Gottfried Wilhelm Leibniz
Gottfried Wilhelm Leibniz (born June 21, jul. / 1. July 1646 greg. In Leipzig , Electorate of Saxony ; † 14. November 1716 in Hanover , Electorate of Brunswick-Lüneburg ) was a German philosopher , mathematician , lawyer , historian and political adviser of early enlightenment . He is considered the universal spirit of his time and was one of the most important philosophers of the late 17th and beginning18th century as well as one of the most important masterminds of the Enlightenment . In the 18th century he was often referred to as "Gottfried Wilhelm Freiherr von Leibniz"; however, so far there has been no certification of an ennoblement .
In the early writings of other authors, his surname - analogous to that of his father, Friedrich Leibnütz , and his paternal ancestors - was also written "Leibnütz", sometimes also "Leibnitz" ( French Godefroi Guillaume Leibnitz ). (His name was also Latinized in different versions, e.g. as Godefridus Guilelmus Leibnitius ). From 1671 he chose the spelling "Leibniz" for his family name.
Life
Leibniz was born in Leipzig on June 21, 1646 according to the Julian calendar, which was then valid in the Protestant territories of the Holy Roman Empire , and was baptized on June 23 in Leipzig's Nikolaikirche . His father was the lawyer, notary and professor for moral philosophy ( ethics ) Friedrich Leibnütz (1597–1652) from Altenberg in the Erzgebirge , his mother Catharina the daughter of the Leipzig professor and legal scholar Wilhelm Schmuck . In his second marriage, the father had been married to the daughter of a bookseller. In the estate of the father and his two fathers-in-law there was accordingly an extensive and varied library, to which the early death of the father gave the young Leibniz largely unattended access: "Not only the presence of the books, but also the absence of their owner" laid the Foundation stone for Leibniz's education. Eight years old when he learned in this library self-taught Latin and Greek language; At the age of twelve he developed the beginnings of a mathematical sign language while thinking through logical questions.
Leibniz attended the Nikolaischule in Leipzig from 1655 to 1661 , the original of which has been preserved and renovated. In 1661 he enrolled at the University of Leipzig and pursued philosophical studies with the theologian Johann Adam Schertzer and the philosophy theorist Jakob Thomasius . In 1663 he moved to the University of Jena in order to open up Pythagorean thoughts under the guidance of the mathematician, physicist and astronomer Erhard Weigel .
In 1666, at the age of 19, Leibniz published his first book De Arte Combinatoria (On the Art of Combinatorics). With the first part of this book Disputatio arithmetica de complexionibus he received his doctorate in philosophy from Jakob Thomasius and Erhard Weigel in March of that year . Later that year, at the age of 20, Leibniz wanted to get a doctorate in law, but the Leipzig professors rejected him as too young. So he went to Nuremberg to catch up on what had been denied at the University of Altdorf . He was temporarily in contact with a local alchemical secret society, whose experiments he soon mocked. According to Leibniz's own account, the Altdorf University offered him a professorship after his doctorate, but Leibniz refused.
Instead, he served the Archbishop of Mainz Johann Philipp von Schönborn until 1672 . During his time in Mainz he lived in the Boyneburger Hof, the residence of the Electorate Mainz Court Marshal Johann Christian von Boyneburg , who had given him a job as an employee of Hofrat Hermann Andreas Lasser. He worked with Lasser on a reform of Roman law ( Corpus juris reconcinnatum ) on behalf of the elector . His work Nova methodus discendae docendaeque jurisprudentiae (“A new method to learn and teach jurisprudence”) received a strong reception in relevant circles. In 1670, Leibniz rose to council at the electoral higher revision court despite his Lutheran denomination. In 1671 two treatises on physics were published. Drafts and fragments on metaphysics - which, in the sense of traditional natural theology, should philosophically substantiate basic theses of the Christian faith - and on politics show the wide range of the intellectual project in which these writings were located.
