  2. 2. Goals of the talk §  Get (back) to a bigger picture –  Start from a general point of view in the philosophy of science –  Drill down to implications for every day scientific work (Projects, Publications, PhD Thesis, …) §  Discuss … –  how to allocate the presented methods into that picture –  the methods in context of a PhD dissertation –  the notion of validity and how to increase it 2

  5. 5. What is science? Science: Systematically and objectively gaining (and preserving), documenting, and disseminating knowledge §  In principle, science tries to be objective by aspiring knowledge based on “facts” (independent of subjective judgment!) However: §  Accepting scientific results is a social process (documentation, communication, following rules). §  Some elements of science (mathematics, logics) seem to be unbiased – but nevertheless rely on acceptance by the peers and capabilities to apply the theories. §  One could also say: “In the end, it is also a matter of beliefs, capability, and individual and social judgment” (following some basic principles, rules, and codes) 5

  7. 7. Philosophy and science Ontology (“Seinslehre”) Epistemology (“Erkenntnislehre”) Ethics (“Verhaltenslehre”) Ontological questions (“Außenweltproblem”) Is there a world independent of subjectivity? Epistemological questions (“Erkenntnisproblem”) From ehere do discoveries result?
