He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect and classify animals, plants, and minerals, while publishing several volumes.

Whenever he was upset, he was given a flower, which immediately calmed him. Nils spent much time in his garden and often showed flowers to Linnaeus and told him their names. Soon Linnaeus was given his own patch of earth where he could grow plants. Blunt (2004), p. 15. Carl's father was the first in his ancestry to adopt a permanent surname.

Early education

Linnaeus's father began teaching him basic Latin, religion, and geography at an early age. When Linnaeus was seven, Nils decided to hire a tutor for him. The parents picked Johan Telander, a son of a local

in 1717. Stöver (1794), p. 5. Linnaeus rarely studied, often going to the countryside to look for plants. At some point, his father went to visit him and, after hearing critical assessements by his preceptors, he decided to put the youth as an apprentice to some honest cobbler. He reached the last year of the Lower School when he was fifteen, which was taught by the headmaster, Daniel Lannerus, who was interested in botany. Lannerus noticed Linnaeus's interest in botany and gave him the run of his garden. He also introduced him to Johan Rothman, the state doctor of Småland and a teacher at (a

) in Växjö. Also a botanist, Rothman broadened Linnaeus's interest in botany and helped him develop an interest in medicine. Blunt (2004), p. 16. Stöver (1794), pp. 5–6. By the age of 17, Linnaeus had become well acquainted with the existing botanical literature. He remarks in his journal that he "read day and night, knowing like the back of my hand, Arvidh Månsson's Rydaholm Book of Herbs, Tillandz's Flora Åboensis, Palmberg's Serta Florea Suecana, Bromelii's Chloros Gothica and Rudbeckii's Hortus Upsaliensis".

Rothman showed Linnaeus that botany was a serious subject. He taught Linnaeus to classify plants according to Tournefort's system. Linnaeus was also taught about the sexual reproduction of plants, according to

Professor Kilian Stobæus, natural scientist, physician and historian, offered Linnaeus tutoring and lodging, as well as the use of his library, which included many books about botany. He also gave the student free admission to his lectures. Blunt (2004), pp. 21–22. Stöver (1794), p. 15. In his spare time, Linnaeus explored the flora of Skåne, together with students sharing the same interests. Stöver (1794), pp. 14–15.


Uppsala

In August 1728, Linnaeus decided to attend

on the advice of Rothman, who believed it would be a better choice if Linnaeus wanted to study both medicine and botany. Rothman based this recommendation on the two professors who taught at the medical faculty at Uppsala:

and . Although Rudbeck and Roberg had undoubtedly been good professors, by then they were older and not so interested in teaching. Rudbeck no longer gave public lectures, and had others stand in for him. The botany, zoology, pharmacology and anatomy lectures were not in their best state. Blunt (2004), pp. 23–25. In Uppsala, Linnaeus met a new benefactor, Olof Celsius, who was a professor of theology and an amateur botanist. Blunt (2004), pp. 31–32. He received Linnaeus into his home and allowed him use of his library, which was one of the richest botanical libraries in Sweden. Stöver (1794), pp. 19–20. In 1729, Linnaeus wrote a thesis, ' on plant sexual reproduction. This attracted the attention of Rudbeck; in May 1730, he selected Linnaeus to give lectures at the University although the young man was only a second-year student. His lectures were popular, and Linnaeus often addressed an audience of 300 people. Blunt (2004), pp. 32–34. In June, Linnaeus moved from Celsius's house to Rudbeck's to become the tutor of the three youngest of his 24 children. His friendship with Celsius did not wane and they continued their botanical expeditions. Blunt (2004), pp. 34–37. Over that winter, Linnaeus began to doubt Tournefort's system of classification and decided to create one of his own. His plan was to divide the plants by the number of

s. He began writing several books, which would later result in, for example, ' and '. He also produced a book on the plants grown in the , '. Blunt (2001), pp. 36–37. Rudbeck's former assistant, Nils Rosén, returned to the University in March 1731 with a degree in medicine. Rosén started giving anatomy lectures and tried to take over Linnaeus's botany lectures, but Rudbeck prevented that. Until December, Rosén gave Linnaeus private tutoring in medicine. In December, Linnaeus had a "disagreement" with Rudbeck's wife and had to move out of his mentor's house; his relationship with Rudbeck did not appear to suffer. That Christmas, Linnaeus returned home to Stenbrohult to visit his parents for the first time in about three years. His mother had disapproved of his failing to become a priest, but she was pleased to learn he was teaching at the University. Anderson (1997), p. 40.


