The purpose of education is to replace an empty mind with an open one. (Malcolm Forbes, 20th century American entrepreneur and publisher)
Remember readin’, writin’, and ‘rithmetic? It was mostly just cramming our brains with facts, dates, and ideas. And with that we very likely had a mind that was closed to new ideas and new ways of thinking. Forbes had a better idea: teach students to approach ideas with a mind open to discern truth and evaluate various courses of action carefully.
Instruct the wise and they will be wiser still; teach the righteous and they will add to their learning (Proverbs 9:9).
