%0 Journal Article %T The Chemical Core of Chemistry I: A Conceptual Approach %A Joachim Schummer %J Hyle : International Journal for Philosophy of Chemistry %D 1998 %I HYLE Publications, Karlsruhe and University of Karlsruhe %X Given the rich diversity of research fields usually ascribed to chemistry in a broad sense, the present paper tries to dig our characteristic parts of chemistry that can be conceptually distinguished from interdisciplinary, applied, and specialized subfields of chemistry, and that may be called chemistry in a very narrow sense, or 'the chemical core of chemistry'. Unlike historical, ontological, and 'anti-reductive' approaches, I use a conceptual approach together with some methodological implications that allow to develop step by step a kind of cognitive architecture for chemistry, which basically contains: (1) systematic chemical knowledge on the experimental level; (2) clarification of chemical species; (3) chemical classification systems; (4) theoretical foundation through the chemical theory of structural formulas. In a succeeding paper the results will be checked for resisting physicalistic reduction. %K philosophy of chemistry %K chemical properties %K logical structure of chemical knowledge %K pure substances %K chemical classification %K theory of structural formulas %U http://www.hyle.org/journal/issues/4/schumm.pdf
