Commenting on the letter to Mersenne in which Descartes described the alphabet of thoughts as a utopia, Leibniz noted:.

Why should an expression not be as long as an entire book? As a preface, combinatoris work begins with a proof of the existence of God, cast in geometrical form, and based on the Argument from Motion. This was impossible with the knowledge and technology, available at his time.

It had been his hope, he qrte, that in this way humanity might acquire a tool which would augment the power of the mind more than telescopes and microscopes had enlarged the power of sight.

He cites the idea of Thomas Hobbes that all reasoning is just a computation.

Had it not been so, the art would not have appeared to Lull as a perfect language, capable of illustrating a divine reality which he assumed from the outset as self-evident and revealed.

He introduced the term variationes ordinis for the permutations, combinationes for the combinations of two elements, con3nationes shorthand for conternationes for those of three elements, etc.
