Knowledge management literature is based on the iceberg metaphor used extensively by Ikujiro Nonaka, which splits the knowledge field into explicit knowledge and tacit knowledge. However, tacit knowledge is a mix of other forms of knowledge which have in common the attribute of being highly personalized. Considering the nature and the way of dealing with knowledge I suggested in some papers to introduce a new metaphor - knowledge as energy - and based on that to consider three basic fields of knowledge: rational knowledge - which is almost equivalent with the explicit knowledge, emotional knowledge - which is the wordless knowledge expressing our emotions and feelings, and spiritual knowledge - which refers to our existential and working values. What do think about this new framework of considering the knowledge spectrum?
