Artificial Intelligence, both as a hope of making substantial progress, and a fear of the unknow n and unimaginable, has its roots in hum an dreams. These dreams are materialized by means of rational intellectual efforts. We see the beginnings of such a process in Lullus’s fancies. Many scholars and enthusiasts participated in the development of Lullus’s art, ars com binatoria. Amongst them, Athanasius Kircher distinguished himself. Gottfried Leibniz ended the period in whic h the idea of artificial intelligence was shap ed, and started the new period, in which artificial intelligence could be conside red part of science, by today’s standards.
