“I’m sure” is a very self-limiting expression. It usually means I am certain about something, and I have no doubt about it. Certainty means that I have put aside the fundamental ambiguity of reality, the principles of quantum physics, the uncertainty principle that permeates everything real. Most important, it means I have closed my mind.
Awareness emerges out of the gateway of doubt, not out of the rigid artifice of certainty. Doubt is a gateway to discovery and understanding. It opens my mind and heart to realities that exist beyond my avowed knowledge. Far from being a creature “plagued by doubt”, I embrace my friend Doubt and am grateful for her blessing.
