I've heard it said that," A little education is a dangerous thing."
I lean towards believing that. Especially when the partial education pertains to competency in the arena in which one is serving.
Life experience, divine gifting and even destiny are factors that contribute to the performance capabilities of any given individual.
But I want my algebra instructor to be well instructed.
Someone representing the people...well...without any formal education is quite possible as life experience, interpersonal communication skills and being in-tune with the pulse of the people weighs heavily on the value scale.
But being as effective as possible may not be attainable if that individual has not acquired the skill set or developed the often ever evolving knowledge base for the his/her area of concern. That is something that hopefully formal education affords the individual attaining it.
But in the age of the world wide web, Anyone with a basic education can learn and broaden their scope immensely with access to the internet.
I had a little bit of education in computer science during attaining my Elementary Education degree. But I have gotten vastly ahead of all I received there, on my own, via self taught efforts on the internet. The people I create websites for are not at all perturbed that I have no formal education in the field.
I think it is all relative to the field in which the performance is expected and the personal attributes of the individual.