Expedition to Lapland

During a visit with his parents, Linnaeus told them about his plan to travel to

It was also during this expedition that Linnaeus had a flash of insight regarding the classification of mammals. Upon observing the lower jawbone of a horse at the side of a road he was travelling, Linnaeus remarked: "If I only knew how many teeth and of what kind every animal had, how many teats and where they were placed, I should perhaps be able to work out a perfectly natural system for the arrangement of all quadrupeds."

One of the first scientists Linnaeus met in the Netherlands was Johan Frederik Gronovius, to whom Linnaeus showed one of the several manuscripts he had brought with him from Sweden. The manuscript described a new system for classifying plants. When Gronovius saw it, he was very impressed, and offered to help pay for the printing. With an additional monetary contribution by the Scottish doctor Isaac Lawson, the manuscript was published as ' (1735). Blunt (2001), p. 98. Anderson (1997), pp. 62–63.

. He failed to make Dillenius publicly fully accept his new classification system, though the two men remained in correspondence for many years afterwards.

Rector of Uppsala University

In 1750, Linnaeus became rector of Uppsala University, starting a period where natural sciences were esteemed. Perhaps the most important contribution he made during his time at Uppsala was to teach; many of his students travelled to various places in the world to collect botanical samples. Linnaeus called the best of these students his "apostles".#Gribbin, Gribbin & Gribbin (2008) His lectures were normally very popular and were often held in the Botanical Garden. He tried to teach the students to think for themselves and not trust anybody, not even him. Even more popular than the lectures were the botanical excursions made every Saturday during summer, where Linnaeus and his students explored the flora and fauna in the vicinity of Uppsala. Blunt (2004), pp. 173–174.


''Philosophia Botanica''

Linnaeus published ''Philosophia Botanica'' in 1751. The book contained a complete survey of the taxonomy system he had been using in his earlier works. It also contained information of how to keep a journal on travels and how to maintain a botanical garden. Blunt (2004), p. 221.


''Nutrix Noverca''

During Linnaeus's time it was normal for upper class women to have wet nurses for their babies. Linnaeus joined an ongoing campaign to end this practice in Sweden and promote breast-feeding by mothers. In 1752 Linnaeus published a thesis along with Frederick Lindberg, a physician student, based on their experiences. In the tradition of the period, this dissertation was essentially an idea of the presiding reviewer (''prases'') expounded upon by the student. Linnaeus's dissertation was translated into French by Jean-Emmanuel Gilibert, J.E. Gilibert in 1770 as ''La Nourrice marâtre, ou Dissertation sur les suites funestes du nourrisage mercénaire''. Linnaeus suggested that children might absorb the personality of their wet nurse through the milk. He admired the child care practices of the Lapps and pointed out how healthy their babies were compared to those of Europeans who employed wet nurses. He compared the behaviour of wild animals and pointed out how none of them denied their newborns their breastmilk. It is thought that his activism played a role in his choice of the term ''Mammalia'' for the class of organisms.


''Species Plantarum''

Linnaeus published ''Species Plantarum'', the work which is now internationally accepted as the starting point of modern botanical nomenclature, in 1753.#Stace, Stace (1991)
p. 24
The first volume was issued on 24 May, the second volume followed on 16 August of the same year. The book contained 1,200 pages and was published in two volumes; it described over 7,300 species. Stöver (1794), pp. 198–199. The same year the king dubbed him knight of the Order of the Polar Star, the first civilian in Sweden to become a knight in this order. He was then seldom seen not wearing the order's insignia. Blunt (2004), p. 166.


