The Dissertatio de arte combinatoria, which Leibniz published in , was an expansion of the dissertation and theses submitted for disputation the same year . Abstract: This article considers the Dissertatio de Arte Combinatoria, published in and relatively neglected by Leibniz s scholars. However. In , Gottfried Wilhelm Leibniz () published his doctoral dissertation at Leipzig University. In his Dissertation de Arte Combinatoria, he attempted to.

The great German polymath Gottfried Leibniz see biography of Leibniz was one of the first men after Ramon Llull and almost at the same time with Athanasius Kircherwho dreamed for a logical thinking device.

We have to mention also the fact, that Leibniz created the first mechanical calculator, suitable not only for addition and subtraction, but for multiplication also—the Stepped Reckoner. But being an authentic genius and extremely powerful intellect, Leibniz made a huge step forward. In Leibniz published his first book see the upper image of the title pagealso his habilitation thesis in philosophy, Dissertatio De Arte Combinatoria On the Art of Combinationspartly inspired by the Ars Magna of Ramon Llull Leibniz was still a teenager, when he encountered the works of Ramon Lull.

Though the design Leibniz places at the front of his book see the lower figure appears to be a very simple and even trivial diagram, compared to the copperplates of Kircher’s books, disserrtatio entire text which follows speaks a new and different language. Leibniz was only 20, but he analyses as an advanced mathematician the combinayoria power and limits of the art of combination.

In contrast with Llull and Kircher, Leibniz was not at all interested in any esoteric applications of this method, but rather in a way of reproducing the totality of the universe within one science. After reading his very famous treatise on the monads Monadology from monads are something like atoms, situated in the metaphysical realm as a model for the art of combination, his new, radical perspective is at once comprehensible.

### De Arte Combinatoria – Wikipedia

In Leibniz described a machine for solving algebraic equations. A year later, he wrote comparing logical reasoning to a mechanism, thus pointing to the goal of reducing reasoning to a kind of calculation and of ultimately building a machine, capable of performing such calculations.

There is a letter written by Leibniz to Johann Friedrich, Duke of Hanover, in Aprilwhich offers the whole ambitious program of the philosopher. In that letter, we find initially a confession about the source of the method of combination. But then Leibniz starts to criticize Llull and Kircher because in his view, they did not go far enough in using this art of combination.

Regarding his own idea of its use he says: My invention is an innocent magic, a non-chimerical Cabbala, a writing, which everyone can read and which everyone can very easily learn Quite a pathetic proclamation, but that was the style of the great philosopher!

Leibniz apparently believed, that he have invented a general problem-solver, like those in the computer agte have always dreamed of. But of course, his whole super-ambitious program was not to be dissertafio.

Only some aspects of that proclamation were really transposed into useful applications. At first, Leibniz made a few essential steps toward combnatoria calculation of probability, which is obviously a very important problem for all so-called expert-systems, and artificial intelligence in general. He then attempted diesertatio transcribe the whole art of combination into a system dombinatoria formulas because he wanted to calculate every single part of the process, each step diesertatio each result of an interval.

Thus he used consequently his mathematical skills to produce a new kind of combination by transposing meanings into figures and values. Even more—Leibniz was also one of the first men, who realized the importance of the binary system Of course, he is not the inventor of the combijatoria system. Pingala, an otherwise-obscure Indian author, wrote about B. In hid treatise, he uses a binary logic system short-long, in this case, rather than to explore meter in poetry.

Leibniz discovered that computing processes can be done much easier with a binary number coding in his treatises De progressione Dyadica15th March, and Explication de l’Arithmetique Binaire In these clear and lucid treatises in the lower figure is shown the second page of the original manuscript “De Progressione Dyadica”Leibniz analyzed the possibilities of the binary system and, demonstrating its four fundamental operations of calculation—addition, subtraction, multiplication and division—he expressed the conviction that one day in future the machines would use this system.

Though hard to combinatoia, in his 3-pages treatise De progressione DyadicaLeibniz even outlines a calculating machine which works via the binary system: The following method would certainly be very easy to be implemented. They are to be open at those places that correspond to a 1 and remain closed at those that correspond to a 0.

Through the opened gates small cubes or marbles are to fall into channels, through the others nothing to fall. It [the gate array] is to be shifted from column to column as required for the multiplication. The channels should represent the columns, and no ball should be able to get from one channel to another except when the machine is put into motion.

Then all combinatoriz marbles run into the next channel, and whenever one falls into an open hole it is removed. Ee it can be arranged that two always come out together, and otherwise they should not come out. In a note, written later in his life, when he was reflecting on his works, he remembered the old program of the universal art of combination: I thought again about my early plan of a new language or writing-system of reason, which could serve as a communication tool for all combinaforia nations If we had such an universal tool, we could discuss the problems of the metaphysical or the questions of ethics in the same way as the problems and questions of mathematics dissegtatio geometry.

## De Arte Combinatoria

That was my aim: Every misunderstanding should be nothing more than a miscalculation Thus, in the case of dissertaatio controversial discussion, two philosophers disserfatio sit down at a table and just calculating, like two mathematicians, they could say, ‘Let us check it up Another remarkable idea of Leibniz, announced in his February,essay “Lingua Generalis”, was connected closely with his binary calculus ideas.

Leibniz spoke for his lingua generalis or dissertatlo universalis as a universal language, aiming it as a lexicon of characters upon which the user might perform calculations that would yield true propositions automatically, and as a side-effect developing binary calculus. Leibniz was indeed a great inventor, in spite of not realizing his dream of inventing the general problem-solver.

This was impossible with the knowledge and technology, available at his time. To my mind, if we have to appoint the two greatest persons in the history of computers, first definitely will be Gottfried Leibniz, side by side with Charles Babbage.
