 Llull knew that all believers in the monotheistic religions—whether Jews, Muslims or Christians—would agree with these attributes, giving him a firm platform from which to argue.The idea was developed further for more esoteric purposes by Giordano Bruno in the 16th century, and in the 17th century by the "Great Rationalist" Gottfried Leibniz, who wrote his dissertation about Llull's "Art" and integrated it into his metaphysics and philosophy of science.Leibniz gave Llull's idea the name ""ars combinatoria"", by which it is now often known.