Ennoblement

Linnaeus felt Uppsala was too noisy and unhealthy, so he bought two farms in 1758: Hammarby and Sävja. The next year, he bought a neighbouring farm, Edeby. He spent the summers with his family at Hammarby; initially it only had a small one-storey house, but in 1762 a new, larger main building was added. Blunt (2004), p. 219. In Hammarby, Linnaeus made a garden where he could grow plants that could not be grown in the Botanical Garden in Uppsala. He began constructing a museum on a hill behind Hammarby in 1766, where he moved his library and collection of plants. A fire that destroyed about one third of Uppsala and had threatened his residence there necessitated the move. Blunt (2004), pp. 220–224. Since the initial release of ' in 1735, the book had been expanded and reprinted several times; the 10th edition of Systema Naturae, tenth edition was released in 1758. This edition established itself as the starting point for zoological nomenclature, the equivalent of '. Blunt (2004), p. 6. The Swedish King Adolf Frederick granted Linnaeus nobility in 1757, but he was not ennobled until 1761. With his ennoblement, he took the name Carl von Linné (Latinised as '), 'Linné' being a shortened and French language, gallicised version of 'Linnæus', and the German nobiliary particle 'von' signifying his ennoblement. The noble family's coat of arms prominently features a Linnaea borealis, twinflower, one of Linnaeus's favourite plants; it was given the scientific name ''Linnaea borealis'' in his honour by Jan Frederik Gronovius, Gronovius. The shield in the coat of arms is divided into thirds: red, black and green for the three kingdoms of nature (animal, mineral and vegetable) in Linnaean classification; in the centre is an egg "to denote Nature, which is continued and perpetuated ''in ovo''." At the bottom is a phrase in Latin, borrowed from the Aeneid, which reads "''Famam extendere factis''": we extend our fame by our deeds. Blunt (2004), p. 199. Blunt (2004), pp. 229–230. Linnaeus inscribed this personal motto in books that were given to him by friends. After his ennoblement, Linnaeus continued teaching and writing. His reputation had spread over the world, and he corresponded with many different people. For example, Catherine II of Russia sent him seeds from her country.Uppsala University, Linné Online
English language version
He also corresponded with Giovanni Antonio Scopoli, "the Linnaeus of the Austrian Empire", who was a doctor and a botanist in Idrija, Duchy of Carniola (nowadays Slovenia). Scopoli communicated all of his research, findings, and descriptions (for example of the olm and the dormouse, two little animals hitherto unknown to Linnaeus). Linnaeus greatly respected Scopoli and showed great interest in his work. He named a solanaceous genus, ''Scopolia'', the source of scopolamine, after him, but because of the great distance between them, they never met.


Final years

Linnaeus was relieved of his duties in the Royal Swedish Academy of Science in 1763, but continued his work there as usual for more than ten years after. In 1769 he was elected to the American Philosophical Society for his work. He stepped down as rector at Uppsala University in December 1772, mostly due to his declining health. Blunt (2004), p. 245. Linnaeus's last years were troubled by illness. He had suffered from a disease called the Uppsala fever in 1764, but survived thanks to the care of Rosén. He developed sciatica in 1773, and the next year, he had a stroke which partially paralysed him. Blunt (2004), p. 232. He suffered a second stroke in 1776, losing the use of his right side and leaving him bereft of his memory; while still able to admire his own writings, he could not recognise himself as their author. Stöver (1794), pp. 243–245. Broberg (2006), p. 42. In December 1777, he had another stroke which greatly weakened him, and eventually led to his death on 10 January 1778 in Hammarby. Despite his desire to be buried in Hammarby, he was buried in Uppsala Cathedral on 22 January. Quammen (2007), p. 4. Anderson (1997), pp. 104–106. His library and collections were left to his widow Sara and their children. Joseph Banks, an eminent botanist, wished to purchase the collection, but his son Carl refused the offer and instead moved the collection to Uppsala. In 1783 Carl died and Sara inherited the collection, having outlived both her husband and son. She tried to sell it to Banks, but he was no longer interested; instead an acquaintance of his agreed to buy the collection. The acquaintance was a 24-year-old medical student, James Edward Smith, who bought the whole collection: 14,000 plants, 3,198 insects, 1,564 shells, about 3,000 letters and 1,600 books. Smith founded the Linnean Society of London five years later. Blunt (2001), pp. 238–240. The von Linné name ended with his son Carl, who never married. His other son, Johannes, had died aged 3. There are over two hundred descendants of Linnaeus through two of his daughters.


