a view). or, is Truth a case when intolerance is tolerated.
what is trustworthiness, is it fact or perception, intrinsic or contextual. do we trust people because they are innately trustworthy, or are they deemed trustworthy because we choose to trust. when no one is trustworthy, we are free to choose whom we trust.
when you can't trust anyone, you can trust anyone.
i believe it, therefore it is true.