In 1672 Leibniz traveled to Paris at his own request, where he worked as court master for Boyneburg's young son. There he wanted to submit to the "Sun King" Louis XIV a plan for a campaign of conquest against Egypt in order to dissuade him from the planned wars of conquest in Europe. But Leibniz did not dare to hand over the plan; over a hundred years later, however, Napoleon Bonaparte implemented it in the Egyptian expedition . In 1672/73 Leibniz completed work on his calculating machine with a graduated roller for the four basic arithmetic operations , presented them to the Royal Society in London and became a foreign member of this famous learned society. From 1675 he was also a member of the Académie des Sciences in Paris. The dual number system further developed by Leibniz laid the foundation for computer-aided information technology of the 20th century.
Years earlier, from 1668, the Guelph Duke Johann Friedrich had tried to appoint Leibniz as librarian to his residence city of Hanover . But only after several refusals, Leibniz, meanwhile in financial difficulties, finally agreed to the duke in 1676. On the - very long - return trip from Paris he visited his friend Henry Oldenburg in London and his favorite philosophical enemy Spinoza in The Hague .
In Hanover, Leibniz was also appointed court counselor around two years later. There he had a lively exchange of ideas with Electress Sophie von der Pfalz . In addition to his work as a librarian, he had a variety of tasks: from 1682 to 1686 Leibniz dealt with technical problems in the mines in the Upper Harz Mountains. He stayed frequently in Osterode and Clausthal , tried out new mechanical devices there and made numerous suggestions for improving the Upper Harz mining industry . Among other things, Leibniz had developed a horizontal windmill in the Upper Harz in order to optimize the pit drainage. Many of his ideas are still used today, such as the endless rope or the conical rope drum. From 1685 Leibniz traveled through Europe on behalf of the Welfenhaus to write a history of the Welfen - a project that he could not complete until the end of his life. Leibniz was involved in the political successes of the Hanoverian Guelphs, such as the electoral status in 1692 and winning the British royal crown in 1714, through legal opinions.
In 1698 Leibniz moved into the Leibnizhaus in Hanover, which is now named after him . Leibniz let his pupil and secretary, the later scholar Rafael Levi , also live here for years . During the Second World War , the Leibnizhaus was destroyed and in 1983 it was rebuilt elsewhere with a reconstructed facade.
Leibniz was in close contact with other princes and tried to get a paid position. Under Ernst August Leibniz also became librarian of the Herzog August Library in Wolfenbüttel in 1691 . Emperor Leopold I presented Leibniz his plans for a coin reform, for money, trade and manufacturing, for financing the Turkish wars, for building an imperial archive and many other things. But he received only benevolent attention. In 1713 the emperor awarded him the title of Reichshofrat with a small pension; his efforts for the post of Chancellor of Transylvania failed. Leibniz had to turn down the librarian position offered to him in the Vatican as well as that of a chancellor in the Hildesheim Monastery : These positions would have required his conversion to Catholicism. When Leibniz's employer, Duke Georg Ludwig, became King of Great Britain, he refused Leibniz's wish to accompany him to his new court in London: Leibniz stayed in Hanover until the end of his life.
His connections to the Brandenburg-Prussian court, where Leibniz was often a guest, were more successful: Leibniz maintained a close intellectual exchange with Queen Sophie Charlotte , sister of his Hanoverian employer. With the support of Sophie Charlotte, an Electoral Brandenburg Society of Sciences was founded in Berlin in 1700, based on the English and French models. After the coronation of Elector Friedrich III. was renamed to King Friedrich I in Prussia in 1701 in the Royal Prussian Academy of Sciences . Leibniz became its first president. In order to extend this success, he conducted negotiations in Dresden in 1704 and in Vienna in 1713 on the establishment of a Saxon and imperial academy; He also proposed the establishment of a Russian Academy of Sciences to Tsar Peter the Great , which he put into operation in 1724. The academy concept embodied Leibniz's ideal of science, combining theoria cum praxi, theory and practice in systematic cooperation , and is thus at the center of his intellectual project.
Gottfried Wilhelm Leibniz was allegedly at the end of 1711 by Emperor Karl VI. ennobled and raised to the rank of baron; however, the corresponding certificate is missing.
