These contributions by prominent editors inquire centrally into the relation between philology and philosophy, more specifically the possibility of an inner bond uniting them, of a philological form of knowledge and truth, in short of a philosophy of philology. Alongside studies on the theoretical, methodological and hermeneutic aspects of editing, attention is also given to recent tendencies in editing theory and practice such as édition génétique and New Philology. Finally readers are informed about increasingly important practical and pragmatic aspects of editing, including funding, electronic editing and the copyright issues posed by the latter.
