[ Think about it. Our situation is one of limited knowledge. Don't we do a disservice in the education of the next generation to pretend otherwise? ]
Life on this planet almost requires a good deal of pretending..
i.e. pretending that we know what we know..
Maybe the pretense keeps us sane.. or saner...
Yes, I'd say we must play our act well. I am convinced that the difference between acting well and dubious pretension is that the true actor reaches out to one who does know all. Only false gods fail to honor that. The lyrics of Sheila Walsh come to mind:
"Suddenly I'm falling out of the sky
Don't let me go, or I will die.
Whose hands are these?
On my trapeze?
Take hold of me and rescue me
Or I will be a tragedy.
