The Celtic peoples, for example, insisted that only the poets could be teachers. Why? I think it is because knowledge that is not passed through the heart is dangerous: it may lack wisdom; it may be a power trip; it may squelch life out of the learners. What if our educational systems were to insist that teachers be poets and storytellers and artists? What transformations would follow?
