Normative theory and practical experience do not sharply conflict with one another, but are interwoven intensively. Ensuing from this hypothesis, the interdisciplinary study explores the relationship between philosophical reasoning and social practice. Starting from three exemplary cases of tensions and debates regarding Islamic symbols and rites (headscarf, building of mosques, ritual slaughter) and selected theories out of the socio-philosophical discourse of multiculturalism, the study aims at investigating not only how normative theory and social practice are consistent with one another but also how they are capable of being connected to each other. By combining different methodological (empirical and theoretical) approaches a constructive outcome to the theoretical debate of multiculturalism can be achieved. It is shown: A combination of different methodological approaches proves to be promising in the face of todays multicultural challenges.