Apostles

During Linnaeus's time as Professor and Rector of Uppsala University, he taught List of students of Linnaeus, many devoted students, 17 of whom he called "apostles". They were the most promising, most committed students, and all of them made botanical expeditions to various places in the world, often with his help. The amount of this help varied; sometimes he used his influence as Rector to grant his apostles a scholarship or a place on an expedition. Blunt (2004), pp. 189–190. To most of the apostles he gave instructions of what to look for on their journeys. Abroad, the apostles collected and organised new plants, animals and minerals according to Linnaeus's system. Most of them also gave some of their collection to Linnaeus when their journey was finished. Broberg (2006), pp. 37–39. Thanks to these students, the Linnaean system of taxonomy spread through the world without Linnaeus ever having to travel outside Sweden after his return from Holland. Anderson (1997), pp. 92–93. The British botanist William T. Stearn notes, without Linnaeus's new system, it would not have been possible for the apostles to collect and organise so many new specimens. Blunt (2004), pp. 184–185. Many of the apostles died during their expeditions.


Early expeditions

Christopher Tärnström, the first apostle and a 43-year-old pastor with a wife and children, made his journey in 1746. He boarded a Swedish East India Company ship headed for China. Tärnström never reached his destination, dying of a tropical fever on Côn Sơn Island the same year. Tärnström's widow blamed Linnaeus for making her children fatherless, causing Linnaeus to prefer sending out younger, unmarried students after Tärnström. Blunt (2004), pp. 185–186. Six other apostles later died on their expeditions, including Pehr Forsskål and Pehr Löfling. Two years after Tärnström's expedition, Finnish-born Pehr Kalm set out as the second apostle to North America. There he spent two-and-a-half years studying the flora and fauna of Pennsylvania, New York, New Jersey and Canada. Linnaeus was overjoyed when Kalm returned, bringing back with him many pressed flowers and seeds. At least 90 of the 700 North American species described in ''Species Plantarum'' had been brought back by Kalm. Anderson (1997), pp. 93–94.


Cook expeditions and Japan

Daniel Solander was living in Linnaeus's house during his time as a student in Uppsala. Linnaeus was very fond of him, promising Solander his eldest daughter's hand in marriage. On Linnaeus's recommendation, Solander travelled to England in 1760, where he met the English botanist Joseph Banks. With Banks, Solander joined James Cook on his expedition to Oceania on the ''HM Bark Endeavour, Endeavour'' in 1768–71. Anderson (1997), p. 96. Blunt (2004), pp. 191–192. Solander was not the only apostle to journey with James Cook; Anders Sparrman followed on the ''HMS Resolution (1771), Resolution'' in 1772–75 bound for, among other places, Oceania and South America. Sparrman made many other expeditions, one of them to South Africa. Blunt (2004), pp. 192–193. Perhaps the most famous and successful apostle was Carl Peter Thunberg, who embarked on a nine-year expedition in 1770. He stayed in South Africa for three years, then travelled to Japan. All foreigners in Japan were forced to stay on the island of Dejima outside Nagasaki, so it was thus hard for Thunberg to study the flora. He did, however, manage to persuade some of the translators to bring him different plants, and he also found plants in the gardens of Dejima. He returned to Sweden in 1779, one year after Linnaeus's death. Blunt (2004), pp. 193–194.


Major publications


''Systema Naturae''

The first edition of ' was printed in the Netherlands in 1735. It was a twelve-page work.#L1735, Linnaeus (1735) By the time it reached its 10th edition of Systema Naturae, 10th edition in 1758, it classified 4,400 species of animals and 7,700 species of plants. People from all over the world sent their specimens to Linnaeus to be included. By the time he started work on the 12th edition, Linnaeus needed a new invention—the index card—to track classifications. In ''Systema Naturae'', the unwieldy names mostly used at the time, such as "'", were supplemented with concise and now familiar "binomials", composed of the generic name, followed by a specific epithet—in the case given, ''Physalis angulata''. These binomials could serve as a label to refer to the species. Higher taxa were constructed and arranged in a simple and orderly manner. Although the system, now known as
binomial nomenclature In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species In biology, a species is the basic unit of biological classi ...
, was partially developed by the Bauhin brothers (see Gaspard Bauhin and Johann Bauhin) almost 200 years earlier, Linnaeus was the first to use it consistently throughout the work, including in monospecific genera, and may be said to have popularised it within the scientific community. After the decline in Linnaeus's health in the early 1770s, publication of editions of ''Systema Naturae'' went in two different directions. Another Swedish scientist, Johan Andreas Murray issued the ''Regnum Vegetabile'' section separately in 1774 as the ''Systema Vegetabilium'', rather confusingly labelled the 13th edition. Meanwhile, a 13th edition of the entire ''Systema'' appeared in parts between 1788 and 1793. It was through the ''Systema Vegetabilium'' that Linnaeus's work became widely known in England, following its translation from the Latin by the Lichfield Botanical Society as ''A System of Vegetables'' (1783–1785).