Shortly before his death, relations with the House of Hanover cooled down, which was now under the direction of Georg I. Ludwig . Leibniz died alone on November 14, 1716 at the age of 70 in Hanover and was buried there in the Neustädter Hof- und Stadtkirche St. Johannis . The context of the funeral ceremony is controversial. It is often claimed that only his secretary was present at the funeral and that no clergyman attended the funeral. In contrast, Johann Georg von Eckhart (Leibniz's long-time secretary and collaborator) and Johann Hermann Vogler (his last assistant and Amanuensis ) report that the funeral took place on December 14, 1716 by the court preacher David Rupert Erythropel . Eckhart, who was appointed Hofrat and his successor as librarian and historiographer of the House of Hanover a few days after Leibniz's death , also reports that all colleagues, the officials of the court, had been invited to the funeral, but only Hofrat von Eckhart himself was the only one to appear “ from stand ”.
Hofrat von Eckhart had an ornament attached to the coffin that showed a one within a zero, with the inscription OMNIA AD UNUM (German: "Everything (relates) to the One"), as a reference to the binary number system developed by Leibniz and Its theological interpretation: For Leibniz the 1 stood for God and the 0 for nothing.
On behalf of Friedrich Simon Loeffler , the nephew and heir of Gottfried Wilhelm Leibniz, the librarian Daniel Eberhard Baring compiled a directory of the “Leibniz Library” privately built by the polymath.
Last polymath
Leibniz wrote about himself in French: “Sometimes in the morning so many thoughts come to me during an hour that I am still in bed that I need the whole morning and sometimes the whole day or longer to get them clearly on paper.” He belongs to the early enlightenment and is often referred to as the last universal scholar . He had a strong influence on the subsequent Enlightenment , classical German philosophy, German idealism and the literature of the Weimar Classics . His discoveries in the natural sciences and his philosophical and historical writings are consulted by scholars around the world to this day. As the last great thinker, he represented the science of diverse connections and the analysis of connections, practiced before the 18th century.
Some of his research results and initiatives were:
- Description of the dual system
- Development of the decimal classification
- Plans for a submarine
- Improvement of the technology of door locks
- Device for determining the wind speed
- Advice to doctors about regular fever measurement
- Establishment of a widow and orphan fund
- Proof of the human unconscious
- Infinitesimal calculus (integral calculus and differential calculus)
- Matrices and determinants
- Invention of the staggered roller for a mechanical calculating machine
- Development of the endless chain for ore extraction in mining
- As a friend, colleague and encourager of the then European scribes and author of linguistically influential writings, he was one of the main initiators for the foundation of modern linguistics , especially Indo-European studies .
Philosophy, religion and number
Leibniz viewed science as a unit. His findings in integral calculus , the theory of infinite series , his novel geometry , the theories of combinatorics , the idea of the fundamentals of mathematics and the calculus of probability developed in close connection with his philosophical views. The same applies to his findings on dynamics , to biological and geological conceptions, and to research in the field of practical politics and theoretical history .
Leibniz's philosophical work is grouped around three major problem areas: the monad theory , the concept of determination and the epistemological-logical views.
philosophy
Leibniz has continuously revised his thinking. A condensed presentation of important ideas about metaphysics can be found in his Monadology (1714) - a monad theory .
The problem of the Essais de Théodicée (1710) also appears to have been solved by Leibniz. Our world is the best of all possible worlds , it has a maximum wealth of moments and in this sense the greatest possible diversity.
In his conceptual theory, Leibniz assumes that all terms can be traced back to simple, atomic concepts. He was concerned with how one could assign signs to these concepts and thus in turn derive all terms from them. This is how an ideal language can be built. Among others, the philosophers Russell and Wittgenstein took up this idea and carried it further. With the Ars combinatoria (1666) Leibniz attempted to resume the heuristic project .
Text of the Leibniz quote at the Historisches Museum Hannover:
“There is no desolation, nothing sterile, nothing dead in the world; no chaos, no confusion except an apparent one; roughly as it would seem to rule in a pond if one saw a confused movement and, so to speak, a swarm of fish from a distance, without distinguishing the fish themselves "
Best of all possible worlds
The famous phrase about the “best of all possible worlds” has often been misunderstood, including Voltaire parodying it in his novel Candide . The idea of the “ best of all possible worlds ” should not naively deny or gloss over the actual and great evil in the world. Rather, Leibniz points to a necessary connection between good and bad: namely, there is good that can only be had at the price of the existence of evil. The real world is the best among other things. in the sense that the good in it cannot be realized even by God with a lesser degree of evil. In addition, the “best of all possible worlds” is thought of as dynamic: it is not the current state of the world that is the best possible, but the world with its development potential is the best of all possible worlds.
