“You cannot teach a man anything; you can only help him find it within himself.” – Galileo Galilei (1564 – 1642)
I have heard this from other wise men and personally observed the inability to impart data to those ‘who do not have it within themself’.
I also helps partially explain the failures many of have had over the last 6 years trying to impart to others what seems to be obvious and incontrovertible truths.