''Orbis eruditi judicium de Caroli Linnaei MD scriptis''

('Opinion of the learned world on the writings of Carl Linnaeus, Doctor') Published in 1740, this small octavo-sized pamphlet was presented to the State Library of New South Wales by the Linnean Society of NSW in 2018. This is considered among the rarest of all the writings of Linnaeus, and crucial to his career, securing him his appointment to a professorship of medicine at Uppsala University. From this position he laid the groundwork for his radical new theory of classifying and naming organisms for which he was considered the founder of modern taxonomy.


'

' (or, more fully, ') was first published in 1753, as a two-volume work. Its prime importance is perhaps that it is the primary starting point of botanical nomenclature, plant nomenclature as it exists today.


'

' was first published in 1737, delineating plant genera. Around 10 editions were published, not all of them by Linnaeus himself; the most important is the 1754 fifth edition.#Stace, Stace (1991)
p. 22
In it Linnaeus divided the plant Kingdom into 24 classes. One, Cryptogamia, included all the plants with concealed reproductive parts (algae, fungi, mosses and liverworts and ferns).#Hoek, Van den Hoek ''et al.'' (2005).


'

' (1751) was a summary of Linnaeus's thinking on plant classification and nomenclature, and an elaboration of the work he had previously published in ' (1736) and ' (1737). Other publications forming part of his plan to reform the foundations of botany include his ' and ': all were printed in Holland (as were ' (1737) and ' (1735)), the ''Philosophia'' being simultaneously released in Stockholm.


Collections

At the end of his lifetime the Linnean collection in Uppsala was considered one of the finest collections of natural history objects in Sweden. Next to his own collection he had also built up a museum for the university of Uppsala, which was supplied by material donated by Carl Gyllenborg (in 1744–1745), crown-prince Adolf Frederick, King of Sweden, Adolf Fredrik (in 1745), Erik Petreus (in 1746), Claes Grill (in 1746), Magnus Lagerström (in 1748 and 1750) and Jonas Alströmer (in 1749). The relation between the museum and the private collection was not formalised and the steady flow of material from Linnean pupils were incorporated to the private collection rather than to the museum.Wallin, L. 2001.
Catalogue of type specimens. 4. Linnaean specimens. – pp. [1], 1–128. Uppsala. (Uppsala University, Museum of Evolution, Zoology Section).
Linnaeus felt his work was reflecting the harmony of nature and he said in 1754 "the earth is then nothing else but a museum of the all-wise creator's masterpieces, divided into three chambers". He had turned his own estate into a microcosm of that 'world museum'. In April 1766 parts of the town were destroyed by a fire and the Linnean private collection was subsequently moved to a barn outside the town, and shortly afterwards to a single-room stone building close to his Linnaeus's Hammarby, country house at Hammarby near Uppsala. This resulted in a physical separation between the two collections; the museum collection remained in the botanical garden of the university. Some material which needed special care (alcohol specimens) or ample storage space was moved from the private collection to the museum. In Hammarby the Linnean private collections suffered seriously from damp and the depredations by mice and insects. Carl von Linné's son (Carl Linnaeus) inherited the collections in 1778 and retained them until his own death in 1783. Shortly after Carl von Linné's death his son confirmed that mice had caused "horrible damage" to the plants and that also moths and mould had caused considerable damage.Dance, S.P. 1967. Report on the Linnaean shell collection. – Proceedings of the Linnean Society of London 178 (1): 1–24, Pl. 1–10. He tried to rescue them from the neglect they had suffered during his father's later years, and also added further specimens. This last activity however reduced rather than augmented the scientific value of the original material. In 1784 the young medical student James Edward Smith purchased the entire specimen collection, library, manuscripts, and correspondence of Carl Linnaeus from his widow and daughter and transferred the collections to London. Not all material in Linné's private collection was transported to England. Thirty-three fish specimens preserved in alcohol were not sent and were later lost. In London Smith tended to neglect the zoological parts of the collection; he added some specimens and also gave some specimens away. Over the following centuries the Linnean collection in London suffered enormously at the hands of scientists who studied the collection, and in the process disturbed the original arrangement and labels, added specimens that did not belong to the original series and withdrew precious original type material. Much material which had been intensively studied by Linné in his scientific career belonged to the collection of Louisa Ulrika of Prussia, Queen Lovisa Ulrika (1720–1782) (in the Linnean publications referred to as "Museum Ludovicae Ulricae" or "M. L. U."). This collection was donated by her grandson Gustav IV Adolf of Sweden, King Gustav IV Adolf (1778–1837) to the museum in Uppsala in 1804. Another important collection in this respect was that of her husband Adolf Frederick, King of Sweden, King Adolf Fredrik (1710–1771) (in the Linnean sources known as "Museum Adolphi Friderici" or "Mus. Ad. Fr."), the wet parts (alcohol collection) of which were later donated to the Royal Swedish Academy of Sciences, and is today housed in the Swedish Museum of Natural History at Stockholm. The dry material was transferred to Uppsala.


