"Seeing is Believing"?

An address by John Hall - recorded on Sunday,21st July, 2019 in the Unitarian Meeting House in Adelaide.
In this address, John raises a fundamental question about our individually unique - even idiosyncratic - perceptions about the nature of reality - about the "real" world that surrounds us and with which we are continually interacting.
Is seeing - believing? Or am I really only "seeing" my individually unique constructions of that reality - revealing more about me than the nature of reality itself? It raises the question that as social beings, how much consensus must there be about our shared sense of "reality" for each of us to be able to remove the "perceptual blocks" to our spiritual growth and live happily and cooperatively together in socially, spiritually-cohesive, and loving communities, within which diversity is valued and celebrated?

NB Some of the interaction between John and his audience has been edited out owing to its reliance on PowerPoint images that this audio-podcast is unable to include.
