There is a quote attributed to Lao Tzu, in the 6th century BCE, it says:

“Those who know don’t say, and those who say don’t know.”


Ignoring the paradox that this statement presents (as Lao Tzu was clearly ‘saying‘), I asked Gene Walder of TCSociety…

“Since many ‘say,’ and many ‘do not say,’ how is it possible ever to know?”


…and Gene replied:

“When a father teaches his son, he will say.”