System of taxonomy

The establishment of universally accepted conventions for the naming of organisms was Linnaeus's main contribution to taxonomy—his work marks the starting point of consistent use of binomial nomenclature.#Reveal, Reveal & Pringle (1993), pp. 160–161. During the 18th century expansion of natural history knowledge, Linnaeus also developed what became known as the ''Linnaean taxonomy''; the system of scientific classification now widely used in the biology, biological sciences. A previous zoologist Rumphius (1627–1702) had more or less approximated the Linnaean system and his material contributed to the later development of the binomial scientific classification by Linnaeus. The Linnaean system classified nature within a nested hierarchy, starting with three kingdom (biology), kingdoms. Kingdoms were divided into classes and they, in turn, into orders, and thence into genera (''singular:'' genus), which were divided into species (''singular:'' species). Below the rank of species he sometimes recognised taxa of a lower (unnamed) taxonomic rank, rank; these have since acquired standardised names such as ''variety'' in botany and ''subspecies'' in zoology. Modern taxonomy includes a rank of Family (biology), family between order and genus and a rank of phylum between kingdom and class that were not present in Linnaeus's original system.#Davis, Davis & Heywood (1973), p. 17. Linnaeus's groupings were based upon shared physical characteristics, and not simply upon differences. Of his higher groupings, only those for animals are still in use, and the groupings themselves have been significantly changed since their conception, as have the principles behind them. Nevertheless, Linnaeus is credited with establishing the idea of a hierarchical structure of classification which is based upon observable characteristics and intended to reflect natural relationships. While the underlying details concerning what are considered to be scientifically valid "observable characteristics" have changed with expanding knowledge (for example, DNA sequencing, unavailable in Linnaeus's time, has proven to be a tool of considerable utility for classifying living organisms and establishing their Phylogenetics, evolutionary relationships), the fundamental principle remains sound.


