  • ‘ Where is the Life we have lost in living? Where is the wisdom we have lost in knowledge? Where is the knowledge we have lost in information?’ T.S. Eliot's The Rock (1934)
  • The Continuum of Understanding * Knowledge has the complexity of experience, which come about by seeing it from different perspectives. This is why training and education is difficult - one cannot count on one person's knowledge transferring to another. Knowledge is built from scratch by the learner through experience. Information is static, but knowledge is dynamic as it lives within us. * Wisdom is the ultimate level of understanding. As with knowledge, wisdom operates within us. We can share our experiences that create the building blocks for wisdom, however, it needs to be communicated with even more understanding of the personal contexts of our audience than with knowledge sharing. * Data comes about through research, creation, gathering, and discovery. * Information has context. Data is turned into information by organizing it so that we can easily draw conclusions. Data is also turned into information by "presenting" it, such as making it visual or auditory. understanding is a continuum (Cleveland, 1982):
  • The Continuum of Understanding understanding is a continuum (Cleveland, 1982): Data Information Knowledge Wisdom