It is precisely this development potential that makes it possible to improve the current situation, not towards a utopian end point, but more and more, in a never-ending process of constant outbidding development.
Leibniz argues, on the one hand, that some of the evils are only apparent, or that fewer evils in one place would necessitate more in another. He also cites, for example, the diversity that defines the quality of the world. But there is also a logical reason why this has to be the best of all possible worlds. For if God wants to transform a world from the possible into the real, he needs a sufficient reason , since he cannot choose arbitrarily. The only criterion that qualitatively distinguishes a world from all others is to be the best. In contrast to Descartes , for example , Leibniz takes the view that God cannot create or change logical truths. God finds the sum of all possible worlds as well as mathematical theorems. He therefore has no influence on the state and events within a world. Even if he - overriding the laws of nature - works a miracle, this miracle is already fixed once and for all with the selection of the possible world.
One aspect of this is: God created the best of all possible worlds. Since he is all-powerful , all-knowing and all-good, he had to. The evils occurring in the world do not stand in the way of this. Leibniz distinguishes between three types:
- 1. Metaphysical evil
- The metaphysical evil or misery consists in the finiteness of the world. This would be unavoidable if God wanted to create a perfect world.
- 2. Physical evil
- Suffering and pain arise out of metaphysical evil with a certain necessity , since created beings are necessarily imperfect.
- 3. Moral evil
- A created being has the opportunity to be absent or, in theological terms, to sin , because God has given him the gift of free will or freedom.
According to Leibniz, there is no contradiction between determinism and freedom . Although with the choice of the world every action of a person, for example, is completely immovable, the fact that a person behaves in a situation like this and not otherwise is completely free (in the sense of unpredictable). That a person behaves like this (would behave like this) is precisely the reason why the world was chosen. A different behavior would be either logically impossible (not kompossibel with the rest of the world) require a morally inferior world, or would.
The statements about the best of all possible worlds can be seen as anticipation of modern modal logics (e.g. that of Saul Aaron Kripke or David Kellogg Lewis ).
enlightenment
Leibniz formulated the maxim of the rationality of the Enlightenment early on . Quote: “Everyone has the ability to lead a sensible life.” If religion and reason coincide, a true religion would arise. Leibniz postulated that all gifts can spoil a person, that only genuine reason is absolutely salutary for him, but that there will only be no doubt about it if it can prove to be equally clear and certain, like arithmetic , everywhere . In the wake of Pythagoras, the mathematician Leibniz was of the opinion that the deepest secrets are hidden in numbers. That is, if one could express reason with numbers, the objection would be refuted: “How do you know that your reason is better than mine? Which criterion do you have for the truth? "
harmony
Harmony is a defining term in Leibniz's philosophy. He describes harmony as the sum of infinitely many, infinitely small units of force, so-called monads , the original components of the world substance, which were united by God and thus hold the world together.
Leibniz assumes that God created everything out of nothing ( creatio ex nihilo ) and that everything that God created is good. Hence the conclusion that there is a wonderful order to be found everywhere. He gives the numbers as an example , as no changes have been made there.
Leibniz even wanted to use this symbol of the Christian faith for the conversion of the Gentiles. On the other hand, Leibniz also means: "All worldly evil arises from the finite essence of nature". However, imperfection is a necessary partial evil. Ultimately, the actual world is the "best possible of all worlds". Leibniz's popular presentation of many of his basic ideas under the title " Theodicy " deals with, among other things. this elimination of objections allegedly directed to God because of the imperfection of the world and the sufferings experienced.
Monad theory
Leibniz developed the monad theory as an alternative to contemporary trends. The philosophers of the 17th century usually either worked out a new theory of substance or they developed the atomic theory further according to modern standards. Leibniz did not satisfy either of these views. He calls the philosophy of the atomists a "lazy" philosophy, since this view, which regards the atoms as the final building blocks, does not analyze the living, changing world in depth enough. Contrary to atomistic conceptions of time and space, which compare these forms of existence of matter with an empty vessel, Leibniz advocates a dialectical conception in which space and time are relationships of order in the material world. Space is the order of things that exist at the same time, time is the order of their continuous changes.