Human taxonomy

Linnaeus's system of taxonomy was especially noted as the first to include humans (''Homo'') taxonomically grouped with apes (''Simia''), under the header of ''Anthropomorpha''. German biologist Ernst Haeckel speaking in 1907 noted this as the "most important sign of Linnaeus's genius". Linnaeus classified humans among the primates beginning with the first edition of '. During his time at Hartekamp, he had the opportunity to examine several monkeys and noted similarities between them and man. He pointed out both species basically have the same anatomy; except for speech, he found no other differences.#Frängsmyr, Frängsmyr ''et al.'' (1983), p. 170.#Frängsmyr, Frängsmyr ''et al.'' (1983), p. 167, quotes Linnaeus explaining the real difference would necessarily be absent from his classification system, as it was not a morphology (biology), morphological characteristic: ''"I well know what a splendidly great difference there is [between] a man and a ''bestia'' [literally, "beast"; that is, a non-human animal] when I look at them from a point of view of morality. Man is the animal which the Creator deity#Christianity, Creator has seen fit to honor with such a magnificent mind and has condescended to adopt as his favorite and for which he has prepared a nobler life"''. See als
books.google.com
in which Linnaeus cites the significant capacity to reason as the distinguishing characteristic of humans.
Thus he placed man and monkeys under the same category, ''Anthropomorpha'', meaning "manlike."#Frängsmyr, Frängsmyr ''et al.'' (1983), p. 167. This classification received criticism from other biologists such as Johan Gottschalk Wallerius, Jacob Theodor Klein and Johann Georg Gmelin on the ground that it is illogical to describe man as human-like. In a letter to Gmelin from 1747, Linnaeus replied:
It does not please [you] that I've placed Man among the Anthropomorpha, perhaps because of the term 'with human form',"antropomorphon" but man learns to know himself. Let's not quibble over words. It will be the same to me whatever name we apply. But I seek from you and from the whole world a generic difference between man and simian that [follows] from the principles of Natural History.Others who followed were more inclined to give humans a special place in classification; Johann Friedrich Blumenbach in the first edition of his ''Manual of Natural History'' (1779), proposed that the primates be divided into the Quadrumana (four-handed, i.e. apes and monkeys) and Bimana (two-handed, i.e. humans). This distinction was taken up by other naturalists, most notably Georges Cuvier. Some elevated the distinction to the level of order (biology), order. However, the many affinities between humans and other primates—and especially the great apes—made it clear that the distinction made no scientific sense. Charles Darwin wrote, in ''The Descent of Man, and Selection in Relation to Sex, The Descent of Man'' in 1871:
The greater number of naturalists who have taken into consideration the whole structure of man, including his mental faculties, have followed Johann Friedrich Blumenbach, Blumenbach and Georges Cuvier, Cuvier, and have placed man in a separate Order, under the title of the Bimana, and therefore on an equality with the orders of the Quadrumana, Carnivora, etc. Recently many of our best naturalists have recurred to the view first propounded by Linnaeus, so remarkable for his sagacity, and have placed man in the same Order with the Quadrumana, under the title of the Primates. The justice of this conclusion will be admitted: for in the first place, we must bear in mind the comparative insignificance for classification of the great development of the brain in man, and that the strongly marked differences between the skulls of man and the Quadrumana (lately insisted upon by Theodor Ludwig Wilhelm Bischoff, Bischoff, Christoph Theodor Aeby, Aeby, and others) apparently follow from their differently developed brains. In the second place, we must remember that nearly all the other and more important differences between man and the Quadrumana are manifestly adaptive in their nature, and relate chiefly to the erect position of man; such as the structure of his hand, foot, and pelvis, the curvature of his spine, and the position of his head.
I absolutely know of none. If only someone might tell me a single one! If I would have called man a simian or vice versa, I would have brought together all the theologians against me. Perhaps I ought to have by virtue of the law of the discipline.
The theological concerns were twofold: first, putting man at the same level as monkeys or apes would lower the spiritually higher position that man was assumed to have in the great chain of being, and second, because the Bible says man was created in the image of God (theomorphism), if monkeys/apes and humans were not distinctly and separately designed, that would mean monkeys and apes were created in the image of God as well. This was something many could not accept.#Frängsmyr, Frängsmyr ''et al.'' (1983), pp. 171–172. The conflict between world views that was caused by asserting man was a type of animal would simmer for a century until the much greater, and still ongoing, creation–evolution controversy began in earnest with the publication of ''On the Origin of Species'' by Charles Darwin in 1859. After such criticism, Linnaeus felt he needed to explain himself more clearly. The 10th edition of ' introduced new terms, including ''Mammalia'' and ''Primates'', the latter of which would replace ''Anthropomorpha''#Frängsmyr, Frängsmyr ''et al.'' (1983), p. 175. as well as giving humans the full binomial ''Homo sapiens''. Blunt (2004), p. 8. The new classification received less criticism, but many natural historians still believed he had demoted humans from their former place of ruling over nature and not being a part of it. Linnaeus believed that man biologically belongs to the animal kingdom and had to be included in it.#Frängsmyr, Frängsmyr ''et al.'' (1983), pp. 191–192. In his book ', he said, "One should not vent one's wrath on animals, Theology decree that man has a soul and that the animals are mere 'aoutomata mechanica,' but I believe they would be better advised that animals have a soul and that the difference is of nobility."#Frängsmyr, Frängsmyr ''et al.'' (1983), p. 166. Linnaeus added a second species to the genus ''Homo'' in ' based on a figure and description by Jacobus Bontius from a 1658 publication: ''Homo troglodytes'' ("caveman")#Bontius, Bontius (1658)
p. 84
and published a third in 1771: ''Homo lar''. Swedish historian Gunnar Broberg states that the new human species Linnaeus described were actually simians or native people clad in skins to frighten colonial settlers, whose appearance had been exaggerated in accounts to Linnaeus.#Frängsmyr, Frängsmyr ''et al.'' (1983), p. 187. In early editions of ', many well-known legendary creatures were included such as the Phoenix (mythology), phoenix, dragon, manticore, and satyrus (ape), satyrus, which Linnaeus collected into the catch-all category ''Animalia Paradoxa, Paradoxa''. Broberg thought Linnaeus was trying to offer a natural explanation and demystify the world of superstition.#Frängsmyr, Frängsmyr ''et al.'' (1983), pp. 176–177. Linnaeus tried to debunk some of these creatures, as he had with the hydra; regarding the purported remains of dragons, Linnaeus wrote that they were either derived from lizards or rays. For ''Homo troglodytes'' he asked the Swedish East India Company to search for one, but they did not find any signs of its existence.#Frängsmyr, Frängsmyr ''et al.'' (1983), p. 186. ''Homo lar'' has since been reclassified as ''Hylobates lar'', the lar gibbon. In the first edition of ', Linnaeus subdivided the human species into four Race (biology), varieties based on continent and human skin color, skin colour: "Europæus albesc[ens]" (whitish European), "Americanus rubesc[ens]" (reddish American), "Asiaticus fuscus" (tawny Asian) and "Africanus nigr[iculus]" (blackish African). In the tenth edition of Systema Naturae he further detailed phenotypical characteristics for each variety, based on the concept of the four temperaments from classical antiquity, and changed the description of Asians' skin tone to "luridus" (yellow). Additionally, Linnaeus created a wastebasket taxon "monstrosus" for "wild and monstrous humans, unknown groups, and more or less abnormal people". In 1959, W. T. Stearn designated Linnaeus to be the lectotype of ''H. sapiens''.


