In this book, international experts from Europe and the United States address Lullism as a remarkable and distinctive method of thinking and experimenting. The origins and impact of Ramon Llull's oeuvre as a modern thinker are presented, and their interdisciplinary and intercultural implications, which continue to this day, are explored. Ars combinatoria, generative and permutative generation of texts, the epistemic and poetic power of algorithmic systems, plus the principle of unconditional dialogue between cultural groups and their individual members, are the most important coordinates of this combinatorial-dialogical media and communication theory, which appeared very early in the history of science, technology, and art. It was developed in the work of Ramon Llull during the transition from the thirteenth to the fourteenth century when Arab-Islamic, Jewish, and Christian cultures intersected. The legacy of Lullism lives on in poetry and in the visual and electronic-based arts, as well as in research on the history of informatics, formal logic, and media archaeology.
