I read about a lady, the other day, who, when asked about a controversial idea she was championing declared that she knew that it wasn’t true but that it was consistent with her beliefs so she embraces it. Just an example, I guess, that our deep philosophical divisiveness has morphed into alternate realities. The spin has turned into, at least in some cases, ‘alternative facts’. The information we receive has become not simply differing versions or interpretations of events but actual counter-facts, egregious distortions. The fact checkers, who I tend to trust, have, I suspect, been working overtime to decipher truth from fiction. There are no excuses for those who deliberately misinform to suit their own agendas but I suspect many of us simply experience differently, which has me thinking about what exactly Truth is.
Even life versus death will have nuanced meaning for some I suppose (at least those of a spiritual bent), and like the half empty/ half full glass of water interpretation must be accounted for. As I sit here writing this, I can’t know the truth, when I finish, of where exactly I will be physically, the world turning as it is. I peer out the window at a beautiful blue sky and suspect there are those whose truth upon viewing same will be something other.
So, I guess it’s only fair to assume that what I know to be truly the case will not necessarily be truth for others. I guess we’ll all just have to learn to co-exist in our alternative realities.

A society that cannot or will not share a “consensual reality” (i.e. shared truths) does not bode well for its longevity, I think.
In a paper titled, “Psychotic Group Text: “A Psychoanalytic Inquiry into the Production of Moral Conscience” the author contends that,
‘whereas psychosis in individuals constrains and isolates them, in group settings psychotic behavior unites and energizes its members, relieving the collective of its anxieties.’
He was talking about Germany in the 1930s and how ‘the entire professional, academic, and scientific communities in the dominant group made mass murder possible.’
If we’re not careful about the growth of “alternative realities”, I fear for what might be possible again.
I share your fear, Sudrakarma; I find these alternative realities most unsettling.