He takes up the term monad from the Neoplatonic tradition. The term monad , "unity", comes from the Stoicheiosis theologike of the late antique philosopher Proclus .
A monad - the central concept of Leibniz's explanation of the world - is a simple, non-extended and therefore indivisible substance that is inaccessible to external mechanical influences.
The entire universe is formed (in the spontaneously formed by the monads perceptions perceptions ab). They are a kind of spiritual atom, eternal, indivisible, unique. Leibniz thus represents a panpsychistic worldview. The idea of the monad solves the problem of the interaction between spirit and matter, which arises from René Descartes ' system . It also solves the problem of isolation, which appears problematic in Baruch Spinoza's system . There individual living beings are described as merely accidental changes in the only substance . An example: A substance can exist without thinking, but thinking cannot exist without substance.
Since Leibniz idealistically solves the basic question of philosophy and for him matter is only a “difference of the soul”, he rejects the absolute character of space and time. In Leibniz's metaphysics, space and time are understood as order relationships between entities in the material world. Leibniz's theory of substance includes the possibilities of all-round developments. Although the monads are identical in their germs, they develop differently. According to Leibniz, development does not mean the creation of something fundamentally new, but only the unfolding of what is already there. Body , soul and spirit are not fundamentally different, they are just developed differently. Leibniz solves the problem of the connection between body and soul by showing that all monads, although they do not exert any mutual influence on their inner structure, work in a coordinated manner. He claims that God ensured their unity and coordinated action in the creation of the monads. He marks this state with the term “pre-established harmony”. In spite of the idealistic- teleological nature of this view, the effort can be felt to demonstrate the unity of the world and to uncover the laws that work in it.
Legal system
In 1667 Leibniz published a pamphlet on the reform of the legal system. In it he calls for a standardization of the legal works of the Christian nations. He tried to find something true in every religion and to place this in a great harmony , in an all-embracing general religion. With these efforts he moved to the level of an Erasmus of Rotterdam who had a similar goal, namely to create a scholarly republic in which ancient and Christian elements are combined in order to promote tolerance and humanity .
Leibniz strove for peace throughout his life. In 1670 he tried to contribute to a reunion of Catholics and Protestants. Between 1679 and 1702 he negotiated with the bishops Spinola and Bossuet . Until 1706 he tried unsuccessfully to bring together at least the Protestant denominations. These efforts were based on his view that the religious community was an indispensable prerequisite for the preservation of Western culture. All his efforts could not overcome the attachment of the deeply divided countries. Because of this, Leibniz's striving for synthesis and harmony failed .
mathematics
Numbers from the spirit of religion
For Leibniz the motto was: “Without God there is nothing.” Therefore he set the one for God and zero for nothing. At the same time, he examined the language and found that it constantly allows mistakes. This creates enormous communication problems that sooner or later lead to conflicts. Leibniz set the goal of his research to resolve these conflicts. He thought he had recognized that our thinking is actually a calculation process, with which the circle of religiosity and that of God and nothing, of 1 and 0, closes. Consequently, he tried to develop a reliable logical symbol language ( mathesis universalis ). For this he discussed the dual system accordingly: it forms the operational basis of modern computer technology. Leibniz also recognized that every object can be assigned a characteristic number, similar to the arithmetic symbols for natural numbers. With this, according to Leibniz, God wanted to show us that our minds still hold a far deeper secret, of which arithmetic is only a shadow.
Analysis situs
Leibniz founded a mathematics of spatial relationships, which should not be based on numbers and sizes like algebra, but on purely qualitative properties. He called his new science Analysis situs , but also used other terms such as Geometria situs , Calculus situs , Nouvelle characteristique or Analyze géometrique . This later resulted in the topology , which was developed by Johann Benedict Listing in dealing with Leibniz's Analysis Situs.
logic
Leibniz dealt intensively with logic and for the first time propagated a symbolic logic in the form of a calculus . However, he did not publish his logic calculus sketches; it was only very late (1840, 1890, 1903) that they were published. His characteristic numbers from 1679 are an arithmetic model of Aristotle's logic. Its main calculus, he developed into the Generales Inquisitiones of 1686. He designed the first equation there logic and headed in her nearly two centuries before the Boole -Schule the laws of Boolean Association Rules from. Within this calculation he formulated the traditional conceptual logic or syllogistics based on the logic of equations. He invented the set diagrams long before Leonhard Euler and John Venn and used them to represent the syllogistics.
