In 1994 Nicolescu, Morin, and de Freitas drafted the Charter of Transdisciplinarity, highlighting the usefulness of complementing the disciplinary approach in education with a transdisciplinary one. Yet a similar proposition, applied to art making, has already been made at the end of the nineteenth century by the adherents of the artistic movement called Symbolism. The essay examines some Symbolist works by Debussy, arguing that they can be considered as forerunners to a transdisciplinary approach.
