All of David's comments seem to apply primarily to history museums. There is a disturbing parochialism in these remarks. I really don't see the harm in a more inclusive essence. In all of the definitions of museums and in most large museum complexes, history is only one wing. Natural history, science and art are equally valid subjects for a museum's enterprise. The study of history, by its nature, must treat the past and its representations as paramount. The study of science and natural history, on the other hand, are barely linked to the provenance of artifacts. The science curator must focus primarily on the development of theory in the context of on going thinking and research. Scientific exhibits never rely heavily on artifacts, as all history exhibits must. If we use David's, or John's for that matter, standards of historical artifact preservation as essential to a "true" museum's mission, then do we not bias any museum toward history as its primary responsibility? Is that a reasonable political position for our profession to take? Do we really want to separate off history as the one true essence of museums, and relegate the analysis and presentation of scientific ideas and the evolving natural world as somehow lesser cousins, outside of the "true" essence of a museum? Are they really suggesting that science has no place in a true museum because collection of artifacts is a minor aspect of its curation? I would never suggest that the history departments focus on preservation of artifacts is somehow outside of the true essence of the museum which I might define as an educational entity whose primary function is to prepare edifying exhibits. Yet David's narrow definition does seem to suggest that the only true object of museology is history. What I am seeking is a definition of essence that can include these somewhat differently focused enterprises that have traditionally been grouped together as museums: art, science, natural history, as well as history. Incidentally, I look forward to further discourse with my muse in the junkyards of both commerce and museology. ========================================================= Important Subscriber Information: The Museum-L FAQ file is located at http://www.finalchapter.com/museum-l-faq/ .