The Leibniz law goes back to him.
calculus
During a stay in Paris from 1672 to 1676 Leibniz came into contact with leading mathematicians of his time. Without a secure theoretical basis, one learned at that time to add up infinite sequences and series . Leibniz found a criterion for the convergence of alternating series ( Leibniz criterion ), from which in particular the convergence of the so-called Leibniz series
follows. Using geometric considerations, he also found their limit value . By adding up series, Leibniz came to integral calculus in 1675 and from there to differential calculus ; he documented his reflections in 1684 with a publication in the acta eruditorum . According to today's standards (priority of the first publication) he would be considered the sole author of the calculus ; However, this interpretation is anachronistic, since scientific communication in the 17th century was primarily oral, through access to manuscripts and by correspondence. Lasting achievement of Leibniz is in particular the still common notation of differentials (with a letter "d" from Latin differentia ), differential quotients and integrals ( the integral sign is derived from the letter S from Latin summa ).
Priority dispute
The English natural scientist Sir Isaac Newton had developed the basic features of calculus as early as 1666. However, he did not publish his results until 1687. Decades later, this resulted in perhaps the most famous priority dispute in the history of science. The first pamphlets accusing Leibniz and Newton of plagiarizing the other appeared in 1699 and 1704. In 1711 the dispute broke out in full sharpness. In 1712 the Royal Society passed an investigation report which Newton himself had fabricated; Johann I Bernoulli responded in 1713 with a personal attack on Newton. The dispute continued after Leibniz's death and poisoned relationships between English and continental mathematicians for several generations. The development of mathematics in England, which for a long time stuck to the technically inferior Newtonian notations, was particularly damaged. Today researchers agree that Leibniz and Newton developed their calculi independently of one another.
Matrix and Dyadic
While working with the matrix calculation, the mathematician found the so-called Leibniz formula for calculating the determinant for a general matrix:
He also developed the dyadic ( dual system ) with the digits 0 and 1 (dual numbers), which is of fundamental importance for modern computer technology .
Leibniz's calculating machine
Many important inventions come from Leibniz, for example a calculating machine and inventions for the use of the wind in pit drainage in the Upper Harz mining industry . Leibniz's adding machine (of which there are five consecutive versions) was a historic milestone in the construction of mechanical adding machines. The staggered roller principle he invented , with which multiplications could be realized in a mechanical way, remained an indispensable basic technology for over 200 years. The precision mechanical problems that had to be overcome when building such a machine were so immense, however, that there are justified doubts as to whether a fault-free machine could ever be realized during Leibniz's lifetime. A flawlessly working replica according to Leibniz's construction plan could only be realized in 1990 by Nikolaus Joachim Lehmann (Dresden).
Quote from Leibniz:
“ It is unworthy to waste the time of excellent people with servile arithmetic work, because when using a machine, even the most simple-minded can safely write down the results. "
In a broader sense, Leibniz pioneered the calculating machine in today's sense, the computer. He discovered that arithmetic processes can be carried out much more easily with a binary number coding , and also that the principles of arithmetic can be linked with the principles of logic by means of the binary number code (see De progressione Dyadica , 1679; or Explication de l'Arithmetique Binaire , 1703). The principles researched here were only used in the construction of calculating machines 230 years later (e.g. in the Zuse Z1 ). Unlike earlier inventors, Leibniz had more philosophical motives when building a calculating machine. With the much sought-after quote that “excellent people are unworthy of slaves losing hours with calculations”, a line is drawn between man and machine. The inventive spirit (freedom, spontaneity and reason) as that which is specifically human is contrasted with the mechanical and technical-natural causality. Leibniz's invention should therefore be seen closely in connection with the work on monadology that appeared around the same time , instead of in connection with practical, i.e. H. commercial, technical and mathematical interests.
