A person who knows all the answers, has an opinion on everything, has a certainty backed up by rational argument, has very little possibility of further progress. Such a person is unlikely to walk away from a discussion with anything more than a reaffirmation of how right he or she has been all along.
Wie nooit van mening is veranderd, heeft zelden iets geleerd.

The future is a mystery
The past is history
This moment is a gift
Thats why they call it the present