Influences and economic beliefs

Linnaeus's applied science was inspired not only by the instrumental utilitarianism general to the early Enlightenment, but also by his adherence to the older economic doctrine of Cameralism. Koerner (1999), p. 95–96. Additionally, Linnaeus was a state interventionist. He supported tariffs, levies, export bounties, quotas, embargoes, navigation acts, subsidised investment capital, ceilings on wages, cash grants, state-licensed producer monopolies, and cartels. Koerner (1999), p. 97.


Commemoration

Anniversaries of Linnaeus's birth, especially in centennial years, have been marked by major celebrations.#Östholm, Östholm (2007) Linnaeus has appeared on numerous Swedish postage stamps and banknotes. There are numerous statues of Linnaeus in countries around the world. The Linnean Society of London has awarded the Linnean Medal for excellence in botany or zoology since 1888. Following approval by the Riksdag of Sweden, Växjö University and Kalmar College merged on 1 January 2010 to become Linnaeus University. Other things named after Linnaeus include the twinflower genus ''Linnaea'', ''Linnaeosicyos'' (a monotypic genus in the family Cucurbitaceae), the crater Linné (crater), Linné on the Earth's moon, a street in Cambridge, Massachusetts, and the cobalt sulfide mineral Linnaeite.


Commentary

Andrew Dickson White wrote in ''A History of the Warfare of Science with Theology in Christendom'' (1896):
Linnaeus ... was the most eminent naturalist of his time, a wide observer, a close thinker; but the atmosphere in which he lived and moved and had his being was saturated with biblical theology, and this permeated all his thinking. ... Toward the end of his life he timidly advanced the hypothesis that all the species of one genus constituted at the creation one species; and from the last edition of his ''Systema Naturæ'' he quietly left out the strongly orthodox statement of the fixity of each species, which he had insisted upon in his earlier works. ... warnings came speedily both from the Catholic and Protestant sides.
The mathematical PageRank algorithm, applied to 24 multilingual Wikipedia editions in 2014, published in ''PLOS ONE'' in 2015, placed Carl Linnaeus at the top historical figure, above Jesus, Aristotle, Napoleon, and Adolf Hitler (in that order). In the 21st century, Linnæus's taxonomy of human "races" has been problematised and discussed. Some critics claim that Linnæus was one of the forebears of the modern pseudoscientific notion of scientific racism, while others hold the view that while his classification was stereotyped, it did not imply that certain human "races" were superior to others.