The machina deciphratoria
Another “calculating machine” from Leibniz remained concept: the Machina deciphratoria , a cryptological device . He invented the cipher machine as early as the late 1670s, but it was not until 1688 that it was described in a brief for an audience with Emperor Leopold I in Vienna. "In doing so, he anticipated the principle of the rotor key machine by Arvid Damm (1869–1927), according to which the first generation of mechanical cipher machines (from 1918) worked, by almost 200 years."
In the years 2010–2011, Nicholas Rescher reconstructed the principle from Leibniz's notes and Klaus Badur implemented the design in detail, based on which the functioning device was built in 2014 by the G. Rottstedt company in Garbsen. Emperor Leopold did not consider Leibniz's offer any further, as his advisors considered their procedures at the time (wrongly) safe.
How it works: “For the Leibniz machine, the key consists of a) an assortment of six cipher alphabets which are to be placed on the drum together with the associated deciphering alphabets; b) the indication of which of twelve possible gap gears is used; c) the starting position of this gap gear. For the six cipher alphabets you can basically choose from 26! = 1 × 2 ×… × 26 ≈ 4 × 10 26 possibilities. Realistically, the diplomat would hardly have been given more than 50 alphabet pairs in the secret case. But as long as the spy cannot get hold of the suitcase, he has to consider the full range of possibilities. And even with 50 alphabet pairs, there are still 50! / (50 - 6)! = 11,441,304,000 options for mounting them on the drum - including the order of the strips. "
Empirical psychology
Leibniz did not yet use the word psychologia , which was introduced by Johann Thomas Freiius , but wrote mainly in his Monadology and in his New Essays on psychological topics. In the specialist philosophical literature, however, there are hardly any references to Leibniz's area of interest.
Leibniz used the terms perception and apperception to describe the transition from unnoticed sensory perception to conscious perception and its inclusion in individual (self) consciousness . This corresponds to his theory of the law of continuity of minimal changes in physics . The assumption of a continuum with certain sensory thresholds became a guiding principle of experimental psychology and psychophysics by Gustav Theodor Fechner and Wilhelm Wundt . Regarding the relationship between the psychic and the physical in their parallel process ( psychophysical parallelism ), Leibniz postulated that psychological processes follow the principle of purpose ( teleology ), physical processes follow the causal principle . He wrote: “The souls act according to the laws of ends, through endeavors, ends and means. The bodies act according to the laws of effective causes or movements. And the two realms, that of the effective causes and that of the purposeful causes, are in harmony with one another. "
Leibniz's doctrine of principles and his doctrine of volitional activity (striving, desire), detached from the ultimate theological justifications, had a fundamental influence on the thinking and research of Wilhelm Wundt, who is internationally considered the most important founder of modern psychology . Leibniz coined the concept of perspective ( perspectivism ) using the example of different views of the same city. The willingness and ability to change perspective , d. H. Mutually complementary considerations form a basic idea of Wundt's philosophy of science of psychology.
Prehistory and early history
In the dispute over the historical starting area of the Germanic languages or peoples, Swedish researchers such as Olof Rudbeck the Elder represented. Ä. Already in the 17th century the theory that Scandinavia was the " original home " of the Germanic peoples ( Gothicism ). Leibniz contradicted this theory in 1696 in his Dissertatio de origine Germanorum , where he argued - well ahead of his time - with the finding of the names of waters ( hydronymics ). In the scholarly dispute, which has not yet been finally resolved, a growing number of prehistorians (including Rolf Hachmann ) and linguists (including Jürgen Udolph , Wolfram Euler ) have for some time now been tending to the position represented by Leibniz.
Linguistics / Philology
In connection with the dispute about the origin of Germanic , Leibniz also contradicted the view held by contemporary Swedish scholars that archaic Swedish was the original form of the Germanic languages. He also rejected the view, which was still widespread at the time, that Hebrew was the first language of all mankind. In the course of his intensive philological studies, he worked on the question of the origins of the Slavic languages, recognized the linguistic meaning of Sanskrit and was fascinated by classical Chinese .
