In many fields of today’s scientific research there are scholars who deal with symbolic systems such as painting, music or verbal languages. No matter what the main content of every single discipline may be, the real challenge is to build up something like a general theory for languages. It is in this context that we may place the studies of some important philosophers such as János Sándor Petöfi and Nelson Goodman or – in another respect – Willard Van Orman Quine and Donald Davidson, who are taken into consideration by the author of this work. The book is organizaed by using an original mix of theoretical starting points (about the destinies of philology, translation, the theory of notation) and of practical text-analyses (of Greek music and of popular religious painting). The result of such a path is the outline of a new theory of sign and communication called ‘editor theory’.
