  9. Definitions: Data, Information, Knowledge, Understanding and Wisdom • Evaluated understanding • Essence of philosophical probing • Critically questions, particularly from a human perspective of morals and ethics • discerning what is right or wrong, good or bad • A mix of experience, values, contextual information, insight • In computing terms may be unachievable – can a computer have a soul??