Paleontology and biology
When a huge prehistoric skeleton was uncovered in a quarry near Thiede , now a district of Salzgitter , in June 1692 , Leibniz used a tooth to prove that it was not the remains of a "giant" that had been found, but the skeleton of a mammoth or elephant seal have.
Johann Georg von Eckhart made the content of the work Protogaeae , which was only published posthumously in 1749, known in terms of content through his own research into the genesis of the world and communications to the French Academy. In counter course were Beringer's Lying Stones of Johann Beringer probably an intrigue of the Jesuits against advocated by Eckhart in Würzburg model of history.
Through the "Protogaea" Leibniz is considered a pioneer of caving and a co-founder of palaeontology , since he did not regard fossils as games of nature, but as fossils of earlier organisms that have disappeared or have been changed by major upheavals in other parts of the world. Leibniz also had first ideas about an evolutionary change of species and suspected, for example, that the different species of big cats could descend from a common original cat species. Some pieces from his collections have been preserved at the University of Göttingen to this day.
Letters
Leibniz was one of the most important interdisciplinary scholars of his era. A large part of his work is documented in letters. Over 20,000 letters to Leibniz have survived from the period between 1663 and 1716, which he received from around 1,100 correspondents in 16 countries. Around 15,000 letters are documented in the Leibniz archive. His correspondents include the natural scientists Christiaan Huygens and Lambert van Velthuysen , lawyers and statesmen such as Samuel von Pufendorf , Magnus von Wedderkop or Veit Ludwig von Seckendorff , the philosophers Thomas Hobbes , Baruch de Spinoza and Jakob Thomasius and the theologian Antoine Arnauld . He was a " homo societatis ". After the invention of his calculating machine, Leibniz received a drawing from the Jesuit Joachim Bouvet , who at that time was studying the I Ching in China, among other things , and on which the arrangement of the hexagrams according to Fu Xi (the author of the I Ching) is shown. On this drawing, Leibniz handwritten the numerical numbers corresponding to the binary code shown .
One of the most informative sources about Leibniz's work, personal and financial circumstances and the situation at the electoral court of Hanover is the intensive correspondence with his Amanuensis Johann Friedrich Hodann (1674–1745), who was in charge of overseeing Hanover when he was away from Hanover for many years and management of the house in Schmiedestrasse and the gardens was transferred.

Correspondence as a UNESCO World Heritage Site
The German Nomination Committee has in the Gottfried Wilhelm Leibniz Library kept in Hannover correspondence of Gottfried Wilhelm Leibniz in 2006 for the UNESCO program World Soundtrack Awards proposed (Memory of the World). In autumn 2007, the General Director of UNESCO made a final decision on the new entry in the Memory of the World Register. In doing so, UNESCO declared the correspondence to be part of world memory and therefore particularly worthy of protection.
The correspondence contains around 15,000 letters with 1,100 correspondents. It is part of the Leibniz estate stored in Hanover with around 50,000 numbers and around 200,000 sheets. The estate also includes Leibniz's library and the only surviving copy of the four-species calculating machine he designed.
Monuments
The Leibniz monument in the inner courtyard of Leipzig University shows Leibniz as a larger than life statue.
In Hanover, two monuments in the public space commemorate Leibniz. The Leibniz Temple in the Georgengarten was consecrated in 1790; it is the first building in Germany dedicated to a non-aristocrat. At Opernplatz there is a bronze silhouette of Leibniz's head created by Stefan Schwerdtfeger , which was inaugurated on November 27, 2008. The 2.5 m high sculpture on a granite base was donated by ten sponsors for 110,000 euros. One side shows the Leibniz quotation Unitas in multitudine (unity of diversity), the other side shows the binary number system developed by Leibniz .

Edited by Stephan Günzel, Bielefeld (transcript) 2007, page 187: “Leibniz intended a mathematics of shape in order to be able to represent the qualitative perceptions, that is, the purely spatial properties of figures, their positional relationships, angles and their mechanical movements. His new analysis should provide a method for the more adequate formalization of figures, machines and motion sequences. Leibniz was interested in methods for precise descriptions of natural bodies, e.g. B. of plants and the structure of animals to develop. Leibniz even hoped to be able to record material properties better, since the quality of the materials can be defined by their fabric or by the specific shape of their sensual parts . "
