"The only reality I can possibly know is the world as I perceive and experience it at this moment. The only reality you can possibly know is the world as You perceive and experience it at this moment. And the only certainty is that those perceived realities are different. There are as many 'real worlds' as there are people!"
—Carl Rogers, qtd. in Power Partnering
by Sean Gadman, 1996
This may be the root of human conflict. The perception is the reality, but everything we think we understand about others is only in terms of what we know about ourselves, which is by no means certain.
It is to hoot.
