There is a difference between "education", "intelligence", and "wisdom". Intelligence is the only one of the three that we are born with; the others are all acquired with time. A 16 year old can be quite intelligent, but has not had the life experience to acquire wisdom, nor a long enough life to acquire much education - which explains why teenagers do some really dumb stuff. :D
Things that over-emphasize on rigid thinking - rote learning, subscription to dogma - can stifle the mind, restricting the use of intelligence and preventing the honest thinking that is required to acquire true wisdom. An open mind is crucial. :puffpipe:
