摘要：The paper discusses knowledge metaphors as necessities in conceptualizing know-ledge, posing, at the same time, a series of problems of understanding, in a domain characte-rized by fuzziness and multiplicity of interpretations. A classification of main knowledge me-taphors is proposed, pleading for their proliferation, as far as they infuse useful subjectivity and insight in a field which can’t be approached purely rationally.
