                     Leibniz’s medallion for the Duke of Brunswick                  from Postdoctoral Thesis by Johann Bernard Wiedeburg of Jena (1718)                                                                

The Universal Language of Machines

The success of the computer as a universal information-processing machine lies essentially in the fact that there exists a universal language in which many different kinds of information can be encoded and that this language can be mechanized. This would concretize the well-known dream of Leibniz of a universal language that would be both a lingua characteristica, allowing the ‘’perfect’’ description of knowledge by exhibiting the ‘’real characters’’ of concepts and things, and a calculus ratiocinator, making it possible for the mechanization of reasoning. If such a language was employed, Leibniz said, errors in reasoning would be avoided, and endless philosophical discussions would cease at once by having all philosophers sit aroung a table and say ‘’calculemus’’.

 Leibniz  .  .  .  found a predecessor [of his binary number system] in Abdallah Beidhawy, an Arab scholar of the thirteenth century. A few other authors also proposed binary notations during the seventeenth century, but it was not until its ‘’discovery’’ and publication by Leibniz in 1703 that it started a growing interest in non-decimal numerical systems. Leibniz’s invention can be traced back to 1697, in a letter to the Duke of Brunswick detailing the design of a medallion (see figure), but he delayed its publication until finding an interesting application. The one he choose was the explanation of the Fu-Hi figures, the hexagrams of the I-Ching, or book of changes, from ancient China, that have been communicated to him in 1700 by the Father Bouvet, a jesuit missionary in China. Two centuries and a half later, binary notation found another application with a much broader impact : digital computers.

This tomb holds Diophantus. Ah, what a marvel! And the tomb tells scientifically the measure of his life. God vouchsafed that he should be a boy for the sixth part of his life; when a twelfth was added, his cheeks acquired a beard; He kindled for him the light of marriage after a seventh, and in the fifth year after his marriage He granted him a son. Alas! late-begotten and miserable child, when he had reached the measure of half his father’s life, the chill grave took him. After consoling his grief by this science of numbers for four years, he reached the end of his life.

I have met with but one or two persons in the course of my life who understood the art of Walking, that is, of taking walks—who had a genius, so to speak, for SAUNTERING, which word is beautifully derived “from idle people who roved about the country, in the Middle Ages, and asked charity, under pretense of going a la Sainte Terre,” to the Holy Land, till the children exclaimed, “There goes a Sainte-Terrer,” a Saunterer, a Holy-Lander. They who never go to the Holy Land in their walks, as they pretend, are indeed mere idlers and vagabonds; but they who do go there are saunterers in the good sense, such as I mean. Some, however, would derive the word from sans terre without land or a home, which, therefore, in the good sense, will mean, having no particular home, but equally at home everywhere. For this is the secret of successful sauntering. He who sits still in a house all the time may be the greatest vagrant of all; but the saunterer, in the good sense, is no more vagrant than the meandering river, which is all the while sedulously seeking the shortest course to the sea. But I prefer the first, which, indeed, is the most probable derivation. For every walk is a sort of crusade, preached by some Peter the Hermit in us, to go forth and reconquer this Holy Land from the hands of the Infidels.

It is true, we are but faint-hearted crusaders, even the walkers, nowadays, who undertake no persevering, never-ending enterprises. Our expeditions are but tours, and come round again at evening to the old hearth-side from which we set out. Half the walk is but retracing our steps. We should go forth on the shortest walk, perchance, in the spirit of undying adventure, never to return— prepared to send back our embalmed hearts only as relics to our desolate kingdoms. If you are ready to leave father and mother, and brother and sister, and wife and child and friends, and never see them again—if you have paid your debts, and made your will, and settled all your affairs, and are a free man—then you are ready for a walk.

Walking, Henry David Thoreau

That a city then precedes an individual is plain, for if an individual is not in himself sufficient to compose a perfect government, he is to a city as other parts are to a whole; but he that is incapable of society, or so complete in himself as not to want it, makes no part of a city, as a beast or a god. There is then in all persons a natural impetus to associate with each other in this manner, and he who first founded civil society was the cause of the greatest good; for as by the completion of it man is the most excellent of all living beings, so without law and justice he would be the worst of all, for nothing is so difficult to subdue as injustice in arms: but these arms man is born with, namely, prudence and valour, which he may apply to the most opposite purposes, for he who abuses them will be the most wicked, the most cruel, the most lustful, and most gluttonous being imaginable; for justice is a political virtue, by the rules of it the state is regulated, and these rules are the criterion of what is right.

“The calculator is helping to define society’s most complicated problems.  It is a tool for turning inspiration into fruitful prediction.  As an information machine, it has done much to broaden the base of our growing concepts.  But the real miracle is the promise that there will also be room for those smallest details that have been the basis for man’s most rewarding wishes.  This is the story of a technique in the service of mankind.”
