This volume constitutes a first step towards an ever-deferred interdisciplinary dialogue on cultural traits. It offers a way to enter a representative sample of the intellectual diversity that surrounds this topic, and a means to stimulate innovative avenues of research. It stimulates critical thinking and awareness in the disciplines that need to conceptualize and study culture, cultural traits, and cultural diversity.   Culture is often defined and studied with an emphasis on cultural features. For UNESCO, “culture should be regarded as the set of distinctive spiritual, material, intellectual and emotional features of society or a social group”. But the very possibility of assuming the existence of cultural traits is not granted, and any serious evaluation of the notion of “cultural trait” requires the interrogation of several disciplines from cultural anthropology to linguistics, from psychology to sociology to musicology, and all areas of knowledge on culture. This book presents a strong multidisciplinary perspective that can help clarify the problems about cultural traits.
