 Llull presents an original contribution he designates as Affatus, which operates in the same way as the five traditional senses. The Affatus is defined as the potentiality by which an animal manifests its conceptions through its voice to another animal. This is the means, as he writes in the Libre dels proverbis de Ramon CCLXII, through which man communicates with the rational soul more than with any other sense, by which the soul produces sound, and, in the case of man, communicates science. It is the image of understanding, it allows communication with God, and it is how the mechanical arts are expressed.
